SZG double cone rotary vacuum dryer

Product overview
　　 SZG 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 belt-chain two elastic connections, so the equipment runs smoothly. The specially designed process fully reflects the good concentricity of the two shafts. The heat medium and vacuum systems use reliable mechanical seals or American technology rotary joints. On this basis, we developed SZG-A, which can not only adjust the speed steplessly, but also perform constant temperature control.
　　 As a professional drying equipment manufacturer, our products range from high-temperature heat transfer oil as heat medium, medium-temperature steam and low-temperature hot water. When drying viscous materials, our factory will specially design a "scraping board" mechanism or set balls in the tank for you.
Working principle
◎Heat energy (such as hot water, low-pressure steam or heat transfer oil) is introduced into the airtight interlayer, and the heat is transferred to the material to be dried through the inner shell.
◎Driven by power, 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 is discharged and recovered by the vacuum pump in time. The water (solvent) inside the material continuously penetrates to the surface, evaporates, and discharges three processes continuously, and the material achieves the purpose of drying in a short time.
Performance characteristics
◎When the oil is heated. Using automatic constant temperature control. It can dry biochemical products
◎ and mineral raw materials, the temperature can be between 20 ~ 160 o C.
◎The thermal efficiency is high, which is more than 2 times higher than that of ordinary ovens.
◎Indirect heating. The material will not be polluted and meets the requirements of "GMP". Equipment maintenance is simple and easy to clean.
◎Recommended Process Placement Demonstration Process Placement for Solvent Recovery.
Adapt to material
　 　It is suitable for concentration, mixing and drying of powder, granular and fiber in chemical, pharmaceutical, food and other industries, as well as materials that need low-temperature drying (such as biochemical products, etc.). It is more suitable for the drying of easily oxidized, volatile, heat-sensitive, strongly irritating, toxic materials and materials that are not allowed to destroy crystals.

FZG/YZG Square, Round Static Vacuum Dryer

Working principle
The so-called vacuum drying is to heat and dry the dry material under vacuum conditions. If the vacuum pump is used for dehumidification, the drying speed will be accelerated.
Note: If a condenser is used. The solvent in the material can be recovered through the condenser. If the solvent is water, the condenser is not needed, saving energy investment.
Performance characteristics
◎The boiling point of the material solution is lowered under vacuum. The heat transfer driving force of the evaporator is increased, so the heat transfer area of ​​the evaporator can be saved for a certain amount of heat transfer.
◎The heat source of evaporation operation can be low-pressure steam or waste heat steam.
◎The evaporator has less heat loss.
◎Sterilization treatment can be carried out before drying, and no impurity is polluted during the drying process, which meets the requirements of GMP.
◎It is a static vacuum dryer, so the shape of the dried material will not be damaged.
Suitable for materials
It is suitable for low temperature drying of heat-sensitive materials that are easy to decompose, polymerize and deteriorate at high temperatures; it is widely used in pharmaceutical, chemical, food, electronics and other industries.

Vacuum rake dryer

The interlayer and mixing shaft of the machine are heated at the same time, with large heat transfer surface and high thermal efficiency.
The mixing shaft of the machine can rotate in a positive and reverse direction, so that the material can form a continuous circulation state in the cylinder, further improving the uniformity of material heating.
The mixing shaft of the machine adopts spiral distribution, so that the slurry, paste and paste materials can be dried smoothly.

Vacuum rake dryer This machine is applied to:
The following materials are dried in pharmaceutical, food, chemical and other industries
Applicable to paste, paste and powder materials
Heat sensitive materials requiring low temperature drying
Easily oxidized, explosive, highly irritating and highly toxic materials
Materials requiring recovery of organic solvents

Square vacuum dryer

Double cone rotary vacuum dryer

The main machine of the double cone rotary vacuum dryer is a double cone tank. In the vacuum state of the tank, steam or hot water can be passed into the jacket to heat the inner bladder. Heat is transferred to the wet material through the inner bladder to make the moisture in the wet material gasification. Equipment compact structure, small footprint, easy to operate, reduce labor intensity, labor saving.
The double cone rotary vacuum dryer has advanced design, simple internal structure, easy cleaning, all the materials can be discharged, simple operation.
It is suitable for concentration, mixing and drying of powder, granular and fibrous materials in chemical, pharmaceutical, food and other industries, as well as materials requiring low temperature drying (such as biochemical products, etc.). It is also suitable for drying materials with easy oxidation, volatile, heat sensitivity, strong stimulation, toxicity and materials that are not allowed to destroy crystals.
