Description

Technical Field

[0001] The invention relates to the technical field of gluten processing, in particular to wheat drying equipment for gluten processing. Background Art

[0002] Gluten, also known as active gluten flour and wheat gluten protein, is a light yellow powdery natural grain protein extracted from wheat through deep processing. Gluten is an excellent dough improver and is widely used in the production of bread, noodles, and instant noodles. It is also widely used in the meat, aquatic products, and beverage industries. The raw material for gluten production is wheat. Before deep processing of the raw material to extract gluten, the wheat raw material needs to be removed from impurities, cleaned, and dried. The drying process of the wheat raw material relies on drying equipment.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The wheat drying equipment for gluten processing is provided with an inner drying drum and an outer drying drum. The wheat entering from the feed hopper enters the inner drying drum through a movable seat, and the first gear is driven to rotate by a first motor. The first gear drives the inner drying drum to rotate relative to the outer drying drum through a gear ring, so that the wheat in the inner drying drum is evenly preheated by hot air. The preheated wheat is transported by an inner spiral blade and enters the outer drying drum from a feed port. When the inner drying drum is preheating the next batch of wheat, it rotates and drives the outer spiral blade to stir the wheat in the outer drying drum, so that the wheat is evenly heated and dried. When the inner drying drum rotates, the inner wheat can be preheated by drum drying while the outer wheat is subjected to stirring secondary drying, so as to achieve the effect of synchronously drying two batches of wheat at the same time. In addition, the preheating step-by-step drying method is adopted, so that two consecutive batches of wheat can be dried at the same time, and the time required for wheat drying is shortened.

[0017] 2. The wheat drying equipment for gluten processing is provided with a material transfer mechanism. After the wheat is preheated in the inner drying drum, the third motor drives the screw to rotate, and the screw drives the rectangular rod to move back and forth in the rectangular hole through the screw hole. The rectangular rod pulls the blocking plug out of the discharge port, canceling the blocking effect on the discharge port, so that the inner cavity of the inner drying drum is connected with the inner cavity of the outer drying drum, and then the inner spiral blade squeezes the wheat out of the discharge port, so as to automatically complete the transfer of wheat from the preheating state to the drying state, thereby increasing the degree of automation of the equipment.

[0018] 3. The wheat drying equipment for gluten processing is provided with a feeding mechanism. Wheat is poured into the lowest storage trough on the front side of the feeding turntable. The second motor drives the second gear to rotate. The second gear drives the feeding turntable to rotate relative to the base through the tooth pattern, so that the storage trough carrying wheat is transferred upward with the feeding turntable and directly moved to the top of the feed hopper. After the storage trough is opened, the wheat inside falls into the feed hopper due to gravity, so as to realize the effect of automatic feeding of the feed hopper above the movable seat. Moreover, multiple storage troughs are fed in sequence, which can effectively avoid the blockage of wheat feed.

[0019] 4. The wheat drying equipment for gluten processing is provided with a movable rod and a corrugated rubber pad. When wheat is added to the storage trough, the loading turntable drives the movable rod and the shifting block to rotate until the shifting block moves to the right side of the second protrusion. At this time, the second protrusion blocks and restricts the shifting block, and the shifting block continues to rotate with the loading turntable, so that the shifting block drives the movable rod to move in the slide groove toward one side of the fixed rod. The movable rod pushes the corrugated rubber pad to fold and shrink, and the spring is compressed, and the storage trough is opened to load wheat. After loading is completed, the loading turntable continues to rotate to drive the movable rod to move until the shifting block is deformed and passes over the second protrusion, and the spring rebounds to push the movable rod to reset, and the movable rod pulls the corrugated rubber pad to close the storage trough, thereby realizing the automatic opening and closing effect of the storage trough.

