Description

Technical Field

[0001] The invention relates to the technical field of agricultural and sideline food processing, in particular to a disc drying device for agricultural and sideline food production. Background Art

[0002] Disc dryer is a highly efficient conductive continuous drying equipment with the characteristics of high thermal efficiency, low energy consumption and small footprint. It continuously inputs materials onto the top drying disc and turns the materials over with the rotation of the rakes and drops them onto the lower drying disc. The drying discs are distributed in alternating sizes and circulate in sequence to achieve continuous drying operations. It is widely used in chemical, pharmaceutical, food, feed and agricultural and sideline product processing industries.

[0003] The rotary feeding mechanism is a feeding mechanism driven by a motor. The motor drives the hopper to rotate, and the discharge end of the hopper can be rotated, so that the conveyed material can be evenly injected into the container along a circular trajectory. As the name suggests, a one-way valve can ensure the one-way input of materials and prevent the reverse flow of materials and gases.

[0004] After searching, the prior art was found: the Chinese patent with announcement number CN221259374U disclosed a disc dryer, which includes a drying chamber, a negative pressure source outside the drying chamber, a first blowing pipe inside the drying chamber, and a plurality of heating plates arranged alternately along the material flow direction; the disc dryer is provided with a plurality of cleaning and drying mechanisms, the cleaning and drying mechanisms include a heating plate and at least one blowing port matched with the heating plate, wherein the blowing port is connected to the first blowing pipe and faces the surface of the heating plate carrying the material; the air inlet of the negative pressure source is connected to the drying chamber to form a negative pressure inside the drying chamber. The disc dryer can clean the drying chamber without using water resources, avoiding manual cleaning with hand-held cleaning tools, thereby improving the cleaning efficiency and cleaning effect.

[0005] In summary, the existing disc dryers mostly use rakes to turn the materials. During the turning process, it is inevitable that the materials will be squeezed and collided, and when the materials are turned, they will also be squeezed. When used for drying thinner agricultural and sideline products, such as tea, sheet medicinal materials, sheet agricultural products, etc., the rotation of the rakes can easily crush the agricultural and sideline products, and there is a certain gap between the rakes and the material tray, which is prone to jamming or leakage, which will not only reduce the integrity of the agricultural and sideline products, but also affect the uniformity of the turning of the materials.

[0006] Most of the existing disc dryers use contact heat conduction in their feed trays, relying on the heat source input into the feed tray to conduct heat to the material. However, for materials with irregular shapes, the contact surface between the material and the feed tray is also irregular, and the size of the contact area will directly affect the efficiency of contact heat conduction. Therefore, the efficiency of contact heating is not high. In addition, the feed tray will block the space inside the disc dryer, resulting in the problem of insufficient air flow inside the dryer, and then the water vapor emitted by the lower drying tray will gather and adhere to the lower surface of the upper drying tray, which is not conducive to the comprehensive discharge of water vapor. For disc dryers that use hot air for drying, the drying tray also blocks the circulation of hot air inside the dryer, resulting in low thermal energy utilization, which is not conducive to energy conservation and emission reduction. Summary of the invention

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figures 1 to 9 The present invention provides the following two embodiments: a disc drying device for producing agricultural and sideline foods, comprising a dryer body 100 and a rotating mechanism 200, the rotating mechanism 200 is arranged inside the dryer body 100, and the dryer body 100 is provided with a first drying mechanism 300 and a second drying mechanism 400 which are staggeredly distributed, and a driving mechanism 210 is arranged at the bottom end of the rotating mechanism 200, and the driving mechanism 210 includes a motor and a driving gear, which is used to drive the rotating mechanism 200 to rotate.

