Single-screw low-temperature wet-process puffing machine

Abstract

The invention relates to a novel single-screw low-temperature wet-process puffing machine belonging to the field of puffing devices. The novel single-screw low-temperature wet-process puffing machine comprises a rack body and a motor, wherein the top of the rack body is provided with a double-screw feeder; the upper middle part of the rack body is provided with a conditioner connected with the double-screw feeder; the middle of the rack body is provided with a secondary feeder connected with the conditioner through a conditioner outlet tee joint; a low-temperature extrusion puffing device driven by the motor is connected with the secondary feeder; the tail end of the low-temperature extrusion puffing device is connected with an extrusion die device; and the outer side of the extrusion diedevice is also provided with a gap self-regulating cutter device connected with the rack body and an electrical control system. The invention is automatically controlled by a programmable logic controller (PLC) and realizes the production of puffed products, i.e. puffed foods, puffed pet foods, puffed aquatic feeds, puffed livestock and poultry feeds, puffed urea, and the like, under a low-temperature condition.

Description

technical field [0001] The invention relates to the field of puffing devices, in particular, a new type of single-screw low-temperature wet-process puffing that is automatically controlled by PLC to produce puffed food, puffed pet food, puffed aquatic feed, puffed livestock and poultry feed, puffed urea and other puffed products under low temperature conditions. machine. Background technique [0002] At present, in the fields of puffed food, puffed pet food, puffed aquatic products and other feed production fields, wet puffing machines designed with high temperature puffing theory are widely used. During the expansion and extrusion process of this kind of expansion system, a certain pressure of steam or normal temperature water should be passed between the interlayers of the screw sleeve to heat up or cool the material, so as to prevent the temperature from being too low to meet the expansion requirements or the temperature from being too high. Scorching phenomenon. Genera...

AI Technical Summary

Problems solved by technology

It is easy to produce feed pulsation, and the conditioner has a large volume, long conditioning time, high energy consumption, and poor powder permeability

Due to the function of the resistance ring (air plug) and kneading and cutting, the material is repeatedly sheared and reversed kneaded during the extrusion process, causing the gluten network of starch raw materials to be disordered, thus affecting the extensibility and plasticity of starch gluten, and The positioning cutter mechanism needs to adjust the cutter in real time when both the cutter and the mold are worn, otherwise it will cause production problems such as continuous particle cutting, tailing and deformation
