Abstract
Description
Technical Field
[0001] This utility model relates to the field of cochineal red pigment extraction technology, specifically a device for extracting cochineal red pigment. Background Technology
[0002] Cochineal red is a pigment extracted from the female cochineal insects that parasitize cacti. It is a red pigment obtained by grinding the dried female cochineal insects and extracting them with water. Its main component is cochineal acid, also known as carmine acid, which is an anthraquinone derivative.
[0003] Traditional methods: Currently, the extraction of cochineal red pigment mostly uses static soaking or simple stirred extraction tanks. These methods have some problems: static soaking has a long cycle, and dynamic stirring also requires a long time to achieve a high extraction rate. In addition, it is not possible to perform initial solid-liquid separation on the material after extraction, which increases the workload of subsequent separation. Utility Model Content
[0004] The purpose of this invention is to provide a device for extracting cochineal red pigment, so as to solve the problems mentioned in the background art.
[0005] The technical solution of this utility model is: an extraction device for cochineal red pigment, comprising a temperature-controlled tank, an inlet pipe at the top of the tank, a feed pipe on one side of the bottom of the tank, a drain pipe on one side of the tank, a feeding assembly connected to the bottom of the tank, an adjustable lifting and filtration assembly inside the tank, a stirring mechanism inside the tank, and a circulation assembly for sucking up the extract from the top of the tank, the outlet of the circulation assembly being connected to an annular liquid guiding assembly extending above the lifting and filtration assembly.
[0006] The effects achieved by the above components are as follows: the temperature-controlled tank can precisely control the extraction temperature, providing a suitable environment for pigment extraction; the stirring mechanism stirs the cochineal material and extract in the tank, increasing their contact; the circulation component draws the extract from the top of the tank and sprays it evenly onto the material above the lifting and pressing filter assembly through the annular liquid guiding component, forming an extract circulation, improving the contact efficiency between the material and the extract, and preventing the cochineal powder from clogging the mesh of the lifting and pressing filter assembly during the rinsing process; after extraction, the lifting and pressing filter assembly can be adjusted downwards to press and filter the material, and the drain pipe is used to discharge the extract. The cochineal powder containing a certain amount of moisture after the initial pressing accumulates at the bottom of the tank, and then the feeding component is used to discharge the cochineal powder. The cochineal powder containing some moisture is fluid and easy to discharge completely, achieving the purpose of shortening the extraction cycle and increasing the extraction rate. At the same time, it adds the initial solid-liquid separation function and reduces the amount of subsequent separation work.
[0007] Preferably, the stirring mechanism includes a stirring motor installed on the top of the tank, the output shaft of the stirring motor is fixed with a stirring shaft extending into the interior of the tank, and the bottom end of the stirring shaft is fixed with stirring blades that fit against the inner wall of the bottom end of the tank.
[0008] The aforementioned components achieve the following effects: the stirring motor drives the stirring shaft to rotate, causing the stirring blades to rotate within the tank. The stirring blades adhere closely to the inner wall at the bottom of the tank, ensuring thorough stirring of the cochineal material at the bottom and preventing material sedimentation. This achieves more uniform contact between the material and the extract, improving pigment extraction efficiency and shortening extraction time.
[0009] Preferably, the lifting and filtration assembly includes an electric lifting rod installed at the top of the tank, a lifting frame connected to the bottom end of the electric lifting rod, and a filter screen that fits against the inner wall of the tank connected to the bottom end of the lifting frame.
[0010] The effects achieved by the above components are as follows: the electric lifting rod can drive the lifting frame to adjust the filter screen up and down in the tank. During the extraction process, the filter screen rises to a suitable position without affecting the stirring and circulation. After the extraction is completed, the filter screen descends and fits against the inner wall of the tank to form a pressing space, which presses and filters the material. This achieves the purpose of initial solid-liquid separation of the extracted material, increases the integrated function of the device, and reduces the workload of subsequent separation.
