CONTAINER APPARATUS

摘要

PURPOSE:To provide a container apparatus for the transportation and storage of vegetables and fruits and capable of easily controlling the atmospheric gas in the storing space. CONSTITUTION:This container apparatus is composed of a storage vessel 1 having a gas inlet port 2 and a gas outlet port 3 having two-way cocks 4, 5 for connecting or disconnecting the container to the outer atmosphere and a spiral module 6 composed of a gas-separation composite membrane and attached to the gas inlet port 2 of the storage vessel 1. The nitrogen in air is concentrated by the spiral module 6 and the obtained nitrogen-enriched air is supplied to the storage vessel 1 to replace the gas in the storage vessel 1 with the nitrogen-enriched air to get a prescribed oxygen concentration.
