Description

Technical Field

[0001] The invention relates to the technical field of pre-prepared food processing, and in particular to a pre-prepared food preservation production device and method. Background Art

[0002] The fresh-keeping production device for pre-prepared dishes is a key equipment to ensure that the pre-prepared dishes can maintain their freshness and extend their shelf life during the production process. The fresh-keeping production device for pre-prepared dishes includes cleaning and sterilization equipment, processing and handling equipment, and packaging equipment. The cleaning and sterilization equipment includes bubble cleaning machines and ultraviolet sterilization equipment. Vegetable cleaning, as a key front-end process, is directly related to the quality and shelf life of the pre-prepared dishes. Bubble cleaning machines are widely used in the field of primary processing of vegetables because of their relatively high cleaning efficiency and relatively controllable costs.

[0003] The core operating mechanism of traditional bubble cleaning machines relies on an air pump to continuously blow gas into the cleaning tank, causing a large number of bubbles to rise in the water. At the same time, the circulating water pump drives the water to surge, and the bubbles and water flow work together to make the vegetables constantly roll and rub against each other in the cleaning tank. This method can indeed remove some loose dirt, dust and other impurities on the surface of the vegetables to a certain extent.

[0004] The main operating mechanism of the existing bubble cleaning machine is that the air pump blows air to produce a large number of bubbles, and cooperates with the circulating water pump to make the water flow circulate, so that the vegetables roll, collide and rub in the sink under the action of water flow and bubbles. However, this cleaning method is not effective, making it difficult to effectively remove tightly attached dirt with different properties. Pesticide residues on the surface of vegetables are difficult to be removed by the impact force of the bubble water flow due to chemical bonds. In addition, stubborn mud and dirt hidden in deep folds, root and stem junctions, etc. can also avoid the cleaning effect of water bubbles. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide a fresh-keeping production device and method for pre-prepared dishes, so as to solve the technical problem that the existing bubble cleaning machine uses an air pump to blow air and a circulating water pump to drive water to make vegetables tumble and rub in a water tank for cleaning, but has poor cleaning effect on tightly attached dirt with different properties, pesticide residues on the surface of vegetables and stubborn mud in hidden parts.

The discharging conveying module can be driven by a separate drive motor or connected to the conveying roller through a belt, and is ready to receive the cleaned vegetables at the end of the main body; S2: Cleaning process: Brushing and flushing coordination: When vegetables enter the bottom of the scrubbing mechanism, the multiple brushes of the scrubbing mechanism run in the reverse direction under the action of the transmission belt, scrubbing the vegetables in the reverse direction and reducing their running speed on the conveyor belt, thus increasing the cleaning time and improving the cleaning effect. At the same time, the multiple nozzle modules of the flushing mechanism spray pressurized water onto the vegetables to flush the sludge on their surface.

S4: Cleaning is completed: The cleaned vegetables are sent out by the discharging conveying module, completing the entire cleaning process.

[0013] To sum up, the present invention mainly has the following beneficial effects: the present invention washes vegetables in multiple directions through the reverse operation of the washing mechanism and the reciprocating washing, coordinated pressurized water flow of the flushing mechanism and the bubble action of the bubble generating mechanism, effectively removes various types of dirt and pesticide residues, significantly improves the cleaning effect, ensures the cleanliness of the pre-prepared food raw materials, and is conducive to preservation.

The flushing mechanism nozzle flushes at multiple angles and realizes water recycling through the reflux box and the filter plate, which not only saves water but also avoids secondary pollution of sludge, reduces costs and is environmentally friendly. The design of various components is exquisite. For example, the baffles and drainage holes of the conveying mechanism ensure stable conveying, and the guide rods and bearings of the washing mechanism ensure smooth and precise movement, which improves the reliability and life of the device as a whole, provides an efficient, environmentally friendly and reliable solution for the preservation production of pre-prepared food, and strongly promotes the high-quality development of the pre-prepared food industry.

[0016] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0017] The following describes an embodiment of the present invention based on its overall structure.

