Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of food packaging equipment, in particular to a vacuumizing device for instant food production and processing. BACKGROUND

[0002] As an important category of convenient consumption scenarios, the core advantage of instant food lies in that it can be directly consumed without additional processing or only simple processing. Braised food is a typical representative of instant food. This type of food takes braised meat and bean products as the main carrier and relies on liquid braising sauce to achieve flavor presentation and taste improvement. However, the large amount of liquid braising sauce contained in it also makes it have higher requirements for storage and transportation conditions. In order to extend the shelf life of the product and avoid external microbial contamination, vacuum packaging technology has become a key link in the production and processing of braised instant food. By removing air from the packaging, anoxic environment can be created, which can effectively inhibit microbial reproduction and reduce the oxidation of braising sauce ingredients, thereby ensuring the quality stability of the product in the circulation link.

[0003] However, when using conventional vacuum packaging technology for braised instant food, there are two core technical problems. On the one hand, the low-pressure environment formed during the conventional vacuumizing process can change the physical state of the braising sauce liquid and cause the braising sauce to boil, producing a large amount of liquid spray. If these sprays are sucked into the vacuum pump during the air extraction process, they will adhere to the surface of the core components of the pump body to form oil stains, and long-term accumulation can also cause blockage of the pump body pipeline, affecting the normal operating efficiency of the vacuum pump, and even causing equipment failure and downtime, increasing production and maintenance costs.

[0004] On the other hand, the liquid components in braised food are easily adsorbed to the sealing area of the packaging bag during the vacuumizing process due to the flow of air and pressure changes inside the packaging. These residual liquid components can form an oil film on the sealing surface, which can destroy the tight bonding state of the heat-sealing layer of the packaging, resulting in failure of the heat-sealing effect. Even after completing the packaging process, the sealing area is prone to air leakage during subsequent storage or transportation, allowing external air and microorganisms to enter the packaging, ultimately causing product deterioration. Therefore, the present application provides a vacuumizing device for instant food production and processing to solve the above technical problems. SUMMARY

