Description

Technical Field

[0001] The invention relates to the field of drying equipment, in particular to a drying device for producing oatmeal and a process thereof. Background Art

[0002] Oat drying is a key step in the oat production process. Its purpose is to reduce the moisture content in the oats to facilitate storage, transportation and improve product stability. Before drying, the oats need to be conditioned to ensure the consistency of the overall oat drying. Then, a commonly used horizontal drying device is used to dry the oats in batches.

[0003] Drying equipment can be divided into same-end inlet and outlet and two-end inlet and outlet according to the different positions of the material inlet and outlet. During batch drying, the oats in the two-end inlet and outlet drying equipment are transported from one end to the other end, and its disturbance leaves are mostly in an inclined and surrounding form, which makes the drying drum continuously push the material forward when rotating. Under a fixed working time, the material stays in the drum for a shorter time, affecting the drying effect. It is necessary to configure a drying equipment with straight disturbance leaves as a transfer; while in the drying equipment with same-end inlet and outlet, the drying drum pushes the material to one end during drying, and then reverses and transports the material back to the feed port, but discharges it from the discharge port. In this form, the material drying time is longer, but because the drying drum rotates forward and reversely, the material will first accumulate at the end of the forward stroke for a period of time before being driven and transported back, resulting in uneven drying of some materials, and easy occurrence of dry solidification and coking and wet adhesion on the disturbance leaves, affecting the drying effect.

[0015] In the second step, when the oats are about to be transported to the discharge area, the drum assembly enters the second state, the second auxiliary drum rotates at a speed lower than the second drum, and the first auxiliary drum rotates at a speed higher than the first drum, so that the first blade and the second blade in the auxiliary drum structure and the main drum structure are combined to the required position to form a flat stirring state, stirring the oats in the drum assembly without transporting them, so that the oats are sufficiently dried in the drum assembly;

[0017] In the fourth step, materials are put in gradually. After the old batch of dried oats are transported out, the new oats move quickly to the discharge area and then continue from the second step.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides a main cylinder structure and a secondary cylinder structure, and cooperates with the main cylinder structure to separately provide the two ends of the disturbance blade in the drum assembly to the main cylinder structure and the secondary cylinder structure, and the two ends of the disturbance blade are nested and connected with the second blade plate through a connecting plate. When in use, the secondary cylinder structure and the main cylinder structure are differentially rotated to switch the disturbance blade between a linear flat stirring state and a curved conveying state in the drum assembly, thereby changing the retention and conveying state of oats in the drum assembly, allowing the oats to be dried in a unidirectional drying direction, avoiding the accumulation of oats in corners, and thus obtaining a better drying effect.

[0020] 2. The present invention installs the disturbance blade on the drum assembly in a swinging manner, and provides a guide plate on the outer side of the drum assembly to guide the disturbance blade. By setting the guide groove on the guide plate, the disturbance blade starts to swing upward in the state of carrying the most materials near the horizontal line to form a hook-shaped structure similar to a forklift bucket, thereby reducing the height of the dumped materials, allowing the materials to be transported to a higher position and dumped slowly when the disturbance blade gradually rotates upward, so that the oats driven by stirring are distributed more evenly, and a better drying effect is obtained;

[0021] At the same time, a traction assembly is arranged on the outside of the drum assembly to pull the disturbance leaf entering the confluence groove, and the width of the confluence groove is set so that the moment the disturbance leaf is reset by the tension spring is not restricted by the confluence groove, thereby driving the outward arm to quickly hit the limit shaft, causing the disturbance leaf to vibrate and shake off some residual, sticky oats to avoid affecting the drying effect.

[0022] 3. The present invention sets a one-way valve on the second blade to guide the air pressure state of the connecting plate in the second blade. When the connecting plate is pulled out from the second blade, air mainly enters from the outside of the drum assembly. When the connecting plate is reset and inserted back into the second blade, air is squeezed out from the gap between the connecting plate and the second blade, impacting the gap outward to prevent oats from being blocked in the gap between the connecting plate and the second blade.

