Description

Technical Field

[0001] This invention belongs to the field of oatmeal processing technology, specifically relating to an oatmeal moisture control fluidization machine and method. Background Technology

[0002] Oatmeal is a common food made from oat grains. The processing of oatmeal involves initial treatments such as cleaning, hulling, and washing of the naked oats, followed by granulation, steaming, and flaking. Finally, it undergoes drying, cooling, and packaging to obtain the finished oatmeal, which is flat in shape. According to the national standard GB / T17803-1999 "Oatmeal," the moisture content of oatmeal should not exceed 14%, and the impurity content should be less than 0.5%. This standard controls the drying process, specifically using a fluidized bed dryer. Currently, fluidized bed dryers use hot air to blow into the oatmeal and vibrate it to make the oatmeal jump and move forward, resulting in significant noise. Furthermore, the vulcanizing mesh inside these fluidized bed dryers is prone to clogging, leading to uneven airflow. Summary of the Invention

[0003] The present invention aims to provide an oatmeal moisture control fluidization machine and method. The oatmeal moisture control fluidization machine and method are vibration-free and low-noise during the heating, drying and cooling of oatmeal, and the vulcanization mesh is not easily blocked. The oatmeal is thoroughly mixed and the internal temperature is uniform, resulting in a large heat exchange area on the surface of the oatmeal. The drying process achieves the optimal energy requirements and meets environmental protection standards.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An oatmeal moisture control fluidizing machine is provided, including a base and a fluidizing chamber. The fluidizing chamber is connected to a hot air device for introducing hot air into its interior and a cold air device for introducing cold air into the fluidizing chamber. The fluidizing chamber is mounted on the base by an adjustment assembly for adjusting the tilt of the fluidizing chamber.

[0006] Preferably, the fluidization chamber is provided with a fluidizing screen, and the fluidizing screen is provided with mesh groups and protrusions. The mesh group includes at least one mesh. The mesh group and the protrusions are arranged alternately, such that the mesh group has protrusions distributed in front, back, left, and right, and the protrusions have meshes distributed in front, back, left, and right.

[0007] Preferably, the mesh group and the protrusions are evenly distributed on the fluidizing mesh, and the protrusions include a front vertical surface and a rear arc surface, the arc surface gradually widening from back to front along the direction in which the oat flakes move within the fluidizing chamber.

[0008] Preferably, the fluidizing box has a hot air chamber and a cold air chamber located at the bottom of the fluidizing net. The fluidizing box has a material inlet at the top of the rear end and a material outlet at the bottom of the front end. The hot air chamber is located near the material inlet, and the cold air chamber is located near the material outlet.

[0009] Preferably, the hot air chamber is provided with an air supply channel, the cold air chamber is provided with a cold air inlet, the air supply channel is provided with a hot air rotating plate, the cold air inlet is provided with a cold air rotating plate, and the fluidizing box is provided with a driving device for driving the hot air rotating plate and the cold air rotating plate; the hot air device is connected to the air supply channel of the hot air chamber, and the cold air device is connected to the cold air inlet of the cold air chamber.

[0010] Preferably, the hot air device includes an air supply fan and a heater, with the heater disposed in the air supply channel; the cold air device includes a cold air filter box and a cold air supply fan connected in sequence, with a cold air regulating valve provided at the outlet of the cold air filter box; the top of the fluidizing box is provided with an exhaust fan, and the exhaust fan is provided with an exhaust regulating valve.

[0011] Preferably, the outlet of the air supply fan is connected to the air supply inlet of the air supply channel via a first telescopic duct, and the outlet of the cold air supply fan is connected to the cold air inlet via a second telescopic duct, so as to adaptively adjust the tilt of the fluidizing box.

[0012] Preferably, the fluidizing tank has a transparent and openable sealing plate on one side, and the fluidizing tank is equipped with a fluorescent lamp to illuminate the interior, and the material outlet is equipped with a material blocking adjustment valve.

[0013] Preferably, the tilting assembly includes a lower hinge lug disposed on the base and an upper hinge lug disposed at the bottom of the fluidizing tank. The upper hinge lug is hinged to the lower hinge lug, making one side of the fluidizing tank lighter. A tilt adjustment screw is provided between the heavier side of the fluidizing tank and the base.

