Heating equipment
The fluidized bed dryer is second only to the spray dryer. It is divided into a fluidized bed dryer with a stirrer at the feeding part and a fluidized bed dryer with internal heat exchange. When the fluidized bed is used to dry the powdery and granular materials that are easy to unite or agglomerate, the fluidization difficulty will occur in the feeding section where the moisture is relatively large. At this time, a stirrer is set in the feeding section to eliminate the problem of agglomeration and achieve normal flow. Into. The latter is a combination of conductive heat transfer and convective heat transfer. When the amount of hot air used in the normal fluidized state is far from meeting the heating equipment heat required for drying, an internal heat exchanger is used to supply part or most of the heat. This mode of operation can significantly save energy. There are many forms of internal heat exchangers. Fluidized beds are also often used for combined drying of secondary and tertiary dryers.

According to an authoritative survey report by a * Japanese brewer, the four stores in Daringang had been in operation for 4 years and had a total passenger flow of 5 million people, of which 3 million were fans. One out of four or five Shanghainese. Yes, we have no reason to doubt the Japanese investigation data for their own commercial interests. On the other hand, the diners in the shop are dazzlingly eating, and doubts seem to be their own psychological problems. "
For domestic users, it is more convenient to choose domestic equipment than imported equipment. In terms of the international market, after China's entry into the WTO, it is more conducive to expanding exports of drying equipment. At present, the main export products of dry heating equipment in China are vacuum drying equipment, vibration drying equipment, small and medium-sized grain, food, and agricultural and forestry special product drying equipment. The annual export volume exceeds 100 units. The main export areas are Southeast Asia and other developing countries. Countries, and has opened the door to European and American markets. At present, China ’s drying equipment exports account for less than 5% of domestically produced drying equipment, and it is estimated that during the “Tenth Five-Year Plan” period, exports will account for more than 10% of the total domestically produced drying equipment.
In international competition, the main competitors of China's drying equipment manufacturers are Denmark, Switzerland, the United Kingdom, Germany, the United States and Japan.
Compared with competitors, China's advantages of drying equipment are low-cost heating equipment, the shortcomings mainly lies in the degree of product automation control, appearance quality, completeness and functional combination needs to be further improved.
Therefore, domestic drying equipment manufacturers should take full advantage of China's accession to the WTO, strengthen technical exchanges with foreign countries, learn from the advantages of foreign advanced drying equipment, and accelerate the improvement of the degree of automation control, appearance quality, and completeness of self-heating equipment in
China. Functional combination, narrowing the gap with foreign products, increasing the trust of our products among users, making our drying equipment dominate not only in the domestic market, but also in foreign markets.
