Example Embodiment

[0009] The invention discloses a method for puffing and detoxifying cottonseed meal, comprising the following steps: 1) mixing, adding water and detoxifying agent to cottonseed meal with a shell content of 8-12%, and mixing them uniformly to make The moisture content of cottonseed meal is 20-40%, and the amount of detoxifier added is 15g / kg of urea and 5g / kg of ferrous sulfate; 2) Expansion, the expansion temperature is 120-130℃, and the screw speed is 180r / min Under the same conditions, the cottonseed meal is subjected to high temperature, high pressure and high shear force in the extrusion cavity of the extruder, and physical and chemical changes such as mixing, gluing, gelatinization, and organizational structure occur. It loses its activity under the action of high pressure, moisture and detoxification agent; 3) Drying, drying the detoxified cottonseed meal material.

Abstract

The invention discloses a cottonseed meal puffing and detoxifying method. The method comprises the following steps: (1) mixing, adding water and a detoxifying agent into cottonseed meal with the shell amount of 8-12 percent, and uniformly mixing, wherein the moisture content of the cottonseed meal is 20-40 percent, and the addition amount of the detoxifying agent refers to 15g/kg of urea and 5g/kg of ferrous sulfate; (2) puffing, wherein the cottonseed meal is subjected to the effects of high temperature, high pressure and high shear force in an extrusion cavity of a puffing machine under the conditions that the puffing temperature is 120-130 DEG C and the rotating speed of a screw rod is 180 revolutions per minute, changes of physical and chemical performances and organization structures during mixing, gluing and gelatinizing are caused, and free gossypol is inactivated under the effects of high temperature, high pressure, moisture and detoxifying agent; and (3) drying, namely performing drying treatment on the detoxified cottonseed meal materials. The method is good in detoxification effect, low in loss of effective nutritional ingredients in the cottonseed meal, high in palatability, low in cost, simple and convenient to operate, high in production efficiency and suitable for industrial application.

Description

technical field [0001] The invention relates to a detoxification method of cottonseed cake, in particular to a puffing detoxification method of cottonseed cake. Background technique [0002] Cottonseed meal is a by-product of cottonseed dehulling and oil removal. Cottonseed meal is rich in protein, and cottonseed protein belongs to bean protein, and its nutritional value is far higher than that of cereal protein. It is an important source of plant protein feed. [0003] However, cottonseed meal contains a toxic component—free gossypol, which can cause chronic toxicity to livestock cells, blood vessels, nerves, liver, kidneys, etc., and also have a significant impact on the reproductive system of monogastric animals and livestock. These factors limit its feeding amount. [0004] In order to overcome the above problems, the cottonseed meal used as feed is often detoxified. Common cottonseed cake detoxification methods in the prior art include chemical detoxification, biolo...