[0014] This invention also provides a method for controlling the fluidization of oatmeal moisture, using the aforementioned oatmeal moisture control fluidization machine, the method comprising:

[0015] The tilt of the fluidization box is adjusted by the tilting component so that the oat flakes can flow forward along the fluidization net;

[0016] The mesh size of the fluidizing net inside the fluidizing chamber is smaller than the size of the oat flakes. The mesh groups and protrusions are evenly distributed. The mesh groups have protrusions distributed in front, behind, left, and right, and the protrusions have meshes distributed in front, behind, left, and right to prevent oat flake particles from clogging the mesh. This also ensures that the airflow on the fluidizing net is evenly distributed, making it easier to push the oat flakes into a uniform suspension state.

[0017] Start the hot air device and the cold air device so that the hot air chamber blows hot air upward from the bottom of the fluidized bed through the mesh of the fluidized bed, and the cold air chamber blows cold air upward from the bottom of the fluidized bed through the mesh of the fluidized bed, and the hot air and cold air are evenly distributed on the entire working surface of the fluidized bed.

[0018] Start the drive device that connects the hot air rotating plate in the air supply channel and the cold air rotating plate in the cold air inlet to drive the hot air rotating plate and the cold air rotating plate to rotate, so that the hot air and cold air enter the hot air chamber and the cold air chamber in the form of pulses;

[0019] The oat flakes to be dried are fed into the working area of ​​the fluidized bed through the material inlet of the fluidized bed. Driven by the upward airflow through the mesh of the fluidized bed, the oat flakes are suspended and flow forward above the fluidized bed. The oat flakes are first dehydrated by the hot air working surface above the fluidized bed, and then cooled by the cold air working surface above the fluidized bed. The flow speed of the oat flakes on the fluidized bed can be adjusted by adjusting the airflow speed of the hot and cold air devices and the inclination of the fluidized bed.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This oatmeal moisture-controlled fluidizing machine includes a base and a fluidizing chamber. The fluidizing chamber is mounted on the base via an adjustment assembly, allowing for adjustment of its tilt. Because this oatmeal moisture-controlled fluidizing machine achieves oatmeal flow by adjusting the tilt of the fluidizing chamber, it eliminates the need for a vibrator, resulting in vibration-free and low-noise operation. 2. This oatmeal moisture-controlled fluidizing machine features a fluidizing mesh with alternating mesh groups and protrusions. Each mesh group has protrusions distributed front, back, left, and right, and each protrusion has mesh groups distributed front, back, left, and right. This unique mesh structure, where the protrusions form a support structure around the mesh groups, prevents oatmeal from directly adhering to the mesh, effectively solving the problem of mesh clogging on the fluidizing mesh. 3. The fluidizing mesh is evenly distributed with mesh holes and protrusions, ensuring uniform airflow above it. This allows for thorough mixing of the oat flakes, resulting in a large surface area for heat exchange. The uniform airflow also contributes to temperature uniformity, meeting the optimal energy requirements for low-moisture drying of oat flakes, complying with environmental standards, and demonstrating energy efficiency. 4. The drive unit rotates the hot air and cold air rotating plates, causing the hot air entering the hot air chamber and the cold air entering the cold air chamber to flow in pulses. This allows the oat flakes to move in a pulsating manner on the fluidizing mesh. 5. The fluidizing chamber of this oat flake moisture control fluidizing machine has a transparent, openable sealing plate at the rear. Opening the sealing plate allows for easy cleaning of the interior, eliminating dead corners and facilitating maintenance. Attached Figure Description

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Oatmeal is a common food made from oat grains. The oatmeal processing involves initial treatments such as cleaning, hulling, and washing of the naked oats, followed by granulation, steaming, and flaking. Finally, it undergoes drying, cooling, and packaging to obtain the finished oatmeal, which is flat in shape. The oatmeal moisture control fluidized bed machine in this invention is used in the drying process to reduce the moisture content of the oatmeal to below 10%, facilitating preservation and meeting national standards for oatmeal processing.

[0032] In one embodiment, an oatmeal moisture control fluidization machine is provided, such as... Figure 1 As shown, the oatmeal moisture control fluidizing machine includes a base 1 and a fluidizing box 2. The base 1 supports the fluidizing box 2. The fluidizing box 2 is connected to a hot air device for introducing hot air into its interior and a cold air device for introducing cold air into the fluidizing box 2. The fluidizing box 2 is mounted on the base 1 by an adjustment component to adjust the tilt of the fluidizing box 2.

