Description

Technical Field

[0001] This invention relates to the technical field of camellia oil processing, and in particular to a coarse grinding device and production process for processing all components of camellia oil. Background Technology

[0002] Oil tea is one of the most famous snacks in Gongcheng and the neighboring county of Guanyang. The ingredients needed to make oil tea include: tea leaves, corn, ginger, garlic, pork, peanuts, scallions, pickled chili peppers, mung beans, rice noodles or noodles. The traditional method of making oil tea is to use old tea leaves as the main ingredient, stir-fry them in oil until they are slightly browned and fragrant, add salt and water and boil them. Most people add ginger to boil them together. The taste is strong and astringent, with a spicy kick. In Gongcheng, ground peanut powder is added, enriching the flavor and reducing its astringency. The perfect cooking time further contributes to Gongcheng's reputation as the best oil tea in the region. Gongcheng has been recognized as a "Longevity Town" in China, and the secret to its longevity is closely related to oil tea. From a Western nutritional perspective, tea leaves are rich in trace elements such as zinc, manganese, and magnesium, which can replenish the body's deficiencies. While ordinary green tea is simply steeped in boiling water, oil tea involves additional roasting and crushing steps, better releasing the trace elements and promoting absorption. Based on traditional oil tea, the people of Gongcheng have developed concentrated oil tea and ready-to-eat pre-packaged oil tea. Concentrated oil tea is a brown powder that needs to be brewed with boiling water, while ready-to-eat pre-packaged oil tea requires the use of oil tea production equipment during processing (see publication number CN210). 356094U discloses an "extraction device for camellia oil production", which includes a cement floor, support legs and an oil press body respectively arranged on the top of the cement floor. An oil inlet pipe is fixedly connected to one side surface of the oil press body. The support legs are arranged in a rectangular array on the top of the cement floor. A worktable is fixedly connected to the top surface of the support legs. An extraction device is arranged on the top of the worktable, and the extraction device includes an extraction barrel. The top of the worktable is fixedly connected to the lower surface of the extraction barrel. A motor is fixedly installed on the upper surface of the extraction barrel. This extraction device for camellia oil production has a filter device arranged on the inner wall of a limiting groove. The filter device includes a protrusion. The inner wall of the limiting groove is slidably inserted into one end of the protrusion, which achieves the effect of further filtering the extracted camellia oil and solves the problem of low extraction efficiency of existing extraction devices for camellia oil.

[0003] The existing processing technology usually involves putting ginger, garlic, and brewed tea leaves into a pot, heating them, and using a pounding method to extract the plant essence. The resulting tea juice is then filtered. After several rounds of filtering, the solid materials need to be discarded. However, the discarded solids actually contain many beneficial substances. Directly discarding them is wasteful and also affects the taste of the tea. Summary of the Invention

[0004] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a coarse grinding device and production process for processing all components of camellia oil, in order to solve the problems mentioned in the background regarding the existing processing technology. In the production of camellia oil, ginger, garlic and brewed tea leaves are usually put into a pot and heated, and the plant essence is extracted by pounding. The resulting camellia oil juice is then filtered. After several cycles, the solid materials need to be discarded. However, the discarded solids actually contain many beneficial substances.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coarse grinding device for processing whole-component camellia oil includes a base and grinding tubes.

[0007] Furthermore, the centerlines of the fixing frame, the tank body, the bottom cover, and the top cover are all on the same vertical straight line, and a liquid filling port is installed on the upper side of one side of the tank body.

[0008] Furthermore, a bottom cover is installed at the bottom of the tank, and a liquid outlet pipe is installed at the bottom of the bottom cover. Four liquid outlet pipes are arranged at equal angles about the vertical axis of the bottom cover. A liquid outlet valve is installed at the bottom of the bottom cover, and a baffle is installed on the inner wall of the bottom cover. The axis of the liquid outlet valve and the axis of the bottom cover are on the same vertical line. A liquid outlet pipe is installed at the bottom of the liquid outlet valve.

