Description

Technical Field

[0001] This application relates to the field of oil pressing equipment, and in particular to an automatic oil pressing device. Background Technology

[0002] In traditional oil pressing processes, the oil pressing process is typically completed using a combination of manual operation and semi-automated equipment. Existing oil pressing equipment generally consists of a feeding device, a roasting pan, an oil press, and a residue removal mechanism. While some steps have been mechanized, key processes still rely on manual intervention. For example, the feeding process often uses manual feeding, requiring operators to control the amount of material fed each time based on experience. However, the lack of precise measurement of material volume, weight, and uniformity makes it difficult to dynamically match the heating temperature and time parameters in the subsequent roasting stage. Since the roasting effect directly affects oil quality and yield, the randomness of manual feeding easily leads to uneven heating of the material. Some materials may become scorched due to excessive roasting time, or the cell walls of the oilseeds may not fully rupture due to insufficient roasting time, ultimately reducing oil extraction efficiency and affecting the stability of the oil's flavor. Furthermore, the oilseeds after roasting need to be manually transferred to the oil press, posing a risk of heat loss during operation, which may further weaken the oil pressing effect. In the residue removal stage, traditional equipment often uses intermittent cleaning methods, requiring frequent shutdowns to handle residue, which not only affects production efficiency but also increases the labor intensity and safety hazards for operators. The root cause of the above problems lies in the lack of full-process automated control capabilities in existing technologies and insufficient coordination between various processes, making it difficult to accurately control process parameters. Therefore, developing a complete set of equipment integrating automatic feeding, intelligent roasting, continuous oil pressing, and real-time residue removal functions has significant application value for improving the standardization level of oil pressing processes, ensuring the consistency of oil quality, reducing labor costs, and achieving large-scale production. Utility Model Content

[0003] The purpose of this application is to overcome at least one deficiency of the prior art and to provide an automatic oil pressing device that achieves fully automated operation throughout the entire process.

[0004] To achieve the above objectives, this application discloses an automatic oil pressing device, which includes a machine body, a hopper, a pre-processing component, a conveying component, and an oil pressing component.

[0005] The lower part of the machine body is provided with a storage bin; the pre-processing component is arranged longitudinally above the storage bin, including a feeding hopper and a roasting unit connected thereto. The feeding hopper forms a material supply link with the storage bin through a vertical lifting mechanism. The lower end of the vertical lifting mechanism is connected to the inside of the storage bin, and the upper end is opposite to the feeding hopper.

[0006] The stir-frying unit has a discharge port and integrates a heating module and a stirring mechanism. It is equipped with a temperature control sensor inside, and the discharge port is equipped with a control valve and connected to the conveying assembly below.

[0007] The conveying assembly is a horizontal spiral conveying mechanism, which is arranged laterally below the roasting unit to convey the roasted material horizontally to the feed end of the oil pressing assembly.

[0008] The oil pressing assembly includes at least one screw pressing mechanism and a continuous slag discharge mechanism connected to the pressing mechanism. The slag inlet of the slag discharge mechanism is matched with the slag outlet of the screw pressing mechanism. The slag outlet extends to the slag collection box outside the machine body and is exposed or has a visible observation window installed on the side wall of the machine body at the position corresponding to the slag discharge path, so as to facilitate observation and understanding of the slag discharge status.

[0009] Furthermore, the oil outlet of the spiral pressing mechanism is connected to a filter assembly installed inside the machine body, which filters the oil.

[0010] Furthermore, the horizontal spiral conveying mechanism includes a U-shaped conveying trough, a spiral conveying component located within the U-shaped conveying trough, and a drive motor, wherein the spiral conveying component is driven to rotate by the motor.