[0046] Embodiment 1:

[0047] See also Figure 1 , Figure 3 and Figure 4 , the first drying mechanism 300 and the second drying mechanism 400 are both provided with a material tray 800. The material tray 800 is made of elastic mesh material, specifically silicone rubber material. Silicone rubber is used as the main body of the material tray 800, which has excellent high temperature resistance and can maintain elasticity in a temperature environment of -60-250°C. Silicone rubber can be used as a food-grade material, which is non-toxic, odorless and degradable, and can be used in the field of food processing. The size of the mesh can be determined according to the actual needs of use to facilitate the drying operation of different agricultural and sideline products. When applied to tea drying, the mesh diameter is 1-2mm; when applied to medicinal material drying, the mesh diameter is 2-5mm; when applied to agricultural and sideline product drying, the mesh diameter can be 2-10mm. Adaptability selection can be made according to the size of the drying material.

[0048] The first drying mechanism 300 and the second drying mechanism 400 are both provided with a positioning mechanism 500 and a turning mechanism 600 on their surfaces;

[0049] The positioning mechanism 500 includes a support rod 510, which is inserted into the first drying mechanism 300 and the second drying mechanism 400. The positioning mechanism 500 is used to support the inner side of the first drying mechanism 300 and the second drying mechanism 400, so that the first drying mechanism 300 and the second drying mechanism 400 can maintain the tension of the material tray 800. The surface of the end of the support rod 510 facing away from the rotating mechanism 200 is provided with a lifting mechanism 700.

[0050] See also Figure 6 and Figure 7 The flipping mechanism 600 includes a spreading rod 610 and an air pipe 620. The surface of the spreading rod 610 is provided with evenly distributed air grooves 611. The rotating mechanism 200 is connected with the inside of the spreading rod 610 through the air pipe 620. A sleeve 613 is embedded and installed on the surface of one end of the spreading rod 610. The air pipe 620 is rotatably sleeved on the surface of the sleeve 613. The interior of the sleeve 613 is respectively connected with the interior of the spreading rod 610 and the air pipe 620. The hot air transmitted inside the rotating mechanism 200 enters the inside of the spreading rod 610 through the air pipe 620 and is ejected from the air groove 611 on the surface of the spreading rod 610. After the hot air flow is ejected from the air groove 611, the air flow passes through the material tray 800 and acts on the material on the surface of the material tray 800. The kinetic energy of the air flow can be used to blow up the material, thereby realizing the flipping of the material. Combined with the rotation of the spreading rod 610, the material can be evenly spread on the surface of the material tray 800. In addition, the hot air ejected from the air groove 611 is in close contact with the material, thereby realizing comprehensive contact between the hot air and the material, effectively increasing the efficiency of heating and drying, thereby accelerating the drying speed.

[0051] The surface of the spreading rod 610 is in contact with the surface of the material tray 800, and the driving mechanism 210 drives the rotating mechanism 200 to rotate. The rotating mechanism 200 simultaneously drives the flipping mechanism 600 below the first drying mechanism 300 and the second drying mechanism 400, and the spreading rod 610 rotates along the lower surface of the material tray 800. The spreading rod 610 bulges the surface of the material tray 800, and cooperates with the rotation of the spreading rod 610 to achieve periodic bulging of the surface of the material tray 800. The raised part of the material tray 800 moves to disperse the material on the surface of the material tray 800, which not only effectively avoids direct contact between the spreading rod 610 and the material, but also has the effect of spreading the material. Avoiding direct contact also avoids the problem of damage to the material caused by the spreading rod 610, thereby ensuring the integrity of the material to the greatest extent.

[0052] See also Figure 8 and Fig. 9Slide blocks 612 are provided on the outer walls at both ends of the spreading rod 610, and limiting grooves 900 matched with the slide blocks 612 are opened on the inner walls of the first drying mechanism 300 and the second drying mechanism 400. The slide blocks 612 slide inside the limiting grooves 900 to limit the spreading rod 610, keep the surface of the spreading rod 610 in close contact with the lower surface of the material tray 800, and bulge the surface of the material tray 800. At the same time, it can also adapt to the inclined state of the first drying mechanism 300 and the second drying mechanism 400.

