Environmentally controlled storage of fruits and vegetables

摘要

PROBLEM TO BE SOLVED: To solve the problems that the reduction of an equipment cost, the reduction of electric power consumption and the assurance of the simplicity of operation and the ease of maintenance are heretofore not possible. SOLUTION: This environment control storage method for fruit vegetables consists in maintaining the in-storage house gases of CO2 necessary for maintaining the freshness of the agricultural products of a storage house and removing volatile org. materials, such as ethylene, acetoaldehyde and terpene. An adsorption column 6 packed with high silica zeolite 5 is used in this method. In-storage house gases contg. the volatile org. materials are brought into contact with high silica zeolite 5 to adsorb the CO2 and the volatile org. materials under the conditions under which the concn. of the in-storage house gases contg. the volatile org. materials of the storage house is high and thereafter, the CO2 and volatile org. materials adsorbed to the high silica zeolite 5 are released outside the system.
