Description

Technical Field

[0001] This invention relates to the field of food processing technology, and in particular to a high-efficiency and energy-saving combined device for food processing raw material pretreatment. Background Technology

[0002] In the food processing industry, raw material pretreatment is a crucial step, with dehydration being particularly critical. The main purpose of dehydration is to reduce the water activity of raw materials, inhibit microbial growth, extend shelf life, and facilitate subsequent transportation, storage, and processing (such as crushing, mixing, and packaging). Traditional dehydration methods include natural sun-drying, hot air drying, vacuum freeze-drying, and mechanical pressing or centrifugal dehydration.

[0003] However, these methods each have their limitations: natural air drying is inefficient, highly susceptible to weather conditions, and difficult to control hygiene; hot air drying alone is energy-intensive and inefficient when the initial moisture content of the material is high, easily leading to surface crusting and difficulty in evaporating internal moisture; while mechanical centrifugation alone can quickly remove surface and some internal moisture, it has limited effectiveness in removing bound water within cells, and high-speed, long-term dehydration can damage the structure of brittle materials such as fruits and vegetables, affecting the quality of the finished product. Therefore, how to combine the advantages of different dehydration technologies to achieve an efficient, energy-saving dehydration process that protects material quality is an urgent problem to be solved in this field. Summary of the Invention

[0004] The purpose of this invention is to provide a highly efficient and energy-saving combined device for food processing raw material pretreatment to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-efficiency and energy-saving food processing raw material pretreatment combined device includes a dehydration outer cylinder, a base plate, a centrifugal tray mechanism, a water collection assembly, a central controller, and a hot air furnace. The dehydration outer cylinder is fixed to the base plate by multiple legs. A discharge port and multiple water outlets are located on the outer wall of the dehydration outer cylinder near the bottom wall. The water collection assembly is located on the outside of the dehydration outer cylinder and is used to receive water flowing out through the water outlets and to measure its weight. The centrifugal tray mechanism includes a centrifugal disc, a centrifugal shaft, a top-pull assembly, and multiple circular baffles. The centrifugal disc is rotatably positioned at the opening in the center of the bottom wall of the dehydration outer cylinder. The multiple circular baffles are evenly distributed along the edge of the centrifugal disc and can move vertically relative to the centrifugal disc, with their lower ends extending to the lower side of the dehydration outer cylinder. The top-pull assembly is located below the dehydration outer cylinder. Multiple circular baffles are connected at their bottom ends and drive them to move vertically. One end of the centrifugal shaft is fixedly connected to the center of the bottom of the centrifugal disc, and the other end is connected to the dewatering motor mounted on the base plate. A jet cone assembly is provided in the center of the centrifugal disc, and the jet cone assembly and multiple circular baffles form a centrifugal dewatering chamber for accommodating materials. The interior of the jet cone assembly is connected to the centrifugal shaft, and the hot air furnace is connected to the centrifugal shaft and sends hot air into the centrifugal shaft. The main controller is electrically connected to the water manifold assembly, the dewatering motor, and the hot air furnace. The water manifold assembly transmits the sensed moisture weight data to the main controller, and the main controller adjusts the dewatering motor speed and the hot air furnace power in real time based on the data received from the water manifold assembly. A discharge channel for discharging the dewatered material is also provided on the outer wall of the dewatering outer cylinder.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0008] In one alternative embodiment: the top-pull assembly includes a lower top-pull ring plate, a connecting ring, a collar frame, and at least one lifting cylinder. The lower top-pull ring plate is located on the lower side of the dehydration outer cylinder and is fixedly connected to the bottom of multiple circular stop rods. The collar frame can be vertically slidably sleeved on the outside of the centrifugal shaft, and its outer wall is fixedly connected to the lower top-pull ring plate through multiple support arms. The connecting ring is rotatably disposed on the lower end face of the lower top-pull ring plate, with the centrifugal shaft axis as its rotation center. The lifting cylinder is disposed on the dehydration outer cylinder, and its top is connected to the connecting ring.

[0009] In one alternative: the inner bottom surface of the dehydration outer cylinder is conical, and the edge of the centrifuge disc is provided with multiple circumferentially evenly distributed scraper strips, which are in close contact with the inner bottom surface of the dehydration outer cylinder.

