Description

Technical Field

[0001] The invention relates to the field of food production, in particular to a negative pressure filling device for food slurry. Background Art

[0002] Negative pressure filling equipment is a device commonly used in food production. Its purpose is to introduce food slurry into a specific processing environment to make better and higher quality food; Among them, when making chocolate, the production of hollow chocolate needs to be filled with negative pressure, but during operation, the chocolate will be cooled in the middle of the preparation device. When the chocolate is fed into the mold slot of the device, the chocolate not only needs to be evenly heated, but also needs to be evenly spread to avoid unnecessary bubbles, which will cause problems with the quality of the chocolate. In addition, hollow chocolate is difficult to shape, which can easily make the internal thickness of the chocolate uneven. Too thin chocolate will cause stress damage to the chocolate, which will make it difficult to cool afterwards and have a poor taste. At the same time, when the chocolate is molded, the existing method is to divide the chocolate into two hemispheres and make them in sequence. After the preparation is completed, the two parts are spliced, but the joint after splicing needs to be scraped off with a spatula to remove excess chocolate; In addition, the thin parts inside the chocolate will make the taste harder, affecting the gloss of the product, and it will be easier to melt during transportation, affecting the next preparation (such as making chocolate with liqueur filling). The thick parts will not only taste soft, but also be too sweet. At the same time, it will also cause this part of the chocolate to form too slowly, resulting in a slower cooling speed, which will cause stress in the chocolate and make the structure unstable. It will also be more likely to produce bubbles, causing the product quality to decline again. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1 to Figure 9 , including an operating chamber 100, a stabilizing platform 200 is arranged on the surface of the operating chamber 100, and the stabilizing platform 200 is fixedly connected to the operating chamber 100. When the device is working, it can play a certain stabilizing role in the vibration generated by the device, and a swing mechanism 300. The swing mechanism 300 includes a first driving motor 301 arranged inside the operating chamber 100, and the output end of the first driving motor 301 is fixedly connected to a first connecting rod 302, and the first connecting rod 302 is provided with a first connecting block 303 inside. The coordination component is centered on the axis of the operating chamber 100, vertically It is directly arranged inside the operating chamber 100, and is used for assisting in shaping the chocolate slurry in the working state. The manufacturing mechanism 400 includes a semi-arc cover plate 401 arranged on the surface of the coordination component. The interior of the semi-arc cover plate 401 is centered on the axis of the semi-arc cover plate 401 and is provided with a plurality of groups of second semi-circular openings 402. A negative pressure device 409 is provided on the side of the surface of the semi-arc cover plate 401 away from the second semi-circular openings 402. The preparation component is arranged on the surface of the semi-arc cover plate 401 and corresponds to the number of the second semi-circular openings 402. In the working state, it is used to cooperate with the coordination component to shape the chocolate.

[0027] The coordination component includes a rotating block 311 vertically arranged inside the operating chamber 100, the surface of the rotating block 311 is rotatably connected to the second connecting block 312, the surface of the second connecting block 312 is provided with a second connecting rod 313, the second connecting rod 313 is provided with a base 314 at one end away from the second connecting block 312, and the inside of the base 314 is provided with a condensing piece 315.

[0028] During use, the first driving motor 301 drives the first connecting rod 302 and the first connecting block 303 to work, and the base 314 is always in a tilted state as a whole. The base 314 connected to the first connecting block 303 is the highest point. Because when the slurry is sent into the closed chamber formed by the second semicircular mouth 402 and the semicircular mold 3153 through the negative pressure device 409, the higher inclined surface is the negative pressure output end. When the slurry enters the closed chamber, it is also necessary to tilt and shake the slurry to prevent the negative pressure from introducing the slurry into the negative pressure pipe 406 and the second annular pipe 407, causing damage to the device. After the slurry is sent into each inlet tube 404 through the first annular tube 405, when the first disk 4121 is not working, that is, the two sets of matching holes do not rotate to the circulation holes, the slurry cannot be transmitted through negative pressure. When the receiving part 412 is working, that is, the two sets of matching holes are aligned to the two sets of circulation holes, the negative pressure generated by the negative pressure device 409 will be transported to the inside of the negative pressure tube 406 through the second annular tube 407, so that negative pressure is generated in its closed chamber, and the slurry is sent into the interior.

