Double cone rotary vacuum dryer is a dryer set mixing, drying in one. The condenser, vacuum pump and drying system, vacuum drying device (if not need solvent recovery, the condenser can not). This machine has advanced design, simple structure, easy cleaning, materials can be completely discharged, simple operation. Can reduce the labor intensity and improve the working environment. At the same time because the container itself rotates material also rotates but the wall of the material is not deposited, so the heat transfer coefficient is high, the drying rate, not only to save energy, and even drying of the material fully, good quality.
Double cone rotary vacuum dryer vacuum drying, double cone rotary vacuum dryer cylinder pressure is always lower than the atmospheric pressure, molecule number is less, low density, low oxygen, so it can dry easily oxidized drugs, less material contamination opportunity. The working principle of double cone rotary vacuum dryer is a container holding Walter heat medium, the heat from the cylinder wall to dry materials, motor rotating the barrel, barrel material continuously contacting the cylinder wall, mixed, so as to enhance heat transfer. Dry materials in the air condition, the rapid evaporation of water or solvent, and the vacuum pump and recycling, thus to vacuum low temperature drying purposes. Because the water in the vaporization process temperature and steam pressure is proportional to, so the vacuum dry, the water in the material can reach at low temperature gasification, low temperature drying, double cone rotary vacuum drying machine especially for heat sensitive materials production. Because the water in the vaporization process temperature and steam pressure is proportional to, so the vacuum dry, the water in the material can reach at low temperature gasification, low temperature drying, double cone rotary vacuum drying machine especially for heat sensitive materials production. Double cone rotary vacuum dryer installation should pay attention to the foot loose, worm gear reducer, bearing damage, damage to the application of AC bad chain too loose or too tight caused by excessive noise.
Double cone rotary vacuum dryer in the use process first note quantity of material delivery, because the bulk density, loading and material double cone rotary vacuum dryer (of a unit volume of material quality), under normal circumstances, design the proportion of materials by 0.6 Bei /cm3 to calculate. Double cone rotary vacuum dryer in the use process first note quantity of material delivery, because the bulk density, loading and material double cone rotary vacuum dryer (of a unit volume of material quality), under normal circumstances, design the proportion of materials by 0.6 Bei /cm3 to calculate. If you exceed this proportion, one will affect the efficiency of drying materials; two is the long time operation leads to the decrease of motor, reducer and sprocket chain, life, until can't use. In addition, some manufacturers in pursuit of production and workers operate blindly, regardless of its filling rate (frozen actual loading volume and dry drier than simplified volume), leading to quality problems of equipment operation and product double cone rotary vacuum dryer continuously. And double cone rotary vacuum dryer filling rate is usually between 30%~50%.
Double cone rotary vacuum dryer will often appear vacuum is not enough or too high in the drying process, which is usually 3 reasons: (1) the vacuum end mechanical seal leakage; (2) the vacuum pipeline leakage or blockage; (3) the filter blocked plastic dryer plug. This needs to be examined in the use process, at the same time to maintenance, cleaning etc..以上結果由提供 |
