Description

Technical Field

[0001] This invention belongs to the field of extraction equipment technology, specifically an extraction device for food raw materials that are both medicinal and food. Background Technology

[0002] Food ingredients with medicinal properties refer to substances that have both medicinal effects and can be used as food ingredients. These substances are usually derived from plants, animals or minerals in nature and undergo specific processing to ensure their safety and effectiveness. The extraction of active ingredients from substances with both medicinal and food properties in food ingredients with medicinal properties is usually achieved using extraction devices.

[0003] In existing pharmaceutical food ingredient extraction devices, the processing agent is usually placed in a processing cylinder, along with the raw material powder thrown in, and the mixture is thoroughly mixed and extracted by stirring. However, in actual processing, the raw material powder is relatively light and still floats on the surface of the liquid during mixing. In addition, for large amounts of raw material powder, it accumulates on top of the processing agent. Even with stirring, it is still difficult to mix effectively inside the liquid. The overall contact area is small, the mixing uniformity is poor, and the extraction effect of the active ingredients is not good. Summary of the Invention

[0010] Preferably, the movable ring is movably sleeved on the outer side of the mounting column, the liquid suction frame is symmetrically distributed on both sides of the movable ring and fixedly connected, and the suction chamber is opened in the upper part of the liquid suction frame. Liquid is sucked in by using the liquid suction frame. The suction chamber is fully connected to the upper liquid surface of the treatment liquid for easy suction.

[0011] Preferably, the sensing control mechanism includes a first pressure sensor, a positioning ring, and a second pressure sensor. The first pressure sensor is fixed to the top of the assembly cavity. The positioning ring is fixedly sleeved in the assembly cavity and located above the suction end of the support tube.

[0014] Preferably, the upper part of the venting concave tube is higher than the liquid level, and the upper air outlet of the venting concave tube faces downward and is submerged in the liquid.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention utilizes a floating liquid suction component, a lifting mechanism, an execution component, a piston section, and a sensing control mechanism to achieve the suction of raw material powder floating on the surface of the treatment agent liquid. After being sucked in together with the treatment agent, it is sprayed. By using top suction and internal spraying, the raw material powder is mixed and disturbed, improving the mixing uniformity of the raw material powder, thereby improving the separation and extraction efficiency of the target components. Furthermore, through the coordinated control of the float, as the raw material powder at the top is gradually sucked in, it is kept synchronously lowered with the decrease of the treatment agent liquid level, and the suction of the raw material powder at the top is completed at all times, which greatly improves the suction effect, ensures that the total amount of raw material powder sprayed out is sufficient, completes the spraying and mixing, and greatly improves the actual extraction efficiency.

[0017] 2. This invention utilizes the ventilation process of the composite processing component to achieve the input of hot air. With the proper positioning of the ventilation tube, preliminary heat exchange is achieved during the passage through the processing agent. After passing through, hot air is directly injected into the processing agent in a jet-like manner. The impact and disturbance of the airflow on the interior of the processing agent further improves the mixing effect of the processing agent and raw material powder in the processing cylinder, thereby further improving the separation efficiency of the target components in the raw material powder. The results are excellent.

[0018] 3. By utilizing the above-mentioned hot air introduction setting, the present invention fully heats the interior of the treatment agent when it is injected into the treatment agent, thereby improving the extraction effect of the raw material powder and achieving a good overall extraction effect. After the extraction is completed and the interior of the treatment cylinder is emptied, hot air is used to blow dry the interior of the treatment cylinder and complete the cleaning process, resulting in good performance.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figures 1 to 10As shown, this embodiment of the invention provides an extraction device for food ingredients that are homologous to medicinal materials. It includes a processing cylinder 1, an installation column 2 fixedly mounted inside the processing cylinder 1, an assembly cavity 6 inside the installation column 2, a piston 5 movably fitted inside the assembly cavity 6, a floating liquid suction assembly 4 on the outer side of the installation column 2 communicating with the assembly cavity 6, a switching assembly 8 movably fitted inside the assembly cavity 6, a spray outlet 7 on the outer surface of the installation column 2, a lifting mechanism 3 fixedly mounted on the top of the processing cylinder 1, a sensing control mechanism inside the assembly cavity 6, and an execution assembly 12 fixedly mounted on the top of the processing cylinder 1. The piston part 5 moves upward and sucks in the raw material floating above the solvent through the floating liquid suction assembly 4. The piston part 5 moves downward and sprays the sucked raw material mixed with solvent through the spray outlet 7 through the switching assembly 8. The floating liquid suction assembly 4 includes a movable ring 41, a connecting pipe 42, a support pipe 43, a liquid suction frame 44, a float 45 and a suction chamber 46. The support pipe 43 is fixed to the outside of the mounting column 2 and communicates with the assembly chamber 6. One end of the connecting pipe 42 is movably sleeved in the support pipe 43, and the other end passes through the movable ring 41 and the liquid suction frame 44 and communicates with the suction chamber 46. The liquid suction frame 44 floats on the top layer of the liquid surface through the float 45 fixed at the bottom.

