The Application of Vibrating Screen in Food Industry

Vibrating screen is a highly efficient screening machinery used in food industry. It’s mainly used for high precision fine powder and other materials with its advantage of easy operation and fully enclosed structure.

It is also suitable for granular, powder, mucus and other materials screening and filtering classification，Such as powdered sugar, starch, salt, rice flour, milk powder, milk, egg, soy sauce, vinegar, fruit juice, papaya powder, green tea powder, kudzu powder, and potato processing production. Materials mentioned above are used frequently in daily life, vibrating screen will be our best assistant.

Take Starch or rice powder for example, In the first step, we usually remove the impurity of raw materials followed by screening and weighing; The next step includes soaking, coarse grinding, germ separation, fine grinding, screening of starch, protein separation, centrifugal dewatering and thermostatic drying, The last step includes weighing and product packing.

During these steps, we will have great difficulty in processing the food without the screening of vibrating screen. Vibrating screen has the superiority in easily screening fine material, and therefore bring us the food diversification and help to develop the entire food industry rapidly.

True Or False Vibrating Screen

With the rapid growth of economy, vibrating screener market is becoming more and more important, meanwhile, more vibrating screen manufactures emerge as the times require. The products’ quality are uneven of different manufactures. Vibrating screener with superior quality is perfect in workmanship, plate standard and no welding seam blind angle welding seam, etc. There are some of merchants sell seconds at best quality prices who sacrifice customers’ interests for their own benefits.

As far as vibrating screen is concerned, it mainly consists of carbon steel, stainless steel 304 and stainless steel 316L. The carbon steel vibrating screen is appropriate for non-corrosive materials, while stainless steel 304 is commonly used in chemical, food, pharmaceutical industry, etc. The stainless steel 316L is applied in special industry which required for high standard with high cost.

Vibrating screen can be judged through the texture of screen machine. The surface of 304 stainless steel is smooth, toughness, high plasticity, and mechanical strength. But the vibrating screen with poor quality presents unqualified welding, easy oxidation, and thus cut down the overall quality. Therefore, the users must choose formal manufacturers through careful identification .

In addition, Users are supposed to get ready for the products inspection selecting products with high quality, safety performance, and great strength. Taking the price of the products into consideration. After all, “Different quality ,different price.” Never chose the inferior products for cheap price.

Application of Dewatering Screen in Beneficiation Process of Potash Feldspar

Recently, most of manufacturers choose spiral classifier and pressure filter to dehydrate potash feldspar during dehydration process. But there are some disadvantages, spiral classifier cannot classify materials completely and pressure filter needs large investment. What’s more, if users adopt spiral classifier to deal with the separation of residue water during the production of potash feldspar, it will cause the finished materials containing too much water so that the materials cannot be dry heaping. It is found that if users adopt dewatering screen instead of spiral classifier, the water content of potash feldspar will be less than 15% after dewatering by dewatering screen and the materials can achieve dry heaping effect. Furthermore, it can increase recovery rate of finished products because the dewatering screen can elect fine sand which will lose caused by spiral classifier.

 

There are two applications for dewatering screen used in beneficiation process of potash feldspar, one is used for classification of potash feldspar which is processed by ball mill, another is used for dewatering of potash feldspar products. In the traditional production process, it always uses pressure filter to deal with this kind of materials during the dewatering process of potash feldspar products. But this kind of production technical has large energy consumption, lower working efficiency and higher water content. While if users adopt dewatering screen to deal with potash feldspar, it can improve the production efficiency greatly, also can reduce energy consumption and floor space.
