Description

Technical Field

[0001] This invention relates to the field of emulsion production technology, and specifically to an apparatus and method for producing emulsions by multiple homogenizations using a single homogenizer. Background Technology

[0002] Fat emulsions are homogeneous and stable emulsions composed of refined oils emulsified with refined lecithin. Their therapeutic importance lies in providing high energy outside the digestive tract. Physiological and nutritional studies have proven that ingested fats are first absorbed by the gastrointestinal tract to form chylomicrons, and the form and composition of this product are extremely similar to chylomicrons. Direct intravenous infusion into patients who cannot eat can provide nutritional support.

[0003] The treatment of fat emulsion tail liquid is a key technology in the emulsification and homogenization process. Existing technologies usually involve using multiple homogenizers in series for multiple homogenization processes to improve the treatment effect. However, this method has the problems of low homogenization efficiency and low production efficiency. At the same time, the use of multiple homogenizers not only increases the space occupied by the equipment, but also greatly increases the production cost. Summary of the Invention

[0004] This invention aims to solve the technical problems of low homogenization efficiency, low production efficiency, and high cost in existing emulsion production. The purpose is to provide an apparatus and method for producing emulsions by homogenizing multiple times with a single homogenizer. One homogenizer can achieve the same emulsion particle effect as multiple homogenizers connected in series, reducing costs while ensuring homogenization effect. The homogenizer can operate without stopping, maximizing the efficiency of emulsion production.

[0005] This invention is achieved through the following technical solution:

[0006] This invention provides an apparatus for producing emulsions by multiple homogenizations using a single homogenizer, comprising: a primary emulsion tank, a third transfer pump, a homogenizer, a first homogenizing tank, a second homogenizing tank, a third homogenizing tank, and a filling tank.

[0007] The inlet of the colostrum tank is connected to the raw material feeding system, and the outlet of the colostrum tank is connected to the inlet of the homogenizer through a circulation main pipe. A conveying pump is installed on the circulation main pipe. The outlet of the homogenizer is connected to the inlet of the colostrum tank through a circulation main pipe to form a first circulation loop.

[0008] Homogenizing tank 1, homogenizing tank 2 and homogenizing tank 3 are connected in parallel between circulation main pipe 1 and circulation main pipe 2. Homogenizing tank 1, homogenizing tank 2 and homogenizing tank 3 are each connected to conveying pump 3 and homogenizer, forming a second circulation loop, a third circulation loop and a fourth circulation loop respectively.

[0009] The homogenizer's discharge end is also connected to the filling tank.

[0010] This invention utilizes a single homogenizer and multiple homogenizing tanks connected in parallel. The emulsion can be sequentially fed into different homogenizing tanks through the single homogenizer for multiple homogenizations, achieving a similar emulsion particle effect as multiple homogenizers connected in series without requiring additional homogenizers. Furthermore, all homogenizing tanks in this invention are connected to the homogenizer, forming a corresponding circulation loop. This ensures that the emulsion is processed by the homogenizer after each homogenization, allowing the homogenizer to operate continuously and maximizing emulsion production efficiency. The invention uses three homogenizing tanks to guarantee highly efficient homogenization. When production demand is low, the homogenizing tanks can operate in a cyclical manner, achieving efficient cyclical homogenization with only three tanks. As demand increases, the number of homogenizing tanks can be adaptively increased.

[0011] Furthermore, the raw material feeding system includes a raw material tank 1, a transfer pump 1, a raw material tank 2, and a transfer pump 2. The raw materials in the raw material tank 1 are fed into the colostrum tank by the transfer pump 1, and the raw materials in the raw material tank 2 are fed into the colostrum tank by the transfer pump 2.

[0012] Furthermore, the raw material tank 1 and the colostrum tank are connected by a feeding pipe 1, the conveying pump 1 is installed on the feeding pipe 1, and the feeding pipe 1 is equipped with a feeding valve 1 and a feeding valve 2; the raw material tank 2 and the colostrum tank are connected by a feeding pipe 2, the conveying pump 2 is installed on the feeding pipe 2, and the feeding pipe 2 is equipped with a feeding valve 3 and a feeding valve 4.

[0013] Furthermore, the colostrum tank, homogenizing tank one, homogenizing tank two, homogenizing tank three, and filling tank are all connected to nitrogen inlet pipes, and nitrogen inlet pipes are equipped with inlet control valves.

[0014] Furthermore, the feed ends of homogenizing tank 1, homogenizing tank 2, and homogenizing tank 3 are respectively connected to the circulation main pipe 2 through feed branch pipe 1, feed branch pipe 2, and feed branch pipe 3, and the discharge ends of homogenizing tank 1, homogenizing tank 2, and homogenizing tank 3 are respectively connected to the circulation main pipe 1 through discharge branch pipe 1, discharge branch pipe 2, and discharge branch pipe 3.

