The static vacuum dryer adopts a two-stage elastic connection mode of belt/chain, so the equipment runs smoothly. The specially designed process fully reflects the good concentricity of the two shafts. Both the heat medium and the vacuum system use reliable mechanical seals or American technology rotary joints. The machine can not only stepless speed regulation, but also constant temperature control.
The material of the static vacuum dryer is always at a low temperature (frozen state) before drying, and the ice crystals are evenly distributed in the material. The sublimation process will not cause condensation 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 soluble in water and returns to its original state. Physicochemical and biological denaturation of dry substances is prevented to the greatest extent possible.
The vacuum dryer rotates at a low speed with the tank body, and the material moves up and down in the tank continuously, and moves in a "diamond-shaped trajectory" inside and outside the tank, absorbs and evaporates, and the water vapor is continuously discharged through the vacuum pipeline to achieve the purpose of drying the material. While drying the mixture, the built-in spraying, filtering, pulverizing and other devices can realize its multi-functional operation according to customer requirements. It is suitable for drying of easily oxidized, volatile, strongly heat-sensitive, toxic materials and materials that are not allowed to destroy crystals.
