Food factories are concerned with the quality and safety of food, and even affect the health and life of consumers. They involve many professional knowledge such as food science and engineering, including food factory graphic design, process design, auxiliary facility design, architectural design, decoration construction, etc. content.

According to national production standards, food plants need to reach 100,000 air purification standards. What is a 100,000-class clean workshop? In short, the number of particles per cubic meter of air in the workshop is ≥0.5μm, and the number of particles is less than 3.52 million. The less the number of particles in the air, the less the amount of dust and microorganisms. The cleaner the more. The 100,000-class cleanroom requires 15-19 breaths per hour. After the air exchange is completed, the air purification time does not exceed 40 minutes.

 

Food factory cleanrooms can be divided into four grades:

Class I, clean operating area, with high risk of pollution;
Class II, the background environment in which the A-level zone is located, or the pollution risk is second only to the Class I clean operation area involving non-zui terminally sterilized food;
Class III, a clean operating area of lower importance in the production process;
Class IV, which is the area of general cleaning requirements for the pre-process.
When there is no special requirement for temperature and humidity in the production process, the temperature of Class I and Class II clean workshops should be 20 °C - 25 °C, the relative humidity should be 30 °C - 65 °C, and the temperature of Class III and Class IV clean workshops should be 18 °C. -26 ° C, the relative humidity should be 30% -70%.
The number of air changes in static rooms of different levels should be determined according to the number of personnel, area size, operating intensity, etc., or according to the corresponding standards. The fresh air volume should be designed to be no less than 40 m3/h per person, meeting the need for ventilation and maintaining positive pressure.

 

One of the important functions of the food factory clean factory is to ensure that the food produced is free from pollution and contains no harmful bacteria. In order to achieve this function, the following points should be fully considered when decorating:

1. Is it consistent with the SC certification?
Food factory clean factory oil has certification requirements, so design should be fully considered. The key is the overall layout, how to allocate manpower and logistics, how to distribute lettuce and cooked food, etc. The good way is to ask professionals to help audit.
2, decoration investment
Considering how much money should be invested in the renovation of a clean factory to obtain SC certification. Budget costs should include partitions, ceilings, equipment and floors. For partitions and ceiling decoration, color steel plates should be the main cost. The floor decoration can be epoxy resin type, cement type, diamond type, many food factories will be solidified, and the aseptic workshop will use PVC or epoxy resin.
3. Consider operating costs
The operating costs to be considered in the renovation mainly include power, technology, and wiring. The operation of the power mainly depends on the power of the decoration equipment and high-power equipment. Of course, it will consume more power after being put into operation. The power should be selected according to actual needs. Save money.
Then, in terms of process and circuit, different processes will have different production and transportation modes. These differences will also lead to different operating costs, and the use of lines, electrical, etc., if it is easy to maintain, can also save costs.