[0033] The oatmeal moisture control fluidizing machine is used as follows: oatmeal is fed into fluidizing tank 2, and the tilt of fluidizing tank 2 is adjusted by the tilting component so that the oatmeal can flow smoothly to the outlet of fluidizing tank 2; hot air is introduced into fluidizing tank 2 by the hot air device to heat the oatmeal in fluidizing tank 2 to remove moisture, and cold air is blown into fluidizing tank 2 to cool the oatmeal after it has been heated by the hot air device.

[0034] The oatmeal moisture control fluidization machine functions to heat and dry oatmeal and cool it down. The processed oatmeal can be quickly packaged. Since the oatmeal moisture control fluidization machine allows the oatmeal to flow by adjusting the inclination of the fluidization box, it does not use a vibrating machine and has the advantages of being vibration-free and low-noise.

[0035] Furthermore, in one embodiment, combined with Figure 2 and Figure 3 As shown, the fluidization chamber 2 of the oatmeal moisture control fluidization machine is equipped with a fluidizing screen 3. The size and shape of the fluidizing screen 3 are adapted to the internal space of the fluidizing chamber 2. Mesh groups 32 and protrusions 31 are evenly distributed on the fluidizing screen 3. Each mesh group 32 includes two meshes. In this embodiment, multiple rows of mesh groups 32 and multiple rows of protrusions 31 are evenly distributed on the fluidizing screen 3. Each row of mesh groups 32 and the corresponding protrusions 31 are staggered, so that the mesh groups 32 and the protrusions 31 are staggered. Thus, each mesh group 32 has protrusions 31 distributed in front, back, left, and right, and each protrusion 31 has mesh groups 32 distributed in front, back, left, and right.

[0036] This fluidized bed 3 with its special mesh structure, featuring raised portions 31 forming a support mechanism around the mesh group 32, prevents oat flakes from directly adhering to the mesh, effectively solving the problem of easy clogging of the mesh on the fluidized bed 3. Furthermore, in this embodiment, the fluidized bed 3 is detachably installed inside the fluidization box 2, facilitating easy removal and cleaning. Additionally, the uniformly distributed mesh group 32 and raised portions 31 on the fluidized bed 3 ensure uniform airflow above it, resulting in thorough mixing of the oat flakes. This leads to a large heat exchange area on the surface of the oat flakes, and the uniform airflow on the upper side of the fluidized bed 3 ensures uniform temperature, meeting the optimal energy requirements for low-moisture drying of oat flakes, complying with environmental standards, and being relatively energy-efficient.

[0037] Furthermore, in one embodiment, combined with Figure 2 and Figure 3 As shown, the protrusion 31 on the fluidizing net 3 inside the fluidizing chamber 2 of the oatmeal moisture control fluidizing machine is similar to the shape of a watermelon with a 90-degree angle. It includes a front vertical surface 312 and a rear arc surface 311. The arc surface 311 gradually widens from back to front along the direction in which the oatmeal moves in the fluidizing chamber 2. This shape of the arc surface 311 of the protrusion 31 facilitates the smooth forward flow of the oatmeal and does not obstruct the flow of the oatmeal.

[0038] Furthermore, in one embodiment, combined with Figure 4 As shown, the fluidization chamber 2 of the oatmeal moisture control fluidization machine has a hot air chamber 21 and a cold air chamber 22 located at the bottom of the fluidization net 3. The space above the fluidization net 3 is the fluidization chamber 25. Figure 1 As shown, a material inlet 23 is provided at the top rear end of the fluidizing box 2, and a material outlet 24 is provided at the bottom front end. The hot air chamber 21 is located on the side near the material inlet 23, and the cold air chamber 22 is located on the side near the material outlet 24.

[0039] By placing the hot air chamber 21 close to the material inlet 23, when the oat flakes enter the fluidization chamber 25 of the fluidization box 2, they are first heated by the hot air blown upwards from the hot air chamber 21 to remove moisture. As the oat flakes flow forward in the fluidization chamber 25 (arrow direction), the oat flakes are heated to reduce the moisture content to a qualified standard (adjustment required). When the oat flakes reach the front of the fluidization chamber 25, that is, the upper area of ​​the cold air chamber 22, the cold air blown upwards from the cold air chamber 22 will cool the oat flakes, so that the temperature of the oat flakes flowing out from the material outlet 24 reaches the requirements for packaging.

