Description

Technical Field

[0001] The invention relates to the technical field of flour processing, and more specifically, to a high-fiber flour processing device and a preparation method thereof. Background Art

[0002] High-fiber flour is a special type of flour that has increased dietary fiber content on the basis of traditional flour. This type of flour is usually made from high-quality wheat and uses a special process to retain the original nutrients of wheat while adding additional dietary fiber to achieve nutritional balance. The wheat bran in high-fiber flour is rich in dietary fiber, but it also contains phytic acid, which is harmful to the human body. In order to reduce the inhibition of phytic acid on the absorption of nutrients by the human body, the wheat bran needs to be dephyticated.

[0003] At present, in the traditional production process of high-fiber flour, it is necessary to mix the pretreated wheat flour and dietary fiber, and dry them after sufficient mixing to finally obtain qualified high-fiber flour. The mixing method used in the traditional production method is generally to directly rotate the flour and stir it. Although this method can achieve sufficient mixing of wheat flour and dietary fiber, due to the fine flour particles and strong adsorption capacity, the traditional mixing method often takes more time, which leads to a relatively slow production speed of high-fiber flour.

[0048] Embodiment 2

[0049] Please refer to Figure 1 to Figure 2A processing device is used in the method for making high-fiber flour in Example 1. The processing device includes: a mixing drum 1, a support frame 2, a mixing part 3 and a discharging part 4. The mixing part 3 is connected to the mixing drum 1 and is used to mix the flour and high-fiber material in the mixing drum 1; the discharging part 4 is connected to the bottom of the mixing drum 1, and the support frame 2 is connected to the discharging part 4; wherein the discharging part 4 includes a discharging hopper 41 and a discharging mechanism 42, and the discharging mechanism 42 is arranged at the bottom of the mixing drum 1, and is used to adjust the opening of the bottom of the mixing drum 1. The opening and closing state of the mouth, when the discharge mechanism 42 is in the closed state, the bottom opening of the mixing drum 1 is in a flat state, and the flour and high-fiber material at the bottom of the mixing drum 1 can always be in contact with the mixing part 3; the discharge hopper 41 is located at the bottom of the discharge mechanism 42, and its outer side is fixed to the support frame 2, and the discharge hopper 41 is used to discharge the mixed high-fiber flour; after the mixing is completed, by adjusting the discharge mechanism 42 to the open state, the high-fiber flour in the mixing drum 1 falls vertically downward into the discharge hopper 41, and then is discharged from the discharge hopper 41.

[0050] For details, please refer to Figures 3 to 6The discharging mechanism 42 includes an opening and closing component 421 and a driving component 422. When the opening and closing component 421 is closed, the bottom opening of the mixing drum 1 is completely blocked. The state switching mode of the opening and closing component 421 is horizontal contraction and convergence. The driving component 422 is connected to the opening and closing component 421, and is used to drive the opening and closing component 421 to open and close. The opening and closing assembly 421 includes a supporting ring body 4211, a driving ring body 4212, five blocking plates 4213 and five connecting rotating rods 4214. The supporting ring body 4211 is fixedly sleeved on the lower end of the mixing drum 1, the driving ring body 4212 is located at the bottom of the supporting ring body 4211, and five limiting grooves 4215 are provided on the top of the supporting ring body 4211. Five connecting shaft bodies 4216 corresponding to the limiting grooves 4215 are fixedly installed on the top of the driving ring body 4212. The five connecting shaft bodies 4216 are slidably connected with the five limiting grooves 4215 in a one-to-one correspondence. The connecting shaft bodies 4216 slide in cooperation with the limiting grooves 4215. , so that the driving ring body 4212 can rotate at the bottom of the supporting ring body 4211, and the five sealing plates 4213 are spliced ​​to form a sealing structure with a diameter larger than the diameter of the bottom opening of the feed barrel, which can effectively seal the bottom opening of the feed barrel; one end of the five sealing plates 4213 is rotatably connected to the bottom of the mixing drum 1, one end of the five connecting rotating rods 4214 is hinged to the five sealing plates 4213 accordingly, and the other ends of the five connecting rotating rods 4214 are hinged to the driving ring body 4212, and the driving assembly 422 is connected to the driving ring body 4212, which is used to drive the driving ring body 4212 to rotate horizontally at the bottom of the supporting ring body 4211. The driving assembly 422 includes a driving motor 4221, a transmission gear 4222 and a transmission rack 4223. The fixed end of the driving motor 4221 is fixed to the supporting ring body 4211, and the transmission gear 4222 is fixed to the driving end of the driving motor 4221. The driving motor 4221 can be a servo motor, which is controlled and operated by an external controller. The matching rack 4234 is an arc-shaped rack. The transmission rack 4223 is fixedly installed on the outer ring surface of the driving ring body 4212, and the transmission gear 4222 is meshed with the transmission rack 4223.

