Description

Technical Field

[0001] This application relates to the technical field of quick-frozen food processing, and in particular to an automated spraying device for quick-frozen dumplings before freezing. Background Technology

[0002] In the production of quick-frozen dumplings, the pre-freezing spraying process is crucial. This process involves spraying water mist or antifreeze onto the surface of the shaped dumplings to form a uniform liquid film or pre-crystallized layer before freezing. This helps improve the integrity and gloss of the dumplings' appearance during quick-freezing, reduces surface cracking and whitening caused by direct sublimation of moisture, and thus ensures product quality.

[0003] Currently, to improve production efficiency, dumplings are typically processed using automated spraying systems. However, directly spraying dumplings during transport increases the humidity in the production workshop, thereby disrupting the optimal conditions for dumpling production.

[0004] Therefore, a new spraying device is urgently needed. Utility Model Content

[0005] To address the problem that existing spraying devices disrupt the optimal conditions in dumpling production workshops, this application provides an automated spraying device for quick-frozen dumplings before freezing.

[0006] The automated pre-freezing spraying device for quick-frozen dumplings provided in this application adopts the following technical solution: An automated spraying device for quick-frozen dumplings before freezing includes: The spray room has a spray channel; A conveyor belt, located within the spray channel, is used to transport dumplings; A spray assembly includes a water mist nozzle located within the spray channel and above the conveyor belt, the water mist nozzle being used to spray water mist onto dumplings on the conveyor belt; The dehumidification assembly includes a sponge block, a containment chamber, a fog-blocking curtain, and a dehumidification pipe. The containment chamber is located at the bottom of the spray channel and below the conveyor belt. The sponge block is fixed to the inner wall of the spray channel and its top end contacts the lower part of the conveyor belt. The bottom end of the sponge block is located above the containment chamber. The fog-blocking curtain is disposed at both ends of the spray channel and is used to prevent water mist in the spray channel from escaping to the outside. The dehumidification pipe is disposed on the end faces of both ends of the spray channel and is used to absorb water mist passing through the fog-blocking curtain.

[0007] By adopting the above technical solution, by installing fog curtains and dehumidification pipes at both ends of the spray channel to block the escape of water mist, and by setting up sponge blocks and containment chambers in the spray channel, the escaped water mist can be actively adsorbed and collected. Thus, without affecting the dumpling spraying operation, most of the water mist generated by the spraying is effectively isolated and recovered, significantly reducing the increase in humidity in the production workshop, thereby maintaining the optimal temperature and humidity environment required for dumpling production, and solving the problem of traditional spraying devices damaging workshop production conditions due to water mist.

[0008] Optionally, the fog-blocking curtain and the dehumidification pipe are arranged in a one-to-one correspondence. The dehumidification pipe is located above the fog-blocking curtain and has an air intake hole with the opening of the air intake hole facing downward.

[0009] By adopting the above technical solution, and by placing the dehumidification pipe above the fog curtain with the air intake facing downwards, the rising water mist passing through the fog curtain can be more effectively removed, reducing the impact of water mist on the outside of the spray room.

[0010] Optionally, the dehumidification assembly further includes a negative pressure pump and a negative pressure pipe, wherein the negative pressure pump is located outside the spray chamber, and the negative pressure pipe connects the dehumidification pipe and the negative pressure pump.

[0011] By adopting the above technical solution, a negative pressure pump and a negative pressure pipe are added to provide a stable negative pressure suction for the dehumidification pipe, ensuring that water mist is continuously and efficiently extracted and discharged, thereby enhancing the reliability and dehumidification effect of the dehumidification system.

[0012] Optionally, the dehumidification assembly further includes a mounting plate located within the spray channel and between the conveyor belt and the receiving chamber, with the sponge block fixed to the mounting plate.

[0013] By adopting the above technical solution, the sponge block is fixed by an installation plate, making the installation of the sponge block more stable and easier to maintain and replace, thereby ensuring that the water absorbed by the sponge block can be smoothly guided to the containment chamber.

[0014] Optionally, the bottom end of the sponge block gradually tapers and forms a V-shape.

[0015] By adopting the above technical solution, the bottom of the sponge block is designed as a gradually contracting V-shape, which is conducive to gathering and guiding the absorbed water droplets to drip down along the tip into the containment chamber, thereby accelerating the drainage speed.

[0016] Optionally, the spray assembly includes a spray pipe, a spray pump, and a water supply pipe. The spray pump is located outside the spray chamber, and one end of the spray pipe is connected to the spray pump, while the other end extends into the spray channel and is located above the conveyor belt.

