#### One, the scope of application of roller scraper dryer
Roller scraper dryer is widely used in the following fields:
- Waste salt mother liquor
- Yeast.
- Food.
- Rice paste.
- Special process food additives
- Animal and plant feed
- Milk powder to make chocolate
- Starch denaturation process
- Potato powder.
- Chemical dyes
- Pharmaceuticals.
#### Two, drum scraper dryer equipment overview
The roller scraper dryer is a continuous drying equipment with internal heating conduction, which is mainly dried by the following processes:
- The rotating drum is attached to a material film through a trough under it.
- Heat is transferred to the inner wall of the cylinder through the pipe, then conducted to the outer wall of the cylinder, and finally transferred to the material film, evaporating the wet content of the material film.
- The dried material is removed from the drum by the scraper on the surface of the drum, and falls into the spiral conveyor under the scraper, and is concentrated and packaged by the spiral conveyor.
#### Three, roller scraper dryer process characteristics
1. ** Structure and stability ** : The roller scraper dryer produced by Jiangsu Bohong Drying adopts strong structure and material, and the weight distribution is balanced.
2. ** Safety system ** : Equipped with advanced safety system to provide active protection.
3. ** Shock absorption technology ** : The use of mature shock absorption and collision avoidance technology to ensure stable and accurate operation.
4. ** Accuracy requirements ** : The accuracy of the cylinder and fuselage reaches 1/15 of the hair, ensuring the stability of operation, which is better than similar products.
#### Four, roller scraper dryer equipment advantages
1. ** High drying rate ** : Due to the thin film and the same direction of heat and mass transfer, the surface of the film can reach the vaporization strength of 70-160 kg H2O/(m²·h), which is more than 50% higher than that of ordinary scraper dryer.
2. ** Operation flexibility ** : The equipment can adjust multiple drying factors, such as feed concentration, coating concentration, coating film thickness, heating medium temperature, roller rotation speed, etc., do not interfere with each other, adapt to a variety of materials and different production requirements.
3. ** High thermal efficiency ** : thermal efficiency of more than 90%, belongs to the domestic leading level.
4. ** Short drying time ** : The drying cycle of the material is generally 10-300 seconds, suitable for heat-sensitive materials. It can be operated under vacuum conditions to further reduce the drying temperature.
