Description

Technical Field

[0001] The utility model relates to the technical field of food processing, and specifically relates to a filter press device for food processing with a filtrate diversion mechanism. Background Art

[0002] In food processing, a large amount of solid-liquid mixtures are often generated, such as starch slurry, fruit juice residue, etc. Traditional separation methods are inefficient and time-consuming. The filter press device, with its high-efficiency solid-liquid separation ability, has become a key device for improving production efficiency.

[0003] For example, a food additive filter press disclosed in Chinese Patent Publication No. CN118526841A. In this existing device, by setting a first hydraulic cylinder, it can drive five groups of frames to approach each other, so that the first fixing plate connected by the first connecting rod squeezes the spring in the connecting sleeve. At the same time, the second fixing plate connected by the fourth connecting rod moves in the movable sleeve, and the food additive in the cavity of the frame is squeezed by the pressing plate, so that the liquid in the food additive is discharged through the liquid outlets on both sides of the frame. However, in actual application, this existing device only relies on the natural drainage of the liquid outlets on both sides of the frame and lacks an active diversion mechanism, resulting in a relatively high residual amount of filtrate in the frame, requiring frequent shutdown for cleaning, which affects the continuous production efficiency. Moreover, only one-way extrusion can be achieved in this existing device, and for block-shaped or irregularly shaped food raw materials, uneven local stress is likely to occur, resulting in incomplete extraction of the filtrate. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a filter press device for food processing with a filtrate diversion mechanism. The upper pressing plate is driven to press down by a screw rod, and the side pressing plates are synchronously pressed inward through a bevel gear transmission chain to form a three-dimensional extrusion structure, which can apply uniform pressure to different parts of the food, effectively destroy the cell structure, and promote more liquid to be extruded.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A filter press device for food processing with a filtrate diversion mechanism, including a support base. A connection frame is arranged at the top of the support base, an installation housing is arranged at the top of the connection frame, a processing frame for storing food is arranged in the installation housing, a feed hopper is arranged beside the installation housing, an inclined guide plate is arranged in the feed hopper, a support frame is arranged at the bottom of the feed hopper, an adjustment filter press mechanism for filtering the food in the processing frame is arranged in the installation housing, and a material taking door for facilitating the taking out of the food in the processing frame is arranged in the installation housing.

[0006] The adjustment filter press mechanism includes a first filter press component and a second filter press component. The first filter press component includes a guide rod arranged in the installation housing, a connecting plate is slidably arranged outside the guide rod, and an upper pressing plate for pressing the food is arranged at the bottom of the connecting plate.

[0007] The second filter press assembly includes two side pressing plates slidably arranged in the processing frame for pressing food.

[0008] The connection frame is provided with a filtrate guiding component for guiding the squeezed filtrate. The filtrate guiding component comprises a conical guide plate provided in the connection frame and a liquid guiding frame provided outside the connection frame.

[0009] Preferably, the first filter press assembly includes a first motor arranged at the top of the mounting shell, and the output shaft of the first motor is transmission-connected with a screw rod, which passes through one end of the connecting plate away from the guide rod and is threadedly connected to the connecting plate.

[0010] Preferably, the second filter press assembly includes a connecting rod rotating in the processing frame, and bevel gears are provided outside the connecting rod and the screw, and the two bevel gears are meshed with each other.

[0011] Preferably, rack plates are provided outside the two side pressure plates, and the rack plates are slidably arranged in the processing frame.

[0012] Preferably, the second filter press assembly further comprises a connecting gear disposed outside the connecting rod, and the connecting gear is meshed with both rack plates.

[0016] Compared with the prior art, the present invention provides a filter press device for food processing with a filtrate diversion mechanism, which has the following beneficial effects:

[0017] 1. This food processing filter press, equipped with a filtrate diversion mechanism, features an upper pressure plate driven downward by a screw, while the side pressure plates simultaneously press inward via a bevel gear transmission chain, forming a three-dimensional extrusion structure. This design applies uniform pressure to different parts of the food, effectively disrupting the cell structure and allowing more liquid to be squeezed out. The extruded filtrate is then directed through the filter plates and concentratedly channeled to the spiral conveyor mechanism via a conical guide plate, preventing filtrate residue. The rotation of the spiral conveyor shaft further ensures complete filtrate discharge, reducing resource waste.

[0018] 2. After the extrusion is completed, the first motor rotates in the reverse direction, and the upper pressing plate and the side pressing plates can be synchronously reset through the bevel gear transmission chain without manual intervention, shortening the idling time of the equipment. After the reset, the feeding door can be opened to take out the processed food residues without additional complex operations, improving the production continuity. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0028] Example 1: Please refer to Figures 1 - 7 The utility model provides a technical solution: a filter press device for food processing with a filtrate diversion mechanism, comprising a support base 1, a connecting frame 2 is provided at the top of the support base 1, a mounting shell 3 is provided at the top of the connecting frame 2, a processing frame 31 for storing food is provided in the mounting shell 3, a feed hopper 4 is provided on the side of the mounting shell 3, an inclined guide plate 41 is provided in the feed hopper 4, a support frame 42 is provided at the bottom end of the feed hopper 4, an adjusting filter press mechanism 5 for filtering the food in the processing frame 31 is provided in the mounting shell 3, and a material removal door 32 for conveniently removing the food from the processing frame 31 is provided in the mounting shell 3. The support base 1, the connecting frame 2, and the mounting shell 3 are arranged in layers for easy maintenance and expansion. The design of the material removal door 32 simplifies the process of removing food residues, reduces manual intervention, and improves operating efficiency.

