Description

Technical Field

[0001] This utility model relates to a device for processing leftover food, and more particularly to a device for squeezing and processing leftover food from the kitchen. 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 the 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 and often adhere to the mesh, sometimes 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 ultimately reduces the efficiency of leftover food processing. Utility Model Content

[0004] The purpose of this invention is to solve the above problems by providing a kitchen waste food compression processing device. It has a simple structure, is easy to use, consumes little energy, is clean and environmentally friendly, and can effectively separate oil and water from leftover food at a fast speed, thereby reducing the cost of leftover food processing, equipment purchase and maintenance costs, and improving the efficiency of leftover food processing.

[0005] To achieve the above-mentioned objectives of this utility model, the kitchen waste food compression processing device provided by this utility model includes a box body, and further includes: a primary separation structure disposed in the box body for naturally separating the collected leftover food from the oil and water; a secondary separation structure disposed on the box body and located on one side of the primary separation structure for further separating the semi-finished product after processing by the primary separation structure from the oil and water; a residue receiving structure disposed on one side of the box body for receiving the food residue obtained after processing by the secondary separation structure; and a drain pipe or drain hole disposed on the box body for discharging the oil and water obtained after processing by the primary and secondary separation structures.

[0006] Preferably, the primary separation structure includes an oil-water permeable plate with oil-water perforations disposed within the box body for rapidly allowing oily and watery contents from leftover food on the table to flow through.

[0007] Preferably, the oil-water permeable plate is provided with multiple rows of elongated oil-water perforations, each row of oil-water perforations includes multiple oil-water perforations, and the multiple oil-water perforations in two adjacent rows are staggered or correspondingly arranged.

[0008] Alternatively, the oil-water permeable plate includes multiple parallel sieve plates, with oil-water perforations formed between adjacent sieve plates for allowing oil-containing water to flow down.

[0009] Preferably, the cross-section of the oil-water passage is frustoconical.

[0010] Preferably, the re-separation structure includes a helical blade structure and a drive structure for driving its rotation.

[0011] Preferably, the re-separation structure further includes a permeable plate with permeable holes disposed within the housing and located below the helical blade structure.

[0012] Preferably, the height of the oil-water permeable plate inside the housing is greater than the height of the spiral shaft of the spiral blade structure.

[0013] Preferably, it also includes a water spraying device for supplying water to the primary separation structure to accelerate the separation of oil and water from leftover food.

[0014] Preferably, it also includes a crushing device for crushing and processing leftover food containing long fibers, the material outlet of which is connected to the primary separation structure.

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

[0016] 1. This utility model of kitchen waste food squeezing and processing device has a simple structure, is easy to use, consumes little energy, is clean and environmentally friendly, can fully separate oil and water and grease from wastewater in leftover food, and the separation speed is fast, reducing the cost of leftover food processing and improving processing efficiency.

[0017] 2. The kitchen waste food compression processing device of this utility model performs two separation processes on the collected kitchen waste food through a primary separation structure and a secondary separation structure. The separation of oil and water from food is fast, efficient, and effective, resulting in extremely low oil and water content in the food residue after separation. This makes it easy to process the food residue into organic fertilizer or animal feed. Attached Figure Description

[0032] like Figures 1-3The diagram shows different structural schematics of the food waste squeezing and processing device provided by this utility model when using the first structure. As shown in the diagram, the food waste squeezing and processing device 100 of this utility model includes a box body 1, and further includes: a primary separation structure disposed in the box body for naturally separating the collected food waste from the oil and water; a secondary separation structure disposed on the box body and located on one side of the primary separation structure for further separating the semi-finished product after the separation structure from the oil and water; a residue receiving structure disposed on one side of the box body for receiving the food residue obtained after the secondary separation structure; and a drain pipe or drain hole disposed on the box body for discharging the oil and water obtained after the primary and secondary separation structures.

[0033] Specifically, such as Figures 1-3 As shown, the box of this utility model is rectangular, and one side of its front and rear direction (such as...) Figure 3 The upper side) is the initial separation structure that can initially separate the oil and water content from the collected leftover food from the food itself; the other side (such as...) Figure 3 The lower side of the box is a secondary separation structure for further separating the oil, water, and food from the semi-finished product that has already undergone the initial separation process. One side of the box (e.g., the left-right side) Figure 1 , Figure 3 The first cover is set on the left side, and the other side (such as...) Figure 1 , Figure 3 A second cover is set on the right side.

