Clean rooms for food processing
Standard Tech offers turnkey Steril-Tech® clean rooms for any food and pharmaceutical industry. Sized in compliance with ISO 14644-1:2015 and FS209 standards, they are built with entirely sanitisable Isostandard® wall panelling and ceilings. Stainless steel doors with special seals guarantee pressure, are equipped with traffic light or interlocked access, and have viewing windows installed flush with the wall in material certified for contact with foodstuffs.
Based on the kind of filtration required, the type of filters to be installed and the potential of the machines is chosen; the filters are positioned progressively so that the lower efficiency ones are protected by the higher efficiency ones (the absolute filters, for example), preserving their life and deterioration. The systems are managed by entirely washable air treatment units, which are suitable to deal with temperature, relative humidity (with low values for greater health), controllable air velocity and, above all, the pressure control system to avoid the penetration of potential external polluting agents.
Based on production line requirements, the air flows are:
- vertical unidirectional (particularly recommended for ready-sliced salami lines), in which the absolute filters are housed on a hood to concentrate the flow of outgoing clean air, and the air intake grids are located on the low parts of the room. In a pharmaceutical or hospital environment, laminar flow is guaranteed by a special stainless steel diffuser located directly above the operator.
- non-unidirectional, in which the sanitised working area is the entire production department, without the air flows being concentrated in a specific work area.
Particular attention regarding the size of a clean room is paid to access by operators and primary packaging materials, which must pass through specific rooms of reduced size fitted with specific air showers, in order to prevent direct access to the clean room.
The control parameters are managed by totally customisable PLCs connected to the Control-Tech 3000® remote assistance network and the air treatment units are equipped with sensors to detect filter clogging, which promptly indicate when they have to be replaced.
