Description

Technical Field

[0001] This invention relates to the field of puffing and drying technology, specifically to a feed puffing and drying device and method with intelligent temperature control function. Background Technology

[0002] Feed extrusion drying is a processing technology that uses high temperature and high pressure to expand, cook, and dehydrate feed raw materials. This process uses an extruder to release the pressure of the raw materials instantly under high temperature and high pressure, causing them to expand in volume and loosen in structure. At the same time, it kills harmful microorganisms and improves feed digestibility. Subsequently, the moisture content is reduced by drying equipment, which extends the shelf life and enhances stability. Extruded and dried feed has the advantages of good palatability, high nutrient absorption rate, and convenient storage. It is widely used in the production of aquatic, livestock and poultry and pet feed, effectively improving feed quality and animal growth performance.

[0003] Under current technology, when heating feed, the heating temperature is often manually adjusted based on the quality of the extruded feed. This often damages the feed inside the conveyor, and the temperature cannot be monitored and controlled in real time, which seriously affects production efficiency and quality.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. The heating wire's working efficiency is controlled based on the temperature sensor's detection results to ensure the feed is heated to the required puffing temperature, achieving intelligent temperature control and guaranteeing the quality of feed puffing.

[0015] 2. By setting up a screening component, the particles are classified according to size and degree of drying. Particles of qualified size are air-separated, and particles that have not yet been dried are dried again to ensure that all discharged particles meet the drying requirements and thus guarantee the drying quality of the product.

[0016] 3. The detection component blocks the return of un-dried pellets and uses a distance sensor to detect the distance between itself and the slide plate to determine the frequency at which un-dried pellets accumulate to a certain amount. This allows it to determine whether the working efficiency of the hot air blower is suitable for the current drying requirements. The detection results from the distance sensor are used to control the working efficiency of the hot air blower in real time, further ensuring the drying quality of the feed pellets.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example: Figures 1-4 As shown, the present invention provides a feed puffing and drying device and drying method with intelligent temperature control function. The device comprises a base 1, a support 2 mounted on the base 1, a conveying cylinder 3 mounted on the support 2, a feed hopper 4 mounted on the conveying cylinder 3, a drive motor 5 mounted at one end of the conveying cylinder 3, an installation frame 7 mounted at the bottom end of the conveying cylinder 3 away from the drive motor 5, a heating wire 6 installed inside the conveying cylinder 3, and a pull-out opening 8 on the installation frame 7. The base 1 is detachably mounted with a die opening 9. A back pressure valve 10 is mounted on the mounting frame 7, which is located between the die opening 9 and the conveying cylinder 3. A temperature sensor 12 is mounted on the mounting frame 7, which is located between the back pressure valve 10 and the conveying cylinder 3. A heating controller 11 is mounted on the mounting frame 7, which is electrically connected to the temperature sensor 12 and the heating wire 6. A drying chamber 15 is mounted on the base 1 near the mounting frame 7. A cutting chamber 13 is mounted above the drying chamber 15 and is connected to the mounting frame 7.

[0021] When feed needs to be puffed and dried, feed is poured into the feed hopper 4, and the drive motor 5 and heating wire 6 are started. The drive motor 5 drives the screw of the conveying cylinder 3 to convey and pressurize the feed, and the heating wire 6 heats the feed, forming high-temperature and high-pressure feed in the conveying cylinder 3. When the feed is discharged from the die opening 9 through the back pressure valve 10, the pressure is released, and the feed is puffed. After the puffed feed is cut into the specified size through the cutting chamber 13, it falls into the drying chamber 15 for drying. Before the high-temperature and high-pressure raw material flows through the back pressure valve 10, it will first pass through the temperature sensor 12. The temperature sensor 12 can detect the internal feed temperature in real time and transmit the data back to the heating controller 11. The heating controller 11 will control the heating wire 6 to increase the heating temperature or stop heating according to the temperature requirements.

[0022] A cutting assembly 16, a drying assembly 17, a screening assembly 18, and a detection assembly 19 are arranged on the base 1 on the side away from the drive motor 5; The cutting assembly 16 and the drying assembly 17 cut and dry the extruded feed; The screening component 18 classifies the dried particles according to particle size and degree of dryness; The detection component 19 can control the drying intensity based on the amount of completely dried particles.

