[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] The following is combined with Figures 1-5 This invention describes an automated pellet production line.

[0025] like Figure 1 As shown, this utility model provides an automatic pellet production line 1, including: a pretreatment unit 11, a pelletizing unit 12, a curing unit 13, and a screening and cleaning unit 14. The pretreatment unit 11 is used to heat and shear the adhesive solution and core liquid for pelletizing. The pelletizing unit 12 is connected to the pretreatment unit 11 and is used to prepare pellets based on the pretreated adhesive solution and core liquid. The curing unit 13 is connected to the pelletizing unit 12 and is used to cure the pellets output from the pelletizing unit 12. The screening and cleaning unit 14 is connected to the curing unit 13 and is used to sequentially screen and clean the cured pellets.

[0026] It is understood that the pellets in this embodiment are used as food additives, such as pellet products added to jams or jellies.

[0027] The pretreatment unit 11 is used to heat and shear the raw materials (core liquid and glue liquid) of the pellets to form pellet raw materials that meet the process requirements.

[0028] The core fluid, the central content encased within the droplet, is typically a mixture of substances such as fungi, sugars, or oils. During droplet preparation, the core fluid is encapsulated in a gel-like liquid and solidifies upon cooling, forming the droplet and serving as the primary carrier of the drug.

[0029] The gel solution refers to the colloidal solution used to form the outer coating of the pellet. It is usually a mixture of substances such as sodium alginate, gellan gum, agar, and water in a certain proportion. Its function is to encapsulate the core liquid and form the outer gel structure of the pellet, requiring suitable viscosity and solidification characteristics.

[0030] The pellet-dropping unit 12 can be used to receive the core liquid and adhesive liquid processed by the pretreatment unit 11, form shaped pellets by titration, and transport the pellets to the curing unit 13. The curing unit 13 can be used to cure the pellets by immersing them in a curing liquid to form solid or semi-solid pellets, improving the stability of the pellets and preventing them from deforming or breaking due to temperature and humidity changes or physical impacts during storage and transportation. The cured pellets also have moderate hardness, which facilitates processing and packaging in subsequent processes.

[0031] After solidification, the pellets are conveyed to the screening and cleaning unit 14, which screens the pellets. Specifically, the pellets can be screened according to their size and shape to select those that meet production requirements and recycle those that do not. Simultaneously, the screening and cleaning unit 14 also cleans the pellets, rinsing away residual solidification liquid and impurities adhering to the outer wall during pellet production, so that they can be added to the corresponding food products after drying in subsequent processes.

[0032] The automatic granulation production line 1 provided by this utility model consists of a pretreatment unit 11, a pelletizing unit 12, a curing unit 13, and a screening and cleaning unit 14 arranged in sequence. The pretreatment unit 11 can process the core liquid and adhesive liquid to meet the process requirements of pellet production. The processed core liquid and adhesive liquid can be automatically fed into the pelletizing unit 12 to be dropped into pellets, and then cured by the curing unit 13. Finally, the pellets are screened and cleaned by the screening and cleaning unit 14 so that the final produced pellets meet the production requirements. The entire automatic granulation production line 1 can automatically complete the processing, pelletizing, curing, screening, and cleaning of pellets without manual intervention, reducing labor input costs, realizing automated production of pellets, and improving the production efficiency of pellets.

[0033] In some embodiments, such as Figure 1 and Figure 2 As shown, the pretreatment unit 11 includes: a storage tank assembly 111, a heating assembly 112, and a shearing tank 113 connected end to end in sequence; the storage tank assembly 111 is used to store the adhesive liquid and the core liquid; the heating assembly 112 is used to heat the adhesive liquid or the core liquid; the shearing tank 113 is used to shear the heated adhesive liquid or the core liquid and transport the sheared adhesive liquid or the core liquid back to the storage tank assembly 111; the storage tank assembly 111 is also used to connect to the pelletizing unit 12 to transport the sheared adhesive liquid and the core liquid to the pelletizing unit 12.

