Description

Technical Field

[0001] The present invention relates to the technical field of wheat conditioning equipment, and particularly to a wheat water addition device. Background Art

[0002] Before entering the flour milling process, wheat must undergo pretreatment steps such as cleaning, water addition, and wheat conditioning. Among them, the main purpose of the water addition link is to adjust the moisture content of wheat grains, which is beneficial to the subsequent separation of endosperm and bran, and to improve the flour yield and flour quality. Whether the water addition is uniform directly affects the wheat conditioning effect and the flour milling quality.

[0003] At present, the water addition equipment widely used in small and medium-sized flour mills is a spiral water addition machine. This equipment realizes the mixing of water and wheat grains by means of spiral conveying of wheat grains and synchronously spraying water mist at the feeding port position. Due to the single layout position, it is difficult for the water mist to contact the wheat grains evenly, resulting in insufficient water absorption or excessive water absorption of some wheat grains. Summary of the Invention

[0004] The purpose of the present invention is to improve the uniformity of water addition, and a wheat water addition device is proposed.

[0005] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0006] A wheat water addition device includes an outer housing. An inner cylinder is installed at intervals inside the outer housing. A spiral device is installed on the outer housing, and the spiral device can make the material tumble and move inside the inner cylinder. Water mist passing holes are provided on the circumferential side of the inner cylinder. There is an annular space inside the outer housing that wraps the outer circumferential side of the inner cylinder. The water addition device further includes a water mist nozzle for conveying water mist to the annular space, a feeding cylinder for feeding material into the inner cylinder, and a discharging cylinder for discharging material.

[0007] The inner cylinder is a cylindrical cylinder with both ends open. The water addition device includes a first cylinder and a second cylinder. One end of the first cylinder is fixedly and sealed with one end of the outer housing. The other end of the first cylinder is connected and assembled with one end of the inner cylinder. One end of the second cylinder is fixedly and sealed with the other end of the outer housing. The other end of the second cylinder is connected and assembled with the other end of the inner cylinder. The feeding cylinder is fixedly and connected with the second cylinder. The discharging cylinder is fixedly and connected with the first cylinder.

[0008] The first cylinder, the second cylinder, and the inner cylinder are coaxially arranged. The first cylinder and the second cylinder are both rotationally connected to the inner cylinder. A damping adjustment component is provided between the inner cylinder and the outer housing.

[0009] There are at least two water mist nozzles. The multiple water mist nozzles are arranged at intervals along the axis direction of the inner cylinder. The water mist nozzles are fixedly assembled with the outer housing.

[0010] The damping adjustment assembly includes a stud and a damping head. The stud is threadedly connected to the outer housing, the damping head is rotatably connected to the stud, and the damping head is in frictional engagement with the outer wall of the inner cylinder.

[0011] The outer peripheral wall of the end of the second cylinder is inserted into the inner wall of the inner cylinder and the two are rotatably connected. The inner peripheral wall of the end of the first cylinder is sleeved on the outer peripheral wall of the inner cylinder and the two are rotatably connected.

[0012] Brush hairs are installed on the outer wall of the inner cylinder along its length direction, and the brush hairs are in contact with the inner peripheral wall of the outer housing.

[0013] The outer housing is inclined. The feed cylinder is located at the higher end of the outer housing, the discharge cylinder is located at the lower end of the outer housing. A waste outlet is opened at the lower part of the lower end of the outer housing, and a waste bin is installed outside the outer housing at the waste outlet.

[0014] The spiral device includes paddle blades, a motor, and a support shaft. The motor is fixed to the outer housing. The support shaft is rotatably connected to the outer housing, and the motor is in transmission connection with the support shaft. Paddle blades distributed in a spiral manner are installed on the part of the support shaft located inside the inner cylinder.

[0015] A wheat water addition device proposed by the present invention has the beneficial effects that the water mist of this device enters evenly through the four sides of the inner cylinder, replacing the "single-point spraying" method in traditional equipment, making the wheat grains receive water more comprehensively, significantly reducing the phenomenon of local over-wetting or over-drying. Under the agitation of the spiral mechanism, the wheat grains keep tumbling, and the water mist can more fully contact and adhere to the surface of the wheat grains, enhancing the water penetration effect. Description of the Drawings

[0016] Figure 1 It is a schematic structural diagram of an embodiment of the present invention.

