Description

A chili seed coating machine with a nutrient coating Technical Field

[0001] This utility model relates to the field of breeding equipment technology, specifically a chili seed coating machine with a nutrient coating. Background Technology

[0002] In the pharmaceutical, food, agricultural (such as seed treatment), and chemical industries, coating technology is widely used to apply functional coatings to the surface of granular or pellet-core materials (such as tablets, seeds, and granules) to achieve purposes such as masking taste, moisture protection, slow release, controlled release, improved appearance, or providing protection. Fluidized bed coating technology is widely used due to its high efficiency and good coating uniformity.

[0003] Currently, when seed coating machines are in use, the coating solution has high viscosity, which can cause some solution and seeds to stick to the inside of the coating machine during the coating process. However, most existing seed coating machines do not have a cleaning function. In order to solve the problems existing in the prior art, the utility model with announcement number CN222532190U discloses a cleanable seed coating machine (hereinafter referred to as prior art 1), which includes a base, a tank fixedly connected to the top of the base, a mounting base fixedly connected to the outer end of the tank, a connecting frame fixedly connected to the top of the mounting base, a second drive motor fixedly connected to the upper end of the connecting frame, a lead screw fixedly connected to the output end of the second drive motor, a scraper threaded onto the lead screw, and a sliding rod fixedly connected to the lower end of the connecting frame, with the scraper slidably connected to the sliding rod.

[0004] Although the prior art 1 can clean the tank, when the spiral blades in the prior art 1 are agitating materials with irregular shapes and light particle weight (such as chili seeds), some areas on the surface of the material (such as the bottom, the lower side, and the depressions) may still be blocked for a long time, making it difficult to fully expose and effectively contact the atomized coating droplets, resulting in uneven coating coverage and the existence of coating dead corners or weak areas. Summary of the Invention

[0005] The purpose of this invention is to provide a chili seed coating machine with a nutrient coating. In actual use, it can solve the problem in the prior art that when the stirring mechanism stirs materials with irregular shapes and light weight, some areas on the surface of the material may still be blocked for a long time, making it difficult to fully expose and effectively contact the atomized coating droplets.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A chili seed coating machine with a nutrient coating includes a housing and an air inlet system installed at the bottom of the housing. Inside the housing, a guide pipe and a distribution plate are installed sequentially from top to bottom.

[0008] The distribution plate is provided with a plurality of air holes, and a feeding gap is provided between the guide pipe and the distribution plate. A material dropping area is formed between the guide pipe and the shell. A spraying assembly is installed on the distribution plate, and the spraying assembly is coaxially arranged with the guide pipe.

[0009] A spray ring assembly is mounted on the housing, and the spray ring assembly is positioned above the guide pipe.

[0010] Preferably, the pore density at the position corresponding to the distribution plate and the guide pipe is greater than the pore density at the position corresponding to the distribution plate and the material dropping area.

[0011] Preferably, a heating plate is installed inside the housing, the heating plate is disposed between the air inlet system and the distribution plate, and the heating plate is provided with a plurality of air holes.

[0012] Preferably, the spray ring assembly includes a spray ring body and a plurality of second nozzles disposed on the spray ring body, wherein a liquid cavity communicating with the nozzles is disposed within the spray ring body.

[0013] Preferably, the second nozzle is inclined toward the guide pipe.

[0014] Preferably, the spray ring body is provided with a material guiding part, and the material guiding part is provided with a downwardly inclined material guiding slope.

[0015] Preferably, a telescopic device is installed on the distribution plate, which is used to drive the guide pipe to move vertically.

[0016] Preferably, a baffle is installed on the distribution plate, and the baffle is coaxially arranged with the spraying assembly.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this invention, when the material in the guide tube moves under the propulsion of the airflow, the atomized coating liquid is sprayed into the high-speed upward material flow by the spraying component set in the guide tube, so that the coating liquid droplets can coat the material after contacting it.

