Described herein are methods for making clear ice. In one embodiment, a method for making clear ice includes providing a mold of any of the embodiments described herein, optionally inserting a skewer through the mold, the skewer being coupled to an item; circulating, using fluid inlet and outlet valves, a fluid in a mold cavity defined by the mold; varying overtime one or both of: a temperature of the cooling apparatus or a fluid flow rate, through the fluid inlet valve, as a percentage of max flow; and optionally retracting the skewer when the ice formation encases at least a portion of the item. In some embodiments, the method optionally includes a period of flow reversal, such that the fluid inlet valve becomes the fluid outlet valve and the fluid outlet valve becomes the fluid inlet valve. In some embodiments, the method optionally includes releasing the ice from the mold.

An ice luge mould (1), the mould (1) comprising a first part (2) and a complementary second part (3), the first part (2) and the second part (3) being configured to form an internal cavity therebetween when assembled, the mould (1) further comprising a water inlet (20) and a fluid-tight seal (21, 31) provided around the periphery of the first part (2) and second part (3) and a channel-forming means (32) configured to form a channel in the ice luge.

An ice making assembly includes an ice mold defining a mold cavity and a refrigeration loop having an evaporator in thermal communication with the ice mold. A compressor is operably coupled to the refrigeration loop for circulating a flow of refrigerant through the refrigerant loop to cool the evaporator and the ice mold. After ice is formed, a flow regulating device may divert a portion of the flow of refrigerant around the condenser through a bypass conduit to slowly increase a temperature of the refrigerant within the evaporator.

The disclosure provides a freezing device for freezing a liquid mixture and a method using the same. The freezing device includes a container and a tray removably disposed in the container. The tray has a tray plate disposed above a container bottom wall and has a plurality of spaced-apart receptacles for receiving the liquid mixture. When liquid nitrogen is introduced into a region between the tray plate and a container bottom wall, the liquid mixture received in the receptacles is solidified by the liquid nitrogen and is formed into shaped solid coolant pieces.

To provide an ice making device including an ice making tray, a drive unit configured to turn over the ice making tray, a frame including a frame body, the frame configured to support the ice making tray, and a fan motor configured to send wind to the ice making tray. The frame includes a block unit configured to contact a part of the ice making tray turning over to partially disturb the turning over of the ice making tray, and the fan motor is fixed only to a first frame part including one of a plurality of frame parts constituting sides surrounding a periphery of the ice making tray in a plan view of the frame.

The present invention provides a clear ice barrier device used with a container and an ice mold that has a plurality of openings for making clear ice. The clear ice barrier device comprises a body member to be received within a container featuring a plurality of support members that hold the body member at a desired position within the container, with a plurality of holes in the body member arranged to permit flow of water from the ice mold to the container.

An icemaker for making clear ice shapes using a process that removes and replenishes a freezable liquid, such as water, from and to one or more ice-mold cavities during freezing of the freezable liquid in the ice-mold cavity(ies). This process removes air bubbles from the freezable liquid during freezing that would otherwise result in cloudy ice. In some embodiments, the icemaker includes a suction system to draw freezable liquid from the cavity(ies) and a replenishment system to replenish the cavity(ies) with freezable liquid to replace the freezable liquid that the suction system draws out of the cavity(ies). In some embodiments, the replenishment includes a reservoir containing freezable liquid and the suction system includes a pump that draws the freezable liquid from the cavity(ies) and discharges it to the reservoir. Methods of making clear ice and other systems for making clear ice are also disclosed.

The invention encompasses methods for the large-scale (preferably under cGMP or cGLP standards) preparation of micron-sized or submicron-sized particles including pharmaceutical or biologic active agents. The systems and methods include a cryogenic cooling system including a novel shroud that enhances the cooling effects thereby reducing product loss and increasing product yields.

An ice making assembly includes a central hub rotatably mounted within a chilled chamber. A mold assembly is attached to the central hub and includes an ice mold that is pivotally coupled to a yoke and defines a mold cavity for receiving water. A drive mechanism rotates the central hub by accelerating the central hub until the rotation speed reaches a target speed and periodically reducing the rotation speed of the central hub to a reduced speed before accelerating back to the target speed until an ice billet is formed.

A method of and apparatus for accelerating the cooling of a beverage can and/or ice tray utilizing at least one body that presents a density and thermal conductivity, defines a standard beverage can and/or ice tray receiving receptacle configured to form a minimum contact surface area of engagement with at least one can and/or tray, and preferably further defines a series of thru-holes, so as to promote accelerated cooling through conduction, convection within a compartment.
