Description

Technical Field

[0001] The invention relates to the technical field of jam processing, in particular to a fruit jam mixing processing device and a processing method. Background Art

[0002] Jam is a semi-solid or solid food made from fresh fruit. It is washed, peeled, cut, and then sugared and watered. It then undergoes a series of processes, including heating, boiling, stirring, degassing, sterilization, and canning. Traditional jam production relies on mixing pots heated by jackets or heat-conducting rods, with fixed blades or single paddles as the main stirring mechanism. The following technical issues are common during production:

[0003] During traditional stirring and boiling, high-speed paddle rotation or intense steam boiling often results in the generation of numerous bubbles. These bubbles often accumulate on the upper surface of the liquid and appear as dense foam, which can affect the appearance quality and filling volume accuracy of the jam. Furthermore, numerous tiny bubbles suspended in the slurry are unable to rise to the surface in time, forming pores in the finished product, reducing its transparency and taste.

[0004] Furthermore, due to the high viscosity and sugar content of the jam cooking liquid, conventional heating surfaces (especially the tank bottom and lower heating jacket) experience uneven heat exchange with the slurry, which can easily form localized hot spots and lead to sugar caramelization. This caramelization not only produces a bitter taste and darkens the color, but also adheres to the tank walls and paddles, making it difficult to clean and exacerbating quality risks for subsequent batches.

[0005] Therefore, there is an urgent need for a jam boiling and stirring device that can achieve efficient degassing, anti-scorching and rapid switching of production modes to meet the high standards of quality, efficiency and diversity in modern jam production. Summary of the Invention

[0006] The technical problem to be solved by the present invention is that bubbles are easily generated and caramelized during the process of making jam from fruit. A fruit jam mixing and processing device and a processing method are provided, which can prevent carbonization and reduce bubbles when stirring fruit to make jam to solve the above problems.

[0007] The present invention is achieved through the following technical solutions:

[0008] A first aspect of the present invention provides a fruit jam mixing and processing device, comprising a mixing tank, wherein a support cylinder is provided in a through groove on a top surface of the mixing tank, and a cover is provided on the bottom of the support cylinder, and further comprising:

[0009] A stirring mechanism, wherein the stirring mechanism is provided with a main shaft and a stirring member in the stirring tank, wherein the stirring member is provided on the main shaft, and the stirring mechanism is used to stir and mix the materials in the stirring tank and separate bubbles generated after the materials are mixed;

[0010] An elastic diaphragm is provided on the inner bottom surface of the mixing tank; the elastic diaphragm is driven by the main shaft to intermittently expand or contract itself to achieve turning or accommodating of materials;

[0011] The decoking mechanism includes a rotating frame, the top of the rotating frame is arranged parallel to the cover, and the decoking mechanism is used to scrape the inner wall of the mixing tank and can move the material turned over by the elastic diaphragm upward for mixing.

[0012] In the above technical solution, by arranging the stirring mechanism and the decoking mechanism in the same stirring tank, the materials can be fully sheared and squeezed during the stirring and mixing process to squeeze out the bubbles generated after mixing, and the jam attached to the tank wall can be promptly removed through the intermittent scraping of the decoking mechanism to avoid the adhesion of foam and pomace affecting the mixing uniformity and cleanliness, thereby improving processing efficiency and product quality. While the main shaft is operating, the elastic diaphragm intermittently expands and contracts, which can turn over the material at the bottom to prevent coking or squeeze out the bubbles at the bottom.

[0013] Preferably, the rotating frame is rotatably connected to the main shaft, and the rotating frame includes a scraper, a connecting plate and a defoaming plate. The scraper is close to the inner wall of the mixing tank and parallel to the central axis of the mixing tank. The connecting plate is arranged at the top of the scraper, and the connecting plate and the cover are arranged parallel to each other. The stirring member is located in the rotating frame, and the defoaming plate is at the same height as the maximum liquid level of the material in the mixing tank.

[0014] In the above technical solution, the stirring element and the decoking mechanism are synchronously linked. While the stirring element rotates and cuts the fruit, the decoking mechanism can synchronously scrape the inner wall of the stirring tank, thereby improving the mixing uniformity and preventing the jam from coking, and can also clean the inner wall of the stirring tank.

[0015] Preferably, the stirring member is a plurality of stirring blades arranged in an equidistant array around the main shaft, the stirring blades are sheet-shaped, and the plurality of stirring blades are distributed in a spiral shape along the main shaft, and the tail ends of the stirring blades converge toward the central axis of the main shaft.

