Embodiment 1

[0025] A method for preparing peeled and expanded full-fat soybean meal that can replace fish meal, comprising the following steps:

[0026] (1) Imported soybeans are selected to remove impurities; the overall temperature is uniformly raised in the drying tower, and the drying time is 40 minutes, the drying temperature is 65°C, and the air inlet temperature is 130°C; after that, the soybean hulls are removed by peeling and winnowing. After passing through the sheller, soybeans are broken into 2 to 4 cloves, and the separation rate of bean cloves and bean skins is ≥95%; the whole bean rate after crushing is less than 5%; the powder degree is less than 5%. After winnowing, Douban contains less than 1% of separated bean skin.

[0027] (2) The soybeans were further crushed into soybean powder, and tempered with 80°C steam, and the tempering time was controlled to be 25s by controlling the feeding speed. Sampling test shows that the moisture content of soybean flour is 22.21%, and...

Embodiment 2

[0030] A method for preparing peeled and expanded full-fat soybean meal that can replace fish meal, comprising the following steps:

[0031] (1) Imported soybeans are selected to remove impurities; the overall temperature is uniformly raised in the drying tower, and the drying treatment time is 60 minutes, the drying temperature is 55°C, and the inlet air temperature is 110°C; after that, the soybean hulls are removed by peeling and winnowing. After passing through the sheller, soybeans are broken into 2 to 4 cloves, and the separation rate of bean cloves and bean skins is ≥95%; the whole bean rate after crushing is less than 5%; the powder degree is less than 5%. After winnowing, Douban contains less than 1% of separated bean skin.

[0032] (2) The soybeans were further crushed into soybean powder, and tempered with steam at 110°C, and the tempering time was controlled to be 15s by controlling the feeding speed. Sampling test shows that the moisture content of soybean flour ...

Embodiment 3

[0035] A method for preparing peeled and expanded full-fat soybean meal that can replace fish meal, comprising the following steps:

[0036] (1) Imported soybeans are selected to remove impurities; the overall temperature is uniformly raised in the drying tower, and the drying time is 50 minutes, the drying temperature is 50°C, and the air inlet temperature is 120°C; after that, the soybean hulls are removed by peeling and winnowing. After passing through the sheller, soybeans are broken into 2 to 4 cloves, and the separation rate of bean cloves and bean skins is ≥95%; the whole bean rate after crushing is less than 5%; the powder degree is less than 5%. After winnowing, Douban contains less than 1% of separated bean skin.

[0037] (2) The soybeans were further crushed into soybean powder, and tempered with 100°C steam, and the tempering time was controlled to be 20s by controlling the feeding speed. Sampling test shows that the moisture content of soybean flour is 20.10%, an...

Abstract

The present invention discloses a preparation method of peeled and expanded full-fat soybean powder capable of replacing fish meal and belongs to the field of soybean feed processing methods. The preparation method solves problems that demand for fish meal increases gradually and market urgently needs to find alternative products. The preparation method comprises steps of peeling, winnowing, crushing, blending, extruding and puffing, cold air cooling, finished product packaging, etc. The preparation method is used to prepare the peeled and expanded full-fat soybean powder capable of replacingthe fish meal.

Description

technical field [0001] The invention relates to a processing method of soybean feed, in particular to a preparation method of peeled and puffed full-fat soybean meal which can replace fish meal. Background technique [0002] The processing or pretreatment of grains by extrusion technology is to put the raw materials in the cavity of the extruder through high-speed extrusion, friction and rapid shearing, so that the protein is properly denatured, the starch is gelatinized, and at the same time, the enzyme activity and Microorganisms are a processing technology in which materials are decompressed after high-temperature and high-pressure treatment, and some physical and chemical properties of materials are changed by using the instantaneous evaporation of water or the expansion characteristics of the materials themselves. The anti-nutritional factors in soybeans are properly destroyed, and the rapidly volatilized steam can destroy the cell wall and fully expose the nutrients. ...