[0018] Embodiment 1 A device and method for pre-prepared food preservation production, such as Figure 1-14 As shown, it includes a main body 1, a conveying mechanism 2, a washing mechanism 3, a transmission mechanism 4, a flushing mechanism 5, a bubble generating mechanism 6, a bottom support frame 7 and a discharging conveying module 8; The main body 1 is the shell of the whole fresh-keeping production device, and contains other components inside, providing a space for operations such as washing and preserving pre-prepared dishes. The bottom support frame 7 is located at the bottom of the main body 1, and plays a role in supporting the main body 1 and the whole device, ensuring the stability of the device during operation, so that it can be stably placed on the ground or a workbench; The conveying mechanism 2 includes a conveying belt 201, two sets of conveying rollers 202 and a rotating shaft 203. The conveying belt 201 is wound around the outside of the two sets of conveying rollers 202 to form a circulating conveying channel. The two sets of conveying rollers 202 and the main body 1 are rotatably connected through the rotating shaft 203, so that the conveying rollers 202 can flexibly rotate on the main body 1. A transmission hole 204 is provided inside one of the rotating shafts 203 for connecting with the output end of an external driving motor to receive power. A drainage hole 205 is provided on the surface of the conveyor belt 201 to facilitate the discharge of waste water during the cleaning process. A plurality of baffles 206 are evenly arranged on the surface of the conveyor belt 201 to prevent the vegetables from slipping during the conveying process and ensure that the vegetables can move stably on the conveyor belt. Specifically, when the external driving motor is started, its output shaft drives one set of conveying rollers 202 to rotate through the connection with the transmission hole 204. Since the conveying belt 201 is wound around the two sets of conveying rollers 202, the rotation of the conveying rollers 202 will cause the conveying belt 201 to move accordingly, thereby realizing the transportation of vegetables. Vegetables enter the device from one end of the top of the conveying mechanism 2, and the conveyor belt 201 smoothly transports the vegetables to the bottom of the subsequent washing mechanism 3 for washing. The presence of the drainage hole 205 allows the water sprayed by the nozzle module 510 and the residual water on the vegetables to be discharged in time during the washing process, so as to avoid water accumulation on the conveyor belt and affect the conveying effect. The baffle 206 effectively constrains the position of the vegetables, ensuring that the vegetables will not fall during high-speed transportation, thereby improving the reliability of transportation. The scrubbing mechanism 3 includes a transmission roller 301, a cross transmission shaft 302, a transmission belt 304, a brush 305, a driving plate 306, a moving frame 309, a slider 310, a reciprocating screw rod 311, a driving rod 312, a guide rod 313, a bearing 303 and a slip ring 307. The two sets of transmission rollers 301 and the main body 1 are connected through the cross transmission shaft 302, and the transmission rollers 301 and the cross transmission shaft 302 are radially limited and axially slidably connected. Multiple groups of brushes 305 are evenly distributed and fixed on the outside of two groups of transmission belts 304. The transmission belts 304 are wound around the two sides of the outside of the two groups of transmission rollers 301. Two groups of driving plates 306 are located on the outside of the two groups of transmission belts 304. The moving frame 309 is fixed on the top of the two groups of driving plates 306. The slider 310 is fixed at the middle position of the top of the moving frame 309. The reciprocating screw rod 311 passes through the slider 310 and is connected to the main body 1 through the driving rod 312. The two sets of guide rods 313 pass through the moving frame 309 and are fixedly connected to the inner wall of the main body 1 on both sides. The guide rods 313 and the moving frame 309 are slidably connected. The cross transmission shaft 302 and the main body 1 are rotationally connected through the bearing 303. The driving plate 306 and the cross transmission shaft 302 are slidably connected through the slip ring 307. The slip ring 307 and the cross transmission shaft 302 are axially sliding and radially rotating. When the vegetables enter under the washing mechanism 3, the transmission mechanism 4 drives the cross transmission shaft 302 to rotate, thereby rotating the transmission roller 301, and the transmission roller 301 drives the transmission belt 304 to move, so that the brush 305 washes the vegetables. Due to the special transmission mode of the transmission mechanism 4, the brush 305 runs in the reverse direction under the action of the transmission belt 304, that is, in the opposite direction of the conveying direction of the vegetables. In