Description

Technical Field

[0001] This utility model relates to the field of roasting and processing technology, and in particular to a processing device for roasting walnuts. Background Technology

[0002] With the large-scale development of the food processing industry, the market demand for roasted nuts continues to grow. Walnuts, as a high-nutrition, high-value-added roasted product, have made processing efficiency and quality control a key focus of the industry. Traditional walnut roasting equipment largely relies on manual stirring or a single static heating method, which is insufficient to meet the requirements of modern production for automation, efficiency, and standardization. At the same time, consumers have higher expectations for the uniformity of taste, nutrient retention, and food safety standards of nut products, forcing processing technology to upgrade towards intelligent and energy-efficient methods. Against this backdrop, developing new walnut roasting equipment to improve production efficiency and optimize product quality is of significant practical importance.

[0003] Shortcomings of existing technology:

[0004] 1) Poor heating uniformity: Traditional walnut roasting equipment mostly uses static heating (such as heating wires surrounding the heating chamber) or a single stirring device, which cannot achieve synchronous dynamic combination of heating and stir-frying. This easily leads to uneven heating of walnuts, resulting in local scorching or undercooking, affecting the taste and quality stability of the product.

[0005] 2) Low energy efficiency: Some equipment lacks a preheating stage, and the walnuts go directly into the high-temperature roasting stage, which not only increases the load on the main heating components, but also leads to energy waste due to concentrated heat consumption; in addition, equipment with independent drive modules for conveying, stirring, and anti-blocking functions has problems such as complex transmission structure, high energy consumption, and high failure rate.

[0006] 3) Insufficient automation: Existing equipment often requires manual intervention in feeding, mixing or discharging, which is easily affected by the operator's experience and makes it difficult to achieve continuous production; some equipment lacks anti-clogging design, and raw materials are easy to accumulate and block at the feed inlet, resulting in production interruption and reduced processing efficiency. Utility Model Content

[0007] The purpose of this invention is to solve the problems of uneven heating, high energy consumption, and insufficient automation in the existing walnut roasting process, and to propose a processing device for roasting walnuts.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: a processing device for roasting walnuts, comprising a conveying sleeve, a heat conduction chamber fixedly connected to the bottom of the conveying sleeve, a mounting bracket fixedly connected to the outer surface of the heat conduction chamber, a motor fixedly connected to the top of the mounting bracket, a rotating column fixedly connected to the output end of the motor, and upper and lower floating mechanisms provided at both ends of the rotating column; each upper and lower floating mechanism includes a drive shaft, a first pulley fixedly connected to the opposite end of the drive shaft, a drive belt sleeved on the outer wall of each first pulley, a second pulley drivenly connected to the inner wall of each drive belt, a rotating shaft fixedly connected to the outer wall of each second pulley, a drive arm rotatably connected to the outer wall of each rotating shaft, and a second drive arm rotatably connected to the outer wall of each drive arm via a shaft.

[0009] Preferably, a fixed shaft is fixedly inserted into the outer wall of the second transmission arm, and a rotating component is fixedly connected to the opposite ends of the two fixed shafts. A transmission rod is movably inserted into the opposite side of the rotating component. A mounting plate is fixedly connected to both ends of each transmission rod, and a set of diamond-shaped heating components is fixedly connected to the opposite sides of the two mounting plates.

[0010] Preferably, the outer wall of the rotating column is fixedly connected with an auger blade, and the outer wall of the auger blade and the inner wall of the conveying sleeve are in contact with each other.

[0011] Preferably, the bottom of the heat conduction chamber is bolted to a main heating chamber, and the outer wall of the main heating chamber is fixedly connected to a lifting and sealing door.

[0012] Preferably, a material conveying bin is fixedly connected to the top of the main heating chamber, and an anti-blocking rod is movably inserted into the opposite side of the material conveying bin, with the outer surface of the anti-blocking rod fixedly connected to the center of the outer surface of the second pulley.