[0015] Furthermore, the feed ends of homogenizing tank 1, homogenizing tank 2 and homogenizing tank 3 are respectively connected to nitrogen blowing pipe 1, nitrogen blowing pipe 2, nitrogen blowing pipe 3 and circulation main pipe 1, and nitrogen blowing valve 1, nitrogen blowing valve 2 and nitrogen blowing valve 3 are respectively installed on nitrogen blowing pipe 1, nitrogen blowing pipe 2 and nitrogen blowing pipe 3.

[0016] Furthermore, the bottom of the homogenizing tank three is connected to the feed end of the filling tank via a nitrogen blowing pipe four, and a nitrogen blowing valve four is provided on the nitrogen blowing pipe four.

[0017] Furthermore, the homogenizer's discharge end is connected to a filling pipe, which is connected to the inlet end of multiple filling tanks through multiple filling branch pipes.

[0018] The present invention also provides a method for producing emulsions by multiple homogenizations using a single homogenizer, based on the aforementioned apparatus, comprising the following steps:

[0019] The colostrum is pumped into a homogenizer, and the first homogenization is carried out between the colostrum tank, the transfer pump, and the homogenizer.

[0020] After the first homogenization, the emulsion is transferred to homogenizing tank 1 via transfer pump 3 and homogenizer. When a certain amount of emulsion remains in the primary emulsion tank, a self-circulation is formed between the primary emulsion tank, transfer pump 3 and homogenizer.

[0021] The emulsion in homogenizing tank 1 is transferred to homogenizing tank 2 via transfer pump 3 and homogenizer to achieve a second homogenization. At the same time as the second homogenization, the emulsion in the primary emulsion tank is blown into homogenizing tank 1 by nitrogen gas. When a certain amount of emulsion remains in homogenizing tank 1, a self-circulation is formed between homogenizing tank 1, transfer pump 3 and homogenizer.

[0022] The emulsion in homogenizing tank 2 is transferred to homogenizing tank 3 for a third homogenization. At the same time, the emulsion in homogenizing tank 1 is blown into homogenizing tank 2 by nitrogen. When a certain amount of emulsion remains in homogenizing tank 2, a self-circulation is formed between homogenizing tank 2, transfer pump 3 and homogenizer.

[0023] Finally, the emulsion in homogenizing tank two is blown into homogenizing tank three, and the emulsion in homogenizing tank three is pumped into the filling tank to complete homogenization.

[0024] This invention first uses a colostrum tank to pre-emulsify the raw materials. Then, the colostrum and a homogenizer form a circulation loop for the first homogenization. The homogenized emulsion from the first homogenization is then transferred to homogenization tank one. Not all the emulsion in the colostrum tank is transferred; the remaining amount is set so that air cannot enter the pipeline. The remaining emulsion in the colostrum tank is then recirculated for further homogenization. Next, the emulsion in homogenization tank one is transferred to homogenization tank two. Simultaneously, the remaining emulsion in the colostrum tank is also blown into homogenization tank one with nitrogen to mix with the emulsion there. The nitrogen blowing allows the emulsion to proceed to the next homogenization tank. Container transfer reduces emulsion residue. Similarly, a certain amount of emulsion must be retained in homogenizing tank one to prevent air from entering the pipes and to allow for self-circulation for further homogenization. The same operation is then performed to transfer the emulsion to the next container. Each transfer passes through the homogenizer, achieving one homogenization cycle. By switching between several homogenizing tanks, the number of homogenization cycles can be selected as needed. The homogenizer operates continuously, ensuring homogenization effectiveness while increasing its utilization rate. This achieves the homogenization effect of one homogenizer equivalent to multiple homogenizers connected in series, effectively improving the production efficiency of the emulsion.

[0025] Furthermore, depending on the production and quality requirements, the number of homogenizing tanks can be increased to increase the number of homogenization cycles. Alternatively, after the third homogenization, the emulsion from the fourth homogenization can be transferred to homogenizing tank one, and then the emulsion from the fifth and sixth homogenization cycles can be transferred to homogenizing tank two and homogenizing tank three in sequence.

[0026] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0027] 1. This invention uses a homogenizer and multiple homogenizing tanks connected in parallel. The emulsion can be homogenized multiple times by sequentially entering different homogenizing tanks through a single homogenizer. This achieves the same emulsion particle effect as multiple homogenizers connected in series without the need for more homogenizers, thus reducing costs while ensuring homogenization effect.

