Concept of clean room - Aoshima System Engineering proposes energy conservation · CO2 reduction

Clean room for filling pharmaceutical cream

A clean room is a space to re-produce the value, we recognize as a means of production itself to yield profits based on the investment and social value of the company.

When installing the clean room, there are a several levels of detail to decide by the company's philosophy and strategic target of realistic production line.

The quality and level of the clean room should be decided in proportion to the philosophy and the strategy for the production.

So-called, from level 1, class 100, 1,000 to 10,000, and further more the concept of "clean booth zoning" which is not requested a cleanliness setting to isolate from the surrounding dirty zone.

The purpose of installing a clean room speaking in a word is to isolate products from pollutants (foreign objects) and take a decision of the cleanliness and the method according to the required quality by customers.

In addition, to ensure a high-quality, an investment and a profit, we will formulate an efficient flow line layout planning, an energy conservation designing and a utility planning, which are well-linked all together.

We will make a presentation about methods such as HACCP system for food safety, GMP system solution for pharmaceuticals, drying the solvent and a converting system solution with an appropriate adoption of hardware · control · software system and design concept for each line and each factory to meet various conditions.
HACCP system (Hazard Analysis and Critical Control Point)
GMP system (Good Manufacturing Practice)

What is the contaminant "foreign objects" is conceptually everything except products and all different things for products.

Among "foreign objects", Identify if acceptable material or not and also their state conditions, and decide the level and quality of the clean room.

In general the concept of "clean" is, not to let foreign objects enter the room nor propagate in there. If intrusion objects are detected, remove as soon as possible, which is the principle.

The contaminants, foreign objects, such as dust, fungi, insects, heat, moisture, solvents, bacteria, sweat, saliva, dust, paint, foreign objects created by the human body in general in the air, and also the product itself that was flowed out in the room, is extremely diverse and the amount is changing troublesomely in a discontinuous manner depending on the conditions.

Therefore, once a clean room stops its clean controlling operation, its function will turn to a dirt reproducing room.

Study of the layout · flow line · booth

• This study comes the first condition regardless food, pharmaceutical products and semiconductors, and the most important condition in consideration of productivity and efficient placement of the line.
• Building Standards Act regardless of the new construction and renovation, firefighting solution and health center response are taken into design condition at this point.
• Solvent dangerous goods solution, position zoning, and cleaning chemical solution for the room are taken into consideration at the same time.
• Working environment in the factory, neighborhood environment, and social environment response are al so taken into consideration.

Study of the air conditions

• To make decision of priority for the insect · dust proof cleanliness and zones.
• To make decision of identifying load for the generating source of heat, moisture and chemical: consideration of temperature and humidity conditions: and decision of year-round conditions
• Integration study of all-fresh system (all fresh air), circulating system, OA intake system and EA processing system
• Zone study of convection system, positive pressure, medium pressure and negative pressure
• Study of special conditions for the powder processing and chemical solution

Study of the clean booth and equipment solution

• Study of the booth
  • Zoning a clean room, pre-cleanroom, radiant heat, sensible heat, latent heat and a foreign objects occurrence area
  • Study of thermal insulation properties, non-thermal insulation properties, SUS ~ fluorine steel plate, non-combustible, fireproof and a standard specification
• Study of the filter
  • OA processing, pre-filter, mid-performance, HEPA, ULPA, heat-resisting specification
• Study of the air conditioning system
  • Heat source equipment, heat exchange equipment, air flow
  • Safety, efficiency, energy conservation, emergency response and durability
  • OA, EA, exhaust heat, dehumidification, dust removal
  • Instrumentation and control, software conditions
• Study of utility
  • Ducts, refrigerant, cold water, steam, drainage, power supply
  • Use a booth ceiling as a utility zone.
• Study of maintenance
  • Maintenance is the maximum function to keep and re-produce the quality of the clean room.
  • Study the method of the maintenance and maintenance space at designing stage.
• Study of the initial cost
  • Study of the low initial cost as a prerequisite of the purpose and quality
• Study of accessory devices
  • R structure floor - easy to wash and hard for the dust to retain
  • Coated floor specification corresponding Sanitary room, air shower, sheet shutter, dock shelter, medicine, oil, and warm water
  • Study of effective utilization means of the clean room and clean booth
