Membrane separation technology is a separation technology widely used in solution separation, concentration and purification. It uses a membrane with selective permeation as a separation medium. The membrane wall is densely covered with micropores. The original solution passes through one side of the membrane under a certain pressure. The solvent and small molecular solutes penetrate the membrane wall as the filtrate, while the larger molecular solutes are retained by the membrane. , So as to achieve the purpose of material and concentration.

The main application areas are:

1. Concentration of tea powder, tea beverage and juice preparation.
2. Separation and concentration of animal and plant protein products.
3. Filtration and clarification of
