Description

Technical Field

[0001] This application relates to the technical field of chestnut processing equipment, and in particular to a chestnut stir-frying machine. Background Technology

[0002] Roasted chestnuts are a traditional flavored food made primarily from chestnuts and cooking oil. When there are a large quantity of chestnuts to be processed, they are usually processed using a chestnut roasting machine. During production, workers place the chestnut raw materials and auxiliary ingredients in a wok and stir-fry until the chestnuts are cooked.

[0003] Stir-frying chestnuts produces a large amount of smoke, which can easily pollute the environment if directly released into the air. Therefore, woks are usually equipped with multiple layers of nano-activated carbon filter cotton to filter the oil fumes from the smoke. When the smoke passes through the nano-activated carbon filter cotton, some of the oil fumes are trapped in the nano-activated carbon filter cotton. However, when the oil fume content in the smoke is high, the smoke after being filtered by the nano-activated carbon filter cotton still contains oil fumes, which may cause the oil fumes to be released into the air, thus having an adverse impact on the environment. Utility Model Content

[0004] In order to reduce the adverse environmental impact of cooking fumes, this application provides a chestnut stir-fry machine.

[0005] The chestnut stir-frying machine provided in this application adopts the following technical solution: A chestnut stir-frying machine includes a frame and a wok installed in the frame. The wok is equipped with a stir-frying spatula for stir-frying chestnuts. A heating component is provided on the lower side of the wok. A filter screen is installed on the frame on the upper side of the wok. The upper side of the filter screen is provided with multiple layers of first nano-activated carbon filter cotton. A secondary filter component for filtering flue gas is provided on the side of the first nano-activated carbon filter cotton away from the wok.

[0006] By adopting the above technical solution, chestnuts are placed in a wok, heated by a heating element, and the chestnuts are stir-fried using a stir-frying spatula. The resulting fumes move upwards and pass through a filter screen and multiple layers of first-layer nano-activated carbon filter cotton, thereby removing some of the oil fumes from the fumes. The fumes filtered by the filter screen and first-layer nano-activated carbon filter cotton continue to move to a secondary filtration component for further removal of oil fumes, thus ensuring that the fumes after secondary filtration meet emission standards and reduce the adverse environmental impact of oil fumes.

[0007] Optionally, the secondary filtration assembly includes an extraction box installed on one side of the upper side of the frame and communicating with the interior of the frame, and a filter box provided on the other side of the upper side of the frame. A centrifugal fan is provided between the extraction box and the filter box to connect the two. The filter box contains multiple air purifier composite dual-barrel filter elements. The upper side of the filter box is open and covered by a sealing plate. The upper end of the air purifier composite dual-barrel filter element passes through the sealing plate and communicates with the outside. The extraction box and the filter box are covered by the same mounting frame. A second nano-activated carbon filter cotton is provided on the upper side of the mounting frame.

[0008] By adopting the above technical solution, the flue gas in the frame is drawn by a centrifugal fan and moved to the filter box through the extraction box. At this time, the sealing plate seals the filter box, reducing the possibility of oil fumes being discharged from the top of the filter box. This allows the composite double-barrel filter element of the air purifier to fully contact the flue gas and remove the oil fumes from it. The flue gas filtered by the composite double-barrel filter element of the air purifier continues to move upward to pass through the mounting frame and is filtered again by the second nano-activated carbon filter cotton. This ensures that the filtered flue gas meets the emission standards and reduces the adverse environmental impact of oil fumes.

[0009] Optionally, the outer side of the air purifier composite dual-barrel filter element is provided with a third nano-activated carbon filter cotton that is arranged along the circumference of the air purifier composite dual-barrel filter element and wrapped around the outer circumferential surface of the air purifier composite dual-barrel filter element.

[0010] By adopting the above technical solution, when the composite dual-barrel filter element of the air purifier filters the oil fumes in the flue gas, it first comes into contact with the third nano-activated carbon filter cotton on the outside of the composite dual-barrel filter element and some of the oil fumes are intercepted. This pre-filters the flue gas that comes into contact with the composite dual-barrel filter element of the air purifier, making it easier to remove the oil fumes in the flue gas and improve the flue gas filtration effect.