[0031] like Figures 1 to 7As shown, the wheat drying equipment for gluten processing in this embodiment comprises an outer drying drum 1, a discharge port 11 provided at the bottom of the outer drying drum 1, a discharge valve 12 installed at the bottom of the discharge port 11, and a support leg 13 installed on the lower surface of the outer drying drum 1. An inner drying drum 2 is installed at the center of the inner part of the outer drying drum 1 for preheating the wheat for primary drying. The outer drying drum 1 is used for secondary drying to achieve step-by-step drying. The inner drying drum 2 extends from the front side of the outer drying drum 1 and is connected to a movable seat 3. A feeding mechanism 4 is installed on the outer side of the movable seat 3 for conveying the wheat at a lower position to a higher position and putting it into the inner drying drum 2. Ventilation holes 21 are provided on the side wall of the inner drying drum 2. The number of ventilation holes 21 is several, and the side wall of the inner drying drum 2 is equidistantly arranged in the circumferential direction, so as to connect the hot air in the inner drying drum 2 with the inner part of the outer drying drum 1. The aperture of the ventilation holes 21 is smaller than that of the wheat particles to avoid blockage of the ventilation holes 21. The outer side wall of the inner drying drum 2 is connected to an outer spiral blade 22 for stirring the wheat and conveying the wheat. To the discharge port 11, the inner wall of the inner drying drum 2 is connected with an inner spiral blade 24 for dispersing the wheat and conveying the wheat to the discharge port 25, the inner wall of the outer drying drum 1 is installed with a connecting rod 14, the connecting rod 14 is used to install the first bearing 23 to maintain the stability of the installation of the inner drying drum 2, and the connecting rod 14 will not block the wheat from being conveyed in the outer drying drum 1, the first bearings 23 are installed between the two ends of the inner drying drum 2 and the inner wall of the outer drying drum 1 and the connecting rod 14, a discharge port 25 is opened on the rear side of the inner drying drum 2 for discharging the wheat in the inner drying drum 2 and entering the outer drying drum 1, a material transfer mechanism 5 is installed inside the discharge port 25 for transferring the wheat from the preheating state to the drying state, a gear ring 26 is provided on the outer wall of the inner drying drum 2 between the movable seat 3 and the outer drying drum 1, the top of the gear ring 26 is meshedly connected with a first gear 27, the rear side of the first gear 27 is connected with a first motor 28, the first motor 28 is installed on the top of the outer drying drum 1, and the shaft end of the first motor 28 is connected to the first gear 27.

[0032] Specifically, a rectangular hole 15 is formed through the center of the rear wall of the outer drying drum 1. Both the outer drying drum 1 and the inner drying drum 2 are hollow cylinders. The inner drying drum 2 is rotatably connected to the outer drying drum 1 via a first bearing 23. The inner drying drum 2 is connected to the inner cavity of the outer drying drum 1 via a ventilation hole 21 and a feed opening 25. The first motor 28 drives the first gear 27 to rotate. The first gear 27 drives the inner drying drum 2 to rotate relative to the outer drying drum via a gear ring 26, so that the wheat in the inner drying drum 2 is evenly preheated by the hot air. At the same time, the hot air passes through the ventilation hole 21 into the outer drying drum 1. When the inner drying drum 2 rotates, it can perform drum-type drying preheating on the inner wheat while performing stirring-type secondary drying on the outer wheat, thereby achieving the effect of synchronously drying two batches of wheat at the same time.

[0033] Furthermore, the inner spiral blades 24 and the outer spiral blades 22 are installed in opposite directions. The inner spiral blades 24 disperse the wheat in the inner drying drum 2, and the outer spiral blades 22 stir the wheat in the outer drying drum 1, so that the wheat is evenly heated and dried. The inner spiral blades 24 convey the material in a backward direction, and the inner spiral blades 24 rotate with the inner drying drum 2 to push the wheat out from the discharge port 25, and the outer spiral blades 22 convey the material in a forward direction, and the outer spiral blades 22 rotate with the inner drying drum 2 to stir the wheat in the outer drying drum 1 and push the wheat to be discharged from the discharge port 11.

[0034] Furthermore, a feed hopper 31 is connected to the top of the movable seat 3, a feed valve 32 is installed at the bottom of the feed hopper 31, a fan 33 is installed on the front side wall of the movable seat 3, and a heating wire 34 is installed on the inner wall of the movable seat 3 behind the fan 33. The heating wire 34 is turned on to generate heat, and the fan 33 blows the air from the external environment into the movable seat 3. The air circulation brings the heat generated by the heating wire 34 into the inner drying drum 2 to dry the wheat with hot air. A first protrusion 35 is connected to the upper surface of one side of the feed hopper 31, and one side of the movable seat 3 is hinged to the front side wall of the outer drying drum 1, which is a common connection structure of traditional drum drying equipment, which is convenient for observing the internal structure of the equipment, and the inner cavity of the movable seat 3 is connected to the inner cavity of the inner drying drum 2.