[0014] Working principle: in the vacuum packaging of the instant food of the marinade, first guide processing mechanism start, the staff first marinade instant food filled with packaging bag from the installation cover on the import into the installation cover inside the work station one, then into the installation cover inside the packaging bag is inserted into the guide seat on the base, and in the process of packaging bag into the guide seat guide groove, the instant food in the packaging bag in the process of falling through both sides of the flexible arc guide strip will be guided to move to the middle of the packaging bag, in the process of packaging bag into the guide seat guide groove, dispersed in the air and liquid in the packaging bag in the process of entering into the guide groove, through the internal friction of each group of guide extrusion roller rotation, so that the air at the edge of the packaging bag extrusion discharge, the liquid at the edge of the packaging bag is accumulated in the middle of the packaging bag, at the same time, affected by the guide inside the inclined surface, after the packaging bag completely into the guide seat, the instant food in the packaging bag is moved to the middle of the packaging bag, so as to improve the stability of the subsequent packaging form and guarantee the uniformity of the vacuum degree, so as to complete the position guide processing of the instant food before vacuum packaging.Then the front end pre-cooling mechanism starts, after the guide processing mechanism finishes processing the packaging bag containing instant food, the step turntable in the installation cover starts, the step turntable transfers the instant food processed by the guide processing mechanism in station one to the position of station two at the same time of starting, and in the process of transferring, the packaging bag containing instant food in the guide seat rubs the flexible rotating septum on the installation rod to rotate synchronously, after the packaging bag containing instant food in the guide seat moves to the position of station two, the flexible rotating septum on both sides of the guide seat rotates and cooperates with the vertical seat on both sides to separate the two sides of the packaging bag from other space in the installation cover, then the liquid nitrogen generator on the processing box starts, the liquid nitrogen generator injects the generated liquid nitrogen into the liquid nitrogen cavity in the processing box, the cold content contained in the liquid nitrogen in the liquid nitrogen cavity is conducted through the gas flow cavity on the partition plate, at this time the axial flow fan on the processing box starts, the axial flow fan injects gas into the gas flow cavity in the processing box, the gas in the gas flow cavity exchanges heat with the heat conducted by the metal conducting sheet in the process of flowing, so that the gas in the gas flow cavity is cooled to form cold gas, then the cold gas after cooling treatment enters into each gas flow channel in the vertical seat after being dispersed by the dispersion groove in the vertical seat, then the cold gas in the gas flow channel is discharged onto the packaging bag containing instant food through the conical discharge hole on the vertical seat, the instant food in the packaging bag is pre-cooled and cooled, and the marinade contained in the instant food is also changed from liquid to solid, so as to prevent liquid overflow during subsequent vacuum packaging, and when the cold gas in the gas flow channel is discharged through the conical discharge hole, the pressure of the cold gas is increased due to the compression of the hole diameter, so that the impact force of the cold gas reaching the surface of the packaging bag is stronger, which is convenient for subsequent vacuum packaging, so as to complete the front end pre-cooling processing of the instant food before vacuumizing.After the food packaging mechanism starts, the step turntable in the installation cover is started after the front-end pre-cooling mechanism finishes the freezing treatment of the instant food, and the step turntable simultaneously transfers the instant food on the work station 2 after the front-end pre-cooling mechanism to the position of the work station 3, and simultaneously seals the two sides of the instant food through the silica gel sealing strips on both sides of the installation seat, so that the packaging bag containing the instant food is in a relatively sealed space in the installation seat. When the instant food in the guide seat enters the inside of the installation seat, the air pump on the installation cover is started, and the air pump simultaneously injects high-pressure gas into the inner cavity of the installation seat. With the increasing content of high-pressure gas in the inner cavity of the installation seat, the high-pressure gas in the inner cavity extrudes the silica gel diaphragm on the installation seat to deform outward. The silica gel diaphragm extrudes the packaging bag containing the instant food in the process of deformation, so as to exhaust the residual gas in the packaging bag. Since the installation seat forms a relatively sealed space with the cooperation of the silica gel sealing strips, the gas exhausted into the sealed space also acts on the surface of the packaging bag, assisting the exhaust of the residual gas in the packaging bag. Thus, the gas in the packaging bag is completely exhausted, that is, the inside of the packaging bag is vacuumized, so as to complete the vacuum packaging treatment of the instant food. After the food packaging mechanism finishes the vacuum processing of the instant food in the packaging bag, the gas in the inner cavity enters the gas heater for heating. The high-temperature gas heated by the gas heater is exhausted at the upper part of the packaging bag through the guidance of the inclined guide plate. The guidance of the inclined guide plate not only avoids the heating and melting of the instant food in the packaging bag by the high-temperature gas, but also improves the heat sealing effect of the sealing part during subsequent packaging and preheats the heat-sealed position of the packaging bag. Then, the displacement adjuster on the installation seat is started, and simultaneously controls the heat-sealing seat in the installation seat to move to the middle part, so as to heat-seal the heat-sealed position of the packaging bag after preheating, and heat-seal the packaging bag. At this time, the instant food after packaging is transferred to the position of the work station 4 through the transfer of the step turntable in the installation cover, and the packaged instant food can be taken out from the taking-out port of the installation cover. The above operation is repeated to complete the continuous packaging of the instant food, so as to complete the heat-sealing treatment of the packaging bag of the instant packaging product.

[0015] The application provides an instant food production and processing vacuumizing device. 1. The application increases and sets the guide processing mechanism. Before the vacuumizing processing of the packaging bag containing instant food, the mechanism can guide the instant food and the marinade in the packaging bag to the middle part through the cooperation of the flexible arc-shaped guide strip and the inclined surface of the guide seat, avoids the instant food close to the edge of the bag opening, and reduces the probability of liquid components adhering to the sealing area during vacuumizing. Secondly, the guide extrusion roller can extrude and discharge the air at the bag edge and gather the liquid, so that the sealing area remains relatively dry, providing a clean basis for subsequent heat sealing, and allowing the food to be more regular in the bag, avoiding packaging deformation caused by uneven local stress, and ensuring the stability of the vacuumizing process.

[0016] 2. The application increases and sets the front end pre-cooling mechanism. Before the vacuumizing processing of the packaging bag containing instant food, the mechanism not only pre-cools the marinade food through the cold gas generated by liquid nitrogen, which can convert liquid marinade into solid, preventing liquid boiling and generating flying spray during vacuumizing, but also forms an isolation space through the cooperation of the flexible rotating baffle and the vertical seat, which can reduce the interference of external temperature on the pre-cooling effect and make the cooling more uniform. In addition, the conical exhaust hole enhances the impact force of the cold gas, which not only improves the pre-cooling efficiency, but also further inhibits the flowability of the marinade during subsequent vacuumizing, reducing the risk of overflow.

