Abstract

The invention relates to a high-efficiency physical peeling method for soybean grains, belonging to the field of feed processing. The method comprises the following operation steps: selecting non-mildew soybeans, drying them in the sun, threshing them, and sieving to remove soil, gravel and impurities to obtain clean soybean grains; superheated steam treatment; two-stage ultrasonic treatment; ultrasonically treated soybeans The grains are placed in the vacuum chamber of the drum; among them, the rotating speed of the drum is 30-40r / min, the heating temperature is 80-90°C; when the vacuum degree is 0.008MPa and normal pressure respectively, the cycle is carried out at a time ratio of 20-30s:5-10s , the cycle is 20 to 30 times; stop the operation, open the vacuum chamber, and take out the soybean seeds. Compared with the prior art, the present invention has the following advantages: good peeling effect, high peeling efficiency, 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 physical peeling method for soybean grains, belonging to the technical field of feed processing. Background technique [0002] Soybean is the world's most important oil crop and high-protein grain-forage crop. The soybean industry has three attributes of economy, politics and society at the same time, and it has important strategic significance for a country's food security, economic growth and social stability. Zeng Xueming. Research on Strategic Planning of my country's Soybean Industry Development [J]. China Agricultural Resources and Regional Planning, 2017,38(09):89-97). my country is the birthplace of soybeans, with a history of more than 4,700 years of cultivation and consumption. [0003] Soybean hulls account for 5% to 8% of soybeans, the main component is cellulose substances, and the fat content generally does not exceed 0.7% (Zhang Haisheng. The nutritional value and efficacy of soybeans[J]. Soybea...
