Double cone rotary vacuum dryer

Double cone rotary vacuum dryer

The Double cone rotary vacuum dryer is suitable for the concentration, mixing, drying of powder, granular and fiber in the chemical,
pharmaceutical, food and other industries, and materials that require low temperature drying (such as biochemical products, etc.). It is
more suitable for drying of easily oxidized, volatile, heat-sensitive, strongly irritating, toxic materials and materials that are not
allowed to destroy crystals.

Introduction of Double cone rotary vacuum dryer

SZG series double cone vacuum dryer is a new generation of drying device developed by our factory in combination with the technology of similar domestic products. The double cone vacuum adopts two elastic connection methods of belt and chain, so the equipment runs smoothly. The specially designed process fully reflects the good concentricity of the two shafts. The heat medium and vacuum system adopt reliable mechanical seals or American technology rotary joints. On this basis, we developed SZG-A, which can not only stepless speed regulation, but also constant temperature control.
As a professional drying equipment manufacturer, our products are available from high-temperature heat transfer oil as the heat medium, medium-temperature steam and low-temperature hot water. When drying viscous materials, our factory will specially design a “copy board” mechanism or set up balls in the tank for you.
Working principle of Double cone rotary vacuum dryer

◎The heat energy (such as hot water, low pressure steam or heat transfer oil) is passed into the closed interlayer, and the heat is
transferred to the dried material through the inner shell.
◎Under the power drive, the tank body rotates slowly, and the materials in the tank are continuously mixed, so as to achieve the purpose of
intensified drying.
◎The material is in a vacuum state, and the vapor pressure drops so that the water (solvent) on the surface of the material reaches a
saturated state and evaporates, and it is discharged and recovered by the vacuum pump in time. The water (solvent) inside the material
continuously penetrates, evaporates, and discharges to the surface. The three processes are continuously carried out, and the material
achieves the purpose of drying in a short time.

FEATURES of Double cone rotary vacuum dryer

◎The boiling point of raw material will be decreased under the vacuum condition and make theevaporator increases the pushing force of heat
transfer.
◎The heat source can be low pressure steam or waste heat;
◎The loss of the heat during the evaporation is only a little.
◎The disinfection treatment can be carried out before drying and there is no impurity material mixing during drying process. It is in
conformity with the requirement of GMP;
◎Static vacuum dryer will not damage the shape of raw materials.
