The equipment can filter, clean and dry to replace the vacuum filter, pressure filter, double conical dryers, drying oven and so on. The filtration, cleaning, drying and solid unloading can all be finished with one machine.

The dryer can realize fully-closed continuous operation in whole process. What’ more it can be used for the production of sterile required products or poisonous products, as a result of which it’s widely used in pharmaceutical, chemical, pesticide, food industry.

Functions
The equipment can make the filter cake and output finished products from the side outlet with residue less than 8mm. The product from the equipment can be directly wrapped. The whole process can be divided into three stages:

  • Filtration: separate the filter cake and mother liquor. The thickness of filter cake can be up to 500mm.
  • Cleaning: purify the filter cake. Move the residue of mother liquor first and carry out pre-dehydrating. Then mix the filter cake and washing buffer to suspend the material so that the filter cake can be fully cleaned.
  • Drying: filter cake is dried. While the filter cake is mixed by the mixer, the sidewall, the bottom of filter plate and the baffles will heat the filter cake to evaporate the water quickly. Meanwhile, the equipment will remove the air in the tank to promote the evaporation speed and pump hot nitrogen to move the steam.
