Abstract
Apparatus for storing produce under controlled conditions embodied in a transport container (5) for maintaining produce under controlled conditions during transportation. Nitrogen-rich gas and carbon dioxide gas are supplied to the container when required by a compact and efficient system wherein the nitrogen gas is generated from the ambient air surrounding the container using an air splitter (35) and the carbon-dioxide is generated from a store of dry-ice (40).
Claims13
Apparatus for storing produce comprising:
- a substantially sealable container having a hollow interior for containing the produce;
- nitrogen rich gas generating means having an inlet means communicating with ambient air surrounding said container and a delivery means communicating with said hollow interior so that said gas generating means generates nitrogen rich gas from the ambient air and delivers said nitrogen rich gas to said hollow interior;
- oxygen level adjusting means in said delivery means for varying the oxygen content of said nitrogen rich gas delivered to said hollow interior;
- first monitoring means operatively connected to said container and said nitrogen rich gas generating means for detecting the oxygen level within said container and controlling the operation of said nitrogen rich gas generating means when said oxygen level is other than a predetermined level;
- dry-ice storage means;
- carbon dioxide gas control means connected to said dry-ice storage means and said hollow interior for delivering carbon dioxide gas from said dry-ice storage means to said hollow interior;
- and
- second monitoring means connected to said container and said carbon dioxide gas control means for detecting carbon dioxide gas level in said container and operating said carbon dioxide gas control means when said carbon dioxide gas level is below a predetermined level.
