Abstract
Systems and methods for washing and thawing objects, such as vegetables and fruits, where large amounts of lifting of heavy items is minimized, complex and expensive pumping and manifold systems and structures are not required; and system cost and daily maintenance is reduced. The system includes a structure for holding a volume of fluid, a vertical motion structure driven by an electric motor or the like that raises and lowers a basket carrier between an elevated position and a lowered position. In the lowered position, one or more baskets are positioned on a basket carrier and are repeatedly lowered into and raised from the volume of fluid.
Claims20
A system for introducing at least one mass of objects to and removing the at least one mass of objects from a volume of fluid, the system comprising;
- a partially enclosed structure comprising a lower tank portion for holding the volume of fluid and an upper loading portion accessible through a partially open front panel, the partially enclosed structure having a closed top;
- a mechanical system positioned substantially over the closed top of the partially enclosed structure for creating a substantially vertical linear motion for introducing the at least one mass of objects to and removing the at least one mass of objects from the volume of fluid, the mechanical system comprising a drive mechanism statically fixed in position to the partially enclosed structure, a drive linkage operably connected to the drive mechanism, and at least one vertically movable lift rod operably connected to the drive linkage, the at least one vertically movable lift rod extending down through the closed top of the partially enclosed structure;
- a support structure positioned within the partially enclosed structure, the support structure connected to the at least one vertically movable lift rod of the mechanical system through at least one connection point;
- and
- at least one permeable structure for holding the at least one mass of objects, the at least one permeable structure removably attachable to or supportable by the support structure.
A method of controllably washing, thawing or processing at least one mass of objects in a volume of fluid, the method including the steps of:
- selecting a specific predetermined operation for washing, thawing or processing to be performed from a set of predetermined operations;
- introducing the volume of fluid into a partially enclosed structure for holding the volume of fluid and monitoring a level of the volume of fluid;
- monitoring a temperature of the volume of fluid;
- optionally heating or cooling the volume of fluid to achieve a predetermined temperature range based on the selected predetermined operation for washing, thawing or processing being performed;
- placing the at least one mass of objects at least partially onto or within at least one permeable structure;
- introducing the at least one permeable structure onto or into a support structure positioned within the partially enclosed structure, the support structure operably connected to a mechanical system for creating a substantially vertical linear motion for the at least one permeable structure within the partially enclosed structure for holding the volume of fluid;
- performing a repetitive sequence of vertical linear motions imparted to the at least one permeable structure, the sequence defined by the selected predetermined operation for washing, thawing or processing being performed, to move the at least one mass of objects in the at least one permeable structure into, within, and out from the volume of fluid;
- continuing to monitor the temperature of the volume of fluid and if required, heating or cooling the volume of fluid as needed to maintain the predetermined temperature range;
- and
- upon completion of the step of performing the sequence of vertical linear motions, removing the at least one permeable structure from the support structure positioned within the partially enclosed structure, and removing the at least one mass of objects from the at least one permeable structure.