[0040] Furthermore, in one embodiment, combined with Figure 1 and Figure 4As shown, the oatmeal moisture control fluidizing machine has an air supply channel 26 on the rear side of the hot air chamber 21 and a cold air inlet 221 on the lower side of the cold air chamber 22. A hot air rotating plate 262 is installed in the air supply channel 26, and a cold air rotating plate 222 is installed in the cold air inlet 221. Figure 5 As shown, the hot air rotating plate 262 has a baffle along its circumference, which can block the air delivery channel 26. Similarly, the cold air rotating plate 222 in the cold air inlet 221 has the same structure, and the cold air rotating plate 222 can block the cold air inlet 221. A drive device for driving the hot air rotating plate 262 and the cold air rotating plate 222 is provided on the air delivery channel 26 of the fluidizing box 2. The drive device includes a motor 5, which drives the hot air rotating plate 262 through a belt or chain. The rotating shaft of the hot air rotating plate 262 is then driven to the cold air rotating plate 222 through a belt 51. A tensioning wheel is provided on the belt 51 for adjusting the tension of the belt 51.

[0041] The hot air device is connected to the air supply channel 26 of the hot air chamber 21, and the cold air device is connected to the cold air inlet 221 of the cold air chamber 22. Hot air is blown into the hot air chamber 21 through the hot air device, and cold air is blown into the cold air chamber 22 through the cold air device. The hot air rotating plate 262 and the cold air rotating plate 222 are driven to rotate by the drive device, so that the hot air entering the hot air chamber 21 and the cold air entering the cold air chamber 22 are in the form of pulses. This allows the oat flakes to move forward in a pulsed form on the fluidized bed 3.

[0042] Furthermore, in one embodiment, combined with Figure 1 As shown, the hot air device of the oatmeal moisture control fluidizing machine includes an air supply fan 41 and a heater 4. The heater 4 is installed in the air supply channel 26, combined with... Figure 6 As shown, the cold air device includes a cold air filter box 6 and a cold air blower 61 connected in sequence. The outlet of the cold air filter box 6 is equipped with a cold air regulating valve 62. An exhaust fan 7 is provided on the top of the fluidizing box 2, and an exhaust regulating valve 71 is provided on the exhaust fan 7.

[0043] The air blown by the air supply fan 41 is heated by the heater 4, ensuring that the air entering the hot air chamber 21 through the air supply channel 26 is hot air. The air drawn by the cold air supply fan 61 is filtered by the cold air filter box 6 to ensure the cleanliness of the blown cold air. Similarly, a filter box is also provided at the inlet of the air supply fan 41. The air supply volume of the cold air can be adjusted by the cold air adjustment valve 62, and the suction speed of the suction duct 7 at the top of the fluidized bed 2 can be adjusted by the suction adjustment valve 71. The suction duct 7 is designed to remove hot and humid gases and excess dust from inside the fluidized bed 2 during the oat flake drying process.

[0044] Furthermore, in one embodiment, combined with Figure 1As shown, the outlet of the air supply fan 41 of the oatmeal moisture control fluidizing machine is connected to the air supply inlet 261 of the air supply channel 26 via a first telescopic duct (not shown in the figure), and the outlet of the cold air supply fan 61 is connected to the cold air inlet 221 via a second telescopic duct (not shown in the figure) to adaptively adjust the tilt of the fluidizing box 2. The first and second telescopic ducts can be corrugated pipes or ducts made of soft fabric. When the fluidizing box 2 adjusts its tilt, the lengths of these two connecting areas need to adapt accordingly, hence this special design.

[0045] Furthermore, in one embodiment, combined with Figure 1 As shown, the fluidizing chamber 2 of this oatmeal moisture control fluidizing machine has a transparent and openable sealing plate (not shown in the figure) on its rear side. This sealing plate is the rear panel of the fluidizing chamber 2, which includes a support frame with an acrylic plate inside. A sealing gasket is provided between the support frame and the frame of the fluidizing chamber 2. The flow of oatmeal inside the fluidizing chamber 2 can be seen through the sealing plate. Opening the sealing plate allows for cleaning of the interior, ensuring that there are no dead corners for cleaning inside the fluidizing machine and facilitating maintenance. A fluorescent lamp 27 is provided on the fluidizing chamber 2 to illuminate the interior, making it easy to see. A baffle adjustment valve 241 is provided on the material outlet 24 to adjust the discharge speed.