[0016] In the above technical solution, the spiral rotating blades arranged equidistantly around the main axis cause high shear and forced convection of the material during the mixing process, which not only enhances the cutting and mixing effect of the material, but also helps to squeeze out the bubbles along the tail end of the blade, thereby improving the degassing efficiency and the fineness of the jam texture.

[0017] Preferably, the stirring member is a plurality of pusher pieces and a plurality of cutting pieces distributed in an array around the main shaft, the cutting piece is located below the pusher piece, the top surface of the pusher piece is an inclined surface, and the top surface of the cutting piece is fixedly connected to a cutter.

[0018] In the above technical solution, the pushing piece and the cutting piece are staggered up and down, and a gap is retained between the cutting knife at the top of the cutting piece and the cutting piece. On the one hand, the continuous pushing performance of the fruit is enhanced, and on the other hand, the fruit is sheared through the gap, which not only improves the cutting efficiency but also effectively prevents fruit blockage.

[0019] Preferably, the adjacent cutting blades and pushing blades along the circumferential direction of the main shaft are symmetrically arranged in the upper and lower directions.

[0020] In the above technical solution, the layout in which the axial projections of adjacent cutting blades and pushing blades overlap along the circumferential direction ensures that the pushing and cutting actions occur simultaneously on the same material flow section, improving the synchronization of fruit dispersion and cutting, and making processing more uniform and efficient.

[0021] Preferably, the stirring member is a plurality of spiral cutters, the bottom ends and top ends of the plurality of spiral cutters are connected to the main shaft through a connecting shaft, and the plurality of spiral cutters are distributed in a spiral shape along the axial direction of the main shaft.

[0022] In the above technical solution, the bottom and top ends of several spiral cutters are connected to the main shaft through a connecting shaft and are spirally distributed to form a continuous cutting surface, which enhances the shearing force and fluidity of the fruit and makes the cutting and mixing process smoother and more efficient.

[0023] Preferably, a screen drum is further provided on the outside of the spiral cutter, the bottom and top ends of the screen drum are connected to the main shaft through transition pieces, there are gaps between the screen drum and the spiral blade, the screen drum and the decoking mechanism, and the screen drum and the bottom surface of the stirring tank, and a number of filter holes are opened on the screen drum.

[0024] In the above technical solution, a sieve cylinder is arranged outside the spiral cutter, and the aperture of the filter holes gradually increases in the thickness direction of the sieve cylinder. This design can not only effectively intercept and filter large pieces of fiber and particles during the mixing process, but also prevent the sieve holes from being blocked, thereby ensuring the fineness and continuity of the jam.

[0025] Preferably, a turntable is provided on the main shaft, and the turntable is rotatably connected in the support cylinder. A shift block is coaxially rotatably connected to the main shaft, and a plurality of grooves are provided on the inner circumferential wall of the turntable around the array. The rotation radius of the shift block is equal to the distance from the center of the main shaft to the groove, and the top end of the rotating frame is provided on the outer circumferential wall of the turntable away from the main shaft.

[0026] In the above technical solution, the intermittent drive of the rotating frame is achieved by the turntable and the dial block in conjunction with the groove mechanism, ensuring that the decoking mechanism can scrape the tank wall at a predetermined rhythm during the stirring process, effectively preventing the jam from being coked, while not interfering with the normal rotation of the stirring element.

[0027] Preferably, a limit housing is provided on the main shaft, the limit housing is located in the support tube, a gear set is transmission-connected in the limit housing, the output end of the gear set is connected to a shaft sleeve, and the connecting plate is connected to the shaft sleeve.

[0028] In the above technical solution, the transmission composed of the main shaft and the gear set is utilized so that the rotating frame can work stably at different speeds or different torques, thereby enhancing the reliability and durability of the mechanical transmission.

[0029] Preferably, the rotating frame also includes a tipping hopper, a chute is provided on the scraper, the tipping hopper is slidably connected in the chute through a slider, a protrusion is connected to the side of the tipping hopper away from the stirring mechanism, a rolling groove is provided on the inner wall of the stirring tank, the protrusion is slidably connected in the rolling groove, a plurality of leakage holes are provided on the tipping hopper, and the opening direction of the tipping hopper is tangent to the radial direction of the stirring tank.

[0030] In the above technical solution, the tipping hopper can move up and down during the rotation of the scraper, and can fully mix the materials at the bottom to the top.

[0031] Preferably, a transmission shaft that rotates coaxially with the main shaft is provided on the bottom surface of the mixing tank, an elastic diaphragm is provided between the top end of the transmission shaft and the bottom side wall of the mixing tank, and an accommodating space is formed between the elastic diaphragm and the inner bottom surface of the mixing tank. An eccentric wheel is provided on the transmission shaft, and the distance from one end of the eccentric wheel to the center line of the transmission shaft is much greater than the distance from the other end to the center line of the transmission shaft.

