The working principle of the beer yeast dryer is mainly based on the internal heating conduction type rotary continuous drying technology.
When the beer yeast dryer (such as the HG series drum scraper dryer) is working, the beer yeast stock solution or muddy material is evenly applied to the outer surface of the drum (drum) through a specific spreading method. As the drum rotates, these materials form a thin film on the outer surface of the drum. The heat is transported to the inner wall of the drum through the pipeline, then transferred to the outer wall of the drum, and further transferred to the material film attached to the outer surface of the drum. The moisture in the material film evaporates rapidly after being heated, thereby achieving dehumidification and drying. When the dried material film reaches the scraper part, it is peeled off from the drum surface by the scraper and falls into the screw conveyor below. The screw conveyor then collects the dried material and transports it to the subsequent process or packaging equipment.
Technical features of yeast dryer
1. High thermal efficiency: Since the heat transfer mechanism belongs to heat conduction and the heat transfer direction remains consistent throughout the entire operation cycle, the thermal efficiency is high, usually up to 70%-80%.
2. High operational flexibility: The equipment can adjust multiple drying factors, such as feed concentration, film thickness, heating medium temperature, drum speed, etc., to meet the drying needs of different materials and different production requirements.
3. Short drying time: The drying cycle of the material is generally only 10-300 seconds, which is particularly suitable for the drying of heat-sensitive materials.
4. High drying rate: Since the film is very thin (generally 0.3-1.5mm), and the heat and mass transfer directions are consistent, the film surface can maintain a high evaporation intensity, generally up to 20-70kg.H2O/m2.h.
Yeast drum dryer equipment is not only suitable for the drying of beer yeast, but also for the drying of other similar materials, such as sweet potato powder, pumpkin powd
