Abstract

The invention relates to a high-efficiency peeling method for corn grains based on physics, which belongs to the field of feed processing. The method comprises the following operation steps: selecting corn without mildew, drying, threshing, and sieving to remove soil, gravel and impurities to obtain clean corn kernels; superheated steam treatment; two-stage ultrasonic treatment; The grains are placed in the vacuum chamber of the drum; among them, the rotating speed of the drum is 40-50r / min, and the heating temperature is 60-80°C; when the vacuum degree is 0.01MPa and normal pressure respectively, the cycle is carried out at a time ratio of 30-40s:10-15s , the cycle is 10 to 20 times; stop the operation, open the drying room, and take out the corn kernels. Compared with the prior art, the present invention has the following advantages: good peeling effect, high peeling efficiency, complete preservation of corn kernels, energy saving and environmental protection, clean and hygienic. The invention has important market and industry value.

Description

technical field [0001] The invention relates to a high-efficiency peeling method for corn grains based on physics, which belongs to the field of feed processing. Background technique [0002] Corn is a high-yielding, nutritious and health-care food resource. Therefore, corn food is regarded as "golden food". According to statistics, about 10% of corn is used to produce starch and alcohol, and 75% is used to produce animal feed ([1] Wang Hongying, Li Niwei, Gao Rui, etc. Effects of different pretreatments on the specific heat of feed corn[J] . Journal of Agricultural Engineering, 2012, 28(14):269-276). Corn not only provides a rich and varied food for humans, but also is one of the most important energy feeds for animals. [0003] The removal of the outer skin of corn kernels is an important link in the process of corn processing, and it is very important in the processing of feed or certain foods ([2] Yang Xiaomei, Da Hongqi. Research on corn peeling and its methods [J]. T...
