Double cone rotary vacuum dryer with a hot water heating type double cone rotary vacuum dryer, heat conducting oil heating high temperature type double cone rotary vacuum dryer, the steam heating type double cone rotary vacuum dryer and the electrical heating high temperature double cone rotary vacuum dryer (wrapped in the tank body of the electric heating element), belongs to the dynamic vacuum drying equipment.
Double cone rotary vacuum dryer is a new type of dryer drying in one of the mixed -. The condenser, vacuum pump and drying system, vacuum drying device. (such as the solvent to be recovered, the condenser can not) this machine has advanced design, simple structure, easy cleaning, the material can be fully discharged, simple operation. Can reduce the labor intensity and improve the working environment. At the same time because the container itself rotary material material also rotates but the container does not accumulate material, the heat transfer coefficient is high, the drying rate are high, not only to save energy, and even drying of the material fully, good quality. Double cone rotary vacuum dryer body slightly as the olive shape, both ends of the cover is arranged in the middle of the two, to support the body. Double cone rotary vacuum dryer with a jacket to heating, drying device, rotary, material and wall replaced frequently contact, overcome material vacuum oven mainly depends on the heating cylinder conduction and low heat efficiency. Double cone rotary vacuum dryer in fine chemical industry, medicine and so on have been widely used in high viscosity, or during the rotation process strongly adhesive material is not applicable. Double cone rotary vacuum dryer is mainly used in pharmaceutical, chemical, food and other industries of powder, granular and fibrillar material concentration, mixing, drying and low temperature drying material (such as biochemical products), more suitable for easy oxidation, volatile, toxic materials, heat sensitive strong stimulation and does not allow the destruction of the crystal materials drying.
Double cone rotary vacuum dryer widely used in biochemistry, chemical pharmaceutical, medical and health, agricultural research, environmental protection and other research fields, for dry powder, baking and all kinds of glass containers disinfection and sterilization with. Particularly suitable for fast and efficient drying process for drying heat sensitive, easily decomposed, easily oxidized substance and complexity of the component items. Do you know how to operate? In the step of what needs attention.
1, add the workpiece to gas is pumped to workpiece material can be pumped to the composition of vacuum double cone rotary vacuum dryer vacuum drying box. If the first heating, gas heat expands. Because the vacuum box seal is very good, great pressure expansion generated gas may make the observation window glass burst. This is a potentially dangerous. According to the first vacuum and heating heating operation procedures, you can avoid the danger.
2, if the operation procedures according to the first heating and vacuum pumping, heating air vacuum pump out of the heat, will be brought to the vacuum pump up, resulting in high temperature vacuum pump, vacuum pump efficiency is likely to decline.
The 3 gas, heated by guiding the vacuum pressure gauge, will produce a temperature rise of the vacuum pressure gauge. If the temperature exceeds the vacuum pressure gauge using the specified temperature range, may make the vacuum pressure shown value error table.
Double cone rotary vacuum dryer shell shaped by stamping steel bending, welding, shell surface using electrostatic spray coating processing of high strength, the film is smooth and firm. The studio made of carbon steel plate or stainless steel plate bending and welding, between the studio and the shell is filled with insulation cotton. The studio is placed inside the sample shelf, used for placing various test items, around the outer wall of the chamber with a mica heater. The door seal with silicone rubber seal, is arranged on the box door can be observed by the mirror. Evacuation with inflatable electrothermal vacuum drying box is controlled by electromagnetic valve, the electrical box on the left or the lower box body, the front panel is arranged on the electrical box with vacuum gauge, temperature control instrumentation and control switch, electric appliance box is provided with electrical components.
Thermal energy is fed into the sealed jacket (such as hot water, low pressure, steam or thermal oil), heat the inner shell to dry materials. Under driving of power, the tank is rotated slowly, mixed material double cone rotary vacuum dryer tank constantly, so as to strengthen the purpose of drying. The material in the vacuum state, the vapor pressure drops to the material moisture (solvent) saturated and evaporation, and the vacuum pump to discharge recovery. The material internal moisture (solvent) continue to surface infiltration, evaporation, discharge, three ongoing process, material to achieve the purpose of drying in a very short period of time. |