[0017] By adopting the above technical solution, the sprinkler pump is placed outdoors, which facilitates maintenance and reduces indoor noise and space occupation. The sprinkler pipes are inserted above the sprinkler channel, with a reasonable layout that facilitates comprehensive spray coverage.

[0018] Optionally, there are multiple water mist nozzles connected side by side to the spray pipe.

[0019] By adopting the above technical solution, multiple water mist nozzles are arranged side by side on the spray pipe to form a uniform and continuous water mist coverage zone, ensuring that dumplings at different positions on the conveyor belt can receive uniform spraying, thereby improving production efficiency.

[0020] Optionally, a drain pipe is also included, which passes through the spray chamber and connects to the containment chamber.

[0021] By adopting the above technical solution and connecting the drainage pipe to the storage tank, the collected wastewater can be discharged regularly without removing the storage tank. This simplifies operation and improves the convenience and hygiene of equipment maintenance.

[0022] Optionally, it also includes a cleaning component, which includes a cleaning plate and a cleaning bin. The cleaning bin is located inside the spray channel and below the conveyor belt. The cleaning plate is disposed on the cleaning bin and is used to scrape off the adhesive dough on the conveyor belt.

[0023] By adopting the above technical solution, residual dough that may adhere to the surface of the conveyor belt due to the mixing of water and flour is scraped off by the impurity removal plate, preventing its accumulation from affecting the operation of the conveyor belt or contaminating subsequent dumplings, thus ensuring the cleanliness of the production process and the product quality of the dumplings.

[0024] Optionally, the impurity removal assembly further includes impurity removal springs located between the impurity removal chamber and the impurity removal plate, and there are multiple impurity removal springs arranged side by side.

[0025] By adopting the above technical solution, multiple parallel cleaning springs are set between the cleaning plate and the cleaning bin, so that the cleaning plate has a certain elastic clamping force and buffer space. This can effectively scrape away debris and reduce resistance to the conveyor belt.

[0026] In summary, this application includes at least one of the following beneficial technical effects: The automated spraying device for quick-frozen dumplings before freezing provided by this application achieves efficient and uniform spraying operations through integrated and automated spraying and dehumidification design, significantly improving the appearance quality of dumplings and the speed matching capability of the production line; at the same time, its efficient water mist control and recovery mechanism reduces workshop humidity, improves the production environment, and saves water resources; the additional impurity removal function further ensures the cleanliness and stable operation of the equipment, and overall has outstanding advantages such as high degree of automation, good spraying quality, environmental friendliness, and convenient maintenance.

[0029] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0030] This application discloses an automated spraying device for quick-frozen dumplings before freezing.

[0031] refer to Figures 1 to 3 An automated pre-freezing spraying device for quick-frozen dumplings includes a spray chamber 1, a conveyor belt 2, a spraying assembly, and a dehumidification assembly. The spray chamber 1 has a spraying channel, and the conveyor belt 2 is located within the spraying channel and is used to transport the shaped dumplings. The spraying assembly sprays water mist onto the dumplings on the conveyor belt 2. After the water mist lands on the dumplings, they enter the freezing process. To prevent the water mist from affecting the environment outside the spray chamber 1, the dehumidification assembly removes the water mist from the outside of the spray chamber 1.

[0032] Conveyor belt 2 is a common structure and is located inside the spray channel. Conveyor belt 2 is connected to the external conveyor structure and together they transport the formed dumplings. Conveyor belt 2 is located inside the spray channel only so that the dumplings placed inside the conveyor belt 2 can enter the spray channel and receive water mist.

[0033] refer to Figures 1 to 3The spray assembly includes water mist nozzles 3, spray pipes 9, a spray pump 10, and a water supply pipe 11. The spray pump 10 is located outside the spray chamber 1. One end of the spray pipe 9 is connected to the spray pump 10, and the other end extends into the spray channel. Multiple water mist nozzles 3 are arranged side-by-side on the spray pipe 9, positioned above the conveyor belt 2. The water mist nozzles 3 communicate with the interior of the spray pipe 9 and are used to spray water mist onto the water droplets on the conveyor belt 2. The row of water mist nozzles 3 ensures that all the water droplets on the conveyor belt 2 receive water mist, forming a uniform water film on the surface of the water droplets. The water supply pipe 11 connects to an external water source and is also connected to the spray pump 10.

