Vacuum cooling or ‘evaporative’ is achieved through the evaporation of a part of product moisture under vacuum conditions. By the utilisation of vacuum, we are able to reduce the boiling point of a product – driving off the latent heat by boiling off vapour. This, in turn, causes the product to fall in temperature.
By continually reducing the pressure, we can continue to reduce the temperature of the product. This is achieved rapidly and therefore very fast cooling rates can be assured.
Although cooling rates can vary between different products types, our systems maintain a high level of consistency, quality and repeatability.
We are able to provide machines that can handle viscous and dry products by combining the cool and cool process in the same vessel.
Discharge is effected by way of the kettle tiling into storage solutions for downstream processing.
