Food & Pharmaceutical Packaging Purification Workshop Floor Plan

The architectural layout of the purification engineering should fall under the professional scope of architecture. However, due to the requirement of personnel and material segregation in food-grade cleanrooms, and maintaining the static pressure gradient in each purification workshop's clean operation area, the architectural layout of this purification project should possess the following points:

1. Each purification operation room in the purification project is centrally equipped with an independent antechamber as an airlock. The airlock is simultaneously connected to all operation rooms, ensuring that air from the low cleanliness area does not infiltrate into the high cleanliness area.

2. Employees in the clean room change into attire and shoes in the locker room, wash hands in the washroom, pass through the anteroom, air shower room, and into various operation rooms.

3. Logistics in the cleanroom pass through an external corridor, are disinfected via a mechanical interlock in the pass-through decontamination window, then enter the buffer corridor, and finally proceed to the individual operation rooms in the dust-free cleanroom through another pass-through window.

The personnel in the clean room pass through the dressing room to change and put on shoes → wash hands in the cleaning room → buffer room → air shower room → various operation rooms

Food & Pharmaceutical Packaging Cleanroom Structure Description:

In accordance with the "Clean Room Design Code," the walls and ceilings of the workshop must be constructed with dust-free, non-dust-retaining, smooth surface materials, and dead corners must be avoided within the workshop. Specialized clean room construction panels should be used to enhance the lifespan of the clean room and achieve an aesthetically pleasing appearance. All aluminum materials must be selected for their quality.

Food Packaging Cleanroom Floor Plan

The ground is made of solvent-based epoxy resin, featuring a dense surface with no sanding, hollowing, or cracking. The colors are vibrant, and the antistatic performance remains constant. It can bear moderate loads and withstand high temperatures. In addition to meeting usage requirements, it also serves as a decorative element. It is wear-resistant, washable, dustproof, and slip-resistant, with excellent performance and uniform color and luster.

Ventilation and Air Purification Equipment Solutions:

The dust-free workshop is designed in accordance with specifications, featuring a return air system. The machine room is located on the side of the factory building, based on the actual conditions. A unitary purification system can be used, eliminating the need for a separate machine room. The return air and supply air ducts are connected to the air conditioning units within the technical interlayer. The supply and return air ducts are made of high-quality galvanized steel plates, connected with flexible connections through air valves, and the galvanized steel ducts are manufactured on-site.

Food Packaging Cleanroom Lighting Solution:

The clean room of the purification workshop should use suspended ceiling purification lamps, while the non-clean areas should use standard fluorescent lights. The lighting design for each room should be controlled independently with UV lamps, all of which are controlled by an electrical control box and centrally managed by the main distribution panel. Indoor lighting should use sealed lighting units, and all power outlets should be flush-mounted. There should be no exposed wiring in the purification engineering, purification sandwich panels, purification air conditioning, dust-free workshop purification, and ventilation ducts.

Food & Pharmaceutical Packaging Cleanroom Floor Plan

Food and pharmaceutical packaging factory cleanroom floors commonly use self-leveling epoxy resin floors with good hardness, impact resistance, strong adhesion, low dust generation, and resistance to hot water, acid, and alkali corrosion to enhance cleanliness and achieve a smooth, bright appearance.

Cleanroom Air Conditioning System for Purification Plant

High-purity areas are confined to the vicinity of the equipment, utilizing local purification techniques such as laminar flow, dust extraction, and dehumidification to alleviate the load on clean air conditioning systems, thereby achieving energy-saving objectives.

Using VFD technology in air purification HVAC systems can save energy. Not only does the system maintain a relatively constant airflow, but room pressure remains stable as well. Additionally, the fan starts smoothly while meeting the on-duty ventilation requirements.

Food packaging workshop guidelines require:

The food packaging clean room is equipped with sufficient air supply volume, enough to dilute or eliminate indoor pollution.

2. The air in the dust-free food packaging workshop flows from the clean area to the less clean areas, with the flow of contaminated air reaching a low level. The air flow direction at the entrance and within the indoor structure is correct.

3. The supply air in a food packaging dust-free room will not significantly increase indoor contamination.

4. The movement of indoor air in the dust-free workshop for food packaging ensures there are no high-concentration accumulation areas within the cleanroom.

Food & Pharmaceutical Packaging Workshop Inspection Standards:

Airflow Rate: Supply and Exhaust

If it's a turbulent cleanroom, measure its supply and exhaust air volumes. For a unidirectional airflow cleanroom, measure the air velocity.

2. Airflow control between zones:

To verify the correct airflow direction between different zones in the purification workshop, which is from the clean area to the area with lower cleanliness, it is necessary to inspect:

A. Filter Leak Testing: Inspect the high-efficiency filter and its frame to ensure that suspended pollutants do not pass through.

B. Isolation Leak Test: This test is to demonstrate that suspended particulate matter does not penetrate through building materials to enter the cleanroom.

C. Cleanroom Indoor Airflow Control: The type of airflow control testing depends on the air pattern of the cleanroom—whether it is turbulent or unidirectional. If the cleanroom airflow is turbulent, it must be verified that there are no areas with insufficient airflow within the dust-free workshop. For a unidirectional airflow cleanroom, it must be confirmed that the entire room's wind speed and direction meet the design requirements.

D. Suspended Particle Concentration and Microbial Concentration: If the aforementioned tests meet the requirements, measure the particle concentration and microbial concentration (if necessary) to verify their compliance with the technical requirements of the cleanroom design for dust-free workshops.

3. Additional Tests:

In addition to the aforementioned pollution control tests, it may sometimes be necessary to conduct one or more of the following tests: (temperature, relative humidity, indoor heating and cooling capacity, noise levels, illumination, vibration values).

Food & Pharmaceutical Packaging Workshop Cleanroom Grade Selection:

1. The cleanroom engineering for food and pharmaceutical packaging factories primarily reflects the product's environmental conditions in terms of temperature and humidity, as well as the count of fine dust particles, which plays a crucial role in product quality and pass rate. In the packaging industry, this is mainly reflected in the two aspects of food packaging and pharmaceutical packaging, focusing on the environmental conditions of temperature and humidity in dust-free cleanrooms, the count of fine dust particles in the air, and the quality of water.

2. Includes cleanrooms for food and pharmaceutical packaging facilities, ranging from 100,000-class, 10,000-class, 1,000-class, 100-class, to food packaging cleanrooms.
