Abstract

The invention relates to a lyophilizer, comprising a lyophilisation box with lifting board layers inside, a condensing water catcher connected with the lyophilisation box by a middle separating valve and a compressor. The lyophilizer is characterized in that air inlets of the lyophilisation box and the condensing water catcher are connected with an air supply pipe; washing openings of the lyophilisation box and the condensing water catcher are connected with a washing pipe; and discharge outlets of the lyophilisation box and the condensing water catcher are connected with a discharge pipe by discharge angle seat valves. The lyophilizer has good integrity and good lyophilisation effect and is convenient to control in the production process.

Description

technical field [0001] The invention relates to a freeze dryer, which can be applied to the fields of biological engineering, pharmaceutical industry, food industry, material science, deep processing of agricultural and sideline products and the like. Background technique [0002] The vacuum freeze-drying technology that originated in the 1920s has made great progress in the last 20 years after decades of ups and downs. In the 21st century, vacuum freeze-drying technology has become more and more popular due to its incomparable advantages over other drying methods. In addition to being widely used in the fields of medicine, biological products, food, blood products and active substances, its application scale and field Still expanding. However, most of the existing lyophilizers are bulky, complex in structure, cumbersome in operation, and poorly related to equipment. Therefore, how to solve the above problems is the research purpose of the present invention. Contents of ...
