摘要： An apparatus for reducing a temperature of products includes a housing having a chamber within, wherein the chamber has upper and lower regions; a conveyor for transporting the products through the chamber, the conveyor constructed for substantial gas flow to pass through the conveyor without substantially reducing the ability of the conveyor to transport the products; an agitator associated with the conveyor for selective, intermittent contact with the conveyor to displace the conveyor from a plane of travel, thereby displacing the products on the conveyor to substantially prevent the products from adhering to the conveyor and other of the products; a gas circulation device disposed within the chamber to generate circulating gas flow within the chamber; and a shroud disposed within the chamber for coacting with the conveyor to provide an interface between the upper and lower regions, the shroud constructed and arranged to guide the circulating gas flow from the lower region through the conveyor to the upper region, and thereby facilitating displacement of the products on the conveyor to increase exposed surface area of said products. A related method is also provided.

摘要： A method of reducing a temperature of at least one item including: transporting the at least one item on a moving substrate within an enclosure, the enclosure including at least one impingement apparatus; providing a coolant to at least one of a high pressure zone or a low pressure zone of the enclosure; circulating the coolant through the high and low pressure zones using a variable-speed gas circulation device of the impingement apparatus; directing impingement jets through openings in at least one impinger of the impingement apparatus toward the moving substrate disposed within the low pressure zone; and intermittently performing an operation on the at least one impingement apparatus during said transporting including: (i) reducing a speed of the variable-speed gas circulation device; (ii) vibrating the at least one impinger; and (iii) increasing the speed of the variable-speed gas circulation device.

摘要： An impinger for cooling or freezing products includes an impingement plate containing openings for directing impingement jets of a mixture of gas and solid or liquid cryogen toward the products transported on a conveyor, wherein the openings in aggregate have an open area of about 7% to about 12% of the total surface area of the impingement plate, the impingement plate providing a back pressure restriction of about 220 to about 475 Pa. A process for cooling or freezing products within a housing chamber includes transporting the products, particularly IQF food products, on a moving substrate within the chamber, mixing a gas with solid or liquid cryogen to form a mixture, directing the mixture to the aforementioned impinger; and selectively directing the pressurized impingement jets of the mixture from the impingement plate toward the products transported on the substrate.

摘要： Disclosed are an in-line direct cryogenic method and system for cooling heated fluid food products, such as sauces. The method includes injecting cryogen directly into the fluid to be cooled while the flow rate of the fluid to be cooled is adjusted in response to downstream temperature measurements and while maintaining the injection rate of the cryogen into the fluid. According to the method the flow of the sauce is adjusted during the flow of the cryogen to achieve process stability, product uniformity and efficient use of the cryogen.
