To cook or sterilize cereal germ-with or without admixtures such as salt-the material is passed slowly by a screw conveyer through a cylindrical vessel having a jacket supplied with heating fluid such as steam at a temperature of about 230-265 DEG F., and is then subjected, in the same vessel, to the direct application of steam which is introduced through pipes near the outlet end of the vessel; the treated germ is thereafter dried and cooled. The discharge chamber of the vessel may be provided with a conduit leading to an exhaust fan so as to create a gentle current of air or steam towards the outlet end of the vessel. The rate of travel of the material is such that the germ has a dry heat treatment for about 10 to 15 minutes, and is then subjected to direct steam treatment for about 5 minutes. Specification 12736/86, [Class 58], is referred to. |