[0034] Among them, such as Figure 3 , Figure 10 , Figure 11 As shown, the initial separation structure includes an oil-water permeable plate 4 with oil-water perforations. The oil-water permeable plate is rectangular, with three sides fixedly connected to the upper middle part of the inner wall of the three side panels of the box, and one side fixedly supported by a support frame fixed to the inner wall of the box. There is a certain distance between the lower surface of the oil-water permeable plate and the bottom plate of the box to form a cavity. An independent space is separated in the upper part of one side of the box by the oil-water permeable plate. This independent space is used to hold the collected leftover food from the table, and the oil and water in the leftover food from the table passes through the oil-water perforations on the oil-water permeable plate and falls into the cavity located below.

[0035] To prevent the oil and water content in leftover food from passing through the oil-water permeable plate from being slowed down due to surface tension, as is common in existing technologies where oil and water flow through circular oil-water permeable holes, this invention's oil-water permeable plate can employ the following... Figure 6 , Figure 7The first structure shown is a flat plate 41 with multiple rows of elongated oil-water passage holes 42. 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 6 (or corresponding settings, not shown in the figure). Furthermore, to accelerate the passage of oil and water from leftover food through the oil-water permeable plate's holes, the cross-section of the elongated oil-water permeable hole in this invention is frustoconical, with the frustoconical hole being narrower at the top and wider at the bottom (e.g., ...). Figure 7 (As shown).

[0036] Alternatively, the oil-permeable water-permeable plate of this utility model can also be used as follows: Figure 8 , Figure 9 The second structure shown, namely, the oil-water permeable plate includes multiple parallel, elongated screen plates 43, with oil-water passage holes 42 formed between adjacent screen plates for allowing oil-containing water to flow down. Furthermore, the screen plates have a frustum-shaped cross-section, and the frustum-shaped screen plates are wider at the top and narrower at the bottom (e.g., ...). Figure 9 As shown in the diagram, this creates a frustum-shaped hole between adjacent screen plates, narrow at the top and wide at the bottom. During manufacturing, multiple screen plates can be arranged in parallel with their ends welded to a frame, supported at the bottom by one or more stiffening plates. 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 permeable plate.

[0037] Regardless of which structure the oil-water permeable 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] This utility model's oil-water permeable plate, with its conical holes narrow at the top and wide at the bottom, significantly accelerates the flow of oil and water from leftover food through the permeable holes, greatly improving the efficiency of oil-water separation from food and thus increasing the processing efficiency of leftover food. After the leftover food is poured onto the oil-water permeable plate and spread evenly, gravity causes the oil and water to flow through the permeable holes and downwards into the water storage chamber. Therefore, this utility model utilizes gravity to naturally separate the oil and water from the leftover food, resulting in energy saving, emission reduction, and environmental protection.

[0039] After the initial separation structure performs the first oil-water separation process on the leftover food from the table, the secondary separation structure performs a second oil-water separation process on the semi-finished leftover food from the table after the initial separation process.

[0040] The secondary separation structure is located on one side of the primary separation structure and includes a helical blade structure 5, a drive structure 2 for rotating the helical blade structure, and a permeable plate 6 with drainage holes, disposed within the housing and located below the helical blade structure. The helical blade structure and drive structure can be, for example, […]. Figure 1 , Figures 3-5 The arrangement shown is such that the two ends of the spiral shaft of the spiral blade structure pass through the side plates on the left and right sides of the housing and extend outwards. The two ends of the spiral shaft are rotatably connected to the side plates. One end extending outside the left side of the housing is connected to the drive structure and is protected by the first cover together with the drive structure. The other end extending outside the right side of the housing is protected by the second cover. The drive structure includes a motor 21 and a transmission mechanism 22 connected to the motor output shaft and the spiral shaft respectively. This transmission mechanism can be a belt drive mechanism, a gear drive mechanism, or other transmission mechanisms, which transmits the power output of the motor to the spiral shaft, causing the spiral shaft to rotate.

[0041] The spiral blade structure has multiple spiral blades arranged along the spiral axis, and the spacing between the multiple spiral blades gradually decreases from the end closer to the drive structure to the end farther away from the drive structure. The multiple spiral blades with varying spacing can squeeze the semi-finished food left on the table that has slid down from the oil-water permeable plate after the initial separation process. During the squeezing process, the oil and water are fully separated from the food, and the separated oil and water seeps into the cavity below through the permeable plate located below the spiral blade structure.

[0042] like Figure 3 , Figure 10 , Figure 11 As shown, the permeation plate is also rectangular, with three sides fixedly connected to the lower middle part of the inner walls of the three side panels of the box, and one side fixedly supported by a support frame fixed to the inner wall of the box, or fixedly connected to the oil-water permeable plate of the initial separation structure through a vertical plate. A certain distance exists between the lower surface of the permeation plate and the bottom plate of the box, forming another cavity. This permeation plate separates an independent space on one side of the box, which is used to house the spiral blade structure and the semi-finished food leftovers from the table after the initial separation process, which slides down from the oil-water permeable plate. After the spiral blade structure squeezes and separates the oil and water in the semi-finished product, the oil and water separated from the food will fall into the cavity below through the permeation holes on the permeation plate.

