Description

Technical Field

[0001] The present invention relates to the technical field of industrial food processing, and particularly to a softening device for raisin processing. Background Art

[0002] In raisin production, the softening process is a key link, which directly affects the final quality of raisins. The main purpose of the softening process is to improve the hard lumps or uneven drying phenomena caused by uneven moisture distribution during the drying process of raisins, so that the raisins can achieve uniform dryness and softness as a whole. At the same time, the softening process also helps to remove some fruit stalks and impurities in the raisins, improving the purity and taste of the product. The Chinese patent application with the application number 202010883088.1 discloses "a raisin softening device and its softening processing method, including a softening box body, a rolling support mechanism and a softening filter cylinder. The bottom end outer wall of the softening box body is in a hemispherical structure, and a support sleeve is vertically arranged on the bottom end outer wall. A humidifier is arranged in the inner cavity of the support sleeve. The rolling support mechanism includes an annular support ring, a plurality of arc-shaped support plates and a base. The rolling support mechanism is placed in the inner cavity of the softening box body. The softening filter cylinder is a spherical hollow structure, and a feed inlet communicating with the inner cavity is opened at the top end. A sealing column is inserted into the inner cavity of the feed inlet through internal threads. The softening filter cylinder is rollingly engaged in the rolling support mechanism. The present invention is a raisin softening device that atomizes the pumped water by using a humidifier, removes calcium ions and magnesium ions, sprays it out through the nozzles of the spray heads, sprays it into the inner cavity of the humidifier through the mesh plate, and finally softens the raisins in the softening filter cylinder to achieve batch softening operations and replace manual labor";

Detailed implementation manners

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] A softening device for raisin processing in this embodiment, as Figures 1 to 6 shown, includes a conveying device 1, and also includes a feeding and discharging mechanism 2 and a mixing mechanism 3;

[0027] The feeding and discharging mechanism 2 includes a support frame 201 and a softening cylinder 205. The support frame 201 is arranged at the right end of the conveying device 1, and the softening cylinder 205 is arranged inside the support frame 201;

[0028] A control cabinet 4 is arranged at the right end of the support frame 201. A steam pipe 5 is arranged between the support frame 201 and the control cabinet 4. The top end of the steam pipe 5 is located above the softening cylinder 205, and a top cover 6 is arranged at the top end of the softening cylinder 205.

[0029] In this embodiment, as Figures 1 to 3As shown, the feeding and discharging mechanism 2 includes an arc-shaped groove 202, a rotating cylinder 203 and a connecting column 204. The arc-shaped groove 202 is formed in the front and rear side walls of the support frame 201. The rotating cylinder 203 is arranged inside the support frame 201 and is movably sleeved outside the softening cylinder 205. There are two connecting columns 204, which are respectively movably installed in the two arc-shaped grooves 202. The rotating cylinder 203 is located between the two connecting columns 204. The two connecting columns 204 are fixedly connected to the bottom end of the outer side wall of the rotating cylinder 203;

[0030] The raisins after softening treatment are transported by the conveying device 1, the raisins are loaded through the softening cylinder 205, the equipment is controlled by the control cabinet 4, the steam is guided into the softening cylinder 205 through the steam pipe 5, and the top cover 6 is used to block the top end of the softening cylinder 205 to reduce the loss of steam from the softening cylinder 205. The movement of the connecting column 204 is guided by the arc-shaped groove 202, so that when the connecting column 204 follows the translation frame 208 and moves in the direction close to the control cabinet 4, it rises in an arc along the direction of the arc-shaped groove 202 and rises in the translation frame 208. When the connecting column 204 is located at the bottom end of the arc-shaped groove 202, it is simultaneously located at the bottom end of the translation frame 208. After moving, when the connecting column 204 is located at the top end of the arc-shaped groove 202, it is simultaneously located at the top end of the translation frame 208. The movement of the connecting column 204 drives the rotating cylinder 203 to rotate with the two ends of the connecting frame 206 as the axis.

