Background

Raisins are the famous Chinese Turpan geographical sign products, because Turpan is a famous hot area in China, in the basin, the surrounding of high mountains around the grape is high, the heat is increased rapidly, the heat dissipation is slow, the characteristics of long sunshine, high temperature, large temperature difference between day and night, less precipitation and strong wind power are formed, and the Turpan dry fruits are the only dry fruit products which can be naturally dried in a short time in the world just in the unique arid desert climate of the warm area. Although the drying is rapid, the severe natural environment and the too rapid natural drying mode also cause the raisins to form too many folds in the dehydration process, a large amount of sand grains and soil particles with the diameter larger than 0.1mm exist in the folds, and a thin soil film layer with the diameter smaller than 0.1mm is formed on the surface. Because the raisins are characterized by containing more sugar and being slightly moist, the impurities can be firmly fixed on the surfaces of the raisins due to moisture absorption of the sugar, and particularly, sand grains in the folds are very difficult to clean. At present, a great part of raisins are not cleaned and directly enter manufacturers, the manufacturers can only clean themselves in order to meet the requirements of downstream high-end markets, the cleaning mode is manual cleaning and mechanical cleaning, but the production efficiency is not high, and the secondary pollution is easily caused. At present, most of factories adopt a cleaning mode of a horizontal rotary cylinder body, which has great defects that firstly, raisins form material accumulation on the rotary cylinder body and are fed forwards by the rotation of the cylinder body, the skins of the raisins are easy to be damaged by friction, meanwhile, the raisins cannot be cleaned when the materials are too thick due to unidirectional spraying on the accumulated materials, further, in order to ensure that meshes of sprayed water leaking out are easy to block holes due to impurities such as grape skins, grape stalks and the like, so that the surfaces of the raisins are stuck with other grape skins and fine sand particles which cannot be detected (particularly, the raisins are stained with fine sand after the skins are broken by friction and cannot be cleaned), the raisins can be used within a period of time after production, the grapes are not cleaned completely, secondary pollution is very serious, and oil leakage and product pollution are easy to cause due to the fact that a bearing driving the rotary cylinder body is arranged above a feeding plate and a discharging plate, meanwhile, due to the influence of water flow of water spraying, the bearing is easy to enter water and becomes invalid, the bearing needs to be frequently replaced, the labor and the time are wasted, secondary pollution can be caused to products, and the problem that the bearing is easy to decompose or settle when meeting water like sheep manure and feathers cannot be solved.
