Abstract
Description
Technical Field
[0001] This utility model belongs to the field of cooking and cooking utensils, and specifically relates to a cooking foam collection and filtration device. Background Technology
[0002] In daily cooking, especially in the initial stages of cooking meat products, a lot of foam often floats to the surface of the broth. This is referred to as cooking foam in this application. This cooking foam is the main source of the food's fishy or gamey smell. If not removed promptly, the foam adheres to the food surface and the edge of the pot, or dissolves into the broth, severely affecting the taste and texture of the food. Existing foam removal methods mainly involve using tools such as slotted spoons, funnels, spatulas, and ladles to collect and remove the foam. However, this method has a limited capacity for collecting and removing foam each time, requiring multiple repetitions. The operation is laborious under the influence of heat and poses a risk of eye irritation and burns. Moreover, even after multiple removals, a significant amount of foam still adheres to the food and dissolves into the broth, necessitating further manual washing of the food, making the process very tedious. Utility Model Content
[0003] To overcome the shortcomings of existing solutions and address the problem of how to quickly, efficiently, labor-savingly, and cleanly remove cooking scum while preventing it from adhering to the food surface and pot rim, this invention breaks away from the conventional approach of removing scum after it has formed. It innovatively proposes a cooking scum collection and filtration device, and offers several improved versions for cylindrical and small cooking vessels with wide openings and large bottoms. By designing a filter device with a special shape and structure, the space is divided into a scum generation and storage space and a cooking space. The scum generation and storage space is separated before scum is formed. Foam-forming substances pass through the filter under boiling conditions and then form scum in the scum generation and storage space. This ensures that all cooking scum is contained within the scum generation and storage space. After collecting the scum, all scum is filtered out, thus achieving complete collection and one-time removal of scum. Using the cooking scum collection and filtration device described in this invention will greatly reduce the operational burden of removing cooking scum, avoid safety hazards, and make the food more delicious. The detailed technical solution proposed by this invention is as follows:
[0004] A cooking scum collection and filtration device includes a scum collection and filtration body and a lifting assembly. The scum collection and filtration body comprises a one-way separating filter screen component and a scum collection enclosure component, used to isolate a scum generation and storage space in the cooking vessel so that all cooking scum is generated and stored therein. The one-way separating filter screen component includes a filter screen, the mesh size and density of which meet the requirement that foam-forming substances can freely pass through the scum generation and storage space to form scum before foaming, but cannot pass through the filter screen after foaming. The height of the scum collection enclosure component is sufficient to prevent scum from being washed outside the enclosure under the action of boiling liquid. The one-way separating filter screen component is fixedly connected to or abutted against the scum collection enclosure component to form an upward-opening scum generation and storage space for generating and collecting scum therein. The lifting assembly is connected to the scum collection and filtration body and is used to place or remove the scum collection and filtration body into or remove it from the cooking vessel or adjust the position of the scum collection and filtration body in the cooking vessel.
[0005] Furthermore, different device structures were designed for different cooking utensils.
[0006] For cylindrical cooking vessels, a cooking foam collection and filtration device is applied to collect and filter foam within the vessel. The unidirectional separating filter element is fixedly connected to the foam collection enclosure element to form an upward-opening foam generation and storage space for generating and collecting foam. The foam collection and filtration body also includes a fastening assembly for stably securing the body within the cylindrical cooking vessel, counteracting the upward force of boiling on the body, and flexibly adjusting its height relative to the inner wall of the vessel under external force. This allows adjustment of the filter element's position so that foam only accumulates within the foam generation and storage space. The outer shape and dimensions of the foam collection and filtration body meet the requirements of fitting snugly against the inner wall of the cylindrical cooking vessel and being able to move vertically. The fastening assembly can be a resilient spring integrated into the foam collection enclosure, a screw, or other fastening components that allow for both fixation and flexible adjustment. The carrying component can be a regular handle or a folding handle with a folding function.
[0007] For small cooking vessels with wide openings and small bottoms (such as woks), a cooking foam collection and filtration device is used to collect and filter foam inside such vessels. The outer periphery shape and size of the lower edge of the foam collection and filtration body meet the requirement of closely fitting the inner wall of the small cooking vessel, so that foam only accumulates in the foam generation and storage space. Further optionally, the unidirectional separating filter component is fixedly connected to the foam collection enclosure component to form an upward-opening foam generation and storage space for generating and collecting foam therein. Or further optionally, the foam collection enclosure component has a straight cylindrical wall with openings at the top and bottom; the unidirectional separating filter component is abutted and snapped against the straight cylindrical wall of the foam collection enclosure component to form an upward-opening foam generation and storage space for generating and collecting foam therein. Furthermore, the one-way separating filter component, which is attached to and clipped onto the straight cylindrical wall of the foam collection fence component, also includes a rim rail, a clip, and a handle, for attaching the one-way separating filter component to and clipping onto the straight cylindrical wall of the foam collection fence component and for being able to move up and down and stop.
