[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number or order of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0029] See also Figure 1~Figure 4 The embodiment of the present application provides a betel nut processing gluing device, which includes a feeding device 10, a mixing device 20, a first storage device 30 and a second storage device 40. When the feeding device 10 is connected to the mixing device 20, the betel nut is transported into the mixing device 20; when the first storage device 30 is connected to the mixing device 20, gelatin is sprayed into the mixing device 20; when the second storage device 40 is connected to the mixing device 20, an additive is sprayed into the mixing device 20; the first storage device 30 includes a first tank body 31 and a heat preservation structure 32 arranged on the first tank body 31, and the heat preservation structure 32 is used to keep the gelatin warm.

[0030] Generally, the outer surface of betel nut is rough and has poor finish, so betel nut food generally needs to apply a layer of glue on the outer surface of betel nut, which is called glue coating; after the glue gels, a layer of bright and sweet and pleasant gel coat is formed, which not only makes the appearance of betel nut products bright and shiny, but also improves the flavor of the product, and improves the sensory quality of betel nut food as a whole. The glue is generally prepared using edible gelatin, sweeteners, edible flavors and spices, etc. The additives in the embodiments of the present application refer to sweeteners, edible flavors and spices, etc.

[0031] The gluing equipment for betel nut processing according to the embodiment of the present application includes a feeding device 10 , a mixing device 20 , a first storage device 30 and a second storage device 40 .

[0032] In the embodiment of the present application, when the feeding device 10 is connected to the mixing device 20, the betel nuts that need to be glued are transported to the mixing device 20. The feeding device 10 may include a logistics line and a hopper 11 for transporting betel nuts. The logistics line may be, for example, a conveyor belt that can continuously transport the betel nuts to the hopper 11; the logistics line here may also be any other structure that can transport the betel nuts to the hopper 11. A valve, such as a pneumatic gate valve, may be provided between the hopper 11 of the feeding device 10 and the mixing device 20, so that the hopper 11 and the mixing device 20 are connected only when the quantity or weight of the betel nuts transported to the hopper 11 meets the requirements, and the betel nuts are transported to the mixing device 20. After all the betel nuts in the hopper 11 enter the mixing device 20, the valve between the two can be closed, and the hopper 11 continues to feed, preparing for the next betel nut demand of the mixing device 20. It is understandable that when there is no requirement for the quantity and weight of betel nuts, there may be no valve between the hopper 11 and the mixing device 20 , and the betel nuts transported into the hopper 11 may directly enter the mixing device 20 .

[0033] In addition, the mixing device 20 is used to apply glue to the surface of the betel nut, and the glue here includes gelatin and additives. In some embodiments, the mixing device 20 can be a drum, which can spray the glue on all the surfaces of the betel nuts through its own rotation; in other embodiments, the mixing device 20 itself may not rotate, but a stirrer is installed inside it, and the stirrer can make the sprayed glue applied to the surface of all the betel nuts by stirring the betel nuts in the mixing device 20. The mixing device 20 can also be other structures that can apply glue to the surface of the betel nuts. It can be understood that the mixing device 20 is preferably able to evenly apply the glue on the outer surface of the betel nut.

[0034] In the embodiment of the present application, gelatin is stored in the first tank body 31 of the first storage device 30. It can be understood that the first tank body 31 and the mixing device 20 can be in an openable and closable communication relationship. For example, a pneumatic valve can be provided between the first tank body 31 and the mixing device 20. When gelatin needs to be sprayed in the mixing device 20, the pneumatic valve is controlled to open, and when gelatin does not need to be sprayed, the pneumatic valve is controlled to close. In addition, a discharge pipe is connected to the bottom of the first tank body 31, and a valve is provided between the discharge pipe and the first tank body 31. At the end of production, the valve between the two is opened to discharge the gelatin in the first tank body 31 into a recovery container.

[0035] Similarly, the second material storage device 40 and the mixing device 20 are in an openable and closable communication relationship, for example, a pneumatic valve can be provided between the second material storage device 40 and the mixing device 20. When the additive needs to be sprayed in the mixing device 20, the pneumatic valve is controlled to open, and when the additive does not need to be sprayed, the pneumatic valve is controlled to close. In addition, a discharge pipe is connected to the bottom of the second material storage device 40, and a valve is provided between the discharge pipe and the second material storage device 40. At the end of production, the valve between the two is opened to discharge the additive in the second material storage device 40 into a recovery container.

