Concentration device for aqueous protein solution

Abstract

The invention belongs to the technical field of bioengineering and provides a concentration device for an aqueous protein solution in order to solve the technical problem that a current aqueous protein solution is prone to causing scaling of tube nests in a concentration process. The concentration device comprises a tube nest heating tank, and is characterized by further comprising an evaporatingtank, wherein the inside of the tube nest heating tank is divided into a flash evaporation area, a heating area and a liquid material feeding area from top to bottom, a plurality of vertical tube nests are arranged in the tube nest heating tank, and the tube nests penetrate through the heating area to communicate the flash evaporation area with the liquid material feeding area; a first liquid inlet is formed in the tank wall of the liquid material feeding area; a liquid outlet is formed in the bottom of the evaporation tank; a second liquid inlet is formed in the tube wall close to the bottomof the evaporation tank and is higher than the heating area of the tube nest heating tank, and the second liquid inlet and the flash evaporation area of the tube nest heating tank are connected through a pipeline. With adoption of the concentration device, the tube nests are prevented from scaling, protein loss is reduced, and concentration efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and specifically refers to a concentration device for protein aqueous solution. Background technique [0002] Fish protease hydrolyzate, containing 5-15% protein, needs to be evaporated to remove water and concentrated to 50-70%. The usual evaporation methods, such as rising film or falling film evaporation, are heated in a tube heat exchanger. With the heating, the water in the protease hydrolyzate is continuously evaporated, so as to achieve the purpose of concentration. However, during use, it was found that since heating and evaporation are carried out in the tube heat exchanger at the same time, dry wall phenomenon occurs in the inner wall of the tube during evaporation and concentration, and the protein adheres to the inner wall of the tube, resulting in The walls gradually become clogged with scale. Therefore, the tubes in the heat exchanger need to be cleaned every once in a whil...
