Description

Technical Field

[0001] This utility model relates to the field of convenience food processing technology, specifically to a raw material roasting device for processing mixed grain protein bars. Background Technology

[0002] Multigrain protein bars, a convenient food made from protein raw materials and multigrain as core ingredients, combined with auxiliary ingredients and cooked together, have a texture similar to biscuits. They offer the nutritional advantages of high protein and dietary fiber, along with the convenience of being portable, making them a popular healthy snack in the market. In the processing of multigrain protein bars, pre-treatment of the multigrain is a key step. This involves roasting the oatmeal, quinoa, and other multigrain raw materials. High-temperature heating brings the multigrain to a slightly fragrant and cooked state, enhancing the flavor of the finished product and improving its digestibility and absorption, laying the foundation for subsequent mixing and molding.

[0003] Currently, the roasting of grains in industrial production mainly relies on industrial roasting pans. Most existing industrial roasting pans employ a horizontally supported jacketed structure. To facilitate rapid material discharge after roasting, the jacketed pan is typically designed to be rotatable, allowing material to be poured out by rotating the pan. However, existing roasting equipment suffers from the following technical problems in practical applications: 1. Risks of Mechanical Wear and Material Contamination: During the roasting of grains, it is necessary to avoid localized overheating that could lead to burning. Therefore, it is necessary to continuously turn the materials by hand using a roasting tool or by using mechanical equipment to drive the stirring components. This turning method inevitably involves direct mechanical contact between the roasting tool and the bottom of the roasting pot. Long-term use can easily cause mechanical wear on the pot body and stirring components. The metal fragments generated by this wear may mix into the grains, leading to the risk of material contamination and reducing the service life of the equipment. 2. High labor intensity and low efficiency: If manual stirring is used, operators need to work continuously to ensure that the materials are heated evenly, which is labor-intensive and has limited stirring efficiency, making it difficult to meet the needs of large-scale production; even if mechanical equipment is used for stirring, a complex stirring drive mechanism is required, which increases equipment cost and maintenance difficulty. 3. Significant heat loss and environmental issues: Because the material needs to be turned over during the frying process to prevent it from burning, the existing frying pans usually cannot be completely covered, resulting in a large amount of heat loss during the frying process. This not only increases energy consumption and prolongs the frying time, but also reduces energy efficiency. At the same time, the smoke and steam generated during the frying of grains cannot be collected and discharged in a concentrated manner, and are easily diffused into the production environment, causing air pollution in the workshop, which does not meet the requirements of environmentally friendly production. Utility Model Content

[0004] Therefore, in order to overcome any of the above-mentioned shortcomings, this utility model provides a raw material roasting device for processing mixed grain protein bars. This roasting device utilizes the rotation of the roasting drum to achieve self-turning of the materials inside the roasting drum, eliminating the need for manual turning and the use of other mechanical structures for turning. It also avoids mechanical wear caused by the stirring components turning the materials in the roasting pot. At the same time, combined with the rotatable feed hopper and discharge baffle, it is convenient to feed and discharge materials into the roasting drum, and it is also convenient to block the feed and discharge ports of the roasting drum during the roasting process to form an internal sealed space, reducing heat loss. Combined with the exhaust pipe, the smoke and dust can be concentrated and discharged, which also ensures the external processing environment.

[0005] This utility model is implemented as follows: a raw material roasting device for processing mixed grain protein bars includes a roasting drum, which is rotatably disposed inside the roasting chamber and keeps the inlet and outlet extending to the outside of the roasting chamber. Several heating tiles are fixed inside the frying chamber by a support plate and are located at the bottom of the frying drum; The feeding hopper is rotated and positioned above the frying drum, maintaining its connection with and separation from the inlet and outlet of the frying drum. The discharge baffle is rotatably mounted on the outer wall of the frying chamber at the outer end of the frying drum's inlet and outlet, maintaining its connection with and separation from the frying drum's inlet and outlet. The exhaust pipe is installed on the discharge baffle to facilitate the discharge of smoke and dust generated during frying.

[0006] Preferably, the frying drum is installed horizontally and rotates within the frying chamber. One end of the frying drum is open to form an inlet and outlet. Support rollers for supporting the rotation of the frying drum are provided on the outer wall of the frying chamber. The other end of the frying drum is closed, and a connecting rod is provided at the center of that end. The connecting rod extends to the outside of the frying chamber and maintains a transmission connection with the drive device and the transmission mechanism. Several circumferentially distributed spiral plates are also provided on the inner wall of the frying drum.

[0007] Preferably, a support plate is fixed above the outer wall of the frying chamber at the end where the inlet and outlet of the frying drum are located. The feed hopper is rotatably mounted on the support plate. A first connecting part and a second connecting part are respectively provided on both sides of the outer wall of the frying chamber at the end where the inlet and outlet of the frying drum are located. One end of the discharge baffle is rotatably mounted on the first connecting part, and the other end is fixedly connected to the second connecting part by a pin.