[0017] In the figure: feed cylinder 1, water mist nozzle 2, inner cylinder 3, stud 4, damping head 5, first cylinder 6, paddle blade 7, motor 8, support shaft 9, discharge cylinder 10, waste outlet 11, waste bin 12, brush hair 13, outer housing 14, second cylinder 15, annular space 16. Detailed Embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Refer to Figure 1, A wheat water addition device, comprising an outer housing 14, an inner cylinder 3 is installed at intervals inside the outer housing 14, a spiral device is installed on the outer housing 14, and the spiral device can make the material tumble and move inside the inner cylinder 3. Water mist through holes are provided on the peripheral side of the inner cylinder 3. There is an annular space 16 inside the outer housing 14 that wraps around the outer peripheral side of the inner cylinder 3. The water addition device further includes a water mist nozzle 2 for delivering water mist to the annular space 16, a feed cylinder 1 for delivering material to the inner cylinder 3, and a discharge cylinder 10 for discharging material.

[0020] When the device is running, the wheat raw material enters the inner cylinder through the feed cylinder and is driven by the spiral stirring mechanism, and continuously tumbles and advances under the drive of the spiral shaft. During this process, the water mist nozzle injects high-pressure water mist into the annular space, so that the fine water mist is evenly distributed in the annular space and penetrates into the inner part of the inner cylinder through multiple penetration holes on the inner cylinder, thereby achieving the effect that the material is wrapped with fine mist from all around at multiple angles during the conveying and tumbling processes for water addition.

[0021] The water mist of this device enters evenly through the periphery of the inner cylinder, replacing the "single-point spraying" method in traditional equipment, making the wheat grains receive water more comprehensively, significantly reducing the phenomenon of local over-wetting or over-drying. Under the agitation of the spiral mechanism, the wheat grains keep tumbling, and the water mist can more fully contact and adhere to the surface of the wheat grains, enhancing the water penetration effect.

[0022] The inner cylinder 3 is a cylindrical cylinder with both ends open. The water addition device includes a first cylinder 6 and a second cylinder 15. One end of the first cylinder 6 is fixedly and sealed with one end of the outer housing 14, and the other end of the first cylinder 6 is connected and assembled with one end of the inner cylinder 3. One end of the second cylinder 15 is fixedly and sealed with the other end of the outer housing 14, and the other end of the second cylinder 15 is connected and assembled with the other end of the inner cylinder 3. The feed cylinder 1 is fixedly and connected with the second cylinder 15, and the discharge cylinder 10 is fixedly and connected with the first cylinder 6.

[0023] During the installation process of this structure, the inner cylinder is positioned, fixed and sealed inside the outer housing through the first cylinder and the second cylinder. Since both ends of the inner cylinder are connected by a cylindrical socket connection, the inner cylinder can evenly divide the annular space between the inner cylinder and the outer housing, forming an ideal surrounding spray cavity. At the same time, the feeding and discharging are introduced and exported through the second cylinder and the first cylinder at both ends, ensuring the continuous flow and sealed transportation of the material. The inner cylinder is fixed by the cylindrical structures at both ends, without additional brackets or connecting rods. The overall design is simple and clear. Through the double-end fixation of the first cylinder and the second cylinder, it avoids offset caused by vibration or the drive of the spiral mechanism during operation. The suspended installation structure naturally forms a closed annular space between the inner cylinder and the outer housing, which is conducive to realizing the surrounding water mist supply. The sealed structures at both ends can prevent the water mist from escaping, improve the spray efficiency, and ensure the cleanliness of the working environment.

[0024] The first cylinder 6, the second cylinder 15, and the inner cylinder 3 are coaxially arranged. The first cylinder 6 and the second cylinder 15 are both rotationally connected to the inner cylinder 3. A damping adjustment component is provided between the inner cylinder 3 and the outer housing 14.

[0025] During the watering process, as the material enters the inner cylinder from the feed cylinder, the spiral device exerts a propulsive force on the material and produces a tumbling and stirring effect. Due to the friction between the material and the inner cylinder wall, the inner cylinder will be driven to rotate as the material continues to roll forward. This rotation is controlled by the speed limit and damping of the damping adjustment component to prevent the inner cylinder from spinning too fast or reacting slowly.

[0026] This structure causes the inner drum to rotate slowly while the material is moving, achieving a double disturbance effect: on the one hand, the material itself is pushed and tumbled by the spiral, and on the other hand, the overall rotation of the inner drum further enhances the disturbance mixing between the materials and between the materials and the water mist.

[0027] The follow-up rotation of the inner drum in this solution increases the movement complexity of the material, increases the rolling frequency, and helps the moisture conduction between the grains. The multi-angle disturbance makes it easier for the water mist to adhere to the surface of the grains evenly, reduces dead angles, and improves the consistency of water application. The rotation speed of the inner drum is controlled by the damping adjustment component to adapt to different moisture requirements or material flow rates.

[0028] There are at least two water mist nozzles 2 , and the plurality of water mist nozzles 2 are arranged at intervals along the axial direction of the inner tube 3 . The water mist nozzles 2 are fixedly assembled with the outer shell 14 .

