Abstract

559,074. Preserving grass &c. EVERY, C. E. (Graham, W. R.). Dec. 22, 1941, No. 16518. [Class 49] Food substances, forage crops and vegetables rich in vitamins, carotene and other labile substances are stored in vessels containing mert gas such as carbon dioxide or nitrogen. The comminuted material is fed through pipes 11 by helices and discharged into hoppers 15 which may be closed at the top by gastight covers 23 and by valves 21 at the outlet. Valved branches 16 lead into the closed bins 10. Discharge from these is by way of intermediate hoppers 30 valved above and below, on to conveyers 38. Vacuum pumps withdraw air from the hoppers 15 before the outlets are opened, and the bins 10 are filled with inert gas before the entry of the material. The gas is stored in a tank 39, and passes therefrom through an automatically regulated valve 45 through individual valves 43 to the bins, leaving these by valves 48 and returning to the tank by way of a scrubber 51, chamber 50, drier 54 and pump 44. Constant pressure in the storage chamber is thus maintained.
