Cold air system applied to raw material medicine production plant

Abstract

The invention relates to the technical field of medicine processing equipment, in particular to a cold air system applied to a raw material medicine production workshop, which comprises a constant temperature and humidity chamber, a filter, a centrifugal fan, a plate heat exchanger, a low temperature dehumidifier, a rolling boiling bed, a cyclone dust collector and a wet dust collector, the filter is provided with a fresh air port, one end of the filter is connected with the centrifugal fan, the centrifugal fan is respectively connected with the plate heat exchanger and the low-temperature dehumidifier, the rolling fluidized bed is respectively connected with the low-temperature dehumidifier and the plate heat exchanger, the rolling fluidized bed is connected with the cyclone dust collector, the cyclone dust collector is connected with the wet dust collector, and the wet dust collector is provided with an exhaust port. In practical application, effective control over the temperature and humidity of cold air of the rolling fluidized bed is achieved by applying the system, moisture regain and caking in the production and storage process of the raw material sodium chloride are prevented from the source, the quality of the raw material sodium chloride product is improved, and good economic benefits are achieved.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical processing equipment, in particular to a cold air system applied to raw material medicine production workshops. Background technique [0002] The raw material sodium chloride is an electrolyte replenishing drug, which is mainly used in the preparation of sodium chloride injection, compound sodium chloride injection, dialysis powder, dialysis solution and sodium-containing raw material salt, etc. However, during the production and storage of sodium chloride, there are caking and deliquescence, which seriously affect product quality. [0003] At present, there are two common methods to prevent sodium chloride agglomeration: one is to add anti-caking agent to inhibit the growth of sodium chloride crystals and avoid salt crystal agglomeration, but it cannot prevent sodium chloride crystals from absorbing moisture and becoming damp; It is because an appropriate amount of loosening agent is adde...
