Problems solved by technology
[0003] Because the existing crystallization equipment is working, because it is difficult to quickly collect the crystallization, because the crystallization inside the shell is not disposed of in time after a long period of cooling, and at the same time, excessive crystallization may affect the subsequent process, which may easily lead to cooling effects. After a long time of use, it may cause a large amount of crystals in the shell to be difficult to collect in time. At the same time, because it is not easy to clean, it is not conducive to the long-term use of the crystallization equipment.

The invention discloses desublimation crystallization equipment. The equipment structurally comprises a hot air port, a crystallization mechanism and a shell, the crystallization mechanism is arrangedin the shell, a distillation crystallization device and an auxiliary crystallization device are arranged in the shell, the distillation crystallization device is respectively matched with a raw material port and a distillation port, and the auxiliary crystallization device is arranged between the two ports. The auxiliary crystallization device is arranged in the shell, crystallization is accelerated by utilizing an air blowing mechanism to produce air flow, and raw material water vapor and distillation cold air are adsorbed to a crystallization rod, so that the overall temperature in the shell is reduced in time, desublimation crystallization is carried out, crystallization equipment can be cooled more quickly and efficiently, and the efficiency of the crystallization equipment is effectively improved; and airflow brought by an air blower is used for accelerating cooling, and the overall desublimation and crystallization speed is increased.
Description
technical field [0001] The invention is a sublimation crystallization equipment, which belongs to the field of chemical equipment. Background technique [0002] Sublimation crystallization equipment Evaporation crystallization process is a commonly used operating unit in pharmaceutical and chemical processes, and is widely used in the production process of almost all crystalline drugs. At present, the evaporative crystallization commonly used by enterprises mainly includes heat convection type and forced circulation type. The above two types of evaporative crystallizers are mostly forced external circulation evaporative crystallizers. The principle of this evaporator is to heat the material solution in the external heater under the action of the pump, and evaporate it in the evaporator. After so many cycles, when the solution concentration exceeds the solubility at this temperature, the solute precipitates and crystallizes. In this state The solution in which crystals have...
