Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a continuous fryer with a slag removal function. Background Technology

[0002] Continuous fryers are commonly used continuous food processing equipment in the food industry. They are suitable for the continuous production of meat, seafood, vegetables, pasta, and other products. They greatly reduce the oxidation of edible oil, extend the service life of the oil, and improve the safety of the equipment. During the frying process, the food itself and the coating powder will produce oil residue / debris in the oil. If not cleaned in time, it will affect the oil quality and reduce the utilization rate of the oil. Suspended oil residue or debris can be filtered out through oil circulation. Floating oil residue or debris can flow out of the fryer with the material under the action of the conveyor belt. However, oil residue with a higher density will sink to the bottom of the oil and needs to be collected and cleaned.

[0003] Current continuous fryers lack a slag removal function, making it difficult to clean and collect the oil slag that sinks to the bottom of the fryer. Currently, the usual method for cleaning the oil slag is to stop the continuous fryer, drain the oil, and then remove the slag. This method not only severely affects production efficiency but also causes the oil slag to remain in the oil for an extended period, affecting the oil quality. Furthermore, existing continuous fryers also have the drawback of making it inconvenient to clean their internal conveying mechanisms. Summary of the Invention

[0004] This invention addresses the problems of existing continuous fryer machines lacking slag removal functionality, making it difficult to clean and collect slag that has sunk to the bottom of the continuous fryer, and hindering the cleaning of the conveying mechanism. It provides a continuous fryer with a slag removal function, facilitating the collection and cleaning of slag that has sunk to the bottom of the oil. The continuous fryer can clean the slag without stopping the machine and discharge the collected slag. It can ensure the production capacity of the continuous fryer without affecting normal production and mitigate changes in oil quality. Simultaneously, its internal conveying mechanism can move vertically, facilitating cleaning and maintenance of the conveying mechanism.

[0005] To achieve the above objectives, the technical solution of this utility model is: a continuous fryer with a slag removal function, comprising an outer frame, an oil tank inside the outer frame, and a top mesh belt, a bottom mesh belt, and a slag scraping mesh belt arranged sequentially from top to bottom inside the oil tank. A lifting frame connected to the top mesh belt and the bottom mesh belt is also installed inside the oil tank. Multiple scrapers are spaced apart on the top mesh belt. Screw jacks connected to the lifting frame are installed on both sides of the outer frame. The oil tank stores oil, the top mesh belt and the bottom mesh belt convey materials entering the oil tank, and the slag scraping mesh belt conveys oil slag that has sunk to the bottom. The screw jacks drive the lifting frame to move up and down, thus enabling the lifting frame to move the top mesh belt, the bottom mesh belt, and the slag scraping mesh belt up and down, facilitating cleaning and maintenance of the top mesh belt, the bottom mesh belt, and the slag scraping mesh belt.

[0006] The outer frame also includes a slag discharge shell connected to the oil tank, with the discharge end of the slag scraping mesh belt located above the slag discharge shell. One end of the slag discharge shell is inclined upwards and extends beyond the outer frame. A slag scraping mechanism is installed inside the slag discharge shell, comprising a scraping bracket, a scraping assembly, and a drive assembly. The scraping bracket matches the slag discharge shell, and the drive assembly is connected to the scraping assembly. The slag discharge shell collects the oil slag conveyed by the scraping mesh belt and facilitates the scraping mechanism's transport and discharge of the collected oil slag from the oil tank. The scraping mechanism discharges the oil slag from the slag discharge shell, while the scraping bracket houses the scraping assembly and drive assembly. The drive assembly drives the scraping assembly to operate inside the slag discharge shell, scraping out the oil slag.

[0007] Furthermore, a feed hood and a discharge hood are respectively provided at both ends of the oil tank, and a support frame is provided on the top of the lifting frame, which is connected to the screw jack; the top of the outer frame is provided with an upper cover connected to the support frame, and a chimney is provided on the upper cover. The feed hood facilitates the conveying of materials into the oil tank, the discharge hood facilitates the discharge of materials from the oil tank, the support frame supports the upper cover, and is also connected to the screw jack so that the screw jack can drive the lifting frame to move up and down.

[0008] Furthermore, a transmission mechanism is provided at the bottom of the outer frame. The transmission mechanism includes a motor, two commutators, and a connecting rod. The output end of the motor is connected to the input end of one of the commutators. The two commutators are connected by a connecting rod. The output end of the commutator is connected to a transmission rod, which is connected to the screw jack. The screw jack can be driven to operate through the transmission mechanism, so that the screw jack can drive the upper cover, the mesh belt, the lower mesh belt, and the slag scraper to move up and down, thereby facilitating cleaning and maintenance.

