Fluidized bed drying is a very effective drying method for solid particles. The surface of particles suspended in the air stream is fully exposed to the dry environment, so as to obtain better heat transfer effect and shorten the drying time. By continuously controlling the dry air at the inlet and outlet and fully mixing it with solid particles, the same product temperature and uniform drying effect can be achieved.
      fluidizedbed dryer is widely used in chemical, pharmaceutical, agricultural and forestry products, grain, light industry and other fields, is a large amount of general mechanical products. The vibration fluidized bed dryer industry in China has gone through over 20 years from formation, development to maturity. At present, the conventional vibrating fluidized bed dryer in domestic market and the main vibrated fluidized bed dryer needed in the international market are basically made by our country. This shows that the history of fluidized bed driers imported mainly has ended.  
  At present, the main export products of the vibro fluidized bed dryer in China are vacuum vibrating fluidized bed dryer, vibrating fluidized bed dryer, small and medium grain, food and agroforestry spray granulation dryer. The annual export volume is more than 100, the main export areas are Southeast Asia and other developing countries, and have already opened. The door to the European and American market. At present, the total output of the vibro fluidized bed dryer in China accounts for less than 5% of the domestic vibro fluidized bed dryer. The experts expect that the proportion of the export products in the domestic vibro fluidized bed dryer in the period of "fifteen" will reach more than 10%. Such
       In the international competition, the main competitors of the vibro fluidized bed dryer, air dryer and spray dryer are Denmark, Switzerland, Britain, Germany, the United States and Japan. Compared with the competitors, the advantages of the vibro fluidized bed dryer in China are low price, and the main reason is that the automation control degree, appearance quality, complete set and function combination of the products need to be further improved.   
  In view of this, dryers need breakthroughs to make breakthroughs in many ways. First of all, we should meet the direction of intensive food and pharmaceutical enterprises and develop to the direction of high speed and high production. Secondly, it is necessary to make the downstream food enterprises produce by standardization and systematization. No matter from specifications, parameters and spare parts, all sides of the vibrating fluidized bed dryer are standardized and serialized. Such
     At present, domestic enterprises still dominate the middle and low end products, so the vibration fluidized bed dryer in our country wants to be very high and low with foreign products. In the future, the strength of the technology research and development of our enterprises must be strengthened. While consolidating their own fields, domestic enterprises should move steadily forward towards internationalization.
