  • Patent number: 6224315
    Abstract: The invention relates to a method for emptying a container filled with products such as agricultural or horticultural products by immersing the container in a basin filled with liquid, causing the products to flow out of the container and lifting the emptied container out of the basin, wherein the container is tilted in the basin and lifted out of the basin in a curved path. In this manner products which do not float, or hardly so, can be offloaded quickly and efficiently without danger of damage. The invention also relates to an apparatus for performing this method. Such an apparatus is provided according to the invention with a basin filled with liquid and means for immersing the filled container in the basin and lifting the container therefrom after offloading of the products, which immersing and lifting means are adapted to perform a combined tilting and translation movement along a curved path during offloading of the products.