[0009] Furthermore, the lifting frame is equipped with a power mechanism for the slag scraping mesh belt drive. The power mechanism includes a second geared motor, a slag scraping drive shaft, and two slag scraping driven shafts. The slag scraping drive shaft and the two slag scraping driven shafts are rotatably connected to the lifting frame. The output end of the second geared motor is connected to the slag scraping drive shaft. The slag scraping drive shaft is connected to one of the slag scraping driven shafts through a sprocket and chain structure. The slag scraping mesh belt is sleeved on the two slag scraping driven shafts. Through the action of the power mechanism, the slag scraping mesh belt is able to transport oil sludge that has sunk to the bottom of the oil tank, thereby achieving the effect of transporting the oil sludge that has sunk to the bottom of the oil tank to the slag discharge shell.

[0010] Furthermore, the slag discharge shell includes a slag receiving trough and a slag discharge trough connected to the slag receiving trough. The slag discharge trough is inclined upward and extends to the outside of the outer frame. A slag guide plate is inclined downward at the upper end of the slag discharge trough. The slag receiving trough serves to receive the oil slag cleaned and recovered by the slag scraping mesh belt. The slag discharge trough allows the slag scraping mechanism to transport the oil slag collected in the slag receiving trough and discharge it from the continuous fryer. The slag guide plate guides the oil slag scraped out by the slag scraping mechanism.

[0011] Furthermore, the drive assembly includes a geared motor, a drive shaft, and a driven shaft. A mounting plate is fixedly installed on one side of the upper end of the slag scraper. The geared motor is installed at the bottom of the mounting plate. The drive shaft is rotatably installed at the upper end of the slag scraper, and two drive sprockets are symmetrically arranged on the drive shaft. The output end of the geared motor is connected to the drive shaft. The driven shaft is fixedly installed at the lower end of the slag scraper, and two driven sprockets corresponding to the drive sprockets are rotatably arranged on the driven shaft. The output end of the geared motor can drive the drive shaft to rotate synchronously, and the drive shaft can drive the two drive sprockets to rotate synchronously.

[0012] Furthermore, the slag scraping assembly includes a scraper chain and scraper plates. Two scraper chains are spaced apart inside the slag scraping bracket, and multiple scraper plates are spaced apart on the scraper chains. The scraper chains are sleeved on the drive sprocket and the driven sprocket. The scraper plates have an "L"-shaped cross-section and are in contact with the slag scraping bracket. Through the cooperation of the scraper chains with the drive sprocket and the driven sprocket, the scraper chains can be driven inside the slag scraping bracket and drive the scraper plates to move inside the slag scraping bracket to scrape the oil sludge out of the slag discharge shell.

[0013] Furthermore, the upper end of the slag scraper bracket is provided with a slag cleaning component located below the scraper chain. The slag cleaning component includes an L-shaped plate, a pressure plate, and a silicone plate. Both ends of the L-shaped plate are connected to the slag scraper bracket. The silicone plate is located between the L-shaped plate and the pressure plate. The silicone plate can clean the oil sludge on the scraper so that the oil sludge scraped by the scraper falls onto the slag guide plate.

[0014] Furthermore, a chain pressing assembly is provided on the inner side of each corner of the slag scraper support. The chain pressing assembly includes a fixed shaft and a chain pressing plate. The two ends of the fixed shaft are connected to the slag scraper support and the chain pressing plate, respectively. The bottom of the chain pressing plate is in contact with the scraper chain and has an arc-shaped structure. The chain pressing plate is used to limit the position of the scraper chain at the corner of the slag scraper support to ensure that the scraper is in contact with the bottom plate and side plates of the slag discharge shell and to prevent the oil sludge scraped by the scraper from sliding down.

[0015] The beneficial effects of this utility model through the above technical solution are as follows:

[0016] This utility model has a reasonable structure and good performance. It has a slag discharge function, which makes it easy to collect and clean the oil slag that has sunk to the bottom of the oil tank. It can clean the oil slag without stopping the machine and discharge the collected oil slag out of the oil tank. It can ensure the production capacity of the continuous oil slag machine without affecting normal production and avoid the oil slag from staying in the oil for a long time, thus reducing the change in oil quality. At the same time, it can drive the internal conveying mechanism to make lifting and lowering movements, so that the conveying mechanism can move to the outside of the oil tank for cleaning and maintenance operations.

