Model Is SWGF1850A Name Is Rendering Disc Dryer Disc Dryer

1,With the saturated steam, hot water or heat conducting oil as heating medium, the vacuum rake dryer is an energy-saving and indirectheating drying equipment, which can be intermittently operated to dry the materials in vacuum condition.

2,It can be mainly used for thedrying of slurry, paste, granular, powder, fiber, easily oxidized, heat sensitive materials.

Continuous vacuum

Freeze drying is a technology that uses the principle of sublimation to dry. It is a process in which the dried material is frozen quickly at a low temperature, and then in a suitable vacuum environment, the frozen water molecules are directly sublimated into water vapor to escape. Freezing The product obtained by drying is called a lyophilizer, and the process is called lyophilization.

The substance is always at a low temperature (frozen state) before drying, and the ice crystals are evenly distributed in the substance. The sublimation process will not be concentrated due to dehydration, and avoid side effects such as foaming and oxidation caused by water vapor. The dry substance is porous in the form of a dry sponge, the volume is basically unchanged, and it is easily dissolved in water to restore its original shape. To the greatest extent, prevent the physical, chemical and biological denaturation of dry substances.

Each layer of heating plate has heat carrier inlet and outlet pipes. Generally, the upper layers use low-pressure saturated steam or hot water, hot oil in series, parallel or series-parallel input heating to control the temperature of each layer; while the bottom two layers are supplied with cooling water, To reduce product temperature, recover heat, and ensure quality. The heating plate is fixed on the cylinder frame at a certain interval and placed horizontally.

Each layer is equipped with a cross arm frame, and the upper and lower layers are staggered and fixed on the central main shaft by a worm gear reducer and a continuously variable transmission. Driven by motor and motor, rotate slowly at 0.6~3.7(r/min). Each arm frame is equipped with multiple detachable plow-shaped rake blades or flat scrapers, which are arranged at equal intervals. The harrow blade adopts a hinged and reed swing structure to make the bottom edge float on the disc surface. The angle of the harrow blade can be adjusted arbitrarily according to the material properties to ensure the continuous advancement of the material on the disc surface.
