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

[0026] The raw materials for processing fruit and vegetable chips are mainly fruits and vegetables. The processed fruit and vegetable chips are crispy but not greasy. They not only retain the color, aroma and taste of the original fruits and vegetables, but also have the characteristics of low calories, low fat, high fiber, rich in vitamins and minerals.

[0027] Please refer to Figure 1 - Figure 4, since the traditional transportation of fruit and vegetable chips is usually carried out using a conveyor belt, and in order to cool the fruit and vegetable chips, the transportation speed is usually slowed down to facilitate the natural cooling of the fruit and vegetable chips. To accelerate the natural cooling time of the fruit and vegetable chips without affecting the transportation speed of the fruit and vegetable chips, and at the same time filter out the residual debris in the fruit and vegetable chips, a fruit and vegetable chip transportation and screening device is provided, which consists of a transportation frame 1, a blanking hopper 2 installed at the bottom of the transportation frame 1, and a transportation mechanism 3 arranged on the transportation frame 1. The cross-section of the blanking hopper 2 is set as an inverted trapezoid, making it more convenient for the fruit and vegetable chip debris to be discharged. The transportation mechanism 3 is used to transport the fruit and vegetable chips and screen out the debris. At the bottom of the blanking hopper 2, a discharge box 5 for discharging the fruit and vegetable chip debris is fixedly installed, and the bottom of the discharge box 5 is set to be inclined and has an opening, so that the screened fruit and vegetable chip debris can be discharged for centralized treatment. On one side of the top of the transportation frame 1 is the feeding port, and the defatted fruit and vegetable chips are poured onto the annular sieve plate 31 through the feeding port.

[0028] To ensure that the transportation efficiency of the fruit and vegetable chips is not affected while accelerating their natural cooling speed, this is achieved through the transportation mechanism 3, which includes an annular sieve plate 31 rotatably arranged at the bottom of the transportation frame 1, and the annular sieve plate 31 is located above the blanking hopper 2. The blanking hopper 2 can provide a supporting effect for the annular sieve plate 31, making the rotation of the annular sieve plate 31 more stable. There is also a blanking port 32 arranged on one side of the transportation frame 1, and a baffle plate 33 detachably arranged with the transportation frame 1 is provided on one side of the blanking port 32. The annular sieve plate 31 drives the fruit and vegetable chips to rotate to the blanking port 32, and the baffle plate 33 acts on the fruit and vegetable chips. An internal gear ring 34 is fixedly installed inside the annular sieve plate 31. The transportation mechanism 3 further includes a driving component 35 arranged on the transportation frame 1 for driving the annular sieve plate 31 to rotate to transport the fruit and vegetable chips. Among them, a blowing component 36 for reducing the temperature of the fruit and vegetable chips is also arranged on the top of the transportation frame 1.

[0029] As Figure 3 shown, to drive the rotation of the internal gear ring 34 and at the same time drive the blowing component 36 to start operating, so as to blow and cool the fruit and vegetable chips while transporting them, this is achieved by setting the driving component 35. Specifically, the driving component 35 includes a support frame 351 fixedly installed inside the transportation frame 1, and three transmission gears 352 circumferentially and equidistantly distributed and meshed inside the internal gear ring 34. A transmission vertical shaft 353 is fixedly installed at the axles of the three transmission gears 352, and the transmission vertical shaft 353 passes through the support frame 351 and is rotatably connected to it through a bearing. A servo motor 354 is detachably installed on the top of the support frame 351. A gear one 355 is fixed to the output shaft of the servo motor 354, and a gear two fixed to any one of the transmission vertical shafts 353 is meshed on one side of the gear one 355.

[0030] As Figure 3As shown in the figure, while the fruit and vegetable chips are being transported, they are blown and cooled by air. At the same time, the debris in the fruit and vegetable chips can be blown into the blanking hopper 2 through the annular sieve plate 31, which speeds up the cooling rate of the fruit and vegetable chips. Specifically, it includes three fan blades 361 arranged on the top of the conveying frame 1, and drive shafts 362 respectively fixed to the three fan blades 361. The three drive shafts 362 are respectively matched with the three transmission vertical shafts 353. A transmission belt 363 is arranged for transmission between the tops of the drive shaft 362 and the transmission vertical shaft 353. The two ends of the transmission belt 363 are respectively connected to the drive shaft 362 and the transmission vertical shaft 353 through pulleys for transmission connection. And a support rod 364 fixed to the conveying frame 1 is rotatably connected to the drive shaft 362 through a bearing. An air inlet net matching the three fan blades 361 is detachably embedded on the top of the conveying frame 1. When the fan blades 361 rotate, an air flow is formed, and the air flow blows onto the fruit and vegetable chips through the air inlet net.

[0031] As Figure 2 As shown in the figure, the debris of the fruit and vegetable chips falls onto the blanking hopper 2 through the annular sieve plate 31. In order to prevent the debris of the fruit and vegetable chips from adhering to the blanking hopper 2, a scraping component 4 for scraping off the residual debris of the fruit and vegetable chips is arranged on the blanking hopper 2. The scraping component 4 includes four scraping rods 41 arranged in a circumferential array and sliding on the inner wall of the blanking hopper 2. A connecting vertical rod 42 detachably connected to the internal gear ring 34 is fixed on the scraping rod 41.

[0032] When transporting the fruit and vegetable chips, the fruit and vegetable chips are added through the feeding port on one side of the annular sieve plate 31. Then, the servo motor 354 is started. The output shaft of the servo motor 354 drives the gear one 355 at one end to rotate. The gear one 355 drives the meshing gear two to rotate. The gear two drives the transmission vertical shaft 353 at its axis to rotate. The transmission vertical shaft 353 drives the transmission gear 352 at its bottom to rotate. The transmission gear 352 drives the internal gear ring 34 on one side to rotate. The internal gear ring 34 drives the annular sieve plate 31 on its outside to rotate, and the annular sieve plate 31 drives the fruit and vegetable chips on it to move.

[0033] At the same time, the internal gear ring 34 drives the remaining transmission gears 352 to rotate. The transmission gears 352 drive the transmission vertical shafts 353 on them to rotate, so that the three transmission vertical shafts 353 rotate simultaneously. The three transmission vertical shafts 353 respectively drive the three drive shafts 362 to rotate through the transmission belts 363 at their tops. The drive shafts 362 drive the fan blades 361 at their bottoms to rotate, blowing and cooling the fruit and vegetable chips during transportation. At the same time, the internal gear ring 34 drives the connecting vertical rod 42 to rotate. The connecting vertical rod 42 drives the scraping rod 41 at its bottom to rotate on the inner wall of the blanking hopper 2. The scraping rod 41 scrapes off the debris of the fruit and vegetable chips adhering to the inner wall of the blanking hopper 2 into the discharge box 5, and then discharges it to the external collection box for collection, and finally centrally processed.

[0034] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. Moreover, since the present utility model is mainly used to protect mechanical devices, the control mode will not be explained in detail herein.

[0035] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