[0053] Embodiment 2:

[0054] See also Figure 8 The lifting mechanism 700 uses an electric push rod, which is an electric drive device that converts the rotational motion of the motor into the linear reciprocating motion of the push rod. It can be used as an execution machine in various simple or complex process flows to achieve remote control, centralized control or automatic control. The upper end of the lifting mechanism 700 is connected to the outer wall of the first drying mechanism 300 and the outer wall of the second drying mechanism 400 respectively.

[0055] See also Figure 2 , one end of the support rod 510 away from the rotating mechanism 200 is fixedly connected to the inner wall of the dryer body 100;

[0056] See also Figure 1 A first discharge groove 310 is evenly distributed on a surface of the first drying mechanism 300 close to the rotating mechanism 200, and a first travel groove 320 is evenly distributed on a surface of the first drying mechanism 300 away from the rotating mechanism 200;

[0057] See also Figure 5 The second drying mechanism 400 is provided with uniformly distributed second discharge grooves 410 and second travel grooves 420 on the surface of the side facing away from the rotating mechanism 200.

[0058] See also Figure 4 The positioning mechanism 500 also includes a positioning sleeve 520 and a groove 530. The support rod 510 is inserted into the first drying mechanism 300 and the second drying mechanism 400. The groove 530 is opened on the surface of the support rod 510, and the groove 530 is respectively embedded with the first stroke groove 320 and the second stroke groove 420.

[0059] After the first drying mechanism 300 dries the material for a period of time, the lifting mechanism 700 lifts up the edge of the first drying mechanism 300, thereby tilting the material tray 800, so that the material on the surface of the first drying mechanism 300 falls from the first discharge chute 310 to the second drying mechanism 400 below under the rotation of the spreading rod 610, and is spread out and dried again. Driven by the lifting mechanism 700, the edge of the second drying mechanism 400 drops, so that the material tray 800 inside the second drying mechanism 400 is tilted, and the material inside the second drying mechanism 400 is output from the second discharge chute 410 to the first drying mechanism 300 below. In conjunction with the rotation of the spreading rod 610, the materials inside the first drying mechanism 300 and the second drying mechanism 400 can be discharged through the first discharge chute 310 and the second discharge chute 410 respectively, and circulate in sequence, so as to realize the continuous flow of materials inside the first drying mechanism 300 and the second drying mechanism 400, and perform continuous and efficient drying.

[0060] One end of the support rod 510 facing away from the inner wall of the dryer body 100 is fixedly connected to the outer wall of the positioning sleeve 520. The positioning sleeve 520 is rotatably sleeved on the surface of the rotating mechanism 200. The positioning sleeve 520 is used to position the support rod 510 and keep the positioning mechanism 500 in relative movement with respect to the rotating mechanism 200, thereby maintaining the stability of the first drying mechanism 300 and the second drying mechanism 400.

[0061] See also Figure 2 A heat source pipe 120 is provided at the bottom end of the dryer body 100, and the bottom end of the rotating mechanism 200 is rotatably installed inside the heat source pipe 120. An input pipe 130 connected to the inside of the dryer body 100 is provided on the surface of the heat source pipe 120, and an output pipe 140 is provided on the top surface of the dryer body 100. The hot air blower inputs hot air into the heat source pipe 120, and inputs air into the input pipe 130 and the rotating mechanism 200 respectively through the heat source pipe 120. The input pipe 130 inputs hot air into the inside of the dryer body 100 to preheat the inside of the dryer body 100.

[0062] A rotary feeding mechanism 150 is provided at the top of the dryer body 100, and a check valve 160 is provided inside the rotary feeding mechanism 150; the rotary feeding mechanism 150 is driven by a motor to rotate, and the material is rotated and placed on the surface of the first drying mechanism 300, so as to achieve a preliminary uniform material spreading process. During the hot air input process, the output pipe 140 is in a closed state to prevent heat loss, and the check valve 160 in the rotary feeding mechanism 150 only keeps the material input, and the valve plate in the check valve 160 rebounds under the drive of the spring, thereby closing the valve plate to prevent hot air from overflowing from the rotary feeding mechanism 150.

