Embodiment 1

[0040] see Figure 1-5, a quick-freezing machine for prepackaging aquatic products, comprising a tunnel-shaped shell 1, a conveying device 2, an air curtain assembly 10 installed inside the two ends of the shell 1, a sealing curtain 12 installed at the lower end of the air curtain assembly 10, and an air curtain The blower 11 connected to the assembly 10 , the air inlet 20 on the housing 1 , and the electric control box 21 fixedly connected to the housing 1 , and the conveying device 2 mainly send the prepackaged aquatic products into the interior of the housing 1 . The tunnel-type quick-freezing machine quickly freezes the pre-packaged products to effectively keep the products fresh. The air curtain assembly 10 blows air from the blower 11 to form an air curtain, which effectively prevents the nitrogen inside the casing 1 from overflowing, or the outside air enters the casing. 1, in the prior art, the air curtain is set also in order to reduce the nitrogen content in the work...

Abstract

The invention discloses an instant freezer for prepackaging aquatic products. The instant freezer comprises a tunnel-shaped shell, a conveying device, air curtain assemblies installed in the interiors of two ends of the shell, sealing curtains installed at the lower ends of the air curtain assemblies, an air blower connected with the air curtain assemblies, an air inlet in the shell and an electric control box fixedly connected to the shell, the bottom end of the interior of the shell is provided with roller columns rotationally connected to the two side walls of the shell, the conveying device is provided with a conveying chain, the lower end face of the upper half portion of the conveying chain abuts against the roller columns, the upper end face of the shell is fixedly connected with a supporting rod, and a transverse rod is hinged to the top end of the supporting rod. According to the instant freezer, due to the arrangement of baffles, the two ends of the shell are always in a closed state, leakage of nitrogen is reduced, when a product packaging box passes through, leakage generated through cooperation between the baffles can be collected through an air pump and an air storage tank and then refilled into the shell, and under the cooperation of the air curtains and the sealing curtains, the instant freezer effectively reduces nitrogen leakage.

Description

technical field [0001] The invention relates to the technical field of quick-freezing machines, in particular to a quick-freezing machine for prepackaging aquatic products. Background technique [0002] The quick-freezing machine is to freeze the center temperature of the quick-frozen items to -18° in a short period of time, and quickly pass through the ice crystal production belt (0 to -5 degrees) within 30 minutes to achieve the purpose of reducing the loss of nutrients and keeping the original taste. Quick freezer is a high-efficiency freezing equipment that can freeze a large amount of products in a short time. It can effectively and economically freeze a variety of products placed inside the quick freezer, such as various shapes of meat, fish, shrimp, meatballs, vegetables, prepared foods, dairy products, etc. [0003] Single tunnel type quick-freezing machines often use liquid nitrogen, which is inert, colorless, odorless, non-corrosive, non-flammable, and has an extr...
