Description

Technical Field

[0001] This utility model relates to the field of biological product production equipment technology, and in particular to a vacuum concentration device for the production of brown algae oligosaccharides. Background Technology

[0002] Vacuum concentration equipment for the production of fucoidan is a specialized device that uses heat to vaporize and remove the solvent, mainly water, from a fucoidan solution under negative pressure, thereby increasing the concentration of the fucoidan solution or recovering the solvent.

[0003] The alginate oligosaccharide solution is pretreated to a suitable concentration, filtered to remove large particulate impurities, and the feed pump is started to slowly inject the pretreated alginate oligosaccharide solution into the concentration tank. At the same time, the heating system is turned on, and the solution temperature is gradually raised to the set value through jacket or coil heating. After the solution temperature stabilizes, the vacuum system is turned on and the pressure is gradually evacuated to the target pressure. Under negative pressure, the alginate oligosaccharide solution is indirectly heated by steam. As the pressure decreases, the boiling point of the solution also decreases. At the lower temperature, the water in the solution continuously vaporizes, changing from liquid to gas. The generated secondary steam is continuously removed, thereby continuously increasing the concentration of the solution until the desired concentration is reached. For example, after the solution enters the concentration tank, it flows inside the heating tube, while the steam flows outside the heating tube. Through heat transfer, the material inside the tube boils. The evaporated steam is drawn out from the top of the separation chamber, and after the entrained droplets are recovered by the demister, it enters the condenser for condensation.

[0004] However, most traditional equipment uses single-effect evaporation, which has low evaporation efficiency and high energy consumption, resulting in long concentration time for fucoidan extract and increased production costs. At the same time, the unreasonable design of the evaporation structure of the equipment leads to uneven heating of the material during the evaporation process, which can easily damage the components of fucoidan and affect product quality. Utility Model Content

[0005] This invention solves the problems of low evaporation efficiency and uneven heating in existing devices, avoids the destruction of brown algae oligosaccharide components, and improves product quality.

[0006] In view of the above-mentioned problem of uneven heating, this utility model is proposed.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vacuum concentration device for the production of brown algae oligosaccharides, comprising a body, an inner wall of the body having a cavity, a material pipe fixedly connected to the inner wall of the cavity, a temperature sensor fixedly installed on the inner wall of the material pipe, a heating pipe nested with the outer wall of the material pipe fixedly connected to the inner wall of the cavity, a plurality of evenly distributed steam heating jackets fixedly connected to the outer wall of the heating pipe, a pressure sensor fixedly installed at the bottom of the inner wall of the cavity, and a vacuum pump communicating with the inner wall of the cavity fixedly installed on the outer wall of the body.

[0008] As a preferred embodiment of the vacuum concentration equipment for producing brown algae oligosaccharides according to this utility model, the inner wall of the machine body is provided with a steam chamber, and the outer wall of the machine body is provided with an air inlet communicating with the inner wall of the steam chamber. A pressure gauge is fixedly connected to the top of the air inlet.

[0009] As a preferred embodiment of the vacuum concentration equipment for producing brown algae oligosaccharides according to this utility model, the outer wall of the machine body is provided with a one-way valve communicating with the inner wall of the steam chamber, and the outer wall of the steam heating jacket is provided with two evenly distributed connecting pipes communicating with the inner wall of the steam chamber.

[0010] As a preferred embodiment of the vacuum concentration equipment for producing brown algae oligosaccharides according to this utility model, the bottom of the machine body is fixedly connected to a base plate, and the bottom of the base plate is fixedly connected to a plurality of evenly distributed support feet that are in contact with the ground. The bottom of the cavity is provided with a discharge port that communicates with the outer wall of the material pipe.

[0011] As a preferred embodiment of the vacuum concentration equipment for the production of brown algae oligosaccharides according to this utility model, the bottom end of the base plate is provided with a through hole to facilitate the sliding of the discharge port, the inner wall of the discharge port is equipped with an electric valve, and the top of the cavity is provided with a feeding port that communicates with the outer wall of the material pipe.

[0012] As a preferred embodiment of the vacuum concentration equipment for the production of brown algae oligosaccharides according to this utility model, a material distributor is fixedly connected to the inner wall of the feeding port, a sealing gasket that is slidably connected to the top of the material distributor is fixedly connected to the inner wall of the feeding port, and multiple evenly distributed diversion pipes that communicate with the inner wall of the material pipe are opened on the inner wall of the material distributor.