[0011] Compared with existing technologies, this application solves the problems of excessive manual intervention, insufficient process coordination, and low automation in traditional oil pressing processes through automation and intelligent technologies, significantly improving oil pressing efficiency and oil quality consistency. The device achieves precise feeding and dynamic control of roasting parameters, preventing material scorching or incomplete cracking, ensuring stable roasting results, thereby increasing oil yield and optimizing oil flavor. Continuous oil pressing and real-time residue removal reduce the number of downtime cleanings, preventing heat loss and further improving oil pressing efficiency. Simultaneously, the device reduces reliance on manual experience, decreases operator workload and safety hazards, meets the needs of large-scale production, and ensures standardization and quality consistency in the oil pressing process.

[0021] See attached document Figures 1 to 3 In this embodiment of the invention, an automatic oil pressing device is provided, the structural design of which aims to achieve full automation and intelligent control of the oil pressing process as much as possible. The specific structural composition of the device, the connection and cooperation relationships of its components, and its working principle will be described in detail below to ensure that those skilled in the art can fully implement this technical solution.

[0022] The automatic oil pressing device mainly includes a body 1, a storage bin 2, a pre-processing component 3, a conveying component 4, and an oil pressing component 5. The body 1, as the supporting structure of the entire device, is generally made of welded steel to ensure the stability and durability of the overall structure.

[0023] Storage bin 2 is located at the lower part of the machine body 1 and is used to store oilseed raw materials to be processed, such as peanuts, rapeseed, and soybeans. The discharge port of storage bin 2 is connected to the feed end of the vertical lifting mechanism via a flange, ensuring that the material can smoothly enter the subsequent processing stage. Storage bin 2 generally has at least one door that can be opened for replenishment.

[0024] The pre-processing component 3 is arranged longitudinally above the storage bin 2 and includes a feeding hopper 301 and a roasting unit 302 connected thereto. The feeding hopper 301 has an opening and a slope for guiding material towards the opening. When necessary, the top of the feeding hopper 301 is provided with a sealing cover to prevent external impurities from entering.

[0025] The feeding hopper 301 and the storage bin 2 form a material supply link through the vertical lifting mechanism 6.

[0026] It should be understood that the structural design of the vertical lifting mechanism 6 is well-known or existing technology to those skilled in the art, and its specific implementation does not need to be disclosed in detail. Vertical lifting mechanisms are typically used to transport materials from a lower position to a higher position, and common implementation methods include belt conveyors, chain conveyors, or screw conveyors. For example, belt conveyors use a motor to drive a pulley, which in turn drives a food-grade rubber belt to lift materials from a storage silo to a feed hopper; chain conveyors achieve vertical lifting of materials through the cooperation of a chain and a hopper. These technologies are widely used in the field of material handling, and their specific designs and parameter selections can be optimized and implemented by those skilled in the art according to actual needs. Therefore, the specific structure of the vertical lifting mechanism in this application is not described in detail, but its function and role are embodied in the description of the overall device.

[0027] In this embodiment, the roasting unit 302 integrates a heating module and a stirring mechanism, and is equipped with a temperature control sensor. The heating module uses electric heating elements, which are evenly distributed on the outer wall of the roasting unit to ensure that heat can be evenly transferred to the material. The stirring mechanism is driven by a motor, and the stirring paddle adopts a multi-blade design to ensure that the material is heated evenly during the roasting process. The temperature control sensor uses a thermocouple to monitor the roasting temperature in real time, ensuring that the roasting temperature is stable within a preset range (for example, the roasting temperature of peanuts is controlled at 120℃±5℃). The discharge port of the roasting unit 302 is equipped with an electric control valve, which cooperates with the conveying assembly 4 below to ensure that the material can smoothly enter the conveying stage.

[0028] In this embodiment, the conveying component 4 is a horizontal screw conveyor mechanism, arranged laterally below the roasting unit. The horizontal screw conveyor mechanism includes a U-shaped conveying trough, a screw conveyor component located within the U-shaped conveying trough, and a drive motor. The U-shaped conveying trough is made of 304 stainless steel with a wear-resistant coating on its inner wall to ensure smooth and durable material conveying. The screw conveyor component can be a helical spring, with one end connected to the main shaft of the drive motor for rotation. The discharge end of the screw conveyor mechanism is connected to the feed end of the oil pressing component via a flange, ensuring that the material can be continuously fed into the oil pressing stage.

