Description

Grading cleaning wheat washing machine

technical field

The utility model relates to a processing equipment for agricultural products, in particular to a method for wet-washing raw grain wheat before milling to remove mildew, heat change, pesticide residues and other wheat odors, and to clean dust, microorganisms and sand in the ventral groove of wheat. Stone, further reduce the ash and sand content, increase the whiteness of flour graded cleaning wheat washing machine.

Background technique

During the process of wheat growth, harvesting, drying, transportation and storage, a certain amount of moldy kernels, insect-eaten kernels, germinated kernels, burnt kernels, and drug residue contaminated kernels will be produced, which seriously affect the quality of wheat. Therefore, in the milling process of flour processing enterprises, 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. There are two main types of wheat cleaning: dry method and wet method. Due to the small water consumption and low pollution, dry cleaning is mainly used in large-scale milling enterprises in urban areas. However, dry cleaning is harmful to dust, microorganisms, insect eggs on the surface of wheat, silt embedded in the ventral groove, side-by-side mud, The cleaning effect of cinders, insect-eaten wheat grains, etc. is not good, and it is difficult to produce high-quality flour. The wet "washing wheat" can wash off the dust on the surface of the wheat, wipe off part of the outer skin during the drying process, and float out the shriveled wheat with no edible value. More than 80% of the diseased wheat and chemical residue wheat are removed, and the flour extraction rate is improved. It also has the functions of stone removal and water removal.

With the improvement of people's requirements for flour quality, newly-built flour processing enterprises and small and medium-sized flour enterprises in rural areas and suburbs where water and sewage are more convenient have re-used the wheat washing machine and adopted the wet cleaning technology of "washing wheat". . In the current wet cleaning, after the wheat stream enters the wheat washing machine, it is only cleaned once and then discharged. The equipment used in this cleaning method has simple structure and low cost, but the cleaning time of materials in the equipment is short. In order to maintain the cleaning quality, we can only increase the water supply. Therefore, the current water consumption for washing wheat is large, basically a ton of wheat and a ton of water.

Therefore, it is very necessary to design and develop a reasonable structure design, convenient operation, effective cleaning of wheat, improvement of flour whiteness, improvement of flour extraction rate, and low cost graded cleaning wheat washing machine on the basis of the prior art.
