Description

Technical Field

[0001] This utility model relates to the field of oil pressing equipment technology, specifically a closed continuous oil press. Background Technology

[0002] An oil press is a machine that uses mechanical force to increase temperature, activate oil molecules, and squeeze oil out of oilseeds. Oil presses can be divided into household oil presses, hydraulic oil presses, screw oil presses, new hydraulic oil presses, high-efficiency fine filter oil presses, and fully automatic oil presses.

[0003] Existing Patent 1: A continuous oil press, such as patent publication number CN221913387U, includes a frame; it also includes a feeding assembly installed on the top of the frame, the feeding assembly including several feeding cylinders arranged vertically on the frame, one end of the feeding cylinder being the feeding cylinder inlet and the other end being the feeding cylinder outlet, a feeding shaft being fixedly installed inside the feeding cylinder, and feeding plates for conveying materials being fixedly installed on the inner circumferential surface of the feeding cylinder; it also includes an oil pressing assembly installed on the bottom of the frame, the oil pressing assembly including a screw oil press, one end of the screw oil press being the screw oil press inlet and the other end being the screw oil press cake outlet, the oil outlet of the screw oil press being located between the screw oil press inlet and the screw oil press cake outlet, the outlet of the feeding cylinder located at the bottom being connected to the screw oil press inlet; it also includes an oil storage tank, the oil storage tank being located below the oil outlet of the screw oil press;

[0004] Existing Patent 2: For example, a multi-functional oil pressing device with patent publication number CN216427238U includes a main body with a feeding mechanism; a roasting mechanism for steaming and roasting oil crops, wherein the discharge end of the feeding mechanism is connected to the inlet end of the roasting mechanism to supply the roasting pan; an oil pressing device, wherein the discharge end of the roasting mechanism is connected to the inlet end of the oil pressing device to supply the oil pressing device; and a preliminary filtration device, wherein the discharge end of the oil pressing device is connected to the inlet end of the preliminary filtration device via a feed pump I to supply the preliminary filtration device. The system includes: a material feeder; a mixing tank, wherein the oil outlet of the primary filtration device is connected to the feed inlet of the mixing tank to supply the material to the mixing tank; a secondary filtration device, wherein the discharge end of the mixing tank is connected to the feed inlet of the secondary filtration device via a material pump II to supply the material to the secondary filtration device; a storage tank, wherein the oil outlet of the secondary filtration device is connected to the inlet of the storage tank to collect and store the oil; and a controller having a display terminal and an input terminal, wherein the controller is electrically connected to the feeding mechanism, the roasting mechanism, the oil pressing equipment, the primary filtration device, the mixing tank, and the secondary filtration device, respectively.

[0005] Since we began producing and selling the two products mentioned above, after numerous tests, we have found that both devices have room for improvement. For existing Patent 1, since the feed inlet of the feeding assembly is at the top of the oil press, an external screw feeder is required for adding materials. This structure requires further installation during use, and its roasting mechanism generally lacks a cover, resulting in a non-enclosed structure that leads to rapid heat loss and low thermal efficiency during roasting. For existing Patent 2, this device includes conventional roasting and pressing functions as well as sterilization and filtration functions. While the device has a high degree of integration, it also results in disorganized and bulky stacking. Furthermore, because the pressing equipment is installed inside the machine, adjusting the oil output requires accessing the main body of the machine, which is inconvenient.

[0006] Based on this, we have made further technical improvements to the two existing machines to enhance the rationality of the equipment structure and improve their steaming and frying efficiency. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a closed continuous oil press with a more reasonable structure and higher thermal efficiency in frying materials, in order to address the shortcomings of the existing technology.

[0008] The technical problem to be solved by this utility model is achieved through the following technical solution: a closed continuous oil press, including a frame, which is equipped with;

[0009] The feeding mechanism includes a hopper I and a feeder. The hopper I is located on the bottom outer wall of the frame, and the feeder is located inside the frame. The discharge end of the hopper I is connected to the feed end of the feeder, thereby feeding the feeder.

[0010] The steaming and frying equipment placed inside the frame has a sealing cover on top. The discharge end of the feeder extends into the steaming and frying equipment through the sealing cover to supply material to the steaming and frying equipment.

[0011] The hopper II, located inside the frame, has its feed end at the discharge end of the steaming and frying equipment, thus receiving the steamed and fried material.

[0012] The oil pressing equipment is placed inside the frame. The discharge end of hopper II is connected to the feed end of the oil press to supply the oil to the equipment. The oil discharge end of the oil pressing equipment is located inside the frame, and the residue discharge end of the oil pressing equipment extends outside the frame.

[0013] The oil storage tank, located inside the frame, is situated below the oil discharge end of the oil pressing equipment to collect the oil.

