Monofan (STERISTEAM) Static with Air/Steam process

The process is in fact rather old and well-known.

As the water used to cool the products is mixed with steam condensates (containing chemical components coming from the boiler), it must be rejected and changed each cycle. The process must be used carefully in a nature protective policy. In France and some other countries, this process is less interesting as the cooling must now be made through an heat exchanger (no more lost water cooling is allowed). Cooling can be made with a cascading water system (a Bi process STERIFLOW) or with dry air cycle (very long time, special for pharmaceutical industry).

Main characteristics

-          Standard diameters: 1300 mm, 1600 mm, 1800, 2000. This process always prefers large diameters than important lengths.

-          Capacity : 3 to 7 baskets

-          Maintenance :

• The fan and its motor is the heart of the process and needs a very regular checking
• If cooling with spray nozzles, these nozzles must be checked and cleaned regularly. Cooling is poor on such autoclave.

Applications

-          Food industry ( mainly sterilization)

-          Pharmacy : dry sterilization process for solutions pouches

Accessories

Special baskets for air steam

Options

bi-process (water and Air/Steam),  double door, internal conveyor, …. and all pharmaceutical options

History

First STERISTEAM or MONOFAN retort was built and patented by Steriflow in 1986.