[0011] Preferably, the circulation assembly includes a circulation pump installed on the top of the tank, the inlet end of the circulation pump is connected to a suction pipe extending to the top of the tank, and the outlet end of the circulation pump is connected to a guide pipe of the annular liquid guiding assembly.
[0012] The aforementioned components achieve the following effect: the circulating pump draws the extract from the top of the tank through the suction pipe, and then transports the extract to the annular liquid guiding assembly through the guide pipe, allowing the extract to re-enter the material area. This achieves the recycling of the extract, ensuring repeated contact between the extract and the material, thereby improving the pigment extraction rate and shortening the extraction time.
[0013] Preferably, the annular liquid guiding assembly includes an annular tube installed inside the tank, one side of the annular tube being connected to the guide pipe, and a plurality of annularly distributed nozzles being installed at the bottom end of the annular tube.
[0014] The effect achieved by the above components is as follows: the annular pipe is connected to the guide pipe of the circulation component to receive the circulating extract, and then the extract is evenly sprayed onto the material surface above the lifting and pressing filter component through multiple annularly distributed nozzles, so as to achieve the purpose of uniform contact between the extract and the material, improve the contact area and efficiency between the material and the extract, and thus improve the pigment extraction rate.
[0015] This invention provides an improved device for extracting cochineal red pigment, which has the following improvements and advantages compared with the prior art:
[0016] Firstly, this utility model uses a ring-shaped liquid guiding component to evenly spray the extract into the material above the lifting and pressing filter assembly, forming an extract circulation, which improves the contact efficiency between the material and the extract, and can also prevent cochineal powder from clogging the mesh of the lifting and pressing filter assembly during the rinsing process.
[0017] Secondly, after extraction, the lifting and pressing filter assembly can be adjusted downwards to press and filter the material, and the drain pipe is used to discharge the extract. The cochineal powder containing a certain amount of moisture after initial pressing accumulates at the bottom of the tank. Then, the feeding assembly is used to discharge the cochineal powder. The cochineal powder containing some moisture is fluid and easy to discharge completely, which shortens the extraction cycle and increases the extraction rate. At the same time, it increases the initial solid-liquid separation function and reduces the amount of subsequent separation work. Attached Figure Description

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. 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 protection scope of the present invention.
[0024] This utility model provides an improved device for extracting cochineal red pigment. The technical solution of this utility model is as follows:
[0025] In embodiments of this utility model, such as Figure 1 - Figure 2As shown, an extraction device for cochineal red pigment includes a temperature-controlled tank 1, which can precisely control the extraction temperature and provide a suitable environment for pigment extraction. A liquid inlet pipe 2 is installed at the top of the tank 1, a feed pipe 3 is installed on one side of the bottom of the tank 1, and a drain pipe is installed on one side of the tank 1. A feeding assembly 8 is connected to the bottom of the tank 1. An adjustable lifting and filtering assembly 7 is installed inside the tank 1. After extraction, the lifting and filtering assembly 7 can be adjusted downwards to press and filter the material. The drain pipe discharges the extract. The cochineal powder containing a certain amount of moisture after initial pressing accumulates at the bottom of the tank 1. Then, the feeding assembly 8 discharges the cochineal powder. The partially moist cochineal powder is fluid and easy to discharge completely. A stirring mechanism 4 is installed inside the tank 1, and a stirring device is installed at the top of the tank 1. A circulation assembly 6 is used to draw the extract from the top of the tank 1. The circulation assembly 6 includes a circulation pump installed on the top of the tank 1. The inlet end of the circulation pump is connected to a suction pipe extending to the top of the tank 1. The outlet end of the circulation pump is connected to a guide pipe connected to an annular guide assembly 5. The circulation pump draws the extract from the top of the tank 1 through the suction pipe and then transports the extract to the annular guide assembly 5 through the guide pipe, so that the extract re-enters the material area. The outlet end of the circulation assembly 6 is connected to an annular guide assembly 5 extending above the lifting and pressing filter assembly 7. The circulation assembly 6 draws the extract from the top of the tank 1 and sprays the extract evenly into the material above the lifting and pressing filter assembly 7 through the annular guide assembly 5, forming an extract circulation, improving the contact efficiency between the material and the extract, and also preventing cochineal powder from clogging the mesh of the lifting and pressing filter assembly 7 during the rinsing process.
