Professional Industrial Scraper Double Drum Dryer For Active Dry Yeast
The same set of deceleration transmission device meshes with a pair of gears with the same modulus and number of teeth to make two sets of rollers with the same diameter rotate relative to each other. According to the different positions of the cloth film, it is divided into two types: the roll type and the same groove type.
Product Working Principle
The drum dryer is a continuous operation device that dries the liquid phase material or ribbon material attached to the outer wall of the cylinder by means of heat conduction through a rotating cylinder. The material liquid to be dried flows into the material receiving tank of the drum dryer from the upper tank. The drying drum is driven by the transmission device, and the material is formed by the filming device to form a material film on the wall of the drum. The cylinder is heated continuously, and the moisture of the material film is vaporized by the heat transfer from the cylinder wall, and the material is scraped off by a scraper, and then conveyed to the storage tank through a screw for packaging. It has high thermal efficiency and can be operated continuously, so it is widely used in the drying of liquid materials or strip-shaped materials, and is more suitable for paste-like and viscous materials.
Product Features
1) High thermal efficiency: Most of the heat supplied in the cylinder is used for moisture vaporization, and the thermal efficiency can be as high as 70~80%.
2) Large drying rate: The heat and mass transfer process of the wet material film on the cylinder wall is consistent from the inside to the outside, and the temperature gradient is large, so that the surface of the material film maintains a high evaporation intensity, generally up to 30kg/㎡ h.
3) The drying quality of the product is stable: the heating method of the drum is easy to control, the temperature in the cylinder and the heat transfer rate of the partition wall can be kept relatively stable, so that the material film can be dried in a stable heat transfer state, and the quality of the product can be guaranteed.
4) Wide application range: Liquid phase materials dried by drums have fluidity, adhesion and stability to heat. The form of the material can be solution, suspension, emulsion, sol, etc.
5) The production capacity of a single machine is limited by the size of the cylinder: the drying area of a general drum dryer should not be too large. The drying area of a single cylinder seldom exceeds 12 square meters, and its processing capacity is generally 50-1000kg/h.
Product Application
This dryer is suitable for drying liquid raw material or sticky material in chemical industry, dyestuff industry, pharmaceutical industry, foodstuff industry, and metallurgy industry, and etc.