[0051] It should be noted that the use process of the above-mentioned discharge part 4 is as follows: during normal stirring, the blocking plate 4213 is in a closed state to block the opening at the bottom of the mixing drum 1. Since the top surface of the blocking plate 4213 is horizontally arranged, the bottom of the mixing drum 1 after blocking is a horizontal plane, so that the mixed material at the bottom can be fully stirred when the stirring part 3 is stirring; and after the mixing and stirring is completed, the stirred high-fiber panel needs to be discharged from the processing equipment. At this time, by driving the motor 4221 to rotate, the transmission gear 4222 can drive the transmission rack 4223 to rotate together, and the driving ring body 4212 follows the transmission rack 4 223 rotates together, and the connecting shaft 4216 follows the driving ring body 4212 to slide along the limiting groove 4215. By driving the ring body 4212 to rotate, the connecting rotating rod 4214 can drive the sealing plate 4213 to rotate away from the bottom opening of the feed barrel until the transmission gear 4222 rotates to the end of the transmission rack 4223, and the driving motor 4221 stops rotating, so that the five sealing plates 4213 are completely separated, and the bottom opening of the feed barrel is no longer blocked by the sealing plates 4213, and the mixed high-fiber flour falls from the bottom of the feed barrel to the discharge hopper 41 below under the action of gravity, and is then discharged from the discharge hopper 41.

[0052] The processing device provided by the present invention can discharge high-fiber flour in a vertical falling manner by providing a discharge hopper 41 at the bottom of the mixing drum 1 and providing a discharge mechanism 42 between the discharge hoppers 41 and 41. Compared with the traditional mixing processing device that uses the method of discharging at the side of the mixing drum 1, there is no need for manual auxiliary discharge, nor is there any need to lift the mixing drum 1 for discharge, which speeds up the discharge speed and improves the problem of high-fiber flour discharge adhesion. In addition, when the discharge mechanism 42 is closed, the bottom of the mixing drum 1 is a horizontal plane, maintaining the structural form of the existing mixing drum 1, and avoiding affecting the mixing effect of the high-fiber flour. The opening and closing component 421 provided by the present invention is different from the traditional opening and closing structure, and its movable stroke is smaller, and it will not take up too much installation space, and it can be well adapted to the structural form of the feed drum.

[0053] Please refer to Figure 7 The stirring part 3 includes a stirring motor 31, a stirring shaft 32 and a stirring blade group 33. The stirring motor 31 is fixedly mounted on the top of the stirring drum 1. The stirring shaft 32 is located in the stirring drum 1, and its top end is fixed to the driving end of the stirring motor 31. The stirring blade group 33 is fixedly mounted on the outside of the stirring shaft 32. There are two stirring blade groups 33, which are respectively located at the middle and the bottom of the outside of the stirring shaft 32. The stirring blade group 33 includes two inclined blades 331, and the inclination directions of the two blades 331 are opposite. A reinforcing rod 332 is fixedly mounted between the blade 331 and the stirring shaft 32.

[0054] It should be noted that when the stirring part 3 is in use, the stirring motor 31 rotates, which can drive the stirring shaft 32 to rotate together, and the stirring blade group 33 rotates along with the stirring shaft 32 to stir the flour mixture in the stirring drum 1. By rotating the two stirring blade groups 33 in the middle and lower parts respectively, the flour mixture can have sufficient range of movement, avoiding the accumulation of the flour mixture at the bottom and promoting rapid mixing of the flour mixture.

