Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically to an electric rice and flour press. Background Technology

[0002] Manual piston presses for pressing rice noodles and vermicelli have a long history and are still widely used in restaurants, canteens, food stalls, and hotels. However, these manual piston presses require manual labor, resulting in low efficiency, difficulty in quality control, and high labor costs. With societal development, people have increasingly higher demands for food quality and hygiene, as well as for the aesthetics, safety, and ease of operation of presses. Automatic pressing has become the trend. Currently, there are two main types of commercial automatic presses on the market: hydraulic presses and screw presses. Hydraulic presses use hydraulic cylinders to drive the pressing piston up and down to press rice noodles or vermicelli. Hydraulic presses are powerful but also large, requiring a large area and incurring high costs. Screw presses, especially single-screw presses, use a large-groove screw to convey and press rice or dough, allowing for continuous operation. They are typically used in stores with high customer volume. Their disadvantages include a large amount of residue inside the screw, making cleaning difficult, and the equipment is difficult to manufacture, large in size, and expensive.

[0003] Chinese utility model patent CN209251658U discloses a rice noodle press, including a frame, support rod, fixed frame, clamping member, pressing member, pressing cylinder, and pressing mechanism. The support rod is rotatably mounted on the frame, and the fixed frame is mounted on the support rod. The clamping member includes a first clamping plate and a second clamping plate. The first clamping plate is fixedly mounted on the fixed frame, and the second clamping plate is detachably mounted on the fixed frame. The pressing member is mounted on the fixed frame and can rotate relative to the fixed frame under force to press or release the second clamping plate. The pressing cylinder is clamped between the first clamping plate and the second clamping plate. The top of the pressing cylinder is open, and the bottom of the pressing cylinder has a plurality of forming holes spaced apart. The pressing mechanism includes a pressing piston and a pressing drive member. The pressing drive member is mounted on the fixed frame and connected to the pressing piston to drive the pressing piston to extend into the pressing cylinder from the top opening of the pressing cylinder for pressing operations. This rice noodle press utilizes the cooperation of a first clamping plate, a second clamping plate, and a pressing component to disassemble and assemble the pressing cylinder, separating the pressing cylinder from the pressing piston for easy cleaning. However, the disassembly and assembly process requires rotating the pressing component to release the second clamping plate, and then removing the second clamping plate from the mounting bracket before the pressing cylinder can be removed, making the disassembly and assembly steps rather cumbersome. Utility Model Content

[0004] To address the aforementioned problems, it is necessary to provide an electric rice and flour press that allows for easy disassembly of the pressing cylinder.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An electric rice and flour pressing machine includes a frame and a pressing assembly mounted on the frame. The pressing assembly includes a mounting base, a support plate, a pressing cylinder, a pressing drive component, and a pressing piston. The mounting base is connected to the frame. The support plate is mounted on the bottom of the mounting base and has a through groove. The mounting base and / or the support plate are also equipped with a limiting member, which forms a limiting groove between the limiting member and the top surface of the support plate. A supporting flange protrudes from the outer peripheral wall of the pressing cylinder. A plurality of forming holes are spaced apart on the bottom surface of the pressing cylinder. The pressing cylinder slides through the groove, and the supporting flange is supported on the top surface of the support plate. The pressing cylinder can slide along the groove under force, so that the supporting flange is engaged in or removed from the limiting groove. The pressing drive component is mounted on the mounting base and connected to the pressing piston to drive the pressing piston to extend into the pressing cylinder for pressing operations.

[0006] Furthermore, the mounting base is provided with two sets of limiting members, which are located on opposite sides of the slide groove. Each set of limiting members includes several limiting plates spaced apart along the length of the slide groove. The limiting plates and the top surface of the support plate form the limiting groove.

[0007] Furthermore, the tray is horizontally arranged, one end of the slide extends to the bottom of the mounting base, and the other end of the slide extends out of the mounting base; both sets of limiting members are located at the end of the slide that is directly below the mounting base.

[0008] Furthermore, the pressing cylinder is able to slide along the slide groove in a working position and a disassembly position: when the pressing cylinder is in the working position, the pressing cylinder moves to the end of the slide groove located directly below the mounting base, and the opposite sides of the supporting flange are respectively engaged in the corresponding limiting grooves; when the pressing cylinder is in the disassembly position, the pressing cylinder moves to the end of the slide groove away from the mounting base, and the supporting flange disengages from the corresponding limiting groove, so as to facilitate the installation and disassembly of the pressing cylinder.

