To improve the drying efficiency, uniformity and germination rate after hot air of Cyperus esculentus seeds, this paper proposed a method that combines tempering drying. The curve was obtained by experiment. influence on quality seeds trend with process parameters (the temperature, moisture content at beginning duration) were analyzed single-factor experiments. regression models established sta...

The drying machine works with the Spray Dryer method to dry particles from a liquid state through continuous spraying in chamber. This uses an atomizer form of 0.2mm mist nozzle type injector capacity 0.00045 kg/s. Function for atomization during process occurs change vortex angle 35°. In this study, used was pure cow’s milk specific heat value 3930 J/kg K. To increase total amount solids, volu...

Multistage heat pump drying of macadamia nut under modified atmosphere was studied to improve the drying process and quality of the nuts. Conditions of study included drying temperature of 40-60°C, using nitrogen and normal air as drying medium. Drying kinetics and quality of nuts (moisture content, aw, rancidity and colour) as well as energy consumption of all drying processes were examined. T...