[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Examples, such as Figure 1-Figure 7 As shown: The present invention provides a drying device for producing oatmeal and a process thereof. The drying device structure includes a machine body 1 and a roller assembly 2 horizontally mounted on the machine body 1. The main body of the roller assembly 2 is a cylindrical roller structure. The machine body 1 is provided with a supporting wheel 12 for supporting the roller assembly 2. The roller assembly 2 is driven to rotate by a driving assembly 5. A corresponding annular structure is also added to the roller assembly 2 to cooperate with the supporting wheel 12 to prevent the roller assembly 2 from moving during rotation. A disturbance blade 3 is provided in the roller assembly 2 for disturbing and stirring the oat material, and a hot air pipe 4 is provided on the machine body 1. The hot air pipe 4 is connected to an electric heating device such as a fan with an electric heating wire. It is known to those skilled in the art that the air outlet of the hot air pipe 4 extends into the roller assembly 2 to disturb the roller assembly 2 is used to transport hot air flow in the drum assembly 2 to dry the oats in the drum assembly 2. The head of the machine body 1 is set as a feeding area and is provided with a feeding hopper 11, and the tail is set as a discharging area. The hot air flow is transported from the discharging area to the drum assembly 2 and to the top of the drum assembly 2 to avoid causing air flow to disturb the oats at the bottom. When the disturbance leaves 3 of the drum assembly 2 disturb the oats, the drum assembly 2 drives the disturbance leaves 3 to switch between a straight line and a curved shape in this embodiment, thereby changing the retention and transportation state of the oats in the drum assembly 2, and causing the disturbance leaves 3 to vibrate to avoid the oats adhering to the disturbance leaves 3 and accumulating, so that the oats are dried in a unidirectional drying direction. For this purpose, it mainly includes two parts: the drum assembly 2 and the disturbance leaves 3 structure;

[0035] First, for the roller assembly 2, the roller assembly 2 includes a main cylinder structure and a secondary cylinder structure connected by a matching ring 26. The matching ring 26 is used to roughly limit the gap between the main cylinder structure and the secondary cylinder structure. A wear-resistant metal ring material can be used to slide with the main cylinder structure and the secondary cylinder structure. It will not be repeated here. The main cylinder structure starts from the feed inlet and includes a first roller 21 and a second roller 22 in sequence. A secondary cylinder structure is provided between the first roller 21 and the second roller 22. The secondary cylinder structure includes a first secondary cylinder 24 and a second secondary cylinder 25 in sequence. The first roller 21 and the second roller 22 are driven by the driving assembly 5. The disturbance blade 3 rotates in the same direction, the disturbance blade 3 includes a first blade plate 31 and a second blade plate 32, the first blade plate 31 and the second blade plate 32 are respectively arranged on the first roller 21 and the first sub-tube 24 and on the second roller 22 and the second sub-tube 25, the first blade plate 31 and the second blade plate 32 are connected by a connecting plate 33 to form a long strip structure in the roller assembly 2, and the connecting plate 33 is elastic. In this embodiment, the long strip structure formed by the first blade plate 31, the connecting plate 33 and the second blade plate 32 is respectively arranged in the space formed by the first roller 21 and the first sub-tube 24, the second roller 22 and the second sub-tube 25;

[0036] Moreover, the roller assembly 2 is also provided with a gear ring 23 added to the roller assembly 2. It can be known that the gear ring 23 structure will not affect the understanding of the shape of the roller assembly 2. The first roller 21, the second roller 22, the first sub-tube 24 and the second sub-tube 25 are all provided with gear rings 23. The driving assembly 5 includes a first motor 51 for driving the main tube structure to rotate and a second motor 54 for driving the sub-tube structure to rotate. The first motor 51 is provided with a rotating shaft 52 and the rotating shaft 52 is provided with two main driving gears 53 for driving the first roller 21 and the second roller 22. The second motor 54 is provided with two and both are provided with sub-driving gears 55 for driving the first sub-tube 24 and the second sub-tube 25 respectively.

[0037] The state of the disturbance blade 3 includes at least two states: a horizontal stirring state and a conveying state. The disturbance blade 3 in the horizontal stirring state has a straight line between its first blade 31, the second blade 32 and the connecting plate 33. The disturbance blade 3 in the conveying state has a connecting plate 33 between its first blade 31 and the second blade 32 undergoing elastic bending deformation, and the bending angle can drive the material inside the drum assembly 2 to be conveyed from the inlet to the discharge structure in the rotation direction of the drum assembly 2.

