  • Patent number: 5475926
    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.

  • Patent number: 5438917
    Abstract: The invention relates to a method for ripening fruit, such as bananas, and a device fop carrying out the method. According to the invention, a fluid is cooled and guided along the fruit by circulation means conveying said fluid through a load of fruit placed on a pallet, the load being sealed essentially in an airtight manner in the peripheral direction, and the load being placed above or below the circulation means, while the fluid is conveyed through the load essentially in the vertical direction by the circulation means. The circulation means preferably suck the fluid up through the load from the bottom or down through the load from the top, and then guide it along the cooling means, following which, as the result of a pressure difference caused by the circulation means, the fluid is conveyed again along the outside of the load to the bottom or top side, respectively, thereof.
