Production process of whole wheat flour prepared by stone mill

Abstract

The invention discloses a production technology of whole wheat flour by using a stone mill. The production technology is characterized in that wheat grains are fed by a feeding hopper, and are conveyed to an air separator through an oblique shaftless screw conveyor and impurities like shells and straw are removed, then the wheat grains enter a cylinder cleaning sieve for cleaning, the cleaned wheat grains are mixed with water uniformly through a dampening auger, and then a mixture is conveyed a stock bin for wheat wetting temporary storage; and the wetted wheat grains are conveyed to a wheat brushing machine for wheat brushing treatment, then the wheat grains after the wheat brushing treatment are conveyed to a steel flour mill for precrushing treatment twice, then the wheat grains after the precrushing treatment are conveyed into a cyclone unloader and are unloaded to a first minor sifter for classification sifting, a part of front extraction powder is obtained, the rest material is conveyed to the stone mill to be further milled, the material milled by the stone mill is unloaded to a second minor sifter through the cyclone unloader for sifting, and finished whole wheat flour is obtained. The production technology has the advantages that the advantages of a large flour milling technology and the existing stone mill milling technology are integrated, the material is conveyed by pneumatic conveying and the oblique shaftless screw conveyor throughout, the production technology is flexible, the structure is simple, and the design is reasonable.

Description

technical field [0001] The invention relates to a production process of whole wheat flour, in particular to a production process of whole wheat flour prepared by stone milling. Background technique [0002] Whole-wheat flour is the whole-grain wheat that is only ground when it is milled, without the need to go through the process of removing the bran. There are a lot of vitamins, minerals, and cellulose in wheat germ. In addition to these good vitamins contained in the bran, wheat germ is also rich in vitamin E, which can prevent the decline of physiological functions. Whole wheat flour has the original wheat flavor of wheat, and the bran part contains vitamins B1, B2, B6, pantothenic acid, vitamins, phosphorus, calcium, iron and other small amounts of minerals and trace elements that are beneficial to the human body. Stone-milled whole-wheat flour refers to whole-wheat flour made by stone milling. The stone mill consists of an upper millstone, a lower millstone and a millb...

Problems solved by technology

[0003] The existing stone-milled whole-wheat flour processing technology generally uses a single stone mill for grinding, and then sieves and classifies to obtain finished flour, which is inefficient and labor-intensive. Some enterprises use stone mills in the existing milling process, and the processing cost is high. , strong maintenance
