Problems solved by technology

The protein in this kind of high-temperature meal is almost completely denatured and solidified, the nitrogen solubility index is reduced, the bulk density is increased, and the viscosity is very small after absorbing water. Through the conventional extrusion puffing process and extrusion puffing machine, it cannot form fiber filaments, so it cannot be processed. drawn 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

Abstract

The invention discloses a twin screw extrusion device and an extrusion type expansion machine adopting the device. The twin screw extrusion device comprises a mixing and transporting section, a mixing kneading section and an extruding and transporting section in sequence along the material transporting direction, wherein the mixing and transporting section is used for mixing and transporting materials; the mixing kneading section is used for extruding, grinding and kneading the materials; the extruding and transporting section is used for extruding and transporting the materials; the screw pitch of the mixing kneading section decreases gradually or decreases in a gradient manner and is less than that of the mixing and transporting section; and the length-diameter ratio of the mixing kneading section is greater than that of the mixing and transporting section. According to the invention, drawn proteins with good fiber structures can be prepared by adopting high temperature meal as a 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 a twin-screw extruder used for an extruder, in particular to a twin-screw extruder for producing silk protein by using high-temperature dregs, and the twin-screw extruder using the twin-screw extruder Extrusion extruder with screw extrusion device. 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, and then process it into various products according to actual needs. [0003] At present, low-temperature protein raw mater...
