STERI TOP®
Process description
STERI TOP® is a Batch Steam Sterilization System developed by
TECHNI GRAU SOLUTIONS LTD designed for low moisture products without limit on size, mainly for: spices,
herbs, seeds and minerals for food, cosmetic and principally for pharmaceutical industries.
STERI TOP® process contains following steps:
• Product preparation for process and its loading in sterilization chamber, which happens in the
normal area intended for raw material storage. At this phase of the process, we have, firstly,
to decide which option of trolleys to use, trays, containers or lugs? This mainly will depend on the kind of conditioning
like bags or jumbo bags and in some case of kind of product and its sizes. This part is an innovative one
for the batch treatment. Then, secondly, have to position 12 calibrated sensors in various places of
loading as indicated in the validated recipe, in order to read and to ensure the homogeneous treatment
in entire reactor during the next step.
• Sterilization with wet steam under pressure in the chamber happens in the following main sequences:
heating, holding and cooling from 40 to 25°C. Each main sequence drives subsequently and depends on the
program setup. Due to the high precision of temperature, pressure and air ventilation monitoring, thanks
to TGS improved and innovative design, the residence time and homogenous treatment by using lowest amount
of steam in batch treatment is warranted and which allows the better product moisture and water activity control.
• Automatic unloading of the product from the chamber happens automatically once the previous step is
over based on the settled recipe validated and necessary for bacteria killing.
• Cooling down to 25 degrees in the Dry Cooling Unit (DCU) is an optional step and strongly advised
for products loosing energy very slowly and need direct chilling contact, thus increasing their rate of surface
heat exchange. The precise residential time will vary from 5 to 15 min. The used trolleys with trays or lugs
will move automatically through the buffer corridor. Then the cycle starts again.
• Conditioning which depends on the customer need once again without any risk of cross-contamination.