[0017] The transmission mechanism of this utility model can simultaneously drive the screw jacks located on both sides of the outer frame to move. The screw jacks on both sides of the outer frame operate synchronously, driving the support frame to move up and down, so that the support frame drives the lifting frame and the top cover to move up and down. The lifting frame drives the top mesh belt, the bottom mesh belt and the slag scraping mesh belt to move to the outside of the oil tank or into the oil tank, so as to facilitate the cleaning and maintenance of the top mesh belt, the bottom mesh belt and the slag scraping mesh belt.

[0018] This invention uses a power mechanism to drive a scraper belt to transport oil sludge from the bottom of the oil tank to the sludge discharge shell. The sludge discharge shell collects the oil sludge transported by the scraper belt. The sludge receiving groove of the sludge discharge shell is used for the oil sludge transported by the scraper belt, and the sludge discharge groove allows the scraper mechanism to transport the oil sludge collected in the receiving groove and discharge it into the sludge discharge shell. The drive component of the scraper mechanism drives the scraper chain of the scraper assembly to run inside the scraper support, so that the scraper chain drives the scraper to move inside the scraper support, achieving the effect of the scraper scraping the oil sludge in the receiving groove through the sludge discharge groove out of the continuous fryer.

[0019] The L-shaped plate and pressure plate of this utility model's slag cleaning component play a role in fixing the silicone plate. The silicone plate is fixed to the upper part of the two slag scraper side plates. When the slag scraper scrapes out oil slag and runs to the upper part of the slag discharge trough, it comes into contact with the slag scraper. The silicone plate can clean the oil slag on the slag scraper, so that the oil slag scraped out by the slag scraper falls to the slag guide plate and is discharged from the continuous fryer.

[0020] The fixed shaft of the chain pressing assembly of this utility model plays a role in fixing the chain pressing plate. The chain pressing plate cooperates with the scraper chain to limit the position of the scraper chain at the corner of the slag scraping support, ensuring that the scraper keeps in contact with the bottom plate and side plates of the slag discharge shell, preventing the oil sludge scraped by the scraper from sliding down and improving the effect of scraping oil sludge.

[0044] The drive assembly 503 includes a geared motor 5032, a drive shaft 5033, and a driven shaft 5035. A mounting plate 5031 is fixedly installed on one side of the upper end of the slag scraper 501. The geared motor 5032 is installed at the bottom of the mounting plate 5031. The drive shaft 5033 is rotatably installed at the upper end of the slag scraper 501. Two drive sprockets 5034 are symmetrically arranged on the drive shaft 5033. The output end of the geared motor 5032 is connected to the drive shaft 5033. The driven shaft 5035 is fixedly installed at the lower end of the slag scraper 501.

The scraper plates 5022 are in contact with the bottom plate and two outer plates of the slag discharge shell 4. The purpose of this is to prevent the oil slag scraped out by the scraper plates 5022 from the slag receiving trough 401 from sliding down into the slag discharge trough 402. In this embodiment, the two ends of the scraper 5022 are connected to two scraper chains 5021 respectively. Through the cooperation of the scraper chain 5021 with the drive sprocket 5034 and the driven sprocket, while the drive shaft 5033 rotates, the driven sprocket rotates on the driven shaft 5035. The scraper chain 5021 is driven in the scraper bracket 501 and drives the scraper 5022 to move inside the scraper bracket 501, so that the scraper 5022 scrapes the oil residue in the slag receiving trough 401 out of the oil trough 3 through the slag discharge trough 402.

[0046] The upper end of the slag scraper bracket 501 is provided with a slag cleaning component 505 located below the scraper chain 5021. The slag cleaning component 505 includes an L-shaped plate 5051, a pressure plate 5052 and a silicone plate 5053. Both ends of the L-shaped plate 5051 are connected to the slag scraper bracket 501, and the silicone plate 5053 is located between the L-shaped plate 5051 and the pressure plate 5052. In this embodiment, the pressure plate 5052 is bolted to the L-shaped plate 5051. The pressure plate 5052 presses and fixes the silicone plate 5053 onto the L-shaped plate 5051. When the scraper chain 5021 drives the scraper plate 5022 to the silicone plate 5053, the silicone plate 5053 contacts the vertical part of the scraper plate 5022. As the scraper plate 5022 continues to move forward, the silicone plate 5053 cleans the oil residue on the scraper plate 5022, causing the oil residue to fall onto the guide plate 403, thus preventing the scraper plate 5022 from carrying the oil residue back into the slag receiving tank 1.