[0017] 3. The application increases and sets the food packaging mechanism. When the packaging bag containing instant food is vacuumized, on the one hand, the silica gel sealing strip in the mechanism makes the packaging bag in a relatively sealed space, and cooperates with the flexible extrusion of the silica gel diaphragm driven by the air pump, which can efficiently discharge the residual gas in the bag, ensuring the completeness of the vacuumizing effect. On the other hand, the deformation extrusion of the silica gel diaphragm can adapt to food packaging of different shapes, avoiding damage to the food shape caused by rigid extrusion, and the gas pressure in the sealed space can assist in discharging the dead corner air in the bag, reducing the situation of insufficient vacuum degree, and improving the food preservation effect.

[0018] 4. The application increases and sets the sealing processing mechanism. After the vacuumizing processing of the packaging bag containing instant food, since the high-temperature gas is guided by the inclined guide plate, the mechanism can accurately preheat the sealing area of the packaging bag without directly contacting the food, which not only avoids the melting and overflow of the marinade caused by high temperature, but also improves the tightness of the heat sealing layer. Therefore, the accurate sealing of the heat sealing seat under the control of the displacement regulator can effectively prevent the air leakage problem caused by loose sealing, and the design can adapt to the sealing needs of packaging bags of different specifications, enhancing the versatility of the equipment and ensuring the stability of the product during subsequent storage and transportation.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the specification of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0022] Please refer to the drawings in the specification of the present application Figure 1 - the drawings in the specification of the present application Figure 2 The embodiment of the present application provides a vacuumizing device for instant food production and processing, which comprises a base 1, a mounting cover 9 is arranged at the top middle part of the base 1, four station identification seats 2 are arranged in the outer wall middle part of the mounting cover 9 in a circumferential array, the space in the mounting cover 9 is divided into four processing stations by the four station identification seats 2, and the four processing stations are station one, station two, station three and station four in sequence; a stepping turntable 10 is arranged at the inner side bottom of the mounting cover 9, four bases 19 are arranged in a circumferential array at the top of the stepping turntable 10, and the stepping turntable 10 drives the mechanisms on the four bases 19 to rotate between different processing stations in the stepping rotation process. Please refer to the drawings in the specification of the present application Figure 3The guiding and processing mechanism is set up on station one and is used to guide and process ready-to-eat foods in packaging bags before vacuum processing. The guiding and processing mechanism includes a feeding inlet 3. The top center of the mounting cover 9 is provided with a feeding inlet 3 for ready-to-eat food and packaging bags to enter. Multiple flexible arc-shaped guide strips 11 are equidistantly arranged on the top of the mounting cover 9 at workstation 1, and the flexible arc-shaped guide strips 11 on both sides are inclined.

[0023] When the guiding and processing mechanism is started, the staff first puts the packaging bag containing the braised ready-to-eat food into the work station 1 inside the mounting cover 9 through the feeding port 3 on the mounting cover 9. Then, the staff inserts the packaging bag into the guide seat 18 on the base 19. As the packaging bag enters the guide groove 12 on the guide seat 18, the ready-to-eat food in the packaging bag is guided to the middle position of the packaging bag by the flexible arc-shaped guide strips 11 on both sides during the descent.

[0024] The guiding and processing mechanism also includes a guide seat 18. The top center of the base 19 is fixedly connected to the guide seat 18, and the bottom inner side of the guide seat 18 is set with an incline. The inner center of the guide seat 18 is provided with a guide groove 12. Multiple sets of guide squeezing rollers 20 are equidistantly rotatably connected to the inner side of the guide groove 12. After the ready-to-eat food and its packaging bag enter the guide groove 12, the gas and liquid at the edge of the packaging bag are squeezed and gathered to the center by the multiple sets of guide squeezing rollers 20. At the same time, the ready-to-eat food in the packaging bag is also guided to the center position of the bag by the incline in the guide seat 18.

[0025] During the process of the packaging bag entering the guide groove 12 on the guide seat 18, the air and liquid dispersed around the packaging bag are squeezed out by the frictional rotation of each set of guide squeezing rollers 20 inside the guide groove 12. The liquid at the edge of the packaging bag is then accumulated in the middle of the packaging bag. At the same time, under the guidance of the inclined surface inside the guide seat 18, after the packaging bag is completely entered into the guide seat 18, the ready-to-eat food inside the packaging bag moves to the middle of the packaging bag, thereby improving the stability of the subsequent packaging form and ensuring the uniformity of the vacuum degree. This completes the position guidance process of the ready-to-eat food before vacuum packaging.

