I. Overview
A heated fluidized bed dryer is digesting the latest technology and the development of domestic and foreign products, the use of the pipe fluidized drying technology, which is developed in a conventional fluidized bed drying and indirect heated on a dry basis new drying technology that will tubular heat exchanger immersed in the fluidized-dried material, no material required for dehydration heat pipe heat exchanger and are supplied by the flow of the heating medium used.
Second, the principle
Sub-machine drying and cooling sections, drying section drying medium (hot air) into the hot air chamber from the hot line, but also by the distribution plate into the flow of the box, while the flow of the heater inside the box to make it through the steam heating . Within the material continuously fed from the feed port dryer, hot air when the wind speed reaches flow velocity, the material is formed in the fluidized bed, and between the hot air heater and heat transfer and mass transfer, and dried to obtain a homogeneous material. Cooling section of the cooling medium into the pipeline from the cold cold room, through the distribution plate into the flow of the box, while cooler through the cooling water, the material from the drying section enters the cooling section, after the cold wind and cooler, is discharged from the discharge port .
Three characteristics
1, in the flow of heat conduction heater box set, cleverly combines convection and conduction heating, thermal efficiency is improved.
2, compact machine, in the same capacity, the footprint of only 50% of hot air heated fluidized bed.
3, fluid bed ventilation plate using a special form of structure, seamless material phenomena.
4, with adjustable overflow plate, the discharged amount and the residence time of the material in the machine can be flexibly adjusted.
5, can achieve drying, cooling integration.

Fourth, the scope
It applies to particles, dried powdered materials, used in food, chemical and other industries, especially for refined salt dry.