[0036] In addition, it can be understood that liquid level sensors are installed at the top and bottom of the first tank body 31. When gelatin is injected into the first tank body 31, when the gelatin position in the first tank body 31 reaches the liquid level sensor at the top, the injection is controlled to stop; when gelatin is sprayed into the mixing device 20, when the gelatin position in the first tank body 31 reaches the liquid level sensor at the bottom, the gelatin is automatically replenished into the first tank body 31. Similarly, liquid level sensors can also be installed at the top and bottom of the second storage device 40 to facilitate the liquid level of the additive inside the detector. The detection principle is the same as that of gelatin detection, which will not be repeated here.

[0037] In the embodiment of the present application, a heat-insulating structure 32 is provided on the first tank body 31, and the heat-insulating structure 32 can insulate the gelatin in the first tank body 31 to prevent the gelatin from being stratified or even agglomerated. In some embodiments, the heat-insulating structure 32 can be a heat-insulating layer provided on the inside and / or outside of the first tank body 31, or the shell of the first tank body 31 can be provided as a double-layer structure that can be used for heat-insulating. The heat-insulating structure 32 can also select any other structure that can insulate the gelatin in the first tank body 31.

[0038] The gluing equipment for betel nut processing provided in the embodiment of the present application utilizes a feeding device 10 to convey betel nut into a mixing device 20, utilizes a first storage device 30 and a second storage device 40 to store gelatin and additives respectively, and conveys the gelatin and additives respectively into the mixing device 20 and sprays them onto the betel nut, thereby avoiding the problem of unstable quality of betel nut products caused by manual addition of gelatin and additives based on experience, and realizing the equipmentization and automation of the gluing process; in addition, a heat-insulating structure 32 is provided on the first tank body 31, which can keep the gelatin warm, thereby avoiding the problem of stratification or even agglomeration caused by long-term storage of gelatin.

[0039] In some embodiments, the feeding device 10 includes a hopper 11 and a weighing module 12, the weighing module 12 is arranged below the hopper 11 to measure the weight of the betel nut in the hopper 11, and the hopper 11 is connected to the mixing device 20 to transport the betel nut to the mixing device 20. It can be understood that the material line transports the betel nut to the hopper 11, and the weighing module 12 weighs the betel nut. When the set weight is reached, the feeding is stopped. According to the weighed weight of the betel nut, the weight of the gelatin and additives required to be sprayed can be converted. After stopping the feeding, the valve between the hopper 11 and the mixing device 20 is opened to transport the betel nut to the mixing device 20. The valve here can be a pneumatic gate valve. In other embodiments, a transmission mechanism is installed between the hopper 11 and the mixing device 20, and the transmission mechanism includes a motor and a roller, which can more quickly transport the betel nut from the hopper 11 to the mixing device 20.

[0040] In some embodiments, the gluing device further includes a hot water supply device 50, which delivers hot water to the first storage device 30 when the hot water supply device 50 is connected to the first storage device 30. That is, the first storage device 30 is kept warm or cleaned by the hot water supplied by the hot water supply device 50. It can be understood that the hot water supply device 50 can be a heating water tank, which is connected to an external water source to control water replenishment. The heating water tank is provided with a float switch. When the water level in the heating water tank reaches a high liquid level, the float switch is closed and water inlet is stopped; when the water level reaches a low liquid level, the float switch is opened and water replenishment begins. When the first storage device 30 is kept warm, the water in the heating water tank is generally heated to about 70°C; when the first storage device 30 is cleaned, the water in the heating water tank is generally heated to about 95°C. In the embodiment of the present application, a high-pressure hot water pump 51 and a valve are installed at the hot water output end of the hot water supply device 50. The valve is a pneumatic valve for controlling the output of hot water.