[0010] In one alternative: a sealing assembly is provided at the discharge port. The lower end of the sealing assembly passes through the bottom wall of the dewatering outer cylinder and can be connected to the lower top pull ring plate. When the lower top pull ring plate approaches the bottom wall of the dewatering outer cylinder, it can act on the lower end of the sealing assembly, which moves upward to the inside of the discharge port to close the discharge port. When the lower top pull ring plate moves downward, the sealing assembly automatically moves downward to open the discharge port.

[0011] In one alternative embodiment: the sealing assembly includes a sealing plate and a radial extension roller. The sealing plate extends from the bottom of the dewatering outer cylinder into the discharge port to seal the discharge port. The bottom of the sealing plate has at least one lower protrusion with an opening spring on it. One end of the opening spring is connected to the bottom wall of the dewatering outer cylinder. One end of the radial extension roller is rotatably connected to the side wall of the sealing plate near the bottom, and the other end extends to the edge of the lower top pull ring plate and is located on the upper side.

[0012] In one alternative: the water collection assembly includes an annular collection trough and a drain pipe. The annular collection trough surrounds the outer wall of the dewatering outer cylinder and its interior communicates with the interior of the dewatering outer cylinder through multiple water outlet holes. The drain pipe is located on the outer wall of the annular collection trough and is equipped with a water volume detector.

[0013] In one alternative: the hot air furnace has a gas guide pipe at its outlet end, and a venting sleeve is provided at the end of the gas guide pipe away from the hot air furnace. The venting sleeve is rotatably mounted on the centrifugal shaft, and the gas guide pipe is connected to the inside of the centrifugal shaft through the venting sleeve. The jet cone assembly includes a jet cone and an electric heating rod. The jet cone assembly is located on the upper end face of the centrifugal disk, and multiple air holes are distributed on its conical surface. The electric heating rod is located inside the jet cone and is provided with an electric contact support.

[0014] In one alternative: a feed hopper is also provided at the port of the dewatering outer cylinder, the bottom opening of the feed hopper is provided, and its outer edge is fixedly connected to the edge of the port of the dewatering outer cylinder. Multiple levers extending into the centrifugal dewatering chamber are provided on the lower surface of the feed hopper.

[0015] By adopting the above technical solution, the present invention has the following beneficial effects:

[0016] This invention combines centrifugal dehydration with hot air drying. First, it utilizes mechanical centrifugal force to efficiently remove most of the free water from the material, significantly reducing the load and energy consumption of subsequent hot drying, thus achieving energy savings. Simultaneously, the combined treatment method demonstrates significantly higher overall dehydration efficiency than a single method. The central controller intelligently adjusts the dehydration motor speed and hot air furnace power based on real-time measured water removal volume. High-speed centrifugation is used during the initial high-moisture stage of dehydration. Once a certain dehydration rate is achieved, it automatically switches to or superimposes gentle hot air drying, avoiding excessive compression and structural damage to the material caused by using high centrifugal force during the low-moisture stage, effectively protecting the original shape and quality of the material. The water flow assembly monitors the dehydration volume in real time, and the central controller automatically adjusts the equipment operating parameters based on this data, achieving closed-loop control of the dehydration process, reducing manual intervention, and ensuring the consistency and stability of the processing. The unique circular baffle design acts as a barrier during dehydration, and after dehydration, it can be lowered by the top-pull assembly, allowing the material to be smoothly discharged from the outlet under centrifugal force, achieving effective separation of material and moisture and continuous operation.

Detailed Implementation

[0027] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. 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.

[0028] The left, right, up, and down positions of the various components shown in the attached diagram are just one arrangement method; the specific positions should be set according to specific needs.

