Description

Technical Field

[0001] This utility model relates to the field of fruit wine fermentation technology, and specifically discloses a pressing device for fruit wine fermentation. Background Technology

[0002] When fermenting fruit wine, the containers used to store the fruit wine need to be pressed down. After pressing, the containers need to be left to stand for a period of time until the fruit residue separates from the fruit wine before the wine is taken out.

[0003] Chinese patent CN117511685B discloses a pressing device for fruit wine fermentation, including an outer centrifuge cylinder, an inner centrifuge cylinder, a pressing plate, a tilting door, a traction line, an adjusting box, a pressing screw, and pressing gears. This invention improves the separation of fruit wine and pomace through centrifugal operation. The suction port on the rotating box adsorbs material from the holes on the inner centrifuge cylinder, removing blockages and transferring it back into the inner centrifuge cylinder. This improves the centrifugal efficiency of the inner centrifuge cylinder without affecting the fruit wine yield. The temperature reduction at the cooling magnet promotes the sedimentation and coagulation of particles in the fruit wine, facilitating subsequent centrifugation. An additional centrifuge cylinder rotates with the inner centrifuge cylinder to further centrifuge the fruit wine, filtering out fine pomace and improving the quality of the resulting fruit wine.

[0004] The aforementioned document discloses a pressing device for fruit wine fermentation. When in use, the raw materials are pressed by intermittent filling, which results in low pressing efficiency and inconvenience in discharging fruit residue. Therefore, a pressing device for fruit wine fermentation is needed to solve this problem. Utility Model Content

[0005] This utility model proposes a pressing device for fruit wine fermentation, which realizes continuous and automated juicing and slag discharge through an eccentric rotating elastic pressing mechanism. Combined with an adjustable pressure system and modular filter plate design, it significantly improves production efficiency and facilitates maintenance.

[0006] This utility model is implemented as follows: a pressing device for fruit wine fermentation includes a cylinder, the outer wall of which is provided with a feed inlet, a slag discharge inlet and a liquid discharge inlet, the outer wall of which is provided with a pressure cap, a filter plate is detachably connected between the liquid discharge inlet and the cylinder, and a pressing mechanism is provided inside the cylinder.

[0007] The pressing mechanism includes a rotating block rotatably connected to the inside of the cylinder. A drive motor with its output end fixedly connected to the rotating block is installed on the upper end face of the cylinder. The outer wall of the rotating block is provided with multiple circumferentially distributed sliding grooves. The inner walls of the multiple sliding grooves are slidably connected with sliding plates. The interiors of the multiple sliding grooves are fixedly connected with multiple evenly distributed first springs.

[0008] As a preferred embodiment of the pressing equipment for fruit wine fermentation according to this utility model, the outer wall of the cylinder is fixedly connected to two limiting rods, the pressure cap is slidably connected to the two limiting rods, the other end of the two limiting rods is fixedly connected to a fixing plate, the outer wall of the fixing plate is threaded and threaded with a threaded rod, the end of the threaded rod near the cylinder is rotatably connected to a limiting groove, and a second spring is fixedly connected between the pressure cap and the limiting groove.

[0009] As a preferred embodiment of the pressing equipment for fruit wine fermentation according to this utility model, the outer wall of the discharge port is provided with an installation groove that matches the filter plate. The filter plate is slidably connected to the inside of the installation groove. An installation plate is fixedly connected to the upper end face of the filter plate. The installation plate is fixedly connected to the discharge port by bolts.

[0010] In a preferred embodiment of the pressing equipment for fruit wine fermentation according to this utility model, the rotating block is eccentrically positioned relative to the cylinder.

[0011] As a preferred embodiment of the pressing equipment for fruit wine fermentation according to this utility model, the end of the sliding plate near the inner wall of the cylinder is rounded.

[0013] The beneficial effects of this utility model are:

[0014] 1. Through the cooperation of an eccentrically positioned rotating block and an elastic sliding plate mechanism, the entire process of feeding, pressing, discharging, and slag removal is completed synchronously in a single drive motor cycle. During rotation, the sliding plate automatically adjusts its gap with the cylinder wall due to its eccentric structure, achieving negative pressure suction and dynamic extrusion. The wine is quickly filtered and discharged through the filter plates, while the fruit pomace is automatically unloaded through a spring-loaded capping mechanism.

[0015] 2. The screw rod-spring mechanism dynamically adjusts the pressure of the slag discharge port cap, allowing for flexible adjustment of the extrusion intensity based on raw material characteristics (such as slag hardness and moisture content), ensuring optimal juice yield and smooth slag discharge. Simultaneously, the filter plates are bolted for quick disassembly, facilitating cleaning or replacement, effectively solving filter clogging problems, extending equipment lifespan, and reducing maintenance costs.

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0022] Please see Figure 1-3 A pressing device for fruit wine fermentation includes a cylinder 1. The outer wall of the cylinder 1 is provided with a feed inlet 2, a slag discharge inlet 3 and a liquid discharge inlet 4. The outer wall of the slag discharge inlet 3 is provided with a pressure cap 12. A filter plate 16 is detachably connected between the liquid discharge inlet 4 and the cylinder 1. A pressing mechanism is provided inside the cylinder 1.

[0023] The pressing mechanism includes a rotating block 5 rotatably connected inside the cylinder 1. A drive motor 6 with its output end fixedly connected to the rotating block 5 is installed on the upper end face of the cylinder 1. Multiple circumferentially distributed sliding grooves 7 are opened on the outer wall of the rotating block 5. Slide plates 8 are slidably connected to the inner walls of the multiple sliding grooves 7. Multiple evenly distributed first springs 9 are fixedly connected inside the multiple sliding grooves 7.

