Witton Chemicals has many years of experience in drying many different types of powder. We currently have 3 dryers for main production and a vacuum oven for scale up work or low volume materials.
The large stainless steel Vrieco-Nauta dryer can dry batches up to 800kg of dry powder per batch. It has an operating temperature of 10-95°C and vacuum down to <40mb absolute. It is connected to a vacuum pump with the latest membrane technology to reduce emissions. This also allows the capture of solvents for possible reuse in the process so helping to reduce costs.
Witton also has a smaller Vrieco-Nauta dryer and stainless steel ribbon dryer which offer capacities up to 500kg of dry powder per batch. They also have an operating range of 10-95°C and vacuum down to less than 40mb.
Material can be packed as required from the dryers into FIBCs, kegs or bags. All dryers are fitted with dust extraction systems. Witton has experience in drying a few kilos up to campaigns up to several hundred tonnes per annum.