[0009] Furthermore, the frame includes a base, a telescopic rod, and a fixed frame. The two ends of the telescopic rod are respectively connected to the base and the fixed frame, and the mounting base is detachably connected to the fixed frame.

[0010] Furthermore, the fixing frame includes a frame body and two extension arms that protrude from the side of the frame body at intervals, and a groove is recessed on the top surface of each extension arm; hooks are provided on the outer walls of opposite sides of the mounting base, and the mounting base is located between the two extension arms and is engaged with the corresponding grooves through the hooks.

[0011] Furthermore, the hook includes a hanging rod and a limiting plate fixedly connected to one end of the hanging rod. The end of the hanging rod away from the limiting plate is fixedly connected to the outer wall of the mounting base. When the hook is in a snap-fit ​​state with the corresponding slot, the hanging rod is inserted into the slot, and the limiting plate can abut against the side of the extension arm facing away from the mounting base.

[0012] Furthermore, the base includes a seat body, a sleeve, and two locking bolts. The sleeve is fixedly connected to the seat body, and the end of the telescopic rod away from the fixed frame is rotatably inserted into the sleeve. Two elastic clamps are provided at intervals on the end of the sleeve away from the seat body. The two elastic clamps are located on opposite sides of the telescopic rod, and a lug is provided on each opposite side of the elastic clamp. The two locking bolts are respectively located on opposite sides of the elastic clamps and pass through the lugs on the corresponding sides of the two elastic clamps.

[0013] Furthermore, the forming hole extends through the bottom wall of the pressing cylinder along the axial direction of the pressing cylinder, the top opening of the forming hole is connected to the pressing cylinder, and a chamfer is provided at the top opening of the forming hole.

[0014] Furthermore, the pressing drive component is an electric push rod.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects: (1) The electric rice and flour press of this utility model can position the press cylinder when the supporting flange of the press cylinder is locked in the corresponding limiting groove, thus preventing the press cylinder from moving randomly during the operation of the rice and flour press. When the press cylinder needs to be disassembled for cleaning, the press cylinder can be disassembled simply by moving it along the slide groove so that the supporting flange can be released from the limiting groove. This makes it more convenient to use.

[0016] (2) The electric rice and flour press of this utility model has a detachable connection between the mounting base of the pressing component and the fixing frame of the machine frame, so that the pressing component can be installed on the machine frame for use, or it can be taken out from the machine frame and used as a portable household electric noodle press, thus making it suitable for a variety of occasions.

[0017] (3) The electric rice and flour press of this utility model has a frame including a telescopic rod and the telescopic rod is rotatably mounted on the base of the frame. When in use, the height and position of the pressing cylinder and its position on the horizontal plane can be flexibly adjusted as needed to meet different usage scenarios.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] Please also see Figure 1 and Figure 2 The present invention provides an electric rice and flour press 100 according to a preferred embodiment, which includes a frame 10 and a pressing assembly 30 mounted on the frame 10.

[0034] The frame 10 includes a base 11, a telescopic rod 13, and a fixing frame 15. The two ends of the telescopic rod 13 are connected to the base 11 and the fixing frame 15, respectively. Please refer to [other documentation / references]. Figure 3In this embodiment, the base 11 includes a seat body 112, a sleeve 113, and two locking bolts 116. The seat body 112 is generally a support structure. In other embodiments, wheels can be installed on the seat body 112 to facilitate the overall movement of the electric rice and flour press 100. The sleeve 113 is fixedly connected to the seat body 112. In other embodiments, the sleeve 113 is vertically arranged, and its bottom end is fixedly connected to the seat body 112. Two elastic clamping plates 114 are provided at intervals at one end of the sleeve 113 away from the seat body 112. Each elastic clamping plate 114 has a lug 115 protruding from its opposite sides. The two locking bolts 116 are respectively located on opposite sides of the elastic clamping plates 114 and pass through the lugs 115 on the corresponding sides of the two elastic clamping plates 114. The locking bolt 116 has a prior art structure, comprising a bolt (not shown) with a bolt head and a nut (not shown) threadedly connected to the bolt. When the locking bolt 116 is installed, the bolt passes through lugs 115 on corresponding sides of the two elastic clamping plates 114, and the lugs 115 on corresponding sides of the two elastic clamping plates 114 are located between the bolt head and the nut. In this embodiment, the elastic clamping plates 114 can be made of an elastic metal material and are arc-shaped plates.

