Preparation method of coarse cereal meal replacement powder

Abstract

The invention belongs to the technical field of food processing, and particularly relates to a preparation method of a coarse cereal meal replacement powder. The method comprises the following steps:step 1, raw material cleaning: cleaning raw materials, removing impurities, and carrying out air drying for later use; step 2, raw material stir-frying: stir-frying the raw materials until the raw materials are cooked for later use; and step 3, raw material grinding: adding the raw materials into a coarse cereal meal replacement powder making device, and processing the raw materials into powder. The coarse cereal meal replacement powder making device comprises a bottom plate, a grinding mechanism is fixedly installed on the bottom plate, a sealed channel is installed on the bottom face of thegrinding mechanism, a storage box is installed on the bottom plate, and a discharging pipe is arranged on the side wall of the storage box. According to the coarse cereal grinding device, the distancebetween the friction plate and the side wall of the cavity can be adjusted, the device guarantees that coarse cereals of different particle sizes can be fully ground, the device can guarantee that the friction plate makes direct contact with the coarse cereals in the grinding process, and the grinding effect is improved; and meanwhile, two-way grinding of coarse cereals is achieved, and the device guarantees that the ground coarse cereal powder is in a spherical shape in the microcosmic state.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a method for preparing a coarse grain meal replacement powder. Background technique [0002] Coarse grain meal replacement powder is a kind of comprehensive prepared powder food made from sorghum, barley, sesame and black beans and other miscellaneous grains as raw materials. There are the following problems in the production of the existing multigrain meal replacement powder: (1) the existing multigrain meal replacement powder mixes miscellaneous grains together and grinds them into powder during processing. This processing method will lead to excessive grinding of some miscellaneous grains, destroying its internal nutrients, and the other part of miscellaneous grains will not be fully ground, which will affect the taste when brewing and eating; The internal grease will precipitate and adhere to the surface of the grinding sheet, resulting in the inability o...

Problems solved by technology

[0004] The present invention provides a method for preparing a coarse grain meal replacement powder, and aims to solve the following problems in the production of the current coarse grain meal replacement powder: (1) The existing coarse grain meal replacement powder mixes coarse grains together for grinding during processing; Grind into powder, because different types of miscellaneous grains have different particle sizes, this processing method will cause some miscellaneous grains to be over-grinded, destroying their internal nutrients, and another part of miscellaneous grains cannot be fully ground, which will affect the taste when brewing and eating; ( 2) Since the miscellaneous grains contain oil, the oil inside the miscellaneous grains will precipitate and adhere to the surface of the grinding sheet during the crushing and grinding process, resulting in the inability of the grinding sheet to directly contact the miscellaneous grains, which will adversely affect the grinding effect; (3) The existing coarse grain meal replacement powder can only carry out directional grinding on the coarse grains during processing, resulting in the microscopic state of the milled grain powder in an ellipsoidal shape, which cannot achieve the ideal spherical shape, which affects the taste and melting when brewing and eating Effect
