Description

Technical Field

[0001] This utility model relates to the field of tea processing technology, and in particular to a tea-frying machine with handles. Background Technology

[0002] Tea processing includes roasting, or stir-frying, which involves baking the tea over a low heat to remove moisture. Traditionally, tea is stir-fried manually, but this method results in low output and inefficiency. Currently, a type of tea-frying machine, such as the one described in CN219920163U, is commonly used. This machine includes a main frame, a tea-frying pan mounted on the main frame, and a stirring device mounted above the pan via a support frame. The stirring device consists of a sleeve bolted to the bottom of a connecting shaft and multiple fixed clamps evenly distributed around the sleeve, with bamboo branches clamped between the clamps. A geared motor drives the stirring device to rotate, thus stirring the tea leaves. Adjusting handwheels and lifting screws move the stirring device up and down, further stirring the tea leaves. During the stirring process, as per the instruction manual... Figure 2 As shown in the top view of the tea-frying pan, the bottom plate has multiple straight ribs radiating from the center to the rim. Between adjacent straight ribs are curved ribs. When the tea leaves rotate in the pan with the stirring assembly and pass over these curved ribs, the leaves curl along these ribs. However, as indicated in the instruction manual... Figure 1 The stirring component in the pan has a specific structure that uses bamboo sticks clamped by fixed clamps. The bamboo sticks are perpendicular to the bottom plate of the pan. That is, the sweeping angle formed between the plane of the bamboo sticks and the plane of the bottom plate of the pan, which is used to hold the tea leaves and rotate the bamboo sticks in the pan, is 90°. During the stirring process, the bottom of the bamboo sticks will directly contact the tea leaves and the ribs. However, the bamboo sticks set perpendicular to the bottom plate of the pan will increase the collision force between the tea leaves and the ribs. The tea leaves will break when passing through the ribs, which will affect the quality of the tea. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tea frying machine with a handle, which is mainly used to fry tea and roll the tea leaves into strips, so as to reduce the breakage rate of tea leaves and ensure the quality of tea leaves.

[0004] This utility model discloses a tea-frying machine with handles, including a frame, a tea-frying pan mounted on the frame, and a stirring device mounted above the tea-frying pan. The tea-frying pan includes a bottom plate mounted on the frame, a pan ring mounted around the bottom plate, and a heating mechanism mounted on the lower surface of the bottom plate. The upper surface of the bottom plate has multiple straight ribs radiating from the center of the pan to the pan ring, and arc-shaped ribs between adjacent straight ribs. The stirring device includes a handle assembly, a connecting plate, and a driving mechanism for rotating and moving the handle assembly up and down. The handle assembly is mounted around the connecting plate and extends outward along the radial direction of the connecting plate. The output end of the driving mechanism is fixed to the center of the connecting plate to drive the handle assembly to rotate. The lower end of the handle assembly forms a curled cavity with the concave surface of the arc-shaped ribs, which gradually decreases in area as the handle assembly rotates. The handle assembly is inclined on the connecting plate, and the sweeping angle formed between the plane of the handle assembly and the plane of the bottom plate is an acute angle.

[0005] Furthermore, the handle assembly includes a fixed bracket, a pressure plate, and a bamboo branch handle disposed between the fixed bracket and the pressure plate. The fixed bracket is inclinedly disposed around the connecting plate, and the bamboo branch handle is disposed on the fixed bracket along the inclined direction of the fixed bracket. The pressure plate is disposed at the upper end of the bamboo branch handle and is connected to the fixed bracket by bolts to fix the bamboo branch handle. The sweeping angle formed by the plane where the bamboo branch handle is located and the plane where the bottom plate of the pot is located is less than 90° and greater than 60°.

[0006] As a preferred embodiment, the sweeping angle is 70°.

[0007] Furthermore, the lower surface of the pot bottom plate is provided with a vertically downward extending tie rod, and the frame is provided with an auxiliary support located at the bottom of the tea-frying pot. One end of the tie rod is connected to the pot bottom plate, and the other end is connected to the auxiliary support.

[0008] In a preferred embodiment, the pull rod includes a first sleeve and a second sleeve. One end of the first sleeve is connected to the bottom plate of the pot, and the other end is hollow and has an internal thread. One end of the second sleeve is rotatably connected to the frame, and the other end has an external thread that matches the internal thread. The second sleeve is threadedly connected to the first sleeve.

