A process and system in which solid droplets of a lipid product are prepared. The liquid lipid product is introduced into a freeze tunnel by one or more nozzles so as to form droplets of the liquid product. The droplets are introduced onto a conveyor belt at a first end of the freeze tunnel. The freeze tunnel is at a temperature sufficient that the droplets assume a semisolid state on or before contacting the conveyor belt and then become solid droplets as they pass through to a second end of the freeze tunnel.

Systems and methods for an actively cooled container comprising: a power subsystem; an active cooling subsystem; and a control subsystem are provided. In some embodiments, the control subsystem is configured to: determine that additional cooling is needed; cause the active cooling subsystem to cool the actively cooled container below a lower limit; determine to end the additional cooling; and cause the active cooling subsystem to cool the actively cooled container at or above the lower limit. In this way, the best balance between a fast cooldown time and not damaging (e.g., through freezing) the product load (e.g., beverages), is achieved.

The present invention is directed to a system (100) maintaining chilled temperature in a cold storage (102) comprising: a plurality of coolant layers 104 uniformly placed on the roof of said storage (102); each coolant layer comprising multiple coolant plates (106) stacked in rows and columns; a compressor (110) generating airflow and circulating airflow in a circular pattern from top to bottom in said (storage 102); thereby maintaining temperatures in the range −25° C. to +25° C. in said storage; said plurality of coolant layers (104) being placed in close proximity to said compressor (110) for effectively circulating airflow; a coolant holder frame (108) for uniformly adjusting said multiple coolant plates (106) in said plurality of coolant layers (104), and allowing efficient airflow from top to bottom in said storage (102); base of said storage being provided with, holes (112), throughout for sucking the air circulated by said compressor (110) to improve the circulation of airflow in said storage (102); and said storage (102) being insulated to increase the thermal insulation coefficient to maintain the desired temperature in said storage, thereby freezing said coolant layers.

A control method of a refrigerating and freezing device and a refrigerating and freezing device are provided. The refrigerating and freezing device includes a cabinet defining a storage compartment. The control method includes a refrigerating operation step, a foodstuff determining step, and a cooling operation step. The refrigerating operation step is to control a temperature of the storage compartment to be within a first preset temperature range. The foodstuff determining step is to determine whether a new foodstuff is put into the storage compartment. The cooling operation step is to, when a new foodstuff is put into the storage compartment, cool the storage compartment. Since the temperature of the new foodstuff is greater than that of the original foodstuffs in the refrigerating and freezing device, cooling the storage compartment changes a storage temperature suitable for the foodstuffs originally stored in the storage compartment into a storage temperature suitable for the foodstuffs originally stored in the storage compartment into a storage temperature suitable for the new foodstuff, and the storage temperature is more convenient for the preservation of the new foodstuff and ensures good storage conditions for the newly put foodstuff. Furthermore, the preservation effect on the original foodstuffs will not be affected, and the preservation effect of the refrigerating and freezing device on the foodstuff is enhanced.

An instant freezer apparatus able to freeze consumable fluids and food having a freezing point lower than water is disclosed. The apparatus and method of the present invention is directed to a freezer typically able 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.

This invention describes a device that is able to promote the rapid cooling/freezing of liquids and pasty and solid foods in general, where it is formed by several components that enable the action of cooling/freezing. Additionally, this invention describes that this device can incorporate the additional function of a refrigerator, through direct coupling of a thermal box to the cooling system of the device.