[0035] Furthermore, the feeding mechanism 4 includes a feeding turntable 41, a second bearing 42 is installed on the outer wall of the feeding turntable 41, a base 43 is connected to the bottom of the second bearing 42, the base 43 is placed on the ground, and a tooth pattern 44 is provided on the outer wall of the feeding turntable 41 in front of the second bearing 42, a second gear 45 is meshed and connected to one side of the feeding turntable 41 through the tooth pattern 44, a second motor 46 is connected to the rear side of the second gear 45, the second motor 46 is installed on the upper surface of the base 43, and the shaft end of the second motor 46 is connected to the second gear 45, a storage trough 47 is provided inside the feeding turntable 41 for storing wheat, so that the wheat is transported upward with the feeding turntable 41 to avoid the trouble of artificial high-altitude feeding, a fixing rod 48 is connected to the inner wall of one side of the storage trough 47, and a slide groove 49 is provided through the side walls of the feeding turntable 41 on the front and rear sides of the storage trough 47. A movable rod 410 is arranged inside, and a corrugated rubber pad 411 is connected between the movable rod 410 and the fixed rod 48, and the corrugated rubber pad 411 is provided with corrugations. When the movable rod 410 moves toward the fixed rod 48, the movable rod 410 applies a thrust to the corrugated rubber pad 411, so that the corrugated rubber pad 411 folds and contracts along the corrugations. A shift block 412 is connected to the side of the movable rod 410 close to the center of the loading turntable 41, and movable blocks 413 are connected to the front and rear sides of the movable rod 410 through the slide groove 49. A fixed block 414 is installed on the loading turntable 41 on one side of the movable block 413, and a spring 415 is connected between the movable block 413 and the fixed block 414. A support frame 416 is installed on the rear side of the base 43, and the support frame 416 is installed on the rear side wall of the base 43. A second protrusion 417 is connected to the bottom of the support frame 416 above the loading turntable 41.

[0036] Furthermore, the loading turntable 41 is in a circular shape, and is rotatably connected to the base 43 via a second bearing 42. There are several storage troughs 47, which are equidistantly arranged circumferentially on the inner wall of the loading turntable 41. The second motor 46 drives the second gear 45 to rotate, and the second gear 45 drives the loading turntable 41 to rotate relative to the base 43 via the tooth pattern 44, so that the storage trough 47 carrying wheat is transferred upward with the loading turntable 41, making wheat loading more labor-saving, and multiple storage troughs 47 are fed in sequence, which can effectively avoid blockage of wheat feed.

[0037] Furthermore, the two sides of the corrugated rubber pad 411 are respectively connected to the fixed rod 48 and the movable rod 410. The front and rear sides of the movable rod 410 pass through the slide groove 49 and form a sliding connection with the slide groove 49. When the movable rod 410 moves away from the fixed rod 48, the corrugated rubber pad 411 is pulled to unfold, so that the corrugated rubber pad 411 blocks the storage trough 47 to prevent wheat from leaking out when the loading turntable 41 carries wheat for transportation.

[0038] Furthermore, the fixed block 414 is welded and fixed to the front and rear side walls of the loading turntable 41, the movable block 413 is slidably connected to the loading turntable 41, and the two ends of the spring 415 are respectively connected to the fixed block 414 and the movable block 413. When the corrugated rubber pad 411 is unfolded, the spring 415 is in a normal tension state, and the shift block 412 contacts the first protrusion 35 and the second protrusion 417 when the loading turntable 41 rotates. The loading turntable 41 drives the movable rod 410 and the shift block 412 to rotate. The first protrusion 35 and the second protrusion 417 block the shift block 412 and restrict the shift block 412 from continuing to rotate with the loading turntable 41, so that the shift block 412 drives the movable rod 410 in the slide groove 49 toward the fixed rod 48. When the loading turntable 41 continues to rotate and drives the movable rod 410 to move, the movable rod 410 is blocked by the corrugated rubber pad 411 and is difficult to continue to move toward the side of the fixed rod 48. Since the top of the shift block 412 is round, under the force of the rotation of the loading turntable 41, the shift block 412 is deformed and passes over the first protrusion 35 and the second protrusion 417. At this time, the spring 415 rebounds and pushes the movable rod 410 to reset. The movable rod 410 pulls the corrugated rubber pad 411 to close the storage trough 47, thereby realizing the automatic opening and closing effect of the storage trough 47.