[0035] One end of the telescopic rod 13 is rotatably inserted into the sleeve 113, and two elastic clamping plates 114 are located on opposite sides of the telescopic rod 13. In this embodiment, the telescopic rod 13 is vertically arranged, and the bottom end of the telescopic rod 13 passes between the two elastic clamping plates 114 and is rotatably inserted into the sleeve 113. In use, rotating the nut causes it to move closer to the bolt head, which causes the two elastic clamping plates 114 to elastically deform and move closer to each other, thereby firmly clamping the telescopic rod 13 and preventing the telescopic rod 13 from rotating relative to the sleeve 113, thus achieving rotational locking of the telescopic rod 13. When the nut is rotated in the opposite direction, moving it away from the bolt head, the two elastic clamping plates 114 move away from each other and reset under the action of elastic restoring force, thereby releasing the telescopic rod 13, allowing the telescopic rod 13 to rotate relative to the sleeve 113 under the action of external force. The telescopic rod 13 can adopt a sleeve-type telescopic rod structure available on the market, such as the telescopic rod described in the Chinese utility model patent with announcement number CN222038400U. To save space, it will not be described in detail here.

[0036] The fixing frame 15 is fixed to the end of the telescopic rod 13 away from the base 11. In this embodiment, the fixing frame 15 includes a frame body 151 and two extension arms 153 that protrude from the side of the frame body 151 at intervals. The frame body 151 is fixedly connected to the end of the telescopic rod 13 away from the base 11; the extension arms 153 are substantially perpendicular to the telescopic rod 13. A slot 154 is recessed on the top surface of each extension arm 153. In this embodiment, a plurality of slots 154 are recessed on the top surface of each extension arm 153, and the plurality of slots 154 are spaced apart along the length direction of the extension arm 153.

[0037] Please see also Figure 5 and Figure 6 The pressing assembly 30 includes a mounting base 31, a support plate 32, a pressing cylinder 33, a pressing drive component 34, and a pressing piston 35. The mounting base 31 is connected to the frame 10, the support plate 32 is mounted on the bottom of the mounting base 31, the pressing cylinder 33 is detachably mounted on the support plate 32, and the pressing drive component 34 is mounted on the mounting base 31 and connected to the pressing piston 35 to drive the pressing piston 35 to extend into the pressing cylinder 33 for pressing operations.

[0038] In this embodiment, the mounting base 31 has a mounting cavity 310 that extends through the bottom surface of the mounting base 31. The mounting base 31 is detachably connected to the fixing frame 15, as detailed below: (Please refer to...) Figure 4 The mounting base 31 has hooks 311 on its outer walls on opposite sides, corresponding to the slots 154 of the two extension arms 153. The mounting base 31 is located between the two extension arms 153, and the hooks 311 engage with the slots 154 on the corresponding sides. In this embodiment, the hooks 311 include a hanging rod 312 and a limiting plate 314 fixedly connected to one end of the hanging rod 312. The end of the hanging rod 312 away from the limiting plate 314 is fixedly connected to the outer wall of the mounting base 31. When the hooks 311 are engaged with the slots 154 on the corresponding sides, the hanging rod 312 is engaged in the slots 154, and the limiting plate 314 can abut against the side of the extension arm 153 facing away from the mounting base 31 to limit the position of the pressing assembly 30 on the fixed frame 15 and prevent the mounting base 31 from accidentally detaching from the frame 10. Furthermore, in this embodiment, the hook 311 is positioned near the top surface of the mounting base 31, which makes the center of gravity of the pressing assembly 30 more stable.

[0039] In this embodiment, the tray 32 is horizontally arranged. A sliding groove 321 is formed through the tray 32, and the sliding groove 321 communicates with the mounting cavity 310 in the mounting base 31. Specifically, the sliding groove 321 is generally waist-shaped, one end of the sliding groove 321 extends to the bottom of the mounting base 31 to communicate with the mounting cavity 310, and the other end of the sliding groove 321 extends out of the mounting base 31.

