ABSTRACT:
The invention relates to a device and method for ripening fruit, such as bananas, comprising a chamber containing a frame in which at least two rows of loaded pallets are placed one above the other, in such a way that there is a free space on either side of the rows of loaded pallets, and comprising cooling means for the cooling of fluid provided in the lengthwise direction along the frame, and circulation means for conveying the fluid from one longitudinal side of the frame to the other longitudinal side, in such a way that a pressure difference arises between the space at one longitudinal side and the other, as a result of which the fluid flows back essentially in the horizontal direction through the load on the pallets from one longitudinal side to the other. According to the invention, the frame is in this case such that it provides for an essentially horizontal space between the loads of two rows of loaded pallets placed one above the other, by way of which horizontal space the circulation means convey the fluid from one longitudinal side to the other longitudinal side, said horizontal space being bounded at the bottom and top side by bottom and top seals respectively, and the cooling and circulation means being disposed essentially at the level of the horizontal space.
