Description

Technical Field

[0001] This utility model relates to a device for processing leftover food, and more particularly to a device for pre-processing leftover food from the dining table. Background Technology

[0002] Office buildings of enterprises and institutions, schools, hospitals, hotels, and health and wellness centers often have centralized dining areas such as restaurants and canteens, which frequently generate large amounts of leftover food. This leftover food typically includes meat and vegetables rich in organic matter, animal and vegetable oils, and water. To effectively utilize these leftover foods, they can be processed into organic fertilizer or animal feed. However, because leftover food contains a large amount of residual animal and vegetable oils, failure to remove this oily water will significantly affect the quality of the organic fertilizer or animal feed, negatively impacting the land used for fertilization or the animals fed with it. Therefore, most existing methods for processing leftover food require the removal of the oily water.

[0003] Currently, leftover food is typically placed on equipment with a sieve to remove oil and water. However, oil and water pass through the sieve mesh slowly, often adhering to the mesh and even clogging it. This significantly reduces the efficiency of oil and water passage, increases the time and cost of replacing and repairing the sieve, and lowers the overall efficiency of leftover food processing. Utility Model Content

[0004] The purpose of this invention is to solve the above-mentioned problems and provide a device for pre-processing leftover food on the dining table.

[0005] To achieve the above-mentioned objectives of this utility model, the pretreatment device for leftover food provided by this utility model includes a box body, wherein a separation chamber is provided on the upper side of one side of the box body for separating the oil and water in the collected leftover food from the food; the remaining part of the box body is a water storage chamber connected to the separation chamber for storing the oil and water separated by the separation chamber; wherein the separation chamber has an oil and water separation plate with oil and water holes for allowing the oil and water in the leftover food to flow through quickly.

[0006] Preferably, the oil-water separator plate is provided with multiple rows of elongated oil-water passage holes, each row of oil-water passage holes includes multiple oil-water passage holes, and the multiple oil-water passage holes in two adjacent rows are staggered or correspondingly arranged.

[0014] Preferably, it also includes a water spraying device for supplying water to the separation chamber to accelerate the separation of oil and water from leftover food on the table.

[0015] Compared with the prior art, the beneficial effects of this utility model are reflected in the following aspects:

[0016] 1. This utility model is a pre-treatment device for leftover food at the dining table. It can effectively separate the oil and water in leftover food at the dining table and the separation speed is fast, which reduces the cost of leftover food treatment and improves the treatment efficiency.

[0029] like Figure 1 , Figure 8 , Figure 10 , Figure 11 The figures show four different structural diagrams of the food waste pretreatment device provided by this utility model. As can be seen from the figures, the food waste pretreatment device 100 of this utility model includes a box body 1. A separation chamber 2 is provided on the upper side of one side of the box body for separating the oil and water in the collected food waste from the food. The remaining part of the box body is a water storage chamber 6 connected to the separation chamber for storing the oil and water separated by the separation chamber. The separation chamber has an oil and water separation plate 3 with oil and water holes for allowing the oil and water in the food waste to flow through quickly.

[0030] In addition to the structure described above, the pretreatment device for leftover food at the dining table of this utility model may also include a crushing device and / or a water supply device. The structure of the pretreatment device for leftover food at the dining table of this utility model will be described in detail below.

[0031] Example 1

[0032] like Figures 1-3 As shown, the food waste pretreatment device in this embodiment includes a box 1. A separation chamber 2 is provided on the upper side of one side of the box for separating the oil and water in the collected food waste from the food. The rest of the box is a water storage chamber 6 connected to the separation chamber for storing the oil and water separated by the separation chamber. The separation chamber has an oil and water separation plate 3 with oil and water holes for allowing the oil and water in the food waste to flow through quickly.

[0033] Specifically, in this embodiment, the container is rectangular in shape. One side of the upper part is partitioned off as a separation chamber to separate the oily water from the collected leftover food. Below and beside the separation chamber is a water storage chamber 6 for receiving the oily water. A cover 4, detachably connected to the top of the container (the connection method can use existing technology, which will not be detailed here), is installed at the opening of the water storage chamber next to the separation chamber. A drain pipe 5 is installed at the bottom of the water storage chamber to discharge the oily water flowing out of the separation chamber. The drain pipe is designed with a manual valve; opening the valve allows the oily water to flow out automatically. The drain pipe can be directly or indirectly connected to the kitchen sewage pipe, facilitating the recycling or subsequent treatment of the oily water.

