Shelf structure for vacuum freeze drying equipment

Abstract

The invention relates to the technical field of biological medicine manufacturing, and discloses a shelf structure for vacuum freeze drying equipment. The shelf structure comprises a shelf seat; the upper end of the shelf seat is rotatably connected with a rotary shelf; a sealing lantern ring is arranged between the shelf seat and the rotary shelf; and the front end and the rear end of the shelf seat are respectively provided with a liquid inlet and a liquid outlet. A combined structure of the shelf seat and the rotary shelf is used for replacing a traditional shelf, so that the rotary shelf can rotate on the shelf seat, materials located on the rotary shelf can be evenly heated, the temperature difference between the materials on the rotary shelf is reduced, the consistency of the quality of the materials is improved, in addition, the temperatures of the front end and the rear end of the rotary shelf are measured through a front-end temperature sensing bulb and a rear-end temperature sensing bulb, the effect of automatically adjusting the rotating speed of the rotary shelf according to a temperature difference value is achieved through the combined action of a water quantity control mechanism and the area change of arc-shaped wheel blades, and the automation of temperature adjustment is improved.

Description

technical field [0001] The invention relates to the technical field of biopharmaceutical manufacturing, in particular to a shelf structure for vacuum freeze-drying equipment. Background technique [0002] At present, with the continuous development of freeze-drying technology and freeze-drying machine technology, freeze-drying is more and more widely used in the development of sterile preparations, especially in the production and manufacture of pharmaceuticals, playing an irreplaceable role. The main purpose of drug freeze-drying is to maintain its activity, and freeze-drying can keep the drug from deteriorating, which is suitable for long-term storage and has good rehydration, especially for injections. The medical staff and patients no longer need to shake and melt the freeze-dried injections. It is water-soluble. [0003] The shelf is used to place the material that needs to be freeze-dried, and the material is refrigerated or heated through the shelf, so that the mater...
