3. The evaporated solvent in the material is recovered through a condenser. Honey vacuum freeze dryer double cone rotary vacuum dryer, due to the relationship between the loading capacity of the equipment and the bulk density of the material (referring to the mass of the material per unit volume), is generally designed with a material specific gravity of 0.6 μ m/cm3. If the specific gravity is exceeded and the material is still loaded according to the original theoretical amount in the production of the flash evaporation dryer, it will affect the drying efficiency of the material; Long term operation can lead to a decrease in the lifespan of motors, reducers, sprockets, and chains, until they become unusable. In addition, some manufacturers pursue output and workers blindly operate without considering the filling rate (the ratio of the actual loading volume to the drying cylinder volume of the freeze dryer), which leads to continuous equipment operation and product quality problems of the double cone rotary vacuum dryer. And the filling rate of the double cone rotary vacuum dryer is usually between 30% and 50%. The honey vacuum freeze dryer double cone rotary vacuum dryer is a widely used equipment in the production of raw materials. This is because during the vacuum drying process, the pressure inside the cylinder is always lower than atmospheric pressure, resulting in fewer gas molecules, lower density, and lower oxygen content. Therefore, it can dry drugs that are prone to oxidative changes and reduce the chance of material contamination. Due to the fact that the temperature of water during vaporization is directly proportional to the vapor pressure, the moisture in the material can vaporize at low temperatures during vacuum drying, achieving low-temperature drying. This is particularly suitable for the production of heat sensitive materials in pharmaceuticals. At the same time, vacuum drying can eliminate the surface hardening phenomenon that is prone to occur during atmospheric hot air drying. This is due to the large pressure difference between the inside and surface of the vacuum dried material. Under the pressure gradient, moisture quickly moves towards the surface, and surface hardening does not occur. In addition, during vacuum drying, the temperature gradient between the inside and outside of the material is small, and the reverse osmosis effect allows the solvent to move and collect independently, effectively overcoming the solvent separation phenomenon caused by hot air drying. After modifying the honey vacuum freeze dryer 2, press the SET button again, and the PV screen will display the ST character to set the timer time. If the timing function is not used, still let ST=0

4. The equipment has a compact structure, occupies a small area, is easy to operate, reduces labor intensity, and saves labor. The chain drive of the double cone rotary vacuum dryer should be oiled at least once a month. The vacuum tube of the double cone rotary vacuum dryer is sealed with a rotating bearing (made of fluororubber) between the main engine and the vacuum tube. When air leakage is found, it should be replaced immediately. MOS2 composite calcium based grease (2FG-1E) is selected for the rolling bearings, with a maximum operating temperature of 150 ℃. It should be checked at least once a month. If the grease becomes dry, it should be cleaned immediately and replaced with new grease. The cylindrical turbine worm gearbox (or continuously variable transmission) should be maintained according to its instructions. After the filter inside the tank is dried once, the surrounding powder is removed to keep the filter unobstructed. Honey vacuum freeze dryer 3. Materials that require solvent recovery (properties: transparent, colorless liquid) and toxic gases; Honey vacuum freeze dryer 4. Extreme vacuum and evacuation speed. The sealing degree of extreme vacuum performance equipment and the pumping effect of vacuum pump system. The higher the vacuum degree, the better, but it should be within the most suitable range. However, the maximum vacuum of the equipment should be at least 15Pa, and the evacuation time should not exceed half an hour. If the honey vacuum freeze dryer double cone rotary vacuum dryer can be effectively applied in production, it must be a systematic concept, in which the organic solvent recovery system is a key process. When manufacturers supply double cone rotary vacuum drying equipment, they should not only provide single machines, but also provide systems, and consider the recovery of organic solvents. Due to the low boiling point of solvents, frozen water is used for condensation cooling to ensure that the solvents can be recycled and avoid polluting the atmosphere after being pumped out by vacuum pumps.

(2) In the process of filtration and washing, multifunctional drying equipment can overcome the disadvantages of low efficiency, excessive "gross points", high operating intensity, resource waste, difficult cleaning and disinfection (sterilization), and large footprint caused by the original process configuration of equipment such as filters, centrifuges, and pressure filters. From the above, it can be seen that the angle of the cone of the double cone rotary vacuum dryer can affect the stirring and mixing effect, and the material drying surface formed by it ultimately affects the drying speed. Similarly, an excessively high filling rate of the actual loading volume can also affect the flipping mixing effect and the drying speed. Before using the honey vacuum freeze dryer, precautions should be taken. The moisture in the wet material in the vacuum dryer will evaporate after absorbing heat, and a certain amount of air will be pumped out through the exhaust pipe. Then, the interior of the vacuum dryer will be in a special state, which can make the raw material constantly flip up and down, inside and outside, accelerating the drying speed and improving the drying efficiency. Of course, if some preparations are not made before operation, it will affect the working efficiency of the vacuum dryer. (2) The normal situation of leakage at the inlet and outlet is due to damaged sealing strips, which only need to be replaced. Although the double cone rotary vacuum dryer still has some problems in the production process, it has great advantages compared to general vacuum dryers As long as our workers strengthen their understanding of the machine and use it in a standardized manner during production operations, its value is very high
