Problems solved by technology

In order to improve the freezing efficiency and reduce the consumption of liquid nitrogen, this type of tunnel freezer must minimize the space of the tunnel and ensure the airtightness of the tunnel as much as possible, which will make it inconvenient to clean the tunnel, conveyor belt, and liquid nitrogen nozzle. If the tunnel is not cleaned cleanly, the quality of subsequent frozen aquatic products will be reduced

Example Embodiment

[0029] The present invention will be further described below in conjunction with the drawings and embodiments.

[0030] In the embodiment, such as figure 1 , figure 2 , image 3 As shown, a split type liquid nitrogen tunnel freezer includes a body and a quick-freezing tunnel 3. One end of the quick-freezing tunnel 3 is provided with a material inlet 4, and the other end is provided with a material outlet 5, between the material inlet 4 and the material outlet 5 A conveyor belt 6 with adjustable speed is provided. The body is also provided with a liquid nitrogen inlet 7, a tail gas outlet 8, a uniform temperature fan 9, and a tail gas fan 10; the body includes a lower base 1 and an upper body 2 with adjustable height The upper body 2 has a first position to be closed with the lower frame 1 to form the quick-freezing tunnel 3, and a second position to be separated from the lower frame 1 to open the quick-freezing tunnel 3; The conveyor belt 4 is installed in the quick-freezing tun...

Abstract

The invention discloses a split type liquid nitrogen tunnel freezer, which is mainly a freezer freezing tunnel that is convenient to clean. The freezer is characterized by comprising a lower support, and an upper body with an adjustable height; the upper body is provided with a first position and a second potion, the first position is used to close the upper body and the lower support to form a freezing tunnel, and the second position is used to separate the upper body and the lower support so as to open the freezing tunnel. The lower support is provided with a plurality of elevating apparatuses for adjusting the height of the upper body and an elevation driving device. A conveying belt comprises a hanging device and an installation rack. When the upper body is positioned on the first position, the conveying belt is placed on the lower support through the installation rack. When the upper body is positioned on the second position, the conveying belt is hung on the upper body through the hanging device. The upper body and the lower support can be separated; the height of the upper body can be adjusted through the elevating apparatuses, the freezing tunnel can be opened or closed automatically, thus the interior of the freezer can be washed and maintained easily; and moreover, the conveying belt can be removed from the lower support and radically washed.

Description

technical field [0001] The invention relates to the field of freezing equipment, in particular to a split-type liquid nitrogen tunnel freezer for quick freezing of aquatic products. Background technique [0002] With the improvement of living standards, people's demand for aquatic products is increasing, and due to the existence of aquatic product fishing seasons and closed fishing seasons, fresh aquatic products cannot meet people's needs, so frozen aquatic products occupy a large market share. Important position. In order to ensure the quality of frozen aquatic products, the quick-freezing process is mostly adopted, using ammonia, freon or liquid nitrogen for refrigeration. Liquid nitrogen refrigeration can quickly freeze the product and pass through the ice crystal formation zone, preventing the formation of large ice crystals in the food cells and damaging the cell wall. It can better maintain the original flavor and quality of the product, and has obvious environmental...
