Embodiment 1

[0025] The processing method of the puffed wheat of the present embodiment specifically comprises the following steps:

[0026] (1) Add wheat with an impurity content of 2.58% to a three-layer vibrating sieve for screening. The vibration frequency of the vibrating screen is 300 times / min. The apertures of the sieve holes are 7mm in the upper layer, 2mm in the middle layer, and 1mm in the lower layer. The inclination angle of the screen surface is 20 degrees, the upper layer removes wheat bran and straw with larger impurities, the lower layer removes smaller wheat ash and dust, and the middle layer obtains wheat with an impurity content of 0.24%;

[0027] (2) Add the screened wheat to the specific gravity sieve, the vibration frequency of the specific gravity sieve is 350 times / min, the sieve hole diameter is 2mm, the speed of the suction fan is 1100 times / min, and the inclination angle of the gravity table is 8 degrees to remove the specific gravity. Impurities larger than whe...

Embodiment 2

[0033] (1) Put wheat with an impurity content of 1.83% into a three-layer vibrating sieve for screening. The vibration frequency of the vibrating screen is 400 times / min. The apertures of the sieve holes are 8mm in the upper layer, 3mm in the middle layer, and 1.5mm in the lower layer. The inclination angle of the screen surface is The upper layer removes wheat bran and straw with larger volume of impurities, the lower layer removes smaller volume of wheat ash and dust, and the middle layer obtains wheat with an impurity content of 0.16%;

[0034] (2) Put the screened wheat into the gravity sieve for screening. The vibration frequency of the gravity sieve is 380 times / min, the sieve aperture is 3mm, the speed of the suction fan is 1180 times / min, and the inclination angle of the gravity table is 10 degrees to remove the specific gravity. Impurities larger than wheat, such as stones, etc.;

Embodiment 3

[0040] (1) Add wheat with an impurity content of 3.90% to the three-layer vibrating sieve for screening. The vibration frequency of the vibrating screen is 450 times / min. The apertures of the sieve holes are 9mm in the upper layer, 3mm in the middle layer, and 1.5mm in the lower layer. The inclination angle of the screen surface is The upper layer removes wheat bran and straw with larger volume of impurities, the lower layer removes smaller volume of wheat ash and dust, and the middle layer obtains wheat with an impurity content of 0.27%;

[0041] (2) Add the screened wheat to the gravity sieve, the vibration frequency of the gravity sieve is 380 times / min, the sieve aperture is 3mm, the speed of the suction fan is 1150 times / min, and the inclination angle of the gravity table is 9 degrees to remove the specific gravity. Impurities larger than wheat, such as stones, etc.;

[0042] (3) Add the wheat after specific gravity screening into the permanent magnetic drum, the magnetic...

Abstract

The invention discloses a processing method of puffed wheat, belonging to the technical field of feed processing. The processing method of the puffed wheat comprises the following steps of: screening impurity-contained wheat through a three-layer vibrating screen and a specific-gravity screen; adding the screened wheat to a permanent magnetic pulley for removing the magnetic impurities; brushing and cleaning the wheat through a brushing machine and a water washer in sequence to reduce the content of mycotoxins in the wheat; and drying and puffing the wheat to obtain the puffed wheat. The method is simple, the process setting is reasonable, the requirements on processing equipment and technology are low, and the production efficiency of the puffed wheat can be remarkably improved. No toxic and harmful chemical component is added in the processing method, so that the prepared product is safe and non-toxic; and the content of glucan in the wheat is effectively reduced, and thus the mass requirement of feed processing enterprises on the components of the wheat can be satisfied well. The method not only solves the problems of high mycotoxins content and high viscosity of the wheat and improves the wheat quality, but also increases the dosage of the wheat in the feed processing field, improves the utilization rate of medium-level and low-level wheat, and can effectively restrain resource waste.

Description

technical field [0001] The invention relates to a wheat processing method, in particular to a processing method of puffed wheat for feed, and belongs to the technical field of feed processing. Background technique [0002] As an energy raw material, wheat has been widely used in feed rations in Australia, Europe, and Canada. In my country, the output of wheat is second only to corn, becoming the second largest food crop. At present, corn has been widely used in the field of feed processing, and whether wheat can be widely used in feed mainly depends on the ratio between the nutritional value and price of the two. Wheat is rich in nutrients such as starch, protein, fat, minerals, etc. Its protein content (13.5% in wheat, 8.7% in corn) and total phosphorus content (0.41% in wheat, 0.27% in corn) are higher than those in corn. When corn is used as the main raw material for feed processing, it can significantly increase the content of protein and total phosphorus in the formul...