[0028] 2. In this invention, all homogenizing tanks are connected to the homogenizer to form a corresponding circulation loop. In this way, each homogenized emulsion needs to be processed by the homogenizer, so that the homogenizer can work continuously without stopping, thereby improving the utilization rate of the homogenizer and maximizing the emulsion production efficiency.

[0029] 3. In this invention, during homogenization, the emulsion after each homogenization is transferred to the next homogenization tank, and a certain amount is retained during the transfer to prevent air from entering the pipeline and damaging the equipment.

[0030] 4. In the process of homogenization, the present invention can transfer the emulsion to the next homogenizing tank by blowing nitrogen gas, thereby reducing emulsion transfer residue. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0036] Example 1

[0037] This embodiment provides an apparatus for producing emulsions by multiple homogenizations using a single homogenizer, including: a primary emulsion tank 6, a transfer pump 3 14, a homogenizer 15, a homogenizing tank 17, a homogenizing tank 2 18, a homogenizing tank 3 19, and a filling tank 52.

[0038] The inlet of the colostrum tank 6 is connected to the raw material feeding system, and the outlet of the colostrum tank 6 is connected to the inlet of the homogenizer 15 through the first circulation pipe 13. The third conveying pump 14 is installed on the first circulation pipe 13, and the outlet of the homogenizer 15 is connected to the inlet of the colostrum tank 6 through the second circulation pipe 16 to form a first circulation loop.

[0039] The homogenizing tank 17, homogenizing tank 28 and homogenizing tank 319 are connected in parallel between the circulation main pipe 13 and the circulation main pipe 26. The homogenizing tank 17, homogenizing tank 28 and homogenizing tank 319 are each connected to the transfer pump 314 and the homogenizer 15, forming the second circulation loop, the third circulation loop and the fourth circulation loop respectively.

[0040] The discharge end of the homogenizer 15 is also connected to the filling tank 52.

[0041] This invention utilizes a single homogenizer 15 and multiple homogenizing tanks connected in parallel. The emulsion can be circulated multiple times between different homogenizing tanks via the single homogenizer 15, achieving a multi-stage homogenization effect without requiring additional homogenizers 15 to achieve the same emulsion particle effect as multiple homogenizers connected in series. Furthermore, all homogenizing tanks in this invention are connected to the homogenizer 15, forming their own circulation loops. This ensures that the emulsion is processed by the homogenizer 15 each time it is homogenized, allowing the homogenizer 15 to operate continuously and maximizing emulsion production efficiency. The invention uses three homogenizing tanks to ensure highly efficient homogenization. When production demand is low, the homogenizing tanks can operate in a cyclical manner, achieving efficient cyclical homogenization with only three tanks. As demand increases, the number of homogenizing tanks can be adaptively increased.

[0042] The raw material feeding system includes raw material tank 1, conveying pump 2, raw material tank 7, and conveying pump 10.

[0043] The raw material tank 1 contains glycerol or other water-soluble materials. The raw material tank 1 is connected to the colostrum tank 6 via a feeding pipe 4. A conveying pump 2 is installed on the feeding pipe 4 to pump the raw materials into the colostrum tank 6. The feeding pipe 4 is equipped with a feeding valve 3 and a feeding valve 5. Specifically, the feeding valve 3 is located between the raw material tank 1 and the conveying pump 2, and the feeding valve 5 is located between the conveying pump 2 and the colostrum tank 6. The amount of glycerol or other water-soluble materials added is controlled by the feeding valves 3 and 5. After the glycerol or other water-soluble materials are transferred to the colostrum tank 6, the water used to wash the raw material tank 1 is also transferred to the colostrum tank 6. Water is added to the colostrum tank 6 to the set volume of the aqueous phase.

[0044] The raw materials in the second raw material tank 7 are soybean oil and other oily and oil-soluble substances. After heating, lecithin and other emulsifiers are added. The second raw material tank 7 is connected to the primary emulsion tank 6 through a second feeding pipe 9. A second conveying pump 10 is installed on the second feeding pipe 9 to pump the raw materials into the primary emulsion tank 6. The second feeding pipe 9 is equipped with a third feeding valve 11 and a fourth feeding valve 12. Specifically, the third feeding valve 11 is located between the second raw material tank 7 and the first conveying pump 2, and the fourth feeding valve 12 is located between the second conveying pump 10 and the primary emulsion tank 6. The amount of oily materials and other raw materials added is controlled by the third feeding valve 11 and the fourth feeding valve 12. After the soybean oil and other oily and oil-soluble substances are transferred to the primary emulsion tank 6, they are emulsified under the high-speed stirring of the stirring device 8 in the primary emulsion tank 6.

