Drum dryer is through a rotating cylinder, to heat conduction method, to be attached to the outer barrel wall of the liquid material or strip material, drying a continuous handling equipment. Drying treatment of liquid by high slot into the drum dryer feeding groove. Drying drum transmission device driver, in accordance with the provisions of the speed of rotation. Material from the film distributing device in the cylinder wall, is formed on the surface of membrane material. Cylinder continuous inlet of heating medium, heating tube, a cylinder wall heat transfer the membrane material moisture vaporization, again through the scraper will reach dry material scraping, the screw conveying and storage tank, for packaging. Evaporate the moisture, depending on their properties through the closed hood, introducing the corresponding processing device; the general water vapor, can be directly cover the top of the exhaust pipe is put into the atmosphere. Widely used in food, chemical, pharmaceutical and other industries, viscous, paste-like material drying production process.

| Drum dryer heat conduction is a rotating drying equipment, wet material in the outer wall of the rolling drum to heat transmission heat, removing water, reach the required moisture content, heat from the inner wall to the outer wall, and then through the membrane material, its high thermal efficiency, continuous operation, it is widely used in the fields of liquid material or strip material drying of paste, and is more suitable for viscous materials.

- High thermal efficiency: cylinder to supply heat, in addition to a small amount of thermal radiation and the cylinder end cap portion of heat loss, most of the heat used for wet gasification, thermal efficiency can be as high as 70~80%.
- The drying rate: the cylinder wall material wet film heat and mass transfer process, from the inside to the outside, the direction, the temperature gradient is larger, so that the material surface to maintain a high evaporation intensity, generally up to 30~70kgH2O/m2.h
- Products: roller heating drying quality is easy to control the temperature in the cylinder wall, and the heat transfer rate remained relatively stable, so that the membrane material in steady heat transfer under the condition of dry, product quality can be guaranteed.
- Wide range of application: use of drum drying the liquid material, must have fluidity, adhesion and thermal stability. Form of the material may be a solution, heterogeneous suspensions, emulsions, sol. On the pulp, textile, celluloid strip material, also can use.
- Single machine production capacity, by the barrel size limit general drum drying area, should not be too large. Single drum drying area, rarely exceeding 12m2. The same specifications of the equipment, the feed liquid handling capacity, but also by the liquid properties, moisture content control, material thickness, roller speed and other factors, changes in the larger, generally in the 50~2000kg/h.
- Heating medium and easy used saturated water vapor pressure in the range of 2~6kgf/com2, 8kgf/cm2, rarely more than. On certain requirements under the low temperature drying of materials, can take the water as the heat medium; the high temperature drying of materials, can also be used to heat or high boiling organic compounds used as heating medium.