[0041] In some embodiments, the insulation structure 32 includes a shell covering the inner and / or outer sides of the first tank body 31, a gap is formed between the shell and the first tank body 31, and the hot water supply device 50 keeps the first tank body 31 warm when it is connected to the gap. It can be understood that the first tank body 31 is surrounded by its wall body, the shell of the insulation structure 32 is arranged on the inner and / or outer sides of the wall body, and a gap is formed between the wall body, and the hot water supply device 50 passes hot water into the gap to keep the first tank body 31 warm, so that the gelatin in the first tank body 31 will not be stratified or even agglomerated. The wall of the first tank body 31 and the shell of the insulation structure 32 can be made of different materials, or they can be set to the same material; they can be processed separately and then connected, or they can be processed in one piece. When the two are made of the same material, the first tank body 31 and the insulation structure 32 are preferably an integrated structure. A valve can be installed between the hot water supply device 50 and the gap to control the hot water supply device 50 to communicate with the gap when necessary.

[0042] In other embodiments, the first material storage device 30 further includes a double-layer delivery pipe 33 for connecting the first tank 31 and the mixing device 20, and the double-layer delivery pipe 33 is formed with an interlayer, and hot water is delivered to the interlayer when the interlayer is connected to the hot water supply device 50. It can be understood that the hot water supply device 50 can deliver hot water to the interlayer of the double-layer delivery pipe 33 to ensure the temperature of the double-layer delivery pipe 33, so that the gelatin can flow smoothly therein to avoid agglomeration. A valve, such as a pneumatic valve, can be provided between the hot water supply device 50 and the interlayer to control the hot water supply device 50 to communicate with the interlayer when necessary.

[0043] Furthermore, the first storage device 30 also includes a gelatin reflux pipe 34, which refluxes gelatin when the gelatin reflux pipe 34 is connected to the double-layer conveying pipe 33 and the first tank body 31 respectively. In the production process of betel nut food, when the downtime exceeds 30 minutes, the gelatin in the double-layer conveying pipe 33 needs to be refluxed and circulated to prevent the gelatin from caking in the pipe. One end of the gelatin reflux pipe 34 is connected to the double-layer conveying pipe 33, and the other end is connected to the first tank body 31, so that the gelatin in the double-layer conveying pipe 33 and the gelatin in the first tank body 31 can circulate. It can be understood that valves, such as pneumatic valves, are respectively provided between the double-layer conveying pipe 33 and the gelatin reflux pipe 34 and between the double-layer conveying pipe 33 and the mixing device 20, so that the double-layer conveying pipe 33 can be controlled to be connected to one of the two.

[0044] In some embodiments, the hot water supply device 50 cleans the first tank body 31 when it is connected to the first tank body 31. In the embodiment of the present application, the hot water supply device 50 provides hot water to clean the first tank body 31, and the temperature of the hot water used for cleaning is generally around 95°C. The end of the pipe connecting the hot water supply device 50 and the first tank body 31 extending into the first tank body 31 is equipped with a high-pressure rotating nozzle 52, so that hot water can be sprayed into the first tank body 31 to clean it. It can be understood that a valve, such as a pneumatic valve, can be installed between the hot water supply device 50 and the first tank body 31, so as to control the valve to open when the first tank body 31 needs to be cleaned.

[0045] In some embodiments, the gluing device further includes a hot water supply device 50, which cleans the second material storage device 40 when the hot water supply device 50 is connected to the second material storage device 40. Similarly, the hot water supply device 50 is connected to the second material storage device 40 through a pipeline to transport hot water into the second material storage device 40 to clean it; a high-pressure rotating nozzle 52 is installed at the end of the pipeline extending into the second material storage device 40, so as to spray hot water into the second material storage device 40 to clean it. It can be understood that a valve, such as a pneumatic valve, can be installed between the hot water supply device 50 and the second material storage device 40, so as to control the valve to open when the second material storage device 40 needs to be cleaned.

[0046] In some embodiments, the gluing device further comprises a hot water supply device 50, and the hot water supply device 50 cleans the feeding device 10 when it is connected to the feeding device 10. In other embodiments, the hot water supply device 50 cleans the mixing device 20 when it is connected to the mixing device 20. Similarly, the hot water supply device 50 is connected to the feeding device 10 and / or the mixing device 20 through a pipeline to transport hot water into the feeding device 10 and / or the mixing device 20 to clean it; a high-pressure rotating nozzle 52 is installed at the end of the pipeline extending into the feeding device 10 and / or the mixing device 20, so as to spray hot water into the feeding device 10 and / or the mixing device 20 to clean it. It can be understood that a valve, such as a pneumatic valve, can be installed between the hot water supply device 50 and the feeding device 10 and / or the mixing device 20, so as to control the valve to open when the feeding device 10 and / or the mixing device 20 needs to be cleaned.

