First, the carrier fluidized bed dryer

The carrier spray fluidized bed dryer, also known as the media spray boiling dryer, which is based on spray technology, the principle of fluidization technology designed to be continuous drying paste or paste material. There are air filter, heater, fluidized bed, cyclone separator, bag filter, induced draft fan, the feed pump and chute and other components. Fluidized bed filled with a few millimeters in diameter can be fluidized inert carrier (mostly glass beads or ceramic beads), it is also known as inert carrier fluidized bed dryer.

Second, the paddle-type dryer

Paddle-type dryer is a heat transfer-based horizontal mixing dryer. Due to the mixing blade shape oars, solid-called paddle dryer, also known as trough dryer or stirring dryer. Foreign blade dryer has been developed for many years, the current model to Japan's Nara Machinery Co., Ltd. as the representative, has developed a two-axis and 4-axis two structures, more than 10 specifications of the series.

Third, the cyclone dryer

Whirlwind dryer by the German company Hoechst (Hoechst) first developed successfully, its unique principle, to correct the air dryer and fluidized bed dryer deficiencies.

5, rotating flash dryer

In order to solve the chemical industry in the high-viscosity paste-like material drying problem, in 1970 successfully developed a rotary flash dryer. However, "70" type rotary flash dryer has many shortcomings, mainly easy to enter the high-temperature powder area, resulting in material overheating condensation, rotating parts of the mechanical stability is poor. In 1978, the "70" type was reformed, while the "78" type had great progress, but there were some disadvantages, such as instability of powder bed, outlet temperature and residual moisture of products. Now we see the basic structure is after two major structural improvements after the model, called "83" type. Flash dryer as a new model, there are other dryers can not be compared with the advantages. It appears to have aroused the interest of the major chemical companies, rotating flash dryer is currently represented by the Danish company An Haidano, now has more than 70 devices in more than 10 countries, the application of large companies.
