Food Daily Chemical Purification Project

Food industry clean room (area) is the application of a clean technology for raw material processing and deep processing production in the food industry. In addition to controlling particulates in the air, clean rooms in the food industry also strictly control microorganisms in the air environment, and technically prevent cross-contamination of food by microorganisms. The most representative of these are aseptic packaging, aseptic packaging of food (such as flexible packaging of fresh fruit juice, milk, etc.), which is a packaging process completed in a clean environment, which is greatly superior in maintaining food color, aroma, taste, nutrition, etc Canned food for general high temperature sterilization. In addition to aseptic packaging, air cleansing technology also has a high application in food brewing and fermentation.

In addition to aseptic packaging, air cleansing technology also has a high application in food brewing and fermentation.

The cleanliness level of the food industry clean room (area) refers to the pharmaceutical industry clean room, but it is higher than the general clean room. According to the original US federal standard FS 209B, which has been discontinued, it can be divided into 100 and 1000. , 10000, 100,000, and 3000000 levels. According to the Chinese national standard GB-50073, which is in line with ISO-14644, which is an international standard, there are 1-9 levels. The original 100, 1000, 10,000, and 100,000 levels were all managed by The international standard ISO-14644 replaces Class 5, Class 6, Class 7 and Class 8. These clean rooms (areas) have Class 1-8 cleanliness, of which Class 1-5, the airflow pattern is unidirectional Flow or mixed flow, wind speed 0.2-0.45m / s; 6-level airflow pattern is non-unidirectional flow, the number of air changes is 50-60 times / h; 7-level airflow pattern is non-unidirectional flow, the number of air changes is 15- 25 times / h; 8-9 level airflow pattern is non-unidirectional, and the air exchange times are 10-15 times / h.

Our company also has corresponding design and construction plans for such clean rooms, and has a professional design team and a professional construction team.


In this type of clean room, we pay more attention to hygiene and safety. Our company uses non-toxic, light-colored, waterproof, mildew-proof, non-shedding, easy-to-clean materials for the walls, ceilings, doors, and windows in the workshop. It should have radian (curvature radius should not be less than 3cm); the operating table, conveyor belt, transport vehicle, and tools in the workshop are made of non-toxic, corrosion-resistant, non-rust, easy-to-clean and disinfect, solid materials. The clean room that can be completed can create value for customers. This type of clean room has a lot of recoverable energy such as waste heat. From the past engineering technology applications, there are many energy saving aspects for this type of clean room permanent clean engineering company. Measures plan.

       Daily chemical products are produced by combining daily chemical raw materials. Chemical raw material production workshops have extremely important requirements for air purification. Chemical raw materials have played a significant role in the daily chemical industry. Such clean room workshops require the production of cosmetics during the production process. Dust or products using harmful, flammable and explosive raw materials must use a separate production workshop. The floor of the workshop floor should be flat, wear-resistant, non-slip, non-toxic, and impervious to water to facilitate cleaning and disinfection. The floor of the work area that needs to be cleaned should have a slope without water accumulation, and a clean floor drain should be set at the lowest place. The height of the air inlet from the ground is not less than 2 meters, and there must be no pollution source nearby. For UV disinfection, the intensity of the UV disinfection lamp should not be less than 70 microwatts / cm2, and whether the temperature and relative humidity of the clean room (area) should be set according to the requirements of the production process of cosmetics in accordance with 30W / 10m2. There are no special requirements. Whether the temperature is controlled at 18-26 ℃ and the relative humidity is controlled at 45% -65%. The cleanliness level of this type of clean room is also 1-9, and the airflow organization forms are unidirectional flow, non-unidirectional flow, mixed and divided flow, and vector flow. Different airflow organizations are selected according to the situation of the workshop and the production process requirements. Among them, the 1-5 level air flow pattern is unidirectional flow or mixed flow, the wind speed is 0.2-0.45m / s; the 6 level air flow pattern is non-unidirectional flow, and the number of air changes is 50-60 times / h; the 7 level air flow pattern For non-unidirectional flow, the number of air changes is 15-25 times / h; for the 8-9 level air flow pattern, non-unidirectional flow is 10-15 times / h.

Such clean rooms have a relatively large workshop area, and some chemical substances are produced during the production process. 都是采取比较节能的设计方案。 For our company to adopt an on-site solution in the design of the air purification system, some emissions can also be used for energy recovery. For such clean room permanent cleaning engineering companies, a more energy-efficient design scheme is adopted.
