Abstract:

To avoid any type of cross-contamination, residue-free production equipment is of utmost importance in the pharmaceutical industry. The equipment cleaning for continuous processes such as hot melt extrusion (HME), which has recently gained popularity in pharmaceutical applications, necessitates extensive manual labour and costs. The present work tackles the HME cleaning issue by investigating two cleaning strategies following the extrusion of polymeric formulations of a hormonal drug and for a sustained release formulation of a poorly soluble drug. First, an in-line quantification by means of UV–Vis spectroscopy was successfully implemented to assess very low active pharmaceutical ingredient (API) concentrations in the extrudates during a cleaning procedure for the first time. Secondly, a novel in-situ solvent-based cleaning approach was developed and its usability was evaluated and compared to a polymer-based cleaning sequence. Comparing the in-line data to typical swab and rinse tests of the process equipment indicated that inaccessible parts of the equipment were still contaminated after the polymer-based cleaning procedure, although no API was detected in the extrudate. Nevertheless, the novel solvent-based cleaning approach proved to be suitable for removing API residue from the majority of problematic equipment parts and can potentially enable a full API cleaning-in-place of a pharmaceutical extruder for the first time.

Abstract:

Cleaning-in-place (CIP) is a critical process across various industries, particularly in the food industry, where maintaining sanitation without equipment disassembly is imperative. However, challenges such as cross-contamination and escalating sanitation costs may arise when protocols are not diligently followed. This research focuses on optimizing the CIP techniques to mitigate milk fouling deposits in the dairy industry by strategically manipulating cleaning parameters. A physical model using raw milk to simulate industrial scenarios was prepared, followed by laboratory-scale sanitation experiments. Here, the Box–Behnken experimental design was employed to determine the optimal cleaning parameters for the detergent cycle step. The investigation evaluated the effects of temperatures (30°C, 50°C, 70°C), mixing ratio of cleaning solution (water: cleaning detergent) (0:50, 1:50, 1:100), and fluid velocities (0.5 m/s, 1.0 m/s, 1.5 m/s) on the removal of milk fouling deposits. The cleaning solution used in this work falls under the anionic chemical family and was used to clean equipment in the food industry. The cleaning time for the removal of milk fouling deposits was measured during the sanitation experiments. The optimal conditions were found at 60°C, detergent ratio 1:83, and fluid velocity 1.5 m/s, reducing cleaning time to 11.58 minutes for 100% removal from stainless-steel surfaces. These findings challenge the commonly practiced 30-minute detergent cycle step, highlighting potential time and cost savings. The study highlights temperature and fluid velocity's vital role in enhancing CIP efficiency, providing practical insights for dairy industry improvements.

Abstract:

Systematically testing alternative cleaning agents and cleaning procedures on a large scale municipal membrane bioreactor, the Erftverband optimized the cleaning strategies and refined the original cleaning procedures for the hollow fiber membranes in use. A time-consuming, intensive ex-situ membrane cleaning twice a year was initially the regular routine. By introducing the effective means of cleaning in place in use today, which employs several acidic and oxidative/alkaline cleaning steps, intensive membrane cleaning could be delayed for years. An overview and an assessment of various cleaning strategies for large scale plants are given.

Abstract:

Clean-in-place (CIP) processes are extensively used to clean industrial equipment without the need for disassembly. In food manufacturing, cleaning can account for up to 70% of water use and is also a heavy user of energy and chemicals. Due to a current lack of real-time in-process monitoring, the non-optimal control of the cleaning process parameters and durations result in excessive resource consumption and periods of non-productivity. In this paper, an optical monitoring system is designed and realized to assess the amount of fouling material remaining in process tanks, and to predict the required cleaning time. An experimental campaign of CIP tests was carried out utilizing white chocolate as fouling medium. During the experiments, an image acquisition system endowed with a digital camera and ultraviolet light source was employed to collect digital images from the process tank. Diverse image segmentation techniques were considered to develop an image processing procedure with the aim of assessing the area of surface fouling and the fouling volume throughout the cleaning process. An intelligent decision-making support system utilizing nonlinear autoregressive models with exogenous inputs (NARX) Neural Network was configured, trained and tested to predict the cleaning time based on the image processing results. Results are discussed in terms of prediction accuracy and a comparative study on computation time against different image resolutions is reported. The potential benefits of the system for resource and time efficiency in food manufacturing are highlighted.