[0045] The primary emulsion tank 6, homogenizing tank 17, homogenizing tank 2 18, homogenizing tank 3 19, and filling tank 52 are all connected to nitrogen inlet pipes 40, and each nitrogen inlet pipe 40 is equipped with an inlet control valve. The purpose of the nitrogen inlet pipes 40 is to provide power for emulsion transfer, allowing nitrogen to blow the emulsion into the next container.

[0046] The feed ends of homogenizing tank 17, homogenizing tank 2 18, and homogenizing tank 3 19 are connected to the circulation main pipe 2 16 through feed branch pipe 1 43, feed branch pipe 2 45, and feed branch pipe 3 47, respectively. The discharge ends of homogenizing tank 17, homogenizing tank 2 18, and homogenizing tank 3 19 are connected to the circulation main pipe 13 through discharge branch pipe 1 22, discharge branch pipe 2 28, and discharge branch pipe 3 35, respectively.

[0047] Specifically, the circulation main pipe 13 is equipped with a circulation control valve 41 at the discharge end of the primary emulsion tank 6, a circulation control valve 24 at the circulation main pipe 13 between the primary emulsion tank 6 and the homogenizing tank 17, a circulation control valve 25 and a circulation control valve 30 at the circulation main pipe 13 between the homogenizing tank 17 and the homogenizing tank 28, a circulation control valve 31 and a circulation control valve 34 at the circulation main pipe 13 between the homogenizing tank 28 and the homogenizing tank 39, a circulation control valve 37 at the homogenizing tank 39 and the transfer pump 314, and a feed valve 42 at the feed end of the primary emulsion tank 6.

[0048] Specifically, feed valve 24, feed valve 36, and feed valve 48 are respectively installed on feed branch pipe 1 43, feed branch pipe 2 45, and feed branch pipe 3 47; and discharge valve 1 23, discharge valve 29, and discharge valve 36 are respectively installed on discharge branch pipe 1 22, discharge branch pipe 2 28, and discharge branch pipe 3 35.

[0049] By setting up homogenizer 17, homogenizer 28, and homogenizer 39 in parallel with colostrum tank 6, they can form their own independent circulation paths and perform multiple homogenizations. The opening and closing of different circulation loops can be controlled by setting each valve.

[0050] The feed ends of homogenizing tank 17, homogenizing tank 28, and homogenizing tank 39 are connected to the circulation main pipe 13 via nitrogen blowing pipe 120, nitrogen blowing pipe 26, nitrogen blowing pipe 32, and circulation main pipe 13, respectively. Nitrogen blowing pipe 120, nitrogen blowing pipe 26, and nitrogen blowing pipe 32 are respectively equipped with nitrogen blowing valve 121, nitrogen blowing valve 27, and nitrogen blowing valve 33. By using these nitrogen blowing pipes, nitrogen gas is used to blow the emulsion into the next container, preventing emulsion transfer and residue.

[0051] The bottom of the homogenizing tank 19 is connected to the inlet of the filling tank 52 via a nitrogen blowing pipe 38, and a nitrogen blowing valve 39 is installed on the nitrogen blowing pipe 38. Finally, the emulsion in the homogenizing tank 19 enters the filling tank 52 for filling, and any remaining emulsion is blown into the filling tank 52 through the nitrogen blowing pipe 38 to reduce emulsion residue.

[0052] The homogenizer 15 has a filling pipe 49 connected to its discharge end. This filling pipe 49 is connected to the inlet ends of multiple filling tanks 52 via multiple filling branch pipes 50. Figure 1 As shown, multiple filling tanks 52 can be set up as needed. The feed end of each filling tank 52 is connected to a filling branch pipe 50. The homogenized emulsion enters the corresponding filling tank 52 sequentially through the filling pipe 49 and the filling branch pipe 50.

[0053] Example 2

[0054] This embodiment provides a method for producing emulsions through multiple homogenizations using a single homogenizer, including the following steps:

[0055] (1) After transferring the glycerol or other water-soluble materials in raw material tank 1 to the colostrum tank 6, the water used to wash raw material tank 1 is also transferred to the colostrum tank 6. Water is added to the colostrum tank 6 to the set volume of the aqueous phase. Then, the soybean oil and other oily and oil-soluble substances in raw material tank 27 are transferred to the colostrum tank 6 to form an emulsion under the high-speed stirring of the pump in the colostrum tank 6.

[0056] (2) Open all valves on the main circulation pipe 13 and the feed valve 42 of the primary emulsion tank 6 to perform the first homogenization between the primary emulsion tank 6, the transfer pump 14, and the homogenizer 15. After the pressure stabilizes, proceed to the next step.

