Description

Technical Field

[0001] This invention relates to the field of candied fruit soaking technology, and more specifically to a processing device for candied fruit production. Background Technology

[0002] Candied fruit is a traditional food made primarily from fruits and vegetables, preserved with sugar or honey. Its typical processing steps include: raw material pretreatment, hardening and color protection, pre-cooking, sugaring, drying, and packaging. Sugaring is the core process, aiming to allow sugar to fully penetrate the fruit and vegetable tissues through osmosis, displacing some of the water, thereby reducing water activity, achieving long-term preservation, and imparting its unique sweet flavor and full texture.

[0003] In industrial production, vacuum sugar infiltration technology is often used, which utilizes a negative pressure environment to accelerate the penetration of sugar solution into the intercellular spaces and interior of fruits and vegetables, thereby improving sugar production efficiency and uniformity. However, in conventional atmospheric pressure sugar production, the raw materials of fruits and vegetables are placed directly on the surface of the sugar solution without effective stirring or turning measures, resulting in insufficient contact with the sugar solution and problems such as uneven sugar penetration and inconsistent color and sweetness of the finished product.

[0004] To address the aforementioned issues, there is an urgent need to develop a processing device for candied fruit production. This device should be able to actively break the static state of the raw materials and promote full and dynamic contact between the fruit and vegetable raw materials and the sugar solution through mechanical movement, thereby improving the uniformity and process stability of the sugaring process. Summary of the Invention

[0005] In view of the problems raised in the background art, the present invention provides a processing device for making candied fruit to solve the problems, and the present invention will be further described below.

[0006] A processing device for making candied fruit includes a support frame, a soaking tank mounted on top of the support frame, a detachable sealing cover connected to the top of a stirring tank, a positioning frame mounted on the bottom of the support frame, an electric push rod mounted on the positioning frame, a pusher connected to the output end of the electric push rod, a foldable liquid storage bladder mounted on the top surface of the pusher, the foldable liquid storage bladder being connected to the inner cavity of the soaking tank via a pipeline, a shaking mechanism provided in the inner cavity of the soaking tank for shaking the raw materials as a whole, a stirring mechanism provided in the inner cavity of the soaking tank for stirring the raw materials to ensure that the raw materials are fully immersed in the sugar solution, and a drive mechanism provided on the soaking tank for driving the shaking mechanism and the stirring mechanism.

[0007] Preferably, the shaking mechanism includes two symmetrically rotating shafts that are connected to the soaking tank, and a turning frame located in the inner cavity of the soaking tank is fixed between the two rotating shafts. A filter tank is placed on the turning frame, and the filter tank has a number of evenly distributed filter holes.

[0008] Preferably, the top of the filter barrel is fitted with a cover plate.

[0009] Preferably, the stirring mechanism includes a rotating rod that is connected to the filter barrel, and a multi-blade silicone stirring element is provided on the outer periphery of the rotating rod, with the multi-blade silicone stirring element located below the cover plate.

[0010] Preferably, the drive mechanism includes two connecting frames symmetrically fixed to the push frame, each connecting frame having a T-shaped guide frame fixed to its top, the T-shaped guide frame having a transverse groove, and each rotating shaft having a crank fixed to it, the crank slidingly engaging with the adjacent transverse groove.

[0011] Preferably, gears are keyed to both ends of the rotating rod, and two symmetrically distributed semi-gear rings are fixed to the inner cavity of the soaking tank, with each semi-gear ring corresponding to and meshing with a gear.

[0012] Preferably, the outer wall of the soaking tank is connected to a rotating ring, and two symmetrically distributed rotating frames are fixed to the bottom of the rotating ring. Each rotating frame has an inclined groove. Two symmetrically distributed limiting frames are fixed to the support frame, and the limiting frames and rotating frames correspond one-to-one. Each limiting frame has a vertical groove, and a sliding block slides in the vertical groove. The top of the sliding block slides in the corresponding inclined groove. A compression spring is provided between the sliding block and the limiting frame. The working end of the sliding block has an inclined surface, which is used to cooperate with the bottom of the push frame to achieve mechanical locking of the push frame in the high position.

[0013] Preferably, the bottom of the push frame is provided with a hollow sealed column, the output end of the electric push rod is fixedly connected with a sealing ring, the sealing ring is slidably connected to the inner cavity of the sealed column, the push frame is provided with a water hole, and the foldable liquid storage bladder is connected to the inner cavity of the sealed column through the water hole.

[0014] Preferably, a jetting device is connected through the soaking tank, and the sealed column and the jetting device are connected by a delivery hose.

[0015] Beneficial effects: This device is driven by an electric push rod, which pushes the frame, T-shaped guide frame and crank in a sliding groove, so that the filter barrel swings and causes the raw materials to tumble; at the same time, the swing of the filter barrel drives the gear to roll along the half gear ring, so that the rotating rod rotates and drives the multi-bladed silicone agitator to rotate. The silicone agitator continuously disturbs the liquid surface area, effectively breaking the static state of the raw materials, so that the raw materials can fully contact the sugar solution and significantly improve the consistency of sugar penetration.

