Product Description

220v/380v Potato Powder Drum Chemical Dye Rotary Dryer Liquid

Drum Scraper Dryer Equipment  

HG Series Compact Structure Rotary Drum Scraper Dryer is a kind of rotating continuous drying equipment with internal heating conducting function. The material film will stick to the bottom of the rotating cylinder. The heat is transferred to the internal wall of the cylinder through piping system and it will be conducted to the external wall and material film. The moisture of the wet material film will be easily evaporated and the dried material will be scraped from the cylinder surface and transfer to the packing area by the screw conveyor.

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.

Technical parameters

Applications

It can quickly dehydrate and dry materials with high humidity to achieve the effect of turning waste into treasures. It is one of the most important dehydration and drying equipment in the drying industry. It is suitable for drying liquid and viscous materials in chemical, dye, pharmaceutical, food, metallurgy, yeast and other industries.

Features of drum scraper dryer

Taking the steam or oil as the heat source. The heated area is big. The heat efficiency is high. Heating is uniform.
The drying speed rate is big. The heat transmission for the wet materials on the cylinder wall is from the inside to the outside and uniform. The temperature gradient is big so as to make that the film surface keeps the stronger evaporation strength
The drying time is short, some 10 - 15s. The machine is suitable for the heat sensitive materials.
The operation is simple. And the maintenance is easy.
