The production process of regular instant coffee powder generally includes pretreatment, roasting, grinding, extraction, separation and purification, concentration, and drying. Conventional production processes often use disc separators for the separation and purification of coffee extract, followed by thermal concentration. Although high-speed disc separators can remove most insoluble substances from the solution, some insoluble materials remain in the product, resulting in sediment when brewing coffee, which degrades the product's taste. Additionally, subsequent thermal concentration, due to high temperatures, easily causes the decomposition and volatilization of aromatic compounds in coffee, leading to a decline in product flavor.

       Leveraging years of practical experience serving instant coffee production companies and its own advantages in membrane separation technology, Xihe Fluid Technology has successfully applied membrane separation technology to the instant coffee production process. Utilizing the precision retention function of membranes, insoluble substances in coffee extract are effectively separated. The low-temperature concentration capability of membranes ensures the complete preservation of product flavor during the concentration process. This approach offers technical advantages such as low energy consumption, high coffee quality (high purity, better dispersibility, high clarity, excellent taste), and a high degree of automation.

       Advantages of Membrane Separation Technology in Instant Coffee:
        ① Advanced membrane separation technology utilizes the precision retention function of membranes to achieve separation, purification, and low-temperature concentration effects;
        ② Pure physical operation at room temperature, no chemical reactions, preserving heat-sensitive components and overall flavor;
        ③ Advanced modular design allows for easy replacement of filter materials and simple operation;
        ④ Equipped with online regeneration cleaning and discharge devices, reducing labor intensity and production costs while improving efficiency;
        ⑤ Membrane elements use imported filter membranes with various certifications, ensuring long service life and safety;
        ⑥ The entire equipment is made of sanitary-grade materials, complying with GMP certification.