Abstract:

Background/Aims: The recommendations on the time interval between pre-cleaning and reprocessing of endoscopes differ in international guidelines, with a low level of evidence. The aim of this study was to investigate the influence of postponing reprocessing on the reprocessing quality after pre-cleaning the flexible endoscopes.Methods: We reprocessed 124 standardized test tubes simulating endoscope channels after soiling and contamination and determined the reprocessing performance. In addition, we examined contaminated gastroscopes, colonoscopes, and bronchoscopes. The duration of interim storage after pre-cleaning was 16 h for 100 test tubes and up to 24 h for 18 endoscopes. We determined the residual protein content and germ load as markers for cleaning and disinfection performance. In addition, we determined biofilm formation by photometry of crystal violet staining.Results: All test tubes and flexible endoscopes showed residual protein content and germ load significantly below legally prescribed threshold values, independent of the interval between pre-cleaning and reprocessing.Conclusions: Our findings indicate that flexible endoscopes could be stored overnight after pre-cleaning without any influence on the quality of reprocessing. While ensuring patient safety, this could simplify logistical processes and enable cost savings.

Abstract:

Membrane filtration is a key technology in dairy processing for the separation of dairy liquids to clarify, concentrate, and fractionate a variety of dairy products. Ultrafiltration (UF) is widely applied for whey separation, protein concentration and standardization, and lactose-free milk production, though its performance can be hindered by membrane fouling. As an automated cleaning process commonly used in the food and beverage industries, cleaning in place (CIP) uses large amounts of water, chemicals, and energy, resulting in significant environmental impacts. This study introduced micron-scale air-filled bubbles (microbubbles; MBs) with mean diameters smaller than 5 μm into cleaning liquids to clean a pilot-scale UF system. During the UF of model milk for concentration, cake formation was identified as the dominant membrane fouling mechanism. The MB-assisted CIP process was conducted at two bubble number densities (2021 and 10,569 bubbles per mL of cleaning liquid) and two flow rates (130 and 190 L/min). For all the cleaning conditions tested, MB addition largely increased the membrane flux recovery by 31–72%; however, the effects of bubble density and flow rate were insignificant. Alkaline wash was found to be the main step in removing proteinaceous foulant from the UF membrane, though MBs did not show a significant effect on the removal due to the operational uncertainty of the pilot-scale system. The environmental benefits of MB incorporation were quantified by a comparative life cycle assessment and the results indicated that MB-assisted CIP had up to 37% lower environmental impact than control CIP. This is the first study incorporating MBs into a full CIP cycle at the pilot scale and proving their effectiveness in enhancing membrane cleaning. This novel CIP process can help reduce water and energy use in dairy processing and improve the environmental sustainability of the dairy industry.

Abstract:

The dairy industry must focus on sanitation and hygiene requirements to ensure product safety, control of detergents, tanks, pumps. Compliance with these requirements will provide conditions for the production of a high-quality dairy product, maintenance of technical and mechanical frequency at the enterprise, and prevention of the reproduction of harmful bacteria. Under these conditions, the problem of cleaning technical equipment from harmful residues on site is urgent. The object of the study is the basic processes in the Cleaning-In-Place system in the dairy industry. It is recommended to design a human-machine interface for on-site cleaning in the Siemens WinCC Flexible software. It is worth noting that the proposed interface takes into account the reduction of equipment downtime during the washing of technological equipment, a convenient user interface, and ease of maintenance. The state of use of existing visualizations of on-site cleaning interfaces that do not use simultaneous washing of two tanks with cleaning solutions (alkaline and acid) and the state of controlled values in selected washing lines were evaluated. Numerical evaluations of the results use modern programming technology and high information productivity of the user interface. A human-machine interface was designed with the possibility of parallel cleaning of two tanks at different ends of the workshop and the selection of recipes for different groups of tanks. This interface displays emergency messages, the status of the washing process of production lines and control based on data from sensors. The practical use of the obtained scientific results is that the designed interface can be used not only in the dairy industry but in any other food industry

Abstract:

The Central Sterile Supply Department (CSSD) is one of the hospital's critical support services. It is a place to receive medical equipment blood-stained from the other departments to be cleaned. It is responsible for cleaning, receiving, storing, sterilizing, and returning medical equipment to everyone and delivered to different departments within the hospital. Nowadays, various cleaning and dissolving blood stains are used to clean and remove blood stains. This research aimed to compare the efficacy of pre-cleaning spray and pre-cleaning spray foam cleaners for blood-contaminated surgical instruments and medical devices in the Central Sterile Services Department. The pre-cleaning spray was significantly higher than the pre-cleaning spray foam (p ≤ .005). A significant difference in the 2-minute pre-cleaning spray was observed by using cleaning indicators. The pre-cleaning spray foam started dissolving blood after 5 minutes. Therefore, from the study, using the pre-cleaning spray for dissolving blood stains and pre-cleaning has a more practical effect than pre-cleaning foam.

