According to the national regulations on food and beverage production licenses, the clean room environment of food and beverage workshops and laboratories is controlled to reach the air purification standard of 10,000 or 100,000. It is best to isolate the aseptic clean workshop from the outside world and cannot pass through or be affected by other factors. interference. Food safety issues and medical drugs have always been hot topics of great concern to the society. How to achieve safe, reliable, high-quality pharmaceutical and food mass production? Aseptic design of food and medical clean room is particularly important.

I.SC certification requirements for 100,000-level purification projects in food workshops

1.Clean air grade (ISO grading standard) Food industry grading standard

2.The filling room is ISO grade 4

3.ISO grade 5 of the inner packaging material storage room

4.Personnel clean room ISO level 7

II.Production zoning of quasi-clean areas in food laboratories and production workshops

1.Clean production area refers to the operation area of the processing and conditioning plant whose cleanliness requirements are inferior to that of the clean production area. include:

① Food processing and conditioning farms such as cutting, grinding, mixing, blending, shaping, shaping, cooking and extraction, improving food characteristics or preservation (such as oil extraction, starch separation, bean paste manufacturing, emulsification, coagulation or fermentation, sterilization, Freezing or drying, etc.) processing and production places)

② Preparation room for inner packaging materials (refers to the operation place where the inner packaging materials can be used directly without any cleaning and disinfection procedures, and the outer packaging or forming operations are carried out).

③ Buffer room: When raw materials or semi-finished products directly enter the controlled production area without going through the normal manufacturing process, in order to avoid direct communication between the controlled production area and the outside world, a buffer place set at the entrance.

III,the construction layout and decoration process of the sterile room of the food laboratory

Clean room sterile design is widely used in microbiology, biomedicine, biochemistry, animal experiments, genetic recombination and biological products and other high-demand laboratory places. In the microbiology laboratory and related work, the inoculation and transplantation of bacterial species is an important operation. In this process, to ensure that the bacterial species are pure and pollution-free, it is necessary to pass a sterile laboratory that meets a certain air cleanliness level and experimental environment requirements. Therefore, the sterile room is also called the inoculation room, which is a dedicated laboratory for aseptic operations such as systematic inoculation and purification of bacteria.

1) Clean room aseptic design layout

The sterile laboratory is mainly composed of six parts, namely: preparation room, washing room, sterilization room, sterile room, constant temperature culture room, and ordinary laboratory. The outer room of the sterile room should be equipped with a buffer room. The area of all rooms should not be too large, and the ceiling should not be too high to facilitate air sterilization. The main layout requirements of a sterile laboratory are as follows:

1.The entrance avoids the corridor and is located in the bacteria inspection operation room;

2.Separate from the operating room with two buffers;

3.Both the sterile room and the buffer room must be equipped with UV lamps. It is required to install a 30W UV lamp every 3 square meters;

4.In the sterile room, there is a center of the experiment table (both the experiment table and the side table are acceptable), and the distance between the ultraviolet lamp and the experiment table should be less than 1.5m;

5.There are double windows between the sterile room and the operating room to form a small passage. The following is the CEIDI brand delivery window in use:

2) Aseptic room decoration process

Ceidi experience: To achieve aseptic clean room, design standards and on-site construction techniques are equally important. After more than ten years of deep cultivation in industrial decoration, we have summarized the following decoration process experience for everyone:

1. Reduce corners and cracks: In an ISO5 clean room, the number of bacteria cannot exceed the US cubic feet of 0.1 CFU, including the joints between walls and between walls and ceilings. As far as this problem is concerned, the common solution is to use a curved corner on these links. This requires equipment and accessories to be integrated smoothly.

2. Modular clean room: With the development trend of modular clean plant, we have higher requirements for product line, capacity and regional flexibility. Once the contact frame is set up, the pipeline system, air conditioning system, fire alarm system, automation, control system, doors and windows, and the ground can be processed. And these will be customized according to the customer's detailed design.

3. Reduce the generation of air particles: This is related to the surface coating materials of the clean room. Our goal is to select a material that can meet the chemical resistance requirements and does not produce exhaust gas or particulates.

Master Kong Holdings Limited and its subsidiaries are principally engaged in the production and sale of instant noodles, beverages and instant foods in China. The group began to produce instant noodles in 1992 and expanded its business to instant foods and beverages since 1996. In March 2012, the group further expanded its beverage business scope and completed its strategic alliance with PepsiCo China’s beverage business, and began to be solely responsible for manufacturing and filling. Packing, packaging, sales and distribution of PepsiCo's non-alcoholic beverages in China. At present, the three major products of Master Kong Group have occupied a significant market position in the Chinese food market. Our company provides design, construction, material and after-sale services for Master Kong’s laboratories, clean rooms, production workshops, and company facades. The technical indicators of environmental control projects (temperature, humidity, cleanliness) fully meet the company’s specifications Requirements, and passed the company’s strict engineering acceptance, and won the company’s praise and praise. The project area is 7,800 square meters.

The above is about the decoration design plan of the food aseptic laboratory.