[0063] A collecting hopper 110 is provided at the bottom of the dryer body 100 , and a discharge pipe 111 is connected to the surface of the collecting hopper 110 . After drying is completed, the second drying mechanism 400 is tilted to discharge the dried material into the collecting hopper 110 and discharged from the discharge pipe 111 .

[0064] Working principle: In actual application, the staff puts agricultural and sideline food raw materials into the rotating feeding mechanism 150 in turn. The rotating feeding mechanism 150 is driven by the motor to rotate and feed the materials to the surface of the first drying mechanism 300 to achieve a preliminary uniform material spreading process. The staff pre-connects the heat source pipe 120 with the hot air blower. The hot air blower inputs hot air into the heat source pipe 120, and inputs air into the input pipe 130 and the rotating mechanism 200 through the heat source pipe 120. The input pipe 130 inputs hot air into the dryer body 100 to preheat the dryer body 100. During the hot air input process, the output pipe 140 is in a closed state to prevent heat loss, and the one-way valve 160 in the rotating feeding mechanism 150 only keeps the input of the material. The valve plate in the one-way valve 160 rebounds under the drive of the spring, thereby closing the valve plate to prevent hot air from overflowing from the rotating feeding mechanism 150.

[0065] When the material is put onto the surface of the first drying mechanism 300, the driving mechanism 210 drives the rotating mechanism 200 to rotate, and the rotating mechanism 200 simultaneously drives the flipping mechanism 600 under the first drying mechanism 300 and the second drying mechanism 400, and the spreading rod 610 rotates along the lower surface of the material tray 800, and the spreading rod 610 bulges the surface of the material tray 800. With the rotation of the spreading rod 610, the material on the surface of the material tray 800 can be dispersed, which not only effectively avoids direct contact between the spreading rod 610 and the material, but also has the effect of spreading the material. Avoiding direct contact also avoids the problem of damage to the material caused by the spreading rod 610, thereby ensuring the integrity of the material to the greatest extent.

[0066] The hot air transmitted inside the rotating mechanism 200 enters the inside of the spreading rod 610 through the air pipe 620 and is ejected from the air groove 611 on the surface of the spreading rod 610. After the hot air flow is ejected from the air groove 611, the air flow passes through the material tray 800 and acts on the material on the surface of the material tray 800. The kinetic energy of the air flow can blow up the material to achieve the flipping of the material, and then cooperate with the rotation of the spreading rod 610 to evenly spread the material on the surface of the material tray 800. In addition, the hot air ejected from the air groove 611 is in close contact with the material, so that the hot air and the material are in full contact, which effectively increases the efficiency of heating and drying, thereby accelerating the drying speed.

[0067] After the first drying mechanism 300 has dried the material for a period of time, the lifting mechanism 700 lifts up the edge of the first drying mechanism 300, thereby tilting the material tray 800, so that the material on the surface of the first drying mechanism 300 falls from the first discharge chute 310 to the second drying mechanism 400 below under the rotation of the spreading rod 610, and is spread out and dried again. Driven by the lifting mechanism 700, the edge of the second drying mechanism 400 drops, so that the material tray 800 inside the second drying mechanism 400 is tilted, and the material inside the second drying mechanism 400 is output from the second discharge chute 410 to the first drying mechanism 300 below, and the cycle is repeated in sequence to achieve continuous circulation of the material in the first drying mechanism 300 and the second drying mechanism 400 for continuous and efficient drying. After the drying is completed, the second drying mechanism 400 is tilted to discharge the dried material into the collecting hopper 110 and discharged from the discharge pipe 111.

[0068] During the drying process, hot air gradually diffuses from the bottom of the dryer body 100 to the top of the dryer body 100. The mesh-designed material tray 800 will not block the flow of hot air and water vapor, which is beneficial to the circulation of hot air inside the dryer body 100 and the comprehensive discharge of water vapor. The circulation of hot air inside the dryer body 100 can effectively improve the energy utilization of hot air and help save energy consumption.

[0069] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