[0026] Please see the appendix Figure 4 - Appendix Figure 6 The front-end pre-cooling mechanism is located above station two and is used to guide the ready-to-eat food processed by the processing mechanism to undergo pre-cooling treatment before vacuuming. The front end pre-cooling mechanism comprises mounting rods 27, a plurality of mounting rods 27 are fixedly connected equidistantly on the top wall of the second station mounting cover 9, and a plurality of flexible rotating partitions 15 are arranged in a circular array on the mounting rods 27. After the flexible rotating partitions 15 are rubbed and rotated by the instant food and the packaging bag in the guide seat 18, the two sides of the guide seat 18 and the instant food and the packaging bag in the guide seat 18 are separated and isolated from the outside space.

[0027] When the front end pre-cooling mechanism is started, after the guide processing mechanism processes the packaging bag containing the instant food, the step turntable 10 in the mounting cover 9 is started. At the same time, the step turntable 10 transfers the instant food processed by the guide processing mechanism on the first station to the position of the second station. In the process of transferring, the flexible rotating partitions 15 on the mounting rods 27 are synchronously rotated by the packaging bag containing the instant food in the guide seat 18. After the packaging bag containing the instant food in the guide seat 18 moves to the position of the second station, the flexible rotating partitions 15 on both sides of the guide seat 18 are cooperated with the vertical seats 13 on both sides to separate the two sides of the packaging bag from other spaces in the mounting cover 9.

[0028] The front end pre-cooling mechanism further comprises a processing box 8, the processing box 8 is arranged on one side of the middle part of the mounting cover 9, a partition plate 22 is fixedly connected to the inside middle part of the processing box 8, the inside of the processing box 8 is sequentially separated into a liquid nitrogen cavity 21 and a gas flow cavity 24 from top to bottom by the partition plate 22, a plurality of metal conducting sheets 23 are equidistantly arranged on the partition plate 22, and the bottom ends of the metal conducting sheets 23 extend into the gas flow cavity 24, a liquid nitrogen generator 7 is arranged at the middle part of the top end of the processing box 8, the discharge end of the liquid nitrogen generator 7 is in communication with the inside of the liquid nitrogen cavity 21, and an axial flow fan 6 is arranged at the middle part of one side of the processing box 8, and the discharge end of the axial flow fan 6 is in communication with the inside of the inner cavity 32.

[0029] Then the liquid nitrogen generator 7 on the processing box 8 is started, the liquid nitrogen generated by the liquid nitrogen generator 7 is injected into the liquid nitrogen cavity 21 in the processing box 8, and the cold energy contained in the liquid nitrogen in the liquid nitrogen cavity 21 is conducted through the gas flow cavity 24 on the partition plate 22. At this time, the axial flow fan 6 on the processing box 8 is started, the axial flow fan 6 injects gas into the gas flow cavity 24 in the processing box 8, and the gas entering the gas flow cavity 24 exchanges heat with the heat conducted by the metal conducting sheets 23 in the process of flowing, so that the gas in the gas flow cavity 24 is cooled to form cold gas.

[0030] The front-end precooling mechanism also includes a vertical seat 13. A vertical seat 13 is provided in the middle of both sides of the bottom of the processing box 8. A dispersion groove 14 is provided on the top of the inner side of the vertical seat 13. Multiple gas flow channels 25 are provided at equal intervals in the middle of the bottom of the dispersion groove 14. Multiple sets of conical holes 26 are provided at equal intervals on the surface of the adjacent side of the vertical seat 13.

[0031] After cooling, the cold air is dispersed by the dispersion groove 14 inside the vertical seat 13 and then enters the various gas channels 25 therein. The cold air entering the gas channels 25 is then discharged through the conical outlet holes 26 on the vertical seat 13 onto the packaging bag containing the ready-to-eat food, pre-cooling the ready-to-eat food in the packaging bag. At the same time, the brine contained in the ready-to-eat food is changed from liquid to solid, thereby preventing liquid leakage during subsequent vacuum packaging. When the cold air in the gas channels 25 is discharged through the conical outlet holes 26, the pressure of the cold air increases due to the compression of the hole diameter, thereby making the impact force of the cold air reaching the surface of the packaging bag stronger, which facilitates the subsequent vacuum packaging. This completes the pre-cooling processing of the ready-to-eat food before vacuuming.

