An ISO compliant coffee production line is a set of production equipment and processes that meet the requirements of the International Organization for Standardization (ISO) standards, which is used to produce high quality coffee products. It usually includes several key links, such as coffee bean transportation, weighing, cleaning, roasting, bean breaking, extraction, evaporation, aroma treatment, spray drying, and packaging. Firstly, the transportation of coffee beans needs to ensure that the beans are not damaged and are stored in a suitable environment to prevent mildew and insect infestation. Accurate weighing is the basis for ensuring the consistency of product quality, and high precision weighing equipment is used to ensure that each batch of coffee beans is in the correct proportion. The cleaning process can remove impurities and dust on the surface of coffee beans, improving the purity of the product. Roasting is a crucial step in determining the flavor of coffee. Different roasting degrees will endow coffee with different flavor characteristics, such as light roasted coffee has a fresh and acidic taste, while dark roasted coffee has a stronger bitterness and a rich aroma. Advanced roasting equipment can accurately control the roasting temperature and time to ensure the stability of the roasting effect. After roasting, the coffee beans are broken, and then extracted to obtain coffee liquid. The evaporation and aroma treatment processes can concentrate the coffee liquid and retain the unique aroma of coffee. Spray drying is often used in the production of instant coffee powder, which can quickly dry the coffee liquid into powder form. Finally, the packaging link needs to ensure the hermeticity and hygiene of coffee products. According to different product forms, such as canned coffee, bag packed coffee powder, or single serve coffee capsules, different packaging methods and materials are selected. Complying with ISO standards means that in the entire production process, strict control is exercised over various parameters, including raw material quality, production environment hygiene, equipment operation specifications, and product quality inspection, to ensure the stability and reliability of coffee products, and to meet the quality and safety requirements of consumers in different regions.
