Abstract: A vessel having an opening for receiving the product and walls surrounding the vessel at all sides except the opening. The interior of the vessel is filled with a fluid having a specific gravity lower than a specific gravity of a medium surrounding the walls outside the vessel. While the vessel is oriented with the opening facing downwards, the vessel and/or product is/are conveyed to ensure that the product enters the interior through the opening.

Abstract: A method of controlling the conditions of air in an interior of an enclosure is disclosed. The method comprises collecting air from a lower part of the interior, dehumidifying the collected air, and releasing the dehumidified air in an upper part of the interior, thereby controlling the conditions of the air in the interior of the enclosure.

Abstract: A multi-purpose structure, especially useful as a greenhouse or other plant-protective structure, comprising; (a) a framework comprising a plurality of vertical supports, said vertical supports being arranged in rows that extend the entire width of the structure, wherein each of said rows contains at least two vertical supports having substantially the same height, said framework further comprising a plurality of connecting members that connect the vertical supports in a row to one another at junction points located at the tops of said supports; the framework further comprises a plurality of permanent cross strips extending perpendicularly to said connecting members; (b) at least one flexible sheet adapted to be weaved through said connecting members and extending the entire length of the framework so as to form at least a part of a roof of said framework.
