Description

Technical Field

[0001] This utility model relates to the field of biochemical technology, and in particular to a dynamic countercurrent extraction unit system for the production and extraction of coenzyme Q10. Background Technology

[0002] Coenzyme Q10 is an important substance widely used in pharmaceuticals, cosmetics, and food additives. It possesses various physiological activities, including antioxidant activity, immune enhancement, and improvement of heart function. In the production of coenzyme Q10, the extraction process is one of the key steps, as its efficiency and purity directly affect the quality and cost of the final product. Traditional extraction methods involve adding a washing solution and Q10 sludge to a stirred tank, mixing for an extended period, and then extracting the washing solution containing Q10 for purification. Except for the stirring process, everything is manually controlled, resulting in low extraction efficiency, high solvent consumption, and long production cycles. Therefore, developing a highly efficient, energy-saving, and environmentally friendly extraction method is particularly important. Utility Model Content

[0003] In view of this, the present invention provides a dynamic countercurrent extraction unit for the coenzyme Q10 production extraction process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A dynamic countercurrent extraction unit system for coenzyme Q10 production includes an extractor and a slag remover. Multiple extractors are provided and connected sequentially. Each extractor has an inlet at its front top for adding Q10 sludge and a slag remover at its rear end. The head and tail ends have connecting ports for introducing cleaning solution. The head port of the current extractor is connected to the tail port of the previous extractor, and the tail port of the current extractor is connected to the head port of the next extractor.

[0006] The slag removal machine is provided in multiple sets, and the slag removal machine corresponds to the extractor one by one. It is used to send the residue at the tail of the lower extractor to the feed port of the next stage extractor. The slag removal machine is installed at the slag removal port of the corresponding extractor.

[0007] The slag remover corresponding to the final stage extractor transports the residue to the slag extruder; the liquid outlet of the slag extruder is connected to the tail end of the final stage extractor through a return liquid pipe; the head end of the first stage extractor is connected to the extractant tank through a liquid delivery pipe.

[0008] The extraction tank is equipped with two pipelines; one pipeline is located at the bottom and leads to the slag removal port of the first-stage extractor; the other pipeline is located at the top of the extraction tank and is used to collect the supernatant and transport the supernatant to the next process.

[0009] Furthermore, the cleaning fluid is n-hexane, which is input from the tail end of the final stage extractor, moves in the opposite direction to the residue, and flows into the extraction liquid tank from the head end of the first stage extractor.

[0010] Furthermore, both the slag remover and the extractor are equipped with at least three sets.

[0011] Furthermore, the extraction tank is equipped with a partition to divide the interior of the extraction tank into two chambers, left and right; the partition extends upward from the bottom of the extraction tank and is equipped with a filter screen; the end of the infusion pipeline and the bottom pipeline in the extraction tank are located in the same chamber; the pipeline for taking the supernatant in the extraction tank is located in the other chamber.

[0012] The supernatant flows from one chamber to another through a filter screen.

[0013] The beneficial effects of adopting the above technical solution in this utility model are as follows:

[0014] 1. Improved extraction efficiency: By using countercurrent extraction, the raw materials and extraction solvent can be in more complete contact, thereby improving extraction efficiency.

[0015] 2. Solvent saving: Due to the use of continuous countercurrent extraction, the amount of solvent used is reduced, thus lowering production costs.

[0016] 3. Shortened production cycle: The dynamic countercurrent extraction unit can work continuously, which greatly shortens the production cycle and improves production efficiency.

[0017] 4. Environmental protection and energy saving: This device is reasonably designed, has low energy consumption, and meets the requirements of current green production.

[0018] 5. The presence of a triple slag remover and a single slag squeezer ensures more thorough extraction of Coenzyme Q10 residue.

