Double cone rotary vacuum dryer uniform heating due to heating, from the inside to the outside of the materials are heated at the same time, the temperature difference between inside and outside the material is very small, not internal and external heating appears in practice heating inconsistent condition, resulting in the effect of expansion, to smash, the drying quality is greatly improved. Double cone rotary vacuum dryer with significant economic benefits. From the characteristics of above introduction, energy consumption, improve product quality, safety, health and sustainable development of vacuum drier equipment investment interest etc. aspects of it can be seen that the economic benefit and social benefit significantly.
Double cone rotary vacuum dryer, vacuum environment greatly reduces the need to dispel the boiling point of liquid, so the vacuum drying can be easily applied to the heat sensitive material, workpiece into to gas is pumped to workpiece material can be pumped to a vacuum double cone rotary 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 heating again sequential operation of heating, can prevent this danger. If the sequence of operations 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. Gas heated is guided by 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 gauge has shown value error.
Standard double cone rotary vacuum dryer for material requirements:
Direct contact with a, and the material equipment and parts surface to smooth the state, to achieve easy disinfection, cleaning. And the material close contact parts are must be non-toxic, corrosion resistance, not with the drug reactions and no drug adsorption capacity, should be equipped with a material document for proof. Stainless steel plate shall be in accordance with the "hot rolled stainless steel sheets and plates" that the requirements of the national standard.
Lubrication is not B, transmission parts of the phenomenon of oil leakage. Living machine transmission parts and the outer surface of the pot with a stainless steel plate, coated smooth without bump defects. Double cone rotary vacuum dryer is sensitive, reliable operating system; transmission system without jamming phenomenon and abnormal sound, steady slew tank. Running noise less than 85 decibels. |
