This cryogenic preservation or vitrification device (1) comprises: an accumulator (2) including a first volume of pressurised hydraulic oil; a control system controlling a valve (20) capable of releasing a second volume of hydraulic oil from the accumulator toward a cylinder (55) by means of a pipe (4); a cylinder (55) including a piston (6) configured to be driven by the second volume of hydraulic oil and to displace a first volume of cryogenic fluid to a cryogenic vessel (7) intended to receive a sample (8) to be cryogenically preserved.

An instant freezer apparatus able to freeze consumable fluids and food having a freezing point lower than water is disclosed. The method of the present invention is directed to freezing of a substance such as to instantly freeze consumable fluids and food without altering their chemical compositions. The instant freezer apparatus generally comprises a main frame and a removable freezing module. The apparatus may further comprise a freezing fluid injection system such as a liquid carbon dioxide tank or a liquid nitrogen tank fluidly connected to the main frame. At least two freezing cells comprising the fluid to be frozen may be included, the freezing cells being independently removable from the freezing module and other freezing cells. A semi-flexible mat for receiving and supporting varying shapes of freezing cells may be included.

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 an apparatus for sensing the temperature of a refrigerator having a deep freezer compartment. A voltage value outputted from a temperature sensing unit is amplified according to a predetermined amplification ratio. Thereby, when a temperature is measured within the same temperature range, the range of voltage values output from the temperature sensing unit may be significantly widened. The temperature sensing apparatus is particularly adapted for temperature sensing of a deep freezer compartment, which has a temperature lower than a typical refrigeration compartment or freezer compartment.

A refrigerator and method of supplying coolant material are provided, the refrigerator including an interior and a main cooling loop, at least a portion of the interior includes a freezer section and at least a portion of the main cooling loop includes an evaporator. The refrigerator includes at least one detachable module having at least one connector, the detachable module configured to removably attach to a surface of the refrigerator, and a secondary cooling loop having at least one connector that corresponds to the at least one detachable module's at least one connector, wherein at least a portion of the secondary cooling loop is in thermal communication with at least one of the main cooling loop, the evaporator, and the freezer section, and wherein the secondary cooling loop is configured to be in fluid communication with the at least one detachable module through the corresponding at least one connectors.

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.

A refrigerated storage unit 1 includes: a refrigeration chamber S2, a refrigeration part 3 for cooling air inside the refrigeration chamber S2, a fan 4 for sending cold air cooled by the refrigeration part 3 into the refrigeration chamber S2, a temperature sensor 5 for detecting a temperature inside the refrigeration chamber S2, an infrared sensor 8 for detecting a temperature of a content provided inside the refrigeration chamber S2, and a control part 7 for controlling driving of the fan based on a result detected by at least one of the temperature sensor 5 and the infrared sensor 8.

To provide a functional continuous rapid freezing apparatus with which cold air is made uniformly contact with the whole face of an article to be frozen, easily and rapidly passing the maximum ice crystal generating zone, and the central portion of the article to be frozen can reach for the predetermined temperature within a short period of time, a freezing chamber 2 in which an article Q to be frozen is stored, a heat exchanger 1 for cooling disposed on a central portion of the freezing chamber 2 as a partition to divide the freezing chamber 2 into a first freezing block 2a and a second freezing block 2b, a first blowing fan 5 disposed to face the heat exchanger 1 for cooling through the first freezing block 2a, and a second blowing fan 6 disposed to face the heat exchanger 1 for cooling through the second freezing block 2b, are provided.

A portable apparatus for rapidly freezing a freezable liquid to form at least one frozen object includes a fluid intake in which the freezable liquid is introduced and a freeze chamber that receives the freezable liquid from the fluid intake. The freeze chamber includes a freeze block that includes at least one cell in which the at least one frozen object is formed. A cooling system circulates refrigerant to the freeze block to facilitate cooling of the freeze block. The freeze block is formed of a heat transfer material such that heat from the freezable liquid added to the at least one cell is transferred to the freeze block whereupon said heat is transferred to the refrigerant flowing through the evaporator coil of the freeze block, thereby resulting in cooling of the freeze block. The freeze block is configured and the refrigerant is selected such that the freeze chamber is maintained at a temperature of below 0° F. and preferably below at least about −10.0° F. or −20° F.
