Instant Coffee Liquid Concentrate Membrane Purification Concentration System

       The production of instant coffee powder generally involves processes such as coffee bean selection, cleaning, roasting, grinding, extraction, filtration, concentration, drying, and sterilization. For liquid coffee preparation, the process stops at the concentration stage. Extraction is commonly done using water extraction or cold brew extraction, both aimed at separating components like coffee sugars from the powder as much as possible to improve yield.

      Chongqing Jiahe Filtration Technology Co., Ltd. has long been committed to the development and application of instant food production equipment. The designed and manufactured low-temperature membrane process for coffee production offers technical advantages such as low energy consumption and high coffee quality (high purity, good dispersibility, and high clarity). The pilot line equipment configuration for coffee production is as follows: single batch input of 25-30kg, water-to-coffee ratio of 1:8 or 1:10 for two extraction cycles, two batches per day processing 50-60kg of coffee beans, extraction tank effective volume of 300L, equipped with stirring and steam heating. Total extract volume is about 1200L, with subsequent centrifugal equipment, membrane filtration equipment, and membrane concentration equipment selected for 200-300L/h, accompanied by a 500L/h primary purified water system for extraction water, electric steam generator water, and equipment cleaning water.

Advantages of Coffee Membrane Filtration and Concentration:

（1）The selection of membrane filtration precision is perfectly suited for the purification and refinement of coffee, allowing effective components to pass through while retaining dissolved and semi-dissolved macromolecular impurities that cause low clarity and poor dispersibility.

（2）Membrane filtration and concentration are room-temperature physical processes, maximizing the preservation of coffee aroma and ensuring high product quality.

（3）Membrane concentration technology employs a cross-flow operation process, offering high separation efficiency and low manual labor intensity.

（4）Membrane concentration technology is solely driven by electricity, with a cost of 15-20 RMB per ton of water removed during concentration.

（5）Membrane concentration technology can concentrate components up to 15%, significantly reducing the volume for subsequent freeze-drying, thus saving energy and reducing consumption.

（6）Membrane concentration systems are made from sanitary-grade stainless steel materials, complying with QS and GMP requirements.

（7）Membrane filtration and concentration systems are designed with online regeneration cleaning and discharge devices, making equipment cleaning and maintenance simple.
