Special extrusion die of wire-drawing protein extruder

Abstract

The invention relates to a special extrusion die of a double-screw extruder for producing wire-drawing protein by utilizing high-temperature soybean meal and high-temperature peanut meal, consisting of a flow-collecting cavity, a recombination cavity, a compression cavity, an extrusion cavity and a die orifice; the flow-collecting cavity, the recombination cavity, the compression cavity and the extrusion cavity are respectively provided with a cooling liquid and steam input device. The processing technique process is as follows: adding the high-temperature soybean meal and high-temperature peanut meal into the double-screw extruder according to certain proportion, connecting the special extrusion die at the front end of the double-screw extruder, changing the combination mode of the protein by techniques of high temperature, high pressure, high shearing, forming and the like, leading the protein molecules to be arranged neatly and have codirectional organizational structures, simultaneously carrying out bulking and solidification, and forming fibrous protein which has similar chewing feeling with meat. The wire-drawing protein product has low fat, high protein, tough mouthfeel and no bitter taste, is peeled by hand, has the grains of shredded meat and high tensile strength and can be used as the material for manufacturing various health foods.

Description

Technical field [0001] The invention relates to a special extrusion die for a twin-screw extruder using high-temperature soybean meal and high-temperature peanut meal to produce silk-drawn protein, and belongs to the field of food processing machinery. Background technique [0002] High-temperature soybean meal and high-temperature peanut meal protein denaturation is very difficult, and the NSI value is only about 17%. Therefore, the basic raw materials used to produce drawing protein are low-temperature soybean meal and low-temperature peanut meal. In order to obtain low-temperature soybean meal and low-temperature peanut meal, complicated processes are required. This leads to high production costs and poor oil taste. The invention can process high-temperature soybean meal and high-temperature peanut meal with simple process and low cost into silk-drawn protein, so as to save energy and improve the utilization rate of oil-making by-products. Summary of the invention [0003] The...
