Description

Technical Field

[0001] This utility model relates to the field of high-concentration collagen technology, specifically a membrane system for high-concentration collagen. Background Technology

[0002] Collagen peptides are small-molecule peptide products processed from fresh bones of cattle and sheep using modern biological methods and enzymatic hydrolysis technology. The finished product is a slightly yellow or white powder, easily hygroscopic, readily soluble in water and ethanol, and becomes clear and transparent without precipitation after dissolution. Its molecular weight ranges from 156 to 17813 Daltons, with 88.16% having a molecular weight between 156 and 2984 Daltons. It has a slightly bitter and fishy taste. It is both a health supplement and a widely used raw material for health supplements.

[0003] Studies have shown that polypeptides, especially small molecule peptides, can be directly absorbed through the digestive tract with an absorption rate of almost 100%, and can directly act on human cells. Collagen polypeptides are functional peptides that, in addition to their protein nutritional function, also have very important physiological regulatory functions in the human body, involving most physiological functions such as the nervous system, digestion, absorption, immunity, metabolism, and growth. Collagen polypeptides are important life substances; an intake of about 50g per day can promote physical health, regulate immunity, and delay aging. Currently, functional peptides are recognized domestically and internationally as products with truly physiologically active health benefits. They have been widely available in foreign markets for many years and are considered a "new favorite" in health foods.

[0004] Existing high-concentration collagen processing technology results in a darker color in the concentrated product, and also consumes a significant amount of energy, leading to higher costs. Utility Model Content

[0005] This invention provides a membrane system for high-concentration of collagen, which solves the problems mentioned in the background art.

[0006] This utility model provides the following technical solution: a membrane system for high-concentration collagen, comprising: a feed pump, a filter, a heat exchanger, a high-pressure pump, a membrane module, and a control cabinet. The feed pump is located at the system inlet, feeds material to the filter and provides the pressure required for the filter to operate. The filter traps insoluble substances in the material. The heat exchanger cools the material so that the material temperature meets the requirements of the membrane module. The high-pressure pump provides driving pressure to the membrane module and transports the material to the membrane module. The membrane module separates dissolved substances or microparticles in the material using membrane technology and outputs the material. The control cabinet controls the automated operation of other components of the system and stores relevant operating data to achieve traceability of production data. After operational testing, the entire concentration process of the system is heat-free and without phase change, and can be completed at room temperature. During the concentration process, water in the collagen solution permeates through the membrane under pressure, while collagen is retained by the membrane, thus achieving the purpose of concentration. It realizes the concentration of collagen solution to a high concentration that has never been achieved in the industry using a membrane system. The equipment operating cost is about 10-15 yuan / ton, which saves more than 90% compared to the cost of existing concentrations of more than 200 yuan / ton. The equipment adopts a continuous concentration method, and it only takes ten to twenty minutes from the material entering the system to the finished product.

[0007] As an optional solution for the membrane system for high-concentration collagen described in this utility model, the following features are provided: the pressure of the feed pump is controlled at 2-6 bar to provide a suitable feed pressure for the system and ensure the normal entry of materials into the system; the filter is a security filter with a rejection accuracy of 1-50 μm to protect the high-pressure pump and membrane elements; the heat exchanger is a shell-and-tube heat exchanger to cool materials whose temperature exceeds the membrane element's tolerance range, ensuring that the material temperature meets the membrane element's requirements; the head of the high-pressure pump is 600-800 m; a circulation pump is connected to the inlet and outlet of the membrane module to provide cross-flow to the surface of the membrane module, making it difficult for contaminants to deposit on the membrane module; the maximum operating pressure of this system can reach 80 Bar; the main body of the system equipment and the parts in contact with the liquid, except for the membrane, are made of stainless steel and then welded using argon arc welding, ensuring that the welding points are free of dead corners and reducing pollution during production.

[0008] As an optional solution for the membrane system for high-concentration of collagen described in this utility model, the membrane elements in the membrane module are spiral wound membrane elements, hygienic membrane elements, high-temperature resistant membranes, or highly sterile membranes. The spiral wound membrane elements are nanofiltration or reverse osmosis membranes. The hygienic membrane elements can be cleaned without dead angles during each chemical cleaning. The high-temperature resistant membranes can operate at temperatures below 70°C for a long time. The highly sterile membranes can be periodically sterilized at high temperatures of 80-85°C, reducing the risk of microbial contamination in the system.

[0009] This utility model has the following beneficial effects:

[0010] 1. This membrane system for high-concentration collagen does not require heating or phase change during the entire concentration process and can be operated at room temperature. During the concentration process, water in the collagen solution permeates through the membrane under pressure, while collagen is retained by the membrane, thus achieving the purpose of concentration. It enables the collagen solution to be concentrated to a high concentration that has never been achieved in the industry before. The equipment operating cost is about 10-15 yuan / ton, which saves more than 90% compared to the cost of existing concentrations of more than 200 yuan / ton. The equipment adopts a continuous concentration method, and it only takes ten to twenty minutes from the material entering the system to the finished product.