[0031] In this embodiment, as Figures 2 to 4 shown, the feeding and discharging mechanism 2 includes a connecting frame 206, a limiting cylinder 207 and a translation frame 208. The connecting frame 206 is movably sleeved in the middle of the outer side of the softening cylinder 205. The two ends of the connecting frame 206 are movably installed on the front and rear side walls of the support frame 201. There are two groups of limiting cylinders 207, which are respectively fixedly installed on the front and rear side walls of the support frame 201. There are two translation frames 208, which are respectively located on the front and rear side walls of the support frame 201 and are respectively movably sleeved on one end of the two connecting columns 204 located outside the arc-shaped groove 202;

[0032] The softening cylinder 205 is connected through the connecting frame 206, so that when the connecting column 204 moves, it rotates with the two ends of the connecting frame 206 connected to the support frame 201 as the axis, so that the softening cylinder 205 rotates synchronously with the rotating cylinder 203. The translation frame 209 is connected through the limiting cylinder 207.

[0033] In this embodiment, as Figure 2As shown, the feeding and discharging mechanism 2 includes a translation frame 209, a threaded rod 210, and a first motor 211. The translation frame 209 is movably installed on the outer side wall of the support frame 201, and the front and rear ends are respectively inserted and installed in two limiting cylinders 207. One end of the translation frame 209 close to the conveying device 1 is fixedly connected to two translation frames 208 respectively. In the middle of one end of the translation frame 209 located on the right side wall of the support frame 201, a screw sleeve is fixedly installed. One end of the threaded rod 210 close to the support frame 201 is movably installed on the right side wall of the support frame 201, and the other end is movably installed on the top of the control cabinet 4. The threaded rod 210 is movably installed in the screw sleeve on the translation frame 209 through threads. The first motor 211 is fixedly installed at the inner top of the control cabinet 4, and the output shaft of the first motor 211 is fixedly connected to the end of the threaded rod 210 far from the support frame 201;

[0034] By driving the threaded rod 210 to rotate through the first motor 211, the translation frame 209 is driven to move in the direction close to the control cabinet 4 by the rotation of the threaded rod 210. When the translation frame 209 moves, the connecting column 204 is driven to move through the translation frame 208.

[0035] On other levels, this embodiment also provides a mixing mechanism 3 for making the raisins in the softening cylinder 205 be softened more fully, as Figures 4 to 6 shown, the mixing mechanism 3, the mixing mechanism 3 includes an elastic bottom layer 301, and the elastic bottom layer 301 is arranged at the inner bottom end of the softening cylinder 205.

[0036] In this embodiment, as Figure 4 shown, the mixing mechanism 3 includes a rotating frame 302, a toothed ring 303, and a first gear 304. The rotating frame 302 is located inside the rotating cylinder 203 and is fixedly installed at the bottom end of the softening cylinder 205. The toothed ring 303 is fixedly installed at the inner bottom end of the rotating frame 302 and is movably installed at the inner bottom end of the rotating cylinder 203. The first gear 304 is movably installed at the inner bottom end of the rotating cylinder 203 and is movably connected to the inner side of the toothed ring 303 through meshing;

[0037] The bottom end of the softening cylinder 205 is closed by the elastic bottom layer 301, and due to the elastic force of the elastic bottom layer 301, after the elastic bottom layer 301 is lifted by the top ball 311, it deforms to lift the raisins piled on the elastic bottom layer 301, so that the raisins at the bottom layer in the softening cylinder 205 and the raisins at the top layer change positions, so that all the raisins in the softening cylinder 205 can be fully affected by the steam for softening treatment. By driving the toothed ring 303 to rotate through the first gear 304, the rotating frame 302 is driven to rotate synchronously with the rotating frame 302. By driving the softening cylinder 205 to rotate inside the rotating cylinder 203 through the rotating frame 302, the mixing effect of the raisins in the softening cylinder 205 is further improved, and the softening effect of the raisins is improved.