[0029] In one embodiment, such as Figures 1-5As shown, a high-efficiency and energy-saving food processing raw material pretreatment combined device includes a dehydration outer cylinder 100, a base plate 200, a centrifugal tray mechanism 300, a water collection assembly 400, a central controller, and a hot air furnace 800. The dehydration outer cylinder 100 is fixed to the base plate 200 by multiple support legs. A discharge port 120 and multiple water outlets 110 are provided on the outer wall of the dehydration outer cylinder 100 near the bottom wall. The water collection assembly 400 is located on the outside of the dehydration outer cylinder 100 and is used to receive the water flowing out through the water outlets 110. The centrifugal tray mechanism 300 includes a centrifugal tray 310, a centrifugal shaft 320, a top-pull assembly, and multiple circular baffles 340. The centrifugal tray 310 is rotatably positioned at the opening at the center of the bottom wall of the dewatering outer cylinder 100. The multiple circular baffles 340 are evenly distributed along the edge of the centrifugal tray 310 and can move vertically relative to the centrifugal tray 310. Their lower ends extend to the lower side of the dewatering outer cylinder 100. The top-pull assembly is located below the dewatering outer cylinder 100. The top-pull assembly is connected to the bottom ends of multiple circular baffles 340, driving them to move vertically; one end of the centrifugal shaft 320 is fixedly connected to the bottom center of the centrifugal disc 310, and the other end is connected to the dewatering motor 700 mounted on the base plate 200; a jet cone assembly 600 is provided at the center of the centrifugal disc 310, forming a centrifugal dewatering chamber for accommodating materials between the jet cone assembly 600 and the multiple circular baffles 340; the interior of the jet cone assembly 600 communicates with the centrifugal shaft 320, and the hot air furnace 80... 0 is connected to the centrifugal shaft 320 and sends hot air into the centrifugal shaft 320; the main controller is electrically connected to the water manifold 400, the dewatering motor 700 and the hot air furnace 800. The water manifold 400 transmits the sensed moisture weight data to the main controller. The main controller adjusts the speed of the dewatering motor 700 and the power of the hot air furnace 800 in real time according to the data received from the water manifold 400; the outer wall of the dewatering outer cylinder 100 is also provided with a discharge channel 500 for discharging the dewatered material.

[0030] In this embodiment of the invention, initially, the port connecting the discharge channel 500 to the dewatering outer cylinder 100 is closed. The material to be dewatered is placed in the centrifugal dewatering chamber formed by the jet cone assembly 600 and multiple circular baffles 340. In the initial stage of dewatering, the dewatering motor 700 drives the centrifugal tray mechanism 300 to rotate at high speed. The material on the centrifugal disc 310 rotates at high speed along with the centrifugal tray mechanism 300 and is blocked by the circular baffles 340 in the centrifugal dewatering chamber. Under centrifugal action, the water in the material gradually separates from the material. The material is then swung into the space between the circular baffle 340 and the dewatering outer cylinder 100. Water flows into the water collection assembly 400 through the outlet 110, where it is weighed and guided out. The water data measured by the water collection assembly 400 is transmitted to the central controller. Based on the received data, the central controller determines the dewatering rate of the material and adjusts the speed of the dewatering motor 700 accordingly. This is to prevent the material from maintaining a high speed when the dewatering rate is high, as this could cause excessive centrifugal force and damage to the material. This process causes significant deformation and damage. During the middle stage of dehydration, when the material's dehydration rate reaches the set target, the water manifold assembly 400 starts the hot air furnace 800. The hot air furnace 800 introduces hot airflow into the jet cone assembly 600 through the centrifugal shaft 320. The hot airflow is sprayed onto the material through the surface of the jet cone assembly 600. During rotation, the material exchanges heat with the hot airflow, effectively evaporating any residual moisture and improving the material's dehydration efficiency. Furthermore, the initial dehydration using mechanical centrifugation results in relatively high dehydration efficiency and can play a significant role in... Energy saving effect: subsequent use of a combination of centrifugal and thermal drying to improve dehydration effect; after dehydration, the top pull assembly drives multiple circular baffles 340 to move downwards until the top of the circular baffles 340 is flush with the upper surface of the centrifugal disc 310. At this time, the discharge port 120 is in the open state. The rotation of the centrifugal disc 310 causes the material to gradually detach from its surface and move towards the discharge port 120. The material enters the discharge channel 500 through the discharge port 120 and is discharged, which can effectively achieve the separation of material and water and improve dehydration efficiency.