[0009] Furthermore, the bottom plate of the pot is provided with a discharge port and a discharge hopper connected to the discharge port. Below the discharge port, there is a baffle assembly located in the discharge hopper for controlling the discharge from the discharge port. The baffle assembly includes a baffle plate adapted to the discharge port, a first rotating rod for controlling the movement of the baffle plate, and a second rotating rod for fixing the baffle plate. One side of the baffle plate is provided with a hinge and is connected to the bottom plate of the pot. The first rotating rod is fixed to the bottom of the baffle plate and one end extends through the discharge hopper in a direction away from the tea frying machine. The second rotating rod is located on the side of the discharge port away from the hinge. One end of the second rotating rod is hinged to the bottom of the bottom plate of the pot, and the other end extends through the discharge hopper and moves left and right along a plane parallel to the bottom plate of the pot. The discharge hopper is provided with a first through groove for the movement of the first rotating rod and a second through groove for the movement of the second rotating rod.

[0010] In a preferred embodiment, the first rotating rod includes a rod body and a stop bar. The rod body is rotatably disposed inside the discharge hopper, and the stop bar is fixedly disposed on the rod body and rotates with the rod body to drive the baffle plate to rotate.

[0011] Furthermore, the frame is equipped with a control console, which includes a first controller for controlling the rotation of the drive mechanism, a second controller for controlling the lifting and lowering of the drive mechanism, and a third controller for controlling the start and stop of the heating mechanism; the first controller is electrically connected to the drive mechanism, the second controller is electrically connected to the drive mechanism, and the third controller is electrically connected to the heating mechanism.

[0013] As a preferred embodiment, the first relay, the second relay, and the third relay are all electrically connected to an alarm device.

[0014] The beneficial effects of this utility model are as follows: by setting an inclined handle assembly on the connecting plate, the sweeping angle formed by the plane of the handle assembly and the plane of the bottom plate of the pot is an acute angle, thereby increasing the contact area between the lower end of the handle assembly and the tea leaves, reducing the direct collision force between the tea leaves and the arc-shaped ribs, reducing the breakage rate of the tea leaves, and the inclined handle assembly can stir-fry the tea leaves more evenly, so that the tea leaves are heated evenly in all parts, improving the efficiency of tea frying and the quality of the tea leaves.

Detailed Implementation

[0025] The present invention will be further described below.

[0026] This utility model provides a tea-frying machine with a handle, mainly used for frying tea and rolling tea leaves into strips. It includes a frame 1, a tea-frying pan 2 mounted on the frame 1, and a stirring mechanism 3 positioned above the tea-frying pan 2. The tea-frying pan 2 includes a bottom plate 21 mounted on the frame 1, a pan ring 22 circumferentially mounted on the bottom plate 21, and a heating mechanism 23 on the lower surface of the bottom plate 21. The upper surface of the bottom plate 21 has multiple straight ribs 211 radiating from the center of the pan towards the pan ring 22, with arc-shaped ribs 212 between adjacent straight ribs 211. The stirring mechanism 3 includes a handle assembly 31, a connecting plate 32, and... A drive mechanism 33 is used to drive the handle assembly 31 to rotate and move up and down. The handle assembly 31 is arranged around the connecting plate 32 and extends outward along the radial direction of the connecting plate 32. The output end of the drive mechanism 33 is fixed to the center of the connecting plate 32 to drive the handle assembly 31 to rotate and move up and down. The lower end of the handle assembly 31 and the concave surface of the arc rib 212 form a curled cavity 41 whose area gradually decreases as the handle assembly 31 rotates. The handle assembly 31 is inclined on the connecting plate 32, and the sweeping angle 4 formed by the plane of the handle assembly 31 and the plane of the bottom plate 21 is an acute angle.