Abstract:

SummaryTwo cleaning-in-place disinfectant Systems (alkaline–acid, alkaline–CI2) were tested on wild bacteria isolated from a milking line. Most of the isolated strains were Gram-negative and capsule-positive. The effect of milk and cream on the resistance of the wild strains to the cleaning Systems was tested. Suspension tests did not show the resistance of bacteria whereas the surface test showed high resistance towards all cleaning-agents. Milk had a protective effect only on the surfaces whereas cream showed mild protection in suspension and complete protection on the surfaces. It was concluded that the growth pattern of contaminants on surfaces needs further attention and the laboratory suspension tests do not correlate with the practical situation. Disinfectant tests based on bacterial growth on the surface are of importance.

Abstract When checking and cleaning whether there is carbon deposit in the cylinder of gasoline engine, it is often time-consuming and laborious, and the process is complicated. Once the disassembly and assembly is not in place, its service life will be affected. When cleaning with carburizing agent and cleaning agent, it is difficult to fully contact with the cylinder wall, so the cleaning effect is poor and it is easy to leave its chemical composition in the engine. In this paper, some common ways of engine cylinder cleaning are studied, and a device for detecting and cleaning carbon deposition in gasoline engine cylinder is designed. The purpose is to provide a new convenient, simple and practical method for detecting and cleaning carbon deposition in automobile engine cylinder in the current market.

Abstract:

One of the most effective methods for cleaning soil and water bodies from oil and oil products is the biotechnological method using oil-degrading bacteria. However, their production is a rather complicated process, during which many unfavorable factors act on the human body. The paper considers the process of cleaning an industrial fermenter with a CIP (Cleaning in Place) contactless cleaning system. An automatic metering valve for supplying direct steam during sterilization has been proposed. This reduces the human factor and the risk of workers being poisoned by surfactant species used to clean the fermenter.

Abstract:

Abstract A twenty-five-year-old vacuum furnace is being used for degassing of ultra-high vacuum components. The heat shield assembly of the furnace comprised of one molybdenum (Mo) front sheet, followed by four 304 stainless steel (SS) sheets. During prolonged service of the furnace, SS sheets developed thick black oxide scale. As a part of refurbishment drive, the SS sheets were subjected to chemical cleaning in 20 % HNO3 + 1.5 % HF, which caused severe thinning along the edges of some sheets. Detailed analysis of a damaged SS sheet showed that the damage was caused by severe sensitization of edge region which underwent extensive intergranular corrosion during chemical cleaning. Important remedial measures suggested to avoid similar failures included: (i) use of type 316L or stabilized grades of austenitic SS sheets, (ii) use of two Mo front sheets in place of one and (iii) use of mechanical cleaning in place of chemical cleaning.

Abstract:

In the dairy industry re-use and multi-use cleaning-in-place (CIP) systems are operated by circulating chemicals and water without taking the equipment apart. The solutions, which become polluted due to the removal of fouling compounds, are drained periodically when they are considered to be too polluted. This work shows the large variations in composition (pollution, surface tension, etc) of the industrial caustic solutions coming from milk standardization and pasteurization plant CIP throughout their life time (7 days) and from 1 week to another. The work is also intended to show how nanofiltration (1 kg mol−1 molecular weight cut-off) was robust and performed well, with good recovery of caustic solutions, even when faced with large variations of solutions composition: high caustic yield, permeation flux (J) in the range 42–110 l h−1 m−2, average chemical oxygen demand (COD) reduction equal to 0.58 and low surface tension change. Equations have been established for the prediction of J as a function of initial membrane hydraulic resistance (Rm) caustic concentration, volume reduction ratio (VRR) and initial soluble COD. When VRR increased, both J and pollution retention decreased despite the increase in irreversible fouling induced by the increase of soluble pollution concentration in retentate . The higher the initial soluble COD, the sharper the decrease in J vs. VRR. Since irreversible fouling was usually small (0.1–3.4×1013 m−1, that is to say of the same order of magnitude as Rm), the membrane cleaning could be efficiently performed by using single phase sodium hypochlorite alternately with a more expensive acid–base cleaning sequence. The obtained permeate was a clear regenerated cleaning solution with low soluble COD (0.2–3.5 g/l) and surface tension (56–30 mJ m−2) which could be successfully exploited owing to its cleaning potential.

