4, equipped with automatic online temperature measurement, humidity measurement device, the degree of automation is greatly improved, high uniformity of drying;

5, can automatically control the work process, automatic shutdown, simple operation, greatly reduce labor costs.

Working principle of roller scraper dryer

Drying process: Let the liquid or muddy material form a film on the surface of the drum heated by steam or other heat carriers. The drum is dried in one revolution. The product is scraped off with a scraper, and the exposed surface of the drum comes into contact with the raw material again. And form a film to dry.
The drum scraper dryer uses a certain method to spread the liquid or pasty material on the drum (hollow metal cylinder) with a 0.1-1.5mm film. The drum can be heated with steam, hot water or thermal oil. When the drum rotates once, the material can be dried and scraped off the surface of the cylinder by a special scraper. The drum scraper dryer generally rotates at a speed of 4 to 6 rpm.
The drying of the paste-like material is to adjust the thickness of the material and to compact the material layer. On the side close to the feeding device, a material compression shaft is installed to make the material evenly spread on the drum. In order to make the material easier to fall off when the scraper discharges the material, before the scraping, the cold air pipe can also be used to blow a certain amount of cold air to cool the material.