[0016] The retraction of the electric push rod causes the sealing ring to descend, creating a localized negative pressure cavity above the sealing ring. This allows the residual sugar solution in the folded storage bladder to be drawn into the sealed column cavity through the water hole. The solution is then sprayed into the soaking tank via the delivery hose, causing strong disturbance to the liquid inside the tank. This enhances the mass transfer between the sugar solution and the raw materials, effectively improving the mixing uniformity and penetration efficiency during the sugar production process.

Detailed Implementation

[0024] Next, combine Figures 1-6 A specific embodiment of the present invention will be described in detail below.

[0025] refer to Figure 1 and Figure 2 A processing device for making candied fruit includes a support frame 1, a soaking tank 11 mounted on the top of the support frame 1, a detachable cap 12 connected to the top of the stirring tank 11, a positioning frame 2 mounted on the bottom of the support frame 1, an electric push rod 21 mounted on the positioning frame 2, a push frame 211 connected to the output end of the electric push rod 21, a foldable liquid storage bladder 22 mounted on the top surface of the push frame 211, the foldable liquid storage bladder 22 being connected to the inner cavity of the soaking tank 11 via a pipeline, a shaking mechanism provided in the inner cavity of the soaking tank 11 for shaking the raw materials as a whole, a stirring mechanism provided in the inner cavity of the soaking tank 11 for stirring the raw materials to ensure that the raw materials are fully immersed in the sugar solution, and a driving mechanism provided on the soaking tank 11 for driving the shaking mechanism and the stirring mechanism to operate.

[0026] refer to Figure 3 and Figure 4 The shaking mechanism includes two symmetrically mounted rotating shafts 34 connected to the soaking tank 11. A turning frame 23 is fixed between the two rotating shafts 34 and located inside the soaking tank 11. A filter tank 13 is placed on the turning frame 23. The filter tank 13 has several evenly distributed filter holes to facilitate the free flow of sugar solution. In use, the fruit and vegetable raw materials are placed in the filter tank 13, and the sugar solution is injected into the soaking tank 11, achieving liquid exchange between the inside and outside through the filter holes. When the rotating shafts 34 rotate, they drive the turning frame 23, causing the filter tank 13 to swing back and forth inside the soaking tank 11, promoting the tumbling of the internal raw materials and enhancing the uniformity of sugar solution penetration.

[0027] refer to Figure 2 The top of the filter barrel 13 is connected to a cover plate 14. When the cover plate 14 is opened, the raw material is put into the filter barrel 13, and then the cover plate 14 is closed to limit the height of the raw material in the filter barrel 13.

[0028] refer to Figure 3 The stirring mechanism includes a rotating rod 45 that is connected to the filter bucket 13. The rotating rod 45 is provided with a multi-blade silicone stirring element 46 on its outer periphery. The multi-blade silicone stirring element 46 is located below the cover plate 14. The silicone material is soft, which can avoid damaging the fruit and vegetable tissues during the stirring process. At the same time, it can effectively disturb the area near the liquid surface, break the static state of the raw materials, and make them soak in the sugar solution.

[0029] refer to Figure 2 The drive mechanism includes two connecting frames 4 symmetrically fixed to the push frame 211. Each connecting frame 4 has a T-shaped guide frame 41 fixed to its top. The T-shaped guide frame 41 has a transverse groove 411. Each rotating shaft 34 has a crank 42 fixed to it. The crank 42 slides with the adjacent transverse groove 411.

[0030] Both ends of the rotating rod 45 are keyed to gears 44. The inner cavity of the soaking tank 11 is fixed with two symmetrically distributed semi-gear rings 43, which correspond one-to-one with and mesh with the gears 44.

[0031] In the initial state, the filter bucket 13 is in a horizontal equilibrium position, the gear 44 is engaged with the half-gear ring 43, the crank 42 is at the outermost limit position of the transverse groove 411, the electric push rod 21 is in the retracted state, and the push frame 211 is in the low position. At this time, the sealing cover 12 is opened, and the fruit and vegetable raw materials are put into the filter bucket 13. The sugar solution is injected into the soaking bucket 11, and some of the sugar solution is also filled into the folded liquid storage bag 22.

[0032] As the pusher 211 moves upward, the connecting frame 4 and the T-shaped guide frame 41 rise synchronously. Since the crank 42 is slidably engaged in the transverse groove 411, the vertical movement of the T-shaped guide frame 41 is converted into the rotational movement of the crank 42 through the transverse groove 411, which in turn drives the rotating shaft 34 to rotate, causing the filter bucket 13 to swing inside the soaking bucket 11, thereby realizing the overall tumbling of the raw materials and the dynamic exchange of sugar solution.

[0033] At the same time, the swing of the filter barrel 13 causes the rotating rod 45 to swing as a whole, causing the gear 44 to roll along the fixed half gear ring 43. Since the half gear ring 43 is an arc-shaped incomplete gear structure, the gear 44 rotates when it rolls on its surface, thereby driving the rotating rod 45 to rotate, which in turn drives the multi-blade silicone agitator 46 to gently stir the raw materials near the liquid surface in the filter barrel 13, breaking the static state of the raw materials.