[0047] That is to say, referring to Figure 4 In some embodiments, the hot water supply device 50 can provide hot water to clean the first tank 31, the second storage device 40, the feeding device 10 and the mixing device 20, and they are all selectively connected through valves. When necessary, the valves are controlled to open, and each device can be automatically cleaned; the problem of the difficulty and time spent in cleaning the existing equipment is solved, and labor costs are also saved. In addition, the hot water supply device 50 is connected to the double-layer conveying pipeline 33, and a pneumatic valve is installed between the two, so that the double-layer conveying pipeline 33 can be cleaned when necessary.

[0048] In some embodiments, the first material storage device 30 further includes a first pump body 35 and a first flow meter 36. One end of the first pump body 35 is connected to the first tank body 31, and the other end is connected to the mixing device 20 to pump gelatin. The first flow meter 36 is arranged between the first pump body 35 and the mixing device 20. It can be understood that the first pump body 35 is used to pump gelatin from the first tank body 31 into the mixing device 20, and the first flow meter 36 can measure the pumped gelatin. In other embodiments, the second material storage device 40 includes a second tank body 41, a second pump body 42, and a second flow meter 43. One end of the second pump body 42 is connected to the second tank body 41, and the other end is connected to the mixing device 20 to pump additives. The second flow meter 43 is arranged between the second pump body 42 and the mixing device 20. It can be understood that the second pump body 42 is used to pump additives from the second tank body 41 into the mixing device 20, and the second flow meter 43 can measure the pumped additives. Pneumatic valves are installed between the first flowmeter 36 and the mixing device 20, and between the second flowmeter 43 and the mixing device 20, and the opening and closing of the pneumatic valves are controlled to control whether the first pump body 35 and the second pump body 42 pump gelatin and additives into the mixing device 20. In the embodiment of the present application, the first pump body 35 and the second pump body 42 can both be pneumatic diaphragm pumps; the first flowmeter 36 and the second flowmeter 43 can both be ultrasonic flowmeters.

[0049] In the embodiment of the present application, the measured gelatin and additives are respectively conveyed to the mixing device 20, and can be sprayed according to the demand of gelatin and additives for betel nut in the mixing device 20, thereby avoiding the waste of raw materials and saving costs. In addition, the thickness of the glue on the outer surface of the betel nut can be made appropriate, thereby avoiding the glue from being applied too thick or too thin, which affects the taste and appearance of the betel nut product.

[0050] In some embodiments, the first material storage device 30 further includes a stirring mechanism 37 for stirring gelatin, and the stirring mechanism 37 is installed on the first tank body 31. It can be understood that when the stirring mechanism 37 is turned on, the gelatin in the first tank body 31 can be stirred to prevent the gelatin from being stratified or even agglomerated. The stirring mechanism 37 may include a motor and a stirring blade connected to the motor, and the stirring blade is placed in the gelatin, and when the motor rotates, the stirring blade is driven to stir the gelatin.

[0051] Reference Figure 4 The process flow of the betel nut processing gluing equipment of the present application embodiment is as follows:

[0052] 1. The hot water supply device 50 starts to take in water and heat it. When the water level reaches the high liquid level, the float switch is closed and the water intake is stopped. When the water in the hot water supply device 50 is heated to 70°C, the heating is stopped, the high-pressure hot water pump 51 connected to the hot water supply device 50 is started, and the pneumatic valve between the two is opened. When the pressure reaches 0.4Mpa, the pneumatic valve between the hot water supply device 50 and the first tank body 31 and the double-layer delivery pipe 33 is opened, and the hot water is delivered to the insulation structure 32 on the first tank body 31 and the interlayer of the double-layer delivery pipe 33, and the first tank body 31 and the double-layer delivery pipe 33 are heated and insulated.