[0038] In this embodiment, as Figure 4 shown, the mixing mechanism 3 includes a second motor 305, a mixing roller 306, and a second gear 307. The second motor 305 is fixedly installed at the bottom end of the rotating cylinder 203. The output shaft of the second motor 305 passes through the bottom end of the rotating cylinder 203 and is fixedly connected to the first gear 304. The mixing roller 306 is movably installed at a position slightly below the middle inside the softening cylinder 205. There are two second gears 307 in total. One of them is fixedly installed at one end of the mixing roller 306 outside the softening cylinder 205, and the other is movably sleeved at the other end of the mixing roller 306 outside the softening cylinder 205. Both second gears 307 are movably connected to the top end of the rotating cylinder 203 through meshing;

[0039] The first gear 304 is driven by the second motor 305 to rotate, so as to drive the softening cylinder 205 to rotate. When the softening cylinder 205 rotates, it drives the mixing roller 306 to rotate synchronously. Among the two second gears 307, one fixedly connected to the mixing roller 306 drives the mixing roller 306 to rotate when following the rotation of the softening cylinder 205 because it is movably connected to the top end of the rotating cylinder 203 through meshing. The other second gear 307 movably connected to the mixing roller 306 supports the mixing roller 306. The raisins in the softening cylinder 205 are stirred by the rotating mixing roller 306, further improving the mixing effect of the raisins in the softening cylinder 205 and the uniformity during the softening process of the raisins.

[0040] In this embodiment, as Figure 5 and Figure 6 shown, the mixing mechanism 3 includes a support column 308 and a spiral frame 309. The bottom end of the support column 308 is fixedly installed at the middle of the inner bottom end of the rotating cylinder 203. A connecting plate is arranged in the middle of the rotating frame 302, and the middle of the connecting plate is movably sleeved outside the support column 308. The spiral frame 309 is fixedly installed at the top end of the support column 308. Spiral baffles are arranged at both ends of the spiral frame 309, and the two spiral baffles are arranged in a circumferential arrangement;

[0041] The spiral frame 309 is fixed by the support column 308. When the rotating frame 302 drives the softening cylinder 205 to rotate, the support column 308, the spiral frame 309, and the rotating cylinder 203 all remain stationary.

[0042] In this embodiment, as Figure 5 and Figure 6 shown, the mixing mechanism 3 includes a lifting column 310, a top ball 311, and a spring 312. There are four lifting columns 310 in total, and they are evenly and movably installed on the connecting plate inside the rotating frame 302 in a circumferential arrangement. The top ball 311 is fixedly installed at the top end of each lifting column 310. There are four springs 312 in total, and they are respectively movably sleeved on each lifting column 310 and are located between the connecting plate and the top ball 311;

[0043] The rotating frame 302 drives the lifting column 310 to rotate around the support column 308 simultaneously. When the two lifting columns 310 arranged diagonally move to the two spiral plates on the spiral frame 309, the top balls 311 at the top of the lifting columns 310 first come into contact with the spiral plates. The top balls 311 are squeezed by the spiral plates. At this time, the lifting columns 310 are driven by the top balls 311 to gradually descend, causing the springs 312 to be compressed. When the top balls 311 leave the bottom ends of the spiral plates following the rotation of the rotating frame 302, the elastic force of the springs 312 causes the top balls 311 to pop out quickly. The top balls 311 that pop out quickly push up the elastic bottom layer 301, causing the raisins piled on the elastic bottom layer 301 to be bounced upward. In cooperation with the rotation of the softening cylinder 205 and the agitation of the mixing roller 306, the raisins in the softening cylinder 205 are evenly mixed, and the raisins in the softening cylinder 205 are evenly affected by the steam, improving the softening effect of the raisins.

[0044] Working principle: When the present invention is in use, the raisins to be softened need to be first placed into the softening cylinder 205. The control cabinet 4 is used to control the start of the first motor 211. The first motor 211 drives the threaded rod 210 to rotate. The rotation of the threaded rod 210 drives the translation frame 209 to move in the direction close to the control cabinet 4. When the translation frame 209 moves, the connecting column 204 is driven by the translation frame 208, and the rotating cylinder 203 is driven by the connecting column 204. Driven by the translation frame 208, the connecting column 204 moves upward in an arc along the arc-shaped groove 202, and the rotating cylinder 203 follows the movement of the connecting column 204. When the rotating cylinder 203 moves, it drives the softening cylinder 205 to rotate with the two ends of the connecting frame 206 as the axes, causing the bottom end of the softening cylinder 205 to rotate upward and its top end to rotate downward. After the top end of the softening cylinder 205 rotates out from under the top cover 6, the raisins to be softened can be placed into the softening cylinder 205;

