Extrusion type expansion machine and extrusion die used for same

Abstract

The invention discloses an extrusion type expansion machine and an extrusion die used for the same, which are especially used for forming drawn proteins from materials with high temperature meal as a main material. The extrusion die comprises a collecting cavity (1), a recombination cavity (2), a compression cavity (3) and a discharge nozzle (5), wherein the collecting cavity is used for receiving materials from a screw extrusion device and transporting the materials to a rear material channel; the recombination cavity is used for forming a channel with a constant pore diameter to ensure the materials to be released under uniform pressure; the compression cavity is used for forming a channel with a pore diameter smaller than that of the channel in the recombination cavity to ensure the materials to be extruded and drawn under greater pressure; and the discharge nozzle is used for forming a channel with a pore diameter smaller than that of the channel in the compression cavity to ensure the materials to be extruded to form silk. According to the invention, the drawn proteins with good fiber structures can be prepared by adopting the high temperature meal as the main material, thus improving the utilization rate of the high temperature meal and simultaneously reducing the preparation cost of the drawn proteins.

Description

technical field [0001] The invention belongs to the field of food processing machinery, and relates to an extrusion die of an extruding puffing machine for producing silk protein, which is used to cooperate with a screw extrusion device of the extrusion puffing machine to produce silk protein. In particular, it relates to an extrusion die of an extrusion extruder for producing silk protein by using high-temperature dregs, and an extrusion extruder using the extrusion die. Background technique [0002] In recent years, in the case of a serious shortage of animal protein supply, plant protein mainly derived from high-protein plants such as soybeans or peanuts provides an important development direction for improving human dietary structure and providing high-protein nutritious food. When using vegetable protein to manufacture various protein products, such as vegetarian meat and soybean products, it is necessary to first organize the vegetable protein to form textured protein,...

AI Technical Summary

Problems solved by technology

The protein in this kind of high-temperature meal is almost completely denatured and solidified, the nitrogen solubility index decreases, the bulk density increases, and the viscosity is very small after absorbing water. It cannot form fiber filaments through the conventional extrusion puffing process and extrusion puffing machine, so it cannot processed into silk protein

As a result, the use range of a large amount of high-temperature meal is very narrow, for example, it can only be used as feed, resulting in a large amount of waste
