A cryogenic freezing tunnel having a conveyer belt, insulated panels, each panel comprised of an inner metal surface layer, a wooden layer, a foam insulation layer, an outer metal surface layer, and tie pins connecting the outer and inner metal surface layers together, thereby, preventing void spaces between the inner metal layers and the wooden layers of the panels, which leads to ice build-up and bulging of the inner metal surface which forces collection pans and conveyer belt supports mounted on top the inner metal surfaces upward into the conveyer belt and consequently causes damage to the collection pans, conveyer belt supports, and conveyer belt.
