Description

Technical Field

[0002] As we all know, in order to preserve freshness and quality, some foods need to be frozen before transshipment or transportation. For the transshipment of these frozen foods, specific transshipment equipment or devices are usually required. Frozen foods include quick-frozen dumplings, quick-frozen buns, quick-frozen steamed buns, quick-frozen meat and other food types. Usually, during the production process, the food that has been automatically or manually processed needs to be frozen before packaging. The freezing needs to be achieved in the form of a freezing tunnel. There is a conveying mechanism such as a conveyor belt in the freezing tunnel to drive the movement of the food, and the food is packaged from the exit of the freezing tunnel.

[0003] When the filling is transported in the conveying device, cooling water is usually passed through the cooling trough or nitrogen formed by liquid nitrogen gasification is used to transfer the filling at a low temperature. However, the filling is generally piled up in a lump during transportation. Generally, only the surface of the filling is effectively cooled, while the inside of the filling cannot be cooled well, so that the low-temperature transportation of the filling does not achieve the expected effect. When transporting food fillings, auger conveying or conveyor belt conveying is generally the main method. Both of these conveying methods will cause part of the filling to stick to the surface of the auger or conveyor belt. At this time, the staff is required to clean the conveying device regularly, otherwise it will affect the subsequent filling transportation over time, and also increase the loss of filling during the transportation process.

A turntable 360 ​​is fixedly connected to the outside of the transfer box 220, and a movable column 370 is fixedly connected to the edge of the turntable 360 ​​away from the first rotating shaft 230. A movable frame 380 is movably connected to the outer side of the movable column 370. The center of the bottom of the movable frame 380 is fixedly connected to the top of the piston rod 340. A liquid nitrogen box 3910 is installed on the other side of the top of the upper U-shaped cover plate 130. A liquid nitrogen pipe is fixedly connected to one side of the liquid nitrogen box 3910, and a liquid nitrogen pump 3920 is installed at one end of the liquid nitrogen pipe. A nitrogen tank 3930 is installed on the top of the liquid nitrogen pump 3920.

[0021] As the first rotating shaft 230 rotates, the rotating disk 360 rotates synchronously, thereby driving the movable column 370 to make a circular motion, driving the movable frame 380 to start to make an up and down reciprocating motion, thereby driving the piston rod 340 and the piston 350 to make a reciprocating pulling and pulling motion in the piston cylinder 330. When the piston rod 340 drives the piston 350 to move toward the top of the piston cylinder 330, a negative pressure is generated in the piston cylinder 330, and the one-way valve cooperates to start extracting nitrogen from the nitrogen tank 3930. The nitrogen enters the piston cylinder 330 through the first connecting pipe 390. When the piston rod 340 drives the piston 350 to move toward the bottom of the piston cylinder 330, a part of the nitrogen in the piston cylinder 330 is squeezed and transported to the inner wall of the cooling cylinder 310 through the one-way valve. The nitrogen enters the first spiral tube 315, the second spiral tube 316 and the third spiral tube 317 through the connecting hose 320 and the connecting tube 318, respectively, and the filling in the arc-shaped chamber between the cooling cylinder 310, the first sleeve 311 and the second sleeve 312 is cooled and treated at low temperature. By using this layered chamber, the filling is well cooled. The filling is broken up into layers, and the inside of the filling is also fully treated with low temperature. At the same time, as the filling is transported downward, when passing through the bottom of the cooling cylinder 310, the filling falls like noodles in cooperation with the feeding hole 314 at the bottom of the cooling cylinder 310. After the nitrogen flows out from the ends of the first spiral tube 315, the second spiral tube 316 and the third spiral tube 317, the filling like noodles below is further cooled and treated with low temperature.

[0022] Please refer to Figure 2 and Fig. 9As shown, the coating component 500 includes a second rotating shaft 510 horizontally arranged in the lower U-shaped cover plate 140, and a plurality of groups of circumferentially distributed fixed plates 520 are fixedly connected to the outside of the second rotating shaft 510, and a brush 530 is fixedly installed at the end of each group of fixed plates 520 away from the second rotating shaft 510. An oil-proof paper 550 is sleeved on the outside of the conveyor belt 110, and an oil storage box 560 is placed at the bottom of the inner cavity of the lower U-shaped cover plate 140 below the conveyor belt 110. One end of the second rotating shaft 510 extends through the outside of the lower U-shaped cover plate 140 and is fixedly sleeved with a pulley on the outer wall of the output end of the first motor 120, and the two groups of pulleys are connected by a belt 540. When each group of brushes 530 rotates to the highest point, it contacts the bottom of the conveyor belt 110, and a cellulose oil-proof agent is added to the oil storage box 560.