[0034] The bottom plate of the separation chamber is a rectangular oil-water separation plate with oil-water passage holes. Three sides are fixedly connected to the three inner walls of the box, and one side is fixedly supported by a support frame fixed to the inner wall of the box. When in use, the collected leftover food from the table can be poured into the separation chamber. The oil and water in the leftover food can pass through the oil-water passage holes 32 of the oil-water separation plate and fall into the water storage chamber located below the separation chamber of the box.

[0035] To prevent the oil and water content in leftover food from passing through the oil-water separator plate too slowly, as is common in existing technologies where surface tension causes slow passage through circular oil-water holes, this embodiment uses an oil-water separator plate as follows: Figure 4 , Figure 5 The first structure shown is that the oil-water separator plate is a flat plate 31, on which multiple rows of elongated oil-water passage holes 32 are provided. Each row of oil-water passage holes includes multiple oil-water passage holes, and the multiple oil-water passage holes in adjacent rows are staggered (see...). Figure 4 (or corresponding settings, not shown in the figure). Furthermore, to accelerate the passage of oil and water from leftover food through the oil-water separator's holes, the elongated oil-water holes in this embodiment have a frustum-shaped cross-section, with the top narrow and the bottom wide (e.g., ...). Figure 5 (As shown).

[0036] Alternatively, the oil-water separator in this embodiment can also be as follows: Figure 6 , Figure 7The second structure shown includes an oil-water separator plate comprising multiple parallel, elongated screen plates 33, with oil-water passage holes 32 formed between adjacent screen plates for the flow of oil-containing water. Furthermore, the screen plates have a frustum-shaped cross-section, wider at the top and narrower at the bottom, resulting in oil-water passage holes between adjacent screen plates that are narrower at the top and wider at the bottom. During manufacturing, multiple screen plates are arranged in parallel and welded to a frame at their ends, with one or more stiffening plates supporting the bottom. The frame is then welded to the inner wall of the housing. The screen plates are made of non-magnetic, wear-resistant, high-quality stainless steel, with a scratch-free surface and a smooth, undistorted finish after welding. The stiffening plates supporting the bottom of the screen plates must not extend beyond the lower edge of the oil-water separator plate.

[0037] Regardless of which structure the oil-water separator plate adopts, the upper width of the frustum-shaped oil-water passage is 0.8-1.2 mm, preferably 1 mm, the cone angle is 11-15 degrees, preferably 13 degrees, and the spacing between adjacent oil-water passages is 1.5-2.5 mm, preferably 2 mm.

[0038] In this embodiment, the oil-water separator plate uses a frustoconical hole that is narrow at the top and wide at the bottom. This significantly accelerates the flow of oil and water from leftover food through the oil-water separator plate's holes, greatly improving the efficiency of separating oil and water from food, thus increasing the processing efficiency of leftover food. This embodiment also utilizes gravity to allow the oil and water in leftover food to naturally separate from the food, resulting in energy saving, emission reduction, and environmental protection.

[0039] The following is a brief description of the process by which the food waste pretreatment device in this embodiment processes the collected food waste:

[0040] Pour the leftover food from the table into the separation chamber and spread it evenly on the oil-water separation plate. Under the action of gravity, the oil and water from the leftover food will flow through the oil passages of the oil-water separation plate and flow downwards into the water storage chamber. When the oil and water in the water storage chamber reaches the predetermined height, open the valve to allow the oil and water to flow out automatically from the drain pipe.

[0041] Example 2

[0042] Sometimes leftover food contains a lot of long fibers. Because oil is viscous, a large amount of oil and water will adhere to the food containing these fibers. If such leftover food is placed directly in the separation chamber, the oil and water will have difficulty separating from the food and will not be able to pass through the oil-water separation plate's drainage holes. To solve this problem, such as... Figure 8 As shown, the table leftover food pretreatment device in this embodiment, based on the structure of Embodiment 1, also includes a crushing device 200 located on the side of the box. The crushing device crushes the long fiber material in the table leftover food containing long fibers, and the crushed material is transported to the separation chamber through a downwardly inclined conveying pipe 300.

[0043] In this embodiment, the crushing device 200 can be adopted as follows: Figure 9 The structure shown includes a frame, within which a crushing mechanism is provided. The crushing mechanism has a feed inlet 221 located at the upper part of one end and a discharge outlet 222 located at the lower part of the other end. At least one set of crushing and conveying blades is provided between the feed inlet 221 and the discharge outlet 222 to crush and process leftover food containing long fibers, thereby moving the crushed material from the feed inlet to the discharge outlet. The discharge outlet is fixedly connected to one end of a conveying pipe.