[0023] like Figures 1-5 and Figure 9 As shown, the cutting assembly 16 includes a dual-axis motor 1601, a turntable 1602, a connecting rod 1603, a cutting frame 1604, a cutting blade 1605, a sliding rod 1606, and a sliding groove 1607; A dual-axis motor 1601 is installed on the cutting chamber 13. A turntable 1602 is installed on one output shaft of the dual-axis motor 1601. A connecting rod 1603 is eccentrically installed on the turntable 1602. A sliding groove rod 1606 is slidably installed inside the cutting chamber 13. A groove 1607 is opened on the sliding groove rod 1606. The lower end of the connecting rod 1603 is slidably installed in the groove 1607. A cutting frame 1604 is installed inside the cutting chamber 13. A cutting blade 1605 is slidably installed on the cutting frame 1604. The cutting blade 1605 is connected to the sliding groove rod 1606. A discharge port 14 is opened at the lower end of the cutting chamber 13. The cutting chamber 13 is connected to the drying chamber 15 through the discharge port 14.

[0024] Simultaneously with starting the drive motor 5, the dual-axis motor 1601 is also started. The output shaft of the dual-axis motor 1601 drives the turntable 1602 to rotate synchronously. The rotation of the turntable 1602 drives the connecting rod 1603 to rotate synchronously. Since the connecting rod 1603 is eccentrically mounted on the turntable 1602 and is slidably mounted in the slide groove 1607, the connecting rod 1603 drives the cutting blade 1605 to reciprocate vertically through the slide groove rod 1606, thereby cutting the puffed particles.

[0025] like Figures 1-5 and Figures 9-10 As shown, the drying assembly 17 includes a transmission rod 1701, a stabilizer 1702, a first gear 1703, a second gear 1704, a first rotating rod 1705, a second rotating rod 1706, a transmission belt 1707, a drying roller 1708, a drying chamber 1709, an air outlet 1710, and a hot air blower 1711. A transmission rod 1701 is mounted on the output shaft of the dual-shaft motor 1601 on the side away from the turntable 1602. The transmission rod 1701 is connected to the cutting chamber 13 via the stabilizer 1702. The transmission rod 1701 and the stabilizer 1702 are rotatably mounted. A first gear 1703 and a second gear 1704 are rotatably mounted on the drying chamber 15. The first gear 1703 and the second gear 1704 mesh with each other. A first rotating rod 1705 is mounted on the first gear 1703, and a second rotating rod 1706 is mounted on the second gear 1704. Both the first rotating rod 1705 and the second rotating rod 1706 pass through the drying chamber 15 and exit from the drying chamber. The wall of the drying chamber 15 extends away from the first gear 1703 and the second gear 1704. Drying rollers 1708 are installed on both the first rotating rod 1705 and the second rotating rod 1706. The drying rollers 1708 are located inside the drying chamber 15. Several drying chambers 1709 are opened on the drying rollers 1708. The drying chambers 1709 are distributed in a circle on the drying rollers 1708. Several air outlets 1710 are evenly opened in the drying chambers 1709. A hot air blower 1711 is installed on the side of the drying chamber 15 away from the first gear 1703. The output end of the hot air blower 1711 is connected to the air outlet 1710.

[0026] After being cut into pellets, the extruded feed falls into the drying chamber 15 from the feed inlet 14. The operation of the dual-shaft motor 1601 drives the transmission rod 1701 to rotate synchronously. The transmission rod 1701 drives the first gear 1703 to rotate through the transmission belt 1707. The first gear 1703 meshes with the second gear 1704. The first gear 1703 drives the second gear 1704 to rotate in reverse. The rotation of the first gear 1703 and the second gear 1704 drives the corresponding drying rollers 1708 to rotate through the first rotating rod 1705 and the second rotating rod 1706, respectively. The rotation of the two drying rollers 1708 realizes the transfer and conveying of feed pellets in the drying chamber 1709. When the feed pellets are in the drying chamber 1709, the drying hot air provided by the hot air blower 1711 is blown out from the air outlet 1710 to dry the feed pellets. The drying time can be extended in a limited space by using the drying rollers 1708 to transfer and dry the feed pellets. This method of drying and conveying the feed pellets through the drying rollers 1708 can extend the drying time in a limited space. It can ensure the drying quality while enabling the equipment to work continuously, thereby improving production efficiency and drying quality.

