Benefits of technology

The invention is a device that regulates the gas composition in a container where bananas are stored and shipped. The device is simple and uses little energy. It uses a membrane to exchange oxygen and carbon dioxide, maintaining the desired ratio of these gases and compensating for changes caused by the bananas' respiration. This helps to prevent the bananas from maturing too quickly and maintains their freshness.

Problems solved by technology

However, bananas respire during storage (take in oxygen and release CO2), which modifies the required conditions for storing them.

Embodiment Construction

[0030]Container (1) (FIG. 1) contains the load, for example, in the form of packaged fruits (2). Transfer and stirring of gas medium inside the container is ensured by the charger (3). The device for control of the gas medium inside the container (1) is embodied in the form of a chamber (4) with an inner space (5) (see FIG. 2) and a gas-permeable membrane (6). The membrane separates the inner space (5) of chamber (4) from the external ambient air. A connecting pipe (7) of the container (1) and the hose (8) form a channel for uptake of the gas medium from the container (1) and for feeding it into the chamber (4). The connecting pipe (9) and the hose (10) form a channel for return of the modified gas medium from the chamber (4) to the container (1).

[0031]Valves (11 and 12) are installed on connecting pipes (7 and 9). These valves are connected to the corresponding control system (not shown in FIG. 1), containing sensors and devices controlling the operation of the valves (11, 12) and ...

Abstract

A device for controlling the composition inside a shipping / storage container for produce, such as bananas, is disclosed. Such atmospheric control is particularly important when dealing with the ripening of respiring fruit. The device comprises a chamber surrounded by an outer wall, at least a portion of that wall made up of a selectively gas-permeable membrane which is in communication with the outside atmosphere. The chamber also includes at least two channels which are connected to the container: one which transmits gas form the chamber to the container, and one which transmits gas from the container to the chamber.

Description

[0001]This application is based upon and claims priority from U.S. Provisional Patent Application No. 60 / 697,722, Fernandez et al., filed Jul. 8, 2005, incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention is related to container shipping and storage of produce, in particular, to the means for controlling the gas composition in such containers.BACKGROUND OF THE INVENTION[0003]Transfer of fruits in shipping containers necessitates a certain composition of a gas medium inside the container. That composition should change depending upon the type of fruits, the degree of their ripeness, and the technology for preparation of these fruits for sale.[0004]There are known inventions related to the systems for controlling gas media in shipping containers.[0005]U.S. Pat. No. 5,333,394, “Controlled atmosphere container system for perishable products”, Herdeman, et al., issued Aug. 2, 1994, includes a description of a system that is connected to the inlet connecting pipe of ...
