Abstract
A method for reducing a temperature of a product in a freezer includes providing a product to a chamber of the freezer; dividing a portion of the chamber disposed between a pair of baffle assemblies in the freezer into an intake zone and an outflow zone; moving each baffle assembly of the pair of baffle assemblies in the chamber 90° degrees out of phase with each other for directing a gas flow in the chamber; oscillating the gas flow within the chamber between the intake zone and the outflow zone during the moving the pair of baffle assemblies; injecting a cryogen substance into the chamber for cooling the gas flow; and contacting the product with the cooling gas flow.