[0024] In this embodiment: the drive motor 6 is started, and the drive motor 6 drives the rotating block 5 to rotate clockwise, which in turn drives multiple sliding plates 8 to rotate clockwise. Since the rotating block 5 is eccentrically set with the cylinder 1, when the rotating block 5 rotates, the sliding plates 8 slide back and forth along the sliding groove 7 under the elastic force of the first spring 9 and the squeezing action of the inner wall of the cylinder 1. When the sliding plates 8 rotate past the feed inlet 2, the gap between the rotating block 5, the sliding plates 8 and the inside of the cylinder 1 gradually increases, thereby generating negative pressure and sucking the raw material into the cylinder 1. When the sliding plates 8 rotate past the drain outlet 4, the gap between the rotating block 5, the sliding plates 8 and the inside of the cylinder 1 gradually decreases, thereby filtering the wine in the raw material through the filter plate 16 and squeezing it out from the drain outlet 4. The fruit residue continues to rotate with the sliding plates 8 and is discharged from the cylinder 1 from the residue outlet 3. This utility model can continuously perform pressing operations on the raw material, with high production efficiency, and the fruit residue can be automatically discharged from the cylinder 1, making discharge convenient.

[0025] As a technical optimization of this utility model, two limiting rods 10 are fixedly connected to the outer wall of the cylinder 1, the cover 12 is slidably connected to the two limiting rods 10, and the other end of the two limiting rods 10 is fixedly connected to a fixing plate 11. The outer wall of the fixing plate 11 is threaded through and threadedly connected to a threaded rod 13. The end of the threaded rod 13 near the cylinder 1 is rotatably connected to a limiting groove 14, and a second spring 15 is fixedly connected between the cover 12 and the limiting groove 14.

[0026] In this embodiment: as the amount of fruit residue inside the slag discharge port 3 increases, the fruit residue squeezes the pressure cap 12 to slide outward along the limiting rod 10 and compresses the second spring 15, causing the pressure cap 12 to open and thus discharge the fruit residue. Under the elastic force of the second spring 15, the pressure cap 12 is pressed tightly against the outer wall of the slag discharge port 3, which facilitates the compression of the raw materials in the cylinder 1. Rotating the threaded rod 13 causes the limiting groove 14 to move away from or closer to the pressure cap 12, thereby adjusting the pressure of the pressure cap 12 on the second spring 15, which facilitates the adjustment of the pressure on the pressure cap 12 according to the pressing effect.

[0027] As a technical optimization of this utility model, the outer wall of the drain port 4 is provided with an installation groove that matches the filter plate 16. The filter plate 16 is slidably connected to the inside of the installation groove. An installation plate 17 is fixedly connected to the upper end face of the filter plate 16. The installation plate 17 is fixedly connected to the drain port 4 by bolts.

[0028] In this embodiment, the mounting plate 17 is detachably connected to the cylinder 1 by bolts, which facilitates the disassembly, cleaning or replacement of the filter plate 16, making it convenient to use.

[0029] As a technical optimization of this utility model, the rotating block 5 is eccentrically set with respect to the cylinder 1.

[0030] In this embodiment, by setting the rotating block 5 eccentrically to the cylinder 1, the rotating block 5 can automatically complete the pressing, liquid discharge and slag discharge operations when it rotates.

[0031] As a technical optimization of this utility model, the end of the slide plate 8 near the inner wall of the cylinder 1 is rounded.

[0032] In this embodiment: by rounding the corner of the end of the slide plate 8 near the inside of the cylinder 1, it is easier for the slide plate 8 to rotate close to the inner wall of the cylinder 1.

[0033] As a technical optimization of this utility model, a controller is provided on the outer wall of the cylinder 1, and the drive motor 6 is electrically connected to the controller.

[0034] In this embodiment, the controller facilitates the normal operation of the drive motor 6.

[0035] The working principle and usage process of this utility model are as follows: When in use, the drive motor 6 is started, causing the rotating block 5 to rotate clockwise, which in turn causes multiple sliding plates 8 to rotate clockwise. Due to the eccentric arrangement of the rotating block 5 and the cylinder 1, when the rotating block 5 rotates, the sliding plates 8, under the elastic force of the first spring 9 and the squeezing action of the inner wall of the cylinder 1, slide back and forth along the sliding groove 7. When the sliding plate 8 passes the feed inlet 2, the gap between the rotating block 5, the sliding plate 8, and the inside of the cylinder 1 gradually increases, thereby generating negative pressure and drawing the raw material into the cylinder 1. When the sliding plate 8 passes the drain outlet 4, the gap between the rotating block 5, the sliding plate 8, and the inside of the cylinder 1 gradually decreases, from... The wine in the raw material is filtered through the filter plate 16 and squeezed out from the discharge port 4. The fruit pomace continues to rotate with the slide plate 8 and enters the pomace discharge port 3. As the pomace inside the discharge port 3 increases, it squeezes the pressure cap 12 to slide outward along the limiting rod 10 and compresses the second spring 15, causing the pressure cap 12 to open and discharge the fruit pomace. Under the elastic force of the second spring 15, the pressure cap 12 is pressed tightly against the outer wall of the discharge port 3, which facilitates the compression of the raw material in the cylinder 1. Rotating the threaded rod 13 causes the limiting groove 14 to move away from or closer to the pressure cap 12, thereby adjusting the pressure on the pressure cap 12 under the second spring 15. This allows for adjustment of the pressure on the pressure cap 12 according to the pressing effect. This utility model can continuously press the raw material, resulting in high production efficiency, and the fruit pomace can be automatically discharged from the cylinder 1, making discharge convenient.