[0031] In one embodiment, such as Figures 1-5As shown, the top-pull assembly includes a lower top-pull ring plate 330, a connecting ring 360, a collar frame 370, and at least one lifting cylinder 380. The lower top-pull ring plate 330 is located on the lower side of the dewatering outer cylinder 100 and is fixedly connected to the bottom of multiple circular stop rods 340. The collar frame 370 can be vertically slidably sleeved on the outside of the centrifugal shaft 320, and its outer wall is fixedly connected to the lower top-pull ring plate 330 through multiple support arms. The connecting ring 360 is rotatably disposed on the lower end face of the lower top-pull ring plate 330, with the axis of the centrifugal shaft 320 as its rotation center. The lifting cylinder 380 is disposed on the dewatering outer cylinder 100. The top of the lower top pull ring plate 330 is connected to the connecting ring 360. In this embodiment of the invention, the lower top pull ring plate 330 rotates with the centrifugal shaft 320 and the centrifugal disc 310 due to the connection between the circular stop bar 340 and the collar frame 370. Due to the rotational cooperation between the lower top pull ring plate 330 and the connecting ring 360, the connecting ring 360 and the lifting cylinder 380 remain in a stable state and there will be no interference. The lifting cylinder 380 drives the lower top pull ring plate 330 to rise and fall through its own extension and retraction, so as to realize the vertical movement of the circular stop bar 340, so as to form a retractable enclosure, thereby performing centrifugal dehydration and discharging materials.

[0032] In one embodiment, such as Figures 1-5 As shown, the inner bottom surface of the dehydration outer cylinder 100 is conical, and the edge of the centrifugal disc 310 is provided with multiple circumferentially evenly distributed scraper bars 350, which are in close contact with the inner bottom surface of the dehydration outer cylinder 100. In this embodiment of the invention, during centrifugal dehydration, the scraper bars 350 rotate with the centrifugal disc 310, which can scrape off the dehydrated liquid from the bottom surface of the inner wall of the dehydration outer cylinder 100, allowing it to enter the outlet hole 110 along the side. The shape of the bottom surface of the inner wall of the dehydration outer cylinder 100 can guide the dehydrated liquid to flow towards the edge of the bottom wall of the dehydration outer cylinder 100, ensuring that the dehydrated liquid is fully discharged. When the material is discharged, the scraper bars 350 also move the material to rotate inside the dehydration outer cylinder 100, and under the guidance of the bottom wall of the dehydration outer cylinder 100 and the centrifugal action of rotation, the material can be discharged from the outlet 120.

[0033] In one embodiment, such as Figures 1-6As shown, a capping assembly 900 is provided at the discharge port 120. The lower end of the capping assembly 900 passes through the bottom wall of the dewatering outer cylinder 100 and can be connected to the lower top pull ring plate 330. When the lower top pull ring plate 330 approaches the bottom wall of the dewatering outer cylinder 100, it can act on the lower end of the capping assembly 900, which moves upward into the discharge port 120 to close the discharge port 120. When the lower top pull ring plate 330 moves downward, the capping assembly 900 automatically moves downward to open the discharge port 120. In this embodiment of the invention, in the initial state, the lifting cylinder 380 extends and pushes the lower top pull ring plate 330 upward. The circular baffle 340 moves upward along with the lower pull ring plate 330, and its top moves close to the port of the dewatering outer cylinder 100 to form a barrier. The lower pull ring plate 330 can act on the lower end of the capping assembly 900 to move it upward. The top of the capping assembly 900 is inside the discharge port 120 to close the discharge port 120. Therefore, during material dewatering, the dewatering liquid generated by centrifugation will not be discharged through the discharge port 120. When the circular baffle 340 moves downward along with the lower pull ring plate 330, the capping assembly 900 automatically moves downward and opens the discharge port 120 to discharge the material.

[0034] In one embodiment, such as Figures 1-6 As shown, the sealing assembly 900 includes a sealing plate 910 and a radial extension roller 940. The sealing plate 910 extends from the bottom of the dewatering outer cylinder 100 into the discharge port 120 to seal the discharge port 120. The bottom of the sealing plate 910 has at least one lower protrusion 920, and an opening spring 930 is provided on the lower protrusion 920. One end of the opening spring 930 is connected to the bottom wall of the dewatering outer cylinder 100. One end of the radial extension roller 940 is rotatably connected to the side wall of the sealing plate 910 near the bottom, and the other end extends to the edge of the lower top pull ring plate 330 and is in an upper position. In this embodiment of the invention, the initial state is... When the material is discharged, due to the elastic force of the opening spring 930, the upper end of the sealing plate 910 is flush with the bottom surface inside the dewatering outer cylinder 100. At this time, the discharge port 120 is in the open state. When the material is fed in and the material is dewatered, the lower top pull ring plate 330 moves upward, and its edge or the end of the radial extension roller 940 away from the sealing plate 910 contacts and drives it to move upward. The sealing plate 910 gradually extends into the discharge port 120 and closes the discharge port 120 to prevent the dewatering liquid generated by dewatering from being discharged through the discharge port 120, which would affect the subsequent material discharge and the accuracy of the water weight measurement by the water collection assembly 400.