[0057] (3) Close the feed valve 42 of the primary emulsion tank 6 and open the feed valve 44 of the homogenizing tank 17 so that the emulsion after the first homogenization is transferred to the homogenizing tank 17 through the transfer pump 14 and the homogenizer 15. When a certain amount of emulsion remains in the primary emulsion tank 6, open the feed valve 42 of the primary emulsion tank 6 and close the feed valve 44 of the homogenizing tank 17 to form a self-circulation between the primary emulsion tank 6, the transfer pump 14 and the homogenizer 15.

[0058] (4) After a certain period of time (related to the processing capacity and remaining amount of homogenizer 15), open the discharge valve 23 of homogenizer 17 and the feed valve 46 of homogenizer 28, and transfer the emulsion in homogenizer 17 to homogenizer 28 through pump 3 14 and homogenizer 15 to complete the second homogenization. At the same time as the second homogenization, the emulsion in primary emulsion tank 6 is blown into homogenizer 17 through nitrogen. When a certain amount of emulsion remains in homogenizer 17, open feed valve 44 of homogenizer 17 and close feed valve 46 of homogenizer 28, forming a self-circulation between homogenizer 17, pump 3 14 and homogenizer 15.

[0059] (5) After a certain period of time (consistent with the self-circulation time of the primary emulsion tank 6), open the discharge valve 29 of the homogenizing tank 2 18 and the feed valve 48 of the homogenizing tank 3 19 to transfer the emulsion in the homogenizing tank 2 18 to the homogenizing tank 3 19 to complete the third homogenization. At the same time, the emulsion in the homogenizing tank 1 17 is blown into the homogenizing tank 2 18 through nitrogen. When a certain amount of emulsion remains in the homogenizing tank 2 18, open the feed valve 46 of the homogenizing tank 2 18 and close the feed valve 48 of the homogenizing tank 3 19 to form a self-circulation between the homogenizing tank 2 18, the transfer pump 3 14 and the homogenizer 15.

[0060] (6) Finally, the emulsion in homogenizing tank 2 18 is blown into homogenizing tank 3 19, and at the same time, the emulsion in homogenizing tank 3 19 is pumped into filling tank 52 to complete homogenization.

[0061] This invention first uses a primary emulsion tank 6 to pre-emulsify the raw materials. Then, the primary emulsion and homogenizer 15 form a circulation loop for the first homogenization. The homogenized emulsion from the primary emulsion tank 6 is then transferred to homogenization tank 17. The remaining emulsion in the primary emulsion tank 6 is not completely transferred; the remaining amount is set to prevent air from entering the pipeline. The remaining emulsion in the primary emulsion tank 6 is then recirculated for further homogenization. Next, the emulsion in homogenization tank 17 is transferred to homogenization tank 28. Simultaneously, the remaining emulsion in the primary emulsion tank 6 is also blown into homogenization tank 17 with nitrogen to mix with the emulsion in homogenization tank 17. The nitrogen blowing can direct the emulsion towards… The next container is transferred to reduce emulsion residue. Similarly, a certain amount of emulsion must be retained in homogenizing tank 17 to prevent air from entering the pipes and to allow for self-circulation and further homogenization. The same operation is followed to transfer the emulsion to the next container. Each transfer passes through homogenizer 15, achieving one homogenization cycle. By switching between several homogenizing tanks, the number of homogenization cycles can be selected as needed. Homogenizer 15 operates continuously, ensuring homogenization effect while increasing its utilization rate. One homogenizer 15 achieves the homogenization effect of multiple homogenizers connected in series, effectively improving the production efficiency of the emulsion.

[0062] According to the production and quality requirements, the number of homogenizing tanks can be increased to increase the number of homogenization cycles. The homogenization method remains the same until the final homogenization is completed. After the final homogenization, the feed valve on the last homogenizing tank is closed, and the emulsion is transferred to the filling tank 52 for filling. If there is a pressure change before or after entering the next homogenizing tank, the pressure can be adjusted to a self-circulation mode before entering the next homogenizing tank. Once the pressure stabilizes, the liquid can be transferred to the next homogenizing tank to complete the homogenization of the liquid.

[0063] If the production volume requirement is not high, there is no need to add a homogenizing tank. After the third homogenization, the drug solution can be transferred to homogenizing tank 1 (17) for the fourth homogenization, then to homogenizing tank 2 (18) for the fifth homogenization, then to homogenizing tank 3 (19) for the sixth homogenization, and finally to filling tank 52 for the last homogenization.

[0064] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
