Abstract:

The freezer machine is one of the tools on board and serves to maintain the temperature of food ingredients to keep it in good condition and fresh. Given the importance of this, the cooling machine is a tool that functions to make durable foodstuffs by naturally maintaining the temperature. Standard freezer machines produce temperatures only up to -15oC. Modification of the freezer machine needs to be done so that the temperature reaches a lower minus again by changing the capillary pipe from standard to double helical. The purpose of this study is to analyze the effect of double helical capil

Abstract:

In Ukraine, the production of pipes is one of the most important branches of industry. These are the oil, gas, food, chemical, machine-building, aviation, and construction materials industries. Pipes made of highly alloyed, corrosion-resistant steels are especially widely used. The process of producing steel pipes by pressing on hydraulic presses has become widespread. When pressed, the metal undergoes three-way compression, so it exhibits high plasticity, which is especially important for highly alloyed steels that are difficult to deform. In contrast to pipe rolling plants, it is possible to

Abstract. Plugging of soil pipes can be detrimental to hillslope stability. A soil pipe commonly becomes plugged through internal erosion when the pipe wall collapses. When a pipe becomes plugged, a pressure buildup occurs upslope from the plug. This pressure may be enough to remove the plug, or the pressure may continue to build in the soil matrix, which may lead to hillslope failures. Based on field observations, it is known that both processes occur, but limited data exist to understand if and when plug removal or pressure buildup occurs or how to model these processes.

Abstract:

Soil erosion is one of the most significant challenges for soil management and agri-food production threatening human habitat and livelihood. Although soil erosion due to surficial processes is well-studied, erosion due to subsurface processes such as internal soil pipes has often been overlooked. Internal soil pipes directly contribute to the total soil loss in agricultural fields and impede agricultural sustainability. Locating, measuring, and mapping internal soil pipes and their networks are vital to assessing the total soil loss in agricultural fields. Their hidden and uncorrelated nature

ABSTRACT Food manufacturers often use squeegees as a tool to remove condensation from overhead surfaces. This practice is done to reduce the likelihood of environmental pathogen contamination by eliminating condensed-water droplets that could fall from overhead surfaces during production.

Abstract:

The fisheries and aquaculture industries are vital components of global food production, yet they also contribute to release of microplastics into marine environments, posing risks to ecosystem health and seafood safety. Among the contributing factors, the erosion of feeding pipes during the pneumatic conveyance of fish feed pellets stands out as a significant source of microplastic pollution. This study focuses on optimizing feed pellet conveying systems in fish farms to minimize microplastic emissions while maximizing pipeline lifespan and pellet integrity.

Subsequently, the energy resources depletion, for instance, in power plant, air-conditioning system and food processing systems. The important field for saving energy was through improving thermal performance, which can provide high performance heat exchanger. Present enhancing approaches can be classified by three changed types, which are passive technique, active technique and compound technique.

Abstract:

The present work deals with a thermo-fluid analysis of a collinear cylindrical ohmic heater in laminar flow. The geometry of interest is a circular electrically insulated glass pipe with two electrodes at the pipe ends. For this application, since the electrical conductivity of a liquid food depends strongly on the temperature, the thermal analysis of an ohmic heater requires the simultaneous solution of the electric and thermal fields. In the present work the analysis involves decoupling the previous fields by means of an iterative procedure. The thermal field has been calculated using an ana

Thus, an automatic feeder is needed to dispense food at a predetermined time. The advantages of automatic feeders are cost-effective, reduce labor requirements, and allow large volumes of feed to feed efficiently. Autofeeder is a modern fish feeder that can be used in several ponds. Therefore, in this research, the Autofeeder has been made with PVC pipe for the feed thrower.

As part of a biofilm in a floor drain, Listeria monocytogenes is exceedingly difficult to eradicate with standard sanitizing protocols. The objective of these studies was to test the use of ultrasonication to break up biofilm architecture and allow chemical sanitizers to contact cells directly. L. monocytogenes biofilms were created in model polyvinyl chloride drain pipes. Chemical sanitizers (quaternary ammonium, peroxide, or chlorine) were applied to the drain pipes with and without a 30-s ultrasonication treatment. Controls using sterile water were included for comparison. L. monocytogenes

Abstract Tribolium castaneum (Herbst) (Coleoptera: Tenebrionidae) and Trogoderma variabile Ballion (Coleoptera: Dermestidae) are two stored-product insects that cause extensive damage to a variety of postharvest commodities. Long-lasting insecticide-incorporated netting (LLIN), commonly used to control vector-borne diseases in tropical regions, has only been recently studied in an agricultural setting. While prior research showed that LLIN was successful against stored-product beetles, little is known about differential susceptibility among stored-product insect life stages. The aim of this st

Scanning electron microscopy observation was used to investigate the adhesion of Escherichia coli O157:H7 on water distribution pipe surfaces such as copper and polyethylene plastic at different contact times and storage temperatures. Our results indicated that E. coli cells could easily attach to both surface types after exposures as short as 1 or 4 h at ambient (20°C) and refrigeration temperatures (4°C). Also, we found that copper surfaces have a higher number of attached E. coli cells than plastic surfaces. The number of cells attached to each type of material depended on the nature of the