[0008] Furthermore, the cooking foam collection and filtration device also includes a counterweight component to counteract the upward force of the boiling soup and stabilize the center of gravity, thereby maintaining the cooking foam collection and filtration device in the correct position and orientation. The counterweight component can be a heavy metal body, or it can be made of a high-density material, such as a food-grade stainless steel rod ring, which serves as the edge strip of the foam collection enclosure or filter screen.
[0009] Furthermore, the unidirectional separating filter component also includes a filter skeleton to enhance the robustness and load-bearing capacity of the filter structure.
[0010] Furthermore, the surface of the cooking foam collection and filtration device that comes into contact with the foam has a non-stick coating, or the part of the cooking foam collection and filtration device that comes into contact with the foam is made of a non-foam-stick material, so as to facilitate the emptying of the foam and cleaning of the device.
[0011] The inventors proposed the cooking foam collection and filtration device based on detailed observation of daily life processes and an understanding of the basic principles of foam formation: During high-temperature cooking, soluble proteins, residual blood, lipid particles, and biological macromolecules from food enter the broth. Under the action of high-temperature boiling, some of these foaming or adhesive substances, after reaching the surface of the broth, undergo a complex physicochemical process to deform, bubble, adhere, accumulate, and clump together to form foam. This foam contains a large amount of capillary residual blood and other substances with a strong fishy or pungent smell. If it is not filtered out in time, it will seriously affect the taste of the food and broth. After recognizing this fundamental principle, the inventors broke through the existing mindset of removing foam after it has been generated using tools. They innovatively proposed a foam collection and filtration device for cooking, and developed corresponding foam collection and filtration devices for cylindrical and small cooking vessels with wide mouths and large bottoms. By designing a filter device with a special shape and structure, the space is divided into a foam generation and storage space and a cooking space. The foam generation and storage space is separated before foam is generated. Foam-forming substances pass through the separating filter under boiling and then form foam only in the foam generation and storage space. In this way, all the foam generated during cooking is located within the foam generation and storage space. After collecting the foam, all the foam is filtered out, thus completing the overall collection and one-time removal of foam.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1) Compared with traditional foam removal tools such as slatters and funnels used after foam is generated, the cooking foam collection and filtration device proposed in this utility model separates the foam generation and storage space before foam is generated to collect and store foam. It also proposes corresponding improved versions for cylindrical and small cooking utensils with wide mouths and large bottoms. The foam generation and storage space is separated by a one-way separating filter screen component and a foam collection fence. By placing the device in first and then heating to boiling, the foam is generated and stored only in the foam generation and storage space, thereby realizing the overall collection and one-time removal of cooking foam.
[0014] 2) Compared with existing foam removal tools such as slurries and funnels, which often require repeated operations to remove a certain amount of cooking foam, the cooking foam collection and filtration device proposed in this utility model can filter out the vast majority of foam in one operation, which can not only save a lot of operation time, but also avoid the risk of being scalded by steam during operation.
[0015] 3) Compared with existing cooking foam removal devices, which often require subsequent steps of washing off the foam adhering to the food surface, the cooking foam collection and filtration device proposed in this utility model can filter out the vast majority of foam in one operation, without the need to wash the food again, reducing the operation steps in the cooking process, saving time, and saving water used for washing off foam.
[0016] 4) By using a filter that allows foaming substances to pass freely before foaming but not after foaming, it is possible to collect and filter out most of the fishy and pungent foam, while retaining delicious and nutritious substances such as soluble proteins and lipid particles in the soup. This results in delicious food that is both free of fishy and pungent smell and has high nutritional value, thus reducing food waste caused by poor taste.
[0017] 5) Compared with existing foam removal tools such as slurries and funnels, which still leave a large amount of foam on the side wall of the cooking vessel after the foam removal operation, requiring the soup to be poured out to clean the foam on the side wall; the cooking foam collection and filtration device proposed in this utility model, since the foam is generated and stored in the foam generation and storage space, will basically not leave foam on the side wall of the cooking vessel.
