Preparation method and production device of instant wheat germs

Abstract

The invention discloses a preparation method of instant wheat germs. The preparation method comprises the following steps of S1, screening wheat: removing bad grains and other solid impurities in the wheat; S2, preparing the wheat germs: grinding the screened wheat, and collecting flaky wheat germs; S3, extracting the wheat germs: screening the collected wheat germs, and collecting the wheat germs after winnowing and thickness selection; S4, degreasing the wheat germs: degreasing the germs by a subcritical low-temperature extraction method; and S5, preparing the instant wheat germs: roasting the degreased wheat germs. The preparation method has the advantages that by separating the degreased wheat, the quality and mouth feel are improved; by matching with additives, the instant wheat germs can be eaten by different populations; and by degreasing the germs by the subcritical low-temperature extraction method, the modern requirement of low fat of the populations is met, and the overhigh fat content of the wheat is greatly increased.

Description

technical field [0001] The invention relates to the technical field of wheat germ processing, in particular to a method for preparing instant wheat germ and production equipment thereof. Background technique [0002] Wheat is the general designation of Triticum plants, and the representative species is common wheat (scientific name: Triticum aestivum L.), which is a grass plant and a cereal crop widely planted all over the world. The caryopsis of wheat is one of the staple foods of human beings. After being made into flour, it can be made into bread, steamed buns, biscuits, noodles and other foods. After fermentation, it can be made into beer, alcohol, liquor (such as vodka), or biomass fuel. Wheat is one of the three major grains, almost all of which are used for food. One-sixth of it is used as feed. Mesopotamia is the first area in the world to cultivate wheat, and China is one of the countries that planted wheat earlier in the world; [0003] However, in the preparation...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method for preparing instant wheat germ and its production equipment, which can effectively solve the problems in the preparation of instant wheat germ in the above-mentioned background technology, the process is complex, and the germ is damaged due to the limitations of some regions and operations during the preparation. During the preparation, it is impossible to achieve a product with a balanced taste and quality, so that it is impossible to improve the problem of the age group and the population.
