Embodiment 1

[0063] Embodiment one: the preparation of high-protein cotton meal

[0064] See attached figure 1 , the present invention provides a kind of preparation method of high-protein cotton meal, % is calculated by weight ratio w / w (kg / kg), and specific preparation method is as follows:

[0065] (1) Cottonseed delint and impurity removal: After the cottonseed has been processed to remove impurities and delint, the impurity content is less than 0.5%, and the cashmere content is less than 4%.

[0066] (2) Cottonseed peeling: The cleaned and removed cottonseed is evenly fed into the shelling roller through the frequency conversion feeding device, and the tooth angle of the first set of toothed rollers of the shelling roller is 40°-85°. The angle is the angle between the horizontal line and the inclined line, and the adjustment gap is 2.4-2.8mm; the tooth angle of the second set of toothed rollers is 35°-70°, the tooth angle is the angle between the horizontal line and the inclined lin...

Abstract

The invention discloses a preparation method for high protein cottonseed meal and a selected device therefor. The preparation method includes delinting cottonseeds, removing impurities of the cotton seeds, and husking; feeding into a husking roller uniformly by a variable frequency feeding device, putting the mixture of husks and kernels after husking into a cottonseed kernel and husk separation device, putting the fine selected cotton kernel into a double-roller flaking device, then putting into a layered cooker for wetting, steaming, frying to obtain cooked flakes, wherein a medium-temperature medium-wet technology is adopted in the steaming and frying step, so that the protein denaturation is avoided to the greatest extent while the free gossypol content is effectively reduced. Meanwhile a press screw device applicable to the cottonseed kernel and husk separation device and a spiral oil press is provided, so that the cottonseed husking efficiency is high, the prepared high protein cottonseed meal is high in quality, the prepared high protein cottonseed meal has the crude protein content of not less than 52%, the bottom oil of not more than 1.0%, the moisture of not more than 9.0%, the crude fiber of not more than 6.0%, the crude ash of not more than 7.5%, the NSI value of not less than 65% and the free gossypol of not more than 800ppm, and is wide in application and promotion values.

Description

technical field [0001] The invention relates to the technical field of deep processing of oil crops. Specifically, the present invention relates to a method for preparing high-protein cotton meal and the technical field of selecting equipment. Background technique [0002] Cottonseed is an oil plant with high protein and oil content. In recent years, my country's animal husbandry and feed industry have developed very rapidly. Protein is the main raw material for feed and protein raw materials are scarce in my country. At present, the total demand for protein raw materials is 46 million tons, and the supply gap is more than 20 million tons per year, which requires a large amount of imports. [0003] Cottonseed is an oil plant with high protein and oil content. In 2013, the domestic cottonseed output was about 9 million tons, and Xinjiang's output was about 5 million tons. As a cotton-producing area, it ranks first in the country in terms of total output, per unit area yield...