[0023] The second rotating shaft 510 is driven to rotate by the transmission of the conveyor belt 110 and the belt 540, thereby driving a plurality of groups of circumferentially distributed fixed plates 520 and brushes 530 to rotate and make circular motions. When the brush 530 rotates to the bottom, it contacts the cellulose oil-proofing agent in the oil storage box 560, so that the cellulose oil-proofing agent adheres to the brush 530. When the brush 530 rotates to the highest point, it contacts the bottom of the conveyor belt 110, and the cellulose oil-proofing agent is applied to the surface of the oil-proofing paper 550 on the outer wall of the conveyor belt 110, so that the surface of the oil-proofing paper 550 always has the cellulose oil-proofing agent, which prevents the filling from adhering to the surface of the conveyor belt 110 during transportation and transfer, thereby reducing the occurrence of filling damage and further reducing the loss of filling during transportation.

[0024] Please refer to Figure 2 and Figure 8 As shown, the material distribution assembly 400 includes a cylinder push rod 410 fixedly mounted on one side of the upper U-shaped cover plate 130, the output end of the cylinder push rod 410 extends through the interior of the upper U-shaped cover plate 130 and is fixedly connected to a mounting plate 420, a blade 430 is fixedly connected to the side of the mounting plate 420 away from the output end of the cylinder push rod 410, a connecting block 440 is fixedly mounted on the bottom end of the outer wall of the fixed tube 3970, a fixing rod 450 is fixedly mounted on one end of the connecting block 440, a knife groove matching the blade 430 is provided on the side of the fixing rod 450 close to the blade 430, two groups of guide columns 460 are fixedly mounted on one side of the inner wall of the upper U-shaped cover plate 130, the other ends of the two groups of guide columns 460 are fixedly connected to the two ends of one side of the fixing rod 450 and penetrate through the two ends of the mounting plate 420, and the two ends of the mounting plate 420 are slidably connected to the two groups of guide columns 460.

[0025] The working time interval value of the cylinder push rod 410 is set so that the cylinder push rod 410 operates intermittently. The output end of the cylinder push rod 410 pushes the blade 430 to cooperate with the knife groove on the fixed rod 450 to cut the falling fillings, so that the fillings maintain a certain volume when falling onto the conveyor belt 110. Through the two sets of guide columns 460, the movement of the blade 430 is more stable.

[0026] Please refer to Figure 1 and Figure 2 As shown, sealing doors 150 are provided at both ends of the conveying rack body 100, and a relatively closed space is formed between the two sets of sealing doors 150 and the upper U-shaped cover plate 130 and the lower U-shaped cover plate 140.

A relatively closed space is formed between the two sets of sealing doors 150 and the upper U-shaped cover plate 130 and the lower U-shaped cover plate 140. On the one hand, the loss of nitrogen is reduced. On the other hand, the interior of the conveyor is placed in a relatively oxygen-free and low-temperature environment, which reduces the activity of microorganisms on the surface of the filling and increases the shelf life of the filling.

[0028] When in use, along with the rotation of the first rotating shaft 230, the rotating disk 360 is driven to rotate synchronously, thereby driving the movable column 370 to make a circular motion, driving the movable frame 380 to start to make an up and down reciprocating motion, thereby driving the piston rod 340 and the piston 350 to make a reciprocating pulling and pulling motion in the piston cylinder 330. When the piston rod 340 drives the piston 350 to move toward the top of the piston cylinder 330, a negative pressure is generated in the piston cylinder 330, and the one-way valve starts to extract nitrogen from the nitrogen tank 3930. The nitrogen enters the piston through the first connecting pipe 390. When the piston rod 340 drives the piston 350 to move toward the bottom of the piston cylinder 330, the nitrogen in the piston cylinder 330 is squeezed and transported to the inner wall of the cooling cylinder 310 through the one-way valve. The nitrogen enters the first spiral tube 315, the second spiral tube 316 and the third spiral tube 317 through the connecting hose 320 and the connecting tube 318, respectively, and the filling in the arc-shaped chamber between the cooling cylinder 310, the first sleeve 311 and the second sleeve 312 is cooled and treated at low temperature. , the filling is well layered and broken up, and the inside of the filling is also fully treated with low temperature. At the same time, as the filling is transported downward, when passing through the bottom of the cooling cylinder 310, the filling is made to fall like noodles in cooperation with the feeding hole 314 at the bottom of the cooling cylinder 310. After the nitrogen flows out from the ends of the first spiral tube 315, the second spiral tube 316 and the third spiral tube 317, the filling like noodles below is further cooled and treated with low temperature. At the same time, another part of the nitrogen is transported to the plurality of branch pipes 39 through the second connecting pipe 3940. 50 and is sprayed out by the nozzle 3960, and nitrogen is sprayed into a relatively closed space formed by the two sets of sealing doors 150 and the upper U-shaped cover plate 130 and the lower U-shaped cover plate 140, so that the space is filled with low-temperature nitrogen, which further improves the cooling and low-temperature transportation effect of the filling, reduces the activity of microorganisms on the surface of the filling, and thus achieves the purpose of slowing down the loss of microorganisms, while ensuring the freshness of the filling for a long time. The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology.
