A method for controlling a refrigerator according to an embodiment of the present invention is characterized by comprising: a step for determining whether a deep-freezing chamber mode is ON; and a step for determining whether a deep-freezing chamber load response operation input condition is satisfied, wherein when a cold chamber is determined to be operating at the time the deep-freezing chamber load response operation input condition is satisfied, the cold chamber operation is terminated and a deep-freezing chamber load response operation is performed.

A refrigerator according to the present invention comprises: a storage chamber in which food is stored; a cold air supply means for supplying cold air to the storage chamber; a tray forming an ice-making cell as a space in which water undergoes a phase change to ice by means of the cold air; a heater for supplying heat to the tray; and a controller for controlling the heater. The controller starts ice-making after water supplied to the ice-making cell by a first amount of water supply is completed. The controller turns on the heater in at least a part of a range in which the cold air supply means supplies cold air such that air bubbles dissolved in water inside the ice-making cell can move from ice-generating parts to liquid-state water, thereby generating transparent ice. The controller determines whether or not the heater is functioning abnormally in the ice-making process. If it is determined that the heater is functioning abnormally, the controller supplies water to the ice-making cell by a second amount of water supply, which is smaller than the first amount of water supply, during the next water supply process.

A contact drum freezer system includes a contact drum freezer, an endless product wrap belt and a cross feed conveyor. The contact drum freezer is mounted to revolve about an axis generally parallel to a main lane of transit. The endless product wrap belt has an intake shelf, an inner product-compressing run encircling most of the drum and an outer return run looping back to the intake shelf. The cross feed conveyor is situated in the main lane of transit and has a return run a and product-carrying run for transferring product laterally out of the main lane of transit and onto the intake shelf of the product wrap belt.

A method for grasping a row of multiple separate blocks of frozen food originating from a plate freezer, the row extending in a longitudinal direction corresponding to the longitudinal direction of the plate freezer, includes the steps of grasping the row of blocks along its opposing lateral edges by closing a clamp (1) having two grasping elements (2, 20) that extend along the opposing lateral edges of the row, wherein at least one of the grasping elements along its length includes multiple separate pinching elements (4, 40), each element for pinching one or more of the blocks, the pinching elements being individually movable with respect to the at least one grasping element in a direction perpendicular to the longitudinal direction of this grasping element, the method further including adjusting the lateral position of each pinching element when closing the clamp, by individually moving each pinching element.

A method efficiently changes the state of an object at low cost and in a short time, in which a state change control device changes the state of an object by bringing the object into contact with an ice slurry to cause a temperature change to the object. The device includes an ice slurry contact part that brings the object and the ice slurry into contact with each other at a predetermined relative speed and changes the temperature of the object, and an ice slurry supply part that supplies the ice slurry to the ice slurry contact part.

An equipment body of an ultrasonic rapid freezing equipment is provided with a placement cavity, and the placement cavity is provided with a first electric telescopic rod. The bottom end of the first electric telescopic rod is provided with a receiving plate connected to a movable plate, and the movable plate is driven by a motor to rotate. The equipment body is provided with a first conveyor belt, and the inner end of the first conveyor belt is equipped with a second conveyor belt. The second conveyor belt is located on a mounting frame, and the bottom of the mounting frame is connected to a second electric telescopic rod. The bottom end of the second electric telescopic rod is connected to a moving block, the roller at the bottom of the moving block is located in the track on the top surface of the supporting block.

A blast cell system is provided with simple and scalable designs that prevent short cycling of air flow through any pallets in blast cells. The blast cell includes a plurality of suction channels that provide independent fluid pathways for directing the air drawn from different rows in the blast cell into the fan.

Pallet racking systems are designed to quickly freeze items using thermal transfer by moving air through palletized products. Air is pulled through the palletized product to a negative air plenum behind the pallet rack. Back panels of the pallet racks provide variable-height airflow by use of louvers which are individually pressed open by the palletized product to accommodate differing product heights. The panels allow more efficient system operation with any number of rack positions filled.

A freezer case includes a refrigeration system and a controller. The controller is configured to store a plurality of setpoint instruction sets associated with a plurality of possible operating modes, select a current operating mode from the plurality of possible operating modes, assign a value for the superheat setpoint by executing the setpoint instruction set associated with the current operating mode, control the refrigeration system in accordance with the superheat setpoint.