[0011] Optionally, the lower side of the sealing plate is bonded to the filter box, and the sealing plate is fixedly connected to the filter box by bolts.

[0012] By adopting the above technical solution, the sealing plate seals the filter box by bonding and fixing it with bolts, which improves the sealing performance of the gap between the sealing plate and the side wall of the filter box, reduces the possibility of some flue gas escaping through the gap between the sealing plate and the filter box, and reduces the adverse effects on the flue gas filtration effect.

[0013] Optionally, a filter frame is fitted around the outside of the filter screen and arranged circumferentially along the filter screen. The edges of the first nano-activated carbon filter cotton are all inserted into the filter frame. One side of the filter frame is hinged to the inner wall of the frame, and the other side has an oblong hole. A screw is provided on the inner wall of the upper end of the frame. The screw passes through the oblong hole and is threaded with a nut.

[0014] By adopting the above technical solution, the filter screen and the first nano-activated carbon filter cotton are installed on the frame via the filter frame. When replacement is required, the nut is turned until it disengages from the screw, driving the filter frame to rotate along its hinge side. At this time, the screw disengages from the waist-shaped hole. The filter frame is then rotated until it is easy to remove and replace the first nano-activated carbon filter cotton, improving replacement efficiency and further facilitating the removal of oil fumes from the flue gas, thus reducing the adverse environmental impact of oil fumes.

[0015] Optionally, two stir-fry spatulas are provided, with the lower side of each spatula close to the inner wall of the wok. Each spatula has an upward-facing stir-fry groove on its upper side, and the lower side of the stir-fry groove is arc-shaped. The frame is provided with a drive unit that drives the stir-fry spatulas to rotate along the rotation axis of the wok.

[0016] By adopting the above technical solution, the driving component drives the stir-frying spatula to rotate around the rotation axis of the wok, thereby stir-frying the chestnuts in the wok. The stir-frying groove opened on the upper side of the stir-frying spatula makes it easy for the chestnuts pushed by the stir-frying spatula to pass over the stir-frying spatula through the stir-frying groove, reducing the possibility that some chestnuts are always pushed by the stir-frying spatula and are difficult to stir-fry evenly, thus reducing the adverse effects on the stir-frying effect.

[0017] Optionally, the driving component includes a drive shaft whose upper end passes through the wok and is rotatably connected to the wok. The ends of the stir-frying spatulas that are close to each other are fixed to the drive shaft and are symmetrical along the rotation axis of the wok. The stir-frying spatulas are all inclined and in opposite directions. A motor is installed at the lower end of the drive shaft and is fixedly connected to the inner wall of the frame.

[0018] By adopting the above technical solution, the motor drives the stir-frying spatula to rotate around the drive shaft and stir-fry the chestnuts. The tilted stir-frying spatula further facilitates the stir-frying of chestnuts while reducing the possibility that some chestnuts are always pushed by the chestnuts and are difficult to stir-fry evenly, thus reducing the adverse effects on the stir-frying effect.

[0019] Optionally, the heating assembly includes insulation cotton disposed on the outside of the wok, and multiple electromagnetic strips evenly distributed circumferentially along the rotation axis of the wok are installed on the outside of the insulation cotton. A coil is provided between adjacent electromagnetic strips to connect them. An electromagnetic induction heating power supply for controlling the electromagnetic strips to be energized and heated is provided on the lower side of the frame body.