[0008] Preferably, the discharge baffle is cylindrical, and a receiving groove is provided on the corresponding end of the discharge baffle and the frying drum. When the discharge baffle is rotated to correspond with the frying drum and fixed by a pin, the end of the frying drum is in the receiving groove.

[0009] Preferably, a rotating component is provided in the receiving groove of the discharge baffle. The rotating component is coaxially arranged with the frying drum and keeps in contact with it. The exhaust pipe passes through the discharge baffle and the rotating component and is rotatably connected to the rotating component.

[0010] Preferably, a controller is also provided outside the frying chamber, and the controller is electrically connected to the heating tile and the drive device.

[0011] Preferably, a receiving hopper is also provided on the side wall of the frying chamber at the lower end of the frying drum inlet and outlet.

[0012] Compared with the prior art, the present invention has the following advantages: 1. Reduced risk of material contamination and improved product quality: This equipment achieves material self-tumbling through the rotation of the roasting drum, eliminating the need for additional manual roasting tools or mechanical stirring components. This avoids direct mechanical contact between the stirring structure and the inner wall of the drum, fundamentally reducing the risk of equipment wear and metal debris contamination, effectively solving the material contamination problem caused by mechanical wear in existing technologies. Simultaneously, the drum's rotation ensures uniform heating of the grains, preventing localized overheating and burning, and maintaining a uniformly roasted and slightly fragrant state.

[0013] 2. Reduced labor intensity and maintenance costs: Compared with the existing technology of manual stirring or complex stirring mechanism driven turning, this equipment relies on the rotation of the drum to turn the material, which does not require continuous operation by operators and significantly reduces the labor intensity of manual labor; at the same time, it eliminates the need for an additional stirring drive mechanism, simplifies the overall structure of the equipment, and reduces the manufacturing cost and later maintenance difficulty.

[0014] 3. Energy saving and consumption reduction, shortening the roasting cycle: The rotatable feed hopper and discharge baffle allow for easy discharge by opening the discharge baffle during feeding and feeding by rotating the feed hopper to the inlet / outlet position. During roasting, the discharge baffle is rotated to the inlet / outlet position, creating a sealed roasting space within the roasting drum. This effectively reduces heat loss during roasting, solving the problem of severe heat loss in existing open-type roasting pans. The sealed structure not only reduces energy consumption but also allows the temperature inside the drum to rise rapidly and remain stable, shortening the time required for grain ripening, improving energy efficiency, and reducing production energy costs.

[0015] 4. Environmentally friendly and pollution-free, improving the production environment: The exhaust pipes of the equipment can collect and discharge the smoke and steam generated during the frying process, avoiding the spread of smoke and dust to the production workshop and causing air pollution. At the same time, the enclosed frying space reduces the impact of heat leakage on the workshop temperature, creating a more comfortable and cleaner production environment for operators, which meets the industry requirements for environmentally friendly production.

[0019] As described in the background section, existing industrial woks require manual stirring of materials inside to prevent them from burning. This stirring is often done manually using stirring tools or machinery, which causes mechanical wear between the wok and the machinery, potentially resulting in mechanical debris falling into the material. Furthermore, manual stirring is laborious, and because the material needs to be stirred, the wok cannot be closed, leading to excessive heat loss, wasted energy, and direct emission of fumes into the external environment, impacting the processing environment.

[0020] For the reasons stated above, please refer to the appendix for solutions to these problems. Figure 1 ~Appendix Figure 7 This utility model provides a raw material roasting device for processing mixed grain protein bars, including a roasting drum 10, which is rotatably disposed inside the roasting chamber 1 and keeps the inlet and outlet extending to the outside of the roasting chamber 1. Several heating tiles 13 are fixed inside the frying chamber 1 by a support plate 12 and are located at the bottom of the frying drum 10; The feeding hopper 2 rotates and is positioned above the frying drum 10. The outer wall of the frying chamber 1 remains connected to and separates from the inlet and outlet of the frying drum 10. The discharge baffle 3 is rotatably mounted on the outer wall of the frying chamber 1 at the outer end of the inlet and outlet of the frying drum 10, maintaining its connection with and separation from the inlet and outlet of the frying drum 10.

Several circumferentially distributed spiral plates are also provided on the inner wall of the frying drum 10.

[0023] As mentioned above, the spiral plate is designed to ensure that the roasting drum can convey materials during rotation, facilitating subsequent automatic discharge and further enabling material tumbling.

[0025] Furthermore, the first connecting part can be a hinge or a latch, and the second connecting part can be a slot preset on the insert block. It can be fixed by inserting the pin that is slidably set on the discharge baffle into the slot on the insert block on the outer wall of the frying chamber.

Under the action of the spiral plate, the internal material is discharged, thus completing the frying process.

[0035] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model.
