[0002] With the popularization and development of pre-prepared and convenient foods, soup products have also evolved from the original combination of packaged seasonings and concentrated oil packets to freeze-dried products.

[0003] The production of freeze-dried soup cubes requires that the soup be boiled and concentrated, then poured into a container, and then frozen and vacuum dried to extract the water to form freeze-dried soup cubes. After being soaked in water, the freeze-dried soup cubes will be restored to the corresponding soup, which is more convenient and quick to eat, has a long shelf life, and is easy to transport.

[0004] In the industrial production process of freeze-dried soup cubes, in order to ensure that the solid materials in the soup are evenly distributed in each soup cube, they are not placed directly in a compartmented container. Instead, the soup cubes are poured into a large container, and cut into small pieces after freezing and vacuum drying. However, after the freeze-dried production is completed, due to the lack of moisture, the texture is relatively crisp, and a large amount of residue or small pieces are easily lost during the cutting process.

DETAILED DESCRIPTION

[0017] The following is combined with Figure 1-6 This application is described in further detail.

[0018] The embodiments of the present application disclose a freeze-dried soup cube production line and process flow.

[0020] The first conveyor belt 1 is intermittently conveyed, and a plurality of material frames 11 for holding thick soup are installed on the upper surface. The injection pipe 2 is set above the first conveyor belt 1, and is used to inject the thick soup into the material frame 11. The partition frame 12 is a uniform grid-shaped frame structure composed of a plurality of vertical plates, which can be inserted into the material frame 11 and abut against the inner wall of the material frame 11 and divide the material frame 11 into a plurality of areas. The top of the partition frame 12 is higher than the top of the material frame 11, and lifting plates 121 abutting against the side walls of the material frame 11 are fixed on both sides. The upper surface of the lifting plate 121 is inclined, and an arc groove is opened on the lower surface. The bottom edge of the partition frame 12 is chamfered, and the inner wall of the material frame 11 is convexly arranged at the position opposite to the chamfer of the bottom of the partition frame 12 and can fit with the chamfered part of the material frame 11. The installation station 3 is set above the first conveyor belt 1, on the side of the injection pipe 2 facing the conveying direction of the first conveyor belt 1, and is used to install the partition frame 12 in the material frame 11. The material frame 11 is transported into the vacuum freeze-drying device at the end of the first conveyor belt 1 .

[0021] The second conveyor belt 6 is intermittently conveyed and is used to transport the material frame 11 transferred from the vacuum freeze-drying device. The turntable 4 is rotatably mounted on one side of the second conveyor belt 6 and driven to rotate by a motor. A plurality of station frames 41 are fixedly arranged at equal intervals on the circumferential outer wall of the turntable 4. The station frame 41 can be rotated to the top of the second conveyor belt 6. The station frame 41 is provided with an installation frame 42 for taking out the partition frame 12 in the lower material frame 11.

[0022] The third conveyor belt 7 is located on one side of the turntable 4 and is also intermittently conveyed. The installation frame 42 can be located above the third conveyor belt 7, and the placement component 8 is arranged above the third conveyor belt 7 to place the partition frame 12 on the third conveyor belt 7. The third conveyor belt 7 transports the partition frame 12 to the installation station 3 after passing through the ultrasonic cleaning area and the drying and sterilization area.

[0023] The first conveyor belt 1 drives the material frame 11 to move below the injection nozzle, and the injection nozzle injects the soup into the material frame 11 and spreads it evenly. Then the first conveyor belt 1 drives the material frame 11 to move to the installation station 3, and inserts the partition frame 12 into the material frame 11. The partition frame 12 divides the material frame 11 into multiple uniform spaces. Then the material frame 11 is transferred to the vacuum freeze-drying equipment at the end of the first conveyor belt 1 for freeze-drying. After freeze-drying, the material frame 11 is taken out and placed on the second conveyor belt 6 for conveyance. The second conveyor belt 6 drives the material frame 11 to move below the installation frame 42 and takes out the partition frame 12. The second conveyor belt 6 drives the material frame 11 to continue to move, and the freeze-dried soup cubes are taken out and the subsequent processes are carried out. After the turntable 4 moves the partition frame 12 to the top of the third conveyor belt 7, the partition frame 12 is placed on the third conveyor belt 7 through the placement component 8. The third conveyor belt 7 drives the partition frame 12 to move, and then after passing through the ultrasonic cleaning station and the drying and disinfection station, the partition frame 12 is transported back to the installation station 3 to realize the circulation of the partition frame 12 and the addition of the partition frame 12 to the freeze-dried soup cube production line. By adding the partition frame 12, the cutting process of the freeze-dried soup cube can be omitted, thereby reducing the debris and partial detachment generated in the cutting process of the freeze-dried soup cube, reducing product waste, and improving product quality.