[0018] 6) By providing the cooking foam collection and filtration device with a non-stick coating on the surface in contact with the foam or made of a non-stick material, it is very easy to pour out and clean the foam on the filter screen.
[0019] 7) By proposing the cooking foam collection and filtration device, which also includes a counterweight component, the upward force of boiling soup can be counteracted, and the center of gravity shift and posture instability caused by handles or other reasons can be corrected or alleviated, so as to stably maintain the cooking foam collection and filtration device in the correct position and posture.
[0020] In summary, the cooking foam collection and filtration device proposed in this invention greatly simplifies the process of removing cooking foam, avoids the risk of scalding from steam during foam removal, reduces the number of foam washing steps, saves operating time and water, significantly reduces the workload of foam removal during cooking, improves the user experience, and enhances operational safety. Its application in large-scale cooking scenarios such as pre-prepared dishes can significantly reduce enterprise costs. Using this cooking foam collection and filtration device, delicious food with no fishy or gamey smell and high nutritional value can be obtained, reducing food waste and leftovers caused by poor taste.

Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.
[0034] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this utility model. Therefore, the illustrations only show components relevant to this utility model and are not drawn according to the actual number, shape, and size of the components in the actual implementation. In the actual implementation, the shape, quantity, and proportion of each component can be arbitrarily changed, and the component layout may also be more complex. The mesh density, color, and material of the device are not given in the figures. In the actual implementation, different materials or combinations such as stainless steel mesh, stainless steel perforated plate, aluminum alloy perforated plate, and non-stick multilayer board can be used. The surface can also be covered with a non-stick coating, and the layer color can be various colors with different patterns or designs. The various components or parts of the device can be integrally molded or processed into independent components and then connected and assembled by various forms such as buckles and bolts. It can also be adapted to different cooking utensils by adding a frame or changing the shape and size, so as to be applied in scenarios such as pre-cooked dishes and large pot dishes where foam needs to be removed.
[0035] Example 1: A cooking foam collection and filtration device for use in cylindrical cooking vessels. The structural design of this device can be referenced. Figure 1 The three-dimensional structure diagram shown Figure 2 The front view structure diagram shown Figure 3 The diagram shown is a 3D representation of the pot before the contents are placed inside. Figure 4 The diagram shows the state of the food being placed inside the pot. Figure 5The image shows a three-dimensional sectional view of the device placed inside the pot. The cooking foam collection and filtration device of this embodiment is applied to a cylindrical cooking pot 200, including a foam collection and filtration body 100 and a lifting assembly 151. The foam collection and filtration body 100 includes a one-way separating filter screen component 101, a foam collection fence component 111, and a fastening assembly 112. The one-way separating filter screen component 101 is a filter screen with a frame, and the fastening assembly 112 is a stainless steel sheet with raised resilient points. The lifting assembly 151 is an arched handle. The cylindrical cooking pot 200, as the cooking vessel, is a stainless steel pot with an inner diameter of 28 cm. The one-way separating filter screen component 101 uses double-layer stainless steel strips as a frame, clamping and welding a 10-mesh stainless steel mesh. Experimental testing shows that the 10-mesh stainless steel mesh meets the requirement that foaming substances can freely pass through before foaming but cannot pass through after foaming, and the upward force of boiling on the filter screen is very small and negligible, facilitating stable application of the device. The lifting assembly 151 uses an arched handle made of bent stainless steel strips, welded to the stainless steel skeleton strip of the one-way separating filter component 101. The arched handle is 12 cm high. The foam collecting fence component 111 is made of 0.3 mm thick stainless steel strip. It is first made by stamping three convex, resilient stainless steel sheets as fastening components 112, and then bent into a ring shape and welded together. The height is 6 cm. The foam collecting fence component 111 and the one-way separating filter component 101 are connected by edge welding. The outer diameter of the combined foam collecting fence component 111 and the one-way separating filter component 101 is 27.96 cm. The three convex, resilient stainless steel sheets are stretched into a virtual outer ring with a diameter of 28.1 cm to stably hold the entire device against the inner wall of the cylindrical cooking pot 200 with an inner diameter of 28 cm. When it is necessary to adjust the height or put in or take out the device, the lifting assembly 151 applies external force to change the position of the entire device. In this embodiment, because the convex resilient stainless steel sheet has good adhesion and locking ability, no separate counterweight component is required. Figure 3 , Figure 4 , Figure 5 The diagram clearly illustrates the positional and spatial relationships between this embodiment and the pot body, both in use and when not in use. Two spaces are formed between the one-way separating filter component 101, the foam collection enclosure component 111, and the inner wall 200 of the cylindrical cooking pot. One is the cooking space 500 formed by the bottom and side walls of the cylindrical cooking pot 200 and the one-way separating filter component 101; the other is the foam generation and storage space formed by the one-way separating filter component 101 and the foam collection enclosure component 111, which is not shown in the diagram due to its inconvenience. All stainless steel components in this embodiment are made of 316 stainless steel.