[0029] It should be noted that the interior of the base 314 is a hollow structure, which can hold tap water, purified water and other similar temperature-controlled liquids, so as to avoid the problem of chocolate cooling too quickly or too slowly due to uneven heating during the chocolate molding process, thereby improving the preparation quality of the chocolate.

[0030] Reference Figure 2~Figure 9 The solidifying member 315 includes a truncated cone 3151 arranged inside the base 314, and the truncated cone 3151 is provided with first semicircular openings 3152 corresponding to the number of the second semicircular openings 402, and each first semicircular opening 3152 is provided with a semicircular mold 3153 inside. When the semicircular mold 3153 and the second semicircular opening 402 are fitted together, they are spherical in shape, which is a fixed shape for making chocolate pieces.

[0031] A positive pressure device 403 is arranged on the surface of the semi-arc cover plate 401, and several groups of inlet tubes 404 are arranged on the surface of the semi-arc cover plate 401 close to the preparation component. A first annular tube 405 is arranged at the end of the inlet tube 404, and a transfer hole is opened inside the first annular tube 405. Negative pressure tubes 406 corresponding to the number of the inlet tubes 404 are arranged on the surface of the semi-arc cover plate 401, and a second annular tube 407 is arranged at the end of the negative pressure tube 406. Annular teeth 408 are arranged on the side of the surface of the semi-arc cover plate 401 away from the negative pressure device 409.

[0032] During use, the slurry is connected to the transfer hole of the first annular tube 405 through an external pipe, so that the slurry can be sent into the interior of the first annular tube 405 through the external pipe, and then enter the interior of the cavity created by the semicircular mold 3153 and the second semicircular opening 402 through the introduction pipe 404. The number of each introduction pipe 404 corresponds to the number of cavities created by the semicircular mold 3153 and the second semicircular opening 402.

[0033] The other end of each inlet tube 404 passes through the semi-arc cover plate 401 to the inside of the preparation component, and the inside of the second annular tube 407 is fixedly connected to the output end of the negative pressure device 409.

[0034] Reference Figure 3~Figure 9 The preparation component includes a loading cylinder 411 arranged on the surface of the semi-arc cover plate 401, and two groups of guide holes are opened inside the loading cylinder 411, and the two groups of guide holes are respectively connected to the introduction pipe 404 and the negative pressure pipe 406, and a receiving part 412 is rotatably connected inside the loading cylinder 411, and a directional cylinder 413 is coaxially arranged inside the loading cylinder 411 with the receiving part 412, and a short rod 414 is rotatably connected inside the directional cylinder 413, and pinions 415 are arranged at both ends of the short rod 414, and a rotating shaft 416 is coaxially arranged inside the loading cylinder 411 with the directional cylinder 413, and a second circular tooth 417 is fixedly connected to the surface of the rotating shaft 416, and oil discharge holes are opened inside the rotating shaft 416, and an air bag 418 is arranged near the end of the rotating shaft 416 near the pinion 415, and circulation holes corresponding to the number of the guide holes are opened at the end of the loading cylinder 411 near the air bag 418.

[0035] The receiving member 412 includes a first disk body 4121 rotatably connected to the inside of the loading cylinder 411. The surface of the first disk body 4121 is provided with first circular teeth 4122. The surface of the first disk body 4121 is provided with two sets of matching holes. The first circular teeth 4122 are of a special shape. When the first circular teeth 4122 are working, they rotate in coordination with one of the pinions 415.

[0036] When the two sets of matching holes on the surface of the first disk 4121, the guide holes and the circulation holes of the loading cylinder 411 are on the same vertical line, and the expansion of the airbag 418 seals the conical section of the loading cylinder 411, the semicircular mold 3153 and the second semicircular mouth 402 chamber will introduce the slurry through negative pressure.

[0037] One of the pinions 415 is meshed with the receiving member 412 , the other pinion 415 is meshed with the second circular tooth 417 , the end of the rotating shaft 416 is meshed with the annular tooth 408 , and the end of each airbag 418 is fixedly connected to the output end of the positive pressure device 403 .