this way, not only can the vegetables be washed in the reverse direction, but the reverse-running brush 305 can also reduce the running speed of the vegetables on the conveyor belt 201 to a certain extent, thereby increasing the contact time between the vegetables and the brush 305 and improving the washing effect. At the same time, the driving rod 312 drives the reciprocating screw rod 311 to rotate under the drive of the transmission mechanism 4, and the reciprocating screw rod 311 causes the slider 310 to reciprocate thereon, and the slider 310 drives the transmission roller 301, the transmission belt 304 and the brush 305 to reciprocate along the axial direction of the cross transmission shaft 302 through the moving frame 309 and the driving plate 306, so that the brush 305 can reciprocate and wash the vegetables while running in the reverse direction; This reciprocating scrubbing action can more comprehensively clean the surface of vegetables and effectively remove tightly attached dirt. The guide rod 313 plays a role in guiding and stabilizing the movable frame 309 in this process, ensuring that the reciprocating motion of the slider 310 and the brush 305 is carried out smoothly. The bearing 303 ensures the smooth rotation of the cross transmission shaft 302, and the slip ring 307 enables the driving plate 306 to stably slide axially and rotate radially on the cross transmission shaft 302, thereby ensuring the normal operation of the entire scrubbing mechanism 3. The transmission mechanism 4 includes a connecting gear 401, a steering gear 402, a transmission gear 403, a coaxial gear 404, a driving gear 406, a first synchronous belt 405 and a second synchronous belt 407. The connecting gear 401 is fixed to the outside of one set of rotating shafts 203, and the steering gear 402 is movably connected to one side of the main body 1 and meshes with the connecting gear 401. One set of transmission gears 403 and coaxial gears 404 are fixed on the outside of one set of cross transmission shafts 302, and transmission gears 403 are fixed on the outside of both sets of cross transmission shafts 302. A driving gear 406 is fixed on the outside of one set of driving rods 312. The steering gear 402 and the coaxial gear 404 are connected by a first synchronous belt 405, and the two sets of transmission gears 403 and the driving gear 406 are connected by a second synchronous belt 407. Specifically, when the external driving motor drives the conveying roller 202 to rotate, the connecting gear 401 fixed on the rotating shaft 203 rotates accordingly, and the connecting gear 401 meshes with the steering gear 402 to transmit power to the steering gear 402. The steering gear 402 drives the coaxial gear 404 to rotate through the first synchronous belt 405. Since the coaxial gear 404 and the transmission gear 403 are coaxially arranged, the transmission gear 403 also starts to rotate; The transmission gears 403 on the outside of the two sets of cross transmission shafts 302 drive the driving gears 406 to rotate through the second synchronous belt 407, and then the driving rod 312 rotates, and finally the brush 305 of the scrubbing mechanism 3 is reversely operated and reciprocated. The transmission mechanism 4 cleverly distributes and transforms the power of the conveying mechanism 2 through the cooperation of a series of gears and synchronous belts, realizes multiple movement modes of the scrubbing mechanism 3, ensures the coordinated work of the entire device, and improves the cleaning efficiency. The flushing mechanism 5 includes a water spray main pipe 508, a water spray branch pipe 509, a nozzle module 510, a reflux box 501, a water storage chamber 502, a water suction pipe 505, a water pump module 506, a water outlet pipe 507, a support plate 503 and a filter plate 504. The water spray main pipe 508 is fixed to one side of the main body 1, and multiple groups of water spray branch pipes 509 extend through the inside of the washing mechanism 3 in the main body 1. The multiple groups of water spray branch pipes 509 are connected to the water spray main pipe 508, and multiple groups of nozzle modules 510 are inclinedly arranged at one end of each group of water spray branch pipes 509. The reflux box 501 is located at one end of the main body 1, and the water storage chamber 502 provided in the reflux box 501 is connected to the inside of the main body 1. The water pump module 506 is installed at the bottom of one end of the main body 1, and the water inlet end of the water pump module 506 is connected to the reflux box 501 through the water suction pipe 505, and the water outlet end of the water pump module 506 is connected to the water spray main pipe 508 through the water outlet pipe 507. The support plate 503 is located inside the reflux box 501 and is slidably connected thereto. Multiple groups of inclined filter plates 504 are evenly fixed at one end of the support plate 503. A cover plate is provided on the top of the reflux box 501, and the cover plate and the reflux box 501 are movably connected;

