A storage system (1) has a chamber (3). In the chamber (3), multiple storage tanks (5) are arranged, and a picking and placing device (8) is arranged above these tanks. Carrousels (8) are arranged in the storage tanks. These carrousels are suspended from a top pivot bearing (35) and laterally guided by a bottom pivot bearing (44). The top pivot bearing (35) is located outside the insulation (12) of the storage tanks and is thus protected from extreme temperatures. In the carrousel (18), storage cassettes (20) are arranged which are laterally held by guide elements (31).

A method and system for controlled rate freezing of biological materials is provided. The presently disclosed system and method provides the ability to rapidly cool the biological materials contained in vials or other containers within a cooling unit via forced convective cooling using a laminar and uniform flow of cryogen in proximity to the plurality of vials disposed within the cooling unit. The rapid cooling of the biological materials is achieved by precisely controlling and adjusting the temperature of the cryogen being introduced to the system as a function of time.

A method and system for controlled rate freezing and nucleation of materials is provided. The presently disclosed system and method provides the ability to rapidly cool the materials contained in vials or other containers within a cooling unit via forced convective cooling using a laminar and uniform flow of cryogen in proximity to the plurality of vials disposed within the cooling unit. The rapid cooling of the biological materials is achieved by precisely controlling and adjusting the temperature of the cryogen being introduced to the system as a function of time. The presently disclosed methods to systems also provide nucleation control via temperature quench and depressurized nucleation control.

An apparatus and method of flash freezing a tea-based liquid into small beads and then packaging the beads for consumers is disclosed. The beads are stored in a conventional freezer until desired and then reconstituted into a tea beverage base as needed. In particular, a warm or cold tea-based beverage may be easily and affordably created using the frozen beads.

摘要:
To provide a preserving system capable of re-using vaporized nitrogen, and moreover, capable of always cooling the specimens at a predetermined temperature or lower. The preserving system comprising a cylinder and the preserving vessel which is supplied with liquid nitrogen from this cylinder, is provided with a Stirling refrigerator and a condensing chamber arranged outside of said preserving vessel, and the gas phase part of this condensing chamber is made to communicate with that of said preserving vessel and also the liquid phase part is made to communicate with that of said preserving vessel, and further the cooling part of said Stirling refrigerator is arranged in said condensing chamber, therefore, the nitrogen vaporized in the preserving vessel is cooled by the cooling part of the Stirling refrigerator in the condensing chamber and liquefied again, and so this liquid nitrogen can be reused for cooling the preserving vessel. Moreover, since the preserving vessel can be cooled by the liquid nitrogen when performing maintenance on the Stirling refrigerator, the specimens in the preserving vessel can always be cooled at a predetermined temperature or lower.
摘要:
An improved freezer and plant gas system that harnesses the cooling properties of the plant gas evaporator to facilitate energy and cryogen savings, as well as the automation and optimization of a plant thermal processing system. The freezer preferably includes an internally mounted evaporator sized to meet the gas requirements of the plant processes requiring inert gas. By evaporating the plant gas in the freezer, the freezer can be remotely located from the liquid cryogen source while still making liquid cryogen available when called for during a cryogenic treatment process metal or other materials. In addition, by evaporating in the freezer the freezer is able to harness the cooling properties of the evaporator to pre-cool the freezer and material prior to use of liquid in the cooling cycle. Alternatively, a liquid load basket is adapted to economically thermally treat materials in a deep cryogenic treatment.
摘要:
An apparatus for subjecting articles of manufacture to a cryogenic thermal cycling process includes a bottom portion and a lid. The bottom portion comprises an outer and inner tank separated by a plurality of insulation layers. The inner tank defines an inner cavity wherein the articles are subjected to the cryogenic process. A thermal break is provided between the lid and bottom portion so that the temperature of the inner cavity does not conduct to the outer tank of the apparatus bottom portion. The process conducted in the apparatus is controlled by a pre-programmed profile inputted by a key controller or PC. Liquid nitrogen is the preferred cryogenic material to be employed. The novel process subjects the article to extreme negative temperatures thereafter cycling the article between a set of negative temperatures for a number of cycles. The process is completed by heating the article to an extreme positive temperature and then allowed to cool to ambient room temperature. The novel cryogenic thermal cycling process strengthens the article by realigning its molecular structure to eliminate micro-cracking and other manufacturing deforming characteristics.
摘要:
A treatment chamber for a charge comprises at least oen door, internal walls delimiting a treatment space, passages for the recirculation of gas, and apparatus for circulating gases in the treatment space and the passages. The circulating apparatus extracts the gases from the treatment space (4) and sends them through the passages (9,9'). The chamber is provided with injectors (12) for cryogenic fluid and an outlet (16) for evacuation of gas. The injectors are at least one nozzle (12) to spray liquid nitrogen or carbon dioxide and are disposed adjacent the circulating apparatus, which is in the form of a fan (8), the injectors (12) being directed toward the inlet of this fan. In the corresponding treatment process, a cryogenic gas is circulated through the charge, a cryogenic fluid e.g. liquid carbon dioxide or liquid nitrogen is injected into the gas flow leaving the charge, and the cooled gas is recirculated so as to cause it to pass again through the charge in the same direction. All contact between the gas and the charge is prevented during its recirculation.