[0029] The adjustable filter press mechanism 5 comprises a first filter press assembly 51 and a second filter press assembly 52. The first filter press assembly 51 comprises a guide rod 511 mounted within the mounting housing 3. A connecting plate 512 is slidably mounted on the outside of the guide rod 511. The bottom end of the connecting plate 512 is provided with an upper pressure plate 513 for pressing the food. The connecting plate 512 is ensured to move vertically to avoid deviation and uneven filtration. The design of the upper pressure plate 513 allows pressure to directly act on the food surface, achieving initial squeezing and improving the initial separation efficiency of the filtrate.

[0030] The second filter press assembly 52 includes two side pressing plates 521 slidably disposed in the processing frame 31 for pressing the food. The food is pressed from the side, forming a three-dimensional pressing with the upper pressing plate 513, which significantly improves the filtrate recovery rate.

[0031] Furthermore, the first filter press assembly 51 includes a first motor 514 mounted at the top of the mounting housing 3. A screw 515 is drivingly connected to the output shaft of the first motor 514. The screw 515 extends through the end of the connecting plate 512 away from the guide rod and is threadedly connected to the connecting plate 512. This threaded drive enables precise downward pressure on the upper pressure plate 513, adapting to the filter pressing requirements of different foods.

[0032] Furthermore, the second filter press assembly 52 includes a connecting rod 522 that rotates within the processing frame 31. Bevel gears 523 are disposed on the outside of the connecting rod 522 and the screw 515, and the two bevel gears 523 are meshed. The power of the screw 515 synchronously drives the side pressure plates 521, ensuring that the upper pressure plate 513 and the side pressure plates 521 work in coordination, improving the consistency of the filter press, reducing the need for additional power sources, and lowering energy consumption.

[0033] Furthermore, rack plates 525 are provided outside both side pressing plates 521. The rack plates 525 are slidably arranged in the processing frame 31. The rotary motion is converted into linear motion to achieve the stable movement of the side pressing plates 521.

[0034] Furthermore, the second pressure filtration assembly 52 includes a connecting gear 524 arranged outside the connecting rod 522. The connecting gear 524 meshes with both rack plates 525. Ensure that the two side pressing plates 521 are synchronously centered and extruded to avoid leakage of filtrate caused by deviation.

[0035] Furthermore, a filter plate 526 is arranged at the inner bottom end of the processing frame 31. The design of the filter plate 526 can filter food residues, ensure the leakage of filtrate, and reduce the subsequent processing cost.

[0036] Embodiment 2: Please refer to Figure 7 , and in combination with Embodiment 1, it is further obtained that a filtrate diversion assembly 6 for diverting the extruded filtrate is arranged in the connecting frame 2. The filtrate diversion assembly 6 includes a conical guide plate 61 arranged in the connecting frame 2 and a liquid guide frame 62 arranged outside the connecting frame 2. A spiral conveyor shaft 63 is rotatably arranged in the connecting frame 2, and the spiral conveyor shaft 63 is located at the bottom end of the conical guide plate 61. The diversion of the conical guide plate 61 can concentrate the flow direction of the filtrate, avoid residue, and improve the filtrate recovery rate. Moreover, the transmission of the spiral conveyor shaft 63 can forcibly convey the filtrate, prevent blockage, and ensure continuous production.

[0037] Furthermore, the filtrate diversion assembly 6 further includes a mounting seat 64 arranged outside the connecting frame 2. A second motor 65 is fixed in the mounting seat 64. The output shaft of the second motor 65 is in transmission connection with the spiral conveyor shaft 63. The filtrate transmission can be independently controlled to adapt to different filtrate flow requirements.

[0038] In the actual operation process, first, the food to be filter-pressed is put into the feeding hopper 4 and introduced into the processing frame 31 through the inclined guide plate 41. Subsequently, the first motor 514 is started to drive the screw 515 to rotate. Under the limitation of the guide rod 511, the connecting plate 512 moves axially along the screw 515, driving the upper pressing plate 513 to press down the food and squeeze out the liquid. When the screw 515 rotates, the connecting rod 522 is driven to rotate synchronously through the bevel gear 523 transmission chain. The connecting gear 524 drives the two rack plates 525 to slide centrally, causing the side pressing plates 521 to squeeze the food inward, forming a synergistic effect with the upper pressing plate 513, and the filtrate is led out from the filter plate 526. Moreover, leakage strip holes are added in the processing frame 31, and the leakage strip holes are internally communicated with the two rack plates 525, so that the liquid flowing into the interiors of the two rack plates 525 can be led out. The led-out filtrate is guided to the connecting frame 2 under the action of the conical guide plate 61 in the connecting frame 2. The second motor 65 is started to drive the spiral conveyor shaft 63 to rotate, and the filtrate is conveyed through the liquid guide frame 62 to the outside of the connecting frame 2 for unified treatment. After the extrusion is completed, the first motor 514 is driven in the reverse direction, and the upper pressing plate 513 and the side pressing plates 521 are reset through the bevel gear transmission chain to relieve the extrusion of the food. The feeding door 32 is opened, and the food residue in the processing frame 31 is taken out.

[0039] The above embodiments only represent one or several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