[0014] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the closed continuous oil press described above, wherein the steaming and frying equipment is a flat-bottomed stirring and frying pan.

[0015] The technical problem to be solved by this utility model can also be achieved through the following technical solution: the closed continuous oil press described above has a pressure relief and exhaust pipe installed on the sealing cover, which extends to the top of the machine frame.

[0019] Compared with the prior art, the beneficial technical effects of this utility model are:

[0020] (1) By integrating the feeding mechanism, steaming and frying equipment, oil pressing equipment and oil storage tank into a closed frame, and adding a sealing cover to the flat bottom stirring and frying pan, the heat loss of the steaming and frying equipment can be significantly reduced. This ensures the steaming and frying operation to the greatest extent, while also blocking most of the external dust pollution, ensuring the hygienic quality of the oil to a certain extent, and reducing the cost of subsequent fine filtration.

[0021] (2) The steaming and frying equipment is located above the oil pressing equipment. After steaming and frying, the oil material falls automatically through hopper II, reducing the energy consumption of conveying. Hopper I is directly connected to the built-in screw feeder, eliminating the need for external feeder installation steps and shortening the preparation time for oil pressing. In addition, the residue outlet of the oil pressing equipment extends to the outside of the frame, and the oil outlet is built-in and aligned with the oil storage tank. The output / cake quantity can be adjusted without entering the equipment, making it more user-friendly.

[0022] (3) A pressure relief exhaust pipe with a pressure relief valve is added to the sealing cover, which can automatically release the overpressure steam accumulated during the steaming and frying process, and avoid the risk of pressure accumulation inside the frying equipment by releasing pressure in a positive pressure venting manner.

The hopper I 3 and the hopper II 4 below form a roughly funnel shape. The specific size and shape can be selected according to the usage requirements. The feeder 2 is located inside the frame 1. The feeder 2 is a screw feeder 2. The discharge end of the hopper I 3 is connected to the feed end of the feeder 2 to feed the feeder 2. The angle between the screw feeder 2 and the horizontal plane can be selected according to the usage requirements, for example, 75°. The specific degree is not limited to this.

[0028] The steaming and frying equipment 5 is placed inside the frame 1. A sealing cover is provided on the top of the steaming and frying equipment 5. The discharge end of the feeder 2 extends into the steaming and frying equipment 5 through the sealing cover to supply the steaming and frying equipment 5. The steaming and frying equipment 5 is a flat-bottomed stirring and frying pan. The flat-bottomed stirring and frying pan can be a vertical frying machine with an internal stirring mechanism. The stirring mechanism can be composed of a motor and a stirring plate. This is existing technology. The specifications and models can be selected according to the usage requirements. Since the current frying machines do not have a cover, we have added a sealing cover 6 to increase its sealing performance. A through hole can be opened on the sealing cover 6 for the discharge end of the screw feeder 2 to extend into.

[0029] The aforementioned sealing cover 6 can be a round cover structure, and a sealing ring can be added to the top edge of the flat-bottomed stirring wok. The material of the sealing ring can be selected according to the usage requirements, such as silicone. A pressure relief exhaust pipe 7 is installed on the sealing cover 6, which extends to the top of the frame 1 to relieve pressure on the steaming and frying equipment 5.

[0030] It should be noted that since the steaming and frying equipment 5 is under positive pressure during steaming and frying, excess heat will be automatically discharged through the pressure relief exhaust pipe 7.

[0031] The hopper II4, placed inside the frame 1, has its feed end located at the discharge end of the steaming and frying equipment 5, thereby receiving the steamed and fried material.

[0032] The oil pressing equipment 8 is placed inside the frame 1. The steaming and frying equipment 5 is located above the oil pressing equipment 8. The discharge end of the hopper II 4 is connected to the feed end of the oil press to supply material to the oil pressing equipment 8. The oil discharge end of the oil pressing equipment 8 is located inside the frame 1, and the residue discharge end of the oil pressing equipment 8 extends outside the frame 1. The oil pressing equipment 8 is a screw oil press.

[0033] The oil storage tank 9, placed inside the frame 1, is located below the oil discharge end of the oil pressing equipment 8, thereby collecting the oil. The oil storage tank 9 is formed into a roughly square tank structure.

[0034] The steaming and frying zone of the closed continuous oil press in Example 1 has a closed structure. Its sealing design allows the heat in the steaming and frying equipment 5 and the frame 1 to dissipate more slowly, thereby ensuring the steaming and frying effect.

[0035] In addition, the residue discharge end of the oil pressing equipment 8 is located outside the frame 1. This design allows operators to adjust the cake discharge gap of the oil pressing equipment 8 without having to enter the frame 1, which facilitates the operation and adjustment by the operators.