[0035] In one embodiment, such as Figures 1-3As shown, the water collection assembly 400 includes an annular collection trough 410 and a drain pipe 420. The annular collection trough 410 surrounds the outer wall of the dewatering outer cylinder 100, and its interior is connected to the interior of the dewatering outer cylinder 100 through multiple water outlet holes 110. The drain pipe 420 is located on the outer wall of the annular collection trough 410, and a water volume detector 430 is installed on it. In this embodiment of the invention, the dewatering liquid inside the dewatering outer cylinder 100 flows into the annular collection trough 410 through multiple water outlet holes 110, and is then discharged through the drain pipe 420. When the dewatering liquid flows from the annular collection trough 410 to the drain pipe 420, it passes through the water volume detector 430. The water volume detector 430 is used to detect the flow rate of the dewatering liquid in order to determine the weight of the water removed from the material.

[0036] In one embodiment, such as Figure 1 , Figure 3 , Figure 4 and Figure 7 As shown, the hot blast stove 800 has a gas guide pipe 810 at its outlet end. A vent sleeve 820 is provided at the end of the gas guide pipe 810 away from the hot blast stove 800. The vent sleeve 820 is rotatably mounted on the centrifugal shaft 320. The gas guide pipe 810 is connected to the interior of the centrifugal shaft 320 through the vent sleeve 820. The jet cone assembly 600 includes a jet cone 610 and an electric heating rod 640. The jet cone assembly 600 is located on the upper surface of the centrifugal disk 310, and its cone surface is distributed with… There are multiple air holes 620, and an electric heating rod 640 is disposed inside the jet cone 610, on which an electric contact support 630 is provided. In this embodiment of the invention, the hot airflow enters the jet cone 610 through the centrifugal shaft 320. The electric heating rod 640 works and energizes the electric contact support 630. After being energized, the electric contact support 630 heats up and can further heat the airflow. The heated airflow can be sprayed outward through the air holes 620 so that the material is heated evenly and the drying and dehydration efficiency is improved.

[0037] In one embodiment, such as Figure 1 and Figure 7 As shown, a feed hopper 130 is also provided at the port of the dewatering outer cylinder 100. The bottom opening of the feed hopper 130 is provided, and its outer edge is fixedly connected to the edge of the port of the dewatering outer cylinder 100. A plurality of levers 140 extending into the centrifugal dewatering chamber are provided on the lower surface of the feed hopper 130. In this embodiment of the invention, when the material rotates with the centrifugal disc 310, the levers 140 remain stable and can turn the material so that the material can fully contact the hot airflow.

[0038] The above-described embodiments of the invention provide a high-efficiency and energy-saving food processing raw material pretreatment combined device, the working principle of which is as follows:

[0039] 1. Initial Preparation and Material Feeding: In the initial state of the device, the lifting cylinder 380 is in the extended state, pushing the lower top pull ring plate 330 upward, which in turn drives multiple circular baffles 340 to move upward to the highest position. At this time, the top of the circular baffles 340 and the upper surface of the centrifugal disc 310 together form a complete enclosure, constituting the centrifugal dewatering chamber.

[0040] At the same time, when the lower top pull ring plate 330 moves upward, its edge will act on the radial extension roller 940 of the capping assembly 900, overcome the elastic force of the opening spring 930, and push the sealing plate 910 upward into the discharge port 120, thereby sealing the discharge port 120 and preventing liquid leakage during the subsequent dehydration process.