[0043] In order to accelerate the speed at which oil and water in the semi-finished food leftovers pass through the permeation holes of the permeation plate, the permeation plate of this utility model can adopt the structure of the existing screen or the same structure as the above-mentioned oil and water permeation plate, which will not be described in detail here.

[0044] During assembly, such as Figure 10 , Figure 11As shown, the height of the oil-permeable plate 4 inside the housing is greater than the height of the spiral shaft of the spiral blade structure, while the height of the water-permeable plate is lower than the height of the lowest point of the spiral blade in the spiral blade structure. The spiral blade structure can be installed horizontally inside the housing (not shown in the figure), and correspondingly, the oil-permeable plate and the water-permeable plate can be installed horizontally inside the housing. Alternatively, the spiral blade structure can be installed inclined upwards from left to right inside the housing (e.g., ...). Figure 1 , Figure 10 As shown in the diagram, the oil-water permeable plate and the water-permeable plate are also installed at an angle inside the box. Of course, the oil-water permeable plate and the water-permeable plate can also be installed horizontally inside the box. In addition, in order to facilitate the natural sliding of the semi-finished food leftovers after the initial separation process to the spiral blade structure, the oil-water permeable plate can also be tilted downwards from the inside of the box away from the spiral blade structure towards the spiral blade structure (as shown in the diagram). Figure 12 (As shown).

[0045] The system employs two separation structures to separate the oil and water in leftover food from the dining table. The oily water falls into a cavity located inside the chamber below the oil-water permeable plate and the water-permeable plate. To drain the oily water, a drain hole or drain pipe can be installed on either side panel of the chamber, allowing it to be discharged for further processing. The food residue, after being extruded by the spiral blade structure, is conveyed by the spiral blade structure to a second protective cover located on the right side of the chamber. During operation, a discharge port is located below the second protective cover, and a residue collection structure (not shown in the figure) is installed below the discharge port to collect the discharged food residue. This residue has been thoroughly de-oiled, facilitating subsequent processing. The residue collection structure can be a container or a pipe.

[0046] To prevent the collected food waste from solidifying or adhering excessively to the food waste due to prolonged storage and / or low temperature, thus hindering the flow of oil through the oil-water separation plate, this utility model's food waste squeezing and processing device, based on the aforementioned structure, also includes a hot water spray device 400 installed on the side of the casing. The pipe of the spray device can extend above the oil-water separation chamber (e.g., ...). Figure 12 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 oil-water 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.

[0047] When the food waste squeezing and processing device is equipped with a water spraying device, the collected food waste is first poured into and spread evenly on the oil-water permeable plate. Hot water is then sprayed onto the food waste through the water spraying device to fully melt the grease on the food waste. Under the action of gravity, the oil and water in the food waste flows through the oil holes of the oil-water permeable plate and flows downward into the box. The food semi-finished product that has initially separated from the oil and water falls into the spiral blade structure by manual stirring or natural sliding. Through the squeezing process of the spiral blade structure, the oil and water in the food semi-finished product are fully separated from the food.

[0048] Sometimes leftover food contains a lot of long fibers. Because grease is viscous, oil and water tend to adhere to this fiber-rich food. If such leftovers are placed directly on an oil-water permeable plate, the oil and water will have difficulty separating from the food and flowing through the permeable holes. To solve this problem, such as... Figure 13 As shown, the kitchen waste food compression processing device of this utility model also includes a crushing device 200 set on the side of the box. The crushing device crushes the long fiber material in the kitchen waste food containing long fibers, and the crushed material is transported to the separation chamber through the downward inclined conveying pipe 300.

[0049] In this embodiment, the crushing device 200 can be adopted as follows: Figure 14 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.

[0050] Specifically, the crushing mechanism 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, meaning its axis is parallel to the ground. One end of the crushing and conveying cylinder has a feed inlet at the top, and the other end has a discharge outlet at the bottom. 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.

[0051] 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.

[0052] 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.

[0053] The crushing and conveying cutter in this embodiment can adopt the structure of existing technology, which will not be described in detail here.

[0054] 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 feed the crushed material from the discharge port onto the oil-water permeable plate, where it can be effectively de-oiled. In practical application, the decision to use a crushing device depends on the amount of long-fiber material present in the leftover food.

[0055] When the food waste extrusion processing device has a crushing device, the process of processing the collected food waste from the dining table is basically the same as described above. The difference is that before spreading the food waste on the oil-permeable plate, the food waste containing long fibers is first poured into the feed inlet of the crushing device, and then crushed into crushed material of about 1cm by the crushing mechanism. The crushed material is then transported to the oil-permeable plate through the conveying pipe.

[0056] 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.
