Description

Technical Field

[0001] This invention relates to the field of braised duck processing technology, specifically to a braising device for braised duck with a positioning and anti-loosening structure. Background Technology

[0002] Braised duck is a very popular traditional delicacy with a rich spicy flavor and unique taste. Its production process is relatively complex, involving several steps such as marinating, blanching, seasoning, and roasting. The marinating device for braised duck is a special piece of equipment used in the marinating process of making braised duck. Marinating is a very important step in the production of braised duck. The marinating device is used to evenly coat the duck with sauce.

[0003] Current situation: 1. When using the existing ordinary marinating equipment for braised duck, hooks are usually used to hang the duck on the moving mechanism of the equipment. When the duck is moved, the duck may shake or loosen, which will cause the sprayed marinade to not be evenly sprayed on the duck, affecting the marinating effect. 2. When using existing ordinary marinating equipment for braised duck, the marinade is usually sprayed out through nozzles on both sides of the duck body. However, this spraying process can lead to the marinade not being evenly applied to the duck body, which affects the final marinating effect. 3. When using existing ordinary marinating equipment for braised duck, because the duck's body is irregular in shape, excess marinade will adhere to the duck's body, resulting in uneven distribution of marinade on the duck's body and affecting the final marinating effect.

When the first fluid pump 103 is started, the pickling material in the material collection hopper 101 can be extracted and sent into the storage tank 106.

[0029] In this embodiment, as Figure 2As shown, one end of the first connecting pipe 104 is connected to the top of the storage box 106, and one end of the second connecting pipe 109 is connected to the arc-shaped pipe 107. The inner wall of the arc-shaped pipe 107 is provided with several evenly distributed nozzles. The bottom of the storage box 106 is provided with a motor, and the output end of the motor is provided with stirring blades. When the motor is started, it drives the stirring blades to stir the marinade in the storage box 106. When the second fluid pump 108 is started, it can draw the marinade in the storage box 106. Then the marinade enters the arc-shaped pipe 107 through the second connecting pipe 109, and then is sprayed out through several nozzles on the arc-shaped pipe 107, so that the marinade can be evenly sprayed on the duck.

[0030] In this embodiment, as Figure 2 and Figure 3 As shown, the track assembly 2 includes a cover plate 201 installed on the top of the arc-shaped baffle 105. A toothed ring 202 and an annular track 203 are installed at the bottom of the cover plate 201. A T-shaped track groove is provided on the inner wall of the annular track 203, and a T-shaped slider 402 is slidably installed in the T-shaped track groove. The T-shaped slider 402 can slide in the T-shaped track groove, so that the moving assembly 4 and the positioning anti-loosening assembly 5 can make annular motion along the annular track 203.

[0031] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, the first bevel gear 405 is meshed with the second bevel gear 408, and the spur gear 404 is meshed with the gear ring 202. When the reduction motor 407 is started, the second bevel gear 408 can drive the first bevel gear 405, the transmission rod 403, the spur gear 404 and the worm gear 406 to rotate. When the spur gear 404 rotates, it rolls on the gear ring 202, which can drive the moving component 4 and the positioning anti-loosening component 5 to make circular motion along the circular track 203, so that the marinade can be continuously sprayed onto the duck.

[0032] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, a circular hole is provided in the center of the bottom of the box 401, and the mounting tube 4021 is slidably installed in the circular hole at the bottom of the box 401. The lower part of the outer wall of the transmission rod 403 is provided with two symmetrically distributed sliding strips, and the inner wall of the mounting tube 4021 is provided with two symmetrically distributed sliding grooves. The sliding strips on the outer wall of the transmission rod 403 are slidably installed in the sliding grooves on the inner wall of the mounting tube 4021. When the transmission rod 403 is driven to rotate, the transmission rod 403 can drive the mounting tube 4021 to rotate through the sliding strips. When the mounting tube 4021 rotates, it can drive the positioning and anti-loosening component 5 to rotate, thereby driving the duck body to rotate, so that the marinade can be evenly sprayed on the duck body.

[0033] In this embodiment, as Figure 4 , Figure 5 and Figure 6 As shown, the second connecting rod 4014 is installed at the front end of the fixed tube 4016, and the worm gear 406 is meshed with the worm wheel 4011. When the worm gear 406 is driven to rotate, it can drive the worm wheel 4011 and the first connecting rod 4012 to rotate. The first connecting rod 4012 drives the fixed tube 4016 to swing in a fan shape through the push-pull rod 4013 and the second connecting rod 4014. When the fixed tube 4016 swings in a fan shape, it drives the mounting tube 4021 to move up and down through the sliding tube 4017, the third connecting rod 4018, the second mounting block 4019 and the mounting ring 4020. The sliding tube 4017 slides inside the fixed tube 4016. When the mounting tube 4021 moves up and down, it can drive the positioning anti-loosening component 5 to move up and down, so that the marinade can be evenly sprayed on the duck. When the duck moves out of the spraying area of ​​the arc tube 107, the excess marinade on the duck can be shaken off, improving the marinating effect.