[0024] refer to Figure 2The installation frame 42 is vertically slidably connected to the circumferential inner wall of the station frame 41. The station frame 41 is fixed with a first spring 411. The other end of the first spring 411 is fixedly arranged on the top of the installation frame 42, so that the installation frame 42 is completely located in the station frame 41. The first spring 411 is a tension spring. The bottom of the installation frame 42 is provided with a disengagement hole 421 at the position of the partition formed by the partition frame 12. The bottom of the installation frame 42 is fixedly provided with a plurality of guide cylinders 4211, and the guide cylinders 4211 are connected to the disengagement hole 421. A disengagement rod 4221 is slidably connected in the disengagement hole 421. The top of the disengagement rod 4221 is fixedly provided with the same extension plate 422. The bottom of the extension plate 422 is fixedly provided with a second spring 4222. The bottom end of the second spring 4222 is fixedly connected to the inner bottom wall of the installation frame 42. When the second spring 4222 is in a natural state, the bottom end of the disengagement rod 4221 is located in the guide cylinder 4211, and the disengagement rod 4221 can extend from the bottom of the guide cylinder 4211. The side walls of the installation frame 42 are vertically slidably connected with side blocks 43, and the side blocks 43 are located above the lifting plate 121 of the lower partition frame 12. A pulley 44 is installed on the top of the side wall of the installation frame 42, and a traction rope 431 is tied to the top of the side block 43. The traction rope 431 passes through the pulley 44 and is tied to the extension plate 422. The side block 43 can keep the traction rope 431 in an extended state through gravity. A baffle 45 is fixedly provided on the side wall of the installation frame 42, and a fourth spring 451 is fixedly provided on the lower surface of the baffle 45. The bottom end of the fourth spring 451 is fixedly connected to the side block 43, and the fourth spring 451 is a compression spring. The side wall of the side block 43 is rotatably connected with an arc clamp 432, and a lifting rod 4321 is mounted on the bottom of the arc clamp 432. The rotation axis of the arc clamp 432 is provided with a torsion spring that allows the bottom end of the arc clamp 432 to rotate toward the middle of the installation frame 42.

[0025] The first telescopic cylinder 5 is mounted above the second conveyor belt 6 and is located above the mounting frame 42. A top plate 51 is fixed to the circumferential outer wall of the piston rod of the first telescopic cylinder 5, and a third spring 52 is fixed to the lower surface of the top plate 51. A bottom plate 53 is fixed to the bottom end of the third spring 52, and the bottom plate 53 is slidably connected to the piston rod. The elastic force of the third spring 52 is greater than the pulling force of the first spring 411. The bottom plate 53 can abut against the top of the mounting frame 42, and the piston rod of the first telescopic cylinder 5 can extend into the mounting frame 42. The bottom plate 53 abuts against the top of the mounting frame 42 and can drive the mounting frame 42 to move to a position where the lifting rod 4321 is tightly against the side wall of the material frame 11, and the lifting rod 4321 is located below the lifting plate 121. The piston rod of the first telescopic cylinder 5 can abut with the extension plate 422 to the position where the disengagement rod 4221 abuts against the freeze-drying surface, and at this time, the side block 43 moves to the position where the lifting rod 4321 pulls out the partition frame 12.

[0026] The second conveyor belt 6 drives the material frame 11 to move to the bottom of the first telescopic cylinder 5 and then stops. The piston rod of the first telescopic cylinder 5 extends, and the bottom plate 53 abuts against the mounting frame 42 and drives the mounting frame 42 to move downward. When the mounting frame 42 moves to the bottom, the lifting rod 4321 abuts against the inclined surface of the lifting plate 121 and then abuts against the side wall of the material frame 11 and is located below the lifting plate 121. Then, the piston rod of the first telescopic cylinder 5 continues to move downward, and the third spring 52 is compressed at this time. The piston rod of the first telescopic cylinder 5 abuts against the extension plate 422 and drives the extension plate 422 to move downward. During the downward movement of the extension plate 422, the disengagement rod 4221 extends from the guide cylinder 4211, and drives the side block 43 to move upward through the traction rope 431. When the side block 43 moves upward, the lifting rod 4321 abuts against the lifting plate 121 and drives the partition frame 12 to move upward. At the same time, the disengagement rod 4221 abuts against the freeze-dried product to separate the freeze-dried product from the partition frame 12. The setting of the guide cylinder 4211 can provide space for the upward movement of the partition frame 12. Then, during the resetting process of the installation frame 42, the first spring 411 causes the partition frame 12 to move upward, thereby realizing the separation of the partition frame 12 from the material frame 11 and the freeze-dried food, and the partition frame 12 moves toward the third conveyor belt 7 as the turntable 4 rotates.

