[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: In one aspect, the present application provides a separation device, comprising: A floating oil separator, which is formed with an inner oil separator area that gradually contracts in a direction away from the liquid surface, and a roll-up portion that extends upward is formed on the peripheral side of the floating oil separator, and the roll-up portion is formed with an outer oil separator area that opens upward; The oil storage member is detachably connected to the floating oil separation member, and an oil storage cavity connected to the inner oil separation area is formed in the oil storage member. The oil storage member is made of elastic material and has a switch member formed thereon for controlling the connection state between the oil storage cavity and the outside world.

[0007] In some embodiments of the present application, a first docking portion is formed on the floating oil distributor, and a second docking portion is formed on the oil storage member, and the first docking portion is detachably connected to the second docking portion.

[0008] In some embodiments of the present application, a docking channel is formed in the second docking portion, a limiting portion is formed on the inner wall of the docking channel, and a clamping portion is formed on the outer wall of the first docking portion. In the installed state, the clamping portion is connected to the limiting portion.

[0009] In some embodiments of the present application, the limiting portion is an annular groove formed on the inner wall of the docking channel, and the clamping portion is a protrusion formed on the outer wall of the first docking portion and extending outward.

[0010] In some embodiments of the present application, a valve port is formed on the top of the oil storage member, and the switch member is connected to the valve port to control the switch state of the valve port.

[0011] In some embodiments of the present application, the switch member includes a sealing portion and a plug-in portion formed at the bottom of the sealing portion, and the outer diameter of the valve port is larger than the outer diameter of the plug-in portion and smaller than the outer diameter of the sealing portion.

[0012] In some embodiments of the present application, a positioning groove extending along the movement direction of the plug-in portion is formed on the inner wall of the valve port, and a positioning portion adapted to the guide groove is formed at the bottom of the plug-in portion.

[0013] In some embodiments of the present application, a first identification portion is formed on the sealing cover portion, and a second identification portion is formed on the oil storage member, for indicating the relative position status of the positioning groove and the positioning portion.

[0014] In some embodiments of the present application, the floating oil separator is made of 304 stainless steel; the oil storage member is spherical and is made of heat-resistant rubber.

[0015] On the other hand, the present application also proposes a separation method, which uses any of the above-mentioned separation devices, and the method specifically comprises the following steps: Place the items to be blanched in a pot filled with water; The separation device is placed in a pot, the separation device floats on the water surface, the peripheral height of the rolled portion is higher than the first water level line, the inner oil separation area is in contact with water, and the outer oil separation area is separated from water; The oil storage member is squeezed, the switch member is opened, the oil storage chamber is connected with the outside, and the gas in the oil storage chamber is discharged to the outside through the switch member; the oil storage member is released, the switch member isolates the oil storage chamber from the outside, and water enters the oil storage chamber through the inner oil separation area; The above-mentioned squeezing and releasing process is repeated on the oil storage member so that the water level in the oil storage chamber reaches the second water level line.

[0016] The cookware is heated, and during the heating process, the separated matter produced by the blanching part is transported to the oil storage cavity through the inner oil separation area; After a preset time, the separation device is moved down until the water covers the outer periphery of the roll-up portion, and the remaining objects to be separated between the separation device and the pot enter the outer oil separation area; The separation device is lifted up and separated from the water. In this state, the objects to be separated are concentrated in the oil storage cavity and the external oil separation area.

[0017] Compared with the prior art, the advantages and positive effects of the present invention are: The separation device and separation method involved in the present application can be directly placed in a pot for cooking the item to be blanched. The floating oil separator floats on the surface of the water under the action of its own buoyancy. The oil storage component is installed above the floating oil separator. The floating oil separator forms an inner oil separation area directly in contact with the water surface. The inner oil separation area is connected with the oil storage cavity in the oil storage component. Before cooking, the oil storage component is manually squeezed to open the switch component on it, and the gas in the oil storage cavity is output from the switch component. Under the action of pressure, water is input into the oil storage cavity through the inner oil separation area to reach the second water level line position. During the cooking process, since the mass of oil and floating foam is relatively light, they are concentrated in the oil storage cavity as the water boils. The outer oil separation area around the floating oil separation part is always above the water surface during the blanching process. When the blanching is finished, the user presses down the separation device until the edge of the roll-up part is below the water surface to collect the oil, water and floating foam around the separation device. The separation device does not need to repeatedly change water when the meat is waiting to be blanched and stewed, thereby maintaining the taste of the meat. The floating oil and foam are concentrated in the oil storage chamber by utilizing their own characteristics, and the user does not need to skim them constantly. The operation is simple and convenient, which reduces the burden on users and provides a good user experience.