[0019] During the settling process, irregular materials (seeds) can slowly descend under the influence of relatively gentle airflow and gravity, and tumble fully, thus exposing the material surface. This allows the spray ring assembly located above the guide pipe (settling area) to spray coating liquid droplets again onto the surface of the material that has moved outside the guide pipe and is settling downwards. This ensures that areas of the material that are difficult to cover by the spraying assembly in the guide pipe, such as the back, sides, and irregular depressions, can be covered by the coating liquid droplets sprayed by the spray ring assembly.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Referring to Figures 1-3, this embodiment discloses a seed coating device for coating chili seeds with a nutrient coating. Specifically, it is a chili seed coating machine with a nutrient coating, including a housing 101 and an air inlet system 102 installed at the bottom of the housing 101. A guide pipe 103 and a distribution plate 104 are installed in the housing 101 from top to bottom.

[0034] The distribution plate 104 is provided with a plurality of air holes, and a feeding gap is provided between the guide pipe 103 and the distribution plate 104. A material dropping area is formed between the guide pipe 103 and the housing 101. A spraying assembly 106 is installed on the distribution plate 104, and the spraying assembly 106 is coaxially arranged with the guide pipe 103.

[0035] A spray ring assembly 105 is installed on the housing 101, and the spray ring assembly 105 is disposed above the guide pipe 103.

[0036] In this embodiment, the spraying assembly 106 includes a first nozzle 117 and a material source device. The material source device is an existing device for inputting coating liquid into the first nozzle 117, and its structure and function will not be described in detail here. The air inlet system 102 is used to input hot air into the housing 101. The hot air enters the guide pipe 103 and the material dropping area through the air holes provided on the distribution plate 104. The material located in the central area directly below the guide pipe 103 is subjected to high speed and high flow rate. The powerful airflow accelerates vertically upward through the guide pipe 103. As the material inside the guide pipe 103 moves under the impetus of the airflow, the atomized coating liquid is sprayed onto the high-speed upward material flow by the spraying assembly 106 installed inside the guide pipe 103, so that the coating liquid droplets can coat the material after contacting it. After the material is coated by the coating droplets, the airflow speed decreases significantly after it rises outside the guide pipe 103. As the material gradually loses its upward momentum, it can settle under its own gravity. The material entering the settling area is fluidized again by the airflow input into the settling area and moves towards the feed gap, thereby being circulated and lifted into the guide pipe 103 for the next spraying; the irregular material seeds can slowly descend under the action of relatively gentle airflow and gravity during the settling process, and fully tumble, fully exposing the material surface; so that the spray ring assembly 105 set in the settling area above the guide pipe 103 can spray the coating liquid again onto the surface of the material that has moved out of the guide pipe 103 and dispersed downwards. Droplets; ensuring that areas such as the back, lower sides, and irregular depressions of the material that are difficult to be covered by the spraying assembly 106 in the guide pipe 103 can be covered by the coating droplets sprayed by the spraying ring assembly 105; in this embodiment, the air inlet system 102 is a conventional air source device that can input hot air into the device in the prior art. The hot air can also dry the material coated with coating droplets during the process of driving the material, and prevent the material from sticking together after falling into the material dropping area. Its structure and function will not be described in detail here.

[0037] In some embodiments, the pore density at the corresponding positions of the distribution plate 104 and the guide pipe 103 is greater than the pore density at the corresponding positions of the distribution plate 104 and the material dropping area. In this embodiment, the pore density in the area below the guide pipe 103 and corresponding to the guide pipe 103 is relatively high and dense, enabling a high-speed, high-flow-rate vertical upward airflow to be formed within the guide pipe 103. This allows the material to pass through the guide pipe 103 at a high speed, and the first coating is completed in this area by the spraying assembly 106. Conversely, the pore density at the corresponding positions of the distribution plate 104 and the material dropping area is relatively low and sparse, providing a moderate and uniform upward airflow to maintain the fluidized state of the material in the storage area and drive the material to move laterally into the gap at the bottom of the guide pipe 103. Furthermore, the upward airflow in the material dropping area can also delay the material's descent, increase the contact time between the material and the coating droplets sprayed from the spray ring assembly 105, and further dry the falling material.