[0009] Furthermore, each of the aforementioned grinding tubes is equipped with a connecting pipe at its bottom, and each connecting pipe is connected to a liquid outlet pipe; each of the aforementioned grinding tubes is equipped with a liquid inlet valve at the lower part of its outer wall, and each liquid inlet valve is connected to the bottom of a liquid return pipe.

[0010] Furthermore, four return pipes are arranged at equal angles about the vertical axis of the tank, and all four return pipes are installed inside the tank. At the same time, the top ends of the four return pipes pass through the top cover and are connected to the inlet of the circulation pump.

[0011] Furthermore, the inner diameter of the grinding tube is larger than the outer diameter of the inner tube, and the bottom of the inner tube is connected to the adapter tube; there is a gap between the inner wall and the outer wall of the inner tube, and a set of grinding strips is installed on the inner wall of each inner tube, and each set of grinding strips is arranged at equal angles about the vertical axis of the inner tube; a control air valve is installed on the upper part of each grinding tube.

[0012] Furthermore, the centerlines of the liquid collecting hopper, the filter hopper, and the top cover are all on the same vertical line, and the bottom of the filter hopper has a grid structure.

[0013] Furthermore, the slag discharge pipe has an "L" shaped structure, and a second drive motor is installed at the end of the slag discharge pipe; the output shaft of the second drive motor is connected to one end of the slag discharge rod, and the slag discharge rod is installed inside the slag discharge pipe; a slag discharge valve is installed at the lower part of the end of the slag discharge rod near the second drive motor.

[0014] A whole-component camellia oil processing production process includes grinding the camellia oil raw materials into a pulp using the aforementioned whole-component camellia oil processing coarse grinding device.

[0015] Specifically, the steps include the following:

[0016] A. Grinding section:

[0017] 1) Pre-grind the camellia oil at a material-to-water ratio of 1:3;

[0018] 2) Use the above-mentioned coarse grinding device for wet crushing and coarse grinding, with a grinding water temperature of 60-70℃; sweet tea oil is coarsely ground at a material-to-water ratio of 1:3-5, and salty tea oil is coarsely ground at a material-to-water ratio of 1:2-4.

[0019] 3) Vacuum degassing and cooling, pulp outlet temperature is 25-30℃;

[0020] B. Jet milling:

[0021] 1) Use a plate heat exchanger to cool the slurry to 15-25℃ to ensure more stable operation of the high-pressure jet mill and improve the service life of core components;

[0022] 2) The slurry is treated with a dual filter containing a 60-mesh pre-filter and a high-pressure jet mill. The high-pressure jet pressure is 110-130MPa. When the high-pressure jet mill is working, the slurry temperature rises by 20-25℃ and the discharge temperature is less than 55℃. The fineness diameter of the slurry after treatment by the high-pressure jet mill is reduced to 50-70μm.

[0023] 3) It is transported to the subsequent blending process for blending and homogenization, and finally sterilized and filled.

[0024] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0025] 1. In this invention, a grinding tube, an inner tube, and a grinding shaft are provided. After the raw material enters the inner tube, it is crushed and ground by the rotating grinding shaft in conjunction with the grinding strip. The inner tube has a double-layer structure, with both the inner and outer layers having a grid structure. At the same time, the gap of the outer grid structure is smaller than that of the inner grid structure. During the production process, some of the solid raw material that is not fully crushed will be blocked between the two layers of the inner tube until it is circulated and crushed to a suitable size before passing through the outermost layer of the inner tube and being discharged into the grinding tube, thereby improving the grinding effect.

[0026] 2. In this invention, a circulation pump is provided, which drives the raw material to circulate between the tank and the grinding tube. During the circulation process, the raw material participates in crushing and grinding. Compared with traditional grinding methods, this can effectively improve the grinding efficiency and grinding uniformity.

[0027] 3. In this invention, a liquid collection hopper and a filter hopper are provided. During the processing, a small amount of solid raw material will be deformed due to the pressure difference and will return to the tank through the inner tube in an incompletely crushed state. Therefore, filtering it through the filter hopper can improve the grinding effect and reduce the chance of clogging the inner tube, thereby improving the performance.