[0027] like Figures 1-6 and Figures 9-10 As shown, the screening assembly 18 includes an elevator 1801, a screen separator 1802, a first discharge port 1803, a second discharge port 1804, a third discharge port 1805, a guide frame 1806, a distributor 1807, a discharge rod 1808, a screening outlet 1809, a screening air vent 1810, a qualified material bin 1811, a qualified material inlet 1812, a defective material bin 1813, a defective material inlet 1814, a return material channel 1815, a forced draft fan 1816, a first screening chamber 1817, and a second screening chamber 1818. A hoist 1801 is installed on the drying chamber 15. The input end of the hoist 1801 is connected to the output end of the drying chamber 15. A first screening chamber 1817 is installed on the hoist 1801. A second screening chamber 1818 is installed below the first screening chamber 1817. A screen separator 1802 is installed in the first screening chamber 1817. The input end of the screen separator 1802 is connected to the output end of the hoist 1801. The output end of the screen separator 1802 is connected to a first discharge port 1803, a second discharge port 1804, and a third discharge port 1805, respectively. A flow divider 1807 is installed in the second screening chamber 1818. The flow divider 1807 and the third discharge port 1805 are connected by a guide frame 1806. Two discharge rods 1808 are symmetrically installed in the second screening chamber 1818. The feed rods 1808 are located at both ends of the distributor 1807. The discharge rods 1808 are provided with screening outlets 1809, which are connected to the distributor 1807. Two defective silos 1813 are symmetrically installed in the second screening chamber 1818. The two defective silos 1813 are connected by a qualified silo 1811. The defective silos 1813 are provided with defective material inlets 1814, and the qualified silos 1811 are provided with qualified material inlets 1812. The elevator 1801 is provided with a return channel 1815, which is located below the defective material inlet 1814. A screening air vent 1810 is installed below the discharge rods 1808. A powerful blower 1816 is installed in the second screening chamber 1818, and the output end of the powerful blower 1816 is connected to the screening air vent 1810.

[0028] The dried feed pellets are lifted by elevator 1801 to the top of screener 1802 and fall into the inlet of screener 1802. After being screened by screener 1802, oversized and undersized pellets are discharged from the first discharge port 1803 and the second discharge port 1804, respectively. Pellets of the correct size flow into distributor 1807 from the third discharge port 1805. Distributor 1807 is shaped with a high center and low ends. The pellets flow to the discharge bars 1808 on both sides and exit from the screening outlet. 1809 Falls downwards. After the pellets fall from the screening outlet, the air from the screening vent 1810 will exert a lateral thrust on the feed pellets, causing them to move in a curved path. The qualified dried pellets will eventually fall into the qualified feed hopper 1811 and be discharged from the qualified feed inlet 1812. The undried pellets, due to their larger mass, have a shorter lateral movement distance and will fall into the defective feed hopper 1813 and fall from the defective feed inlet 1814 onto the return channel 1815, rolling back into the drying chamber 15 for further drying.

[0029] The width of the screening outlet 1809 is greater than the width of a single product particle, but less than twice the width of a single particle.

[0030] When feed pellets fall downwards, an excessively large screening outlet 1809 may cause pairs of pellets to appear on the same horizontal plane, generating horizontal forces on each other and affecting the screening results. A reasonable screening outlet 1809 size ensures that only one pellet falls downwards at a time, avoiding horizontal compression and guaranteeing screening efficiency.

[0031] like Figures 1-8 and Figure 10 As shown, the detection component 19 includes a mounting plate 1901, an electric telescopic rod 1902, a return material notch 1903, a return material baffle 1904, a pressure sensor 1905, a linkage plate 1906, a linkage rod 1907, a guide rail 1908, a mating hole 1909, a trigger 1910, a work box 1911, an air pump 1912, a slide plate 1913, an air chamber 1914, a return spring 1915, an exhaust valve 1916, a distance sensor 1917, and an air pump switch 1918. An installation plate 1901 is mounted on the elevator 1801. An electric telescopic rod 1902 is mounted on the installation plate 1901. A return material notch 1903 is provided on the return material channel 1815. A return material baffle 1904 is slidably mounted on the return material notch 1903 and is connected to the end of the electric telescopic rod 1902. A linkage plate 1906 is mounted on the electric telescopic rod 1902. A mating hole 1909 is provided on the linkage plate 1906. A linkage rod 1907 is rotatably mounted on the installation plate 1901. A guide rail 1908 is provided on the linkage rod 1907 and mates with the mating hole 1909. A trigger 1910 is mounted on the linkage rod 1907. A working box 1911 is mounted on board 1901. An air pump 1912 and an air pump switch 1918 are mounted on the working box 1911. The air pump switch 1918 is mounted on the side near the trigger 1910. A sliding plate 1913 is slidably mounted inside the working box 1911. The sliding plate 1913 is connected to one wall of the working box 1911 by a return spring 1915. The sliding plate 1913 and the wall away from the return spring 1915 form an air chamber 1914. The air chamber 1914 is connected to the output end of the air pump 1912. An exhaust valve 1916 is mounted on the air chamber 1914. A distance sensor 1917 is mounted on the wall inside the working box 1911 where the return spring 1915 is mounted.