[0038] In some embodiments, a heating plate 107 is installed inside the housing 101. The heating plate 107 is disposed between the air inlet system 102 and the distribution plate 104, and the heating plate 107 is provided with a plurality of air holes. When the airflow output from the air inlet system 102 passes through the air holes, the heating plate 107 can perform secondary preheating on the airflow that is about to enter the material dropping area and the guide pipe 103, so as to avoid the hot airflow in the air inlet system 102 from being lower than the preset value when the air reaches the bottom of the distribution plate 104 due to heat dissipation of the pipeline or response delay. In this embodiment, the heating plate 107 is a conventional heating device in the prior art that can adjust the heating temperature, and its structure and function will not be described in detail here.

[0039] In some embodiments, the spray ring assembly 105 includes a spray ring body 108 and a plurality of second nozzles 109 disposed on the spray ring body 108. The spray ring body 108 has a liquid cavity communicating with the second part. In this embodiment, the second nozzles 109 are equally spaced along the circumferential direction of the spray ring body 108. The spray ring body 108 is connected to the material source device, which is used to input coating droplets into the liquid cavity, so that the coating droplets can be sprayed out from the second part and sprayed onto the surface of the material that has begun to settle, so that the coating droplets can fully coat the surface of the material.

[0040] In some embodiments, the second nozzle 109 is inclined toward the guide tube 103. After the material is ejected from the expansion port at the top of the guide tube 103, it follows a parabolic trajectory under the action of gravity, moving outward and downward toward the housing 101 and the material settling area, forming a divergent material flow centered on the guide tube 103. By inclinedly arranging the second nozzle 109, the contact area between the coating droplets sprayed from the second nozzle 109 and the material can be increased, thereby increasing the contact time and coating effect between the coating droplets and the material while avoiding affecting the movement of the material toward the material settling area.

[0041] In some embodiments, a material guiding section 110 is provided on the spray ring body 108, and the material guiding section 110 is provided with a downwardly inclined material guiding slope 111. In this embodiment, by providing the material guiding slope 111, a small portion of the material that moves above the spray ring body 108 can be guided by the material guiding slope 111 back to the material dropping area, thus preventing the material from accumulating on the spray ring body 108.

[0042] In some embodiments, a telescopic device 112 is installed on the distribution plate 104, and the telescopic device 112 is used to drive the guide tube 103 to move vertically. In this embodiment, the telescopic device 112 is a conventional telescopic rod mechanism in the prior art. A heat insulation block is installed on the fixed end of the telescopic mechanism, and the fixed end of the telescopic mechanism is connected to the distribution plate 104 through the heat insulation block. The telescopic end of the telescopic mechanism is fixedly connected to the guide tube 103. The telescopic device 112 can drive the guide tube 103 to move vertically up and down, thereby changing the distance between the guide tube 103 and the distribution plate 104, so that the amount of material entering the guide tube 103 is moderate, allowing the material to fully and effectively coat the coating droplets and ensure the coating effect.

[0043] In some embodiments, a baffle 113 is installed on the distribution plate 104, and the baffle 113 is coaxially arranged with the spraying assembly 106. In this embodiment, the baffle 113 is disposed above the first nozzle 117 to protect the first nozzle 117 and prevent the material from colliding with or clogging the first nozzle 117 during the circulating coating process; the baffle 113 is provided with baffle holes, which can block the material but will not affect the spraying of coating droplets by the first nozzle 117.

[0044] In some embodiments, a cover 114 is hinged to the top of the housing 101, and the cover 114 is provided with an exhaust pipe 116 and a handle 115. In this embodiment, the cover 114 is rotatably connected to the housing 101 via a hinge. By opening the cover 114, materials can be placed into or removed from the housing 101. The handle 115 facilitates opening or closing the cover 114. The exhaust pipe is provided with an exhaust groove, which can discharge gas inside the housing 101 to maintain the balance and stability of the airflow inside the tank.

[0045] In some embodiments, a sealing ring is fixedly connected to the bottom end of the cover 114. In this embodiment, the sealing ring is made of rubber material. By setting the sealing ring, it is possible to prevent material from leaking out from the gap between the cover 114 and the can during movement, thus avoiding material waste.

[0046] In some embodiments, the housing 101 and the air intake system 102 are detachably connected by bolts. This detachable connection facilitates the user's cleaning and replacement of the components installed inside the housing 101.

[0047] Although preferred embodiments of the present invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