[0027] like Figures 1-5 As shown, the tea-frying machine includes a frame 1, a tea-frying pan 2 mounted on the frame 1, and a stirring mechanism 3 mounted above the tea-frying pan 2. The tea-frying pan 2 includes a bottom plate 21 mounted on the frame 1, a pan ring 22 circumferentially mounted on the bottom plate 21, and a heating mechanism 23 mounted on the lower surface of the bottom plate 21. Both the frame 1 and the tea-frying pan 2 can adopt the structure described in CN219920163U "A Tea-Frying Machine with Handles". The heating mechanism 23 includes a heating tube for heating and insulation cotton for heat preservation. The upper surface of the bottom plate 21 is provided with multiple straight ribs 211 radiating from the center of the pan to the pan ring 22. Arc-shaped ribs 212 are provided between adjacent straight ribs 211. This allows the tea leaves to flip when they encounter straight ribs 211 as they move with the stirring mechanism 3, thus achieving the purpose of stir-frying the tea leaves. Then, through the arc-shaped ribs 212 positioned between the straight ribs 211, the tea leaves curl into strips following the curvature of the arc-shaped ribs 212. The stirring mechanism 3 includes a handle assembly 31, a connecting plate 32, and a drive mechanism 33 for rotating and moving the handle assembly 31 up and down. The drive mechanism 33 can be a combination of existing rotating and lifting mechanisms, or it can employ a structure such as the lifting screw, spline shaft, and active bevel gear described in CN219920163U "A Handle-Type Tea Stir-Frying Machine". Figure 1As shown, the handle assembly 31 extends outward along the radial direction of the connecting plate 32 and is spaced apart around the circumference of the connecting plate 32. The number of handle assemblies 31 can be arranged according to actual needs. The connecting plate 32 is then connected to the output end of the drive mechanism 33. To ensure the stability of the handle assembly 31 when rotating on the connecting plate 32, the center of the connecting plate 32 is fixedly connected to the output end of the drive mechanism 33. The drive mechanism 33 drives the connecting plate 32 to rotate and move up and down, thereby driving the handle assembly 31 to rotate and move up and down, achieving the purpose of stir-frying the tea leaves. To ensure that the bottom of the handle assembly 31 does not damage the tea leaves during the stirring process, such as... Figure 1-3 As shown, the lower end of the handle assembly 31 and the concave surface of the arc-shaped rib 212 form a curling cavity 41 whose area gradually decreases as the handle assembly 31 rotates. The tea leaves curl within this curling cavity 41. The sweeping angle 4 formed by the plane of the handle assembly 31 and the plane of the pot bottom plate 21 is an acute angle. Specifically, the handle assembly 31 can be tilted on the connecting plate 32, so that the lower end of each handle assembly 31 on the connecting plate 32 is tilted in one direction and the angle formed with the pot bottom plate 21 is less than 90°. By setting the tilted handle assembly 31 on the connecting plate 32, the sweeping angle 4 formed by the plane of the handle assembly 31 and the plane of the pot bottom plate 21 is an acute angle, thereby increasing the contact area between the lower end of the handle assembly 31 and the tea leaves, reducing the direct collision force between the tea leaves and the arc-shaped rib 212, reducing the breakage rate of the tea leaves, and the tilted handle assembly 31 can stir-fry the tea leaves more evenly, so that the tea leaves are heated evenly in all places, improving the efficiency of tea frying and the quality of the tea leaves.