[0046] Furthermore, in one embodiment, combined with Figure 1 As shown, the tilt adjustment component of the oatmeal moisture control fluidizing machine includes a lower hinge lug 8 mounted on the base 1 and an upper hinge lug 81 mounted on the bottom of the fluidizing tank 2. The upper hinge lug 81 is hinged to the lower hinge lug 8. The lower hinge lug 8 and the upper hinge lug 81 are located to the left of the center of the fluidizing tank 2, making the fluidizing tank 2 slightly lighter on the left side of the upper hinge lug 81. A tilt adjustment screw 82 is provided between the heavier side of the fluidizing tank 2 and the base. The tilt adjustment screw 82 can be a turnbuckle. The tilt adjustment screw 82 can provide support at the bottom right side of the fluidizing tank 2, so that the fluidizing tank remains stable.

[0047] The main body of this oatmeal moisture control fluidizing machine is made of stainless steel. During operation, oatmeal material is fed into the working area of ​​the fluidizing chamber 25 through the material inlet 23. Hot air and cold air are introduced into the hot air chamber 21 and cold air chamber 22 below the fluidizing net 3 through the air inlet 261 and cold air inlet 221 at the bottom of the fluidizing box 2. Then, the gas is evenly distributed on the entire working surface through the special perforated fluidizing net 3. The two rotating dampers, hot air rotating plate 262 and cold air rotating plate 222, allow the airflow to enter in a pulse form. The oatmeal is propelled forward by the fluidizing net 3. The laminar flow time of the oatmeal depends on the airflow speed of the hot and cold air upwards through the fluidizing net 3 and the inclination of the fluidizing net 3. If the airflow rate of the hot and cold air upwards through the fluidizing net 3 is larger and the airflow pulse is larger, that is, the airflow speed is larger, the laminar flow time of the oatmeal is shorter. The greater the inclination of the fluidizing net 3, the shorter the laminar flow time of the oatmeal is. The hot and humid gas and dust blown out in the fluidization chamber 2 are finally discharged through the exhaust fan 7 to achieve the purpose of heating and removing moisture from the oatmeal for drying, as well as loosening and cleaning the oatmeal.

[0048] In one embodiment, a method for controlling the moisture content of oatmeal fluidization is provided, employing the oatmeal moisture control fluidization machine described in the preceding embodiment. The method includes:

[0049] (1) Adjust the tilt of the fluidizing box 2 by adjusting the tilting component so that the oat flakes can flow forward along the fluidizing net 3.

[0050] The fluidizing mesh 3 inside the fluidizing chamber 2 of the oat moisture control fluidizing machine has mesh holes smaller than the size of the oat flakes. The mesh group 32 and the protrusions 31 are evenly distributed. The mesh group 32 has protrusions 31 distributed in all directions, and the protrusions 31 have mesh holes distributed in all directions to prevent oat flake particles from clogging the mesh holes and to make the airflow on the fluidizing mesh 3 evenly distributed, which facilitates the propulsion of the oat flakes into a uniform suspension state.

[0051] In addition, before the oat flakes are officially dried, the airflow speed of the hot and cold air upwards through the fluidized bed 3 is adjusted so that the airflow speed matches the tilt of the fluidized bed. This controls the lamination time of the oat flakes, thereby drying them to the required level, neither over-drying nor failing to meet the standards.

[0052] (2) Start the hot air device and the cold air device so that the hot air chamber 21 blows hot air upward from the bottom of the fluidized net 3 through the mesh holes on the fluidized net 3, and the cold air chamber 22 blows cold air upward from the bottom of the fluidized net 3 through the mesh holes on the fluidized net 3, and the hot air and cold air are evenly distributed on the entire working surface of the fluidized net 3.

[0053] (3) Start the drive device connected to the hot air rotating plate 262 in the air supply channel 26 and the cold air rotating plate 222 in the cold air inlet 221 to drive the hot air rotating plate 262 and the cold air rotating plate 222 to rotate, so that the hot air and cold air enter the hot air chamber 21 and the cold air chamber 22 in the form of pulses.

[0054] (4) The oat flakes to be dried are fed from the material inlet 23 of the fluidizing box 2 into the working area (fluidizing chamber 25) of the fluidizing net 3. Under the upward airflow in the mesh of the fluidizing net 3, the oat flakes are suspended and flow forward above the fluidizing net 3. The oat flakes are first removed by the hot air working surface above the fluidizing net 3, and then the temperature is reduced by the cold air working surface above the fluidizing net 3. According to the actual situation, the flow speed of the oat flakes on the fluidizing net 3 can be adjusted by adjusting the airflow speed of the hot air device and the cold air device and the inclination of the fluidizing net.