[0032] In the above technical solution, as the main shaft rotates, the transmission shaft drives the eccentric wheel to rotate, and the eccentric wheel contacts the elastic diaphragm to achieve periodic expansion and contraction, which can effectively turn over the material at the bottom to avoid coking.

[0033] Preferably, the end of the cover away from the support cylinder is fixedly connected to the inner peripheral wall of the stirring tank, and the stirring tank is further provided with a feeding port, which is located below the cover.

[0034] In the above technical solution, the cover can block the splashing jam to prevent it from sticking to the top of the mixing tank and coking. The feed port is located below the cover, which is convenient for adding additives and other materials during subsequent processing.

[0035] A second aspect of the present invention provides a fruit jam processing method, which processes jam based on the fruit jam mixing and processing device described in the first aspect of the present invention, comprising:

[0036] S1. Putting the fruit to be processed into the mixing tank, starting the mixing mechanism to mix and cut the fruit to be processed and driving the descorching mechanism to scrape the inner wall of the mixing tank;

[0037] S2, after a preset time period, the stirring mechanism is turned off to obtain jam.

[0038] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0039] 1. The stirring element of the present invention can be of various structural forms and can be flexibly adjusted before processing according to different types of fruits to improve the quality of jam processing. The stirring blades are used to process soft fruits to ensure that the soft fruits do not become mushy and affect the taste. When processing hard fruits, a combination of pusher and cutting blades is used to form a vortex between the dense fruit pulp, thereby improving processing efficiency. When processing hard fruits, a spiral cutter and screen drum are used to quickly chop the dense fruit pulp and process the fibers, thereby improving processing quality.

[0040] 2. The rotating frame of the present invention can prevent the jam from being charred and can also cooperate with the stirring element to scrape off bubbles generated during the fruit splitting process;

[0041] 3. The elastic diaphragm of the present invention can turn over the jam settled on the bottom of the mixing tank when it expands and bulges, thereby preventing it from being scorched. The moving turning hopper can transport the jam at the bottom of the mixing tank to the top, thereby preventing the jam in the mixing tank from being thin in the upper layer and dense in the lower layer. When the turning hopper passes through the raised elastic diaphragm, the above effect can be maximized. When the elastic diaphragm recovers and contracts, the jam sinks, causing the bubbles in the upper layer to collapse and break, thereby achieving a defoaming effect.

[0059] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the examples and accompanying drawings. The exemplary embodiments of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention. It should be noted that the present invention is already in the actual development and use stage.

[0060] Example 1

[0061] like Figures 1 to 4 As shown, this embodiment provides a fruit jam mixing and processing device, including a mixing tank 1, a top surface of the mixing tank 1 is provided with a through groove, a support tube 7 is provided in the through groove, and a cover 71 is provided at the bottom of the support tube 7, and further includes:

[0062] A stirring mechanism is provided on the main shaft 11 and a stirring element in the stirring tank 1. The stirring element is provided on the main shaft 11. The stirring mechanism is used to stir and mix the materials in the stirring tank 1 and to separate bubbles generated after the materials are mixed.

[0063] The elastic diaphragm 8 is arranged on the inner bottom surface of the mixing tank 1; the elastic diaphragm 8 is driven by the main shaft 11 to intermittently expand or contract itself to achieve turning or accommodating the material;

[0064] The decoking mechanism includes a rotating frame 3. The top of the rotating frame 3 is arranged parallel to the cover 71. The decoking mechanism is used to scrape the inner wall of the mixing tank 1 and can take away the materials turned over by the elastic diaphragm 8 and move upward for mixing.

[0065] like Figures 2 to 4 As shown, the rotating frame 3 is rotatably connected to the main shaft 11, and the rotating frame 3 includes a scraper 34, a connecting plate 31 and a defoaming plate 32. The scraper 34 is close to the inner wall of the mixing tank 1 and is parallel to the central axis of the mixing tank 1. The connecting plate 31 is arranged at the top of the scraper 34, and the connecting plate 31 and the cover 71 are arranged in parallel. The defoaming plate 32 is at the same height as the maximum liquid level of the material in the mixing tank 1.

[0066] like Figures 2 to 4 As shown, the stirring member is a plurality of rotating blades arranged in an equidistant array around the main shaft 11. The rotating blades are sheet-shaped and are distributed in a spiral shape along the main shaft 11. The tail ends of the rotating blades converge toward the central axis of the main shaft 11.