[0026] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0027] refer to Figure 1 The present invention proposes a separation device, which includes a floating oil separator 300 and an oil storage member 400. The floating oil separator 300 and the oil storage member 400 are detachably connected. When in use, the separation device is placed in a pot 100 containing a meat waiting to be blanched 200.

[0028] The outer circumference size of the floating oil separator 300 is slightly smaller than that of the cooker 100 , and a gap is formed between the floating oil separator 300 and the cooker 100 .

[0029] The floating oil separator 300 is a shell structure, and a roll-up portion 310 extending away from the water surface is formed on the circumference thereof, that is, the edge of the roll-up portion 310 is bent upward.

[0030] The middle part of the floating oil separator 300 is trumpet-shaped, and an inner oil separator 301 is formed therein, which gradually contracts in the direction away from the liquid surface. The rolled portion 310 of the floating oil separator 300 forms an outer oil separator 302 which opens upward.

[0031] In a static state, the floating oil separator 300 floats on the water surface, the inner oil separator area 301 is in direct contact with the water surface, and the water level at the gap between the cookware 100 and the floating oil separator 300 is defined as a first water level line.

[0032] It is necessary to ensure that, in a stationary state, the first water level is lower than the edge of the roll-over portion 310 , that is, the outer oil separation area 302 is in a separated state from the water surface.

[0033] When the separation is completed, the user gently presses down the separation device so that the outer periphery of the roll-up portion 310 moves below the first water level line, and the floating foam and floating oil on the side of the floating oil separator 300 enter the outer oil separation area 302 from the outer edge of the roll-up portion 310, making the separation more thorough.

[0034] During design, the relationship between the gravity of the separation device and the buoyancy of water is comprehensively considered so that when the water surface is still, the first water level line is located below the edge of the roll-up portion 310 .

[0035] The floating oil separator 300 is preferably made of food grade 304 stainless steel and is formed by stamping and / or spinning processes, which has the advantages of simple process, high temperature resistance, and easy cleaning. Of course, it can also be made of other food grade materials.

[0036] The oil storage member 400 is detachably connected to the floating oil separation member 300 , and an oil storage cavity communicating with the inner oil separation area 301 is formed in the oil storage member 400 .

[0037] That is, the upper part of the inner oil separation area 301 is connected to the oil storage chamber, so that floating oil, floating foam and other impurities can be transported from the inner oil separation area 301 to the oil storage chamber.

[0038] The oil storage member 400 is made of elastic material and is spherical. The material of the oil storage member 400 is heat-resistant rubber to prevent burns.

[0039] The user can squeeze the oil storage member 400 , and a switch member 500 is formed on the oil storage member 400 for controlling the connection state between the oil storage chamber and the outside.

[0040] During use, the user squeezes the oil storage member 400. As the squeezing progresses, the volume of the oil storage chamber becomes smaller, the switch member 500 opens, and the gas in the oil storage chamber is discharged from the switch member 500. After the user releases the oil storage member 400, the switch member 500 is immediately closed.

[0041] Due to the effect of air pressure and the like, the water in the cooker 100 is transported to the oil storage cavity through the inner oil separation area 301, and the oil storage member 400 is repeatedly squeezed until the water level in the oil storage cavity rises to the second water level line position.

[0042] The second water level line is defined to be located in the middle of the oil storage cavity. The oil storage member 400 is in a translucent state. A marking line can be set on the outer wall of the oil storage member 400. The user can observe the real-time water level from the outer wall and stop squeezing in time.

[0043] In view of the above separation device, the present application also proposes a separation method, which specifically comprises the following steps: Step 1: Place the meat or other items to be blanched 200 into a pot 100 filled with water. Initially, the water in the pot 100 is cold water. As the water temperature rises, blood, foam and other impurities in the items to be blanched 200 can be gradually removed.

