Embodiment 1

[0040] see Figure 1-5, a quick-freezing machine for pre-packing aquatic products, comprising a tunnel-shaped casing 1, a conveying device 2, an air curtain assembly 10 installed inside both ends of the casing 1, a sealing curtain 12 installed at the lower end of the air curtain assembly 10, and the air curtain The blower 11 connected to the assembly 10 , the air inlet 20 on the casing 1 , and the electric control box 21 fixedly connected to the casing 1 , the conveying device 2 mainly feeds the prepackaged aquatic products into the casing 1 . The tunnel-type quick-freezing machine quickly freezes the pre-packaged products, effectively keeping the products fresh. The air curtain assembly 10 blows the blower 11 to form an air curtain, which effectively prevents the nitrogen inside the casing 1 from overflowing or the outside air entering the casing. Inside 1, in the prior art, an air curtain is installed to reduce the nitrogen content in the working environment and reduce the l...

Abstract

The invention discloses a quick-freezing machine for pre-packing aquatic products, comprising a tunnel-shaped casing, a conveying device, an air curtain assembly installed inside both ends of the outer casing, a sealing curtain installed at the lower end of the air curtain assembly, and an air curtain connected to the air curtain assembly. A hair dryer, an air inlet on the casing, and an electric control box fixedly connected to the casing, the bottom end inside the casing has rollers rotatably connected to the two side walls of the casing, and the conveying device is provided with a conveying chain, The lower end surface of the upper half of the conveying chain is in contact with the roller column, the upper end surface of the casing is fixedly connected with a support rod, and the top end of the support rod is hinged with a transverse rod. In the present invention, the baffles are arranged so that the two ends of the shell are always in a closed state, reducing the leakage of nitrogen gas. When the product packaging box passes through, the leakage caused by the cooperation between the baffles will be collected by the air pump and the air storage tank, and the leakage will be recovered. Filled into the shell, with the cooperation of the air curtain and the sealing curtain, the device can effectively reduce the leakage of nitrogen.

Description

technical field [0001] The invention relates to the technical field of quick-freezing machines, in particular to a quick-freezing machine for pre-packing aquatic products. Background technique [0002] The quick-freezer is to freeze the center temperature of the quick-frozen items to -18° in a short time, and quickly pass through the ice crystal production zone (0 to -5 degrees range) within 30 minutes to achieve the purpose of reducing the loss of nutrients and reducing the loss of nutrients. A quick freezer is a high-efficiency freezing device that can freeze a large number of products in a short period of time. A wide variety of products, such as meat, fish, shrimp, meatballs, vegetables, prepared foods, dairy products, etc., in various shapes, can be frozen efficiently and economically. [0003] Single tunnel type quick-freezers often use liquid nitrogen, liquid nitrogen, which is inert, colorless, odorless, non-corrosive, non-flammable, and has extremely low temperatur...