[0028] The aforementioned handle assembly 31 can use a fixed clamping plate, as described in CN219920163U "A Handle-Type Tea Frying Machine," to clamp the bamboo branches onto the connecting plate 32. However, it should be noted that the sweeping angle 4 formed between the bottom of the bamboo branch and the bottom plate 21 is an acute angle. Therefore, the bamboo branch needs to be tilted between the fixed clamping plates, or the fixed clamping plates need to be tilted onto the connecting plate, so that the sweeping angle formed between the plane of the bamboo branch and the plane of the bottom plate is an acute angle. However, since the fixed clamping plate is set between two clamping plates, the connection is unstable when it is tilted. To ensure the connection stability between the fixed clamping plate and the connecting plate, it is convenient to tilt the handle assembly 31 onto the connecting plate 32, such as... Figure 2 , Figure 3As shown in the figure, the row handle assembly 31 includes a fixed bracket 311, a pressing plate 312, and a bamboo branch row handle 313 disposed between the fixed bracket 311 and the pressing plate 312. The fixed bracket 311 includes a horizontal plate 3111 and a vertical plate 3112. The horizontal plate 3111 is fixedly connected to the connecting disc 32. The vertical plate 3112 is inclined and disposed on one side of the horizontal plate 3111. The bamboo branch row handle 313 is disposed on the fixed bracket 311 along the inclined direction of the vertical plate 3112. The sweeping angle 4 formed by the plane where the bamboo branch row handle 313 is located and the plane where the pot bottom plate 21 is located is less than 90° and greater than 60°. The pressing plate 312 is disposed at the upper end of the bamboo branch row handle 313 and is connected to the fixed bracket 311 by bolts 314 to fix the bamboo branch row handle 313. The fixed bracket 311 is designed to be in the shape of "乁". The horizontal plate 3111 is fixedly connected to the connecting disc 32. The vertical plate 3112 is inclined and disposed on the horizontal plate 3111. Connecting the horizontal plate 3111 to the connecting disc 32 can ensure the connection stability between the fixed bracket 311 and the connecting disc 32. Then, the bamboo branch row handle 313 is disposed on the fixed bracket 311 along the inclined direction of the vertical plate 3112, and the bamboo branch row handle 313 is fixed to the fixed bracket 311 by the pressing plate 312. The pressing plate 312 is provided with bolts 314. The bolts 314 penetrate through the pressing plate 312 and are fixedly connected to the vertical plate 3112. One end of the bolt 314 connected to the pressing plate 312 is provided with a fixing nut 3141. By screwing the fixing nut 3141, the bamboo branch row handle 313 disposed between the pressing plate 312 and the vertical plate 3112 is tightened to prevent it from falling during use. And installing the bamboo branch row handle 313 by using the bolts 314 can also facilitate the replacement of the bamboo branch row handle 313 in the later stage. To ensure the pressing of the pressing plate 312 on the bamboo branch row handle 313, a back-tightening nut 3142 threadedly connected to the bolt 314 is also provided. By changing the angle between the vertical plate 3112 and the horizontal plate 3111 of the fixed bracket 311, the inclination angle of the bamboo branch row handle 313 is controlled, that is, the included angle of the sweeping angle 4 formed by the plane where the bamboo branch row handle 313 is located and the plane where the pot bottom plate 21 is located. When the included angle 42 formed between the vertical plate 3112 and the horizontal plate 3111 is greater than 90° and less than 120°, the sweeping angle 41 formed by the plane where the bamboo branch row handle 313 disposed along the inclined direction of the vertical plate 3112 and the plane where the pot bottom plate 21 is located is less than 90° and greater than 60°. As a preferred method, the sweeping angle 41 formed by the plane where the bamboo branch row handle 313 is located and the plane where the pot bottom plate 21 is located is 70°. Setting the sweeping angle 41 formed by the plane where the bamboo branch row handle 313 is located and the plane where the pot bottom plate 21 is located to 70°, that is, the included angle 42 formed between the vertical plate 3112 and the horizontal plate 3111 of the fixed bracket 311 is 110°. Such a setting makes it so that not too much of the bottom of the bamboo branch row handle 313 contacts the pot bottom plate 21, resulting in too much tea adhering to the gaps of the bamboo branch row handle 313.

[0029] To control the contact area between the tilted bamboo branch handle 313 and the tea leaves, and to reduce the impact force when the tea leaves are moved by the bamboo branch handle 313 to contact the straight rib 211 or the arc-shaped rib 212 during the rotation of the handle assembly, while also reducing the possibility of tea leaves adhering to the bamboo branch handle 313, the length of the lower end of the bamboo branch handle 313 near the arc-shaped rib 212 is less than the length of the side away from the arc-shaped rib 212. By trimming the lower end of the bamboo branch handle 313 to form an inclined surface, the contact area between the bamboo branch handle 313 and the tea leaves is further increased, reducing the impact force generated when the tea leaves move to the straight rib 211 or the arc-shaped rib 212 as the bamboo branch handle 313 moves, thus ensuring the quality of the tea leaves.

