A food freezer includes: a first housing having a first chamber arranged internally within for providing a freezing gas to a food product within the first chamber; a second housing having a second chamber arranged internally within and being in fluid communication with the first chamber for exhausting the freezing gas from the first chamber; an adjustable opening disposed at a common wall between the first chamber and the second chamber for controlling a flow of the freezing gas moving from the first chamber to the second chamber, the adjustable opening disposed to provide a flow path for the flow of the freezing gas to a region of the second chamber for exhaust from said second chamber to an area external to the first housing and second housing; and a pressure curtain comprising the exhaust and disposed at the second chamber to prevent atmosphere from the area external to the first housing and second housing from entering said housings. A related method of exhausting freezing gas is also provided.

An impingement apparatus associated with a conveyor includes: (a) a shell supporting an impinger; and (b) a coolant delivery apparatus enclosed by the shell, the coolant delivery apparatus including a gas circulation device for directing a coolant to the impinger; the impinger including: (i) an impingement plate including openings for directing impingement jets toward the conveyor; (ii) at least one non-circular cam in mechanical communication with the at least one conveyor and rotatable when the conveyor is in motion; and (iii) at least one connector in mechanical communication with the at least one cam and the impingement plate, the connector displaceable during rotation of the at least one cam to elevate and lower the impingement plate.

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.

An apparatus and method for processing products by chilling or freezing includes a conveyor for conveying the products along a plane of travel; lifting means disposed for intermittent contact with the conveyor during processing; cam means rotatable for contacting and displacing the lifting means to contact and displace the conveyor from the plane of travel, thereby displacing the products on the conveyor to prevent the products from adhering to the conveyor and other of the products; and drive means operatively associated with the cam means to impart rotational movement to the cam means for intermittently contacting and displacing the lifting means.
