Description

Technical Field

[0001] This utility model relates to the technical field of peanut processing equipment, specifically a peanut pre-processing and roasting equipment. Background Technology

[0002] In recent years, with the rapid growth in consumption of snack foods and nuts, the peanut processing industry has increasingly higher requirements for product quality and flavor. Pre-processing roasting, a key step in peanut processing, ensures that peanuts achieve a golden color and rich aroma through uniform heating and appropriate turning, providing ideal physical conditions for subsequent seasoning, packaging, and storage. Unlike traditional roasting, pre-processing roasting does not require extremely high temperatures; it simply pre-treats the peanuts to facilitate better subsequent processing. However, most peanut roasting equipment on the market today is traditional drum roasting or intermittent hot air roasting, typically designed only for final roasting or simple heating, lacking specific design for the pre-processing stage.

[0003] Existing equipment is difficult to adapt to the preheating environment, and the baking temperature is too high, which affects the pre-processing baking effect. In addition, some equipment is prone to accumulation or uneven heating during the baking process, and the turning efficiency is low, which affects the pre-processing effect. It is difficult to achieve continuous or efficient production and cannot meet the requirements of high-quality industrial pre-processing baking.

[0004] Therefore, existing technologies need further improvement and enhancement. Utility Model Content

[0005] The purpose of this invention is to provide a peanut pre-processing and roasting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a peanut pre-processing and roasting equipment, comprising a feeding section, a screening section, a roasting section, and a receiving section, wherein the feeding section is connected to the screening section, and a feeding channel is provided between the roasting section and the screening section; rotating tables are provided on both sides of the roasting section, so that the roasting section has a roasting state and a feeding state, and the receiving section is provided relative to the end of the feeding channel.

[0007] In a preferred embodiment of this application, the screening section includes a movable screen and a vibrating element. The movable screen is rotatably disposed on the inner wall of the baking equipment, and the vibrating element is disposed inside the movable screen.

[0008] In a preferred embodiment of this application, the screening section housing has a feeding port, which is connected to the feeding channel, and the feeding port is equipped with an opening and closing door.

[0009] In a preferred embodiment of this application, the feeding channel is an arc-shaped channel structure, with a discharge port at the end of the feeding channel and connected to the baking section.

[0010] In a preferred embodiment of this application, the baking section includes a baking drum and a hot air assembly. The outer wall of the baking drum is rotatably connected to the rotating table to achieve up-and-down swinging. The hot air assembly is disposed inside the baking drum.

[0011] In a preferred embodiment of this application, the baking drum includes a storage cylinder, a positioning cylinder, and a drive assembly disposed between the two. The positioning cylinder has double doors on both sides, and the feeding channel is telescopically configured to allow space for opening and closing the doors.

[0012] In a preferred embodiment of this application, the drive assembly includes a power component, an output wheel, a transmission wheel, and a transmission belt. The transmission wheel is sleeved on the outer wall of the storage cylinder, and the transmission belt connects the output wheel and the transmission wheel.

[0013] In a preferred embodiment of this application, the hot air assembly includes a blowing hot air duct and a radiant hot air duct, the radiant hot air duct being arranged around the inner wall of the positioning cylinder, and the air outlet of the blowing hot air duct facing the inlet of the storage cylinder.

[0014] In a preferred embodiment of this application, the hot air blower is disposed on the outer wall of the positioning cylinder, and the blowing hot air pipe and the radiant hot air pipe are arranged in the same line.

[0015] In a preferred embodiment of this application, the receiving part is located below the baking part and is provided with a funnel-shaped structure.

[0016] This utility model has the following beneficial effects: 1. This application proposes a peanut pre-processing and roasting equipment, which, by setting up a feeding section, a screening section, a roasting section, and a receiving section, enables continuous pre-processing and roasting of peanuts. The feeding section is connected to the screening section, and together with a movable screen and vibrating components, it grades, cleans, and initially screens the peanuts, ensuring uniformity of the peanuts during subsequent roasting and reducing impurities carried by the peanuts. The feeding channel is connected to the roasting section, and the arc-shaped channel design ensures smooth conveying, guaranteeing that the peanuts enter the roasting chamber smoothly. The roasting section can preheat and roast the peanuts to enhance their aroma, facilitating subsequent processing of various peanuts. The receiving section is located below the roasting section, and together with a funnel-shaped structure, it enables efficient collection and continuous conveying of roasted peanuts, thereby significantly improving production efficiency and ensuring the consistency of pre-processing and roasting.