[0030] The aforementioned heating mechanism 23 can use existing heating elements and insulation cotton to dry the moisture on the tea leaves; however, when the bottom plate 21 is heated by the heating mechanism 23 for a long time, bulging is likely to occur, causing the surface of the bottom plate 21 to be uneven. During the process of stirring the tea leaves with the bamboo handle 313, the tea leaves are not stirred evenly, and the impact force generated when the tea leaves move with the bamboo handle 313 to the straight ribs 211 or the arc-shaped ribs 212 is increased, resulting in damage to the tea leaves; in order to ensure the surface flatness of the bottom plate 21, such as Figure 5 , Figure 6 As shown, the lower surface of the pot bottom plate 21 is also provided with a vertically downward extending pull rod 25. One end of the pull rod 25 is connected to the pot bottom plate, and the other end is connected to the auxiliary support 12 of the frame 1; specifically, as shown... Figure 5 As shown, the tea-frying pan 2 is mounted on the frame 1. To ensure the stable mounting of the tea-frying pan 2, an X-shaped auxiliary support 12 is provided below the tea-frying pan 2. A pull rod 25 is provided on the lower surface of the pan bottom plate 21, and one end of the pull rod 25 is connected to the auxiliary support 12. By providing the pull rod 25 between the auxiliary support 12 and the pan bottom plate 21, the stability of the pan bottom plate 21 is ensured. As a preferred method, to facilitate the adjustment of the length of the pull rod 25, a tension is applied to the pan bottom plate 21 according to actual needs, such as... Figure 6 As shown, the pull rod 25 includes a first sleeve rod 251 and a second sleeve rod 252. One end of the first sleeve rod 251 is connected to the bottom plate 21 of the pot, and the other end is hollow and has an internal thread. One end of the second sleeve rod 252 is rotatably connected to the auxiliary bracket 12, and the other end has an external thread that matches the internal thread. The second sleeve rod 252 is threadedly connected to the first sleeve rod 251. The second sleeve rod 252 passes through the auxiliary bracket 12 and is rotatably connected through a bearing. By setting the first sleeve rod 251 and the second sleeve rod 252, when it is necessary to adjust the length of the pull rod 25 and thus adjust the pulling force generated by the pull rod 25 on the bottom plate 21, it is only necessary to screw on the second sleeve rod 252 and adjust the connection position between the second sleeve rod 252 and the first sleeve rod 251 to adjust the length of the pull rod 25 and thus adjust the pulling force generated by the pull rod 25 on the bottom plate 21.

[0031] To facilitate the removal of the roasted tea leaves from the tea roasting machine, such as Figure 1 , Figure 4 , Figure 7 , Figure 8 As shown, the bottom plate 21 of the pot is provided with a discharge port 213 and a discharge hopper 214 connected to the discharge port 213. Below the discharge port 213, there is a baffle assembly 26 located in the discharge hopper 214 for controlling the discharge from the discharge port 213. The baffle assembly 26 includes a baffle plate 261 adapted to the discharge port 213, a first rotating rod 262 for controlling the movement of the baffle plate 261, and a second rotating rod 263 for fixing the baffle plate 261. A hinge 264 is provided on one side of the baffle plate 261 and is hinged to the bottom plate 21. The first rotating rod 262 is fixed on the baffle plate 261 and one end extends through the discharge hopper 214 in a direction away from the tea frying machine; the second rotating rod 263 is located on the side of the discharge port 213 away from the hinge 264. One end of the second rotating rod 263 is hinged to the bottom of the pot bottom plate 21, and the other end passes through the discharge hopper 214 and moves left and right along a plane parallel to the pot bottom plate 21. The discharge hopper 214 has a first through groove 265 for the movement of the first rotating rod 262 and a second through groove 266 for the movement of the second rotating rod 263. The operator holds the end of the first rotating rod 262 that passes through the discharge hopper 214, which drives the baffle plate 261 fixed to the first rotating rod 262 to rotate around the hinge connection. When tea is being stir-fried on the pot bottom plate 21, the first rotating rod 262 drives the baffle plate 261 to rotate to the side of the discharge port 213 away from the hinge 264. 3. In a parallel direction, the baffle plate 261 blocks the outlet 213 to prevent tea leaves from falling. When the first rotating rod 262 rotates to a direction parallel to the outlet 213, the second rotating rod 263 moves towards the side closer to the outlet 213, fixing the baffle plate 261 between the bottom plate 21 and the second rotating rod 263 to prevent it from falling. When tea leaves need to be added, the second rotating rod 263 moves away from the outlet 213, no longer fixing the position of the baffle plate 261. The first rotating rod 262 rotates the baffle plate 261 to a direction perpendicular to the outlet 213, opening the outlet 213 and allowing the tea leaves to be output from the outlet 213. At the same time, the discharge hopper 21... The outer wall of the 4 is provided with a first through groove 265 for sliding the first rotating rod 262. The first through groove 265 is arc-shaped so as to drive the baffle plate 261 to flip inside the discharge hopper 214 to block or open the discharge port 213. The outer wall of the discharge hopper 214 is also provided with a second through groove 266 for moving the second rotating rod 263 left and right. The second through groove 266 is elongated so as to move the second rotating rod left and right. The connection between the second rotating rod 263 and the bottom plate 21 can be specifically adopted by welding a screw rod to the bottom of the bottom plate 21 and welding a collar to the end of the second rotating rod. The collar is fitted on the screw rod and can rotate with the screw rod as the axis, thereby driving the rod body of the second rotating rod 263 to rotate left and right.

