A CA system includes a gas supply device which performs a gas supply operation of supplying nitrogen-enriched air into a container, and a controller which performs the gas supply operation so that the inside air has a desired composition. The controller performs carbon dioxide priority control in which the controller performs the gas supply operation if an oxygen concentration of the inside air is equal to or higher than a ceiling concentration higher than a target oxygen concentration, stops the gas supply operation if a carbon dioxide concentration of the inside air is lowered to a critical concentration lower than a target carbon dioxide concentration, and restarts the gas supply operation if the carbon dioxide concentration of the inside air has reached a restart concentration higher than the target carbon dioxide concentration through breathing of the plants.

A plant drying and curing device comprises a plurality of plant curing zones. A control system is configured to control one or more environmental conditions in each of the plurality of plant curing zones, and a receiver is configured to receive input data and process data according to a prescribed algorithm to control the one or more environmental variables.

A device for the vacuum storage and vacuum transport of dry or wet grain under anaerobic conditions is provided, comprising: an enclosure sealed to all types of gas having at least one filling element, the filling element, when in the open position, allowing the enclosure to be filled with grains and, when in the closed position, further allowing the enclosure to be tightly sealed, and at least one non-return air valve allowing gaseous fluid transfer by the suction of air through the valve only from the inside of the enclosure to the outside of the enclosure. The device further comprises a handling arrangement associated with the enclosure and comprising a transport bag suitable for receiving the sealed enclosure and having straps that form loops that can be gripped directly by a user or by lifting equipment.

The invention relates to a vegetable box which is capable of preserving the products in the box in a fresh state and for an extended period of time by exchanging the air composition inside the box via the respiration and photosynthesis of the fresh fruits/vegetables, and thus ensuring the oxygen and/or carbon dioxide to reach the target partial pressure and stabilizing the same at these values. The invention is characterized by comprising a lock sensor (6) which is arranged in the internal portion of the body (1) at the section where the body (1) contacts with the cover (2) and which senses the opening/closing of the cover (2); a gas sensor (7) which is disposed inside the body (1) and which measures the partial pressure of the oxygen and/or carbon dioxide gases inside said body (1), and then informs the control unit (9) of the obtained pressure values; and an electronic control unit (9) which, using the information from the lock sensor (1) and gas sensor (7), activates/deactivates the lighting unit (8) and which is disposed in the body (1).

The present invention is directed generally to a demountable silo (10) comprising a series of interconnected silo modules (12A to 12F) constructed in accordance with a preferred embodiment of this invention. The silo modules such as (12A) are each of a substantially identical configuration and interconnected in a side-by-side and end-to-end relationship. The demountable silo (10) is designed to contain particulate material and configured depending on the nature of the material and its storage requirements. It will be appreciated that the provision of multiple silo modules such as (12A to 12F) together contains significantly more particulate material in a heap than a single silo module. The maximum storage capacity for the demountable silo (10) is determined largely by the angle of repose of the heaped particulate material.
