1. Continuously drying of viscous, pasty and sticky materials in food, chemical and pharmaceutical industry;
2. Heating area: 1.12-21.2 M2
3. Evaporation capacity: 6-150 kg water/hour
4. Feeding type: top or bottom feeding
5. Heat source: steam or hot water
HG series rotary scraper drum dryer is a continuous indirect-heating drying processor. The dryer body consists of rotary drum heated by steam, applicator rollers, scrapper and exhaust hood. Liquid raw meterials are fed onto the rotary drum from the top or from the bottom tray. With the kneading effect of applicator system, raw materials are evenly spread onto the heated surface of rotary drum. Moisture evaporates very quickly. Drying process is done within a single rotation of the drum and the dried product is scrapped off with the knife.
HG series drum dryer with its continuous indirect drying method, allows short heat retention time while evaporating all the liquid within a single rotation of the drum. It not only virtually eliminates the risk of damaging the product but also enables the product to keep its unique properties like taste, smell, texture etc. Drum dryer is unique for drying viscous, pasty and sticky materials in food, chemical and pharmaceutical industries.

1) High heat efficiency: Heat loss is mainly caused thermal radiation. Heat efficiency can be as high as 90%.
2) Short drying time: The drying process only takes 10-15 seconds. So drum dryer can be used for drying heat sensitive material.
3) Uniform drying: Heat transfer direction and coefficient all over the drum surface are the same. And wet material can be evenly spread over the drum surface. Wet material can be uniformly dried.
4) Long life span: Rotary drum is electro-polished and well heat treated to increase the smoothness and hardness.
5) Flexible application: Drum surface temperature, rotating speed, wet material film thickness are all adjustable to satisfy materials with different moisture and drying time.
6) Compact size: The drying chamber is very compact in size. Only need small installation space.
7) Low operation cost: The whole machine is very simple and reliable. It can be used for many years with little repair and maintenance.
8) Highest hygienic standard: Indirect heating and electro-polished drum surface can assure highest hygienic working conditions.
