Continuous vacuum fluidization freeze drying device

Abstract

The invention relates to the technical field of material freeze drying devices and discloses a continuous vacuum fluidization freeze drying device. The continuous vacuum fluidization freeze drying device comprises a vacuum chamber. One end of the vacuum chamber is connected with a vacuum chamber maintenance and overhaul end cover. The upper end of the vacuum chamber communicates with a feed port mechanism. The position, close to the lower end, of the chamber wall of the vacuum chamber communicates with a discharge port mechanism. The vacuum chamber communicates with a vacuum port. Unpowered material tray conveying constant-temperature table boards are mounted in the vacuum chamber. The unpowered material tray conveying constant-temperature table boards include the multiple layers of constant-temperature table boards vertically distributed in the horizontal direction. Each layer of constant-temperature table board comprises a plurality of constant-temperature table board modules. The continuous vacuum fluidization freeze drying device can well meet the requirements for continuity, batches and accuracy of the powder drying process in the food and drug industries, especially the pharmaceutical industry, and GMP mass production of medical equipment can be achieved. Meanwhile, the problems that materials are prone to caking and the drying effect of the materials is affected are solved.

Description

technical field [0001] The invention relates to the technical field of freeze-drying devices, in particular to a continuous vacuum fluidized freeze-drying device. Background technique [0002] Vacuum drying equipment for materials such as food, pharmaceuticals, or other powders on the market. The vacuum drying equipment vacuum-dries materials in a vacuum state of negative pressure, which solves the problem of high hot air temperature, poor quality of materials after drying, and active ingredients in materials. The problem of reduction, batching is not obvious, and materials are easy to form agglomerates. Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a continuous vacuum fluidized freeze-drying device, which can well solve the problem of continuous, batch-oriented, precise drying of food and medicine, especially powder in the pharmaceutical industry The equipment can mee...