[0017] 2. As a preferred embodiment of this application, by combining a movable screen and internal vibrating components within the screening section, and by installing an opening and closing door at the feeding port, the equipment can achieve efficient peanut screening, clean and uniform feeding, while reducing the accumulation and blockage of peanuts during the conveying process. The arc-shaped feeding channel design not only ensures smooth flow of peanuts during conveying but also creates conditions for effective tumbling of the drum roasting section, allowing the peanuts to reach an ideal material distribution state before entering the roasting chamber, thereby improving roasting uniformity and the consistency of the final product's color and taste.

[0018] 3. As a preferred embodiment of this application, through the synergistic action of the double-cylinder structure (storage cylinder and positioning cylinder) of the baking section, the drive assembly, and the hot air assembly, the equipment achieves continuous tumbling and uniform heating of peanuts during the pre-processing baking process. The baking drum can swing up and down on the rotating platform, facilitating the loading of peanuts and their discharge after pre-baking. The hot air assembly includes blowing hot air pipes and surrounding radiant hot air pipes, which can heat the peanuts from different directions, improving heat transfer efficiency and ensuring timely removal of moisture. The positioning cylinder's double-door design cooperates with the drum, facilitating easy loading and unloading, while also providing a certain degree of sealing to prevent peanuts from flying out of the positioning cylinder. This improves the efficiency, uniformity, and safety of peanut pre-processing baking, while also considering ease of operation and maintenance. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0025] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Please see Figure 1-5 The present invention provides an embodiment of a peanut pre-processing and roasting device, comprising a feeding section 1, a screening section 2, a roasting section 3, and a receiving section 4. The feeding section 1 is connected to the screening section 2, and a feeding channel 5 is provided between the roasting section 3 and the screening section 2. Rotating tables 6 are provided on both sides of the roasting section 3, so that the roasting section 3 has a roasting state and a feeding state. The receiving section 4 is provided at the end of the feeding channel 5.

[0027] As shown in the figure, each component is equipped with a shell structure to protect the internal structure and facilitate the conveying of peanuts. As for the feeding part 1, it can be seen from the figure that the feeding part 1 adopts a funnel-shaped structure, which makes it convenient for peanuts to be fed from top to bottom by weight and the inclined slope.

[0028] Furthermore, such as Figure 2 As shown, the screening section 2 includes a movable screen 21 and a vibrating element 22. The movable screen 21 is rotatably mounted on the inner wall of the baking equipment, and the vibrating element 22 is placed inside the movable screen 21. The movable screen 21 can be provided with a frame structure to surround the screen structure. As for the vibrating element 22, multiple vibrating elements can be provided and evenly distributed inside the frame structure to facilitate vibration of the movable screen 21 and prevent peanuts from accumulating.

[0029] In addition, when in use, peanuts fall on the surface of the movable screen 21, and impurities such as gravel and residue can fall off under the shaking of the movable screen 21. Furthermore, by setting an external motor to rotately connect with the movable screen 21, the movable screen 21 is driven to swing at a certain angle. After the impurities are screened, the movable screen 21 is tilted, so that the peanuts on the surface can flow along the tilted screen to the feeding channel 5.

[0030] Optionally, the housing of the screening section 2 has a feeding port 7, which is connected to the feeding channel 5, and the feeding port 7 is equipped with an opening and closing door 8, such as... Figure 1 and Figure 3 As shown, the feeding port 7 itself can be equipped with an inclined guide plate to avoid peanuts remaining in the feeding port 7 when passing through it. For the opening and closing door 8 structure, a common lifting plate structure can be used and embedded inside the housing, and the lifting plate can be driven to move vertically by an electric telescopic rod.

[0031] Furthermore, the feeding channel 5 has an arc-shaped channel structure, with a discharge port at the end of the feeding channel 5 and connected to the baking section 3. As can be seen from the figure, the feeding channel 5 can adopt a C-shaped structure to ensure the smooth transportation of peanuts and reduce damage to peanuts caused by excessive height difference during the transportation of peanuts from top to bottom. In addition, its inner wall can also be filled with a vibrating element 22 structure to minimize the possibility of peanuts remaining in the feeding channel 5.