[0067] Preferably, there is a distance between the material in the mixing tank 1 and the top surface of the mixing tank 1 to form an exhaust space, and the mixing tank 1 is also provided with an exhaust hole, and a one-way valve is provided in the exhaust hole.

[0068] First of all, it should be noted that when making jam, fruits of different hardness have different requirements, such as soft fruits, including but not limited to strawberries, blueberries, bananas, and ripe fruits such as ripe peaches; medium-hard fruits, including but not limited to kiwis, apples, pears, etc.; hard fruits, including but not limited to pineapples, citrus fruits with skins, and hard and crisp fruits; soft fruits usually require low-speed stirring and do not require high extrusion shear force; medium-hard fruits usually require higher speeds than soft fruits; hard fruits, due to their firm flesh, usually require higher speeds and stronger crushing strength for stirring.

[0069] This embodiment is used for processing soft fruits: the top surface of the mixing tank 1 should be provided with an openable and closable feeding port, which is located on one side of the through groove on the top surface. The bottom of the mixing tank 1 is provided with an openable and closable feeding port. Before the support cylinder 7 is installed in the through groove, the pre-treated fruit to be processed and the processing water are put into the mixing tank 1 through the feeding port or the through groove. The feeding port is closed and the driving member is started. The driving member can be a power device such as a motor. The output end of the driving member is connected to the main shaft 11 for driving the main shaft 11 to rotate together. The plurality of stirring blades 21 rotate synchronously with the main shaft 11 to achieve stirring and squeezing of the soft fruit.

[0070] The plurality of stirring blades 21 are of sheet-like structure and are distributed in a spiral shape. The sheet-like stirring elements can prevent the soft fruits from being crushed into a paste and affecting the taste of the jam when stirring the soft fruits, and the bottom ends of the plurality of stirring blades 21 are converged toward the axis of the main shaft 11, which can effectively gather the unbroken soft fruits on the outside of the stirring blades 21 to the center, and turn them into jam through the rotation and squeezing of the stirring blades 21.

[0071] It should be noted that when the fruit is processed into jam, a certain amount of processing water will be added and the fruit in the mixing tank 1 will be heated. Therefore, the whole fruit will produce bubbles to varying degrees after being cut or squeezed, and the fruit will produce natural pectin after being crushed, which will increase the persistence of bubbles and foam. If the bubble content in the jam is high, it will affect the appearance and taste of the finished jam. Moreover, when the finished jam is sealed and canned, the bubbles will remain in the bottleneck or bottle mouth, affecting the sealing of the can. In severe cases, the oxygen in the bubbles will cause the jam to oxidize prematurely, reducing its color and taste, which is not conducive to long-term storage.

[0072] Preferably, the spirally distributed stirring blades 21 will also gather bubbles to the center when moving the fruit on the periphery to the center. The gathered bubbles are uniformly broken and split by the stirring blades 21. After the bubbles are broken and split, they rise to the exhaust space of the stirring tank 1 and the gas is discharged to the outside through the one-way valve.

[0073] Example 2

[0074] like Figures 2 to 4 As shown, a turntable 5 is provided on the main shaft 11, and a shift block 4 is connected to the main shaft 11 for coaxial rotation. A plurality of grooves 51 are provided on the inner peripheral wall of the turntable 5 around the array. The rotation radius of the shift block 4 is equal to the distance from the center of the main shaft 11 to the groove 51. The top end of the rotating frame 3 is provided on the outer peripheral wall of the turntable 5 away from the main shaft 11.

[0075] When processing soft fruits as in Example 1, the decoking mechanism will also operate along with the rotation of the main shaft 11 to prevent the jam adhering to the inner wall of the mixing tank 1 from caramelizing under the high temperature and high sugar content environment in the mixing tank 1.

[0076] It should be noted that this embodiment is used to process the soft fruits in Example 1. The stirring mechanism and the descorching mechanism usually do not require a high rotation speed. When the rotation speed is not high, the jam will not splash upwards obviously. Therefore, Figures 2 to 4 As shown, the mixing tank 1 is not provided with a cover 71, and the rotating frame 3 is U-shaped as a whole. The bottom of the rotating frame 3 is used to drive the jam at the bottom to turn over, and the defoaming plate 32 is used to scrape the top layer of jam. The connecting plate 31 at the top of the rotating frame 3 is mainly used to connect the turntable 5 in this embodiment, and the scraper 34 is used to scrape the inner wall of the mixing tank 1.