[0032] Example 1: During the extraction process, the treatment agent is poured into the treatment cylinder 1, and the raw material powder to be treated is poured into the treatment cylinder 1. Some of the raw material powder floats above the surface of the treatment agent liquid, and the floating liquid suction assembly 4 floats above the liquid surface through the float 45. The lifting mechanism 3 is activated, and the lifting mechanism 3 drives the piston part 5 to move inside the mounting column 2. The upward movement causes the piston part 5 to draw air from the inside of the floating liquid suction assembly 4 through the assembly cavity 6, and to draw liquid from the liquid surface above the liquid surface through the suction frame 44. This allows the raw material powder floating on top of the treatment agent and the treatment agent to be drawn together into the connecting pipe 42, and then into the assembly cavity 6 through the support pipe 43. As the liquid level decreases, the floating liquid suction assembly 4 gradually lowers and continues to draw the treatment agent and raw material powder above the liquid layer. As the raw material powder is drawn into the assembly cavity 6, the piston part 5 moves upward and contacts the first pressure sensor 9. Sensor 9 transmits an electrical signal, causing the electric push rod 123 in the actuator 12 to start, pushing the switching assembly 8 upward. The annular groove 82 in the switching assembly 8 moves upward and connects with the spray outlet 7. At the same time, the movable block 81 seals the liquid outlet of the support tube 43. Then, the lifting mechanism 3 starts again, moves downward to reset, and drives the piston 5 to move downward in the assembly cavity 6. The solution containing raw material powder is sprayed through the through hole 84, the annular groove 82 and the spray outlet 7 into the interior of the processing agent inside the processing cylinder 1. It is sprayed out quickly and mixes with the processing agent in the processing cylinder 1. The target component in the raw material powder that is in full contact with the internal filling disturbance is quickly precipitated, completing the extraction. When the piston 5 moves downward and contacts the second pressure sensor 11, it sends an induction electrical signal and controls the electric push rod 123 to move and reset, resealing the spray outlet 7 and opening one end of the support tube 43, waiting for the next suction spray.

[0033] First, by utilizing the floating liquid suction component 4, lifting mechanism 3, execution component 12, piston part 5, and sensing control mechanism, the raw material powder floating on the surface of the treatment agent liquid is sucked in and sprayed after being sucked in together with the treatment agent. By using top suction and internal spraying, the raw material powder is mixed and disturbed, improving the mixing uniformity of the raw material powder, thereby improving the separation and extraction efficiency of the target components. Furthermore, through the cooperation and control of the float 45, as the raw material powder at the top is gradually sucked in, it is kept synchronously lowered with the decrease of the treatment agent liquid level, and the suction treatment of the raw material powder at the top is completed at all times, which greatly improves the suction effect, ensures that the total amount of sprayed raw material powder is sufficient, completes sufficient spray mixing, and greatly improves the actual extraction efficiency.

[0034] Example 2: During the extraction process, the heating tube 133 in the composite processing component 13 is activated, and the air pump 132 is started. The air pump 132 pumps air into the fixed ring 131 and heats it into hot air. The hot air is output upward along the ventilation pipe 134, and heat is exchanged when it passes through the solvent inside the processing cylinder 1. The hot air is further injected into the processing agent through the outlet end of the ventilation pipe 134, which makes the internal temperature of the processing agent high. The target component in the raw material powder is rapidly precipitated after being heated. When the hot air is injected into the processing agent, it impacts the inside of the processing agent, causing the liquid inside the processing agent to flow and complete the disturbance. The raw material powder fully contacts the processing agent and completes the accelerated precipitation. After the extraction is completed and the material is discharged from the outlet, the hot air is kept introduced into the ventilation pipe 134, and the hot air is sprayed into the inside of the processing cylinder 1 through the ventilation pipe 134 to complete the wind-blown drying.