[0038] During use, when the airbag 418 is not inflated, it will shrink inside the loading cylinder 411; when the airbag 418 is inflated, it will expand out from the inside of the tapered end of the loading cylinder 411. The shape of the airbag 418 is composed of a sphere and a cylinder, and the tapered section of the airbag 418 close to the loading cylinder 411 is spherical, ensuring that the airbag 418 can be less contaminated with chocolate slurry when it is recovered from the tapered end. Before the airbag 418 is inflated, an oil discharge hole is opened inside the rotating shaft 416, and anti-adhesion oil, butter, edible oil, olive oil and other grease with lubricating function can be filled into the semicircular mold 3153 and the second semicircular opening 402 chamber, as well as the surface of the airbag 418 through the oil discharge hole. When the slurry temperature is too high, it is necessary to turn on the first drive motor 301 in advance to allow the oil to cover the inside of the chamber. Then, when the airbag 418 expands, the cylindrical part of the airbag 418 will seal the conical part of the loading cylinder 411, so that the oil no longer enters the inside of the chamber.

[0039] It should be noted that if a large diameter hollow chocolate is prepared and the output of the negative pressure device 409 is sufficient, when the air bag 418 is expanded by the negative pressure in the semicircular mold 3153 and the second semicircular opening 402 chamber, the positive pressure device 403 can be removed to reduce the purchase cost. Specific implementation method; Preparation of hollow chocolate: Connect the slurry pipeline to the first annular tube 405, then introduce oil into the semicircular mold 3153 of the coagulation member 315 and the second semicircular opening 402 on the semi-arc cover plate 401 through the oil lowering hole, and at the same time, the oil covers the surface of the airbag 418, and then rotate the annular gear 408. When the annular gear 408 rotates, it drives the rotating shaft 416 to rotate. At the same time, the positive pressure device 403 sends gas into the airbag 418 to expand it to the inside of the spherical chamber formed by the second semicircular opening 402 and the semicircular mold 3153. When the rotating shaft 416 rotates, the rotating shaft 416 drives the second semicircular opening 402 and the semicircular mold 3153 to rotate. The second circular teeth 417 work, the small gear 415 engaged with the second circular teeth 417 drives the short rod 414 to rotate, and at this time the receiving part 412 engaged with the other small gear 415 starts to rotate. When the first disk 4121 rotates to a certain angle, the negative pressure generated by the negative pressure device 409 will send the slurry into the spherical chamber through the introduction pipe 404. Then the slurry enters, the first driving motor 301 starts to work, and the first connecting rod 302 drives the first connecting block 303 to operate the base 314 to move. The base 314 is tilted and away from the second connecting rod 313. The side is at the lowest height. At this time, the ball The slurry inside the spherical cavity begins to slowly cover the inside of the spherical cavity, and then the annular gear 408 is rotated again to close the spherical cavity. When the base 314 is operated at an inclined angle, it will be restricted by the second connecting block 312 and the second connecting rod 313. At the same time, the air bag 418 expands again, further reducing the space inside the spherical cavity, and further correcting the outer and inner surfaces of the hollow chocolate to discharge the bubbles inside the chocolate slurry and expand and flatten the weaker parts of the chocolate surface. The chocolate slurry expands with the expansion of the air bag 418 to make the unformed chocolate The thickness of the force-cut surface is uniform. The thicker slurry has not yet solidified, and the airbag 418 drives it to the weak area similar to a rolling pin. Then wait for the chocolate to cool down. After the chocolate slurry is cooled, the positive pressure device 403 stops outputting. At this time, the gas inside the airbag 418 will be discharged, and the airbag 418 will retract to the inside of the conical section of the loading cylinder 411. Then, the semi-arc cover 401 is opened to take out the hollow chocolate. The retracted part of the airbag 418, that is, the conical section of the loading cylinder 411, will have holes for preparing the chocolate filled with wine, which is used to send it to the next preparation process of filling wine or other materials.

[0041] Preparation of infiltrated chocolate: When personnel need to infiltrate chocolate slurry into dry solid food, they need to open the semi-arc cover 401. At this time, there is no need to operate the positive pressure device 403. After placing the food that needs negative pressure infiltration inside the semicircular mold 3153, cover the semi-arc cover 401, open the negative pressure device 409, and start intermittent operation of the negative pressure device 409, so that the slurry intermittently enters the spherical chamber, and the chocolate slurry is infiltrated into the pores of the food by negative pressure. When necessary, the first drive motor 301 can be turned on to drive the base 314 to move for better negative pressure infiltration.

[0042] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