[0077] The cam 5 is provided with a plurality of through holes 51 on the top of the main shaft 11, and the cam 5 is provided with a plurality of through holes 51 on the top of the main shaft 11. The cam 5 is provided with a plurality of through holes 51 on the top of the main shaft 11, and the cam 5 is provided with a plurality of through holes 51 on the top of the main shaft 11. The cam 5 is provided with a plurality of through holes 51 on the top of the main shaft 11, and the cam 5 is provided with a plurality of through holes 51 on the top of the main shaft 11. The cam 5 is provided with a plurality of through holes 51 on the top of the main shaft 11, and the cam 5 is provided with a plurality of through holes 51 on the top of the main shaft 11. The force of the rotation of the dial block 4 forms a circumferential thrust through the groove 51 of the turntable 5, pushing the groove 51, forcing the turntable 5 to rotate, thereby driving the rotating frame 3 to rotate. When the rotating frame 3 rotates, it will scrape the mixing tank 1 to prevent the jam close to the mixing tank 1 from adhering to the inner wall for a long time and coking. In addition, the rotating frame 3 can also play the effect of stirring soft fruits. Since the rotating frame 3 is located on the outside of the stirring blade 21, it can also gather the fruits on the outside of the stirring blade 21 inward, thereby improving the processing efficiency. The movement of the turntable 5 depends on the cooperation of the dial block 4 and the groove 51. The rotation of the dial block 4 can make the turntable 5 rotate intermittently, which can prevent the excessively fast stirring mechanism from damaging the soft fruits and affecting the taste of the jam.

[0078] The maximum amount of fruit put in a single process should be such that when making jam, the maximum liquid level is flush with the top surface of the rotating frame 3; when the rotating frame 3 rotates, it can push the top surface of the jam to break the bubbles floating on the top surface of the jam.

[0079] Example 3

[0080] like Figures 5 to 10 As shown, the stirring member is a plurality of pusher pieces 22 and a plurality of cutting pieces 23 distributed in an array around the main shaft 11. The cutting piece 23 is located below the pusher piece 22. The top surface of the pusher piece 22 is an inclined surface. The top surface of the cutting piece 23 is fixedly connected to a cutter 231.

[0081] like Figures 5 to 10 As shown, adjacent cutting blades 23 and pushing blades 22 along the circumferential direction of the main shaft 11 are symmetrically arranged up and down.

[0082] Specifically, this embodiment is used to process medium-hard nuts as described in Example 1, and the difference in displacement lies in the different structure of the stirring member and the different arrangement of the rotating frame 3 and the main shaft 11.

[0083] Compared with soft fruits, medium-hard fruits have relatively firm flesh. The stirring members in this embodiment are a pushing piece 22 and a cutting piece 23 symmetrically arranged up and down. When the main shaft 11 starts to rotate, the medium-hard fruits are cut and broken by the cutter 231 on the cutting piece 23 during the rotation. The top of the pushing piece 22 is an inclined surface, with one side high and the other side low. In the process of following the rotation of the main shaft 11, the inclined surface of the pushing piece 22 can achieve a pushing effect, which can fully mix the fruits in the stirring tank 1.

[0084] Preferably, the pushing piece 22 and the cutting piece 23 symmetrically arranged above and below are inclined to each other, the higher side of the pushing piece 22 is inclined upward, and the cutting blade 231 of the cutting piece 23 is inclined downward, and the inclination direction is close to the higher side of the height direction of the pushing piece 22. During the stirring process, the cutting blade 231 of the cutting piece 23 cuts the fruit downward, and the pushing piece 22 pushes the fruit upward, forming an upper and lower convection effect, which can better chop medium and hard fruits into jam.

[0085] Regarding the bubbles generated during the production of fruit jam in this embodiment: the pushing piece 22 and the cutting piece 23 are symmetrically arranged as described above, and there is a gap between the two. During the rotation process, a vortex is formed between the two, which guides the bubbles to be attracted to the cutting piece 23 or the pushing piece 22. The bubbles guided to the cutting piece 23 will be split and broken by the cutter 231, and the bubbles falling on the pushing piece 22, like the principle of the rotating frame 3 in Example 2, rise to the top surface of the jam. The continuously rotating pushing piece 22 can flip the top surface of the jam while splitting and breaking the bubbles on the top surface of the jam.

[0086] Example 4

[0087] like Figures 11 to 13 As shown, the stirring members are a plurality of spiral cutters 24 , the bottom ends and top ends of the plurality of spiral cutters 24 are connected to the main shaft 11 through a connecting shaft, and the plurality of spiral cutters 24 are distributed in a spiral shape along the axial direction of the main shaft 11 .