[0034] refer to Figures 3 to 4 The dehumidification assembly includes a sponge block 4, a containment chamber 5, a fog curtain 6, a dehumidification pipe 7, a negative pressure pump, and a negative pressure pipe. The container 5 is located inside the spray channel and below the conveyor belt 2. The sponge block 4 is located inside the spray channel and between the conveyor belt 2 and the container 5. The top of the sponge block 4 contacts the lower part of the conveyor belt 2. Since the water mist will be sprayed on the conveyor belt 2, the sponge block 4 can remove excess water droplets on the conveyor belt 2. After passing through the sponge block 4, the water droplets will enter the container 5. There are two fog curtains 6, which are respectively set at the two ends of the spray channel. The fog curtains 6 do not block the entry of the formed dumplings, but block some of the water mist from flowing into the outside of the spray chamber 1. This method not only reduces water consumption, but also avoids affecting the environment outside the spray chamber 1. The negative pressure pump is located outside the spray chamber 1. One end of the negative pressure pipe is connected to the negative pressure pump, and the other end is connected to the dehumidification pipe 7. The dehumidification pipe 7 has an air intake hole facing the ground. Through the cooperation of the negative pressure pump, the negative pressure pipe and the dehumidification pipe 7, the water mist passing through the fog curtain 6 can be absorbed by the negative pressure, thereby further reducing the water mist that escapes into the outside of the spray chamber 1.

[0035] It should be noted that, in order to avoid mutual interference between the fog curtain and the dumplings, there is a gap between the bottom of the fog curtain and the conveyor belt, through which the dumplings enter the conveyor belt.

[0036] To ensure that the water droplets on the sponge block 4 can smoothly enter the receiving chamber 5, the initial assembly is also equipped with a mounting plate 8. The mounting plate 8 is fixed in the spray channel and has mounting holes. The middle part of the sponge block 4 passes through the mounting holes, and the bottom of the sponge block 4 gradually tapers into a V-shape. The mounting plate 8 is located above the receiving chamber 5, which can prevent the sponge block 4 from directly contacting the receiving chamber 5 and causing the water on the sponge block 4 to flow into the outside of the receiving chamber 5. The gradual taper of the bottom of the sponge block 4 is conducive to the accumulation of water in the sponge, which then flows into the receiving chamber 5 quickly.

[0037] In order to drain the sewage inside the storage chamber 5 after it is removed, a drain pipe 12 is installed on the spray chamber 1. One end of the drain pipe 12 is connected to the inside of the storage chamber 5, and the other end extends into the outside of the spray chamber 1.

[0038] During the transport of dumplings on conveyor belt 2, a small amount of flour accumulates. This flour adheres to the conveyor belt 2 after encountering water. If the adhered dough is not removed, the dumplings may break during operation. Therefore, a dust removal component is used to remove the adhered dough from conveyor belt 2. The dust removal component is located within the spray channel and includes a dust removal plate 13, a dust removal bin 14, and a dust removal spring 15. The dust removal bin 14 is located below conveyor belt 2, and the dust removal plate 13 is located between the dust removal bin 14 and conveyor belt 2. One end of the dust removal spring 15 is connected to the bottom of the dust removal plate 13. The dust removal plate 13 contacts the bottom of conveyor belt 2 and is used to scrape off the dough adhering to conveyor belt 2. The fallen dough falls into the dust removal bin 14. The dust removal spring 15 causes the dust removal plate 13 to avoid contact, thereby reducing the resistance experienced by conveyor belt 2 during operation.

[0039] In addition, in order to improve the stability of the impurity removal plate 13 and guide the impurity removal plate 13 during movement, the impurity removal assembly also includes a guide rod, one end of which is connected to the bottom of the impurity removal plate 13 and the other end is inserted into the impurity removal chamber 14.

[0040] To improve operational convenience and facilitate the removal of the impurity removal chamber 14 and the storage chamber 5 by operators, a window is provided on the side of the spray chamber 1 and is sealed by a cover plate and hinges.

[0041] The implementation principle of the automated spraying device for quick-frozen dumplings in this embodiment is as follows: Dumplings are conveyed to the conveyor belt by an external conveyor system and enter the spraying channel at a uniform speed. At this time, the water mist nozzles located above the channel are activated, spraying a uniform and fine water mist onto the dumplings on the conveyor belt below. The water mist adheres to the surface of the dumplings, forming a uniform liquid film or pre-crystallized layer that helps with subsequent quick-freezing. During this process, the sponge block remains in contact with the bottom of the conveyor belt, continuously absorbing and wiping away excess moisture from the surface of the conveyor belt to prevent it from dripping. At the same time, the fog curtain blocks some of the water mist from escaping outside the spraying room, and the dehumidification pipe sucks away the water mist that has passed through the fog curtain, further reducing the concentration of water mist escaping outside the spraying room.

[0042] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