[0053] 2. Inject gelatin into the first tank body 31. When the liquid level reaches the liquid level sensor at the top of the first tank body 31, stop injecting. Inject additives into the second tank body 41. When the liquid level reaches the liquid level sensor at the top of the second tank body 41, stop injecting. Open the logistics line to transport betel nuts into the hopper 11, and open the weighing module 12 for weighing. When the weight of the betel nuts in the hopper 11 reaches the set weight, close the logistics line and stop transporting the betel nuts. Calculate the weight of gelatin and additives to be sprayed according to the weight of the betel nuts (10 kg of gelatin and 4 kg of additives are sprayed for every 300 kg of betel nuts, calculated according to this ratio, and the additive is alcohol). Open the mixing device 20 to rotate it, open the pneumatic gate valve between the hopper 11 and the mixing device 20, and the transmission mechanism transports the betel nuts into the mixing device 20; after the feeding is completed, close the pneumatic gate valve and stop feeding; at this time, the logistics line can continue to feed the hopper 11.

[0054] 3. Open the pneumatic diaphragm pump connected to the first tank body 31, open the pneumatic valve between the two, and open the pneumatic valve between the first flowmeter 36 and the mixing device 20, and start quantitatively spraying gelatin into the mixing device 20; at the same time, the pneumatic valve set between the first tank body 31 and the gelatin reflux pipe 34 is in a closed state. When the amount of gelatin sprayed is reached, close the pneumatic diaphragm pump and the pneumatic valves to complete the gelatin spraying step. After 40 seconds, open the pneumatic diaphragm pump connected to the second tank body 41, open the pneumatic valve between the two, and open the pneumatic valve between the second flowmeter 43 and the mixing device 20, and start quantitatively spraying additives into the mixing device 20. When the amount of additive sprayed is reached, close the pneumatic diaphragm pump and the pneumatic valves to complete the additive spraying step. After 10 seconds, control the mixing device 20 to reverse and output the betel nut after gelatinization. In the embodiment of the present application, one production cycle is from the opening of the pneumatic gate valve to the betel nut conveying from the hopper 11 to the mixing device 20 to the betel nut being completely output from the mixing device 20. In the embodiment of the present application, the weight of the betel nut in the hopper 11 is set to 300 kg, and the above production cycle is 4 minutes.

[0055] During the production process, if the downtime of the glue application equipment exceeds 30 minutes, the pneumatic diaphragm pump of the first tank body 31, the pneumatic valve between the two, and the pneumatic valve between the first tank body 31 and the gelatin reflux pipeline 34 can be controlled to open, so that the gelatin circulates in the gelatin reflux pipeline 34 for 2 minutes to prevent the gelatin from agglomerating in the pipeline. After the production is completed, the remaining gelatin in the first tank body 31 and the remaining additives in the second tank body 41 are discharged into the recovery container by opening the pneumatic valve between the first tank body 31 and the recovery container and the pneumatic valve between the second tank body 41 and the recovery container.

[0056] 4. When the production task is completed or the glue-applying equipment needs to be cleaned during the production process, close all pneumatic valves and heat the water in the hot water supply device 50 to 95°C. After the temperature is reached, open the stirring mechanism 37 of the first tank body 31, and open the pneumatic valves between the hot water supply device 50 and the first tank body 31, the second tank body 41, the hopper 11 and the gelatin return pipe 34 respectively, start the pneumatic diaphragm pump connected to the first tank body 31 and the corresponding pneumatic valves, and hot water flows into the first tank body 31, the second tank body 41, the hopper 11 and the gelatin return pipe 34 for cleaning. After 5 minutes of cleaning, control each valve to close.

[0057] Open the pneumatic diaphragm pump and the corresponding pneumatic valve connected to the second tank 41, so that hot water flows into the double-layer delivery pipe 33 and the additive delivery pipe for cleaning. The cleaning time is 10 minutes. After the cleaning is completed, control the valves to close and stop the two pneumatic diaphragm pumps.

[0058] The mixing device 20 is started to reverse, and the corresponding pneumatic valve is opened to spray hot water into the mixing device 20 through the high-pressure rotary nozzle 52 to clean the mixing device 20 for 20 minutes. After the cleaning is completed, all pneumatic valves are stopped to complete the cleaning step of the gluing equipment.

[0059] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