[0088] like Figures 11 to 13 As shown, a sieve drum 25 is further provided on the outside of the spiral cutter 24. The bottom and top ends of the sieve drum 25 are connected to the main shaft 11 through transition pieces. There are gaps between the sieve drum 25 and the spiral blade, the sieve drum 25 and the decoking mechanism, and the sieve drum 25 and the bottom surface of the mixing tank 1. A plurality of filter holes are opened on the sieve drum 25.

[0089] Specifically, this embodiment is used to process nuts as described in Example 1, and the difference in displacement lies in the different structure of the stirring member and the different arrangement of the rotating frame 3 and the main shaft 11.

[0090] In this embodiment, when processing hard fruits, the hard fruits are cut by the spiral cutter 24. The spiral cutter 24 cuts the fruits under high-speed rotation, which can quickly crush the pulp and fibers to obtain delicate jam.

[0091] A sieve drum 25 connected to the main shaft 11 is provided on the outer side of the spiral cutter 24. When the spiral cutter 24 rotates, centrifugal force is generated to throw the pulp onto the side wall of the sieve drum 25, and the bubbles contained in the jam can be split and broken when passing through the filter holes of the sieve drum 25; there is a distance between the sieve drum 25 and the mixing tank 1, forming an inner cylinder structure. When the spiral cutter 24 throws the pulp onto the sieve drum 25, most of the pulp flows along the bottom surface of the sieve drum 25 to the mixing tank 1, and a small amount of pulp passes through the filter holes. The pulp located between the sieve drum 25 and the mixing tank 1 will return to the sieve drum 25 from the top surface of the sieve drum 25 under the action of the spiral cutter 24 for secondary cutting, stirring and defoaming, thereby improving the quality of the jam.

[0092] Example 5

[0093] like Figures 5 to 11 As shown, a limit housing 63 is provided on the main shaft 11, and a gear set is connected in a transmission manner in the limit housing 63. The gear set includes a first bevel gear 61, a transition bevel gear and a second bevel gear 62 that are meshed with each other. The first bevel gear 61 is fixedly connected to the main shaft 11, and the transition bevel gear is respectively connected in transmission to the first bevel gear 61 and the second bevel gear 62. The bottom surface of the second bevel gear 62 is provided with a fixed sleeve rotatably connected to the limit housing 63, the middle part of the second bevel gear 62 is connected to the shaft sleeve, and the connecting plate 31 is connected to the shaft sleeve.

[0094] The decoking mechanism in this embodiment is different from that in embodiment 2, and the decoking mechanism in this embodiment is mainly used in the stirring member in embodiments 3 and 4. The support cylinder 7 in this embodiment is provided with a bottom plate relative to embodiment 2 for accommodating the limiting housing 63. Figure 5 and Figure 6 As shown, the first bevel gear 61, the transition bevel gear and the second bevel gear 62 are connected to each other in a transmission manner. The bottom surfaces of the second bevel gear 62 and the transition bevel gear are provided with a fixed sleeve that is rotatably connected to the limit housing 63. The middle part of the second bevel gear 62 is connected to a shaft sleeve, which is located on the outside of the main shaft 11. The connecting plate 31 of the rotating frame 3 is connected to the shaft sleeve to realize transmission.

[0095] Compared with the soft fruits processed in Example 1, the medium-hard fruits and hard fruits processed in Examples 3 and 4 require a relatively high rotation speed. The intermittent rotating frame 3 in Example 2 is not suitable for the case of a high rotation speed. In this embodiment, the main shaft 11 drives the first bevel gear 61 and the stirring member to rotate. The first bevel gear 61 transmits power to the second bevel gear 62 through the transition bevel gear. The second bevel gear 62 drives the rotating frame 3 to rotate, and the direction of the stirring member is opposite to that of the rotating frame 3.

[0096] The rotating frame 3 in this embodiment can not only achieve the degassing effect and the effect of preventing caramelization in Example 3, but also has the following advantages:

[0097] When used in Example 3, the pulp and bubbles can be brought in by the cutting blades 23 for cutting and crushing more quickly, thereby enhancing the stirring effect and the bubble crushing effect; when used in Example 4, the rotating frame 3 located on the outside of the sieve cylinder 25 and rotating in the opposite direction can achieve a shearing effect, thereby preventing the pulp from staying at the filter holes of the sieve cylinder 25 for a long time and causing blockage. In addition, combined with the centrifugal force generated by the spiral cutter 24, a double degassing effect is formed, wherein the spiral cutter 24 removes bubbles inside the sieve cylinder 25, and the rotating frame 3 removes bubbles outside the sieve cylinder 25, thereby further improving the quality of the jam.