[0034] It is understood that in this embodiment, the storage tank assembly 111, heating assembly 112, and shearing tank 113 are all connected by corresponding pipelines. Valves, pumps, and other devices can be installed on the pipelines according to the flow rate and direction requirements of the liquid. The storage tank assembly 111 typically includes multiple storage containers for separate storage of the adhesive solution and the core liquid. It is understood that in practical applications, the storage tank assembly 111 can be used to store both the adhesive solution and the core liquid. The solution in the storage tank assembly 111 can be heated in the heating assembly 112 to reach a certain temperature before being fed into the shearing tank 113 for shearing. The shearing tank 113 can perform high-speed shearing, dispersion, emulsification, and mixing of the solution through centrifugation, stirring, etc., to fully break down and mix the components of the adhesive solution or core liquid, forming an adhesive solution or core liquid that meets the requirements of the pellet production process. The sheared adhesive solution or core liquid can then be buffered in the corresponding storage container of the storage tank assembly 111 so that it can be fed into the pellet production unit 12 from the storage tank assembly 111 when needed.

[0035] Specifically, in some embodiments, such as Figure 1 and Figure 2 As shown, the storage tank assembly 111 includes: a first storage tank 1111, a second storage tank 1112, a first switching pipeline 1113, and a second switching pipeline 1114. The first storage tank 1111 is used to store adhesive liquid and is connected to the pelletizing unit 12. The second storage tank 1112 is used to store core liquid and is connected to the pelletizing unit 12. The first switching pipeline 1113 is connected to the first storage tank 1111, the second storage tank 1112, and the heating assembly 112, respectively, and is used to control the heating assembly 112 to selectively receive adhesive liquid in the first storage tank 1111 or core liquid in the second storage tank 1112. The second switching pipeline 1114 is connected to the first storage tank 1111, the second storage tank 1112, and the shearing and dissolving tank 113, respectively, and is used to control the shearing and dissolving tank 113 to selectively introduce adhesive liquid into the first storage tank 1111 or core liquid into the second storage tank 1112.

[0036] In this embodiment, a first switching pipeline 1113 is provided between the first storage tank 1111, the second storage tank 1112 and the heating assembly 112, and a second switching pipeline 1114 is provided between the first storage tank 1111, the second storage tank 1112 and the shearing and dissolving tank 113. The first switching pipeline 1113 and the second switching pipeline 1114 can cooperate with each other, so that the entire pretreatment unit 11 can complete the dissolving and dissolving of the adhesive liquid and the core liquid with a set of heating assembly 112 and shearing and dissolving tank 113.

[0037] Specifically, when processing the adhesive solution, the first switching pipeline 1113 can be controlled to connect the first storage tank 1111 and the heating component 112, and the second switching pipeline 1114 can be controlled to connect the first storage tank 1111 and the shearing and processing tank 113, so that the solution circulates along the path of first storage tank 1111-heating component 112-shearing and processing tank 113-first storage tank 1111, thereby completing the shearing and processing of the adhesive solution.

[0038] Similarly, when processing the core liquid, the first switching pipeline 1113 can be controlled to connect the second storage tank 1112 and the heating component 112, and the second switching pipeline 1114 can be controlled to connect the second storage tank 1112 and the shearing and processing tank 113, so that the solution circulates along the path of the second storage tank 1112-heating component 112-shearing and processing tank 113-second storage tank 1112, thus completing the shearing and processing of the core liquid.

[0039] In practical applications, depending on the requirements, some core liquid or adhesive raw materials can be added to the storage tank (first storage tank 1111 and second storage tank 1112) and the shearing and mixing tank 113 respectively. After the raw materials in the storage tank are heated by the heating component 112, they are passed into the shearing and mixing tank 113 for shearing and are fully mixed with the other raw materials to form an adhesive or core liquid that meets the requirements of pelletizing, and then sent back to the corresponding storage tank.