[0019] Specifically, when the water pump module 506 is working, it extracts filtered water from the water storage chamber 502 of the return box 501 through the water suction pipe 505, and then transports the water to the water spray main pipe 508 through the water outlet pipe 507. The water is divided into various water spray branch pipes 509 in the water spray main pipe 508, and finally sprayed out from the nozzle module 510. The nozzle module 510 is tilted and can spray the pressurized water flow at a certain angle to the vegetables to wash the sludge on the surface of the vegetables. Since the angle of the nozzle module 510 is toward the feeding end of the conveying mechanism 2, the water in the main body 1 flows toward the return box 501 under the action of the flushing water flow, and the washed sludge enters the return box 501 with the water flow; The multiple groups of filter plates 504 in the reflux box 501 filter the sludge to prevent the sludge from entering the circulating water system again. The filtered water enters the water storage chamber 502, realizing the recycling of water resources and saving water resources. When the filter plates 504 need to be cleaned, the cover plate on the top of the reflux box 501 is opened, and the support plate 503 and the filter plate 504 are taken out as a whole through the groove on the top of the support plate 503 for cleaning, thereby improving the filtering efficiency and ensuring the long-term stable operation of the flushing mechanism 5. The bubble generating mechanism 6 comprises an air pump module 601, an air jet main pipe 602, an air jet branch pipe 603 and a sealing ring 604. The air jet main pipe 602 is connected to the air outlet end of the air pump module 601. A plurality of air jet branch pipes 603 extending to the bottom of the main body 1 are evenly fixed on the inner side of the air jet main pipe 602. A sealing ring 604 is arranged between each air jet branch pipe 603 and the main body 1. When the air pump module 601 is working, it sucks in external gas and transports it to the jet branch pipe 603 through the jet main pipe 602. The jet branch pipe 603 injects the gas into the water at the bottom of the main body 1 to form bubbles. The function of the sealing ring 604 is to prevent gas leakage and ensure that bubbles can be effectively generated in the water. During the rising process of the bubbles in the water, the vegetables roll and rub against each other in the cleaning tank, further improving the cleaning effect, and can help remove some difficult-to-clean dirt on the surface of the vegetables, such as stubborn mud in hidden parts such as deep folds and root-stem junctions. It also helps to remove pesticide residues on the surface of the vegetables and improve the preservation effect of pre-prepared vegetables. The discharging conveying module 8 is fixedly connected to one end of the main body 1 and is arranged at an angle. Its function is to convey the cleaned vegetables out of the main body 1 to facilitate subsequent processing or packaging. The discharging conveying module 8 can be driven by a separate drive motor or by a belt connection with the conveying roller 202 to ensure that the vegetables can be smoothly output from the device and complete the cleaning process of the entire pre-prepared food preservation production.

