Description

Technical Field

[0001] This application relates to a small commercial oil press, specifically an integrated oil pressing device, which is particularly suitable for the efficient pressing and processing of oilseeds in small-scale commercial applications, and relates to the field of food processing machinery technology. Background Technology

[0002] Current commercial oil pressing equipment generally adopts a split-system operation mode, separating processes such as roasting, pressing, and filtering, relying on manual experience to control temperature, pressure, and time parameters. For example, the temperature of the roasting pan needs to be manually adjusted during the oilseed ripening stage, and the cake thickness is adjusted via a mechanical handle to control pressure during pressing. This kind of manual intervention makes it difficult to achieve precise and standardized control, resulting in significant fluctuations in the quality of oil from different batches. More seriously, the multi-stage operation prolongs the exposure time of raw materials during open feeding and transportation, significantly increasing the risk of microbial contamination compared to closed systems, which is particularly prominent in commercial scenarios where food safety standards are becoming increasingly stringent.

[0003] Although integrated oil pressing equipment has emerged in recent years, attempting to improve efficiency through structural integration, its heat transfer system has inherent flaws. The linear heating module of the spiral pressing chamber cannot adapt to the gradient temperature control requirements of different processes such as cold pressing of soybeans and hot pressing of peanuts, resulting in a lower oil extraction rate compared to dedicated equipment. In addition, the existing equipment lacks sufficient intelligence, requiring operators to simultaneously monitor multiple parameters such as motor speed and oil residue separation, placing excessive demands on personnel skills and significantly increasing labor costs and operational error rates in large-scale production. Utility Model Content

[0004] The purpose of this application is to overcome at least one deficiency of the existing technology and provide an integrated oil pressing device that can improve oil pressing efficiency, increase oil yield, prevent dust and pollution, and optimize space utilization. This oil press, through a layered structure design, rationally allocates the functions of each processing stage, ensuring that the oilseeds are fully heated and matured during the pressing process, thereby improving the oil extraction effect. Simultaneously, by improving the material flow path and adding a stirring function, it ensures a fully sealed process while further improving material processing efficiency. This solves the shortcomings of traditional small commercial oil presses in terms of space occupation and processing efficiency, meeting the needs of small commercial users for hygienic, high-quality, efficient, and convenient oil pressing.

[0005] To achieve the above objectives, this application discloses an integrated oil pressing device, which includes a material storage mechanism, a heat treatment mechanism, a material transfer mechanism, a mechanical pressing mechanism, and a controller arranged sequentially from top to bottom within the machine body. Material transfer between the various mechanisms is achieved through a directional flow guide structure.

[0006] The material storage mechanism is located at the top of the machine body. It forms a conical material storage cavity inside and is connected to the bottom discharge port through an inclined guide surface. The discharge port is equipped with an electromagnetic control gate valve that is controlled by the controller to achieve quantitative material feeding control.

[0007] The heat treatment mechanism includes a heating container and a rotating stirring assembly built into the heating container. The heating container has a heating assembly that operates under controller control on its inner wall. Similarly, the stirring assembly, also controlled by the controller, uses a stirring rod or stirring blades to agitate the material. The bottom of the heating container is equipped with an electrically controlled sealing gate that operates under controller control and is connected to the material transfer mechanism.

[0008] The material transfer mechanism adopts an inverted conical transition chamber structure with a flat bottom surface. The flat bottom surface has an opening that connects with the feed inlet of the mechanical pressing mechanism.

[0009] The mechanical pressing mechanism includes a variable diameter screw, a pressing chamber, a variable diameter screw inserted into the pressing chamber, and a motor that drives the variable diameter screw to rotate. The screw surface is provided with progressive compression threads, and the pressing chamber is provided with a slag outlet and an oil outlet, which are used to discharge oil slag and oil, respectively.

[0010] The controller enables time-series linkage control, forming a continuous operation process of raw material pretreatment, thermal processing, pressing, and oil residue separation.

[0011] Furthermore, the material transfer mechanism is equipped with a stirring mechanism controlled by a controller on its flat bottom surface. This stirring mechanism has a pointer-shaped structure and can continuously stir during the material flow process, ensuring that the material enters the mechanical pressing mechanism in sequence. This helps to promote the flowability of the material and avoid the smoothness of the oil pressing process due to material accumulation or solidification.

[0012] Furthermore, the heating container has at least one temperature sensor connected to the controller.

