I-grade and II-grade curing extruder suitable for non-fried side crop instant noodles

Abstract

The invention relates to an I-grade and II-grade curing extruder applicable to non-fried side crop instant noodles. The I-grade and II-grade curing extruder comprises an I-grade extrusion sleeve (1), an II-grade extrusion sleeve (14), a cooler (7) and a heater (15), wherein the outer part of the I-grade extrusion sleeve (1) is sleeved with an I-grade circulating water jacket (4), and the interior of the I-grade extrusion sleeve (1) is coaxially sleeved with an I-grade extrusion screw rod (3); the outer part of the II-grade extrusion sleeve (14) is sleeved with an II-grade circulating water jacket (12); an extrusion die plate (11) is fixedly arranged at the discharge end of the II-grade extrusion sleeve (14) by a fixed sleeve (10) by virtue of a thread, and two stop dogs are also arranged on the extrusion die plate (11); and the interior of the II-grade extrusion sleeve (14) is coaxially sleeved with an II-grade extrusion screw rod (13).The I-grade and II-grade curing extruder suitable for the non-fried side crop instant noodles, disclosed by the invention, has the advantages such as compact structure, good curing effect, regular flour belt edge and convenience in operation.

Description

technical field [0001] The invention relates to the field of food processing machinery, in particular to a stage I and stage II ripening extruder suitable for non-fried miscellaneous grain instant noodles. Background technique [0002] Because miscellaneous grains are different from wheat and have gluten structure, the processing of miscellaneous grain instant noodles cannot adopt the traditional noodle rolling process, but the protein in miscellaneous grains is denatured to form noodles through the extrusion of an extruder. During the pressurization process, the pressure and temperature of the extruder must be controlled to fully ripen the miscellaneous grains while avoiding their puffing. For this reason, a two-stage extrusion device is usually used. The first stage fully matures the raw materials, and the second stage is controlled so that the noodles are shaped without puffing. In the traditional two-stage extrusion device, the temperature inside the extrusion device is...

AI Technical Summary

Problems solved by technology

In the traditional two-stage extrusion device, the temperature inside the extrusion device is determined by experience. The material is directly pushed to the extrusion die plate by the extrusion screw for extrusion. There is a certain degree of inhomogeneity in the curing process, and the existing mold During the processing, the edges of the noodles formed by the noodles extruded from the thread hole are scattered, which leads to the unqualified size of the processed noodle cakes, which affects the processing efficiency.
