Membrane separation technology for filtration of mulberry wine

Mulberry wine is brewed from mulberries, which have the effects of nourishing the liver and kidneys, generating fluids and moistening the intestines, delaying aging, blackening hair and improving vision, and enhancing immunity. Therefore, mulberry wine and mulberry vinegar are loved by people. However, problems were encountered in the production of alcohol. Due to the low filtration accuracy of traditional filtration methods, impurities such as pectin, protein, and plant fibers cannot be completely intercepted, and secondary precipitation may occur after prolonged storage. So, what filtering method should be chosen for mulberry wine?

Membrane separation technology, as a new type of separation technology, has the advantages of efficient separation, simple equipment, energy saving, room temperature operation, and no pollution. It is widely used in the industrial field, especially in the fields of food, medicine, and biochemistry, where it is developing rapidly.

Membrane separation technology has the following characteristics:

1) The membrane separation process does not undergo phase changes, therefore membrane separation technology is an energy-saving technology;

2) The membrane separation process is driven by pressure and carried out at room temperature, which is particularly suitable for the separation, concentration, and refining of thermosensitive substances such as enzymes, fruit juice, and certain drugs.

3) Membrane separation technology has a wide range of applications for separation, from particle level to microbial cells, and even ion level. The key is to choose different membrane types;

4) Membrane separation technology uses pressure difference as the driving force, so it adopts a simple device and is easy to operate.

By using membrane separation technology and combining with the characteristics of material products, different pore sizes and structures of separation membranes are selected based on the molecular weight, molecular structure, product temperature, product concentration, viscosity, etc. of effective flavor substances, components, and impurities. Different operating parameters are chosen to achieve the same filtration and separation effect for different products. By using the selective screening principle of membranes, large molecular impurities are intercepted, allowing effective ingredients and flavor substances in the product to pass through, thereby improving product quality.

Advantages of Mulberry Wine Clarification Membrane Separation Equipment:

1. High quality nanotechnology materials, with a membrane pore size of 1000Da-50nm, thoroughly separate large molecular impurities that are not visible to the naked eye. The filtrate is clear and has high transparency, and does not become turbid after long-term storage, without secondary precipitation;

2. The feed liquid operates in a cross flow mode without the need for filter aids, which can solve pollution blockage;

3. Pure physical operation at room temperature, without chemical reactions, without damaging thermosensitive components and affecting the flavor of the wine;

4. Professional modular design, easy replacement of filter materials, and simple operation;

5. Design online regeneration cleaning and sewage discharge devices to reduce labor intensity and production costs, and improve production efficiency;

6. Select 304 or 316L stainless steel sanitary grade materials that meet QS and GMP requirements.
