Standalone and self-contained cooling systems using compressed liquid and/or gas CO.sub.2 containers positioned in an insulated or non-insulated vessel and consisting of a specially designed unit where the containers are vertically positioned in an upright or upside-down position.

The liquid and/or gas CO.sub.2 coolant is then released into capillary tube(s) embedded into a heat transfer plate or heat exchanger thus leveraging the CO.sub.2 coolant properties.

The temperature is controlled by a metering CO.sub.2 releasing system encompassing an electronic control device which can be operated remotely and/or via a touch screen and which sends alerts when pre-defined thresholds are exceeded.

The invention's metering CO.sub.2 releasing system may be triggered by an electronic or a thermostatic valve or may be triggered manually or by an electronic solenoid. The invention's cooling system also encompasses check valves, which avoid liquid and/or gas CO.sub.2 from escaping when removing or replacing CO.sub.2 containers individually.

There is disclosed a plate freezer apparatus. The plate freezer apparatus comprises a first frame member configured to support a plurality of vertically disposed freezing plate members arranged to define a freezing cavity therebetween and a flooring system configured to extend below the freezing plate members to form a base for the freezing cavities, wherein the flooring system is configured to be raised so as to lift any frozen material present in freezing cavities out of the freezing cavities so that the frozen material extends from the freezing cavities to project above an upper edge of the freezing plate members. A second frame member is mounted above said first frame member so as to extend substantially a length of the first frame member, the second frame member having a plurality of paddle members mounted therein that are individually actuable to extend between a horizontal axis where the paddle members extend substantially parallel with the second frame member, and a vertical axis where the paddle members extend from the second frame member to be received between the frozen material raised from the freezing cavities. The first frame member further comprises a lifting mechanism adjacent a proximal end thereof, the lifting mechanism being actuable to raise the proximal end of the first frame member so as to tilt the first frame member towards a distal end and wherein the paddle members are actuable to facilitate controlled release of the frozen material such that upon release the frozen material is able to slide along the upper edges of the plates and off the distal end of the first frame member for collection.

A cryogenic dynamic cooling apparatus and a cooling method for heat assisted magnetic recording media substrate are provided. The cooling apparatus includes a chamber that is configured to receive a substrate. A substrate holder secures the substrate inside the chamber. The apparatus has a cooling plate that is movable between a retracted position and an extended position inside the chamber. The cooling plate provides clearance for movement of the substrate holder inside the chamber in the retracted position, and the cooling plate cools the substrate in the extended position. Also, the cooling plate is substantially parallel to and spaced apart from the substrate. The apparatus further includes a cryogenic operatively coupled to the cooling plate that is cooled by the cryogenic cooling element.

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 heat conducting plate and a method for producing a plate body thereof. The heat conducting plate comprises an integrally formed plate body. The plate body comprises a front surface, and several capillary tube cavities formed in the plate body and allowing flow of a heat exchange medium. Each capillary tube cavity extends along a first direction parallel to the front surface, and a micro-tooth structure is provided on the inner wall of each capillary tube cavity. The heat exchange medium may flow in the capillary tube cavities along the first direction. By means of the plate body and the capillary tube cavities, the temperature homogenizing effect and heat exchange efficiency of the heat conducting plate are significantly improved; by providing the micro-tooth structure, the heat exchange medium may form a capillary phenomenon, thereby improving the heat exchange efficiency.