[0013] Furthermore, the mechanical pressing mechanism is provided in two parts, each independently connected to one opening of the material transfer mechanism.

[0014] Furthermore, the inner wall of the pressing chamber is provided with an axially arranged oil guiding channel, which guides the pressed oil to the oil outlet.

[0015] Furthermore, the slag outlet is connected to the slag discharge mechanism, which includes a slag discharge pipe / trough with a screw. The screw is driven to rotate by a motor to push the oil slag along the slag discharge pipe / trough.

[0016] Furthermore, the oil outlet is connected to the filtration mechanism, which includes a pressure vessel, an air pump for supplying gas to the pressure vessel, a filter assembly located inside the pressure vessel for filtering the raw oil, and an oil outlet pipe located outside the pressure vessel and connected to the filter assembly, through which the filtered oil is output.

[0017] Through the aforementioned structural design, the integrated oil pressing device provided in this application addresses the shortcomings of existing technologies. The fully enclosed, stacked structure effectively prevents external contamination during material transfer, a common problem in traditional split-type equipment, and allows for precise control of the oilseed maturation process, resolving the issue of oil quality fluctuations caused by manual operation. Furthermore, the device employs vertically integrated process modules, reducing floor space while optimizing material flow paths to improve processing efficiency. Combined with dynamic stirring components, this ensures the uniformity of oilseed crushing meets industrial production standards. This design, through a combination of structural innovation and process optimization, provides a standardized and intensive oil pressing solution for small-scale commercial applications while ensuring food safety.

[0028] This embodiment discloses an integrated oil pressing device. The overall structure of the device, through design and reasonable layout, ensures the high efficiency and smoothness of the oil pressing process.

[0029] See attached document Figure 1 and 2 The device body 5 includes, from top to bottom, a storage mechanism 1, a heat treatment mechanism 2, a material transfer mechanism 3, a mechanical pressing mechanism 4, and a controller (not shown in the figure).

[0030] The automatic transfer of materials between the various units is achieved through a directional flow structure. The entire process is controlled by an intelligent control system, which optimizes the operation process, increases the oil yield, and reduces the space occupied.

[0031] First, the storage mechanism 1 is located at the top of the machine body 5, and its interior is designed as a conical storage cavity to facilitate material storage and automatic flow. The conical structure, together with the inclined guide surface, effectively guides the material flow to the discharge port at the bottom, ensuring that the material can smoothly enter the next processing stage.

[0032] The discharge port is equipped with an electromagnetic gate valve controlled by a controller. The precise control of the electromagnetic valve enables quantitative feeding, ensuring uniform material distribution throughout the entire processing process and avoiding the impact of uneven material distribution on subsequent stages.

[0033] In this embodiment, refer to the appendix Figure 3 The heat treatment unit 2 includes a heating container, inside which is a rotating stirring assembly 201. The stirring assembly 201 adopts a stirring rod or stirring blade structure (not shown in the figure) to realize the turning and mixing of materials.

[0034] Specifically, the inner wall of the heating container 2 is equipped with multiple heating components (not shown in the figure) controlled by a controller, which ensures that the material is heated evenly during the heating process through precise temperature control.

[0035] The bottom side wall of the heating container 2 is equipped with an electrically controlled sealing gate controlled by a controller, ensuring that the heated material can pass smoothly and connect with the material transfer mechanism 3. This design makes the heating process more efficient and avoids overheating or underheating of the material during the heating process.

[0036] See attached document Figure 4 The material transfer mechanism 3 is designed with an inverted conical transition chamber structure with a flat bottom surface to ensure stable material flow before entering the mechanical pressing mechanism 4. An opening on this bottom surface connects to the feed inlet of the mechanical pressing mechanism 4, ensuring a smooth transition of material to the pressing stage.

[0037] To further improve material flowability, a stirring mechanism 301 controlled by a controller is installed on the flat bottom surface of the material transfer mechanism 3. The stirring mechanism 301 has a pointer-shaped structure and continuously stirs the material during the flow process, preventing material accumulation or solidification from affecting the smoothness of the oil pressing process. This design ensures that the material maintains uniform flow during the transfer process, thereby improving pressing efficiency.

[0038] In the mechanical pressing mechanism, a variable diameter screw and a pressing chamber (not shown in the figure) are designed. The screw surface has a progressive compression thread. Through the rotation of the screw, the material is gradually compressed and the oil is effectively squeezed out.