[0038] It should be noted that an inner cavity 32a is provided in the second blade 32 and an opening of the inner cavity 32a is provided on the side of the second blade 32. One end of the connecting plate 33 is fixed to the first blade 31 and the other end is nested in the second blade 32. When the connecting plate 33 between the first blade 31 and the second blade 32 undergoes bending elastic deformation, the connecting plate 33 is pulled out from the second blade 32, and when the connecting plate 33 is reset to the flat stirring state, it is inserted into the second blade 32. It can be seen that the connecting plate 33 can adopt a food-grade iron bar or a food-grade plastic structure, and a wear-resistant coating or a solid self-lubricating material coating, such as a nano coating, is coated at the nesting point of the connecting plate 33 and the second blade 32 to reduce the friction between the connecting plate 33 and the second blade 32.

[0039] In order to make the disturbance blade 3 in the drum assembly 2 undergo a morphological transformation, the state of the first sub-drum 24 and the second sub-drum 25 in this embodiment includes a first state and a second state: in the first state, the first motor 51 and the second motor 54 drive the sub-drum structure and the main drum structure to rotate synchronously in the same direction; in the second state, the sub-drum structure and the main drum structure rotate differentially, specifically, the second motor 54 drives the second sub-drum 25 to rotate at a speed greater than or less than the second drum 22, and the second motor 54 drives the first sub-drum 24 to rotate at a speed less than or greater than the first drum 21, and the second state is completed when the first blade plate 31 and the second blade plate 32 in the sub-drum structure and the main drum structure are staggered or merged to the required position, and then the sub-drum structure and the main drum structure enter the first state and rotate synchronously in the same direction;

[0040] It can be seen that the first state and the second state represent the speed state difference between the auxiliary cylinder structure and the main cylinder structure. When the equipment is in use, the conveying state of the disturbance blade 3 is used as the starting point to drive the newly poured oats to be conveyed in the drum assembly 2. When the conveying has not yet reached the discharge area, the drum assembly 2 enters the second state, allowing the second auxiliary cylinder 25 to rotate at a speed lower than the second drum 22, and the first auxiliary cylinder 24 to rotate at a speed higher than the first drum 21, so that the first blade 31 and the second blade 32 in the auxiliary cylinder structure and the main cylinder structure are merged to the required position to form a flat stirring state. When the disturbance blade 3 in the flat stirring state drives the oats to be sufficiently dried in the drum assembly 2, the second auxiliary cylinder 25 rotates at a speed higher than the second drum 22, and the first auxiliary cylinder 24 rotates at a speed lower than the first drum 21, so that the first blade 31 and the second blade 32 in the auxiliary cylinder structure and the main cylinder structure are staggered to the required position to form a conveying state, and the oats are conveyed out.

[0041] Second, for the structure of the disturbance blade 3, the state of the disturbance blade 3 also includes a tilted state. For this purpose, the disturbance blade 3 is swingably mounted on the drum assembly 2. The machine body 1 is provided with a guide plate 6 on the outside of the drum assembly 2 for guiding the swing angle of the disturbance blade 3. The drum assembly 2 is provided with a traction assembly 7 on the outside of the drum assembly 2 for driving the disturbance blade 3 to reset and vibrate. Specifically, the drum assembly 2 is provided with an opening at the disturbance blade 3. The top ends of the first blade plate 31 and the second blade plate 32 are provided with an outrigger arm 3a extending upward to the outside of the opening of the drum assembly 2. The first blade plate 31 and the second blade plate 32 are hingedly connected to the drum assembly 2 through the outrigger arm 3a. The drum assembly 2 is provided with a hinge seat 36. The outrigger arms 3a of the first blade plate 31 and the second blade plate 32 are further connected to the drum assembly 2 through the hinge seat 36, and the hinge connection point is located on the outside of the drum assembly 2.

