Storage and Handling
For applications in which colour or colour stability are important stainless steel should be used. In vessels fabricated from this material stearine can be stored at temperatures up to a maximum of 65oC without appreciable loss of quality. However, the storage temperature should be held at a practical minimum and ideally an inert gas blanket should be maintained in the storage tank. Hot water should be used in the heating coils but if this is not available low temperature saturated steam can be used.
Liquid stearine can be handled by conventional centrifugal pumps.
Further information on storage and handling can be obtained through the Symex Holdings Limited Sales Office or agent.
