Diasteril
A state of the art, gentle bacteria reducing procedure without the use of steam, vacuum or pressure.
The product is carried away from a permeable trough with gas flow circulation and with a total speed residence time control by direct contact with a hollow shaft screw where the cold fluid circulates in the screw. At the same time, the product is cooled by radial contact with a dry and cold gas current that passes through the double paddle shaft of the trough.
This double simultaneous function allows a very significant improvement of the global exchange coefficient, thus of the energy performances of the equipment. This is thanks to the fluidisation of the product by the air stream and the non condensation of the ambient air around the product during the cooling process. This prevents the renewed reproduction of bacteria by arriving at a specific critical temperature and remaining humidity.
Diasteril has been conceived in such a manner that leaf, coarse cut products, granules and powders can be reliably bacteria reduced without the sensory qualities of the products being impaired.
The Diasteril bacteria reducing procedure is available to our customers as a contract service and the faciliy itself can be purchased and installed at your own production site.