[0028] 4. In this invention, a slag discharge pipe, a second drive motor, and a slag discharge rod are provided. By starting the second drive motor to drive the slag discharge rod to rotate, the solid raw materials accumulated inside the filter hopper can be moved into the slag discharge pipe and compressed. After a single raw material processing is completed, during the discharge process, the slag discharge valve is activated, which can quickly discharge the solid residue accumulated inside the slag discharge pipe. The entire processing process can keep the inside of the tank in a relatively closed state, reducing the probability of contamination and improving the safety of use.

[0029] 5. In this invention, the whole-component camellia oil processing technology can make full use of the raw materials. Through the ultra-fine grinding process, the solid suspended particles in the slurry are fully broken down, so that the solid-liquid mixture containing fine camellia oil particles is a multiphase flow that efficiently homogenizes, emulsifies and pulverizes without the need for slag removal. This can effectively improve the fineness of the product, enhance the taste and flavor of the product, and at the same time improve the stability of the product.

[0030] To more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0047] In this embodiment, a bottom cover 4 is installed at the bottom of the tank body 3, and a liquid outlet pipe 5 is installed at the bottom of the bottom cover 4. Four liquid outlet pipes 5 are arranged at equal angles about the vertical axis of the bottom cover 4. A liquid outlet valve 6 is installed at the bottom of the bottom cover 4, and a baffle 26 is installed on the inner wall of the bottom cover 4. The axis of the liquid outlet valve 6 and the axis of the liquid outlet pipe 7 of the bottom cover 4 are on the same vertical line. A liquid outlet pipe 7 is installed at the bottom of the liquid outlet valve 6.

[0048] More specifically, all four liquid outlet pipes 5 are connected to the interior of the tank body 3, and the connection points of the four liquid outlet pipes 5 to the tank body 3 are all located below the baffle 26.

[0049] As a further explanation of this embodiment, the side of the baffle 26 is provided with multiple through groove structures.

[0050] In this embodiment, each of the grinding tubes 8 is equipped with a transfer pipe 9 at its bottom, and each transfer pipe 9 is connected to a liquid outlet pipe 5; each of the grinding tubes 8 is equipped with a liquid inlet valve 15 at the lower part of its outer wall, and each liquid inlet valve 15 is connected to the bottom of a liquid return pipe 16.

[0051] More specifically, each grinding tube 8 has a threaded opening on the bottom inner side for connecting the inner tube 10, which facilitates the disassembly and assembly of the inner tube 10.

[0052] As a further explanation of this embodiment, the liquid inlet valve 15 facilitates the flow of the juice after grinding through the grinding tube 8 into the return pipe 16, which is then circulated by the circulation pump 18 to improve the grinding effect.

At the same time, the top ends of the four return pipes 16 all pass through the top cover 17 and are connected to the inlet end of the circulation pump 18.

[0054] More specifically, the circulation pump 18, in conjunction with the return pipe 16, draws the juice from inside the four grinding tubes 8 into the collection hopper 20.

[0055] As a further explanation of this embodiment, the circulating pump 18 is a 10t / h self-priming pump made of SUS304.

[0056] In this embodiment, the inner diameter of the grinding tube 8 is larger than the outer diameter of the inner tube 10, and the bottom of the inner tube 10 is connected to the adapter tube 9; there is a gap between the inner wall and the outer wall of the inner tube 10, and a set of grinding strips 13 are installed on the inner wall of each inner tube 10, and each set of grinding strips 13 is arranged at equal angles about the vertical axis of the inner tube 10; a control air valve 14 is installed on the upper part of each grinding tube 8.

[0057] More specifically, the control valve 14 can be opened or closed as needed, making it easy to adjust the internal air pressure of the grinding tube 8. The grinding strips 13 on the inner wall of the inner tube 10 work with the rotating grinding shaft 12 to crush the solid raw materials. The grinding shaft 12 has a screw structure.

[0058] As a further explanation of this embodiment, the inner tube 10 has a double-layer structure. Both the inner and outer layers of the inner tube 10 are grid structures. At the same time, the gap of the outer grid structure is smaller than the gap of the inner grid structure. During the production process, some solid raw materials that are not fully crushed will be blocked between the two layers of the inner tube 10 until they are circulated and crushed to a suitable size before passing through the outermost layer of the inner tube 10 and being discharged into the grinding tube 8, thereby improving the grinding effect.

