Abstract

1426917 Preservation GRUMMAN ALLIED INDUSTRIES INC 11 April 1973 [20 April 1972] 17426/73 Heading A2D A method of preserving non-mineral matter in cool, humid air in an enclosed space comprises taking air from and adding air to said space, maintaining the air pressure in the space at 4-200mm Hg (absolute), maintaining the air temperature at -2 to +15‹C and maintaining the relative humidity at 80 to 100%, the temperature of the water employed to maintain said humidity being maintained sufficiently higher than the temperature in the space to provide a relative humidity in said air of between 80 and 100% and selecting correlated pressures, temperatures and humidity with respect to the matter being preserved. The method is applicable to the treatment of fruit, vegetables, poultry and flowers. The method may be carried out in the apparatus shown in Fig. 1. In this apparatus, material L is stored in an insulated vacuum chamber 10, and a current of air (arrowed) of desired temperature and relative humidity is circulated about the interior of the chamber. Air is continuously evacuated from the chamber by pump P and fresh air enters the chamber by the pipe 16. This fresh air passes through a heat exchanger 20 so as to be cooled to the temperature of the air in chamber 10. A portion of the cooled fresh air passes to air mover 24 which is of the venturi-type and thus air will be sucked from the chamber into the inlet elbow 28. Air is thus drawn into the humidifier 11 and after passing up through the humidifier, this air is passed back into the chamber at outlet 25. A portion of the inlet fresh air, instead of passing to chamber 10, passes through pipe 38 to spray nozzle 35. A spray of water, heated if necessary by heater 61, is thus delivered into the upper regions of humidifier 11.