[0011] 2. Taking nanofiltration concentrate equipment as an example, this membrane system for high-concentration collagen concentrate aims to concentrate the collagen content in the nanofiltration concentrate from 250g / L to 450-500g / L, achieving a suitable concentration for spray drying. This is the first time in China that a membrane system has been used to concentrate collagen solution to such a high concentration. The equipment operating cost is approximately 10-15 RMB / ton, achieving energy savings of over 90% compared to the cost of over 200 RMB / ton for scraper concentrate. The equipment uses a continuous concentration method, with the feed solution taking only ten to twenty minutes from entering the system to the finished product. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Regarding the main applications of membrane separation technology in collagen peptide production: The application of a high-concentration membrane system can further concentrate nanofiltration concentrate to 45±2 bix at room temperature, which greatly improves production efficiency and reduces production costs. The product water discharged during the concentration process can be used as process water, while solving the problem of the impact of evaporation concentration on collagen peptides.

[0016] Please see Figures 1-2One type of membrane system for high-concentration collagen includes: a feed pump 1, a filter 2, a heat exchanger 3, a high-pressure pump 4, a membrane module 5, and a control cabinet 7. The pressure of the feed pump 1 is controlled at 2-6 bar. The feed pump 1 is located at the system inlet and feeds the filter 2 and provides the pressure required for the filter 2 to operate. It is responsible for supplying the liquid to be treated from the outside into the system. It provides the necessary pressure to ensure that the liquid can pass smoothly through the subsequent processing units. Filter 2 is a security filter with a rejection accuracy of 1-50μm. Before the liquid enters the main processing components, filter 2 is used to remove larger particles or impurities, protecting downstream sensitive equipment from damage. Therefore, filter 2 rejects insoluble substances in the material. Heat exchanger 3 is a shell-and-tube heat exchanger that cools the material to meet the temperature requirements of membrane module 5. High-pressure pump 4 provides driving pressure to membrane module 5. The head of high-pressure pump 4 is 600-800m, which transports the material to membrane module 5. Membrane module 5 separates dissolved substances or small particles from the material using membrane technology before outputting the product. Control cabinet 7 is controlled by PLC or DCS, enabling unmanned operation. Control cabinet 7 controls the automated operation of other components of the system and stores relevant operating data to achieve traceability of production data.

[0017] In order to provide cross-flow to the surface of the membrane module so that pollutants are less likely to deposit on the membrane module, the inlet and outlet of the membrane module 5 are connected to a circulation pump 6. The membrane module 5 can be a spiral wound membrane element, a sanitary membrane element, a high-temperature resistant membrane, or a highly sterile membrane. Among them, the spiral wound membrane element is a nanofiltration or reverse osmosis membrane.

[0018] The following example, using 36 tons of pre-concentrated liquid per day, illustrates the concentration data of this system: The collagen concentration after preliminary concentration by the nanofiltration system is 25-30 bix, and the total annual processing volume of pre-concentrated liquid is approximately 11,000 tons. Assuming 300 production days per year, a daily processing time of 12 hours, and a processing capacity of 3 tons per hour. The high-concentration membrane equipment can concentrate the liquid to a concentration of 45±2 bix, removing a significant amount of water. Furthermore, the liquid concentrated by the membrane is more likely to pass through the subsequent paperboard filtration process compared to the liquid concentrated by scraper evaporation, saving on paperboard waste and filtration time.

[0019] According to calculations, using a high-concentration membrane equipment to concentrate the collagen solution after initial concentration via nanofiltration, the payback period for the high-concentration membrane equipment is within 100 days (the entire investment cost can be recovered within 100 days by utilizing the energy savings). Afterwards, in terms of energy consumption, the production cost per ton of collagen peptides can be reduced by 600 yuan.

[0020] In summary, membrane concentration technology is a membrane process that uses pressure as the driving force to separate and concentrate substances through a membrane. The entire process is heat-free, involves no phase change, and can be completed at room temperature. Membrane technology is used in the concentration of collagen peptides, allowing for concentration at room temperature. During concentration, water in the collagen solution permeates through the membrane under pressure, while collagen is retained, thus achieving concentration. Taking nanofiltration concentrate equipment as an example, the target concentration is 450-500 g / L for a collagen content of 250 g / L, achieving a suitable concentration for spray drying. This is the first time in China that a membrane system has been used to concentrate collagen solution to such a high concentration. The equipment operating cost is approximately 10-15 RMB / ton, achieving energy savings of over 90% compared to the cost of over 200 RMB / ton for scraper concentrate. The equipment uses a continuous concentration method, with the feed solution going from the system inlet to the finished product in just ten to twenty minutes.

[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