[0035] First, by utilizing the ventilation treatment of the composite treatment component 13, hot air is input. In conjunction with the positioning of the ventilation pipe 134, preliminary heat exchange is achieved during the passage through the treatment agent. After passing through, hot air is directly injected into the interior of the treatment agent in a jet-like manner. The impact and disturbance of the airflow on the interior of the treatment agent further improves the mixing effect of the treatment agent and raw material powder in the treatment cylinder 1, thereby further improving the separation efficiency of the target components in the raw material powder, resulting in good performance.

[0036] Furthermore, by utilizing the aforementioned hot air introduction setting, the interior of the treatment agent is fully heated when injected into the treatment agent, thereby increasing the temperature of the treatment agent and improving the extraction effect of the raw material powder. The overall extraction effect is good. After the extraction is completed and the interior of the treatment cylinder 1 is emptied, hot air is used to blow dry the interior of the treatment cylinder 1 and complete the cleaning process, resulting in good performance.

[0037] The lifting mechanism 3 includes a support frame and an electric push rod 2. The movable end of the electric push rod 2 is fixedly connected to the piston part 5 and controls the piston part 5 to move up and down.

[0038] The piston 5 is moved up and down by using the lifting mechanism 3 to complete the two steps of suction and injection.

[0039] The piston part 5 includes a connecting rod 51 and a piston head 52. The connecting rod 51 is movably sleeved inside the mounting post 2, and one end is fixedly connected to the piston head 52, while the other end is fixedly connected to the movable end of the electric push rod 2. The piston head 52 is movably sleeved in the assembly cavity 6.

[0040] The piston section 5 is used to complete the suction and injection work. The outer side of the piston head 52 is provided with a sealing ring (not shown in the figure) to maintain dynamic sealing. The connecting rod 51 is used to connect and fix with the lifting mechanism 3.

[0041] The switching component 8 includes a movable block 81, an annular groove 82, a sealing ring 83, and a through hole 84. The annular groove 82 is formed on the outer surface of the movable block 81. The sealing ring 83 is fixedly nested on the top of the outer side of the movable block 81. The through hole 84 is formed on the top of the movable block 81 and communicates with the annular groove 82. The nozzle 7 is located on the moving path of the annular groove 82.

[0042] The connection switching is achieved by switching component 8. When it is in the lower position, it ensures that one end of the support tube 43 is connected to the assembly cavity 6 to maintain liquid suction treatment. When it moves upward, it seals one end of the support tube 43 and opens the nozzle 7 to ensure that the liquid sucked in inside can be sprayed out.

[0043] The movable ring 41 is movably sleeved on the outer side of the mounting column 2, the suction frame 44 is symmetrically distributed on both sides of the movable ring 41 and is fixedly connected, and the suction chamber 46 is opened on the upper part of the suction frame 44.

[0044] Liquid is drawn in by using the suction box 44, and the suction chamber 46 is fully connected to the upper liquid surface of the treatment liquid for easy suction.

[0045] The sensing control mechanism includes a first pressure sensor 9, a positioning ring 10, and a second pressure sensor 11. The first pressure sensor 9 is fixed to the top of the assembly cavity 6. The positioning ring 10 is fixedly sleeved in the assembly cavity 6 and located above the suction end of the support tube 43. The second pressure sensor 11 is fixedly nested on the top of the positioning ring 10. The sensing control mechanism contacts and senses the piston part 5 and controls the action of the execution component 12.

[0046] The sensing control mechanism completes combined control through pressure sensor 9 and pressure sensor 11 and an external control terminal. It senses the up and down position of piston 5 and controls the action of actuator 12 to complete the position control of switching component 8. Both pressure sensor 9 and pressure sensor 11 are Honeywell 26PC Series.

[0047] The execution component 12 includes a mounting sleeve 121, a push rod 122, and an electric push rod 123. The mounting sleeve 121 is fixed to the bottom of the processing cylinder 1. The push rod 122 is movably sleeved inside the mounting sleeve 121, and its upper end passes through the processing cylinder 1 and is fixedly connected to the switching component 8. The electric push rod 123 is fixed to the bottom of the mounting sleeve 121, and its movable end is fixedly connected to the push rod 122.