[0042] It should be noted that a barrier sleeve 37 connected to the outwardly extending arms 3a of the first blade 31 and the second blade 32 is provided at the opening of the drum assembly 2 for closing the opening. It is known to those skilled in the art that the barrier sleeve 37 can be made of an inorganic polymer colloidal material formed by polycondensation of silicate, i.e., food-grade silica gel;

[0043] At the same time, a guide groove for guiding is provided on the guide plate 6, and the guide includes an arc-shaped base groove 6a and an arc-shaped inclined groove 6b with a diameter smaller than the base groove 6a. The base groove 6a and the inclined groove 6b are transitionally connected by a confluence groove 6c. A guide wheel 35 is provided on the outrigger arm 3a. The guide wheel 35 cooperates with the guide groove of the guide plate 6 so that the outrigger arm 3a is guided by the guide groove and tilted when following the rotation of the roller assembly 2, and is tilted by the pressure of the inclined groove 6b when encountering the inclined groove 6b during rotation, so that the guide wheel 35 is blocked and moves in the direction opposite to the rotation direction of the roller assembly 2. Therefore, at the other end of the hinge connection point, the first blade 31 and the second blade 32 will swing and tilt in the rotation direction of the roller assembly 2;

[0044] Specifically, the angle between the starting point of the tilting groove 6b in the rotation direction of the drum assembly 2 and the connecting line of the center of the drum assembly 2 and the horizontal line is -15°~+15°, and the front of the rotation direction of the drum assembly 2 is taken as the positive direction. After crossing the horizontal line, the disturbance leaf 3 usually continues to rotate upward and begins to enter the state of dumping materials. The disturbance leaf 3 starts to swing upward in the state of carrying the most materials near the horizontal line to form a hook-shaped structure similar to a forklift bucket, thereby reducing the height of the dumped materials, allowing the materials to be slowly dumped and maintaining more materials to be transported to a higher position.

[0045] Moreover, an extension arm 34 is provided on the outrigger arm 3a, and the extension arm 34 is an extension of the outrigger arm 3a structure. The extension arm 34 is bent or curved and is bent or curved in a direction opposite to the rotation direction of the roller assembly 2. The guide wheel 35 is provided at the end of the extension arm 34 on the outrigger arm 3a, and the traction assembly 7 includes a fixed seat 71 and a limiting shaft 72 mounted on the fixed seat 71. A tension spring 73 is fixed on the limiting shaft 72 or the fixed seat 71, and the other end of the tension spring 73 is connected to the first blade 31 and the second blade 3 2 is connected to the outrigger arm 3a of the first blade 31 and the second blade 32, the tension spring 73 is used to provide a pulling force to drive the outrigger arms 3a of the first blade 31 and the second blade 32 to break away from the tilting groove 6b and return to the base groove 6a, the limit shaft 72 is used to limit the position where the outrigger arms 3a of the first blade 31 and the second blade 32 are reset, and the arc angle of the arc-shaped tilting groove 6b is 90°~135°, so that after the disturbance blade 3 has finished pouring the oats, it is driven by the tension spring 73 to return from the tilting groove 6b to the base groove 6a above the drum assembly 2;

[0046] It should be noted that the width of the confluence groove 6c at the end of the inclined groove 6b is greater than the width of the base groove 6a and the inclined groove 6b. The outward arm 3a of the confluence groove 6c located at the end of the inclined groove 6b is pulled by the tension spring 73 to swing, and the path range generated does not interfere with the confluence groove 6c. Therefore, when the tension spring 73 drives the disturbance leaf 3 to reset, it can be not restricted by the confluence groove 6c at the moment of reset, and quickly hit the limit shaft 72, causing the disturbance leaf 3 to vibrate.