[0044] Specifically, the crushing mechanism adopts, for example... Figure 9 The structure shown includes a crushing and conveying cylinder 202 and a crushing and conveying mechanism 203 housed within the crushing and conveying cylinder 202. The crushing and conveying cylinder is horizontally mounted on the frame, with its axis parallel to the ground. One end of the crushing and conveying cylinder has an upper feed inlet, and the other end has a lower discharge outlet. A pusher is located on the upper part of the frame, and a guide plate at a certain angle to the horizontal plane is installed between the pusher and the feed inlet to facilitate feeding. Leftover food containing long fibers is fed into the feed inlet through the pusher along the guide plate and then into the crushing and conveying cylinder. After being gradually crushed by the crushing and conveying mechanism, it is pushed to the discharge outlet and then conveyed into the separation chamber via a conveying pipe.

[0045] like Figure 9 As shown, the crushing and conveying mechanism includes a rotating shaft 232 and at least one set of crushing and conveying cutters mounted along the rotating shaft 232. The two ends of the rotating shaft are rotatably supported within the crushing and conveying cylinder by bearings, and are driven to rotate by a drive mechanism 204 mounted within the frame. The drive mechanism includes: a pair of pulleys 241 respectively connected to the rotating shaft and the motor shaft; a belt connecting the pair of pulleys; and a motor 242 driving the pair of pulleys to rotate. When the motor rotates, it drives the rotating shaft to rotate via the pair of pulleys, thereby driving the crushing and conveying cutters to rotate, in order to crush long-fiber materials in leftover food.

[0046] At least one set of crushing and conveying cutters is alternately arranged along the axial and circumferential directions on a rotating shaft. Each set of crushing and conveying cutters includes at least three crushing blades. Several crushing blades are sequentially mounted and fixed on the rotating shaft, and their installation orientation is changed sequentially along the circumferential direction of the rotating shaft so as to form a spiral channel that allows the material to move forward along a spiral trajectory when the crushing blades rotate. When the drive mechanism drives the rotating shaft to rotate via a pulley, the rotating shaft drives these crushing blades to rotate, gradually crushing the long-fiber leftover food received from the feed inlet while pushing it to the discharge outlet.

[0047] The crushing and conveying cutter in this embodiment can adopt the structure of existing technology, which will not be described in detail here.

[0048] During the design phase, the discharge port of the crushing device is positioned a certain distance above the upper surface of the housing, allowing the inclined conveying pipe to smoothly deliver the crushed material from the discharge port into the separation chamber, where it is effectively separated from the oil by the oil-water separation plate. In practical application, the decision to use a crushing device depends on the amount of long-fiber material present in the leftover food.

[0049] When the food waste pretreatment device has a crushing device, the process of processing the collected food waste is basically the same as described above. The difference is that before spreading the food waste on the oil-water separation plate, the food waste containing long fibers is first poured into the feed inlet of the crushing device. The crushing mechanism crushes it into crushed material of about 1cm. Then, the crushed material is sent into the separation chamber through the conveying pipe and then spread on the oil-water separation plate.

[0050] Example 3

[0051] To address the issue that oil and water may solidify or adhere to leftover food due to prolonged storage and / or low temperature, making it difficult for the collected food waste to flow through the oil drain holes, this embodiment of the food waste pretreatment device, based on the above embodiment, can also include a hot water spray device 400 on the side of the casing. The pipe of the spray device can extend above the separation chamber (e.g., Figure 10 , Figure 11 As shown in the diagram, a water nozzle with an adjustable spray direction is installed at the end of the pipe. Hot water at a certain temperature (e.g., 20 to 50°C) is supplied to the separation chamber via a spray device, which accelerates the separation of oil and water from leftover food, ensuring thorough separation. The water nozzle can be designed similarly to a showerhead, allowing for adjustment of the spray direction towards the leftover food as needed.

[0052] When the food waste pretreatment device has a water spraying device, the process of processing the collected food waste is basically the same as described above. The difference is that after spreading the food waste on the oil-water separation plate, hot water is sprayed onto the food waste through the water spraying device to fully melt the grease on the food waste, so that the oil and water can quickly separate from the food waste and flow through the oil passage of the oil-water separation plate under the action of gravity, and flow downward into the water storage chamber.

[0053] In summary, this utility model of a pre-treatment device for leftover food can quickly separate the oil and water content from the collected leftover food, making the treated leftover food more suitable for the production of organic fertilizer or animal feed. It also features a simple structure, energy saving, emission reduction, and environmental protection.

[0054] Although the present invention has been described in detail above, it is not limited thereto. Those skilled in the art can make modifications based on the principles of the present invention. Therefore, all modifications made in accordance with the principles of the present invention should be understood as falling within the protection scope of the present invention.