[0045] After the raisins are placed, the first motor 211 drives the threaded rod 210 to reverse, driving the translation frame 209 to move in the direction of the support frame 201, and driving the connecting column 204 to descend along the arc-shaped groove 202 through the translation frame 208, causing the softening cylinder 205 to rotate upward with the two ends of the connecting frame 206 as the axes. When the connecting column 204 moves to the bottom end of the arc-shaped groove 202, the top end of the softening cylinder 205 returns under the top cover 6;

[0046] Then, the control cabinet 4 is used to control the steam pipe 5 to conduct, so that the steam for softening is introduced into the softening cylinder 205. When performing the softening treatment, the control cabinet 4 is also used to control the start of the second motor 305, and the second motor 305 drives the first gear 304 to rotate. When the first gear 304 rotates, the rotating frame 302 is driven to rotate through the toothed ring 303, so that the softening cylinder 205 rotates in the rotating cylinder 203 following the rotating frame 302. When the softening cylinder 205 rotates, it drives the mixing roller 306 to rotate synchronously, and makes the second gear 307 follow the mixing roller 306 to rotate along the top of the rotating cylinder 203. And one of the second gears 307 fixedly connected to the mixing roller 306 is movably connected to the top of the rotating cylinder 203 through meshing. Therefore, when the softening cylinder 205 rotates, the mixing roller 306 is driven to rotate through this second gear 307, and the other second gear 307 movably connected to the mixing roller 306 is used to support the mixing roller 306. The rotating mixing roller 306 agitates the raisins undergoing softening treatment in the softening cylinder 205, so that the raisins in the softening cylinder 205 are agitated and dispersed, preventing the raisins from sticking together under the action of steam during the softening treatment;

[0047] When the softening cylinder 205 rotates, the rotating cylinder 203 and the support column 308 remain stationary. When the rotating frame 302 rotates, it drives the lifting column 310 to rotate around the support column 308 at the same time. When the two lifting columns 310 arranged diagonally move to the two spiral plates on the spiral frame 309, the top balls 311 at the top of the lifting columns 310 first come into contact with the spiral plates. The top balls 311 are squeezed by the spiral plates. At this time, the lifting columns 310 are driven to gradually descend through the top balls 311, so that the spring 312 is compressed. When the top balls 311 leave the bottom end of the spiral plate following the rotation of the rotating frame 302, the elastic force of the spring 312 causes the top balls 311 to pop out quickly. The top balls 311 that pop out quickly push up the elastic bottom layer 301, causing the raisins piled on the elastic bottom layer 301 to be bounced upward. Cooperating with the rotation of the softening cylinder 205 and the agitation of the mixing roller 306, the raisins in the softening cylinder 205 are evenly mixed, so that the raisins in the softening cylinder 205 are evenly affected by the steam, improving the softening effect of the raisins;

[0048] After the softening process ends, stop the steam extraction from the steam pipe 5 again through the control cabinet 4, and start the first motor 211 to drive the rotation of the softening cylinder 205, so that the top of the softening cylinder 205 rotates downward. After the rotation ends, the opening of the softening cylinder 205 faces the conveying device 1, so that the softened raisins in the softening cylinder 205 are poured onto the conveying device 1, and the raisins are transported through the conveying device 1. During the pouring process, the second motor 305 is still started, so that the softening cylinder 205 and the mixing roller 306 continue to rotate, and the top ball 311 continuously presses against the elastic bottom layer 301, so that the raisins in the softening cylinder 205 are evenly poured out. And by continuously making the elastic bottom layer 301 perform elastic movement, the droplets accumulated at the bottom end inside the softening cylinder 205 due to steam during the softening process of the raisins are also discharged from the softening cylinder 205, so as to facilitate the subsequent continuous softening process of the raisins.