[0032] Air pump switch 1918 is electrically connected to air pump 1912, air pump 1912 is electrically connected to exhaust valve 1916, and distance sensor 1917 is electrically connected to hot air blower 1711.

[0033] When feed pellets required for drying flow back from the return channel 1815, they are blocked by the return baffle 1904. When the pressure sensor 1905 detects a certain amount of accumulated return pellets, it sends an electrical signal to control the electric telescopic rod 1902 to retract and then return to its original position after a delay, allowing the accumulated return pellets to flow back into the drying chamber 15. When the electric telescopic rod 1902 retracts, it drives the linkage plate 1906 to move synchronously. Due to the limiting effect of the guide rail 1908 on the mating hole 1909, when the linkage plate 1906 moves, it drives the linkage rod 1904 to move synchronously. 07. A full rotation of the linkage 1907 will cause the trigger 1910 to open the air pump switch 1918. The air pump switch 1918 controls the air pump 1912 to supply air into the air chamber 1914. At this time, the exhaust valve 1916 is closed, and the air pressure in the air chamber 1914 increases, pushing the slide plate 1913 towards the distance sensor 1917. The distance sensor 1917 will record the closest distance between the slide plate 1913 and the distance sensor 1917 each time. When the electric telescopic rod 1902 extends and resets, the trigger 1910... The air pump switch 1918 will be turned off, and the air pump 1912 will stop supplying air to the air chamber 1914. The air pump 1912 will send an electrical signal to control the exhaust valve 1916 to open. The return spring 1915 will push the slide plate 1913 to return to its original position due to its elastic potential energy. When the undried particles are within the normal range, when the slide plate 1913 returns to its original position, the particles accumulated on the return baffle 1904 will reach the preset amount again, and the air pump 1912 will be controlled to supply air to the air chamber 1914 again, repeating the above air intake and exhaust process. When the amount of undried particles is large, the return material... When the particles accumulated on the baffle 1904 reach the preset value in advance, before the gas in the air chamber 1914 is completely discharged and the slide plate 1913 has returned to its initial position, the air pump 1912 will pump air into the air chamber again. At this time, the slide plate 1913 will be pushed to a position closer to the distance sensor 1917 than in the previous process. The distance sensor 1917 will send an electrical signal based on the comparison with the previous recorded result, controlling the hot air blower 1711 to increase its power, improve drying efficiency, reduce the amount of unacceptable dried particles, and ensure the drying quality of the product.

[0034] The drying method of the feed puffing and drying device with intelligent temperature control function provided in this application includes the following steps: Step 1: Pour the raw material into the feed hopper 4. The raw material is extruded and conveyed by the screw of the conveying cylinder 3 and heated by the heating wire 6 to form a high temperature and high pressure raw material. After passing through the back pressure valve 10, it is discharged from the die 9. After the pressure is released, the feed is expanded. Step 2: The feed is processed through the extrusion port, where it is cut into pellets of a specified size by the cutting blade 1605. The product pellets fall into the drying chamber 1709 and are dried under the action of hot air. Step 3: Before the high-temperature and high-pressure raw material flows through the back pressure valve 10, it will first pass through the temperature sensor 12. The temperature sensor 12 can detect the internal feed temperature in real time and transmit the data back to the heating controller 11. The heating controller 11 will control the heating wire 6 to increase the heating temperature or stop heating according to the temperature requirements.

[0035] The working principle of this invention is as follows: the temperature sensor 12 detects the temperature of the high-temperature and high-pressure feed that is about to be puffed in real time, and controls the working efficiency of the heating wire 6 according to the detection results to ensure that the feed is heated to the puffing requirements, thereby achieving intelligent temperature control and ensuring the quality of feed puffing.

[0036] By setting up the drying roller 1708, the expanded particles are transferred and dried, which can extend the drying time in a limited space, ensure the drying quality while enabling the equipment to work continuously, and improve production efficiency and drying quality.

[0037] By setting up a screening component 18, the particles are classified according to size and degree of drying. Particles of qualified size are air-separated, and particles that have not yet been dried are dried again to ensure that all discharged particles meet the drying requirements and thus guarantee the drying quality of the product.

[0038] The detection component 19 blocks the return of un-dried pellets and uses the distance sensor 1917 to detect the distance between itself and the slide plate 1913 to determine the frequency at which un-dried pellets accumulate to a certain amount. This allows it to determine whether the working efficiency of the hot air blower 1711 is suitable for the current drying requirements. The detection results from the distance sensor 1917 are used to control the working efficiency of the hot air blower 1711 in real time, further ensuring the drying quality of the feed pellets.

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