[0047] In summary, in the specific implementation, the following drying processes are included:

[0048] In the first step, when the device is used, the conveying state of the disturbance blade 3 is used as the start, oats are poured in, and the drum assembly 2 rotates to drive the newly poured oats to be conveyed in the drum assembly 2;

[0049] In the second step, when the oats are about to be transported to the discharge area, the drum assembly 2 enters the second state, and the second auxiliary drum 25 rotates at a speed lower than the second drum 22, and the first auxiliary drum 24 rotates at a speed higher than the first drum 21, so that the first blade 31 and the second blade 32 in the auxiliary drum structure and the main drum structure are combined to the required position to form a flat stirring state, and the oats are stirred in the drum assembly 2 without being transported, so that the oats are sufficiently dried in the drum assembly 2;

[0050] In the third step, when the disturbance blades 3 in the flat stirring state drive the oats to be sufficiently dried in the drum assembly 2, the second auxiliary drum 25 rotates at a speed greater than the second drum 22, and the first auxiliary drum 24 rotates at a speed less than the first drum 21, so that the first blades 31 and the second blades 32 in the auxiliary drum structure and the main drum structure are staggered to the required positions to form a conveying state, and the oats are conveyed out;

[0051] In the fourth step, materials are put in gradually. After the old batch of dried oats are transported out, the new oats move quickly to the discharge area and then continue from the second step.

[0052] During the execution of the above process, a basic step is also included that is integrated into each step. In the basic step, the drum assembly 2 rotates following the steps of the above drying process. During the rotation, the guide wheels 35 on the outrigger arms 3a of the first blade plate 31 and the second blade plate 32 move in the base groove 6a. At this time, the first blade plate 31 and the second blade plate 32 are on the radius line of the drum assembly 2, that is, on the line connecting the hinge connection point of the first blade plate 31 and the second blade plate 32 and the center of the drum assembly 2. The disturbance blade 3 moves in the base groove 6a in this posture.

[0053] When the guide wheel 35 passes through the confluence groove 6c and enters the sloping groove 6b, it is pressed by the sloping groove 6b, so that the guide wheel 35 is blocked and moves in the direction opposite to the rotation direction of the drum assembly 2. Therefore, at the other end of the hinge connection point, the first blade 31 and the second blade 32 will swing and tilt in the rotation direction of the drum assembly 2, so that the disturbance leaf 3 starts to swing upward in the state of carrying the most materials near the horizontal line to form a hook-shaped structure similar to a forklift bucket, thereby reducing the height of the dumped materials, allowing the materials to slowly dump when the disturbance leaf 3 gradually rotates upward and keep more materials to be transported to a higher position;

[0054] When the guide wheel 35 moves to the end in the inclined groove 6b and is about to move out of the inclined groove 6b, the guide wheel 35 moves to the confluence groove 6c at the end of the inclined groove 6b. At this point, the tension spring 73 drives the disturbance leaf 3 to reset and is not restricted by the confluence groove 6c, thereby driving the outward arm 3a to quickly hit the limit shaft 72, causing the disturbance leaf 3 to vibrate and shake off some residual, sticky oats to avoid affecting the drying effect.

[0055] In the present embodiment, more than that, a one-way valve 38 connected to the inner cavity 32a is provided on the second blade 32, and the air intake direction of the one-way valve 38 is from the outside of the inner cavity 32a to the inside of the outer cavity; an air separator 33a is embedded in one end of the connecting plate 33 embedded in the second blade 32, and a plurality of air ports 33b are provided on the side of the air separator 33a contacting the inner wall of the inner cavity 32a. Therefore, when the connecting plate 33 is pulled out of the second blade 32, a small amount of air is allowed to enter the inner cavity 32a through the air ports 33b, while most of the air enters the inner cavity 32a through the one-way valve 38, thereby balancing the air pressure of the inner cavity 32a after the connecting plate 33 is pulled out. After the connecting plate 33 is inserted into the second blade 32, the gas is completely squeezed out from the air ports 33b, and the gap between the connecting plate 33 and the second blade 32 is impacted outward, so as to prevent oats from being blocked in the gap between the connecting plate 33 and the second blade 32.

[0056] It should be noted that the size and shape of the air port 33b can be selected according to actual conditions. A structure with a small opening at one end near the outer side of the inner cavity 32a and a large opening near the inner side of the inner cavity 32a can be adopted to allow most of the air flow to enter through the one-way valve 38.

[0057] Moreover, in this embodiment, the inner cavity 32a extends outward from the outrigger arm 3a, and the one-way valve 38 is installed on the outrigger arm 3a and is located on the outside of the drum assembly 2, so that the inner cavity 32a can take in air from the outside of the drum assembly 2 to avoid blockage caused by the interaction with the oats in the drum assembly 2.

[0058] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
