Analysis of energy consumption of fr ozen -dry foods in processing
In the view of production process of t he frozen -dry foods,the energy consumption in the four stages including fore -treatment,freeze,freeze -dr ying and after -packing,is analyzed and calculated in this paper.Among t hese stages the proportion of the energy c onsumption in the process of frozen -drying production is the largest.Then some proposal and measure to reduce the en ergy consumption are advanced.
