Many bulk solids processing applications require mixing of solids and liquids under both pressure and temperature to achieve a desired finished product. Pressure or vacuum can be applied to the internal portion of the vessel where the bulk solids are being processed. The bulk solids can be heated or cooled as required by external jackets that are integral to the vessel walls. KWS coded pressure vessels combine our knowledge of conveying and mixing with the science of heat transfer.
Achieving the specified exit temperature of the product is accomplished by calculating the required surface area of the vessel jacket and designing the system flow to match the heat load requirements of the application. Heat is transferred indirectly to or from the product by introducing a heat transfer medium such as cool water, hot oil or steam through the special vessel jacket.
