ABSTRACT:
A ripening room is disclosed for ripening perishable products, such as fruits and vegetables, and more particularly bananas, in which the air flow and temperature are closely controlled by the room construction and by a cooling control system that archives uniform ripening of the fruit regardless of the physical location of the fruit within the room. These desired results are accomplished using a minimum quantity of energy and cooling capacity by use of an improved cooling controller that gradually changes the temperature setpoint over time to allow the cooling (refrigeration) system to operate near its full capacity without any periods of intense cooling (due to sudden changes of the temperature setpoint, as in the prior art). The uniform ripening is also achieved by an improved air distribution system that provides a greater back pressure in portions of a ripening room that, in conventional designs, receives far too much air flow.