[0040] For example, when preparing the adhesive solution, an appropriate amount of water can first be introduced into the first storage tank 1111. The water circulates through the heating component 112 and the shearing mixing tank 113, and is heated to the required temperature. Then, adhesive raw materials (such as sodium alginate, gellan gum, agar, etc.) are added to the shearing mixing tank 113, and the mixture is circulated and stirred for a certain period of time. After the mixture is uniformly prepared, all the adhesive solution is introduced into the first storage tank 1111 for storage. Furthermore, the first storage tank 1111 can be a jacketed heating tank, and the first storage tank 1111 activates the stirring and heating / insulating functions of the adhesive solution during storage.

[0041] When preparing the core liquid, an appropriate amount of oil can first be introduced into the second storage tank 1112. The oil circulates through the heating component 112 and the shearing mixing tank 113, and is heated to the required temperature. Then, the core raw material (such as fungi, sugars, or oils) is added into the shearing mixing tank 113. After circulating and stirring for a certain period of time until the mixture is uniformly prepared, all the core liquid is then introduced into the second storage tank 1112 for storage. The second storage tank 1112 can be a jacketed heating tank. During the storage of the adhesive liquid, the second storage tank 1112 activates the stirring and heating / insulating functions of the adhesive liquid.

[0042] Furthermore, the shearing tank 113 can be connected to a circulating cleaning system. After the core liquid or adhesive liquid is treated, the shearing tank 113, the first switching pipeline 1113, and the second switching pipeline 1114 are cleaned online to facilitate the switching of the material to be treated.

[0043] In some embodiments, such as Figure 1 and Figure 3 As shown, the pellet dropping unit 12 includes: a pellet dropping machine 121, a pellet dropping conveyor line 122, and a detector 123; the pellet dropping machine 121 is connected to the pretreatment unit 11; the pellet dropping conveyor line 122 is used to transport the pellets output by the pellet dropping machine 121 to the curing unit 13; the detector 123 is set on the pellet dropping conveyor line 122 and is communicatively connected to the pellet dropping machine 121; the detector 123 is used to detect the diameter of the pellets located on the pellet dropping conveyor line 122, and the pellet dropping machine 121 is used to adjust its own operating parameters based on the diameter signal fed back by the detector 123.

[0044] In this embodiment, the pelletizing machine 121 typically includes a glue tank, a core liquid tank, a dropping head, and a cooling assembly. The glue tank is connected to the first storage tank 1111 of the pretreatment unit 11 to receive and buffer the glue used for pellet production. The core liquid tank is connected to the second storage tank 1112 of the pretreatment unit 11 to receive and buffer the core liquid used for pellet production. The dropping head is used to drop pellets, and the temperature of the output pellets is between 70 and 80°C. The cooling assembly cools the pellets output from the dropping head. The pellet conveying line 122 is used to convey the cooled pellets to the curing unit 13. Exemplarily, the cooling assembly can be located on the pellet conveying line 122 (e.g., below the pellet conveying line 122) to cool the passing pellets.

[0045] Meanwhile, by setting a detector 123 on the pellet conveying line 122, the detector 123 can be a laser measuring instrument. The laser measuring instrument can be used to detect the diameter of the pellets on the pellet conveying line 122, and generate corresponding data signals based on the detection results to feed back to the control system of the pellet machine 121. The control system of the pellet machine 121 adjusts the operating parameters of the pellet machine 121 (including but not limited to pellet speed, air pressure, etc.) according to the preset standard diameter of the pellets (usually a range value) and the diameter signal fed back by the detector 123, so that the pellets output by the pellet machine 121 meet the production requirements.

[0046] Furthermore, the adhesive tank and the first storage tank 1111 can be connected by a pipeline, which is equipped with a valve group and a pump group to control the amount of adhesive entering the adhesive tank. A low liquid level sensor can be installed in the adhesive tank. The low liquid level sensor is connected to the control system of the valve group and pump group between the adhesive tank and the first storage tank 1111. When the adhesive tank reaches the set low liquid level, the pump group and valve group are controlled to replenish the adhesive tank.

