Description

A water-saving wheat washing machine

technical field

The utility model belongs to the field of wheat flour milling and processing of agricultural products, and relates to a water-saving wheat washing equipment, in particular to a kind of wet cleaning of raw grain wheat before milling to clean away dust, microorganisms, sand and stones in the ventral groove of wheat. Pesticide residues, etc., further reduce ash and sand content, increase flour whiteness, water-saving wheat washing machine.

Background technique

During the process of wheat growth, harvesting, drying, transportation and storage, some dust, sand and some drug residues will adhere to the surface of the wheat and in the ventral groove, and at the same time, a certain amount of moldy grains, insect-eaten grains, germinated grains, and burnt grains will be produced. Grains, etc., seriously affect the quality of wheat. Therefore, in the milling process, the cleaning of raw grain wheat before milling has a significant impact on important indicators such as whiteness, purity, and ash content of processed flour. The water consumption of wheat dry cleaning is small, but the cleaning effect on dust, microorganisms, insect eggs on the surface of wheat, sediment embedded in the ventral groove, side-by-side mud, cinder, and insect-infested wheat grains is not good, and it is difficult to produce high-quality of flour. Wet "washing wheat" can wash off the dust on the surface of wheat, wipe off part of the outer skin during the drying process, and float out shriveled wheat with no edible value and diseased wheat. It also has the functions of removing stones and water.

In the current wet cleaning, after the wheat enters the wheat washing machine, it is only washed once and then discharged, and the equipment used is simple in structure. However, the cleaning time of materials in the equipment is short, the water consumption is large, and the pollution is serious. Therefore, based on the existing wet cleaning technology, the development of a wheat washing equipment that saves water, improves the cleaning effect of wheat, improves the whiteness and flour extraction rate of flour, and has low cleaning cost can reduce the impact on the environment from the source. Pollution, but also significantly reduce the production costs of enterprises.
