Problems solved by technology

In the existing technology, in order to reduce the energy consumption of mechanical energy, some manufacturers will add steam to the material at the end of the feeding, because the addition of steam can improve the degree of gelatinization of the material and reduce the mechanical energy required in the process of material gelatinization, but its magnitude limited
Because: the space of the puffing chamber is very small, the residence time of the material in the whole puffing chamber is very short, and the time for the steam to permeate the material is very short, so the degree of maturation of the material due to the effect of steam becomes relatively limited

Abstract

The invention discloses a puffing processing device of bypass curing and a puffing processing method thereof in processing field of grain and feed. The device comprises an extrusion chamber in which an extrusion rod is arranged; an extrusion screw is provided with a material stopping ring matching with the extrusion chamber; the material stopping ring divides the extrusion chamber into a primary extrusion chamber and a secondary extrusion chamber; a bypass pipeline is arranged between the primary extrusion chamber and the secondary extrusion chamber to communicate the primary extrusion chamber and the secondary extrusion chamber; and a steam heating chamber is arranged outside the bypass pipeline. The puffing processing method is mainly characterized in that the material enters the bypass pipeline after being extruded in the primary extrusion chamber, the material is heated and cured in the bypass pipeline and then is extruded after entering the secondary extrusion chamber, and finally the material is discharged, cut and molded. The device and the method save mechanical energy and reduce abrasion and can be used for puffing processing of materials of grain and feed.

Description

Technical field [0001] The present invention mainly relates to forming equipment and technology in the field of food, food and feed processing, in particular to an extrusion processing device and an expansion processing method. Background technique [0002] The existing processing device for food and feed extrusion and puffing includes an extrusion cavity, an extrusion screw is arranged in the extrusion cavity, one end of the extrusion cavity is provided with a feed inlet, and the other end is provided with a discharge cutting device. When working, the extrusion screw continuously pushes the material from the inlet to the discharge cutting device, and the material is expanded and cut into shape. In this process, the material has gone through several stages such as feeding, kneading, and final maturation. The pressure of the material gradually increases, and the temperature gradually rises. Under the conditions of high temperature, high pressure, and high shear, the physical prope...