[0019] In summary, the dynamic countercurrent extraction unit provided by this utility model not only improves the extraction efficiency and purity of coenzyme Q10, but also reduces production costs and shortens the production cycle, resulting in significant economic and social benefits.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0024] Reference Figure 1 In this embodiment, both the extractor 1 and the slag remover 2 are provided with three sets;

[0025] The extractor 1 has an inlet for adding Q10 mud at the top front end and a slag removal port at the rear end; the head and tail ends have connecting ports for introducing washing liquid; it has a two-way auger structure inside for squeezing and transporting the residue of Q10 mud and accumulating the residue at the tail end of the current extractor 1.

[0026] The head port of the intermediate stage extractor 1 is connected to the tail port of the first stage extractor 1, and the tail port of the intermediate stage extractor 1 is connected to the head port of the final stage extractor 1; the ports of adjacent extractors 1 are connected through the cleaning fluid connection pipe 3.

[0027] Reference Figure 2 The main body of the slag removal machine 2 is a conveyor belt structure 12, on which multiple water-leaking baskets 11 are provided; the conveyor belt moves to drive the water-leaking baskets 11 to transport the residue at the tail of the extractor 1 to the next stage extractor 1; this part of the structural features is common knowledge and there are many ways to implement it, so it will not be described in detail.

[0028] The slag removal machine 2 is provided in multiple sets, and the slag removal machine 2 corresponds one-to-one with the extractor 1. It is used to send the residue at the tail of the lower extractor 1 to the feed port of the next stage extractor 1. The slag removal machine 2 is installed at the slag removal port of the corresponding extractor 1.

[0029] The slag remover 2 corresponding to the final stage extractor 1 transports the residue to the slag extruder 5; the outlet of the slag extruder 5 is connected to the tail end of the final stage extractor 1 through the return pipe 4; the head end of the first stage extractor 1 is connected to the extract tank 7 through the delivery pipe 8; a filter 10 can be installed at the inlet end of the delivery pipe to filter out the residue.

[0030] The slag squeezer 5 is used to squeeze out the final residue to extract the leachate, but since the Q10 content in the leachate is low, it is reused through the return pipe 4.

[0031] The extraction tank 7 is equipped with two pipelines; one pipeline is connected to its bottom and transports the liquid to the slag removal port of the first-stage extractor 1; the other pipeline is connected to the top of the extraction tank 7 and is used to collect the supernatant and transport the supernatant to the next process.

[0032] The cleaning solution is n-hexane, which is input from the tail end of the final stage extractor 1 and moves in the opposite direction to the residue. It flows into the extraction liquid tank 7 from the head end of the first stage extractor 1.

[0033] The extraction tank 7 is equipped with a partition to divide the interior of the extraction tank 7 into two chambers, left and right. The partition extends upward from the bottom of the extraction tank 7 and has a filter screen to facilitate the flow of supernatant. The end of the infusion pipe 8 and the bottom pipe in the extraction tank 7 are located in the left chamber. The pipe for taking supernatant in the extraction tank 7 is located in the right chamber.

[0034] A pump is installed in each liquid pipeline to provide power for liquid transfer. When excessive impurities are found in the left chamber, the pump in recovery pipeline 9 is activated to recover the excess impurities at the bottom and transport them to the tail slag removal port of the first-stage extractor 1 for further purification. The washing solution is n-hexane, which is input from the tail connection port of the last-stage extractor 1, moves in the opposite direction to the residue, and flows into the extraction liquid tank 7 from the head connection port of the first-stage extractor 1.

[0035] In this embodiment, both the extractor 1 and the sludge extruder 5 are purchased products. The sludge extruder 5 uses pressure to press the residue and drain the liquid, and there are many products to choose from. The basic working principle of the extractor 1 is as follows: To specifically adapt to the extraction of coenzyme Q10, its length is set at 40m. In the extractor 1, the Q10 sludge inside is transported to the end position through two screw conveyors. A sludge removal port is opened at the end position of the extractor 1. The Q10 is squeezed out from the sludge removal port by the screw conveyors at the end. The drain basket 11 of the sludge removal machine 2 collects and transports the sludge at the sludge removal port. Therefore, the position of the sludge removal port does not necessarily have to be strictly located below the extractor 1. For the specific structure of the extractor 1, please refer to patent ZL201420560408.X.