[0020] By adopting the above technical solution, the electromagnetic induction heating power supply powers the electromagnetic strip through the coil, thereby heating the wok through the electromagnetic strip. The insulation cotton keeps the wok warm, reducing the possibility of heat loss. While heating the wok quickly, it also reduces the possibility of the wok temperature dropping rapidly, thus minimizing the adverse effects on chestnut stir-frying.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The wok is heated by the heating element, and the chestnuts in the wok are stir-fried by the stir-frying spatula. The resulting smoke moves upward and passes through the filter screen and multiple layers of first nano-activated carbon filter cotton, thereby removing some of the oil fumes from the smoke. The smoke after being filtered by the filter screen and the first nano-activated carbon filter cotton continues to move to the secondary filter element to further remove oil fumes, so that the smoke after secondary filtration meets the emission standards and reduces the adverse impact of oil fumes on the environment. 2. The flue gas is drawn from the frame by a centrifugal fan and moved to the filter box through the extraction box. At this time, the sealing plate seals the filter box to reduce the possibility of oil fumes being discharged from the top of the filter box. This allows the composite double-barrel filter element of the air purifier to fully contact the flue gas and remove the oil fumes from the flue gas. The flue gas filtered by the composite double-barrel filter element of the air purifier continues to move upward to pass through the mounting frame and is filtered again by the second nano-activated carbon filter cotton, so that the filtered flue gas meets the emission standards and reduces the adverse environmental impact of oil fumes. 3. The driving component drives the stir-frying spatula to rotate around the rotation axis of the wok, thereby stir-frying the chestnuts in the wok. The stir-frying groove on the upper side of the stir-frying spatula makes it easy for the chestnuts pushed by the stir-frying spatula to pass over the stir-frying spatula through the stir-frying groove, reducing the possibility that some chestnuts are always pushed by the stir-frying spatula and are difficult to stir-fry evenly, thus reducing the adverse effects on the stir-frying effect.

Detailed Implementation

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] This application discloses a chestnut stir-frying machine. (Refer to...) Figure 1 and Figure 2 A chestnut stir-frying machine includes a frame 1 and a wok 2 installed in the frame 1. The lower side of the inside of the frame 1 is provided with an installation hole 11 adapted to the wok 2. An installation ring 21 is sleeved and fixedly connected to the upper side of the wok 2. The lower side of the wok 2 passes through the installation hole 11, and the installation ring 21 overlaps the frame 1.

[0030] Reference Figure 2 and Figure 3 The lower side of the exterior of the wok 2 is provided with a heating component 3 for heating the wok 2. The wok 2 contains two circumferentially evenly distributed stirring spatulas 22 along the rotation axis of the wok 2. The stirring spatulas 22 are arranged along the diameter of the wok 2, and their lower sides are close to the inner wall of the wok 2 and are both designed with an arc shape adapted to the side wall of the wok 2. Each stirring spatulas 22 has an upward-facing and penetrating stirring groove 221 on its upper side. The frame 1 is provided with a driving component 4 for driving the stirring spatulas 22 to rotate circumferentially around the rotation axis of the wok 2.

[0031] The driving component 4 includes a drive shaft 41 located on the lower side of the outside of the wok 2, with its upper end inserted into the wok 2 and rotatably connected to it. Stir-fry spatulas 22 are symmetrically arranged on both sides of the drive shaft 41, with their ends close to each other fixedly connected to the side wall of the drive shaft 41. The stir-fry spatulas 22 are all inclined counterclockwise towards the inside of the wok 2. A fixed frame 42 located on the lower side of the outside of the wok 2 is fixedly connected inside the frame 1. The lower end of the drive shaft 41 passes through the fixed frame 42 and is fitted with a motor 43 fixedly connected to the lower side of the fixed frame 42.

[0032] Reference Figure 2 and Figure 3 The heating assembly 3 includes insulation cotton 31 sleeved and fixedly connected to the outer wall of the wok 2. Multiple arc-shaped electromagnetic strips 32, evenly distributed circumferentially along the outside of the wok 2 and conforming to the shape of the outer wall of the wok 2, are fixedly connected to the side of the insulation cotton 31 away from the wok 2. In this embodiment, eight such strips are used. Multiple horizontal coils 33 are arranged sequentially along the length of each adjacent electromagnetic strip 32 and connecting them. In this embodiment, three coils are used. A stabilizing frame 34 located below the fixing frame 42 is fixedly connected to one side inside the frame 1. An electromagnetic induction heating power supply 35, wirelessly connected to the coils 33, is mounted on the stabilizing frame 34. The electromagnetic induction heating power supply 35 controls the coils 33 to connect to the electromagnetic strips 32, energizing and heating the electromagnetic strips 32.

