Full-automatic ethanol addition system for blood product production

Abstract

The invention relates to a full-automatic ethanol addition system for blood product production. The full-automatic ethanol addition system comprises an ethanol storage system, an ethanol distribution system and a storage tank, wherein the ethanol storage system comprises a storage tank ethanol addition system for controlling the storage amount of ethanol in the storage tank and a storage tank breathing system for achieving pressure balance in the storage tank; the ethanol distribution system comprises an ethanol circulation system for controlling the temperature and the pressure of ethanol and multiple ethanol addition systems for adding ethanol to use points according to the addition requirements. The full-automatic ethanol addition system is reasonable in structure, and simple and convenient to use, the problems of large workload, complicated operation and multiple uncontrollable factors in the addition process in an existing artificial ethanol addition method are solved, and the labor intensity and the workload of a worker are greatly reduced. The ethanol continuously circulates in the ethanol storage system and the ethanol distribution system, uniform quality characteristics of the ethanol in the whole system are achieved, and the temperature and the addition speed of the ethanol added to the reaction system meet the process requirements.

Description

technical field [0001] The invention relates to an ethanol addition system, in particular to a fully automatic and high-precision ethanol addition system used in the production of blood products. Background technique [0002] At present, the low-temperature ethanol method is mainly used for protein separation in blood products. The principle is to add ethanol to the protein solution to reduce the activity of water molecules, reduce the dielectric constant of the solution, and repel water molecules from around the protein molecules, so that the protein molecules Agglomeration occurs through the interaction of polar groups and under the action of van der Waals force. The ethanol concentration and solution temperature in this method are extremely important factors in the protein separation reaction. [0003] The effect of adding ethanol in the reaction system is extremely important. Ethanol will cause protein denaturation at a certain concentration, and it will release heat wh...
