Domestic disk type drier is introduced, researched and manufactured by Shanghai institute of Chemical Equipment firstly. The improved coiled drier by our company should be at the same technical level compared with abroad same kind product and belongs to the third generation product. Our company is one of domestic special enterprises.

Wet materials are fed continuously to the first drying layer on the top of the dryer. They will be turned and stirred by rakes when the rake arm rotates and flow through the surface of the drying plate along the exponential helical line. On the small drying plate they will be moved to its outer and drop down to the outer edge of the large drying plate underneath, and will be moved inward and drop down from its central hole to the small drying plate on the next layer. Both small and large drying plates are arranged alternately so as materials can go through the whole dryer continuously. The heating media, which could be in forms of saturated steam, hot water or heat conducting oil will be led into hollow drying plates from one end to the other end of the dryer. The dried materials will drop from the last dryer of the drying plate to the bottom layer of the shell body, and will be moved by rakes to the discharge port. The moisture escapes from materials and will be removed from the moist discharge port on the top cover, or sucked out by the vacuum pump on the top cover for vacuum-type plate dryer. In vacuum plate dryer, wet air be drawed out by the vacuum that be quipped on the top-cover. The dried materials discharged from the bottom layer can be packed directly. The drying capability can be raised up if equipped with supplementary devices such as finned heater, condenser for solvent retrieval, bag dust remover, return and mix mechanism for dried materials and drawing fan etc. Solvent in those dried paste and heat sensitive materials can be easily retrieved, and thermal decomposition and reaction can be carried out.
It is operated at condition of seal, and simple in operation, high efficiency, save energy (1.3~1.6 kg steam/kg/H2O) . operation time is adjustable (15~60min) and it has wild application.
