An ice making assembly within an appliance with a housing having an inlet and an outlet, and a lower portion and an upper portion. The assembly includes a rotatable shroud within the housing with a first slot in air communication with the inlet, and a second slot in air communication with the outlet. A thermoelectric device with a top side and a bottom side, and having a heat sink on the bottom side between the first slot and the second slot. An ice tray disposed above and thermally connected with the top side, a barrier wall within the housing and in contact with the shroud between the lower portion and the upper portion.

The present teachings provide an approach for energy efficient creation of dilute sterile fluids such as ready-to-drink beverages. To achieve such creation, a beverage processing apparatus may have a sterile liquid concentrate source connected to deliver sterile liquid concentrate and a sterile water source having an inlet connected to receive water and a cold water filter sterilizer connected to the inlet. The apparatus may also have a dilute fluid outlet and an aseptic mixing component. The aseptic mixing component may be interconnected between the sterile liquid concentrate source, the sterile water source and the dilute fluid outlet to: receive sterile liquid concentrate; receive sterile water; and to provide a dilute fluid.

Disclosed herein are embodiments of an energy recovery system for a freeze-drying system. In some embodiments, the freeze-drying system includes a freeze dryer chamber having one or more shelves disposed therein; a refrigeration system comprising a refrigerant condenser; a heat exchanger; a first fluid line to thermally couple the refrigerant condenser to the heat exchanger; and a second fluid line to thermally couple the one or more shelves to the heat exchanger.

The present application is related to a portable refrigeration apparatus for vaccines, food items, beverage containers, or any other item. The apparatus includes a refrigerated container comprised of a plurality of substantially identical chilling panels interconnected to form a sealed container that defines an internal volume, each of the chilling panels containing a cooling element. The refrigerated container encloses an internal storage space and has a generally modular design to facilitate packaging and transportation. The apparatus permits the internal storage space to maintain a temperature in the range of 4 C.8 C. for a long period of time following a loss of electrical power.

A control system and method for a frostless, multivariable coupling and heat pump-based hot blast stove are used for grain drying. A first heat exchanger, a second heat exchanger, a main solution pool, corresponding pipelines, and a temperature detector are configured in the control system. A first heat pump unit, a second heat pump unit and a third heat pump unit are formed. A preheating zone, a low temperature zone, a medium temperature zone and a high temperature zone are sequentially formed on an air supply pipeline from a fresh air inlet to a fresh air outlet. A frostless operation procedure is provided. Through the configuration, the control system and method for a frostless, multivariable coupling and heat pump-based hot blast stove can implement heat supply in a gradient heat-circulation preheating mode and a gradient heat-circulation frostless mode.

An ice making apparatus for an appliance includes a housing that has an interior volume and an ice tray horizontally suspended across the interior volume that is configured to retain water. The ice making apparatus also includes a heat pump thermally coupled to a bottom surface of the ice tray. The heat pump is configured to freeze water in the ice tray and expel heat. A heat transfer device is configured to move heat expelled by the heat pump to an upper portion of the interior volume.

A heat pump system is disclosed comprising a heat-exchanger extracting latent heat from liquid stored in a reservoir, thereby forming an ice slurry. The heat pump also includes a device for delivering the heat to a heat consumer. The heat pump system includes a random input of extrinsic liquid into the reservoir and a device for removing ice slurry stored in the reservoir outward the system.

A slender and funnel-shaped jet nozzle structure includes a plurality of slender tapered diversion channels, a plurality of slender jet nozzles and a conveyer belt. The wall thickness of the slender tapered diversion channel is 1-5 mm. The wall thickness of the slender jet nozzle is 1-5 mm. A thickness of the conveyer belt is 1-5 mm. The slender tapered diversion channel is a hollow slender truncated cone and includes an upper opening and a lower opening. The upper opening of the slender tapered diversion channel is substantively elliptic, and the lower opening of the slender tapered diversion channel is connected to an inlet of the slender jet nozzle. The slender jet nozzle is a hollow slender elliptic cylinder.

A food dehydration device which can dry comestibles as well as other items utilizing electric and/or solar power. Drying trays may be disposed vertically or horizontally. Units may be stacked vertically to expand capacity. For food storage, drying trays may fit into standard zip plastic bags, without need of unloading. Drying trays may be sized similar to standard dinner plates to fit more easily into dishwashers, over countertop cabinets. Variable venting resists rain and other liquids from the drying cavity. A hand-operated pusher device may be used to impale foods onto posts to load the drying trays. Trays may include orthogonal posts to impale and/or open-air suspend on the tips of posts, articles being dried, such as fruit rollup trays, yogurt cups, herbs, seeds, or nuts. Embodiments may be stored on their side to reduce storage shelf height requirements suitably including nonstick coating.