[0032] In other words, during the pre-processing and transportation of peanuts, the peanuts are first poured into the feeding section 1. After being screened by the screening section 2, impurities are shaken off. After screening, the rotating motor drives the movable screen 21 to swing, causing the movable screen 21 to change from horizontal to inclined, thus forming an inclined slide structure that guides the peanuts toward the feeding port 7. At the same time, the opening and closing door 8 automatically lifts to ensure that the peanuts enter the feeding port 7 and are transported along the feeding channel 5 to the discharge port, and then enter the baking section 3 for pre-processing and baking.

[0033] As a preferred embodiment of this application, such as Figure 3 As shown, the baking section 3 includes a baking drum 31 and a hot air assembly 32. The outer wall of the baking drum 31 is rotatably connected to the rotating table 6 to achieve up-and-down swinging. The hot air assembly 32 is installed inside the baking drum 31.

[0034] Among them, such as Figure 4 and Figure 5 As shown, the baking drum 31 can adopt a traditional cylindrical baking structure, with connecting shafts protruding outward on both sides. The rotating table 6 is a rotating motor structure, which drives the baking drum 31 to rotate at a certain angle through connection with the connecting shaft, thereby achieving the switching between the horizontal baking state and the inclined material conveying state.

[0035] To ensure stability in horizontal baking mode and smooth switching between tilted and conveying modes, multiple retractable support frames 33 can be installed between the baking drum 31 and the housing. The top of the support frame 33 is equipped with an arc-shaped support plate structure, and the bottom can be supported by a hydraulic push rod or an electric telescopic rod structure. When it extends in the horizontal state, it provides stable support for the baking drum 31. When it needs to tilt towards the conveying mode, it can follow the rotation motor to drive the baking drum 31 to swing, realizing the rise and fall of the support frame 33, forming a stepped structure, which ensures normal tilting while also providing a certain support effect.

[0036] Furthermore, such as Figure 3 As shown, the baking drum 31 includes a storage cylinder 311, a positioning cylinder 312, and a drive assembly 313 disposed between the two. The positioning cylinder 312 is provided with double doors on both sides, and the feeding channel 5 is telescopically configured to leave space for opening and closing the doors.

[0037] For the double-door structure, a hinged electric door structure can be adopted. A motor drives the double doors to rotate, realizing the opening and closing actions. Furthermore, since the feeding channel 5 needs to transport peanuts to the inlet of the storage cylinder 311, it will inevitably affect the opening and closing action of the double doors. Therefore, this application provides a telescopic structure at the end of the feeding channel 5. This telescopic structure is as follows: Figure 4 and Figure 5As shown, an additional sliding transport slide 51 structure is provided at the bottom of the original feeding channel 5. It is fixed to the bottom wall of the feeding slide by an electric telescopic rod. When the door needs to be opened, the transport slide 51 is retracted to avoid the opening action. After the door is opened, the transport slide 51 is pushed outward to extend the length of the feeding channel 5 and realize normal feeding. Of course, the other side of the positioning cylinder 312 can also be provided with the same structure as needed, which will not be described in detail here.

[0038] Among them, the storage cylinder 311 is the inner cylinder, which is used to support and roll the peanuts to ensure the normal operation of preheating and baking. The positioning cylinder 312 serves as a protective shell for the storage cylinder 311 on the one hand, and as the mounting position for various drive components 313 and other structures on the other hand, which facilitates maintenance and installation.

[0039] As can be seen from the figure, the drive assembly 313 includes a power component 3131, an output wheel 3132, a transmission wheel 3133, and a transmission belt 3134. The transmission wheel 3133 is sleeved on the outer wall of the storage cylinder 311, and the transmission belt 3134 connects the output wheel 3132 and the transmission wheel 3133. The power component 3131 also uses a rotating motor. For the positioning cylinder 312, a frame structure can be set in the gap between its inner wall and the storage cylinder 311, which can not only improve the stability of the entire baking drum 31, but also facilitate the installation of other internal structures. The power component 3131 is installed on the inner wall of the positioning cylinder 312 and transmits power outward through the output wheel 3132. The diameter of the transmission wheel 3133 is larger than that of the output wheel 3132 and is sleeved on the outer wall of the storage cylinder 311. The output wheel 3132 and the transmission wheel 3133 are on the same plane in the vertical plane and are belt driven by the transmission belt 3134. The power component 3131 drives the storage cylinder 311 to rotate, so as to evenly roast the peanuts inside.

