Extruder for making self-heating rice

Abstract

The invention provides an extruder for making self-heating rice. The extruder comprises a base, a motor arranged in the base, a screw in power connection with the motor and an extrusion cavity sleeving the screw, wherein an extrusion die head communicated with the extrusion cavity is arranged at the tail end of the extrusion cavity; the extrusion screw is matched with the extrusion die head to extrude powdery rice grains into rice blanks; a shearing mechanism for shearing the rice blanks into grains is arranged at the extrusion die head; a protective cover is also arranged at the extrusion die head; the protective cover covers the extrusion die head and the shearing mechanism; at least two discharge channels are formed in the lower part of the protective cover; the discharge channels are formed below an extrusion opening of the extrusion die head; a baffle for opening and closing upper openings of the discharge channels is arranged in the protective cover; the baffle rotates in a vertical plane; and lower openings of the discharge channels are open. The rice grains extruded by the extruder are smoothly discharged and are difficult to adhere, good rice and bad rice can be timely distinguished and discharged without disorder, and the discharged rice grains are compact, complete and full.

Description

technical field [0001] The invention relates to the field of food processing equipment, in particular to an extruder for making self-heating rice. Background technique [0002] With the quickening pace of life, the consumption of convenience food is increasing, especially instant rice. [0003] The existing instant rice on the market mainly includes: dehydrated and dried type, low-temperature frozen type, canned type, etc. The above several types of instant rice are not suitable for instant brewing. For example, the dehydrated and dry type is affected by the addition of water by the customer. If there is too much water, the rice will be too soft, and if there is little water, it will be hard, and the taste cannot be controlled; although CN101273768 is disclosed The preparation method and craft of frozen type instant rice have been disclosed, but because the transportation cost of frozen type instant rice is relatively high, reheating needs a microwave oven, and it is still ...

AI Technical Summary

Problems solved by technology

However, although a protective cover is added, in the process of cutting and granulating, because the extruder needs to heat the rice germ in the process of extruding the rice germ, so that the rice germ needs to be matured during the molding process, so the temperature of the cut rice grain is relatively high. , and sticky, it is easy to stick into a group after cutting and put it directly into the receiving box, which is not conducive to forming individual rice grains

And in the production process, if there is sticky rice or unqualified rice, it cannot be processed, so it can only be shut down, and then manually go to the collection container to select one by one
