The Researching Of Rice Mildewproof And Fresh-keeping In Army

It is very easy for deterioration of the stored rice results from interactions among fungal, mites, and rodents. Constantly, this problem puzzle ours army, especially in basic level troops. For a long time, rice delivered by the higher authorities was simpler stack in warehouse. These rice was common knit pack, use this method to store, rice was to deteriorate very easy. Rice supply was very hard In island forces and naval vessels, they must store rice can edible half year or more. As the air temperature and humidity in the south are high, the rice mildew easy in store.OBJECTIVE: Find a new methods to solve the problem of grain mildewing and keeping fresh. This methods can prevent grain mildewing and keep fresh significant. It cost very low for use this methods to store rice. This guaranteed our army broad ranks of officers and men's health, avoids the non-combat losses, the guarantee army's fight.METHODS: 1, Comparing the efficiency of packing material can found in market. The factors are: tensile strength, density, thickness, oxygen transmissivity, and price. Calculating the cost for vacuumize 1kg rice use different packing material.2, Vacuumizing rice by packaging machine use PA/PE. The presentation was each bag packed 2kg rice. There was 40 vacuumize rice and 6 common knit packing rice set at warehouse, it's temperature was common and humidity was high. The time for rice stored was six months. Checking the stored vacuumize rice every day for find air leak in time, simultaneous recording the temperature and humidity in the warehouse.3, fungi amount and flora in two kinds package rice every month, using general isolation and identification methods of rice fungi. Comparing the different of fungi quantity and fungi flora of tow kinds package rice. Detecting the physico-chemical property of tow kinds package rice, Comparing the freshness of tow kinds package rice.RESULTS: 1, the PA/PE is best packing material for it's tensile strength, density, thickness, oxygen transmissivity, and price are very good. The cost for use PA/PE to Vacuumiz rice was lowest, only 0.004 Y for Vacuumiz lkg rice.2, the PA/PE have satisfactory gas-tightness, there was not found air leak in six...