[0013] Preferably, the outer surface of another second pulley is rotatably connected to the outer surface of the heat conduction chamber via a shaft, the outer surface of each mounting plate is slidably disposed inside the main heating chamber, and the outer surface of each second transmission arm is slidably inserted into the interior of the main heating chamber.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. In this utility model, a single motor drives multiple components to work together. The rotating column drives the auger blades to transport walnuts. At the same time, the rotational motion is converted into the reciprocating linear motion of the diamond-shaped heating components through the upper and lower floating mechanism. Heating and stir-frying are synchronized in the main heating chamber. Combined with the preheating design of the heat conduction holes in the conveying sleeve and heat conduction chamber, a two-stage gradient heating is formed to avoid local overheating and scorching, which significantly improves the uniformity and efficiency of stir-frying. The anti-blocking roller of the conveying chamber and the floating mechanism share the same transmission chain to prevent feeding blockage. The lifting and sealing door of the main heating chamber takes into account both sealing performance and convenient unloading. The modular structure and connecting flange facilitate equipment docking and maintenance. The overall structure is compact, energy-efficient, and suitable for large-scale production.

[0017] 2. In this utility model, the device breaks through the traditional mode of separating static heating and independent stirring in roasting equipment. It reduces component redundancy and maintenance costs with an integrated transmission system. Its anti-blocking, temperature control and material discharge coordinated design further enhances the practicality and reliability of the equipment, providing an efficient solution for walnut roasting and processing.

Detailed Implementation

[0024] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0026] Example 1: Please refer to... Figures 1-5 As shown, this utility model provides a processing device for roasting walnuts, including: a conveying sleeve 1, a heat conduction chamber 11 fixedly connected to the bottom of the conveying sleeve 1, a mounting bracket 12 fixedly connected to the outer surface of the heat conduction chamber 11, a motor 3 fixedly connected to the top of the mounting bracket 12, a rotating column 31 fixedly connected to the output end of the motor 3, and a floating mechanism 2 at both ends of the rotating column 31; each floating mechanism 2 includes a drive shaft 201, a first pulley 202 fixedly connected to the opposite end of the drive shaft 201, a drive belt 203 sleeved on the outer wall of each first pulley 202, a second pulley 204 drivenly connected to the inner wall of each drive belt 203, a rotating shaft 205 fixedly connected to the outer wall of each second pulley 204, a drive arm 206 rotatably connected to the outer wall of each rotating shaft 205, and a second drive arm 207 rotatably connected to the outer wall of each drive arm 206 via a shaft.

[0027] The overall effect of Embodiment 1 is as follows: Core function: Constructing the basic architecture of the power transmission and floating mechanism transmission system; Motor 3 drives the rotating column 31 to rotate, which drives the first pulley 202 to rotate through the transmission shaft 201 at both ends, and drives the second pulley 204 through the transmission belt 203, thereby causing the rotating shaft 205 to drive the transmission arm 206 to perform circular motion. Motion conversion mechanism: The circular motion of the transmission arm 206 is converted into the up-and-down reciprocating swing of the second transmission arm 207 through the shaft connection, providing a power source for the subsequent mounting plate 211 and heating components. Structural significance: Realizing the driving of the floating mechanism by a single motor 3, providing a mechanical motion basis for the dynamic heating module, without the need for additional power components, simplifying the structure.

[0028] Example 2: Please refer to... Figures 1-5As shown, fixed shafts 208 are fixedly inserted into the outer wall of the second transmission arm 207. Rotating parts 209 are fixedly connected to the opposite ends of the two fixed shafts 208. Transmission rods 210 are movably inserted into the opposite sides of the rotating parts 209. Mounting plates 211 are fixedly connected to both ends of each transmission rod 210. A set of rhomboid heating components 212 are fixedly connected to the opposite sides of the two mounting plates 211. Screw blades 32 are fixedly connected to the outer wall of the rotating column 31. The outer wall of the screw blades 32 and the inner wall of the conveying sleeve 1 are in contact with each other. The bottom of the heat conduction chamber 11 is bolted to connect to the main heating chamber 4. The outer wall of the main heating chamber 4 is fixedly connected to the lifting sealing door 41.

[0029] The overall effect of Embodiment 2 is as follows: Core function: Integrating heating components and conveying structure to form a core dynamic heating module for roasting: The second transmission arm 207 drives the mounting plate 211 through the fixed shaft 208, rotating part 209, and transmission rod 210, so that the diamond heating component 212 makes horizontal reciprocating motion in the main heating chamber 4, realizing close-range heating and roasting of walnuts. Spiral conveying is strengthened: The auger blade 32 is attached to the inner wall of the conveying sleeve 1. When rotating, it generates axial pushing force, which uniformly conveys the walnuts from the sleeve feed end to the heat conduction chamber 11. At the same time, it stirs the raw materials and contacts them with hot air (through the heat conduction hole 13) to complete preheating. The roasting space is sealed. The main heating chamber 4 is connected to the heat conduction chamber 11 by bolts. When the lifting and sealing door 41 is closed, it maintains a high temperature environment. When it is open, it facilitates unloading, realizing the switching between "continuous roasting" and "batch operation".