[0040] Please see also Figures 7 to 9The tray 32 and / or mounting base 31 are also equipped with limiting members 36, which form a limiting groove 361 between the limiting members 36 and the top surface of the tray 32. In this embodiment, the bottom of the mounting base 31 is provided with two sets of limiting members 36, which are located on opposite sides of the slide groove 321. Each set of limiting members 36 includes several clamping plates 360 spaced apart along the length of the slide groove 321. The clamping plates 360 are fixed to the inner wall of the mounting cavity 310 and form the limiting groove 361 between themselves and the top surface of the tray 32. It is understood that in other embodiments, the clamping plates 360 can also be fixed to the tray 32, as long as they can form the limiting groove 361 between themselves and the top surface of the tray 32.

[0041] Please see also Figure 10 and Figure 11 The pressing cylinder 33 is used to hold rice balls, dough, and other materials awaiting pressing. The pressing cylinder 33 has an opening at the top, and a supporting flange 331 protrudes from the top periphery of the pressing cylinder 33. Several forming holes 332 are spaced apart on the bottom surface of the pressing cylinder 33. The pressing cylinder 33 slides through a groove 321, and the supporting flange 331 is supported on the top surface of the support plate 32. The pressing cylinder 33 can slide along the groove 321 under force, so that the opposite sides of the supporting flange 331 are respectively engaged in or removed from the limiting grooves 361 of the two sets of limiting members 36. Specifically, the pressing cylinder 33 can slide along the slide groove 321 in a working position and a disassembly position: when the pressing cylinder 33 is in the working position, it moves to the end of the slide groove 321 directly below the mounting base 31, and the opposite sides of the supporting flange 331 are respectively engaged in the corresponding limiting grooves 361; when the pressing cylinder 33 is in the disassembly position, it moves to the end of the slide groove 321 away from the mounting base 31, and the supporting flange 331 disengages from the corresponding limiting grooves 361, so as to facilitate the installation and disassembly of the pressing cylinder 33. The shape of the forming hole 332 is designed according to the required shape of the vermicelli or noodles, and can be designed as a round hole, a rectangular hole, etc., which can be selected according to the needs of different customers. In this example, a small round hole with a diameter of 1.8mm is used. The forming hole 332 extends through the bottom wall of the pressing cylinder 33 along the axial direction of the pressing cylinder 33. The top of the forming hole 332 is connected to the pressing cylinder 33, and the top periphery of the forming hole 332 is provided with a chamfer 334, which makes the surface of the extruded vermicelli or noodles smoother and the extrusion process smoother.

[0042] Please see again Figure 6In this embodiment, the pressing drive 34 is an electric push rod. The electric push rod has a prior art structure, comprising a drive body 341 and a push rod 343 connected to the drive body 341. The drive body 341 can drive the push rod 343 to extend and retract. Two limit switches (not shown) are installed inside the push rod 343, corresponding to the extreme positions of extension and retraction, respectively. The drive body 341 is fixed within the mounting cavity 310 of the mounting base 31, and the free end of the push rod 343 is fixedly connected to the pressing piston 35. The drive body 341 can drive the push rod 343 to extend and retract vertically, thereby driving the pressing piston 35 to extend into the pressing cylinder 33 through the top opening of the pressing cylinder 33 for pressing operations. In this embodiment, the extreme position of the push rod 343's extension is when the pressing piston 35 contacts the inner bottom wall of the pressing cylinder 33; the extreme position of the push rod 343's retraction is when the pressing piston 35 retracts to a position disengaged from the pressing cylinder 33. It is understandable that the upper and lower limits of the push rod 343's extension can be set via a controller (such as a PLC controller). The controller automatically cuts off the power after receiving the arrival signal. Limiting the upper and lower limits of the push rod 343's extension is existing technology and will not be elaborated here for brevity. The maximum thrust, stroke, extension speed, and power of the electric push rod are determined based on the diameter and height of the pressing cylinder 33 and the hardness of the rice or dough being pressed. From a commercial perspective, this embodiment uses a pressing cylinder 33 with an inner diameter of 100mm and a height of 150mm, which can press 6-8 bowls of rice noodles (about 3 liang) at a time. Therefore, a 1.2T electric push rod is used. In addition, during the pressing operation, the outer circumference of the pressing piston 35 inside the pressing cylinder 33 can be in sealed contact with the inner circumference of the pressing cylinder 33 to prevent material leakage from the gap between the pressing piston 35 and the pressing cylinder 33 during the pressing process.