[0036] The steps of using the cooking scum collection and filtration device of this embodiment are roughly as follows: Adjust the handle 151 so that the one-way separating filter screen component 101 is below the liquid surface in the cylindrical cooking pot 200, separating the scum generation and storage space and the cooking space in the cylindrical cooking pot 200; heat the cylindrical cooking pot 200 until the soup enters and maintains a boiling state to collect scum. In the boiling state, the scum is generated in the scum generation and storage space and stored therein. Observe the amount of scum generated and accumulated in the scum generation and storage space; after the amount of cooking scum collected reaches the expected amount, lift the entire device with the handle 151, and all the scum is filtered up and poured out, realizing one-time removal of cooking scum.
[0037] By implementing the device of this embodiment, cooking scum can be collected and removed in one go. Compared with cooking scum removal methods such as using a strainer or funnel, it has many advantages. Table 1 shows a comparison of the implementation effects of the two methods.

[0040] Example 2: A cooking foam collection and filtration device for wok-type cooking vessels, the structural design of which can be referred to Figure 6 The three-dimensional structure diagram shown Figure 7The image shows a three-dimensional sectional view of the device placed inside a pot. The cooking foam collection and filtration device of this embodiment is applied to a wok 300 and includes a foam collection and filtration body 100 and a lifting assembly 121. The foam collection and filtration body 100 includes a one-way separating filter screen component 101 and a foam collection enclosure component 111. The lifting assembly 121 is a handle. The wok 300, as the cooking vessel, is an iron wok with an upper diameter of 32 cm. The one-way separating filter screen component 101 is made of 10-mesh stainless steel mesh. Experimental testing shows that a 10-mesh stainless steel mesh meets the requirement that foaming substances can freely pass through before foaming but cannot pass through after foaming, and that boiling will not cause significant upward force on the filter screen. The handle 121 is made of a wooden handle and stainless steel connectors and is fixed to the ring wall of the foam collection enclosure component 111 by bolts. The foam collection enclosure component 111 is made of 0.3 mm thick stainless steel strip bent into a ring and welded, with a height of 5 cm. The foam collection fence component 111 and the one-way separating filter component 101 are connected by edge pressing. The outer diameter of the assembled foam collection fence component 111 and one-way separating filter component 101 is 27 cm. Placed inside the wok 300, it adheres to the inner wall of the wok 300 by gravity. The entire device can be placed into or removed from the wok using the handle 121. This embodiment does not have a height adjustment function; during use, the device must be held by hand or placed on the wok handle to ensure that the filter screen of the one-way separating filter component 101 is below the liquid surface. Figure 7 The diagram clearly illustrates the positional and spatial relationships between this embodiment and the pot body during use. Two spaces are formed between the one-way separating filter component 101, the foam collection enclosure component 111, and the inner wall of the wok 300: one is the cooking space 500 formed by the bottom and side walls of the wok and the one-way separating filter component 101; the other is the foam generation and storage space formed by the one-way separating filter component 101 and the foam collection enclosure component 111, which is not shown in the diagram due to its inconvenience.
[0041] The steps for using the cooking scum collection and filtration device of this embodiment are roughly as follows: First, add the ingredients and water to be scum removed into the wok 300; then, place the cooking scum collection and filtration device of this embodiment into the wok 300 through the handle 121, and reduce the water level by adding or removing water so that the filter screen 101 is below the liquid surface in the wok 300, thus separating the scum generation and storage space and the cooking space in the wok 300; heat the wok 300 until water enters and maintains a boiling state to collect scum. In the boiling state, scum is generated in the scum generation and storage space and stored therein, and the amount of scum generated and collected in the scum generation and storage space is observed; after the amount of cooking scum collected reaches the expected level, lift the entire device through the handle 121, and all the scum is filtered out; pour out all the scum, achieving one-time removal of cooking scum.