[0039] In this embodiment, the pressing chamber is equipped with a dedicated slag outlet and an oil outlet to separately discharge the oil residue and oil produced during the pressing process, thereby ensuring a smooth and efficient oil pressing process.

[0040] The slag outlet is located on one side of the pressing chamber, and its function is to discharge solid oil residue produced during the pressing process. As the screw rotates, the material is gradually compressed, and the solid portion (such as the oil residue after pressing) is pushed to one side of the chamber and discharged through the slag outlet. The slag outlet ensures that the oil residue can be discharged smoothly, without accumulating or blocking it in the chamber, which would affect the continuation of the pressing process. The discharge of oil residue also prevents the oil residue from mixing with the oil, ensuring the purity of the oil.

[0041] The oil outlet is located on the other side or below the pressing chamber and is used to discharge the oil squeezed out during the pressing process. The oil is gradually squeezed out by the progressive compression threads on the screw surface and flows towards the oil outlet along the oil guide channels on the inner wall of the pressing chamber. The design of the oil outlet must not only ensure smooth discharge of the oil but also prevent oil from stagnating in the pressing chamber and affecting subsequent pressing processes. To ensure effective oil discharge, the oil outlet is usually equipped with multi-stage filter screens or other filtration devices to remove impurities and ensure the purity of the oil.

[0042] More specifically, in some embodiments, the slag outlet is connected to a slag discharge mechanism (not shown in the figure), which discharges the pressed oil residue through a screw-driven slag discharge pipe or slag discharge trough. The slag discharge mechanism further ensures smooth discharge of the oil residue. Specifically, the slag discharge mechanism includes a motor-driven screw; the rotation of the screw pushes the oil residue outward along the slag discharge pipe or trough until the oil residue is completely discharged. The rotation of the screw not only improves the efficiency of oil residue discharge but also prevents the accumulation of oil residue in the chamber, avoiding interference with the subsequent pressing process. Therefore, this slag discharge mechanism effectively ensures the continuity and stability of the oil pressing process.

[0043] More specifically, in some embodiments, the oil outlet is connected to a filtration mechanism (not shown in the figure). The filtration mechanism further filters the pressed oil, removing impurities and ensuring that the final oil is pure and free of impurities. The filtration mechanism includes a pressure vessel containing a filter assembly for filtering the oil, which is connected to the oil outlet pipe. The oil enters the filtration mechanism through the oil outlet, and an air pump delivers gas into the pressure vessel, increasing the pressure inside. The filter assembly in the pressure vessel uses a high-efficiency filter medium, effectively removing impurities and suspended solids from the oil, ensuring filtration efficiency. During the filtration process, the oil is purified and flows out of the container. The clean oil after filtration is discharged through the oil outlet pipe for subsequent use.

[0044] This design effectively separates the oil and residue during the entire pressing process. The residue is smoothly discharged through the slag discharge mechanism, while the oil is guided to the outlet through the oil guide channel and further purified by the filtration mechanism, ultimately outputting pure oil. Each step of the design has been precisely calculated and optimized to ensure the high efficiency and smoothness of the pressing process and the purity of the oil, meeting the needs of small-scale commercial users for high-quality oil.

[0045] In this embodiment, there are two sets of mechanical pressing mechanisms 4, each connected to one of the two independent openings of the material transfer mechanism 3. Both sets of mechanical pressing mechanisms 4 simultaneously press the material, improving the production efficiency of the device. The motor driving the screw rotation is precisely controlled by a controller, ensuring that the screw speed and pressing pressure can be adjusted according to the different characteristics of the material to achieve the best pressing effect.

[0046] It's important to understand that the controller is the core of the entire oil pressing unit. Through time-series linkage control of each module, it ensures a continuous workflow for raw material pretreatment, heat processing, pressing, and oil residue separation. The controller adjusts the operating status of the heating components based on feedback from temperature sensors, ensuring precise temperature control, and regulates the stirring speed according to the operating status of the stirring component 301. This intelligent control not only improves the efficiency of each stage but also maximizes the smoothness of the oil pressing process.

[0047] Through the above design, the integrated oil pressing device of this embodiment improves oil yield while making full use of the vertical space of the equipment. The stacked structure makes the layout of each functional module more compact, thereby reducing the footprint of the equipment. The coordinated work between the modules makes the entire oil pressing process efficient and smooth, reduces unnecessary intervention during operation, improves oil pressing efficiency, and reduces energy consumption. In addition, the intelligent design of the control system makes the operation of the device simpler, even for novice users.

[0048] 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.