[0047] Similarly, the core liquid tank and the second storage tank 1112 can also be connected by a pipeline, which is equipped with a valve group and a pump group. A low liquid level sensor can also be installed in the core liquid tank. The low liquid level sensor is connected to the control system of the valve group and the pump group between the core liquid tank and the second storage tank 1112 so as to realize the automatic replenishment of the core liquid in the core liquid tank.

[0048] In some embodiments, such as Figure 1 and Figure 4 As shown, the curing unit 13 includes: a collection hopper 131, a curing barrel 132, and a curing liquid supply assembly 133; the collection hopper 131 is located at the output end of the droplet unit 12 and is used to receive the droplets output by the droplet unit 12; the curing barrel 132 is located below the collection hopper 131 and is used to receive and cure the droplets in the collection hopper 131, and to pass the cured droplets into the screening and cleaning unit 14; the curing liquid supply assembly 133 is connected to the curing barrel 132 and is used to input curing liquid into the curing barrel 132.

[0049] In this embodiment, the collecting hopper 131 can be funnel-shaped. The flared opening at the upper end of the collecting hopper 131 is used to receive the droplets output from the droplet conveying line 122 of the droplet unit 12. After the droplets enter the collecting hopper 131, they fall into the curing tank 132 from the narrow opening at the lower end. At the same time, the curing tank 132 is also connected to the curing liquid supply component 133 so that curing liquid can be introduced into the curing tank 132 through the curing liquid supply component 133. After the droplets are soaked in the curing liquid for a period of time, they form solid or semi-solid droplets. The cured droplets can be introduced into the screening and cleaning unit 14 through the curing tank 132 for screening and cleaning.

[0050] Alternatively, in some embodiments, such as Figure 1 and Figure 4 As shown, there are multiple curing barrels 132; the collecting hopper 131 is configured to move between the multiple curing barrels 132 for selectively introducing the pellets into one of the multiple curing barrels 132; the curing liquid supply assembly 133 includes: a curing liquid tank 1331 and a third switching pipeline 1332; the curing liquid tank 1331 is used to store the curing liquid; the third switching pipeline 1332 is connected to the curing liquid tank 1331 and each of the curing barrels 132 respectively, for controlling the curing liquid tank 1331 to selectively introduce the curing liquid into one of the multiple curing barrels 132.

[0051] It is understandable that the pellets need to be soaked in the curing liquid for a period of time before they can be cured. In this embodiment, multiple curing tanks 132 are set up so that the curing tank 132 currently being fed can be switched according to the needs during the production process, thereby achieving continuous production and improving production efficiency. Specifically, when the pellets and curing liquid in some of the curing tanks 132 reach the maximum capacity of the curing tank 132 and can no longer receive pellets or curing liquid, the collecting hopper 131 can be controlled to move to the top of another empty curing tank 132 to allow the pellets to be fed into the empty curing tank 132. At the same time, the third switching pipeline 1332 also controls the opening and closing of its own valve group to synchronously feed the curing liquid into the empty curing tank 132, so that multiple curing tanks 132 can take turns to carry out the "feeding-soaking-discharging" process to achieve continuous production curing.

[0052] It is understandable that the curing liquid tank 1331 can also be a jacketed heating tank, so that the various components of the curing liquid can be added to the curing liquid tank 1331, and the components can be fully dissolved and mixed to form the curing liquid through heating, heat preservation and stirring.

[0053] Specifically, the collecting hopper 131 may be equipped with a driving device, which can drive the collecting hopper 131 to move between each curing barrel 132; optionally, the shape of the upper flared opening of the collecting hopper 131 may be reasonably set so that the collecting hopper 131 can still maintain connection with the output end of the droplet unit 12 during the movement.