[0027] refer to Figure 3 and Figure 4, the placement assembly 8 includes a second telescopic cylinder 81, an extension plate 82 and an insertion plate 83. The second telescopic cylinder 81 is mounted above the third conveyor belt 7. The top plate 51, the bottom plate 53 and the third spring 52 are also mounted on the piston rod of the second telescopic cylinder 81, and the positional relationship after installation is the same as that on the first telescopic cylinder 5. The bottom plate 53 can drive the installation frame 42 to move down to a position where the partition frame 12 is placed on the third conveyor belt 7 and the lifting rod 4321 is located below the lifting plate 121. There are two extension plates 82, which are fixed on the piston rod of the second telescopic cylinder 81 and located above the top plate 51. The extension plate 82 extends to both sides of the installation frame 42 and then extends downward. An insertion groove 821 is provided at the bottom end of the downwardly extending portion of the extension plate 82, and a fifth spring 8211 is fixed on the top wall of the insertion groove 821. The insertion plate 83 is slidably connected in the insertion groove 821 and fixedly connected to the fifth spring 8211. The insertion plate 83 partially extends out of the insertion slot 821, and the side wall of the part of the insertion plate 83 extending out of the insertion slot 821 is provided with a hooking slot 831, and the bottom of the insertion plate 83 is inclined and transitionally arranged. An unlocking rod 4322 is fixedly arranged on the side wall of the arc clamp 432, and the piston rod of the second telescopic cylinder 81 can drive the insertion plate 83 to move to abut against the unlocking rod 4322 and make the unlocking rod 4322 located in the insertion slot 821, at which time the lifting rod 4321 is staggered from the lifting plate 121. After the installation frame 42 is reset, the force exerted on the lifting rod 4321 can be disengaged from the hooking slot 831. A separation plate 412 is mounted on the station frame 41, and the separation plate 412 is vertically arranged and has an inclined surface at the bottom. After the installation frame 42 is reset, the separation plate 412 abuts against the unlocking rod 4322 and disengages the unlocking rod 4322 from the hooking slot 831. If the lifting rod 4321 is located in the groove at the bottom of the lifting plate 121 , when the unlocking rod 4322 abuts against the separation plate 412 , the lifting rod 4321 will abut against the groove at the bottom of the lifting plate 121 , and the arc clamp 432 will not rotate and open.

[0028] The turntable 4 rotates to rotate the partition frame 12 to the bottom of the second telescopic cylinder 81 and then stops. The piston rod of the second telescopic cylinder 81 extends, so that the bottom plate 53 abuts against the installation frame 42 and drives the installation frame 42 to move down to the position where the partition frame 12 is placed on the third conveyor belt 7. Then the telescopic cylinder continues to move down, so that the extension plate 82 drives the insertion plate 83 to abut against the insertion rod and the arc clamp 432 rotates and opens. The lifting rod 4321 is located on one side of the lifting plate 121, and the unlocking rod 4322 is located in the hook groove 831, so that the partition frame 12 is completely placed on the third conveyor belt 7. Then the third conveyor belt 7 can move to take the partition frame 12 away. During the resetting process of the second telescopic cylinder 81, the extension plate 82 moves up first. Due to the abutment relationship between the unlocking rod 4322 and the hook groove 831, the length of the insertion plate 83 extending out of the insertion groove 821 increases, so that the arc clamp 432 remains in an open state. During the subsequent resetting process of the mounting frame 42 , the unlocking rod 4322 opens at a larger angle under the contact of the separation plate 412 , and then separates from the insertion plate 83 , and the insertion plate 83 is reset.

[0029] refer to Figure 5 and Figure 6 The installation station 3 includes a material unloading rack 31 and a third telescopic cylinder 32. The material unloading rack 31 is a vertical shaft structure formed by connecting multiple vertical rods. The material unloading rack 31 is erected above the first conveyor belt 1, and the vertical rods of the material unloading rack 31 abut against the lifting plate 121 of the partition frame 12 or the partition frame 12. The side wall of the material unloading rack 31 is equidistantly provided with multiple one-way grooves 311, and the top of the one-way groove 311 is rotatably connected with a card plate 312, and the card plate 312 can be completely located in the one-way groove 311 after rotation. The rotating shaft of the card plate 312 is provided with a torsion spring, so that the card plate 312 maintains a horizontal state, and the distance between the one-way grooves 311 is not less than the height of the partition frame 12, and multiple card plates 312 can lift the partition frame 12 together. The third telescopic cylinder 32 is erected above the material unloading rack 31, and the piston rod is arranged downward and can extend into the material unloading rack 31, and the piston rod can move the partition frame 12 in the material unloading rack 31 to a position abutting against the lower card plate 312. The third conveyor belt 7 moves the partition frame 12 to above the unloading rack 31 .

[0030] The third conveyor belt 7 delivers the partition frame 12 to the top of the unloading rack 31 and stacks it on the top of the partition frame 12 below. The piston rod of the third telescopic cylinder 32 extends to press the partition frame 12 downward, so that the partition frame 12 moves downward to a position abutting against the next card plate 312, thereby moving the partition frame 12 downward together by one unit, and pressing the lowest partition frame 12 down into the material frame 11.