[0026] In an embodiment of this utility model, the stirring mechanism 4 includes a stirring motor installed on the top of the tank 1. The output shaft of the stirring motor is fixed with a stirring shaft extending into the inside of the tank 1. The bottom end of the stirring shaft is fixed with a stirring blade that fits against the inner wall of the bottom end of the tank 1. The stirring motor drives the stirring shaft to rotate, causing the stirring blade to rotate inside the tank 1. The stirring blade fits against the inner wall of the bottom end of the tank 1, which can fully stir the cochineal material at the bottom of the tank 1 and prevent the material from settling at the bottom of the tank 1.
[0027] In an embodiment of this utility model, the lifting and pressing filter assembly 7 includes an electric lifting rod 71 installed at the top of the tank 1. The bottom end of the electric lifting rod 71 is connected to a lifting frame 72, and the bottom end of the lifting frame 72 is connected to a filter screen 73 that fits against the inner wall of the tank 1. The electric lifting rod 71 can drive the lifting frame 72 to move the filter screen 73 up and down within the tank 1. During the extraction process, the filter screen 73 rises to a suitable position without affecting stirring and circulation. After extraction, the filter screen 73 descends and fits against the inner wall of the tank 1 to form a pressing space, thereby pressing and filtering the material and achieving the purpose of initial solid-liquid separation of the extracted material.
[0028] In an embodiment of this utility model, the annular liquid guiding component 5 includes an annular tube installed inside the tank 1. One side of the annular tube is connected to the guide tube, and a plurality of annularly distributed nozzles are installed at the bottom end of the annular tube. The annular tube is connected to the guide tube of the circulation component 6 to receive the circulating extract. The extract is then evenly sprayed onto the material surface above the lifting and pressing filter component 7 through the plurality of annularly distributed nozzles, thereby achieving the purpose of uniform contact between the extract and the material.
[0029] The working principle of the cochineal red pigment extraction device provided by this utility model is as follows:
[0030] Material and extract addition stage: Cochineal material is added into tank 1 through feed pipe 3, and extract is added through liquid inlet pipe 2. The temperature-controlled tank 1 is adjusted to a suitable extraction temperature to provide a stable environment for pigment extraction.
[0031] Stirring and extraction stage: Stirring mechanism 4 is started, and stirring motor drives stirring shaft to rotate stirring blades. Because stirring blades are in contact with the inner wall of the bottom of tank 1, the material and extract in tank 1 can be fully stirred, avoiding material sedimentation and increasing the contact frequency between the two.
[0032] Circulation enhancement stage: The circulation component 6 works synchronously. The circulation pump draws the extract from the top of the tank 1 through the suction pipe, and delivers it to the annular pipe of the annular liquid guiding component 5 through the guide pipe. Then, the extract is evenly sprayed onto the material above the lifting and pressing filter component 7 through the annularly distributed nozzles, forming an extract circulation, so that the material and the extract are repeatedly in contact, improving the extraction efficiency.
[0033] Solid-liquid separation stage: After extraction, the electric lifting rod 71 of the lifting and pressing filter assembly 7 drives the lifting frame 72 to lower the filter screen 73. The filter screen 73 fits against the inner wall of the tank 1 to form a pressing space, pressing and filtering the material to achieve initial solid-liquid separation. The separated liquid can be discharged through the drain pipe, and the residue is processed through the feeding assembly 8.