[0039] Furthermore, the material transfer mechanism 5 includes a plug 51 movably inserted into the inside of the discharge port 25. The plug 51 is cylindrical, and the outer diameter of the plug 51 is compatible with the inner diameter of the discharge port 25. The rear side wall of the plug 51 is connected to a rectangular rod 52, and a screw hole 53 is opened inside the rectangular rod 52. A screw 54 is arranged inside the screw hole 53. The rear side of the screw 54 passes through the rectangular hole 15 and is connected to a third motor 55. A motor bracket 56 is installed at the bottom of the third motor 55. The third motor 55 is installed on the upper surface of the motor bracket 56. The motor bracket 56 is installed on the rear side wall of the outer drying drum 1, and the shaft end of the third motor 55 is connected to the screw 54.

[0040] Furthermore, the screw 54 is threadedly connected with the rectangular rod 52 through the screw hole 53, and the rectangular rod 52 is movably connected to the outer drying drum 1 through the rectangular hole 15. A clamping column is connected to the front side wall of the rectangular rod 52. The clamping column is a cylindrical T-shaped longitudinal section. The clamping column is clamped in the plugging plug 51 to form a rotational connection with the plugging plug 51, so that when the inner drying drum 2 rotates, the plugging plug 51 is driven to rotate. At this time, the plugging plug 51 rotates relative to the rectangular rod 52 through the clamping column, and the rectangular rod 52 is rotationally connected to the plugging plug 51 through the clamping column. The screw 54 is driven to rotate by the third motor 55. The screw 54 drives the rectangular rod 52 to move back and forth in the rectangular hole 15 through the screw hole 53. The rectangular rod 52 pulls the plugging plug 51 out of the discharge port 25, cancels the blocking effect on the discharge port 25, and realizes automatic completion of the transfer of wheat from the preheating state to the drying state.

[0041] The method of using this embodiment is as follows: when the user uses the drying equipment to dry the wheat raw material before processing the gluten, the user first starts the second motor 46, the second motor 46 drives the second gear 45 to rotate, the second gear 45 drives the loading turntable 41 to rotate relative to the base 43 through the tooth pattern 44, the loading turntable 41 drives the movable rod 410 and the shift block 412 to rotate until the shift block 412 moves to the right side of the second protrusion 417, at which time the second protrusion 417 blocks the shift block 412 to restrict the shift block 412 from continuing to rotate with the loading turntable 41, so that the shift block 412 drives the movable rod 410 in the slide groove 49 toward the fixed One side of the fixed rod 48 moves, the movable rod 410 pushes the corrugated rubber pad 411 to fold and shrink, the spring 415 is compressed, the storage trough 47 is opened, and then a certain amount of wheat is poured into the opened storage trough 47, and then the feeding turntable 41 continues to rotate to drive the movable rod 410 to move until the shift block 412 is deformed and passes over the second protrusion 417, and the rebound force of the spring 415 pushes the movable rod 410 to reset, and the movable rod 410 pulls the corrugated rubber pad 411 to close the storage trough 47, and the feeding turntable 41 continues to rotate relative to the base 43, so that the storage trough 47 carrying wheat is transferred upward with the feeding turntable 41 and directly moves to the feed hopper 3 1, at this time, the shift block 412 is on the left side of the first protrusion 35, and the first protrusion 35 blocks and restricts the shift block 412. The shift block 412 continues to rotate with the feeding turntable 41, so that the movable rod 410 moves and pulls the corrugated rubber pad 411 to fold, the storage tank 47 is opened, and the wheat inside falls into the feeding hopper 31 due to gravity. The wheat passes through the movable seat 3 and enters the inner drying drum 2. The first gear 27 is driven to rotate by the first motor 28. The first gear 27 drives the inner drying drum 2 to rotate relative to the outer drying drum through the gear ring 26, so that the wheat in the inner drying drum 2 is evenly preheated by the hot air. After the preheating is completed, the third motor 5 5 drives the screw 54 to rotate, and the screw 54 drives the rectangular rod 52 to move forward and backward in the rectangular hole 15 through the screw hole 53. The rectangular rod 52 pulls the blocking plug 51 out of the discharge port 25 to cancel the blocking effect on the discharge port 25. Then the inner spiral blade 24 squeezes the wheat out of the discharge port 25, and the wheat enters the outer drying drum 1. When the inner drying drum 2 is preheating the next batch of wheat, it rotates and drives the outer spiral blade 22 to stir the wheat in the outer drying drum 1, so that the wheat is evenly heated and dried. After drying, the outer spiral blade 22 pushes the wheat to move to the discharge port 11, and the discharge valve 12 is opened to discharge the wheat.