[0048] The movement control of the switching component 8 is achieved by using the up-and-down movement of the actuator 12, the electric push rod 123 provides the actuation power, and the push rod 122 is used to connect the switching component 8.

[0049] The bottom of the processing cylinder 1 is fixedly provided with a composite processing component 13. The composite processing component 13 includes a fixing ring 131, an air pump 132, a heating tube 133, and a ventilation curved pipe 134. The fixing ring 131 is fixedly connected to the bottom of the processing cylinder 1 and is sleeved on the outside of the execution component 12. The air pump 132 is fixed to the bottom of the processing cylinder 1 by a bracket, and the air outlet end of the air pump 132 is connected to the fixing ring 131. The heating tube 133 is fixedly installed in the fixing ring 131. The ventilation curved pipe 134 is fixedly wrapped around the outside of the fixing ring 131 and is fixedly sleeved in the processing cylinder 1. The upper part of the ventilation curved pipe 134 is higher than the liquid level, and the upper air outlet end of the ventilation curved pipe 134 faces downward and is submerged in the liquid.

[0050] By using the composite treatment component 13 to input hot air into the treatment cylinder 1, and guiding the hot air to be injected into the treatment agent after passing through from the inside to the outside, the impact disturbance is completed, thus completing the combined effect of heating treatment and disturbance treatment.

[0051] The working principle and usage process of this invention: During the extraction process, the treatment agent is poured into the treatment cylinder 1, and the raw material powder to be treated is poured into the treatment cylinder 1. Some of the raw material powder floats above the surface of the treatment agent liquid, and the floating liquid suction assembly 4 floats above the liquid surface through the float 45. The lifting mechanism 3 is activated, and the lifting mechanism 3 drives the piston part 5 to move inside the mounting column 2. The upward movement causes the piston part 5 to draw air from the inside of the floating liquid suction assembly 4 through the assembly cavity 6, and to draw liquid above the liquid surface through the liquid suction frame 44. This allows the raw material powder floating on top of the treatment agent to be drawn together with the treatment agent into the connecting pipe 42, and then sucked into the assembly through the support pipe 43. In cavity 6, as the liquid level decreases, the floating liquid suction component 4 gradually lowers accordingly, continuing to draw in the treatment agent and raw material powder above the liquid layer. As the raw material powder is drawn into assembly cavity 6, the piston 5 moves upward and contacts the first pressure sensor 9. The first pressure sensor 9 transmits an electrical signal, causing the electric push rod 123 in the actuator 12 to activate, pushing the switching component 8 upward. The annular groove 82 in the switching component 8 moves upward and connects with the spray outlet 7. At the same time, the movable block 81 seals the liquid outlet of the support tube 43. Subsequently, the lifting mechanism 3 is activated again, moving downward to reset, and driving the piston 5 to move downward in assembly cavity 6, drawing in the solution containing the raw material powder. The treatment agent is injected into the interior of the treatment cylinder 1 through the through hole 84, the annular groove 82, and the nozzle 7. It is rapidly ejected and mixed with the treatment agent in the treatment cylinder 1. The internal filling agitation ensures that the target component in the raw material powder, which is in full contact with it, is rapidly precipitated, completing the extraction. When the piston 5 moves downward and contacts the second pressure sensor 11, it sends an induction electrical signal and controls the electric push rod 123 to move and reset, resealing the nozzle 7 and opening one end of the support tube 43, awaiting the next suction injection. During the extraction process, the heating tube 133 in the composite treatment assembly 13 is activated, and the air pump 132 is started. The air pump 132 pumps air into the fixed ring 131, and... Heating is done with hot air, which is output upwards along the ventilation pipe 134. It exchanges heat as it passes through the solvent inside the processing cylinder 1, and the hot air is further injected into the processing agent through the outlet end of the ventilation pipe 134, which raises the internal temperature of the processing agent. The target components in the raw material powder are rapidly precipitated after being heated. When the hot air is injected into the processing agent, it impacts the inside of the processing agent, causing the liquid inside the processing agent to flow and complete the disturbance. The raw material powder fully contacts the processing agent and completes the accelerated precipitation. After extraction is completed and the material is discharged from the outlet, hot air is kept introduced into the ventilation pipe 134, and the hot air is sprayed into the inside of the processing cylinder 1 through the ventilation pipe 134 to complete the wind-driven drying.