[0034] Driven by the electric push rod 21, the linkage of the connecting frame 4, crank 42, and rotating shaft 34 causes the filter bucket 13 to swing inside the soaking bucket 11. Through the linkage of the rotating rod 45, gear 44, and half gear ring 43, the multi-blade silicone agitator 46 rotates, realizing the synergistic effect of dynamic sugar solution replenishment, overall raw material tumbling, and local anti-floating agitation. This significantly improves the uniformity of sugar production and process efficiency, and solves the problem of insufficient soaking caused by the static placement of raw materials in the traditional soaking process.

[0035] refer to Figure 4 and Figure 5 The outer wall of the soaking tank 11 is connected to a rotating ring 3. Two symmetrically distributed rotating frames 31 are fixed to the bottom of the rotating ring 3. Each rotating frame 31 has an inclined groove. Two symmetrically distributed limiting frames 32 are fixed to the support frame 1. The limiting frames 32 and the rotating frames 31 correspond one-to-one. The limiting frames 32 have vertical grooves. A sliding block 33 slides in the vertical groove. The top of the sliding block 33 slides in the corresponding inclined groove. A compression spring 35 is provided between the sliding block 33 and the limiting frame 32. The working end of the sliding block 33 has an inclined surface. This inclined surface is used to cooperate with the bottom of the push frame 211 to realize the mechanical locking of the push frame 211 in the high position.

[0036] When the pusher 211 moves to the predetermined working height, the operator applies external force to rotate the rotating ring 3, causing the two rotating frames 31 to rotate synchronously. Since the inclined groove is slidably connected to the top of the sliding block 33, the rotational motion of the rotating frame 31 is converted through the inclined groove into the horizontal movement of the sliding block 33 towards the axis of the soaking tank 11. Simultaneously, the sliding block 33 is constrained by the vertical groove on the limiting frame 32, and it also moves along the vertical groove (i.e., towards the axis of the soaking tank 11). During this process, the inclined surface of the sliding block 33 gradually moves upward and engages with the bottom of the pusher 211, forming a support limit; the compression spring 35 is then compressed. Under the combined guidance of the inclined groove and the constraint of the vertical groove, the sliding block 33 maintains a stable posture, and its inclined surface continuously presses against the bottom surface of the pusher 211, thereby achieving reliable locking of the pusher 211 in the high position.

[0037] refer to Figure 6 The bottom of the push frame 211 is provided with a hollow sealed column 5. The output end of the electric push rod 21 is fixed with a sealing ring 38. The sealing ring 38 is slidably connected to the inner cavity of the sealed column 5 to form a piston-type sealing structure. The push frame 211 is provided with a water hole 51. The foldable liquid storage bladder 22 is connected to the inner cavity of the sealed column 5 through the water hole 51.

[0038] In the initial state, the sealing ring 38 is located directly below the water hole 51 and tightly seals its bottom opening, thus closing the flow channel between the folded liquid storage bladder 22 and the sealed column 5, preventing the sugar solution from entering the inner cavity of the sealed column 5.

[0039] A jetting device 37 is connected through the soaking tank 11, and the sealed column 5 and the jetting device 37 are connected by a delivery hose 36.

[0040] During the upward movement, the electric push rod 21 drives its output end to move upward, causing the sealing ring 38 to move upward synchronously, thereby pushing the entire push frame 211 to rise. During this process, the sealing ring 38 always blocks the bottom of the water hole 51, and the folded liquid storage bladder 22 is pressurized, directly discharging the sugar solution stored inside into the soaking tank 11, thereby achieving liquid level increase and initial disturbance.

[0041] When the pusher 211 rises to the predetermined working height, its bottom surface is limited and fixed by the sliding block 33. Subsequently, the output end of the electric push rod 21 begins to move downward, driving the sealing ring 38 to move downward within the sealed column 5. Since the water hole 51 is no longer blocked by the sealing ring 38, a local negative pressure cavity is formed in the area above the sealing ring 38 within the sealed column 5. Under this negative pressure, the residual sugar solution in the folded liquid storage bladder 22 is drawn into the inner cavity of the sealed column 5 through the water hole 51. As the sealing ring 38 continues to descend, it acts as a piston to pressurize the sugar solution within the sealed column 5, forcing the sugar solution to be transported to the ejector 37 through the delivery hose 36, and then sprayed into the soaking tank 11 at a certain pressure through the ejector 37, causing strong disturbance of the liquid in the soaking tank 11 again, enhancing the mass transfer between the sugar solution and the raw materials, and effectively improving the mixing uniformity and penetration efficiency during the sugar production process.

[0042] All components in this device that come into contact with the sugar solution have undergone corrosion-resistant treatment to ensure chemical stability and service life under high sugar, high humidity, and long-term immersion conditions.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