[0030] Example 3: Please refer to... Figures 1-5 As shown, a conveying bin 5 is fixedly connected to the top of the main heating chamber 4. An anti-blocking rod 51 is movably inserted into the opposite side of the conveying bin 5. The outer surface of the anti-blocking rod 51 is fixedly connected to the center of the outer surface of the second pulley 204. The outer surface of the other second pulley 204 is rotatably connected to the outer surface of the heat conduction chamber 11 through a shaft. The outer surface of each mounting plate 211 is slidably disposed inside the main heating chamber 4. The outer surface of each second transmission arm 207 is slidably inserted into the main heating chamber 4. The opposite ends of the two transmission shafts 201 are fixedly connected to the two ends of the rotating column 31. A heat conduction hole 13 is opened on the outer wall of the conveying sleeve 1. Hot air circulates between the conveying sleeve 1 and the heat conduction chamber 11 through the heat conduction hole 13. A connecting flange 14 is fixedly connected to the outer wall of the conveying sleeve 1.

[0031] The overall effect of Embodiment 3 is as follows: core functions: optimized system linkage, improved feeding and heat conduction efficiency, anti-blocking and power sharing: the anti-blocking roller 51 of the conveying bin 5 is fixedly connected to the second pulley 204 through the shaft, and uses the transmission chain of the floating mechanism (driven by the same motor 3) to rotate and stir the raw material to prevent the feed port from being blocked. No independent power source is required, the transmission efficiency is improved, and the heat conduction path is optimized; the heat conduction hole 13 of the conveying sleeve 1 is connected to the heat conduction chamber 11, and hot air flows into the sleeve and exchanges heat with the walnuts pushed by the auger blades 32. The preheated walnuts fall into the main heating chamber 4, reducing the energy consumption of the main heating component. Structural integration and expansion: the second transmission arm 207 penetrates into the main heating chamber 4 and directly drives the mounting plate 211, shortening the transmission path and improving the motion response speed; the connecting flange 14 supports docking with external equipment, adapts to automated production lines, and the raw material processing efficiency can reach 100%.

[0032] Working Principle: Power Input: Motor 3 drives rotating column 31 to rotate, simultaneously driving auger blades 32 (conveying walnuts) and upper and lower floating mechanism 2 (driving heating components). Walnut Conveying and Preheating: Auger blades 32 push walnuts within conveying sleeve 1. Hot air from heat conduction chamber 11 preheats the walnuts through heat conduction holes 13. The walnuts enter the main heating chamber 4 through the bottom of the sleeve. The anti-blocking roller 51 of conveying chamber 5 simultaneously pushes in new raw materials for replenishment. Roasting in main heating chamber 4: The second transmission arm 207 drives mounting plate 211 through linkage mechanism, causing rhomboid heating component 212 to reciprocate, heating... The walnuts are turned over, and the lifting and sealing door 41 controls the discharge. When it is open, the finished product is discharged, and when it is closed, the high temperature environment inside the chamber is maintained. The linkage design is as follows: a single motor 3 drives the conveying, stirring, and anti-blocking functions through a belt pulley transmission chain. The structure is compact and the power distribution is efficient. The core logic is summarized as follows: transmission chain: motor 3 → rotating column 31 → belt pulley group → linkage mechanism → reciprocating motion of heating component. Heating path: preheating of conveying sleeve (hot air convection) → close-range heating of main heating chamber 4 (contact / radiation). Function integration: conveying, stirring, heating and anti-blocking are driven by the same power source, reducing component redundancy.

[0033] The wiring diagrams of the rhomboid heating component 212, motor 3, and lifting sealing door 41 in this utility model are common knowledge in the field. Their working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the control method and wiring layout of the rhomboid heating component 212, motor 3, and lifting sealing door 41 will not be explained in detail.

[0034] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
