Problems solved by technology

[0006]In addition, the existing tunnel quick-freezing machines need to consume a lot of liquid nitrogen, whether it is quick-freezing poultry, beef, pork, grains, or shelled fruits. From the perspective of efficiency, one ton of frozen products needs about 1.5 tons of liquid nitrogen, and the price of liquid nitrogen is 600-1000 yuan / ton according to seasonal factors, which is the main consumption of consumables

Abstract

The invention belongs to the field of cold chain equipment, and discloses a tunnel type instant freezer for poultry. The tunnel type instant freezer comprises a tunnel body, wherein a conveying belt and spray heads located above the conveying belt are arranged in the tunnel body; and a plurality of frames for fixing poultry in an inverted mode and pulling open body cavities of the poultry to be right opposite to the spray heads are arranged on the conveying belt. According to the tunnel type instant freezer for poultry, the poultry does not need to be specially pre-cooled when being quick-frozen by the instant freezer, so that the consumption of liquid nitrogen can be effectively reduced.

Description