[0029] Multiple water mist nozzles are distributed along the axis, so that the spray is no longer concentrated in a fixed area, but achieves uniform coverage along the length of the inner tube. The sprayed water mist hits the outer wall of the inner tube, and the water mist will further diffuse in the annular space and penetrate into the inner tube through multiple penetration holes distributed on the inner tube.

[0030] At the same time, since the inner cylinder is in a rotating state during operation, the water mist spray is not only used to wet the material, but also to continuously and dynamically clean the outer wall of the inner cylinder. The mist water flow has a good flushing effect on the penetration hole, which can effectively reduce the problems of scaling and blockage at the hole, and improve the long-term operation stability and maintenance convenience of the device.

[0031] This solution can achieve wider spray coverage of the outer wall of the inner cylinder and the internal materials, improve the overall water consistency, and rotate the inner cylinder with continuous spraying to have a water mist cleaning effect, prevent dust accumulation or clogging, and extend the service life. The water mist directly impacts the pores and has self-dredging ability, reducing the frequency of manual cleaning. The self-cleaning function of the equipment reduces the risks of mildew and bacterial colony growth, and is more in line with food processing hygiene requirements.

[0032] The damping adjustment assembly includes a stud 4 and a damping head 5. The stud 4 is threadedly connected to the outer housing 14, the damping head 5 is rotatably connected to the stud 4, and the damping head 5 is in frictional engagement with the outer wall of the inner cylinder 3. By rotating the stud 4, the pressure between the damping head 5 and the outer wall of the inner cylinder 3 is changed. Different pressures will generate different frictional forces, and different frictional forces will generate different damping effects. The structure is simple.

[0033] The spiral device includes a blade 7, a motor 8, and a support shaft 9. The motor 8 is fixed to the outer housing 14, the support shaft 9 is rotatably connected to the outer housing 14, and the motor 8 is drivingly connected to the support shaft 9. The part of the support shaft 9 located inside the inner cylinder 3 is provided with blades 7 arranged in a spiral. The outer housing 14 is inclined. The feed cylinder 1 is located at the higher end of the outer housing 14, the discharge cylinder 10 is located at the lower end of the outer housing 14. A waste outlet 11 is opened at the lower part of the lower end of the outer housing 14. A waste bin 12 is installed outside the outer housing 14 at the waste outlet 11. The outer peripheral wall of the end of the second cylinder 15 is inserted into the inner wall of the inner cylinder 3 and the two are rotatably connected. The inner peripheral wall of the end of the first cylinder 6 is sleeved on the outer peripheral wall of the inner cylinder 3 and the two are rotatably connected.

[0034] In terms of the rotary connection structure, the outer peripheral wall of the end of the second cylinder is inserted into the inner wall of the inner cylinder to form a rotatable connection; while the inner peripheral wall of the end of the first cylinder is sleeved on the outer peripheral wall of the inner cylinder, also forming a rotatable connection. The above structure, combined with the inclined arrangement of the outer housing, enables the material to move smoothly under the combined action of gravity and spiral propulsion.

[0035] The inclined structure utilizes gravity assistance to make it easier for the material to naturally move downward along the moving direction of the inner cylinder, reducing jamming phenomena. The connecting part adopts an inserted and sleeved rotary fit, and the stepped structure effectively prevents material particles from entering the bearing or the rotating connection, reducing the risks of jamming and wear. The waste bin 12 receives the waste residue discharged from the outer wall of the inner cylinder during spraying and washing.

[0036] Brush hairs 13 are installed along the length direction of the outer wall of the inner cylinder 3, and the brush hairs 13 are in contact with the inner peripheral wall of the outer housing 14. Since the inner cylinder can rotate during operation, the brush hairs rotate with the inner cylinder, forming a continuous mechanical cleaning effect on the inner wall of the outer housing. Since the water mist nozzles are arranged at intervals along the axial direction, the water mist coverage is wide. Each time the brush hairs rotate with the inner cylinder to the spraying area, they will be sprayed and washed by the water mist once, taking away the dust and impurities adhered to the brush hairs and realizing self-cleaning of the brush hairs.

[0037] Through the internal and external double-cylinder structure, spiral tumbling, surrounding water mist, rotary brushing and multi-stage self-cleaning design, this device achieves efficient and uniform water addition to materials during movement, significantly improving the quality and efficiency of wheat pretreatment. The device not only has excellent water addition uniformity, but also improves the stable operation ability, automatic cleaning ability and maintenance convenience of the equipment through multiple optimization measures such as inclined arrangement, rotating self-cleaning bristles and water mist dredging. It is suitable for continuous and large-scale processing environments and has good industrial application prospects.

[0038] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technical solution, concept and design obtained by those skilled in the art in the technical scope disclosed by the present invention through equivalent replacement or change based on the technical solution and inventive concept of the present invention shall be covered by the protection scope of the present invention.