[0043] When using the electric rice and flour press 100, firstly, install the pressing assembly 30 onto the frame 10. Specifically, insert the pressing assembly 30 between the two extension arms 153 from above, and then move the pressing assembly 30 downwards until the hook 311 of the mounting base 31 engages with the corresponding slot 154 on the extension arm 153. Next, insert the pressing cylinder 33 from top to bottom into the end of the slide groove 321 of the support plate 32 furthest from the mounting base 31, so that the pressing cylinder 33 is in the unloading position, until both sides of the supporting flange 331 of the pressing cylinder 33 are supported on the support plate 32. Then, pour the dough or rice ball to be pressed into the pressing cylinder 33. Subsequently, the pressing cylinder 33 is slid towards the mounting base 31 until it reaches the end of the slide groove 321 closest to the pressing cylinder 33, thus positioning the pressing cylinder 33 in the working position. At this point, the support flange 331 is located within the mounting cavity 310 of the mounting base 31 and engaged in the limiting groove 361, with the pressing cylinder 33 abutting against the end of the slide groove 321 closest to the pressing cylinder 33. Finally, the electric rice and noodle press 100 is started, and the pressing piston 35 is driven by the pressing drive component 34 to extend into the pressing cylinder 33 from the top opening and move towards the forming hole 332, extruding the dough or rice ball inside the pressing cylinder 33 through the forming hole 332 to form strips of rice flour or noodles. The formed rice flour or noodles automatically fall into a container below the pressing cylinder 33 for storage under gravity or directly into a cooking pot for steaming and cooking for further processing.

[0044] When the dough or rice ball in the pressing cylinder 33 is used up, that is, when the pressing piston 35 contacts the inner bottom surface of the pressing cylinder 33, the pressing drive 34 drives the pressing piston 35 to move away from the forming hole 332 until the pressing piston 35 is outside the pressing cylinder 33. Then, the pressing cylinder 33 is slid away from the mounting base 31 until the pressing cylinder 33 is in the unloading position away from the mounting base 31. At this time, dough or rice ball can be added to the pressing cylinder 33 again, and then the pressing cylinder 33 with the dough or rice ball is moved along the slide groove 321 to the working position for pressing. Alternatively, after moving the pressing cylinder 33 to the unloading position away from the mounting base 31, the pressing cylinder 33 can be directly pulled out from the support plate 32, and then another pressing cylinder 33 with dough or rice ball is installed on the support plate 32 in the same way as described above. After pressing is completed, the pressing cylinder 33 can be removed in accordance with the above method to clean the pressing cylinder 33 and the pressing piston 35. The pressing piston 35 can be wiped with a clean cloth.

[0045] In one embodiment, the movement of the pressing drive 34 can be controlled by six buttons: pressing 1 liang (50g), 2 liang (100g), 3 liang (150g), continuous pressing, piston return, and stop. The first four buttons (pressing 1 liang, 2 liang, 3 liang, and continuous pressing) control the running time of the electric push rod via a time controller to achieve quantitative pressing. The method of controlling the running time of the electric push rod via a time controller is prior art; for example, refer to the sampling device for feed production disclosed in Chinese Utility Model Publication No. CN220708832U, which discloses that the working state of the electric push rod can be controlled by setting the time with a time controller. The piston return button directly controls the pressing drive 34 to move the pressing piston 35 upwards, and the stop button can stop the movement of the pressing piston 35 at any time. The six buttons are mounted on a button box, which can be installed in a convenient location according to user needs, such as above or in front of the noodle cooker. More specifically, the buttons for pressing 1 liang, 2 liang, 3 liang, and continuous pressing are electrically connected to four time controllers (i.e., time relays). Each of the four time controllers has a different working duration corresponding to the "press 1 liang, 2 liang, 3 liang, and continuous pressing" buttons. For example, assuming calculations and verification show that the electric push rod can press 1 liang of rice noodles or noodles, 2 liang of rice noodles or noodles, 3 liang of rice noodles or noodles, and completely press the material in the pressing cylinder 33 after working for h1, h2, h3, and h4 respectively, the positive terminal of the power supply is connected to the power input terminal of the time relay, and the negative terminal is connected to the negative terminal of the electric push rod. One end of each of the pressing 1 liang, pressing 2 liang, pressing 3 liang, and continuous pressing buttons is connected to the coil input terminal of the corresponding time controller, and the other end is connected to the positive terminal of the power supply. The normally open contacts of all four time controllers are connected to the positive terminal of the electric push rod. The required working time for the electric push rod is set on four time controllers. For example, the time controller corresponding to the two buttons for Press 1 is set to h1, the time controller corresponding to the two buttons for Press 2 is set to h2, the time controller corresponding to the two buttons for Press 3 is set to h3, and the time controller corresponding to the continuous pressing button is set to h4. In use, when the two buttons for Press 1 are pressed, the coil of the time relay connected to the two buttons for Press 1 is energized, the normally open contact closes, and the electric push rod begins to move. After the set time (h1), the normally open contact of the time relay opens, and the electric push rod stops moving. The principle of the two buttons for Press 2, Press 3, and the continuous pressing button is similar and will not be described further here. The piston return button can be connected to the "retraction" control input terminal of the electric push rod. Pressing the piston return button causes the electric push rod to move in the reverse direction, causing the push rod 343 to drive the pressing piston 35 upwards to disengage from the pressing cylinder 33. The stop button can be connected to the "stop" control input of the electric linear actuator. Pressing the stop button will de-energize the electric linear actuator and stop its operation. Controlling the retraction and stopping of the electric linear actuator via a button is existing technology and will not be described in detail here for the sake of brevity.