[0098] Example 6

[0099] A fruit jam processing method, based on a fruit jam mixing and processing device of Examples 1-5, comprises:

[0100] S1. Put the fruit to be processed into the mixing tank 1, start the mixing mechanism to mix and cut the fruit to be processed and drive the descorching mechanism to scrape the inner wall of the mixing tank 1;

[0101] S2, after the preset time, the stirring mechanism is turned off to obtain jam.

[0102] Before the fruit to be processed is put into the mixing tank 1, the following steps are also included:

[0103] The fruits to be processed are pre-treated, and the pre-treatment includes one or more of cleaning, disinfection, peeling, core removal, and seed removal.

[0104] During the process of executing S1 , one or more of sugar, acid, and additives are added into the mixing tank 1 .

[0105] Specifically, the fruits are pre-processed according to the different fruits currently required, and then put into the mixing tank 1. The mixing tank 1 should be provided with a driving member, which controls the rotation of the main shaft 11. When the fruits are processed into jam, sugar, acid, and additives can be added. The added sugar can be white sugar, and the acid can be lemon juice, vitamin C powder, etc.; the additives can be pectin, spices, preservatives, etc.

[0106] Example 7

[0107] like Figures 5 to 9As shown, the rotating frame 3 also includes a tipping hopper 33, a chute is provided on the scraper 34, the tipping hopper 33 is slidably connected in the chute through a slider, a protrusion is connected to the side of the tipping hopper 33 away from the stirring mechanism, a rolling groove is provided on the inner wall of the mixing tank 1, the protrusion is slidably connected in the rolling groove, a plurality of leakage holes are provided on the tipping hopper 33, and the opening direction of the tipping hopper 33 is tangent to the radial direction of the mixing tank 1.

[0108] like Figures 5 to 13 As shown, the bottom surface of the mixing tank 1 is provided with a transmission shaft 81 that rotates coaxially with the main shaft 11, and an elastic diaphragm 8 is provided between the top end of the transmission shaft 81 and the bottom side wall of the mixing tank 1. A accommodating space is formed between the elastic diaphragm 8 and the inner bottom surface of the mixing tank 1, and an eccentric wheel 82 is provided on the transmission shaft 81. The distance from one end of the eccentric wheel 82 to the center line of the transmission shaft 81 is much greater than the distance from the other end to the center line of the transmission shaft 81.

[0109] like Figures 5 to 13 As shown, one end of the cover 71 away from the support tube 7 is fixedly connected to the inner peripheral wall of the mixing tank 1 . The mixing tank 1 is also provided with a feeding port, which is located below the cover 71 .

[0110] When the descorching mechanism described in Examples 2 and 5 is in operation, it not only prevents the jam from scorching, but also evenly mixes the crushed fruit fibers and particles and removes any bubbles or foam from the jam. It should be noted that when fruit is made into jam, water and other ingredients are added. Therefore, after the fruit is crushed, its fibers and particles settle and are unable to mix with the lighter material on the top layer.

[0111] When the main shaft 11 rotates, it drives the transmission shaft 81 to rotate together. Preferably, the inner bottom surface of the mixing tank 1 is fixedly connected to a fixed cylinder, and the transmission shaft 81 rotates in the fixed cylinder. An annular groove is provided on the outer peripheral wall of the main shaft 11 near the transmission shaft 81, and a rotation groove is provided on the upper and lower bottom surfaces of the annular groove. A support platform is fixedly connected to the inner peripheral wall of the mixing tank 1 near the bottom surface, and the bottom end of the elastic diaphragm 8 is fixedly connected to the support platform. The top of the elastic diaphragm 8 is fixedly connected to a bearing ring, and the bearing ring is rotatably connected in the annular groove and the rotation groove. When the main shaft 11 rotates, since the bottom of the elastic diaphragm 8 is fixed, the bearing ring will play a transition role in the rotation groove, and the elastic diaphragm 8 itself will not rotate. The elastic diaphragm 8 should be in a contracted state under normal circumstances.

[0112] The transmission shaft 81 is located below the elastic diaphragm 8, and an eccentric wheel 82 is fixedly mounted on the outer peripheral wall. When the transmission shaft 81 rotates with the main shaft 11, the elastic diaphragm 8 is driven to rotate. The elastic diaphragm 8 is pushed by the eccentric wheel 82 and bulges toward the inside of the mixing tank 1. Preferably, the end of the eccentric wheel 82 in contact with the elastic diaphragm 8 should be covered with a flexible sleeve to avoid scratching the elastic diaphragm 8. The elastic diaphragm 8 can also be replaced after completing multiple processes and reaching its service life; the bulged elastic diaphragm 8 can squeeze the material at the bottom upward or toward the inner wall of the mixing tank 1, and during the squeezing, the bubbles in the jam can be broken or split. At the same time, since the jam contains a large amount of fiber particles, the elastic diaphragm 8 can flip the fiber particles to the top for mixing, avoiding long-term accumulation and coking at the bottom, and can also flip the material in the dead corner at the bottom of the mixing tank 1. At the same time, it can be fully mixed with the jam with a higher water content above, without causing a thin upper layer and a dense lower layer.