[0044] Step 2: placing the separation device in the cooker 100, the separation device floats on the water surface, and the peripheral height of the rolled portion 310 is higher than the first water level line, the inner oil separation area 301 is in contact with the water, and the outer oil separation area 302 is separated from the water; Step 3: The user squeezes the oil storage member 400 by hand, the switch member 500 on the oil storage member 400 opens, the oil storage chamber is connected with the outside, and the gas in the oil storage chamber is discharged to the outside through the switch member 500; after squeezing, the oil storage member 400 is released, and the switch member 500 can quickly isolate the oil storage chamber from the outside, and the oil storage chamber is in a low-pressure state. Under the action of the pressure difference, the water in the pot 100 enters the oil storage chamber through the inner oil separation area 301; Step 4: According to the water level entering the oil storage chamber, the above-mentioned squeezing and releasing process is repeated on the oil storage member 400 so that the water level in the oil storage chamber reaches the second water level line.

[0045] Step 5: The cooker 100 is heated. During the heating process, the separated substances produced by the blanching part 200 are transported to the oil storage cavity through the inner oil separation area 301 under the driving effect of its own gravity and boiling water; Step 6: After the preset time, move the separation device down until the water covers the outer periphery of the rolled portion 310, and the residual objects to be separated between the separation device and the cooker 100 enter the outer oil separation area 302. The preset time can be the end of cooking, or it can be the time after the impurities in the blanching part 200 to be blanched are basically separated based on experiments and experience.

[0046] Step 7: Hold the oil storage member 400 or provide a handle on the oil storage member 400, lift the separation device by the handle, and separate it from the water. In this state, the objects to be separated are concentrated in the oil storage cavity and the external oil separation area 302.

[0047] refer to Figure 2 The floating oil separator 300 is detachably connected to the oil storage member 400 to facilitate later cleaning. Specifically, in some embodiments of the present application, a first docking portion 320 is formed on the floating oil separator 300, and a second docking portion 410 is formed on the oil storage member 400. The first docking portion 320 is detachably connected to the second docking portion 410.

[0048] The first docking portion 320 and the second docking portion 410 are both cylindrical. A docking channel is formed in the second docking portion 410 , and the first docking portion 320 is inserted into the docking channel of the second docking portion 410 .

[0049] The first docking portion 320 is formed with a drainage channel, and water, foam, oil and water, etc. are transported to the oil storage cavity through the drainage channel.

[0050] In order to improve the stability and firmness of the connection between the floating oil distributor 300 and the oil storage part 400, a limiting portion is formed on the inner wall of the docking channel of the second docking part 410, and a clamping portion is formed on the outer wall of the first docking part 320. In the installed state, the clamping portion is connected to the limiting portion to prevent the floating first docking part 320 from falling out of the second docking part 410.

[0051] Specifically, in some embodiments of the present application, the limiting portion is an annular groove formed on the inner wall of the docking channel, and the clamping portion is a protrusion formed on the outer wall of the first docking portion 320 and extending outward.

[0052] Since the oil storage member 400 is an elastic member, the clamping portion can pass through the docking channel of the oil storage member 400 and be clamped in the limiting portion, thereby improving the tightness of the connection.

[0053] In addition, after the first docking portion 320 is inserted into the docking channel of the second docking portion 410 , the outer wall of the second docking portion 410 may be clamped by a clamping member to improve the connection firmness between the first docking portion 320 and the second docking portion 410 .

[0054] refer to Figure 3-Figure 5 In some embodiments of the present application, a valve port 420 is formed at the top of the oil storage member 400 , and a switch member 500 is connected to the valve port 420 to control the switch state of the valve port 420 .

[0055] The valve port 420 is specifically a through hole penetrating the outer wall of the oil storage member 400. When the valve port 420 is opened, the oil storage chamber is connected to the outside, and when the valve port 420 is closed, the oil storage chamber is sealed.

[0056] In some embodiments of the present application, the switch member 500 includes a sealing portion 520 and a plug-in portion 510 formed at the bottom of the sealing portion 520 , and the outer diameter of the valve port 420 is larger than the outer diameter of the plug-in portion 510 and smaller than the outer diameter of the sealing portion 520 .

[0057] During step 5, when the user squeezes the oil storage member 400, the gas pushes the switch member 500 outward. At this time, the sealing portion 520 is separated from the valve port 420. The size of the valve port 420 is larger than the plug-in portion 510, and the valve port 420 is in an open state. The gas in the oil storage chamber can be discharged from the gap formed between the valve port 420 and the plug-in portion 510.

