Pharmaceutical drying equipment

Abstract

The invention relates to the field of universal pharmaceutical equipment, in particular to pharmaceutical drying equipment. The pharmaceutical drying equipment comprises a double-cone dryer, a hot water tank, a condenser and a vacuum pump. The hot water tank is connected with the double-cone dryer. A buffer tank is arranged between the condenser and the vacuum pump. A hot water pump is arranged at the lower end of the hot water tank. The hot water pump is connected with a hot water inlet. A vacuumizing connector is arranged at the right end of the double-cone dryer. The vacuumizing connector is connected with the condenser. The condenser is connected with the buffer tank. The buffer tank is connected with the vacuum pump. A cooling water tank is arranged at the right end of the vacuum pump. Disinfection cabinets are arranged at the two ends of the double-cone dryer. The heated surfaces of materials are replaced through the continuous rotation of a cylinder; the raw materials are heated indirectly, so that drugs are prevented from being polluted; the heat transfer efficiency is quite high, and thus more energy is saved; the vacuum effect can be well achieved through the vacuum pump, so that the drying process is highly automatic, and the pharmaceutical drying equipment is worthy of popularization.

Description

technical field [0001] The invention relates to the field of pharmaceutical general equipment, in particular to a pharmaceutical drying equipment. Background technique [0002] In the production of raw materials, most of the materials after crystallization need to be centrifuged and dried and mixed. This process is the most commonly used technical route for the production of raw materials. The solid phase substances are first separated from the suspension by filtration, and the next process will continue. It is refined in the form of vacuum or heat drying, and most of the products used in this process are double-cone rotary vacuum dryers. The reason is that it integrates mixing and vacuum drying, and can dry drugs that are prone to oxidative changes. Production reduces the chance of materials being contaminated with bacteria, and at the same time enables the solvent to move and collect independently, effectively overcoming the phenomenon of solvent loss caused by hot air dry...

[0002] In the production of raw materials, most of the materials after crystallization need to be centrifuged and dried and mixed. This process is the most commonly used technical route for the production of raw materials. The solid phase substances are first separated from the suspension by filtration, and the next process will continue. It is refined in the form of vacuum or heat drying, and most of the products used in this process are double-cone rotary vacuum dryers. The reason is that it integrates mixing and vacuum drying, and can dry drugs that are prone to oxidative changes. Production reduces the chance of materials being contaminated with bacteria, and at the same time enables the solvent to move and collect independently, effectively overcoming the phenomenon of solvent loss caused by hot air drying. The equipment is difficult to be replaced by other equipment. However, there is no good design for the double-cone rotary dryer in China at present.
