Disc continous drier is a kind of efficient conduction type continous drier. Its special structure and working principle decide its advantages such as high thermal efficiency, low energy consumption, small covering area, simple configuration, easy operation and good operation environment. It is widely applied to chemical, medical, pesticide, food, forage and agricultural sideline products. It enjoys good reputation amony various fields. At present, it is divided into three kinds, normal pressure, closeness and vacumm, four types (1200, 1500, 2200 and 3000), A (carbon steel); B (the area which contacts with materials is made from stainless steel); C (based on B, add steam line, main shaft and bracket made from stainless steel; the liners of drum body and cap top are made from stainless steel). There are three material qualities. Drying area is 4 to 180 square meters. There are hundreds of models in this series of equipment. We can also provide matched auxiliary equipment with these models. Customers’ different demands for drying various materials can be met by our products.

Wet materials are sent constantly to the first-layer drying tray which is on the top of drier. Rake arm makes rake blades rotate. Materials are stirred by the rotation of rake blades. Along the exponential screw line, materials flow by the surface of drying tray. Materials on the smaller drying tray are sent to the outer margin and drop to the outer margin of the bigger drying tray. Materials on large drying tray move to the center and drop on the small drying tray of next layer. Small and large drying trays are arranged up and down alternately. Materials can flow by the whole drier. Heating media is sent to a hollow drying tray. Heat media which can be divided into saturated steam, hot water and heat conduction oil. Heating media enter the drier from one end of drying tray and leave from the other end. Materials which have been dried drop the the bottom of shell body from the last-layer drying tray. Finally, materials are sent out to the outlet by rake blades. Moisture escape from materials and is discharged from the moisture outlet set on the top cap. Moisture in vacumm disc drier will be discharged out from the vacumm pump set on the top cap. Materials discharged from the bottom can be directly packed. Production capacity can be increased by adding fin heater, solvent recovery condenser, bag filter, dry material backmixing system and induced draft fan. Solvent in dry paste and thermal sensitive materials can be recycled easily and be pyrolyzed. 

1. Drying tray
A. Designed pressure: generally, the pressure is 0.4 Mpa. The highest pressure can reach to 1.6 Mpa.
B. Highest operation pressure: generally, it is not over 0.4 Mpa. The highest pressure can reach to 1.6 Mpa.
C. Heating media: steam, hot water, heat conducting oil; when the temperature of drying tray is 100 degree centigrage, heat it by hot water; 100 degree centigrade to 150 degree centigrade, use saturated water vapor not over 0.4 Mpa or over hot steam to heat the drying tray; 150 degree centigrade to 320 degree centigrade, use heat conducting oil to heat the tray; over 320 degree centigrade, use electricity, heat conducting oil and fused salt;
2. Material conveying system
A. Rotary speed of main shaft: 1 to 10 r/m, electromagnetic or frequency converison stepless speed regulation;
B. Rake arm: 2 to 8 rake arms fixed on main shaft on each layer;
C. Roll mill: for materials which are easily lumped and needs to be crushed, install as roll mill on proper position. Then, heat transfer and drying process can be strengthened;
3. There are three types of shell body, normal pressure, closeness and vacumm
A. Normal pressure: cylinder and eight prismatic shape; there are two kinds of structure, entirety and split. The inlet and outlet pipeline of heating media can be installed in the shell body or out of the shell body.
B. Closeness: cylinder shell body; can afford 5 Kpa inner pressure; The inlet and outlet pipeline of heating media can be installed in the shell body or out of the shell body.
C. Vacumm: cylinder shell body; designed pressure is 0.1 Mpa; inlet and outlet of heating media are installed in shell body;
4. Air heater
Generally speaking, it is used when evaporation amount is large. It is used to strengthen drying efficiency.