[0046] The electric rice and flour press 100 of this utility model can position the press cylinder 33 when the supporting flange 331 of the press cylinder 33 is engaged in the limiting groove 361, thus preventing the press cylinder 33 from moving randomly during the operation of the electric rice and flour press 100. When it is necessary to disassemble the press cylinder 33 for cleaning, it is only necessary to move the press cylinder 33 along the sliding groove 321 so that its supporting flange 331 is disengaged from the limiting groove 361 to disassemble the press cylinder 33, making it more convenient to use.

[0047] The electric rice and flour press 100 of this utility model has a detachable connection between the mounting base 31 of the pressing component 30 and the fixing frame 15 of the frame 10, so that the pressing component 30 can be installed on the frame 10 for use, or it can be taken out of the frame 10 for use as a portable household electric noodle press, thus making it suitable for a variety of occasions.

[0048] The electric rice and flour press 100 of this utility model includes a frame 10 with a telescopic rod 13 rotatably mounted on the base 11 of the frame 10. During use, the height and horizontal position of the pressing cylinder 33 can be flexibly adjusted as needed to meet different usage scenarios. For example, when the pressed rice flour or noodles are directly poured into the cooking pot for steaming, the telescopic rod 13 can be rotated to swing the pressing cylinder 33 outside the cooking pot when the pressing cylinder 33 is being loaded or idle, to prevent the rice or dough inside the pressing cylinder 33 from being affected by the heat from the cooking pot and causing uneven discharge. In specific operation, first, the nut is tightened, moving it away from the bolt head until the two elastic clamps 114 are loosened. At this time, the pressing cylinder 33 is subjected to force that drives the telescopic rod 13 to rotate within the sleeve 113, thereby moving the pressing cylinder 33 out or directly above the cooking pot. After the pressing cylinder 33 is moved into place, the nut is tightened again, causing the nut to move closer to the bolt head. The bolt head and the nut clamp the two elastic clamps 114, so as to firmly hold the telescopic rod 13 by means of the two elastic clamps 114, thereby preventing the telescopic rod 13 from rotating randomly under force.

[0049] The electric rice and flour press 100 of this utility model can adjust the horizontal distance between the pressing component 30 and the telescopic rod 13 by engaging the hook 311 with the slot 154 at different positions, so as to adjust the position of the pressing cylinder 33 more flexibly.

[0050] This utility model's electric rice and flour press 100 uses a high-thrust electric push rod to drive the pressing piston 35, which is more powerful and has a wider range of applications compared to household handheld noodle machines on the market. Functionally, it meets the requirements of hydraulic presses on the market, and the equipment has a compact structure, reducing the size of the equipment, lower manufacturing costs, and is simple to operate and maintain.

[0051] The above description is a detailed description of the preferred embodiments of the present utility model. However, the embodiments are not intended to limit the scope of the patent application of the present utility model. All equivalent changes or modifications made under the technical spirit of the present utility model should fall within the patent scope covered by the present utility model.
