Description

Technical Field

[0001] The utility model relates to the technical field of lactase impurity removal and concentration, in particular to a low-concentration lactase impurity removal and concentration device. Background Art

[0002] Lactase is a digestive enzyme in the human body. Its main function is to break down lactose into galactose and glucose that can be absorbed by the human body. Lactase is mainly produced by the small intestinal mucosal cells. For infants and young children who rely on breast milk or milk powder as their main source of nutrition, it is the most important digestive enzyme in the body. When the human body lacks lactase, lactose cannot be effectively broken down, which may lead to lactose digestion and absorption disorders, causing abdominal pain, flatulence, diarrhea and other indigestion symptoms. This condition is called lactose intolerance.

[0003] In the production process of lactase, low-concentration lactase needs to be removed and concentrated. Since lactase is a heat-sensitive substance, it is easy to deteriorate at high temperature, affecting the activity of the enzyme. Therefore, lactase is separated, concentrated and purified at room temperature, which can be achieved through membrane separation technology. Compared with traditional separation methods, membrane separation technology has low energy consumption and is easy to operate. Membrane separation equipment can save costs and does not require the addition of inorganic salts and organic solvents. In the membrane separation process, membrane concentration intercepts the enzyme based on the principle of molecular sieves, allowing small molecular impurities and water to pass through. Therefore, in the concentration process, the inorganic salts and small molecular nutrients in the fermentation broth can be effectively removed, and the enzyme can be purified, thereby improving the quality of the enzyme preparation.

[0004] Before concentrating the low-concentration lactase through membrane separation technology, it is necessary to carry out preliminary impurity removal for the low-concentration lactase. This process requires the use of filter membranes or filter papers with different pore sizes to filter according to the size and shape of the substance to remove tiny particles and suspended matter in the solution. During the preliminary impurity removal process of the common concentration lactase, the filter holes are easily clogged, resulting in low impurity removal efficiency, and it is difficult to replace or clean the filter device. In view of this, the present application proposes a low-concentration lactase impurity removal and concentration device. Utility Model Content
