Complete set of equipment and process for processing degreased corn grits and corn flour by adopting full-dry method

Abstract

The invention discloses a complete set of equipment and process for processing degreased corn grits and corn flour by adopting a full-dry method relating to a novel full-dry method corn processing method. The complete equipment comprises a plurality of bucket elevators, a vibration sieve, a magnetic separator, a low-pressure blower (4), a destoner, two emery roll husking machines, a silo, a double-wind husking polisher, a self-balanced vibrating grading sieve machine, a specific-gravity corn degerminating machine, a milling machine, a plurality of elevators, two cylindrical polishers, a low-pressure blower (18), a suspended sieve, a grading flat sieve, an induced-draft separator and other equipment. Compared with the traditional full-wet method corn processing technology and method, the full-dry method corn processing method disclosed by the invention is characterized in that raw corns are processed into flour under a completely drying condition. The defect that the corn flour processed by adopting the full-wet method corn flour processing technology contains water is overcome, the drying process or drying equipment required in the full-wet method corn flour processing technology for avoiding the high possibilities of deterioration and mildewing of the corns containing water is omitted, the production cost is reduced, the production efficiency is improved, the general yield rate of finished products is increased by 10 percent, and the grease content is reduced by 3 percent.

Description

technical field [0001] The invention belongs to the field of deep processing of agricultural products, in particular to a method for fully dry processing corn flour. Background technique [0002] In China, corn is a high-yield agricultural by-product, most of which are used as industrial raw materials or processed into powder as feed. For a long time, the processing of corn flour has been using all-wet processing technology. That is, the rough corn raw material is transported to the vibrating screen through the bucket elevator for screening, and then the iron impurities are filtered through the magnetic separator; the corn raw material that has been preliminarily sorted enters low-pressure fans and de-stoners and other equipment to remove light impurities and The stone is large and impurity, thus completing the impurity removal process. After the impurity removal, the corn raw material enters into the cylinder silo, double-wind peeling and polishing machine, self-balancing...

AI Technical Summary

Problems solved by technology

In this process, after removing impurities, the raw corn needs to be stirred and moistened with water before it can be dehulled and degerminated, which will inevitably lead to excessive moisture content in the corn flour husk

In order to prevent cornmeal husks from becoming moldy and degraded within an unpredictable period of time due to water content, it is necessary to dry them for effective treatment or add a dryer, thereby increasing production energy consumption and increasing production costs