[0020] The working principle of the present invention is as follows: when in use, the power supply is turned on, and the external power supply device supplies power to the water pump module 506 and the air pump module 601 through the wire, so that the water pump module 506 can ensure the circulation of water flow, and the air pump module 601 can absorb external gas and inject it into the water body inside the main body 1 to form bubbles; At the same time, the output shaft of the external driving motor and the transmission hole 204 are engaged with each other, so that the external driving motor can drive one set of conveying rollers 202 to rotate. Since the two sets of conveying rollers 202 are connected to each other through the conveyor belt 201, the external driving motor can drive the conveyor belt 201 to convey the vegetables. A discharge conveying module 8 is provided at the end of the main body 1, wherein the discharge conveying module 8 can be driven by a separate driving motor, or can be driven by being connected to the conveying roller 202 through a belt; When vegetables need to be washed, such as potatoes, radishes and other vegetables, the staff dumps the vegetables to one end of the top of the conveying mechanism 2. At this time, the vegetables enter the bottom of the washing mechanism 3 under the action of the conveyor belt 201, wherein the multiple groups of brushes 305 of the washing mechanism 3 can perform reciprocating washing actions on the vegetables, and cooperate with the multiple groups of nozzle modules 510 of the flushing mechanism 5 to pressurize the water flow to a certain degree to perform a flushing operation on the vegetables simultaneously. As can be seen from the above, the overall vegetable washing process is good; Specifically, the connecting gear 401 is meshed with the steering gear 402, and the steering gear 402 is connected with the coaxial gear 404 via a first synchronous belt 405. Since the coaxial gear 404 and the transmission gear 403 are coaxially arranged, they are both arranged on the outside of one set of cross transmission shafts 302, and the transmission gear 403 and the driving gear 406 arranged on one side of the two sets of cross transmission shafts 302 are connected via a second synchronous belt 407. As can be seen from the above, when the conveyor belt 201 is conveying the vegetables in the forward direction, the multiple groups of brushes 305 of the scrubbing mechanism 3 are running in the reverse direction under the action of the transmission belt 304. That is to say, the brushes 305 running in the reverse direction can not only perform a reverse scrubbing operation on the vegetables, but also reduce the running speed of the vegetables on the conveyor belt 201 to a certain extent, thereby improving the scrubbing effect of the vegetables. Furthermore, since the driving gear 406 and the transmission gear 403 are connected by the second synchronous belt 407, the driving gear 406 synchronously drives one set of driving rods 312 to rotate, and the driving rods 312 drive the reciprocating screw rod 311 to rotate, and the reciprocating screw rod 311 drives the slider 310 to reciprocate. That is to say, the reciprocating movement of the slider 310 drives the two sets of transmission rollers 301, the transmission belts 304 and the multiple sets of brushes 305 to move axially back and forth along the two sets of cross transmission shafts 302 through the two sets of moving frames 309 and the two sets of driving plates 306, so that the multiple sets of brushes 305 can perform reciprocating washing action on the vegetables while running in the reverse direction, thereby further improving the washing effect of the vegetables; During the vegetable washing process, the bubble generating mechanism 6 injects gas into the water inside the main body 1 through the air pump module 601, the jet main pipe 602, and the jet branch pipe 603 to form bubbles, wherein the bubbles make the vegetables continuously roll and rub against each other in the washing tank, further improving the washing effect of the vegetables and ensuring the freshness preservation effect of the subsequent pre-prepared dishes; At the same time, the multiple groups of nozzle modules 510 of the flushing mechanism 5 synchronously flush the vegetables, so that the sludge on the surface of the vegetables can be effectively separated. In detail, since the angles of the multiple groups of nozzle modules 510 are toward the feeding end of the conveying mechanism 2, the water inside the main body 1 gradually flows toward the return box 501 at one end of the main body 1 under the action of the flushing water flow of the nozzle modules 510. At this time, since the water contains continuously generated bubbles, the washed sludge can flow to the inside of the return box 501 along with the flow of water. At this time, the multiple groups of filter plates 504 inside the reflux box 501 can filter the sludge, and the filtered water enters the water storage chamber 502. Under the suction action of the water pump module 506, the filtered water in the water storage chamber 502 is passed through the water outlet pipe 507 and the water spray main pipe 508 to enter the multiple groups of water spray branch pipes 509 through the water suction pipe 505, and then can be sprayed to the surface of the vegetables on the conveyor belt 201 through the multiple groups of nozzle modules 510 again, so as to perform a circulating flow washing operation; Since the multiple groups of nozzle modules 510 are located inside between the multiple groups of brushes 305, when the multiple groups of brushes 305 are running in the reverse direction with the transmission belt 304, the multiple groups of nozzle modules 510 can spray a part of the water flow onto the brushes 305, so that the sludge clamped inside the brushes 305 can be quickly washed away, thereby improving the washing process of the brushes 305 on the vegetables; Furthermore, since the diameter of the connecting gear 401 is larger than the steering gear 402 and the coaxial gear 404, that is, the forward running speed of the conveyor belt 201 is lower than the reverse running speed of the multiple sets of brushes 305, and thus during the slow forward running of the vegetables, the multiple sets of brushes 305 increase the frequency of washing the vegetables, further improving the washing effect of the vegetables; Similarly, since the diameter of the transmission gear 403 is larger than the diameter of the driving gear 406, the reciprocating scrubbing action frequency of the multiple groups of brushes 305 is accelerated, and the rapid scrubbing action can effectively and thoroughly remove the sludge adhering to the surface of the vegetables; As can be seen from the above, the present invention firstly realizes that the water pump module 506 ensures water circulation through external power supply, the air pump module 601 injects gas to form bubbles, and cooperates with the external driving motor to drive the conveyor belt 201 to transport vegetables, thereby ensuring stable operation of the equipment; Secondly, the brush 305 of the scrubbing mechanism 3 is used to run in reverse, reciprocate, and work in conjunction with the nozzle module 510 of the flushing mechanism 5 to effectively remove the sludge on the surface of the vegetables, and at the same time, the bubbles can make the vegetables roll and rub in the cleaning tank, further improving the cleaning effect; Fourth, a reflux tank 501 and related water circulation components are provided to realize water filtration and recycling, thus saving water resources; Fifth, by making use of the reasonable size differences between the relevant components, the frequency and frequency of the brushing action of the vegetables are increased, and the sludge stuck on the surface of the vegetables is more thoroughly removed, which greatly improves the overall vegetable cleaning effect and ensures the preservation effect of subsequent pre-prepared dishes.
