Conical Vacuum Dryer

Conical Vacuum Dryer

Conical vacuum dryer has a sanitary design, with a maximised heating surface, for the drying of all kinds of moist thermo-sensitive, crystalline, amorphous or paste products.
The achievable, high endvacuum ensures low drying temperatures which is a clear advantage when drying temperature-sensitive products. It also ensures good heat transfer rates and short drying times, while at the same time requiring only little energy. The short drying times and the high containment level of the fully closed system make the conical dryer the best choice in instances where environmental and/ or product requirements are strict and remarkably high.
Conical Screw Processors are used as mixers, blenders, homogenizers, reaction vessels, vacuum dryers.
Profit from all the benefits of advanced design with the Conical Screw Processor. Backed by years of experience in conical screw engineering and manufacturing

Application
 

 

Pharmaceutical, food, chemical and other industries for drying the following materials:

Applicable to slurry, paste paste, powder materials;

The heat-sensitive materials that require low-temperature drying;

Easy to oxidize, explosive, strong irritation, highly toxic materials;

Materials requiring recovery of organic solvents.

 

principle:
 

 

The heating cone is provided with a heating jacket, and the heat source is hot water, heat conducting oil or low-pressure steam, so that the inner wall of the cone is kept at a certain temperature. in operation, under the action of a vacuum pump, a certain degree of vacuum is kept in the machine, the transmission system drives the spiral belt-shaped stirring device to rotate (the spiral belt is in the form of internal heating), the material is continuously turned inside the equipment under the action of stirring, and is fully contacted with the inner wall of the cone, so that heat transfer is realized, So that the water in the material is continuously evaporated, the water vapor is led out by a vacuum pump, and the recovered liquid can be recovered by a condenser and a recovery liquid storage tank if the liquid is to be recovered. After the drying is complete, open the discharge valve of the lower part to discharge.