Abstract:

The diversity of products in a company makes the process of cleaning production areas important to prevent cross contamination. Cleaning in Place (CIP) is a method to clean product residues from production equipment automatically without the need to disassemble the machine. This study aims to determine the required minimum time for the CIP drying process to dry the production equipment. The experiment was done by testing the treatment based on changes in compressed air, drying, and cooling process time. Cleaning verification was done by examining visual inspection and test for detection of microbial contamination, allergens and ATP. The results showed that reducing the CIP processing time can be done by minimizing the drying time. The best treatment resulted in the treatment with compressed air 300 s, drying 900 s and cooling 900 s. This can be seen from the 3 repetitions, the results obtained by examining the overall appearance of the surface in the tote bin are clean and dry. In addition, changes in the time parameter did not affect the cleaning process of residues on the surface of the tote bin, which was shown in the results of testing for detection of microbial contamination, allergens and ATP.

Abstract:

One of the main strategies for maintaining the optimal hygiene level in dairy processing facilities is regular cleaning and disinfection, which is incorporated in the cleaning-in-place (CIP) regimes. However, a frail point of the CIP procedures is their variable efficiency in eliminating biofilm bacteria. In the present study, we evaluated the susceptibility of strong biofilm-forming dairy Bacillus isolates to industrial cleaning procedures using two differently designed model systems. According to our results, the dairy-associated Bacillus isolates demonstrate a higher resistance to CIP procedures, compared to the non-dairy strain of B. subtilis. Notably, the tested dairy isolates are highly persistent to different parameters of the CIP operations, including the turbulent flow of liquid (up to 1 log), as well as the cleaning and disinfecting effects of commercial detergents (up to 2.3 log). Moreover, our observations indicate an enhanced resistance of poly-γ-glutamic acid (PGA)-overproducing B. subtilis, which produces high amounts of proteinaceous extracellular matrix, to the CIP procedures (about 0.7 log, compared to the wild-type non-dairy strain of B. subtilis). We therefore suggest that the enhanced resistance to the CIP procedures by the dairy Bacillus isolates can be attributed to robust biofilm formation. In addition, this study underlines the importance of evaluating the efficiency of commercial cleaning agents in relation to strong biofilm-forming bacteria, which are relevant to industrial conditions. Consequently, we believe that the findings of this study can facilitate the assessment and refining of the industrial CIP procedures.

Abstract:

In 2015, the results of United Nations research called out Indonesia as the second-largest contributor to plastic waste in the ocean, following China. This problem was, absolutely, inseparable from improper waste disposal behavior. This recent research was intended to prove the theory of planned behavior in the issue of throwing garbage in public places. Variables included in this case were attitude, subjective norms, perceived behavioral control, and intention. Questionnaires were distributed online and offline to people who had thrown out their garbage in public places. A total of 396 respondents were obtained, and the Confirmatory Factor Analysis (CFA) method of the Structural Equation Model (SEM) was used in this research with IBM SPSS 25 and AMOS 24 tools. This research found that the good value of public place visitors’ attitudes would develop their intention of throwing garbage properly. Visitors misunderstood the function of the cleaning service officers. They considering that their garbage would be taken care of by the cleaning service officers. The availability of trash cans in public places would support the visitors’ behavior in managing their garbage.

Abstract:

Cleanliness, hygiene and personal hygiene habits have an extremely important place in maintaining and developing an individual’s physical and spiritual health. In contrast, it has been observed that research on student behaviour for cleaning and hygiene applications has been limited in the literature. In this case, “What are the cleaning and hygiene habits of students?” It has emerged as a necessity to answer the question. In this study, mixed blending method has been used. The study group consisted of 1300 students, studying in 12 different secondary schools in the city of Kars. In order to collect data, personal information form, “Personal Cleansing and Hygiene Habits Scale” developed by the researcher and open-ended questions were used. It was observed that the general cleaning and hygiene levels of the students were not statistically significantly different according to gender variables (p>.05). In terms of the personal hygiene and hygiene habits of the students’ significant differences have been found according to their parents’ education status, the number of individuals in their families and the level of their education.