[0113] After the eccentric wheel 82 leaves the area, the raised elastic diaphragm 8 gradually recovers and contracts, and the jam at that location sinks instantly. The bubbles or foam at the top layer of the jam, that is, at the maximum liquid level, will collapse or burst instantly due to the loss of jam support, which can also achieve the effect of removing bubbles.

[0114] In addition, as mentioned in the above-mentioned multiple embodiments, the rotating frame 3, in this embodiment, includes a scraper 34, a connecting plate 31, a defoaming plate 32 and a tipping hopper 33. The connecting plate 31 is fixedly connected to the shaft sleeve or the outer peripheral wall of the turntable 5 as a connection. The defoaming plate 32 is arranged horizontally. When the tipping hopper 33 rotates following the scraper 34, the rolling groove on the mixing tank 1 acts as a guide, and the protrusion drives the tipping hopper 33 to move up and down along the slide groove along the rolling groove.

[0115] When the rotating frame 3 rotates, when the tipping hopper 33 is at the lowest point, especially when the tipping hopper 33 passes the raised elastic diaphragm 8, the opening of the tipping hopper 33 receives the jam turned up by the elastic diaphragm 8 and continues to rotate with the rotating frame 3. The path of the tipping hopper 33 in the height direction is a cycle of rising, falling, and rising. The fiber particles settled at the bottom are driven upward by the tipping hopper 33 and gradually fall into the mixing tank 1 through the leakage holes on the tipping hopper 33, so as to achieve the effect of mixing the fiber particles settled at the bottom with the jam above. Firstly, it can avoid the situation that the upper layer of jam is thin and the lower layer is dense. Secondly, it can be combined with the elastic diaphragm 8 to mix the fiber particles settled at the bottom with the jam above. The diaphragm 8 cooperates to prevent the fiber particles at the bottom of the mixing tank 1 from staying for a long time and coking to the greatest extent. Thirdly, the overall movement mode of the tipping hopper 33 is a cycle of rotational rise and rotational fall. During the movement, the bubbles in the bottom and middle layers of the jam can be taken away and risen, accelerating the bursting of the bubbles. Fourthly, when the tipping hopper 33 collects the jam, it will contain large-sized fruits that have not been crushed and broken fiber particles. The fiber particles fall through the leakage holes during the movement of the tipping hopper 33, and the large-sized fruits will be carried away by the eddy current generated by the stirring mechanism in the middle during the movement of the tipping hopper 33 to achieve crushing, thereby further improving the stirring effect.

[0116] As mentioned in Example 2, the rotating frame 3 can scrape the bubbles above the maximum liquid level of the jam. In this embodiment, the scraping is performed by the defoaming plate 32. When the bubbles are at the top, they will break and release gas. However, the outside of the bubbles contains jam. Therefore, when the bubbles break, the jam may splash out. The cover 71 can prevent the jam from splashing to the top of the mixing tank 1. Since there is no jam on the top of the mixing tank 1, if the jam splashes on the surface, it will easily coke at high temperature, affecting the quality of the jam in the mixing tank 1. The connecting plate 31 is arranged parallel to the cover 71, which can scrape the splashed jam on the cover 71 and make it fall to avoid coking.

[0117] For example, the decoking mechanisms and stirring elements in Examples 1 to 5, all stirring elements, including the surfaces of the stirring blades 21, the pusher 22, the cutting blade 23, the spiral cutter 24 and the screen drum 25, can be provided with spiral grooves with upward trajectories. Since bubbles mostly appear in the upper layer, the upper-middle layer and the middle layer, when the stirring element rotates, the spiral grooves can provide a certain guiding effect, floating the bubbles to the top, splitting and breaking them, and further enhancing the defoaming effect.

[0118] It should also be noted that during the jam processing, required additives and other additional materials may be added again. Due to the obstruction of the cover 71, the top feeding port for feeding fruit cannot smoothly add the additives to the jam being stirred. At this time, the additives can be added through the feeding port. The height of the feeding port should be below the cover 71 and above the maximum liquid level of the jam. A valve is provided to prevent leakage, so that suitable additives can be added to the mixing tank 1 during the jam processing.

[0119] The specific implementation methods described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific implementation method of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
