摘要： The present invention is a combination immersion/impingement tunnel freezer. A solid conveyor belt moves the items to be frozen through an initial immersion section wherein the conveyor belt is immersed in a bath of liquid refrigerant. Subsequently, the conveyor belt moves the items to be frozen through an impingement section wherein the evaporated refrigerant from the immersion section is directed toward the solid conveyor belt at a high velocity and at an angle substantially perpendicular to the longitudinal axis of the tunnel.

摘要： The present invention is a tunnel freezer which incorporates a "dual flow" design whereby the refrigerant is introduced at each end of the tunnel and withdrawn from the middle of the tunnel. A key to the present invention is that the dual flow design allows one to confine the pressure gradient for leaks between the ends of the tunnel where it will not be a concern since the item entrance and exit ports (which ports provide a ready access for leaks) are located at the ends of the tunnel.
摘要翻译： 本发明是一种结合了“双流”设计的隧道式冷冻机，其中制冷剂被引入隧道的每一端并从隧道的中部撤出。 本发明的关键在于，双流设计允许在隧道的端部之间限制泄漏的压力梯度，因为物品的入口和出口（这些端口提供便于泄漏的通路） ）位于隧道的两端。