[0055] Please refer to Figures 7 to 11 In order to further speed up the mixing speed of wheat flour and high-fiber materials and improve the accumulation problem at the bottom of the mixing drum 1, the present invention is improved on the basis of the above scheme. The specific scheme is as follows: the discharge mechanism 42 also includes a mixing auxiliary component 423, the mixing auxiliary component 423 includes an extrusion block 4231 and five lifting members, the extrusion block 4231 is fixedly installed at the bottom end of the mixing shaft 32, and the five lifting members are correspondingly arranged on the top of the five blocking plates 4213, and the lifting members include a flip plate 4232, a matching gear 4233, matching rack 4234, return spring 4235 and contact block 4236, the top surface of the blocking plate 4213 is respectively provided with a contraction groove 4237 and a slide groove 4238, the flip plate 4232 is movably embedded in the contraction groove 4237, one end of the flip plate 4232 is rotatably connected to the contraction groove 4237, the matching gear 4233 is fixed to the rotating end of the flip plate 4232, the matching rack 4234 is slidably set in the slide groove 4238, one end of the matching rack 4234 is connected to the matching gear 4 233 is engaged, and the return spring 4235 is fixedly installed between the matching rack 4234 and the inner wall of the slide groove 4238. The contact block 4236 is located at the top of the blocking plate 4213, and one end of the contact block 4236 is fixed to the top of the matching rack 4234; an elastic sleeve 4239 is fixedly installed between the bottom surface of the flip plate 4232 and the inner bottom wall of the contraction groove 4237. When the flip plate 4232 is flipped downward, the elastic sleeve 4239 is stretched. The elastic sleeve 4239 can be made of rubber and is shaped like the blocking plate 4213. Correspondingly, the gap between the flip plate 4232 and the shrinkage groove 4237 is blocked, and the bottom surface of the blocking plate 4213 is provided with an air hole 42310 extending into the shrinkage groove 4237, and a baffle 42311 is fixedly installed on the upper end of the rack 4234. The bottom of the baffle 42311 slides in fit with the top surface of the blocking plate 4213, and the cross-sectional area of ​​the baffle 42311 is greater than or equal to the cross-sectional area of ​​the slide groove 4238, so that the baffle 42311 can completely cover the top opening of the slide groove 4238.

[0056] It should be noted that the use process of the above-mentioned mixing auxiliary component 423 is as follows: when the stirring shaft 32 rotates, the extrusion block 4231 can be driven to rotate. When the end of the extrusion block 4231 rotates and contacts the end of the first contact block 4236, an extrusion force begins to be generated on the contact block 4236, so that the contact block 4236 begins to slide linearly along the slide groove 4238 and squeezes the return spring 4235, and the matching rack 4234 slides with the contact block 4236 and drives the matching gear 4233 to rotate. The rotation of the matching gear 4233 can drive the flip plate 4232 to start flipping upward and gradually move away from the contraction groove 42 37, and the elastic sleeve 4239 is stretched by the flip plate 4232 to prevent the external flour mixture from entering the contraction groove 4237. At the same time, when the flip plate 4232 is flipped upward, the external air enters through the air hole 42310 to maintain the air pressure inside the contraction groove 4237 constant. By flipping the flip plate 4232 upward, the flour mixture on its top surface can be thrown upward, so that the flour mixture moves close to the middle stirring shaft 32. When the extrusion block 4231 rotates and passes through the first contact block 4236 to separate, under the elastic force of the return spring 4235, the contact block 4236 and the matching rack 4234 are The gear 4233 and the flip plate 4232 are turned downwards and reset, and the gas in the contraction groove 4237 is discharged through the air hole 42310 again. When the extrusion block 4231 contacts the next contact block 4236, the corresponding flip plate 4232 repeats the above action. When the gear rack 4234 slides, the baffle plate 42311 can be driven to slide on the top of the slide groove 4238 at the same time. Since the baffle plate 42311 always covers the top of the slide groove 4238, the flour on the top surface of the blocking plate 4213 can be prevented from mixing and entering the slide groove 4238, so as to avoid affecting the normal sliding of the gear 4233. In this way, through the continuous rotation of the stirring shaft 32, the flip plates 4232 at different positions can be driven to flip respectively, so that the contact opportunity between the bottom flour mixture and the stirring shaft 32 can be increased, and the activity range of the flour mixing can be increased; and the present invention realizes the linkage effect between the discharge part 4 and the stirring part 3 by further setting a mixing auxiliary component 423 for use with the stirring shaft 32, and can realize the mixing and stirring function of the flour at the bottom in the process of the rotation of the stirring shaft 32, further speeding up the mixing speed of the flour mixture, and avoiding the problem of uneven mixing due to the accumulation of the flour mixture at the bottom.

