Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as image 3 As shown, the vacuum freeze dryer shelf device of the present invention includes a shelf 1, a hydraulic column 2, a drying box 3, and the like.

[0028] Several shelves 1 are arranged equidistantly from top to bottom, and are suspended in the drying box 2, the upper and lower shelves 1 are connected by hinges 4 located at both ends of the shelves 1, and the front of the bottom shelf 1 is connected by bolts 5 is connected with drying box 3 bottoms, and every layer of shelf 1 is welded with a side plate around. The height of the welded side plates around the shelf 1 is 15mm.

[0029] During the feeding before freeze-drying and during the freeze-drying process, the entire shelf device is in a suspended state, and the shelves are horizontal, so that the thickness of the liquid freeze-dried products is placed uniformly (generally ab...

Abstract

The invention relates to a shelf device of a vacuum freeze drier. The shelf device of the vacuum freeze drier comprises shelves, a hydraulic column and a drying box. The shelves are arranged from top to bottom at equal intervals and hung inside the drying box. Every two adjacent vertical shelves are connected through hinges located at the two ends of the shelves. The front portion of the bottom-layer shelf is connected with the bottom of the drying box through bolts. A side plate is welded on the periphery of each layer shelf. According to the shelf device of the vacuum freeze drier, product trays are removed, the side plate is welded on the periphery of each layer shelf, the shelves replace the trays, and bulk pharmaceutical chemicals are directly frozen and dried on the shelves. The shelf device of the vacuum freeze drier has the advantages that contact thermal resistance does not exist between the bulk pharmaceutical chemicals and the shelves, so that the freeze-drying process is greatly accelerated, and the bulk pharmaceutical chemicals can be rapidly fed, discharged and cleaned.

Description

technical field [0001] The invention relates to a vacuum freeze dryer, in particular to a shelf device for the vacuum freeze dryer. Background technique [0002] The vacuum freeze-drying of products needs to be carried out in a certain device. This device is called a vacuum freeze dryer, or freeze dryer for short. According to the structure, the freeze dryer is composed of a drying box, a water trap, a refrigerator, a vacuum pump and valves, and an electrical control device. [0003] According to the system, the freeze dryer is composed of refrigeration system, vacuum system, control system, hydraulic system, air pressure system, heat exchange system, steam sterilization system (including in-place cleaning system). The principle of the freeze dryer is as follows: figure 1 shown. [0004] There are two types of shelves for placing products that need to be freeze-dried in the vacuum freeze dryer: [0005] First, if the half-stoppered vials are freeze-dried (water-containing...