[0041] The food raw materials to be processed are fed into the centrifugal dehydration chamber formed by the jet cone assembly 600 and the circular baffle 340 through the feed hopper 130 at the port. The lever 140 on the lower surface of the feed hopper 130 extends into the dehydration chamber.

[0042] 2. Centrifugal dehydration stage, initial stage of dehydration:

[0043] Centrifugation Start: The main controller starts the dewatering motor 700, which drives the centrifuge shaft 320 to rotate at high speed, thereby causing the entire centrifuge tray mechanism 300, including the centrifuge tray 310, scraper bar 350, and circular baffle 340 connected by the collar frame 370, to rotate together. Under the action of centrifugal force, the material is thrown to the outside of the dewatering chamber and blocked by the circular baffle 340.

[0044] Moisture separation and monitoring: Under the strong centrifugal force, free water in the material is rapidly ejected, passing through the gaps between the circular baffles 340 and impacting the inner wall of the dewatering outer cylinder 100. Because the bottom of the dewatering outer cylinder 100 is conical, the water flows along the inclined surface to the bottom of the cylinder wall and flows through the outlet hole 110 into the external annular collecting trough 410. The collected water is finally discharged through the drain pipe 420 and flows through the water volume detector 430 on the drain pipe 420.

[0045] Intelligent control: The water level detector 430 monitors and calculates the weight of the removed water in real time, transmitting the data to the central controller. The central controller calculates the real-time material dehydration rate based on a preset algorithm, such as the relationship between dehydration volume and time. When the dehydration rate reaches a certain level, indicating that most of the free water has been removed, the central controller will instruct the dehydration motor 700 to reduce its speed and enter a gentler dehydration mode to achieve energy saving and protect product quality.

[0046] 3. Mid-stage of dehydration in the hot air drying phase:

[0047] Start hot air: When the central controller determines that the centrifugal dehydration rate of the material has reached the preset target, for example, after the surface water has been basically removed, it will automatically start the hot air furnace 800.

[0048] Hot air delivery and heating: The hot airflow generated by the hot air furnace 800 is sent into the interior of the high-speed rotating centrifugal shaft 320 through the air guide pipe 810 and the air vent sleeve 820. The hot airflow enters the interior of the jet cone 610 along the channel in the center of the centrifugal shaft 320. The electric heating rod 640 and its electric contact support 630 installed in the jet cone 610 are energized to perform secondary heating on the airflow, ensuring uniform and efficient hot air temperature.

[0049] Convection drying: Heated hot air is evenly sprayed onto the rotating material through multiple air holes 620 on the cone surface of the jet cone 610. Simultaneously, the lever 140 below the stationary feed hopper 130 continuously agitates the rotating material, ensuring that all parts are in full contact with the hot air for efficient heat exchange, evaporating any remaining bound water inside the material. This stage combines the advantages of mechanical centrifugal force to remove moisture and hot air convection to evaporate moisture, significantly improving dehydration efficiency and depth.

[0050] 4. Late stage of dehydration during unloading:

[0051] Open the discharge port 120: After the dehydration and drying process is completed, the main controller controls the lifting cylinder 380 to retract, pulling the lower top pull ring plate 330 downward.

[0052] The downward movement of the lower top pull ring plate 330 causes the circular stop bar 340 to descend, so that its top is flush with or lower than the upper surface of the centrifugal disc 310, thus removing the confinement of the material.

[0053] Simultaneously, as the lower top pull ring plate 330 moves downward, the force on the radial extension roller 940 of the cover assembly 900 disappears. Under the restoring force of the opening spring 930, the sealing plate 910 exits from the discharge port 120, opening the discharge channel 500.

[0054] Material discharge: The dewatering motor 700 continues to rotate or rotate at a low speed, and the scraper bars 350 on the centrifugal disc 310 rotate with it, pushing the material against the conical bottom wall of the dewatering outer cylinder 100. Under the centrifugal force and the pushing action of the scraper bars 350, the dried material moves along the inclined surface to the opened discharge port 120, falls into the discharge channel 500, and is finally discharged from the device, completing the entire pretreatment process.

[0055] This device intelligently coordinates the centrifugal dehydration and hot air drying stages through a central controller, and uses feedback data from the water manifold component 400 to adjust motor speed and hot air power in real time, achieving efficient, energy-saving, and continuous operation that protects material quality.
