What Clean Equipment Is Needed for A Food Clean Room? What Are Their Functions?

Clean rooms have become an inevitable part of modern food processing plants so as to maintain safety and hygiene of the products. But in constructing clean rooms, it usually happens that a company may only pay attention to the air conditioning purification tools and the level of cleanliness, but not along with the supporting of the Cleanroom Equipment in the clean rooms. As a matter of fact, the clean equipment will be scientifically and reasonably installed directly by influencing whether the clean room environment can indeed meet the design standards and whether its long-period operation can be stable.

So, what special equipment does a food clean room need? What functions do they each have? Today we will comprehensively sort out the list of clean equipment and their functions that must be equipped in a standard food clean workshop.

Why must food clean rooms be equipped with clean equipment?

When performing food processing, entry of personnel and their exit, flow of materials, replacement of tools and equipments maintenances will now prove to be a source of pollution. Although the cleanroom air conditioning system is rationally constructed, it may happen that without a good clean equipment the pollution source cannot be fully blocked and guarantee the food safety.

As an auxiliary protection system for clean environments, Cleanroom Equipment's main functions are:

• Isolate and remove dust and bacteria carried by personnel and materials

• Maintain a stable positive air pressure inside the cleanroom

• Avoid backflow of air pollution in non-clean areas

• Reduce the risk of cross-contamination and separate different process areas

Therefore, selecting high-quality and scientifically laid out clean equipment can effectively extend the life of the HEPA filter, reduce the air conditioning load, and reduce the operating costs of the cleanroom.

Commonly used cleanroom equipment configuration list for food cleanrooms

1. Air Shower Room

Function

Before personnel or materials enter the cleanroom, high-speed clean airflow (≥25m/s) is used to blow away dust and microorganisms attached to the surface of clothing and objects, effectively blocking the pollution source from entering the clean environment.

Classification

• Single person single blowing

• Single person double blowing

• Double person double blowing

• Three people double blowing

• Cargo air shower room

Advantages

It has high dust removal efficiency, does not cross contaminate, can be tailored to a variety of specifications and sizes, and can adapt to the traffic needs of the different workshops. UV sterilization, automatic sensing, and double door interlocking functions are also provided on some equipment to improve the user experience and clean control effect.

2. Pass Through Box

Function

When materials, tools, and food raw materials are transferred between the clean area and the non-clean area, the double-door interlocking structure effectively blocks air convection and prevents air pollutants from entering the clean room.

Classification

• Clean Pass Box

• Air Shower Pass Box

• Laminar Pass Box

Features

Easy to operate, compact structure, small footprint, can be flexibly arranged in the wall or partition, often equipped with electronic interlocking, mechanical interlocking, indicator light, and ultraviolet sterilization device.

3.HEPA Box

Function

Evenly deliver the highly clean air filtered by the air conditioning purification system into the clean room to form a clean airflow, ensuring that the dust particles and bacteria concentrations in the clean room meet the standards.

Features

• High-efficiency HEPA filter filtration efficiency ≥ 99.99%

• Even wind speed, low noise

• Detachable structure, easy to replace the filter

Common layout

Ceiling-type air outlet, suitable for workshops of different cleanliness levels, ISO 5-ISO 8 are applicable.

4. Clean workbench

Function

Provide separate air purification protection for local high-cleanliness operating environment, such as food ingredient weighing, sensitive packaging, semi-finished product packaging, etc.

Features

• Horizontal or vertical HEPA air supply

• Independent fan system, ISO 5 cleanliness of operating area

• Splash shield design to ensure safe operation

• Built-in UV sterilizer to reduce microbial contamination

5.Clean Storage Cabinet

Function

Store clean work clothes, masks, hats, dustproof shoes and other items to prevent clean supplies from being contaminated again during storage.

Features

• 304 stainless steel material, smooth and corrosion-resistant

• Built-in high-efficiency air outlet to maintain positive pressure in the cabinet

• Ultraviolet sterilization lamp, timed sterilization

• With shelves, hooks, and shoe racks for easy classification and storage

6. Fan Filter Unit

Function

Assists in air purification in local areas of clean rooms, suitable for filling tables, packaging areas, and above sensitive material operation tables, to quickly reduce local dust concentration.

Features

• Mobile or fixed installation

• HEPA+ pre-filter combination

• Adjustable wind speed, local cleanliness ISO 5-7

Conclusion

The cleanroom equipment that is used in food cleanrooms, such as Air Shower Room, Pass Through Box, etc., is not only an important guarantee for achieving the cleanliness level, but also an effective means to prevent food contamination, extend equipment life, and reduce operating costs.
