Description

Technical Field

[0001] This utility model relates to the field of oat food raw material drying technology, and in particular to a dryer for oat food raw materials. Background Technology

[0002] In the food processing industry, oats are a common and healthy food ingredient, and their drying process is crucial. Traditional methods for drying oat ingredients primarily involve placing the raw materials in a mixing tank and relying on the combined action of a mixing mechanism and a hot air blower. However, this traditional method has significant drawbacks. Because oat ingredients are often clump-like during initial mixing, these clumps are difficult to disperse quickly during mixing, leading to a substantial increase in mixing time. This extended mixing time not only reduces drying efficiency but can also affect the quality of the oat ingredients due to uneven drying in certain areas. It may even result in some ingredients being over-dried while others remain under-dried. Therefore, we propose a dryer for oat food ingredients to address these problems. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a dryer for oat food ingredients.

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

[0005] A dryer for oat food ingredients includes a support frame, a drying tank mounted on the upper end of the support frame, multiple nozzles evenly spaced on one side of the drying tank, a stirring mechanism mounted on one side of the drying tank, two discharge pipes connected to the upper ends of the drying tank, a separation box connected to the upper end of the two discharge pipes, a feed hopper connected to the upper end of the separation box, a protective box fixed to the lower end of the separation box, a rotary joint rotatably fitted inside the protective box, a fixed pipe fixed to the fixed end of the rotary joint, a spray bar fixed to the rotating end of the rotary joint, a rotating device connected to the spray bar, the upper end of the spray bar penetrating the side wall of the separation box and extending into the separation box, a conical separation hood connected to the upper end of the spray bar, multiple spray holes evenly spaced around the perimeter of the conical separation hood, a hot air conveying mechanism mounted on one side of the upper end of the support frame, one end of the hot air conveying mechanism connected to the multiple nozzles and the fixed pipe.

[0006] Preferably, the stirring mechanism includes a first drive motor fixed to one side of the middle of the drying tank, a stirring rod connected to the end of the output shaft of the first drive motor, and multiple stirring blades connected at equal intervals around the stirring rod.

[0007] Preferably, the rotating device includes a second drive motor fixed inside the protective box on one side, and gear sets are fixed on the output shaft and the spray bar of the second drive motor, and the two gear sets mesh with each other.

[0008] Preferably, the hot air conveying mechanism includes a hot air fan fixed to one side of the upper end of the support frame, the air outlet of the hot air fan is connected to a gas delivery pipe, one end of the gas delivery pipe is connected to one side of the fixed pipe, and one side of the gas delivery pipe is connected to multiple nozzles.

[0010] Preferably, multiple sensors are installed on the circumferential sidewall inside the drying tank.

[0011] In this invention, when drying is required:

[0012] 1. Raw material feeding and preliminary separation and drying: The operator feeds the oat raw material to be dried into the equipment through the feeding hopper. The raw material enters the separation box through the connecting pipe. At this time, the second drive motor starts and drives the spray bar to rotate through the gear set, which in turn makes the conical separation hood rotate. At the same time, the hot air generated by the hot air blower reaches the spray bar through the air supply pipe, fixed pipe and rotary joint, and finally sprays out from the spray hole on the conical separation hood. The rotating conical separation hood and the sprayed hot air pre-separate and disperse the sticky raw materials, and at the same time achieve preliminary drying.

[0013] 2. Raw material conveying: The raw materials, after preliminary separation and drying, enter the drying tank through the discharge pipe;

[0014] 3. Further drying: The first drive motor starts, driving the stirring rod and stirring blades to rotate, stirring the raw materials in the drying tank. The hot air generated by the hot air blower is delivered to each nozzle through the air supply pipe and sprayed in from one side of the drying tank. Combined with the stirring action, the raw materials are in full contact with the hot air during the continuous turning process, further improving the speed and comprehensiveness of drying.

[0015] 4. Discharge: When the sensor in the drying tank detects that the raw material has reached the drying requirements, the electric valve on the discharge pipe is opened to discharge the dried raw material.

[0016] This utility model has the following advantages:

[0017] 1. By setting a conical separation hood in the separation box to pre-separate and disperse the raw materials, the problem of raw material adhesion is effectively solved, the subsequent stirring time is reduced, and the drying efficiency is greatly improved;

[0018] 2. The combined action of the stirring mechanism and the nozzles ensures that the raw materials can come into uniform contact with the hot air in the drying tank, avoiding uneven drying in certain areas and guaranteeing the drying quality of the oat raw materials.

Combined with the electric valves on the discharge pipe and connecting pipe, the drying and discharge process is automated, reducing manual intervention and improving the stability and reliability of production.

[0020] In summary, this invention not only effectively solves the problem of raw material adhesion and reduces subsequent stirring time, greatly improving drying efficiency, but also ensures that the raw materials can be evenly contacted with hot air in the drying tank, avoiding uneven drying in certain areas, guaranteeing the drying quality of oat raw materials, reducing manual intervention, and improving the stability and reliability of production.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-4 A dryer for oat food ingredients includes a support frame 9, which is made of high-strength stainless steel and has good corrosion resistance and stability.

[0028] A drying tank 5 is installed on the upper end of the support frame 9. Multiple nozzles 20 are installed at equal intervals on one side of the drying tank 5. The nozzles 20 are distributed at an inclined angle and at equal intervals on one side of the drying tank 5, which can make the hot air evenly spray into the drying tank 5 and avoid the formation of drying dead corners.