[0040] Understandably, to improve driving capability and stability, two power components 3131 can be set at corresponding positions at both ends of the storage cylinder 311, and two sets of transmission wheels 3133 and transmission belts 3134 can be set to achieve simultaneous driving from both sides. Alternatively, a single power component 3131 with higher output efficiency can be set, and a transmission shaft 3135 can be connected to the center of the output wheel 3132. The transmission shaft 3135 extends all the way to the other side of the storage cylinder 311, and another set of transmission wheels 3133 and transmission belts 3134 can be installed there, which can also achieve stable synchronous driving.

[0041] Of course, in order to further improve the stability of the movement of the storage cylinder 311, a positioning frame structure can be set at both ends of the storage cylinder 311. As can be seen from the figure, the positioning frame structure is similar to a Y-shaped structure with a central rotating shaft, which facilitates rotational engagement with the rotating holes of the frame structure on the inner wall of the positioning cylinder 312, thereby improving the stability of rotation. In addition, multiple sets of rotating wheels 34 can be set on the inner wall of the positioning cylinder 312 to engage with the outer wall of the storage cylinder 311, further improving the smoothness and stability of rotation.

[0042] As a preferred embodiment of this application, such as Figure 3 As shown, the hot air assembly 32 includes a blowing hot air pipe 321 and a radiant hot air pipe 322. The radiant hot air pipe 322 is arranged around the inner wall of the positioning cylinder 312, and the air outlet of the blowing hot air pipe 321 faces the inlet of the storage cylinder 311.

[0043] The hot air blower is located on the outer wall of the positioning cylinder 312. The blowing hot air pipe 321 and the radiant hot air pipe 322 are arranged colinearly. In use, the radiant hot air pipe 322 is spirally arranged on the outer wall of the positioning cylinder 312. It can be positioned by U-shaped locking or by direct screw connection. The hot air blower provides hot air inward to achieve heat radiation to the adjacent placement cylinder, playing a role in auxiliary heating and baking. In order to improve the radiation effect, air vents can be opened in some areas of the radiant hot air pipe 322 to radiate heat to the outer wall of the placement cylinder. Hot air is blown out; the blowing hot air pipe 321 can be connected to the radiant hot air pipe 322, and the two are collinear. The radiant hot air pipe 322 is located in the area near the feeding inlet of the placement cylinder. The blowing hot air pipe 321 can be bent to a certain extent, so that the hot air can be blown into the inside of the placement cylinder to roast the peanuts inside. This allows the peanuts to be directly blown out by the hot air and have their moisture removed, while being supplemented by external heat radiation, which improves the effect and efficiency of pre-processing and roasting, making it more efficient to use.

[0044] As a preferred embodiment of this application, such as Figure 1As shown, the receiving part 4 is located below the baking part 3 and is equipped with a funnel-shaped structure. Specifically, after the peanuts arrive at the feeding channel 5, the baking drum 31 is horizontal, which facilitates the peanuts to enter the baking drum 31 along the curved and inclined feeding channel 5. After the peanuts are conveyed, the feeding channel 5 retracts, the double doors close, the internal placement cylinder begins to rotate, and the hot air fan continuously supplies heat to achieve pre-processing and baking of the peanuts inside. In order to improve the turning effect inside, the inner wall of the placement cylinder can be equipped with a common lifting plate structure to facilitate large-scale turning of the peanuts. To improve the sealing effect, a flexible sealing ring structure can be set on the inner wall surface of the double doors to prevent peanuts from being exposed through the gaps. In addition, to ensure the discharge of moisture and internal ventilation, an air exchange valve can be set on the surface of the double doors at the outlet of the roasting drum 31 to improve the convenience of use. After the pre-processing roasting is completed, the hot air input is stopped, the internal gas is slowly discharged, and then the roasting drum 31 is rotated to change to an inclined material conveying state, and the pre-processed peanuts are slowly poured into the lower receiving part 4 to complete the entire peanut pre-processing roasting process.

At the same time, the electrical components mentioned in this application are all connected to an external power supply and control switch when in use.