[0032] Because the sliding path of the first rotating rod 262 is relatively long and arc-shaped, the size of the first through groove 265 required to be opened on the discharge hopper 214 is relatively large. When tea leaves are discharged outward along the discharge hopper 214, there is a problem of leakage from the first through groove 265 and the second through groove 266. As a preferred method, to reduce the possibility of tea leaves leaking from the first through groove 265 and the second through groove 266, such as... Figure 1 , Figure 9 As shown, the first rotating rod 262 includes a rod body 2621 and a stop rod 2622. The rod body 2621 is rotatably disposed within the discharge hopper 214, and the stop rod 2622 is fixedly disposed on the rod body 2621 and rotates with the rod body 2621 to drive the baffle plate 261 to rotate. By rotatably disposing the rod body 2621 of the first rotating rod 262 within the discharge hopper 214, the operator rotates the first rotating rod 262, thereby driving the stop rod 2622 fixed on the rod body 2621 to rotate. During the rotation, the stop rod 2622 contacts the baffle plate 261, thereby causing the baffle plate 261 to flip until the stop rod 2622 rotates to the position of the discharge port 213. When the baffle plate 261 is in a parallel position on the plane, it covers the discharge port 213. Then, the second rotating rod 263 is moved to the side closer to the discharge port 213, fixing the baffle plate 261 between the bottom plate 21 and the second rotating rod 263. At this time, the first rotating rod 262 will rotate on its own to the position of the discharge port 213 due to the gravity of the baffle rod 2622. When tea leaves need to be discharged, the second rotating rod 263 only needs to be moved away from the discharge port 213. At this time, there is no baffle rod 2622 to abut under the baffle plate 261, so the baffle plate 261 will rotate on its own to the position perpendicular to the discharge port 213 due to gravity, thereby opening the discharge port 213 for feeding.

[0033] To facilitate separate control of the start and stop of the drive mechanism 33 and the heating mechanism 23, and to facilitate operation by the operator, such as Figure 1 As shown, the frame 1 is equipped with a control console 5, which includes a first controller 51 for controlling the rotation of the drive mechanism 33, a second controller 52 for controlling the lifting and lowering of the drive mechanism 33, and a third controller 53 for controlling the start and stop of the heating mechanism 23. The first controller 51 is electrically connected to the drive mechanism 33, the second controller 52 is electrically connected to the drive mechanism 33, and the third controller 53 is electrically connected to the heating mechanism 23. By controlling the rotation of the drive mechanism 33 with the first controller 51, controlling the lifting and lowering of the drive mechanism 33 with the second controller 52, and controlling the start and stop of the heating mechanism 23 with the third controller 53, the operator can control each mechanism simply by operating the control console 5.

[0034] To ensure the tea-frying machine automatically stops based on the required frying time, preventing excessive heating and curling of the tea leaves and reducing manual monitoring, the first controller 51 includes a first relay, the second controller 52 includes a second relay, and the third controller 53 includes a third relay. The first relay is electrically connected to the drive mechanism 33, the second relay is electrically connected to the drive mechanism 33, and the third relay is electrically connected to the heating mechanism 23. By setting the first, second, and third relays for timing, the first, second, and third controllers can be scheduled to stop at specific times. To facilitate timely reminders to operators for actions such as adding tea leaves after frying or periodically checking the frying process, each of the first, second, and third relays is electrically connected to an alarm device 54. When the first relay controls the first controller 51 to stop, the second relay controls the second controller 52 to stop, or the third relay controls the third controller 53 to stop, the alarm device 54 will sound an alarm to remind the operator that the frying process is complete.