[0034] In this embodiment, as Figure 5 , Figure 6 and Figure 7 As shown, the positioning and anti-loosening component 5 includes a first mounting plate 501 installed at the bottom of the mounting tube 4021. A slide rod 502 is installed at the rear end of the first mounting plate 501. A second mounting plate 503 is slidably installed on the outer wall of the slide rod 502. An electric push rod 504 is installed through the front end of the first mounting plate 501. Several L-shaped rods 505 are installed at the bottom of the first mounting plate 501. Several clamping rods 506 are installed at the bottom of the second mounting plate 503. One end of the electric push rod 504 is connected to the front end of the second mounting plate 503. When the electric push rod 504 is started, it can drive the second mounting plate 503 and several clamping rods 506 to move back and forth. The several clamping rods 506, together with the several L-shaped rods 505, can clamp and fix the duck body to prevent the duck body from loosening and shifting, which would prevent the marinade from being sprayed evenly on the duck body.

[0035] In this embodiment, as Figure 7 As shown, several L-shaped rods 505 are evenly and equidistantly distributed at the bottom of the first mounting plate 501, and several clamping rods 506 are evenly and equidistantly distributed at the bottom of the second mounting plate 503, with the L-shaped rods 505 and the clamping rods 506 interleaved. When the duck is clamped and fixed by the clamping rods 506 and the L-shaped rods 505, the stability of the duck can be improved, so that the duck will not shift during marinating.

[0036] In this embodiment, as Figure 1 and Figure 3As shown, the moving component 4 and the positioning and anti-loosening component 5 are set as a group, and there are several groups in total. The several groups of moving components 4 and positioning and anti-loosening components 5 are distributed in a ring with the vertical center line of the ring track 203 as the origin. When the reduction motor 407 of the moving component 4 starts at the same time, it can drive the several groups of moving components 4 and positioning and anti-loosening components 5 to move in a ring along the ring track 203, and can spray marinade on multiple ducks at the same time.

[0037] The method of using this invention: The marinating device for braised duck with a positioning and anti-loosening structure operates as follows: like Figures 1 to 7 As shown, firstly, the duck is placed on several L-shaped rods 505. Then, the electric push rod 504 is activated, driving the second mounting plate 503 and several clamping rods 506 to move forward. The clamping rods 506 cooperate with the L-shaped rods 505 to clamp the duck. Next, the reduction motor 407 is activated. The reduction motor 407 drives the first bevel gear 405, transmission rod 403, spur gear 404 and worm gear 406 to rotate through the second bevel gear 408. The spur gear 404 rolls on the gear ring 202, driving the transmission rod 505 to rotate. The moving component 4 and the positioning and anti-loosening component 5 move in a ring along the annular track 203. At the same time, the transmission rod 403 drives the mounting tube 4021, the positioning and anti-loosening component 5 and the duck body to rotate through the slide bar. The worm gear 406 drives the mounting tube through the worm wheel 4011, the first connecting rod 4012, the push-pull rod 4013, the second connecting rod 4014, the first mounting block 4015, the fixed tube 4016, the sliding tube 4017, the third connecting rod 4018, the second mounting block 4019 and the mounting ring 4020. 4021. The positioning and anti-loosening component 5 and the duck body reciprocate up and down, while the first fluid pump 103 and the second fluid pump 108 are activated. The second fluid pump 108 draws the marinade from the storage tank 106, and then the marinade enters the arc-shaped pipe 107 through the second connecting pipe 109 and is sprayed out through several nozzles on the arc-shaped pipe 107. The marinade is evenly sprayed on the duck body. When the moving component 4, the positioning and anti-loosening component 5, and the duck body move out of the spraying area of ​​the arc-shaped pipe 107, the duck body moves up and down, causing... Excess marinade is shaken off and collected in the collection hopper 101. The first fluid pump 103 draws out the marinade from the collection hopper 101 and sends it into the storage box 106. When it is time to remove the duck carcass, the duck carcass moves to the notch of the arc-shaped baffle 105. The corresponding moving component 4's reduction motor 407 stops, and the electric push rod 504 is started, which drives several clamping rods 506 and several L-shaped rods 505 to move away from each other. Then, the marinated duck carcass is removed and a new duck carcass is placed on top.