[0029] A stirring mechanism is installed on one side of the drying tank 5. Both sides of the upper end of the drying tank 5 are connected to a discharge pipe 4. The upper ends of the two discharge pipes 4 are connected to a separation box 2. The upper end of the separation box 2 is connected to a feed hopper 1. The feed hopper 1 is funnel-shaped. The funnel-shaped feed hopper 1 makes it convenient for operators to put oat raw materials in and can guide the raw materials smoothly into the separation box 2, which facilitates the feeding of raw materials.

[0030] A protective box 3 is fixed to the lower end of the separation box 2. A rotary joint 15 is rotatably sleeved inside the protective box 3. A fixed pipe 21 is fixed to the fixed end of the rotary joint 15. A spray bar 14 is fixed to the rotating end of the rotary joint 15. A rotating device is connected to the spray bar 14. The upper end of the spray bar 14 penetrates the side wall of the separation box 2 and extends into the separation box 2. A conical separation hood 12 is connected to the upper end of the spray bar 14. The centrifugal force field formed by the rotating conical separation hood 12 can effectively break the adhesion between the raw materials, disperse the raw materials into smaller particles, and increase the contact area between the raw materials and the hot air.

[0031] The cone-shaped separation hood 12 is provided with multiple spray holes 13 at equal intervals around its circumference. A hot air conveying mechanism is provided on one side of the upper end of the support frame 9. One end of the hot air conveying mechanism is connected to multiple nozzles 20 and a fixed pipe 21. The synergistic effect of the stirring mechanism and the nozzles 20 enables the raw materials to come into uniform contact with the hot air in the drying tank 5, avoiding the problem of uneven drying in some areas and ensuring the drying quality of the oat raw materials.

[0032] The stirring mechanism includes a first drive motor 10 fixed on one side of the middle part of the drying tank 5. The output shaft of the first drive motor 10 is connected to a stirring rod 18. Multiple stirring blades 19 are connected at equal intervals around the stirring rod 18. The first drive motor 10 has high power and stable speed, which can provide sufficient power to the stirring rod 18 to ensure efficient stirring.

[0033] The rotating device includes a second drive motor 16 fixed inside the protective box 3. Gear sets are fixed on the output shaft of the second drive motor 16 and the spray bar 14, and the two gear sets mesh with each other. The gear sets use high-precision gears, which can accurately transmit power and enable the spray bar 14 to rotate stably, ensuring the uniformity of the rotation of the conical separation cover 12.

[0034] The hot air conveying mechanism includes a hot air blower 7 fixed on one side of the upper end of the support frame 9. The outlet end of the hot air blower 7 is connected to a gas delivery pipe 6. One end of the gas delivery pipe 6 is connected to one side of the fixed pipe 21. One side of the gas delivery pipe 6 is connected to multiple nozzles 20, which can quickly generate high-temperature hot air. The temperature and flow rate of the hot air can be adjusted as needed to meet the requirements of different drying stages. The SED-20kW hot air blower can quickly generate a large amount of hot air, ensuring that sufficient heat is provided to the drying tank in a short time, so that the raw materials can reach the drying requirements quickly.

[0035] The upper end of the separation box 2 is connected to the connecting pipe 11, and the upper end of the connecting pipe 11 is connected to the lower end of the feed hopper 1. The lower end of the drying tank 5 is connected to the discharge pipe 8. Both the discharge pipe 8 and the connecting pipe 11 are equipped with electric valves. The electric valves adopt an intelligent control system, which can automatically open and close according to the operating status of the equipment and preset parameters, thereby improving the automation level of the equipment.

[0036] Multiple sensors are installed on the circumferential side wall inside the drying tank 5. These sensors are highly accurate and sensitive, enabling them to accurately detect the degree of dryness of the raw materials and provide reliable data support for the operation of the equipment.

[0037] In this invention, when drying is required:

[0038] 1. Raw material feeding and preliminary separation and drying: The operator feeds the oat raw material to be dried into the equipment through the feed hopper 1. The raw material enters the separation box 2 through the connecting pipe 11. At this time, the second drive motor 16 starts and drives the spray bar 14 to rotate through the gear set, which in turn causes the conical separation hood 12 to rotate. At the same time, the hot air generated by the hot air blower 7 reaches the spray bar 14 through the air supply pipe 6, the fixed pipe 21 and the rotary joint 15, and finally sprays out from the spray hole 13 on the conical separation hood 12. The rotating conical separation hood 12 and the sprayed hot air pre-separate and disperse the sticky raw materials, and at the same time achieve preliminary drying.

[0039] 2. Raw material conveying: The raw materials, after preliminary separation and drying, enter the drying tank 5 through the discharge pipe 4;

[0040] 3. Further drying: The first drive motor 10 starts, driving the stirring rod 18 and stirring blade 19 to rotate, stirring the raw materials in the drying tank 5. The hot air generated by the hot air blower 7 is delivered to each nozzle 20 through the air supply pipe 6 and sprayed in from one side of the drying tank 5. Combined with the stirring action, the raw materials are in full contact with the hot air during the continuous turning process, further improving the speed and comprehensiveness of drying.

[0041] 4. Discharge: When the sensor in the drying tank 5 detects that the raw material has reached the drying requirements, the electric valve on the discharge pipe 8 is opened to discharge the dried raw material.

[0042] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
