Drying air temperature

This paper is performed by two experimental methods and Computational Fluid Dynamics. Thermal analysis and calculation are performed on various points on the coil or barrel surface. Correspondingly, the temperature distribution is calculated for the different working modes of the transformer in the case of no-load and rated and short-circuit.

Button mushrooms are highly perishable in nature because of its high moisture content about (85-90%) hence starts deteriorating immediately within a day after harvest. So as to increase its shelf life three different samples of Button Mushroom Slices viz. untreated, blanched and optimized osmosed samples were taken for drying experiment at each level of drying air temperature (50, 60 and 70oC). Drying of osmosed Button Mushroom slices at 70oC drying air temperature provided shortest drying time to produce best quality dried product as compared to blanched and untreated Button Mushroom samples.

This paper aims to quantify the amount of water surface evaporation with special regard to the EWM evaporation pan and to relate the direct measurements to the Penman and other empirical equations. Based on the available 10-minute interval data on the EWM pan evaporation and the data on precipitation for the same intervals, the net water surface evaporation was estimated for the period from July 2010 to October 2012 (excluding the time EWM pan did not function in winter).

The proper drying techniques are the most important aspect for preservation of aroma and colour of basil leaves. The use of solar dryer helps to reduce the moisture content and improves the quality product. Drying treatment and experimental method for solar drying was carried out at the temperatures of 45°C, 55°C and 65°C to find and suggest the optimum drying condition for acquiring quality dried basil leaves and active ingredient like uginol, caryophyll of basil leaves.

Pointed gourd (Trichosanthes dioica) is an important vegetable available seasonally. Pointed gourd slices were dried after pre-treatment using a tray dryer. To accomplish this process, raw, osmosed and blanched slices of pointed gourd were subjected to the drying air temperature of 50, 60 and 70oC in a tray dryer. The drying time of osmosed sample was reduced to 480 minutes as compared to 600 and 840 minutes taken by blanched and raw pointed gourd samples.

Kerala is the region with high humidity and comparatively low solar radiation, there is much scope of uneven and uncontrolled drying of copra. Hence, an attempt was made to develop a sophisticated and advanced forced convection solar dryer. Evacuated tube collector (ETC) was used to generate hot air and used to dry coconuts. It consists of three units: evacuated tube collector, blower and drying chamber. Coconuts (Cocos nucifera) were dried at full load condition in order to evaluate the performance of the developed solar dryer.

The objective of this study was to evaluate the effect of different wall materials and the processing parameters on the microencapsulation of olive oil by spray drying. Casein, maltodextrin and guar gum were used to produce olive microcapsules. Different combination of wall materials (casein/maltodextrin at 1:1 ratio, casein/maltodextrin at 1:2 ratio, maltodextrin/guar gum and casein/maltodextrin/guar gum) and inlet air temperature (140, 160 and 180˚C), for a total of 4 combination of emulsions were prepared.

Drying kinetics of amla- beet root shreds in tray dryer was studied at 55, 65 and 75oC air temperatures. Drying of shreds occurred completely in falling rate period. Four thin layer drying models were fitted to the experimental moisture ratio data. Among the mathematical models investigated, the logarithmic model satisfactorily described the drying behaviour of shreds with high r2 values.

Three different samples of Green Peas with respect to pre-treatments viz. raw, blanched and blanched after pricking were taken for drying experiment. A laboratory model tray dryer was used for drying green peas with different levels of drying air temperatures (50° , 60° , 70°C). The moisture content of green peas decreases an elapsed drying time during tray drying of green peas. The result shows that the blanched green peas had slightly higher moisture content than raw and pricked green peas.
