Abstract: The method and apparatus of the invention for the continuous roasting of food materials are such that the food material being fed into a heated tubular cylinder is mixed up within and transferred through said tubular cylinder while the vaporized components of the food material are recovered and cooled to liquefy. The apparatus may comprise the horizontally placed tabular cylinder with an open front end, the coil screw inserted into the tubular cylinder in such a way that it can be driven to rotate, and the cooling unit that is connected to a vent port formed in the middle part of the tubular cylinder.

Abstract: A method and apparatus for supplying and maintaining an aseptic gas atmosphere in a storage tank for spoilable contents such as foodstuffs and the like. The aseptic gas is supplied from a container under pressure and is maintained at the desired pressure in the storage tank by pressure-reducing valves in a supply line or conduit having a microbiological filter and pressure-maintaining valve that functions in place of a relief valve in the supply line. It responds to excess pressure in the storage tank and relieves the excess pressure through the same supply line through which gas is supplied without need of a relief valve on the storage tank.

Abstract: An aseptic valve for regulating supply and discharge of a semi-processed food product in an aseptic storage tank. The valve is provided with a valve body on which is mounted a bonnet housing a bushing. These three elements define three chambers in which a sterilizing liquid is retained. The three chambers bathe parts of the three principal parts of the valve with the sterilizing fluid and maintain paths of entry of microorganisms blocked by the sterilizing liquid so that the valve and the system to which it is connected are maintained sterile.
