Vacuum freeze drying device

Abstract

The invention relates to a vacuum freeze-drying device. The vacuum freeze-drying device comprises a drying box with a placing opening, a rotating frame with a hollow structure and a medicine storage barrel are arranged inside the drying box, the rotating frame is rotationally connected to the rear wall of the interior of the drying box through a rotating shaft, the interior of the rotating frame is hollow, a mounting opening is arranged in one side, facing the placing opening, of the rotating frame, and the medicine storage barrel is inserted into the rotating frame through the mounting opening of the rotating frame and is fixedly connected with the rotating frame; the medicine storage barrel rotates synchronously when the rotating frame rotates, a plurality of air holes are arranged in the surface of the medicine storing barrel, and a driving device used for driving the rotating frame to rotate is arranged on the drying box. According to the vacuum freeze-drying device, and the effectof uniform drying effect of medicinal materials in the freeze-drying process can be achieved.

Description

technical field [0001] The invention relates to medicinal material production and processing equipment, in particular to a vacuum freeze-drying device. Background technique [0002] After the medicinal materials are softened and cut, the water content in the medicinal materials is extremely high. In order to prevent the medicinal materials from deteriorating, it is necessary to dry the medicinal materials in time. In the prior art, the drying of medicinal materials is generally carried out by drying to remove the moisture in the medicinal materials. Although the method of drying can basically reduce the deterioration of the medicinal effect cost in the medicinal materials, the efficiency of drying is very low and is greatly restricted by the weather. There is also a way to use a dryer to dry the medicinal materials. When the medicinal materials are dried, a freeze dryer is used for freeze-drying. A method of preserving a substance by removing water. [0003] Freeze vacuum ...

AI Technical Summary

Problems solved by technology

Because the material in the material tray has a certain thickness, there is a certain degree of covering between the material and the adjacent material, so the heating of the covered material is not uniform, and the material on the surface is always dried first, and then the inner layer or bottom layer The material is dry, so the drying cycle of the static material is generally more than 12 hours, which leads to low drying efficiency of the material
