preparation example Construction

[0021] The present invention provides a kind of preparation method of puffed soybean for feed on the one hand, and this method comprises the following steps:

[0022] (1) pulverizing the soybean raw material after removing iron and impurities;

[0023] (2) sending the pulverized soybean material obtained in step (1) into a microwave puffing machine for microwave puffing;

[0024] (3) The soybean raw material after the microwave puffing that step (2) obtains is directly imported in the insulation tank and stirred and kept warm, and the holding time is 90-120min;

[0025] (4) Take out the puffed soybean after step (3) heat preservation, cool and pulverize.

[0026] In the present invention, in the step (1), the equipment for the iron removal operation can be conventionally selected in the field. Preferably, the iron removal is carried out in a magnetic rolling barrel.

[0027] In the present invention, in step (1), the equipment for the impurity removal operation can be conve...

Embodiment 1

[0040] (1) The soybean raw material after removing iron and impurities is crushed to an average particle size of 3 mm, wherein the operation of iron removal is carried out in a rolling magnetic bucket, and the operation of removing impurities is carried out in a vibrating sieve;

[0041] (2) Send the crushed soybean material obtained in step (1) into a microwave puffing machine for microwave puffing. The absolute pressure of microwave puffing is 0.55MPa, the temperature of microwave puffing is 85°C, and the power of microwave puffing is 550W. The puffing time is 70s;

[0042] (3) The soybean raw material after the microwave puffing that step (2) obtains is directly imported in the heat preservation tank and stirred and kept warm, and the heat preservation time is 120min;

[0043] (4) Taking out the extruded soybean after heat preservation in step (3), cooling and pulverizing to obtain the extruded soybean A1 for feed.

Embodiment 2

[0045] (1) Grinding the soybean raw material after removing iron and impurities to an average particle size of 4mm, wherein the operation of iron removal is carried out in a rolling magnetic barrel, and the operation of removing impurities is carried out in a vibrating sieve;

[0046] (2) Send the crushed soybean material obtained in step (1) into a microwave puffing machine for microwave puffing. The absolute pressure of microwave puffing is 0.7MPa, the temperature of microwave puffing is 95°C, and the power of microwave puffing is 650W. The puffing time is 60s;

[0047] (3) The soybean raw material after the microwave puffing that step (2) obtains is directly imported in the heat preservation tank and stirred and kept warm, and the heat preservation time is 90min;

[0048] (4) Taking out the extruded soybean after heat preservation in step (3), cooling and pulverizing to obtain the extruded soybean A2 for feed.

Abstract

The invention relates to the technical field of feed processing, and discloses puffed soybeans for feed and a preparation method of the puffed soybeans. The method comprises the following steps: (1) crushing a soybean raw material subjected to iron and impurity removal; (2) feeding the crushed soybean raw material obtained in the step (1) into a microwave bulking machine for microwave bulking; (3) directly introducing the microwave-puffed soybean raw material obtained in the step (2) into a heat preservation tank, stirring and preserving heat, wherein the heat preservation time is 90-120 minutes; and (4) taking out the extruded soybeans subjected to heat preservation in the step (3), cooling and crushing. According to the method, a microwave puffing technology is adopted, heat preservation is carried out after puffing, the content of antinutritional factors in the puffed soybeans is reduced, the technological process is simple, and the production cost is low.

Description

technical field [0001] The invention relates to the technical field of feed processing, in particular to puffed soybeans for feed and a preparation method thereof. Background technique [0002] In the feed processing industry, soybeans are rich in protein and lipid and have high nutritional value. The protein content is 2 times that of pork and 2.5 times that of eggs. The protein content is not only high, but also of good quality. However, the anti-nutritional factors contained in soybeans: trypsin inhibitor, glycinin and β-conglycinin, etc., can easily cause intestinal diseases in young animals, cause diarrhea, poor growth performance and other problems, and it is difficult to add a large amount in the feed Therefore, it is necessary to process soybeans to remove their anti-nutritional factors as much as possible in order to be more widely used. The extruding process can reduce the content of anti-nutritional factors in soybeans. At present, extrusion and puffing are mostl...
