Abstract
1379707 Preserving perishable material SNAM PROGETTI SpA 1 March 1973 [1 March 1972] 10099/73 Heading A2D A method for preserving perishable material comprises passing through said material a stream of nitrogen having a relative humidity in the range from 45 to 70%; monitoring the humidity of the stream of nitrogen after its passage through the perishable material; and controlling, in response to the monitored humidity, the relative humidity of the stream of nitrogen before its passage through the perishable material. The nitrogen stream may comprise pure nitrogen or may contain small amounts of oxygen e.g. less than 2% of oxygen. Other gases inert to the perishable material may be present in the nitrogen stream in small amounts. The method may be carried out in the apparatus shown in Fig. 1 wherein nitrogen is passed from supply pipe 1 via pipe 6 to the upper region of container 7. A monitoring device 9 in the nitrogen exit pipe determines the relative humidity of exit nitrogen and, depending upon the value of the relative humidity, two-way valve 2 may be activated to divert incoming nitrogen into humidifier 3. The relative humidity of the incoming nitrogen is thus controlled. The method is particularly applicable to the preservation of cereals and seeds.