[0057] Please refer to Figure 12 to Figure 13In order to improve the problem of high-fiber flour being adsorbed on the inner wall of the discharge hopper 41 during discharge and to speed up the discharge speed, the present invention further optimizes the above scheme, specifically: the discharge mechanism 42 also includes five knocking mechanisms 424, the number of which is not limited to five, should be less than or equal to five, and can be adjusted according to actual use requirements, the knocking mechanism 424 includes a push plate 4241, a knocking body 4242, a connecting spring 4243 and a supporting spring 4244, the push plate 4241 is rotated and arranged It is installed on the bottom surface of the blocking plate 4213, and the push plate 4241 can only rotate to one side. The push plate 4241 follows the movement of the blocking plate 4213 and does not rotate when it contacts the top of the knocking body 4242. The support spring 4244 is fixed between the push plate 4241 and the blocking plate 4213. The knocking body 4242 is rotatably installed on one side of the inner wall of the discharge hopper 41. The connecting spring 4243 is fixed between the knocking body 4242 and the inner wall of the discharge hopper 41. The push plate 4241 and the knocking body 4242 remain aligned.

[0058] It should be noted that when the knocking mechanism 424 is in use, the discharge mechanism 42 is adjusted to the open state, and the push plate 4241 moves together with the blocking plate 4213 to approach the top of the knocking body 4242. When the push plate 4241 contacts the top of the knocking body 4242, as the blocking plate 4213 continues to move outward, the push plate 4241 drives the knocking body 4242 to rotate, and the connecting spring 4243 is synchronously compressed during the rotation of the knocking body 4242. The bottom end of the knocking body 4242 is also separated from the inner wall of the discharge hopper 41. Before the blocking plate 4213 moves to the maximum open state, the push plate 4241 is separated from the top of the knocking body 4242. At this time, the knocking body 4242 is quickly rotated and reset under the elastic force of the connecting spring 4243, and finally the bottom end of the knocking body 4242 strikes the inner wall of the discharge hopper 41 once, and the knocked discharge hopper 41 produces a vibration effect, which can promote the surface adsorbed on the inner wall of the discharge hopper 41 to The powder mixture flows downward and is finally separated from the inner wall of the discharge hopper 41. After the blocking plate 4213 reaches the maximum opening state, the blocking plate 4213 can be driven to move and contract by driving the motor 4221 to rotate in the opposite direction. When the push plate 4241 contacts the top of the knocking body 4242 again, the knocking body 4242 exerts an extrusion force on the push plate 4241, causing the push plate 4241 to start rotating close to the blocking plate 4213 and squeeze the support spring 4244, so that the push plate 4241 can The knocking body 4242 can pass through the top of the knocking body 4242 smoothly, and then the driving motor 4221 rotates forward again, driving the push plate 4241 to generate an extrusion force on the knocking body 4242 again, so that the knocking body 4242 rotates again, and then knocks the inner wall of the discharge hopper 41. Repeating the operation can achieve repeated knocking on the inner wall of the discharge hopper 41, promote the separation of the high-fiber flour adsorbed on the inner wall of the discharge hopper 41 from the inner wall of the discharge hopper 41, and solve the problem of high-fiber flour adhesion during discharge. It can be seen that the knocking mechanism 424 set by the present invention achieves the knocking effect on the discharge hopper 41 by cooperating with the discharge mechanism 42, and accelerates the discharge speed of the high-fiber flour.

A person skilled in the art may make many forms inspired by the present embodiment, all of which are protected by the present embodiment.