[0042] Implementing this embodiment has most of the benefits of embodiment 1, which will not be repeated here. However, the size of the cooking space that the cooking foam collection and filtration device of this embodiment can divide is fixed, and the amount of water cannot be adjusted according to the amount of ingredients during use.
[0043] Figure 8 The experiment conducted by the inventor is shown in comparison images. We used a camera to record the actual effects of cooking pork ribs at different stages under three conditions: no filter, 24-mesh filter, and 10-mesh filter. As can be seen from the images, a lot of foam is produced when cooking pork ribs. By using a foam removal device containing a 10-mesh filter that meets the requirements of this utility model, foam can be collected and stored during boiling, and most of the foam can be filtered out after it is produced, so that only nutritious pork bone soup is retained in the broth.
[0044] Example 3: An adjustable cooking foam collection and filtration device for wok-type cooking vessels, the structural design of which can be referred to Figure 9 The three-dimensional structure diagram shown Figure 10 The front view structure diagram shown Figure 11The image shows a three-dimensional sectional view of the device placed inside a pot. The cooking foam collection and filtration device of this embodiment is applied to a wok 300, including a foam collection and filtration body 100 and a lifting assembly 121. The foam collection and filtration body 100 includes a one-way separating filter screen component 101 and a foam collection enclosure component 111. The lifting assembly 121 is a handle. The wok 300, as the cooking vessel, is an iron wok with an upper diameter of 32 cm. The handle 121 is made of a wooden handle and stainless steel connectors, and is fixed to the ring wall of the foam collection enclosure component 111 by bolts. The one-way separating filter screen component 101 consists of a filter screen 106, a edging rail 105, a retaining component 103, and a handle 102. The filter screen 106 is made of 10-mesh stainless steel mesh. Experimental testing shows that a 10-mesh stainless steel mesh meets the requirement that foaming substances can freely pass through before foaming but cannot pass through after foaming, and that boiling does not cause significant upward force on the filter screen. The unidirectional separating filter component 101 is vertically attached to the stainless steel fence 111, and its attachment height can be adjusted using the handle 102. The foam collection fence component 111 is made of 0.3 mm thick stainless steel strip bent into a ring and welded, with a height of 10 cm. The foam collection fence component 111 and the unidirectional separating filter component 101 are connected by edge pressing. The outer diameter of the assembled foam collection fence component 111 and the unidirectional separating filter component 101 is 27 cm. It is placed inside the wok 300 and adheres to the inner wall of the wok 300 by gravity. The entire device can be placed into or removed from the wok using the handle 121. This embodiment has a height adjustment function. In use, the unidirectional separating filter component 101 is stably attached to the foam collection fence component 111 by the locking part 103 on the component, and the relative height between the unidirectional separating filter component 101 and the foam collection fence component 111 can be adjusted using the handle 102. Figure 11 The diagram clearly illustrates the positional and spatial relationships between this embodiment and the pot body during use. Two spaces are formed between the unidirectional separating filter component 101, the foam collection enclosure component 111, and the wok 300: one is the cooking space 500 formed by the bottom and side walls of the wok and the filter 106; the other is the upward-facing foam generation and storage space formed by the filter 106, the edging 105, and the foam collection enclosure component 111, which is not shown in the diagram due to its inconvenience. The size of the cooking space that can be separated using the foam collection and filtration device of this embodiment can be adjusted according to the amount of food, giving it higher practical value than Embodiment 2.
[0045] The steps of using the cooking scum collection and filtration device of this embodiment are roughly as follows: Place the cooking scum collection and filtration device of this embodiment into the wok 300 using handle 121, and remove the one-way separating filter screen component 101 from the scum collection enclosure component 111; add the food to be scum removed into the wok through the scum collection enclosure component 111, and then cover it with the one-way separating filter screen component 101; add water so that the filter screen 106 is below the liquid surface in the wok 300, separating the scum generation and storage space and the cooking space within the wok 300; heat the wok 300 until water enters and is maintained at a boiling state to collect the scum. During the boiling state, the scum is generated in the scum generation and storage space and stored therein; observe the amount of scum generated; after the expected amount of cooking scum is collected, lift the entire device using handle 121, and all the scum is filtered out; pour out all the scum, achieving one-time removal of cooking scum.
[0046] Using this embodiment, the amount of water and the size of the cooking space can be adjusted according to the amount of ingredients, and all the technical effects of Embodiment 1 can be achieved in a wok-type cooking vessel, which will not be described in detail here.