[0029] In this embodiment, the oil pressing assembly 5 includes at least one screw pressing mechanism and a continuous slag discharge mechanism connected to the pressing mechanism. The screw pressing mechanism consists of a pressing chamber and a screw shaft. The pressing chamber is made of high-strength alloy steel to ensure stability and durability under high pressure. The screw shaft is driven to rotate by a high-torque motor to ensure sufficient extrusion force. The surface of the screw shaft is provided with progressive compression threads, which squeeze out the oil from the material through mechanical extrusion.

[0030] It should be noted that, in this embodiment, the structure and working principle of the screw press mechanism are well-known or existing technologies to those skilled in the art, and its specific implementation does not need to be disclosed in detail. A screw press mechanism typically consists of a pressing chamber, a screw shaft, and a drive motor. The mechanical extrusion of the material is achieved through the rotation of the screw shaft and the progressive thread design, thereby separating the oil from the material. This technology has been widely used in oil pressing equipment, food processing, and material pressing fields, and its design and parameter selection can be optimized and implemented by those skilled in the art according to specific needs. Therefore, the specific structure of the screw press mechanism in this application is not described in detail, but its function and role are reflected in the description of the overall device.

[0031] In this invention, the continuous slag discharge mechanism is essentially a screw conveyor mechanism. Its structure and working principle are well-known or existing technologies to those skilled in the art, and its specific implementation does not need to be disclosed in detail. The continuous slag discharge mechanism consists of a slag discharge screw and a drive motor. The slag discharge screw is matched with the slag discharge port of the screw pressing mechanism to continuously discharge the residue to an external slag collection box or slag collection bag.

[0032] It is important to note that a perforated or visible observation window should be installed on the side wall of the machine body corresponding to the slag discharge path. The observation window should be made of high-temperature resistant tempered glass to facilitate operators to monitor the slag discharge status in real time.

[0033] Based on the above structure, to further improve the quality of the extracted oil, the oil outlet of the screw press mechanism is connected to a filter assembly 7 via a pipe. The filter assembly 7 includes a filter chamber and a filter screen and / or filter paper, used to further enhance the purity of the oil. The filtered oil is transported to an external oil storage tank through an oil drain pipe made of food-grade silicone to ensure safety and hygiene during oil transportation.

[0034] In the practical application of this embodiment, the raw materials in the storage silo 2 are conveyed to the feeding hopper 301 via the vertical lifting mechanism 6, and the feeding hopper evenly feeds the material into the roasting unit 302. The roasting unit 302 starts the heating module and turns on the stirring mechanism, and the temperature control sensor monitors the temperature in real time to ensure that the roasting temperature is stable within the preset range. After roasting, the material enters the conveying assembly 4 through the control valve of the discharge port. The conveying assembly 4 conveys the material horizontally to the feeding end of the oil pressing assembly 5 by the rotation of the spiral spring. The screw pressing mechanism squeezes out the oil from the material by mechanical extrusion, while the continuous slag discharge mechanism discharges the residue to the external slag collection box or slag collection bag. The filtration assembly 7 filters the squeezed oil to ensure the purity of the oil.

[0035] In summary, this embodiment essentially achieves full-process control of the oil pressing process, significantly improving oil pressing efficiency and oil quality consistency, reducing labor costs and intensity, and providing reliable technical support for the standardization and large-scale production of oil pressing technology. Those skilled in the art should understand that the above embodiment is only a preferred embodiment of this utility model, and other parts not disclosed in detail (such as the specific model of the motor, the programming logic of the control system, etc.) belong to known and existing technologies in the field, and can be selected and implemented according to specific needs.

[0036] While exemplary embodiments of this disclosure have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this disclosure without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this disclosure as defined by the claims. This disclosure is defined by the appended claims, and equivalents of those claims are also included.
