Description
技术领域technical field
本发明属于农产品加工之小麦制粉加工领域，涉及一种节水洗麦设备，特别涉及一种制粉前对原粮小麦进行湿法清洗、清洗掉小麦腹沟内的灰尘及微生物、砂石、农药残留等，进一步降低灰分和含砂量，增加面粉白度的节水洗麦机。The invention 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, and cleaning away dust, microorganisms, sandstones and pesticides in the ventral groove of wheat It is a water-saving wheat washing machine that further reduces the ash and sand content and increases the whiteness of flour.
背景技术Background technique
小麦在生长、收割、晾晒、运输及储存过程中会在小麦表面及腹沟内粘附一些灰尘、砂石和一些药物残留，同时会产生一定数量霉变粒、虫蚀粒、发芽粒、烧仓粒等，严重影响了小麦的品质。因而，在制粉工艺中，在入磨前对原粮小麦的清洗对加工后面粉的白度、纯度、灰分等重要指标有着重大的影响。小麦干法清洗用水量小，但对小麦表面的灰尘、微生物、虫卵，嵌在腹沟里的泥沙、并肩泥块、煤渣、虫蚀病害麦粒等清理效果不佳，难以生产高品质的面粉。湿法“洗麦”能洗掉小麦表面的灰尘，在甩干过程中擦掉部分外表皮，漂出无食用价值的瘪麦，病害小麦，同时还有去石和着水作用。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.
当前湿法清洗中，小麦进入洗麦机后仅进行一次水洗即排出，所用设备结构简单。但物料在设备中清洗时间短，耗水量大，污染严重。因而，基于现有湿法清洗技术，开发一种节约用水、同时又可提高小麦清洗效果、提高面粉白度和出粉率、清洗成本低的洗麦设备，可从源头上减少了对环境的污染，同时也显著降低企业的生产成本。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.
