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 dry vapor cryogenic storage container includes an absorbent core made from a porous material that absorbs a liquid cryogen and releases the cryogen in vapor form as the absorbed liquid evaporates. Fluid channels are formed in the absorbent core to increase the available surface area through which the liquid cryogen can be absorbed. The core can absorb the cryogenic liquid much faster with inclusion of the fluid channels. The absorbent core can be made by cutting a cavity and drilling holes in a stack of calcium silicate panels. The cavity holds a contents container or an inner core. The inner core can be part of an extractor and made from porous material including fluid channels for absorbing liquid cryogen. Contents containers can be housed in the inner core.

In some embodiments, systems and methods are provided that limit the change in temperature and/or control a temperature of a product during delivery. Some embodiments provide systems to limit temperature changes, comprising: a product cooling system comprising: a product cavity that supports a product, wherein the product cooling system is separate from and removable from the delivery vehicle and comprises an insulation about the product cavity; a cryogenic substance dispensing system that injects a cryogenic substance into the product cavity; and a temperature sensor; and a temperature control circuit coupled with the temperature sensor and the cryogenic substance dispensing system, wherein the temperature control circuit is configured to determine that a temperature of the product is greater than a threshold, and autonomously activate the cryogenic substance dispensing system to release the cryogenic substance.

A cryogenic freezer features a dewar defining a storage space. A reservoir is positioned within or adjacent to the storage space and is configured to contain a cryogenic liquid with a headspace above the cryogenic liquid in a reservoir interior space that is sealed with respect to the storage space. A refrigeration module is in heat exchange relationship with the reservoir. A sensor is configured to determine a temperature or pressure within the reservoir. A system controller is connected to the sensor and the refrigeration module and configured so that the refrigeration module is adjusted to provide additional cooling to the reservoir when a pressure or temperature within the headspace increases.

A freezing apparatus invention is configured to be used for a refrigerating space. The freezing apparatus includes a liquefied gas supply module having a liquefied gas tank. A control module includes an electromagnetic valve intercommunicating with the liquefied gas tank and a control unit electrically connected to the electromagnetic valve.

A cooling module is mounted in the refrigerating space and includes a vaporization chamber intercommunicating with the electromagnetic valve. An exhaust module includes an exhaust valve intercommunicating with the vaporization chamber. The exhaust valve is electrically connected to the control unit.

A storage plant for storing objects at the temperature of liquid nitrogen comprises a plurality of storage tanks arranged in a cooled chamber. A nitrogen withdrawal apparatus is provided to carry off evaporated nitrogen directly from the storage tanks before it can enter the chamber. The pressure in the storage tanks is kept below the pressure in the chamber.

The invention relates to a cryogenic container for storing and/or transporting a medium, in particular a biochemical and/or medical product. The cryogenic container comprises at least one primary container, which has at least one flexible film bag. The flexible film bag is designed to receive the medium. The cryogenic container furthermore comprises at least one secondary container, which at least partially surrounds the primary container and is preferably at least partially flexible. The secondary container has at least one opening for insertion of the primary container. The secondary container furthermore has at least one preferably at least partially flexible outer sleeve. The secondary container furthermore has at least one heat exchanger space, which is arranged between the outer sleeve and the flexible film bag and receives at least one fluid heat exchange medium.

A freezer includes a plurality of evaporators coupled to a payload bay with a multiplicity of coolant tubes in each evaporator, wherein each tube enters and then exits the payload bay, further comprising one or more cryogenic valves coupled to the coolant tubes; a pump to force coolant flowing through the evaporators; sensors coupled to the evaporators of the freezer to monitor vital parameters of the freezer; a processor; a wireless telemetry system to communicate one or more measured characteristics of the freezer in accordance with a service level agreement to a remote computer; and at least one notification component that provides a notification associated with a specific customer responsive to the measured characteristic of the service crossing a pre-defined threshold.

A portable self-refrigerating autonomous system comprises a leak-tight tank in which a pressurized liquefied gas is stored, at least one evaporation control valve and a filling valve, all the valves being connected to the leak-tight tank. The at least one evaporation control valve also cooperates with a temperature and/or pressure sensor, and an actuator is intended for controlling the opening of the at least one evaporation control valve.
