Abstract:

This study is aimed to compare the fluidized bed and microwave drying with microwave assisted fluidized bed drying. For this purpose, macaroni beads (2.4&plusmn<br>0.08 mm diameter) were dried from about 20% to 12% moisture content in a fluidized bed of 7.6 cm diameter, in a domestic microwave oven with a power of 609 W and in the fluidized bed placed in the microwave oven conditions. In the experiments with the fluidized bed three air temperatures<br>50, 60 and 70&deg<br>C at an air velocity of 2.3 m/s and in those with the microwave oven two power levels<br>50% and 100% were used.

Abstract:

Spray drying is a technique that is widely applied to produce dry powders from their liquid or slurry states in the food and pharmaceutical industries. Spray-dried forms of dairy powders may have several advantages, such as greater solubility, dissolution rates and surface areas. However, they are thermodynamically-unstable solids, which may undergo undesirable changes, such as caking after production. To overcome this problem, a fluidized-bed dryer has been used in this study to improve the degree of lactose crystallinity of sweet whey. It has been found that, with controlling the operating

Abstract:

Atmospheric freeze drying (AFD) is the lyophilization of a product at atmospheric pressure conditions and temperatures ranging generally between -15 and -5 ◦C (avoiding, thereby, ice melting). The quality of the obtained dried products is quite similar to the quality of products dried by vacuum freeze drying (VFD), but without the need of generating vacuum, maintaining temperatures around -50 ◦C in the condenser, or defrosting it. There are several ways to carry out AFD, such as the use of a fluidized bed or a tunnel conveyor. Nevertheless, AFD involves considerably longer drying times than V

Wheat germ contains lipase and lipoxygenase, their activities are therefore necessary to be inhibited through roasting and drying treatments to prevent hydrolysis and oxidation of fatty acids. However, the thermal treatment may lead to nutrients losses. Previous studies showed that the enzyme activity in wheat germ can be effectively inhibited by fluidized-bed drying, thus prevented fatty acid rancidity and extended wheat germ shelf life.

Due to large amount of unsaturated fatty acid and the presence of highly activated lipolytic enzymes, including lipase (LA) and lipoxygenase (LOX), WG products can easily turn into rancid flavor and shorten its short shelf-life. In the fluidized-bed drying process, the solid particles behave like a fluid due to air blowing and vigorously mix with the uniform and hot drying air. As a result, the drying time is shortened due to intensive heat and mass transf

Abstract:

The drying characteristics for different crops (grains and vegetables) are analyzed using a fluidized bed dryer with respect to the moisture content, diffusivity and physical properties of grains and vegetables. Temperature dependence of mass transfer coefficients is established in terms of Arrhenius type of relation. Drying constant and shrinkage constant of different shaped samples are also studied. Simple mathematical expressions are developed relating volumetric shrinkage constant with drying constant. Dimensionless groups viz. Reynolds number, Schmidt number, and Sherwood number are deter

Abstract:

碩士<br>長庚大學<br>化工與材料工程研究所<br>97<br>A countercurrent continuous fluidized bed system performs different flow regimes at different operating conditions. This thesis focused on the investigation of the effect of the hole arrangement on the plate on the bed flow regimes and the application of this system to porous particles drying. The results showed that with the same plate hole opening ratio、different plate hole arrangement affected the particles flow regimes. The triangular hole arrangement required higher gas velocities and/or solid feeding rates to reach the same stable flow regimes when compa

Abstract:

Attempts have been made to study the drying characteristics for different grains and vegetables by carrying out experiments in a fluidized bed dryer. Drying characteristics have been analysed in terms of moisture content and diffusivity for grains and vegetables dried through the laboratory scale fluidized bed dryer. Characteristic drying curves have been plotted. The effects of different system parameters (viz. temperature, time, and density of material and fluid velocity) on the drying performance i.e. on moisture content and diffusivity of the sample have been studied in the present work.