[0033] The lower side walls of the frame 1 are all sealed, and one side is provided with inspection holes 12 that are adapted to the electromagnetic strip 32 and the motor 43 respectively. The frame 1 is fitted with mounting plates 13 that correspond one-to-one with the inspection holes 12 and seal the inspection holes 12, so that the mounting plates 13 can be removed and the electromagnetic strip 32 and the motor 43 can be inspected.

[0034] Chestnuts are placed in wok 2. Electromagnetic induction heating power supply 35 supplies power to electromagnetic bar 32 through coil 33, thereby heating wok 2 through electromagnetic bar 32. Motor 43 drives stir-fry spatula 22 to rotate around drive shaft 41 and stir-fry chestnuts through drive shaft 41.

[0035] The stir-frying groove 221 on the upper side of the stir-frying spatula 22 makes it easier for chestnuts pushed by the stir-frying spatula 22 to pass over the stir-frying spatula 22 via the stir-frying groove 221, reducing the possibility that some chestnuts are constantly pushed by the stir-frying spatula 22 and are difficult to stir-fry evenly. The tilted stir-frying spatula 22 further facilitates the stir-frying of chestnuts while reducing the possibility that some chestnuts are constantly pushed by the chestnuts and are difficult to stir-fry evenly.

[0036] The insulation cotton 31 keeps the wok 2 warm, reducing the possibility of heat loss. It heats the wok 2 quickly while reducing the possibility of the wok 2 temperature dropping rapidly, thus reducing the adverse effects on the stir-frying of chestnuts.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The upper side of the frame 1 is provided with a horizontal filter screen 5 located above the wok 2. The upper side of the filter screen 5 is provided with multiple layers of horizontal first nano-activated carbon filter cotton 51 arranged in a vertical direction. In this embodiment, it is set to three layers. A filter frame 52 is sleeved and fixedly connected to the outer side of the filter screen 5. An insertion groove 521 is opened on the inner side wall of the filter frame 52, and the edges of the first nano-activated carbon filter cotton 51 are inserted into the insertion groove 521.

[0038] The filter frame 52 is hinged to the inner wall of the frame 1 on the side away from the inspection hole 12. A horizontal fixing plate 6 is fixedly connected to the middle of the filter frame 52 on the side near the inspection hole 12. A vertical screw 61 is fixedly connected to the upper side wall inside the frame 1. An oblong hole 62 is provided on the fixing plate 6 along the length of the fixing plate 6. When the filter frame 52 is set horizontally, the lower end of the screw 61 passes through the oblong hole 62 and is threaded with a nut 63. A secondary filter assembly 7 for further filtering of flue gas is provided on the upper side of the frame 1. The three side walls of the upper end of the frame 1, except for the side near the inspection hole 12, are sealed. A vertical stabilizing plate 14 is provided on the side of the frame 1 near the inspection hole 12. The upper side of the stabilizing plate 14 is hinged to the side wall of the frame 1, which facilitates opening the stabilizing plate 14 and inspecting the filter screen 5 and the first nano-activated carbon filter cotton 51.

[0039] When chestnuts are stir-fried, the generated fumes move upward and pass through the filter screen 5 and the multi-layer first nano-activated carbon filter cotton 51, thereby removing some of the oil fumes from the fumes. The fumes filtered by the filter screen 5 and the first nano-activated carbon filter cotton 51 continue to move to the secondary filter component 7 to further remove oil fumes, so that the fumes after secondary filtration meet the emission standards.

[0040] The filter screen 5 and the first nano-activated carbon filter cotton 51 are installed on the frame 1 via the filter frame 52. When replacement is needed, the nut 63 is turned until the nut 63 disengages from the screw 61, driving the filter frame 52 to rotate along its hinge side. At this time, the screw 61 disengages from the waist-shaped hole 62. The filter frame 52 is rotated until it is easy to remove and replace the first nano-activated carbon filter cotton 51, thus improving the replacement efficiency.

