1、 Selection of filter media

Food grade safety: The filtering medium must meet the national food safety requirements, which means it must be food grade and cannot cause any form of contamination to the food. This requires that the filter media comply with relevant hygiene standards during production, processing, storage, and use.

Appropriate filtration efficiency: The filtration medium should have sufficient filtration pore size and surface area to effectively remove solid particles, impurities, and microorganisms from liquids or gases. The filtration efficiency should match the specific requirements of food processing to ensure that the filtered food meets quality standards.

High temperature and chemical resistance: In some food processing processes, high temperature or chemical treatment may be required. Therefore, the filter media should have good high temperature and chemical resistance to ensure stability and filtration efficiency under these conditions.

2、 Control of the filtration process

Aseptic operation: In the process of food filtration, aseptic operation should be strictly controlled to avoid microbial contamination. This includes cleaning and disinfection of filtration equipment, regular replacement of filtration media, and sterile control of the filtration environment.

Stable filtration pressure: Maintaining a stable filtration pressure helps ensure the smooth progress of the filtration process, avoiding a decrease in filtration efficiency or contamination of the filtrate caused by the filter cake being too tight or too loose.

Reasonable filtration time: Based on the actual situation of food processing and the characteristics of the filtration medium, arrange the filtration time reasonably to ensure the filtration effect and improve production efficiency.

3、 Selection and maintenance of filtering equipment

Equipment hygiene: Filtering equipment should have good hygiene, be easy to clean and disinfect, to prevent food contamination.

Equipment stability: The filtering equipment should have stable operating performance and be able to maintain efficient filtering effect for a long time.

Regular maintenance: Regularly maintain and inspect the filtering equipment to ensure that it is in good working condition. At the same time, replace damaged or expired filter media in a timely manner to ensure filtration efficiency.

4、 Other requirements

Environmental friendliness: The waste and wastewater generated during the food filtration process should be properly treated to meet environmental requirements.

Economy: While ensuring the filtering effect, try to reduce the filtering cost as much as possible and improve economic benefits.

Above, food filtration requires strict adherence to a series of requirements during food processing to ensure the safety and quality of food. These requirements cover the selection of filter media, control of the filtration process, selection and maintenance of filtration equipment, and other related aspects.