[0032] Please see the appendix Figure 7 The food packaging mechanism, located above station three, is used to vacuum process ready-to-eat foods that have been processed by the front-end pre-cooling mechanism. The food packaging mechanism includes a mounting base 16. The mounting base 16 is fixedly connected to the top of the inner wall of the mounting cover 9 at workstation 3. The mounting base 16 has an inner cavity 32 for high-pressure gas flow. Silicone membranes 33 are provided on the lower middle part of the inner side of the mounting base 16. Silicone sealing strips 31 are provided on both sides of the inner side of the mounting base 16. An air pump 5 is provided on one side of the top middle part of the mounting cover 9, and the discharge end of the air pump 5 is connected to the inside of the inner cavity 32.

[0033] When the food packaging mechanism is started, after the front-end pre-cooling mechanism has finished freezing the ready-to-eat food, the stepping turntable 10 inside the mounting cover 9 is started. At the same time, the stepping turntable 10 transfers the ready-to-eat food that was originally processed by the front-end pre-cooling mechanism at station two to station three. Simultaneously, the silicone sealing strips 31 on both sides of the mounting base 16 seal the two sides of the ready-to-eat food, so that the packaging bag containing the ready-to-eat food is in a relatively sealed space inside the mounting base 16.

[0034] When the instant food in the guiding seat 18 enters the inside of the mounting seat 16, the air pump 5 on the mounting cover 9 is started, and the air pump 5 injects high-pressure gas into the inner cavity 32 in the mounting seat 16 at the same time of starting. With the increasing content of high-pressure gas in the inner cavity 32 in the mounting seat 16, the high-pressure gas in the inner cavity 32 extrudes the silica gel diaphragm 33 on the mounting seat 16 to generate outward deformation. The silica gel diaphragm 33 extrudes the packaging bag containing the instant food in the process of deformation, so as to discharge the residual gas in the packaging bag. Since the mounting seat 16 forms a relatively sealed space under the cooperation of the silica gel sealing strip 31, the gas discharged into the sealed space also acts on the surface of the packaging bag at the same time, which assists the discharge of the residual gas in the packaging bag. Therefore, the gas in the packaging bag is completely discharged, that is, the inside of the packaging bag is vacuumized, so as to complete the vacuum packaging treatment of the instant food.

[0035] Please refer to the accompanying drawings Figure 8 The sealing treatment mechanism is arranged above the third station and is used for sealing the opening of the packaging bag of the instant food after the food packaging mechanism is treated.

[0036] The sealing treatment mechanism comprises the gas heater 29, the inner side of the mounting seat 16 is provided with the gas heater 29 at the upper middle part, the gas inlet of the gas heater 29 is communicated with the inside of the inner cavity 32, the inner side of the mounting seat 16 is fixedly connected with the inclined guide plate 30 at the middle part, the both sides of the mounting seat 16 are provided with the displacement adjuster 17 at the upper middle part, the inner side of the mounting seat 16 is provided with the heat sealing seat 28 at the upper middle part close to the edge, and the top side of the mounting cover 9 is provided with the taking-out opening 4.

[0037] When the sealing treatment mechanism is started, after the food packaging mechanism is treated, the gas in the inner cavity 32 enters the gas heater 29 to be heated, and then the high-temperature gas after being heated by the gas heater 29 is discharged at the upper part of the packaging bag through the guidance of the inclined guide plate 30. The guidance of the inclined guide plate 30 can not only avoid the heating and melting of the instant food in the packaging bag by the high-temperature gas, but also can preheat and warm the position of the heat sealing of the packaging bag.

[0038] Then the displacement adjuster 17 on the mounting seat 16 is started, and the displacement adjuster 17 controls the synchronous movement of the heat sealing seat 28 in the mounting seat 16 to the middle at the same time, so as to heat seal the heat sealing position after the preheating treatment of the packaging bag, and heat seal the packaging bag. At this time, the instant food after the packaging processing is transferred to the position of the fourth station through the transfer of the stepping turntable 10 in the mounting cover 9, and the staff can take out the instant food after the packaging processing from the taking-out port 4 on the mounting cover 9. The above operation is cycled, and the continuous packaging processing of the instant food is completed, so as to complete the heat sealing treatment of the packaging bag of the instant packaging product.

[0039] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