[0041] Reference Figure 2 and Figure 3 The secondary filtration assembly 7 includes an extraction box 71 fixedly connected to the upper part of the frame 1. A connecting hole 15 is provided at the upper end of the frame 1, through which the extraction box 71 communicates with the interior of the frame 1. The extraction box 71 is located on one side of the frame 1, and a filter box 72 with an upper opening is fixedly connected to the other side of the upper end of the frame 1. A centrifugal fan 73 connecting the extraction box 71 and the filter box 72 is installed at the upper end of the extraction box 71. A horizontal sealing plate 74 is provided on the upper side of the filter box 72. An installation edge 721 located within the filter box 72 and along its upper edge is fixedly connected to the upper side of the filter box 72. The installation edge 721 is integrally formed with the filter box 72. The sealing plate 74 overlaps the installation edge 721 and is bonded to the upper side of the installation edge 721, and the sealing plate 74 is fixedly connected to the installation edge 721 by bolts.

[0042] Reference Figure 2 , Figure 3 and Figure 5The sealing plate 74 has two vertically arranged composite dual-barrel filter elements 75 for air purifiers, which are arranged sequentially along the length of the sealing plate 74. The lower ends of the composite dual-barrel filter elements 75 pass through the sealing plate 74 and are inserted into the filter box 72. The upper ends of the composite dual-barrel filter elements 75 are fitted with and fixedly connected to horizontal fixing rings 751. The fixing rings 751 overlap the upper side of the sealing plate 74 and are fixedly connected to the sealing plate 74 with bolts. The upper side of the composite dual-barrel filter elements 75 is fixedly connected to a third nano-activated carbon filter cotton 752 arranged circumferentially along the outer side of the composite dual-barrel filter elements 75.

[0043] Both the extraction box 71 and the filter box 72 are covered with the same mounting frame 76, which is fixedly connected to the upper side of the frame 1. The upper side of the mounting frame 76 is provided with a horizontal second nano-activated carbon filter cotton 761. The upper side of the second nano-activated carbon filter cotton 761 is provided with a pressure frame 762 along the edge of the second nano-activated carbon filter cotton 761. The pressure frame 762 is fixedly connected to the mounting frame 76 by bolts, thereby installing the second nano-activated carbon filter cotton 761 on the mounting frame 76.

[0044] The flue gas drawn from the frame 1 by the centrifugal fan 73 moves to the filter box 72 through the connecting hole 15 and the extraction box 71. At this time, the sealing plate 74 seals the filter box 72, reducing the possibility of oil fumes being discharged from the top of the filter box 72. When filtering the oil fumes in the flue gas, the flue gas first comes into contact with the third nano-activated carbon filter cotton 752 on the outside of the air purifier composite double barrel filter element 75 and some of the oil fumes are intercepted, thus pre-filtering the flue gas that comes into contact with the air purifier composite double barrel filter element 75. After being filtered by the air purifier composite double barrel filter element 75, the flue gas continues to move upward to pass through the mounting frame 76 and is filtered again by the second nano-activated carbon filter cotton 761, so that the filtered flue gas meets the emission standards.

[0045] The sealing plate 74 seals the filter box 72 by bonding and fixing it with bolts, which improves the sealing performance of the gap between the sealing plate 74 and the side wall of the filter box 72 and reduces the possibility of some flue gas escaping through the gap between the sealing plate 74 and the filter box 72.

[0046] The implementation principle of a chestnut stir-frying machine according to an embodiment of this application is as follows: the flue gas moves upward and passes through the filter screen 5 and the multi-layer first nano-activated carbon filter cotton 51, thereby removing some of the oil fumes in the flue gas. The flue gas is drawn from the frame 1 by the centrifugal fan 73 and moved to the filter box 72 through the connecting hole 15 and the air extraction box 71. The flue gas first comes into contact with the third nano-activated carbon filter cotton 752 on the outside of the air purifier composite double barrel filter element 75 and some of the oil fumes are intercepted. Then it is filtered by the air purifier composite double barrel filter element 75. The flue gas filtered by the air purifier composite double barrel filter element 75 continues to move upward to pass through the mounting frame 76 and is filtered again by the second nano-activated carbon filter cotton 761, so that the filtered flue gas meets the emission standards.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
