A multitemperature storage system includes a storage structure including a plurality of upright members , a plurality of horizontal members supported by the upright members and forming a grid pattern defining a plurality of grid cells and allowing containers to be arranged in stacks beneath the grid cells defined by the grid pattern, and a track structure on top of the horizontal members , the track structure being configured to allow a load-handling device to move across the storage structure to retrieve a container from a stack ; and including temperature-control to maintain a first-temperature region within the storage structure at a first temperature and a second-temperature region within the storage structure at a second temperature.

A device for the handling and the low-temperature storage of probe tubes in tube racks includes a low-temperature compartment having insulated side and bottom walls and at least one opening at a top side. The compartment is used for storing at least one tube rack at a low temperature. The device has a holder apparatus comprising a rack holder for holding a tube rack and a picker apparatus comprising a gripper adapted to remove and insert individual tubes from or into a tube rack held by the holder. The holder apparatus is adapted to displace the rack holder between an upper rack position outside low-temperature compartment above the opening and a lower rack position inside the compartment. The picker apparatus is adapted to displace the gripper between an upper gripper position outside the compartment above the opening and a lower gripper position inside the compartment below the opening.

A refrigerator includes a cabinet defining a storage chamber, a drawer door, a rail that slidably couples the drawer door to the cabinet, a driving device provided in the door part, an elevation device provided in the drawer part to vertically ascend or descend at least a portion of the drawer part, and an elevation detection device. The drawer door includes a drawer part configured to be inserted into and withdrawn out of the storage chamber and a door part coupled to the drawer part and configured to open and close the storage chamber. The driving device includes a motor assembly, a screw assembly having a screw and a screw holder, and a lever that couples the screw holder to the elevation device and is configured to be rotated based on the movement of the screw holder along the screw.

A system for blast-freezing items includes a plurality of cells arranged side-by-side, each cell including a housing with a bay space, a plenum, a front air passage, a rear air passage, and a fan. The fan is positioned in the plenum and configured to circulate air through the bay space. Each cell also includes a plurality of channels to separate pathways of air to segments of the bay space. The system also includes a plurality of crane rails extending between rows of cells and at least one crane capable of traveling along the plurality of crane rails to load or unload each of the plurality of cells.

The present disclosure relates to stacked, grid storage systems such as densely packed storage systems, and methods of adjusting, regulating, controlling and maintaining the temperature of storage systems.

An elevation device for a refrigerator drawer includes a lower frame, an upper frame, and a lifting assembly. The lifting assembly includes: a pair of first rods having a first end rotatably coupled to the lower frame and a second end that translates along the upper frame; and a pair of second rods having a first end rotatably coupled to the upper frame and a second end that translates along the lower frame. The second rod is rotatably coupled to and crosses the first rod. The first or second rod is connected to a driving device via the first end of the first or second rod, with the driving device disposed outside the upper frame and the lower frame. The first and second rods are configured to, based on power from the driving device, rotate about their respective first ends to elevate the upper frame relative to the lower frame.

A spiral chiller and a method of chilling a food product in a spiral chiller using a cooling medium wherein (a) the food product is conveyed within the chiller by a spiral conveyor having a plurality of spiral flutes and (b) the cooling medium is discharged either upwardly and/or downwardly within, and/or laterally into, one or more vertical gaps between adjacent pairs of spiral flutes using one or more delivery duct structures which extend inside the interior of the product chilling chamber.
