Thermal-uniformity tray for freeze dryer

Abstract

The invention discloses a thermal-uniformity tray for a freeze dryer. The thermal-uniformity tray for the freeze dryer comprises a tray main body, wherein the tray main body is of a solid rectangularstructure, the bottom surface contacting with the partition of the freeze dryer, of the tray main body, is a plane, and the top surface of the tray main body is a concave surface; a plurality of uniformly-distributed groove holes are chiseled in the tray main body, the bottom end of each groove hole is a blind hole, the top end of the groove hole is of an open structure, and the vertical distancebetween the blind hole end of each groove hole and the bottom surface of the tray main body is gradually increased from the middle part of the tray main body to the four sides of the tray main body; and the height of each groove hole is the same. The thermal-uniformity tray for the freeze dryer is simple in structure, and reasonable and novel in design; the heat transfer speed at any position on the whole tray main body is the same through the own structure of the tray main body and the design that the groove holes for holding penicillin bottles are formed at positions on the tray main body, so that the same freeze drying speed for a sample to be subjected to freeze drying, at any position on the whole tray main body, is ensured, and the freeze drying effect is improved.

Description

technical field [0001] The invention relates to the field of freeze-drying technical equipment, in particular to a thermal uniformity freeze-drying machine tray. Background technique [0002] Freeze dryer is the equipment for freeze-drying medicine and food in the pharmaceutical industry and food industry. It first freezes the items (products) to be freeze-dried at low temperature, and then under vacuum conditions, through vacuum sublimation and analytical adsorption. The moisture content of the product is reduced to a level where the biological and chemical reactions cannot be maintained for a prolonged period of time. The tray is an essential tool for transshipment and holding the items to be freeze-dried, and putting the items to be freeze-dried on the shelf of the freeze dryer through the tray for freezing. Therefore, the heat transfer effect of the tray is also one of the main factors affecting the freeze-drying effect and freeze-drying efficiency of the items to be fr...
