Pilot-Plant Test on the Hot Air Drying inPotato Staple Foods

Abstract

in order to develop staple potato products suitable for our country, in this paper, based on the previous research of thin layer drying, used box-type ventilation drying machine to carry out the pilot test of potato, and the tested the quality of dry samples. The research results show that the dry products has better color, no obvious browning and products of starch pasting does not occur, DSC test curvehas cave peak of, the absorbent is 211.67%, the gelatinization degree is 23.27%, dry products have low degree of maturation; When using diesel and coal as fuel, the cost of producing 1t potato dried products is 14417 yuan and 12094 yuan respectively, of which the cost of raw materials accounted for 72.83% and 86.82% respectively. The research of this paper provides the theoretical basis for the production and processing of potato grain.
