Drying and Cooling-Systems for Soap

In addition to the highest possible demands for quality, the call for energysaving and environmentally compatible production are becoming more and more important.

Society's and industry's demands, as well as its own commitment to protecting natural resources, led Sela earlier on to develop environmentally compatible processes. Such processes can only be designed in collaboration with our clients. Detailed knowledge of local conditions mean that we can offer environmentally compatible solutions. And in the soap drying process in particular, the development of new processes achieved considerable energy and cost savings.

In addition to the demands for energy and cost savings, the reduction of waste and by-products is becoming increasingly important. A vacuum drying process for a major german soap manufacturer needed further development to significantly reduce the amount of soap dust generated while drying neat soap. Another demand was to use only one instead of the two dust seperators then in operation to seprate out virtually all of the already strongly reduced amount of drying dust. A method was designed in collaboration with the client and resulted in a new spray-chamber design with special spray-nozzles combined with a special dust seperator. This set a new standard for the soap drying process which not only reduced the amount of dust generated during drying to a previously undreamt of small quantity, but also separated out virtually all of this dust.

In the vacuum drying process developed by Sela, the concentration of soap in the vapour is the lowest of any comparable machine produced anywhere - stringent maximum values are guaranteed by Sela. This is an innovation which benefits all soap manufacturers and the environment.