[0054] In some embodiments, the curing barrel 132 includes: a barrel body 1321 and a bottom plate 1322; the bottom of the barrel body 1321 is provided with a discharge port; the bottom plate 1322 is provided at the discharge port and is used to open and close the discharge port; the bottom plate 1322 is provided with a liquid discharge port, which is used to discharge the curing liquid.

[0055] In this embodiment, the curing tank 132 can be set above the screening and cleaning unit 14. By setting a bottom plate 1322 with an openable discharge port at the bottom of the tank body 1321, and setting an openable liquid outlet on the bottom plate 1322, the curing tank 132 can be used to receive droplets and curing liquid and soak them when the bottom plate 1322 closes the discharge port and the liquid outlet is also closed. After curing, the liquid outlet of the bottom plate 1322 can be opened first to discharge most of the curing liquid, and then the discharge port can be opened through the bottom plate 1322 so that the cured droplets fall from the discharge port into the screening and cleaning unit 14.

[0056] In some embodiments, the barrel body 1321 is further provided with a driving component connected to the bottom plate 1322. The driving component can be a hydraulic device, which can drive the bottom plate 1322 to open and close the discharge port. A valve can be installed inside the discharge port to open and close the discharge port.

[0057] In some embodiments, such as Figure 1 and Figure 5 As shown, the screening and cleaning unit 14 includes: a cleaning container 141, a vibrating screen 142, and a spray assembly 143; the cleaning container 141 is used to receive the solidified pellets; the vibrating screen 142 is disposed in the cleaning container 141 and is used to screen the solidified pellets; the spray assembly 143 is used to spray the pellets in the cleaning container 141.

[0058] In this embodiment, the cleaning container 141 can be positioned below the curing tank 132 to receive the cured pellets discharged from the curing tank 132. The pellets first fall onto the vibrating screen 142 inside the cleaning container 141. The vibrating screen 142 vibrates continuously to drive the pellets to move continuously on the screen. The shape and size of the screen holes on the vibrating screen 142 are designed according to production requirements, so that pellets that meet production requirements can pass through the screen holes and fall into the bottom of the cleaning container 141. The spray assembly 143 is used to spray the pellets in the cleaning container 141 to clean the residual curing liquid and other impurities on the pellets. For example, the spray assembly 143 may include a pure water tank and a spray head connected to each other. The pure water tank is used to store pure water for cleaning, and the spray head can be positioned above the opening of the cleaning container 141. The pure water tank is used to supply pure water to the spray head, and the spray head is used to spray pure water into the cleaning container 141.

[0059] In some embodiments, such as Figure 1 and Figure 5 As shown, there are multiple vibrating screens 142, which are arranged at intervals along the height direction of the washing container 141.

[0060] In this embodiment, by arranging multiple vibrating screens 142 along the height direction inside the cleaning container 141, the multiple vibrating screens 142 can screen the droplets falling into the cleaning container 141 multiple times, so that the droplets that finally fall to the bottom of the cleaning container 141 can meet the production requirements.

[0061] In some embodiments, such as Figure 1 and Figure 5 As shown, the cleaning container 141 is provided with a discharge pipe 144 at the position corresponding to the vibrating screen 142; the screening and cleaning unit 14 also includes a collection bucket 145, which is connected to the discharge pipe 144; the discharge pipe 144 is used to pass the residual droplets on the upper side of the vibrating screen 142 into the collection bucket 145.

[0062] In this embodiment, a discharge pipe 144 is provided on the cleaning container 141. The inlet of the discharge pipe 144 is directly opposite the upper side of the vibrating screen 142. Droplets that do not pass through the screen holes on the vibrating screen 142 enter the discharge pipe 144 under the drive of vibration, move along the discharge pipe 144, and fall into the collection bucket 145, so as to centrally process the droplets that do not meet the production requirements.

[0063] It is understandable that when there are multiple vibrating screens 142, multiple discharge pipes 144 can also be set. Each discharge pipe 144 is set to correspond to each vibrating screen 142, and a collection bucket 145 is set below the outlet end of each discharge pipe 144.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