[0058] The user releases the oil storage member 400 , the switch member 500 falls, and the cover portion 520 closes the valve port 420 .

[0059] In order to improve the tightness of fit between the covering part 520 and the valve port 420, the bottom of the covering part 520 is a plane, and a contact part 422 that matches the shape of the covering part 520 is formed on the surrounding side of the valve port 420. The contact part 422 is a cross-section formed on the surface of the oil storage part 400 to improve the fit between the covering part 520.

[0060] In some embodiments of the present application, in order to limit the switch element 500 during the switching process and prevent it from falling out of the valve port 420, a positioning groove 421 extending along the movement direction of the plug-in portion 510 is formed on the inner wall of the valve port 420, and a positioning portion 511 adapted to the guide groove is formed at the bottom of the plug-in portion 510.

[0061] During installation, the positioning portion 511 is matched with the position of the positioning groove 421, and the positioning portion 511 extends from the position of the positioning groove 421 to the inner side of the valve port 420. After the installation is completed, the switch component 500 is rotated at a certain angle so that the positions of the positioning portion 511 and the positioning groove 421 are staggered. Then, during the switching process of the switch component 500, the positioning portion 511 plays a limiting role.

[0062] refer to Figure 6 , Figure 7 In order to facilitate the disassembly of the switch component 500, a first identification portion 521 is formed on the cover portion 520, and a second identification portion 430 is formed on the oil storage component 400, which is used to indicate the relative position status of the positioning groove 421 and the positioning portion 511. When the switch component 500 is disassembled, the first identification portion 521 and the second identification portion 430 are matched, so that the positioning groove 421 and the positioning portion 511 are adapted to facilitate the disassembly of the switch component 500.

[0063] Below, the specific working process of the separation device is further described: The meat to be blanched 200 is placed in a pot 100 filled with water. Before heating and ignition, a separation device is placed in the pot 100 to separate and freely float on the water surface.

[0064] The operator squeezes the oil storage member 400 by hand and ensures that the outer edge of the roll-up portion 310 does not fall below the first water level. During the squeezing process, the internal air pressure of the oil storage chamber pushes the opening switch member 500 upward to open the valve port 420 and discharge the air in the oil storage member 400. After releasing the hand, the switch member 500 quickly seals the valve port 420, and the water level in the inner oil separation area 301 rises. The above steps are repeated several times until the water level rises to the second water level of the oil storage chamber.

[0065] When cooking is started, as the water temperature rises, impurities, blood, lymph and solid fat inside and on the surface of the blanching member 200 will turn into foam and liquid grease floating on the water surface, forming an oil layer and a foam layer.

[0066] When the water boils, the power provided by the boiling will transport the floating foam and floating oil into the oil storage chamber and replace the water there.

[0067] After the water boils, the fire is turned to low heat, so that the blanching parts 200 can be cooked faster with less evaporation of water and less energy consumption. Even if the fire is not adjusted to low heat, the collection of floating oil and foam is not affected.

[0068] The separation device can also be used in an automatic cooking machine. During the process of stewing over a low fire, regular stirring can allow the floating foam and floating oil to fully overflow and will not adhere to the surface of the blanching part 200, without the need for secondary cleaning.

[0069] After stewing is finished, gently press down the oil storage part 400 to let the entire separation device descend, and the first water level line rises relatively. A small amount of floating oil and foam remaining between the pot 100 and the floating oil separation part 300 will enter the outer oil separation area 302. Finally, hold the lower part of the oil storage part 400 or the preset handle on the oil storage part 400 to take out the separation device for cleaning.

[0070] Of course, the separation device can also be taken out after a preset time. Based on experience or experiments, the user can take out the separation device after the preset time and before the meat is cooked, which is convenient for seasoning and other operations during the cooking process.

[0071] The separation device involved in this application fully considers practicality and processing convenience, so that there is no need to pour out the water from the meat (the main purpose is to remove floating foam and floating oil) and add cold water to heat it again during cooking, which can reduce cooking time and energy consumption, keep the meat waiting for blanching for 200 minutes soft and not dry or fishy, ​​and also reduce the nutritional loss of blanching.

[0072] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0073] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
