Abstract

The invention provides a vacuum spray-freezing granulation device and a method thereof. The device of the invention is characterized in that the device comprises a container; multiple atomizing nozzles used for atomizing and dispersing a liquid to be freeze-dried into liquid drops are arranged inside the container; and the container is connected to a vacuum system used for forming a vacuum environment in the container to make part components in the liquid drops to be vaporized and absorb heat in the vacuum environment so as to further cool and freeze the liquid drops to form granules. The method of the invention is completely different from a traditional freeze-drying granulation technology. By vacuum-pumping to freeze atomized liquid drops into granules, freezing rate of the liquid to be freeze-dried is greatly raised. According to the vacuum spray-freezing granulation device, a refrigerant nozzle is not arranged therein, a liquid nitrogen low-temperature zone is not arranged in the device, and a refrigerant is completely not used to contact with a material during the quick-freezing process so as to completely eradicate the risk that the material is polluted. Therefore, sterility of the freeze-drying process is raised, production energy consumption is reduced, and the environment will not be polluted.

Description

technical field [0001] The invention relates to a vacuum spray freezing granulation device and method. Background technique [0002] In the freeze-drying process, the liquid to be freeze-dried needs to be frozen into ice, and then dried at a low temperature under vacuum to sublimate the ice and leave dry matter. Conventional freeze-drying technology freezes the liquid to be freeze-dried into ice cubes under normal pressure. It is a slow freezing technology. The liquid drops from room temperature (25°C) to -40°C for more than 30 minutes. (such as suspensions, emulsions), material sedimentation and liquid stratification are prone to occur; and slow freezing is prone to ice crystal growth, which is not conducive to freeze-drying. [0003] The U.S. Patent Publication No. US20130118026A1 discloses a spray quick-freezing technology, which sprays the liquid to be freeze-dried from the top of the container with a nozzle, and sprays a refrigerant (such as liquid nitrogen, boiling po...