[0060] More specifically, the raw materials discharged by the circulating pump 18 are collected through the liquid collecting hopper 20.

[0061] As a further explanation of this embodiment, after the raw material is injected into the filter hopper 21, the raw material is filtered through the filter hopper 21, blocking the larger solid raw materials, and allowing some of the larger solid raw materials that are not completely crushed due to deformation caused by suction to pass through the inner tube 10, thus affecting the processing effect.

[0062] In this embodiment, the slag discharge pipe 22 has an "L" shaped structure, and a second drive motor 23 is installed at the end of the slag discharge pipe 22; the output shaft of the second drive motor 23 is connected to one end of the slag discharge rod 24, and the slag discharge rod 24 is installed inside the slag discharge pipe 22; a slag discharge valve 25 is installed at the lower part of the end of the slag discharge rod 24 near the second drive motor 23.

[0064] As a further explanation of this embodiment, the solid raw materials accumulated inside the slag discharge pipe 22 can be quickly discharged by driving the slag discharge rod 24 to rotate by the second drive motor 23.

[0065] In this embodiment, the following steps are included:

[0066] A. Grinding section:

[0067] 1) Pre-grind the camellia oil at a material-to-water ratio of 1:3;

[0068] 2) Use the above-mentioned coarse grinding device for wet crushing and coarse grinding, with a grinding water temperature of 60-70℃; sweet tea oil is coarsely ground at a material-to-water ratio of 1:3-5, and salty tea oil is coarsely ground at a material-to-water ratio of 1:2-4.

[0069] 3) Use a vacuum degasser to remove air bubbles introduced into the slurry from the coarse grinding process, thus avoiding the adverse effects of air bubbles on the operation of the high-pressure jet mill. The slurry outlet temperature should be 25-30℃.

[0070] B. High-pressure jet mill system:

[0071] 1) Use a plate heat exchanger to cool the slurry to 15-25℃ to ensure more stable operation of the high-pressure jet mill and improve the service life of core components;

[0072] 2) The slurry is treated with a dual filter containing a 60-mesh pre-filter and a high-pressure jet mill. The high-pressure jet pressure is 110-130MPa. When the high-pressure jet mill is working, the slurry temperature rises by 20-25℃ and the discharge temperature is less than 55℃. The fineness diameter of the slurry after treatment by the high-pressure jet mill is reduced to 50-70μm.

[0073] 3) It is transported to the subsequent blending process for blending and homogenization, and finally sterilized and filled.

[0074] Coarse grinding device for whole-component camellia oil processing: In use, after injecting raw materials into the tank 3 through the liquid inlet 27, connect the external power supply, start the circulation pump 18, and simultaneously start the four liquid inlet valves 15. Together with the return pipe 16, a negative pressure is created inside the four grinding tubes 8. The raw materials inside the tank 3 are then drawn into the inner tube 10 through the transfer pipe 9 and the outlet pipe 5. At the same time, the four first drive motors 11 are started, driving the four grinding shafts 12 to rotate. The rotating grinding shafts 12, in conjunction with the grinding strips 13, grind and pulverize the solid raw materials until the mixture passes through the inner tube 10 and enters the grinding tubes 8. It then collects in the collection hopper 20 through the return pipe 16. The raw materials then... After the liquid collection hopper 20 is filled into the filter hopper 21, solid raw materials and liquids smaller than the grid gaps on the surface of the filter hopper 21 will pass through the filter hopper 21 and be collected back into the tank 3 for circulation processing. Some larger solid raw materials will be temporarily stored in the filter hopper 21 and gradually transferred to the slag discharge pipe 22 under the action of gravity. After the circulation processing is completed, the first drive motor 11 and the circulation pump 18 are turned off at the same time, the liquid outlet valve 6 is started, and the processed product is discharged through the liquid outlet pipe 7 for further processing. Simultaneously, the second drive motor 23 is started to drive the slag discharge rod 24 to start rotating, and the slag discharge valve 25 is opened to discharge the solid residue accumulated in the slag discharge pipe 22.
