Full-fat extruded soybean production device and production technology

Abstract

The invention discloses a full-fat extruded soybean production device and a production technology. The full-fat extruded soybean production device comprises a bulk bin, an impurity removal working section, a first crusher and a second tee, wherein a material outlet of the second tee is connected with a peel suction device for removing soybean peels, and another material outlet of the second tee is connected with the first crusher; an arch breaking feeding bin is connected with a tempering device; the material outlet end of the tempering device is connected with an extruding machine; the material outlet end of the extruding machine is connected with a cooler; the material outlet end of the cooler is connected with a second crusher; another material outlet of a third tee is connected with the first crusher; the material outlet end of the second crusher is connected with a first rotary vibration grading sieve; the first rotary vibration grading sieve is connected with a first packaging device. The full-fat extruded soybean production device has the advantages that soybeans are firstly broken and then crushed, so that the productivity of the first crusher is increased, the abrasion of a hammer blade is reduced, and the crushing effect is improved; the peel suction device is used for separating soybean peels from soybean halves, so that the quality of a finished extruded soybean product is mainly improved.

Description

technical field [0001] The invention relates to a full-fat puffed soybean production device and a production process using the device, belonging to the technical field of grain and feed processing equipment. Background technique [0002] Soybean is an excellent plant protein resource with balanced nutrition, containing more than 36% crude protein, more than 17% fat, about 10% starch, amino acids, vitamins, lecithin and minerals. However, soybeans contain anti-nutritional factors such as trypsin inhibitor (TI) and antigenic proteins, and direct feeding can easily cause nutritional diarrhea in young animals and damage their intestines, thus limiting the use of soybeans in young animal diets Applications. The soybean is extruded and extruded to eliminate or reduce the anti-nutrient antigen activity and reduce the harm of anti-nutritional substances in soybeans. At the same time, the protein denaturation, starch gelatinization and soybean oil cell rupture in soybeans increase t...

AI Technical Summary

Problems solved by technology

[0004] At present, the following problems exist in the process of full-fat soybean puffing: ①The crushing efficiency before puffing is low

Due to the high content of soybean oil and strong adhesion, the crushing efficiency is not high during the crushing process, and the service life of the hammer is short, resulting in high production costs

② Arching occurs from time to time, which affects the continuity of production and the stability of the quality of puffed full-fat soybeans

③When crushing after puffing, it is difficult for soybean powder to sieve, and it is easy to paste the sieve, the crushing efficiency is low and the particle size distribution of puffed soybeans is uneven

④ The process flexibility of the puffed soybean production line is not enough to take into account the production of different grades of puffed soybeans. For example, how to make puffed full-fat soybeans with a protein content of 36% or higher for full-fat soybeans with a protein content of 34%

⑤The extruded soybean production line is irreversible for the flow of material processing, which increases the labor intensity of employees during the production and processing process
