Problems solved by technology

[0005] The existing rapeseed processing by-product fermentation treatment technology, whether it is multi-strain fermentation or bacteria-enzyme synergistic fermentation treatment, although the shortcomings of its original state have been improved to a certain extent, the obtained fermented products are less effective than raw materials. The removal of factors and the increase of animal palatability are not ideal enough to meet the nutritional needs of modern industrial feed production or breeding animals

Embodiment 1

[0036] 1) Grinding the dried fermented rapeseed processing by-products, the aperture of the sieve of the grinder is 1.0mm, to obtain the pulverized material;

[0037] 2) Transport the pulverized material into the conditioner of the domestic TPH260 extrusion extruder and fully contact and mix it with saturated steam at a pressure of 0.2 MPa and a temperature of 120°C to obtain the tempered material;

[0038] 3) The tempered material is transported into the expansion cavity of the extruder for extrusion treatment, the frequency of the feeder is 35HZ, and the temperature in the expansion cavity of the extruder is 105°C to obtain the expanded material.

Embodiment 2

[0040] 1) Grinding the dried fermented rapeseed processing by-products, the aperture of the sieve of the grinder is 1.0mm, to obtain the pulverized material;

[0041] 2) Transport the pulverized material into the conditioner of the domestic TPH260 extrusion extruder and fully contact and mix it with saturated steam at a pressure of 0.3 MPa and a temperature of 130°C to obtain the tempered material;

[0042] 3) The tempered material is transported into the expansion chamber of the extruder for extrusion treatment, the frequency of the feeder is 35HZ, and the temperature in the expansion chamber of the extruder is 115°C to obtain the extruded material.

[0043] Detect and record the content of isothiocyanate (ITC) and oxazolidinethione (OZT) in the processed expanded material obtained by rapeseed processing by-product (untreated original state) and embodiment 1 and embodiment 2 respectively , see Table 1 for the specific results.

Abstract

The invention provides a treatment method for fermented rapeseed processing by-products, which can reduce the content of antinutritional factors in the rapeseed processing by-products, improve the feeding quality and improve the animal feeding effect. The treatment method of the fermented rapeseed processing by-products comprises the following steps of 1) crushing the dried fermented rapeseed processing by-products to obtain crushed materials; 2) conveying the crushed materials into a conditioner of a bulking machine, and performing saturated steam conditioning treatment to obtain high-temperature conditioned materials; and 3) conveying the high-temperature conditioned materials into a bulking cavity of the bulking machine, and performing extrusion treatment to obtain bulked materials. According to the method, the fermented rapeseed processing by-products are used as raw materials; after wet puffing treatment, the removal rate of the antinutritional factor-isothiocyanate in the fermented rapeseed processing by-products is 81-84%, and the removal rate of the antinutritional factor-oxazolidine thione is 69-74%; and the nutritional requirements of modern industrial feed production or animal breeding can be better met.

Description

technical field [0001] The invention belongs to the technical field of pre-digestion treatment of feed raw materials, and in particular relates to a treatment method for by-products of fermented rapeseed processing. Background technique [0002] The by-products of rapeseed processing are the by-products of rapeseed oil extraction directly, or after pre-pressing oil and extracting residual oil with organic solvents. It is a kind of abundant and cheap vegetable protein feed raw material. [0003] my country is the largest rapeseed producer in the world, rich in by-products of rapeseed processing, with an annual output of more than 10 million tons. Due to the different varieties and production areas, the contents of nutrients and anti-nutritional factors in the by-products of rapeseed processing are quite different. Rapeseed processing by-products contain 35-41% crude protein. Compared with soybean meal, except for lysine content which is lower than soybean meal, the content o...