[0047] Each corner of the scraper support 501 is equipped with a chain clamping assembly 504. The chain clamping assembly 504 includes a fixed shaft 5041 and a chain clamping plate 5042.

The bottom of the chain clamping plate 5042 is in contact with the scraper chain 5021 and has an arc-shaped structure. In this embodiment, there are two chain clamping assemblies 504 on both sides of the scraper support 501. The two chain clamping assemblies restrict the upper and lower positions of the scraper chain 5021 at the corner of the scraper support 501, respectively. The chain clamping assembly 504 includes two fixed shafts 5041. Through the contact between the chain clamping plate 5042 and the scraper chain 5021, it is ensured that the scraper 5022 is in contact with the bottom plate and two side plates of the slag discharge shell 4, thereby preventing the oil sludge scraped by the scraper 5022 from sliding down.

[0048] In this embodiment, tensioning components are installed on both sides of the lower end of the scraper bracket 501. Each tensioning component includes a fixing plate 1701, a screw, and a tensioning shaft. The fixing plate has an "L"-shaped structure and is bolted to the outside of the scraper bracket 501. The screw is fixed to the fixing plate with a nut, and one end of the tensioning shaft is fitted onto the screw. The tensioning components allow adjustment of the tension of the scraper chain 5021 to ensure it is at a suitable tension. This allows the scraper chain 5021 to drive the scraper plate 5022, enabling the scraper plate 5022 to scrape the oil residue from the slag receiving trough 401 through the slag discharge trough 402 and out of the continuous fryer. The tensioning shaft has a through hole fitted onto the screw, and both sides of the tensioning shaft are provided with locking nuts threaded to the screw. The scraper bracket 501 has a slotted hole corresponding to the screw position, through which the other end of the tensioning shaft passes. The hole is connected to the driven shaft 5035. When adjusting the tension of the scraper chain 5021, the locking nuts on both sides of the tensioning shaft can be loosened so that the tensioning shaft can move laterally on the screw. When the tensioning shaft moves, it can drive the driven shaft 5035 to move, and the driven shaft 5035 drives the driven sprocket to move, thereby achieving the effect of adjusting the tension of the scraper chain 5021. After adjusting the tension of the scraper chain 5021, the locking nuts can be rotated again to fix the tensioning shaft.

[0049] The working principle of this utility model is as follows: When frying materials, the materials are conveyed from the feed hood 6 into the oil tank 3. The geared motor drives the upper mesh belt 16 and the lower mesh belt 18 to be transported in the lifting frame 2. The materials are moved towards the discharge hood 7 through the lower mesh belt 18 of the upper mesh belt 16. The frying operation is completed during the material conveying. Then the fried materials are discharged through the discharge hood 7.

[0050] During the frying process, the first geared motor 5032 and the second geared motor 20 are started. The output end of the second geared motor 20 drives the scraper drive shaft 21 to rotate. The scraper drive shaft 21 drives one of the scraper driven shafts 22 to rotate through the sprocket and chain structure. Under the action of the scraper mesh belt 19, the two scraper driven shafts 21 rotate synchronously. The scraper mesh belt 19 is used for transmission in the oil tank 3. The scraper mesh belt 19 transports the oil residue that has sunk to the bottom of the oil to the slag receiving tank 401 and drops into the slag receiving tank 401.

[0051] The output of the geared motor 5032 drives the drive shaft 5033 to rotate. The drive shaft 5033 drives the drive sprocket 5034 to rotate. With the cooperation of the scraper chain 5021, the drive sprocket 5034, and the driven sprocket, the driven sprocket rotates on the driven shaft 5035. The scraper chain 5021 is driven within the slag scraper bracket 501. During the transmission process, the scraper chain 5021 drives the scraper plate 5022 to move inside the scraper bracket 501. The scraper plate 5022 fills the slag receiving trough 401. The oil residue inside is scraped out through the slag discharge trough 402. Each scraper 5022 passes through the silicone plate 5053 in sequence. After the scraper 5022 moves to the silicone plate 5053, the silicone plate 5053 contacts the vertical part of the scraper 5022. The scraper 5022 continues to move forward, and the silicone plate 5053 cleans the oil residue on the scraper 5022, causing the oil residue to fall onto the guide plate 403 and then slide down on the guide plate 403, thus achieving the effect of discharging the oil residue that has sunk to the bottom of the oil from the continuous fryer.

[0052] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
