Problems solved by technology

[0007] (1) In the existing concentration technology, evaporation concentration with high concentration efficiency seriously damages the heat-sensitive functional and nutritional components in the material
[0008] (2) For relatively high-quality freeze-concentration, the conditions of freezing and low temperature require high energy consumption and long time for concentration. In addition, sterilization treatment is still required to store the finished concentrated juice for a long time.
[0009] (3) Concentration of single hydrate has limited bactericidal effect on materials, and sub-lethal microorganisms appear. Additional sterilizing treatment is required for long-term storage

Abstract

The invention relates to a concentrated solution manufacturing method based on CO2 phase change equilibrium regulation and a device for realizing the method. The method comprises the following steps: pre-cooling a liquid material, and controlling the temperature of an inner cavity of a concentration processor to be consistent with the pre-cooling temperature of the liquid material; the pre-cooled liquid material is fed into the concentration processor; cO2 is fed into an inner cavity of the concentration processor, the diameter of bubbles is regulated and controlled through a bubble generator, and the diameter of the bubbles ranges from 102 nm to 107 nm; after the pressure of the inner cavity of the concentration processor is 50-150 bar, stirring the liquid material, and maintaining the pressure of the inner cavity of the concentration processor at the same time; after the liquid material is stirred for a period of time, reducing the temperature of the inner cavity of the concentration processor to 0.5-10 DEG C, and regulating and controlling the pressure of the inner cavity of the concentration processor to 20-90 bar; the liquid material is subjected to a phase change crystallization reaction, and hydrate crystals and a concentrated solution are formed after the liquid material is subjected to a phase change stage and a crystal growth stage.

Description

technical field [0001] The invention relates to the technical field of concentrated liquid materials in the fields of biopharmaceuticals, food, chemical synthesis, etc., in particular to a CO-based 2 A concentrated solution manufacturing device controlled by phase transition equilibrium and a CO-based 2 A method for producing a concentrated liquid controlled by phase transition equilibrium. Background technique [0002] As a semi-finished product or product, concentrates are widely circulated in the fields of biopharmaceuticals and food processing. Efficient, high-quality, and low-cost concentration methods have always been an urgent need for the concentration industry. [0003] Concentration by hydrate method is a concentration method in which the water molecules of the guest gas and the main water molecules in the solution form a cage-like structure similar to ice crystals under a certain pressure and temperature. After solid-liquid separation, the concentrated solution i...