[0013] The beneficial effects of this utility model are: 1. After the raw materials are evenly dispersed by the material distributor, they form a thin film on the inner wall of the material tube and flow slowly downwards, making full contact with the heating tube that tightly wraps the material tube. The heat emitted by the heating tube can be transferred to the raw material film in all directions without dead angles, ensuring that the raw materials are heated evenly throughout the concentration process and avoiding local overheating or underheating. At the same time, the slow flow characteristics of the raw material film on the inner wall of the material tube prolong its residence time in the equipment, allowing the raw materials to absorb heat more fully and carry out efficient evaporation and concentration, improving evaporation efficiency, improving product quality, and ensuring that the produced fucoidan oligosaccharides meet high quality standards.

[0014] 2. The temperature sensor monitors the raw material temperature and sends the data to the PLC controller, which then controls the steam flow regulating device at the air inlet to precisely adjust the steam flow rate. This ensures that the raw material is concentrated at a suitable temperature, preventing it from deteriorating due to excessive heat. When the pressure sensor detects abnormal internal pressure, the PLC controller responds quickly and automatically adjusts the vacuum pump's pumping speed to maintain a stable vacuum environment inside the equipment. This reduces production failures and product quality fluctuations, improves production quality and efficiency, and lowers the cost of manual intervention. Attached Figure Description

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1:

[0022] Reference Figure 1-5This is the first embodiment of the present invention, which provides a vacuum concentration device for the production of brown algae oligosaccharides. The device includes a body 1, with a cavity formed in the inner wall of the body 1. A material pipe 9 is fixedly connected to the inner wall of the cavity, and the material pipe 9 is used to drive the raw material to descend in a spiral. A temperature sensor 20 is fixedly installed on the inner wall of the material pipe 9. The temperature sensor 20 uses the principle that the resistance of a thermistor changes with temperature to monitor changes in the temperature of the raw material. A heating tube 10, nested within the outer wall of the material pipe 9, is fixedly connected to the inner wall of the cavity. The heating tube 10 is used to uniformly heat the material pipe 9. Multiple uniformly distributed steam heating jackets 12 are fixedly connected to the outer wall of the heating tube 10. A pressure sensor 13 is fixedly installed at the bottom of the inner wall of the cavity. The pressure sensor 13 senses changes in pressure within the vacuum system pipeline, converts them into electrical signals, and transmits them to an intelligent controller to monitor the vacuum level of the device. A vacuum pump 5, communicating with the inner wall of the cavity, is fixedly installed on the outer wall of the body 1. The vacuum pump 5 is used to evacuate the cavity.

[0023] The inner wall of the body 1 is provided with a steam chamber 19, and a spiral plate is fixedly connected to the inner wall of the steam chamber 19 to facilitate the spiral rise of steam. The outer wall of the body 1 is provided with an air inlet 4 that communicates with the inner wall of the steam chamber 19. A pressure gauge 11 is fixedly connected to the top of the air inlet 4, and the pressure gauge 11 allows the staff to observe the pressure of the steam chamber 19 in real time.

[0024] The outer wall of the body 1 is provided with a one-way valve 8 that communicates with the inner wall of the steam chamber 19, and the outer wall of the steam heating jacket 12 is provided with two evenly distributed connecting pipes 16 that communicate with the inner wall of the steam chamber 19.

[0025] During use, the raw material is fed into the equipment through the feeding port 6. After entering, the raw material passes through the material distributor 14 and is then dispersed into multiple diversion pipes 17. The raw material is then evenly distributed on the inner wall of the material pipe 9 through the diversion pipes 17, forming a thin film of raw material, which then flows downward along the inner wall of the material pipe 9.

[0026] Meanwhile, steam enters the steam chamber 19 through the air inlet 4. Since the inner wall of the steam chamber 19 is equipped with a spiral plate, the steam will spiral upward in the chamber. During the upward process, the steam will pass through the steam heating jacket 12 connected to the steam chamber 19. The steam heating jacket 12 tightly wraps the heating tube 10, and the heat of the steam can be efficiently transferred to the heating tube 10. The heated heating tube 10 heats the raw material film flowing downward in the material tube 9, realizing efficient heat exchange. During the process of the raw material film slowly flowing downward in the material tube 9, it can be fully and evenly heated. After the heat exchange is completed, the steam condenses into water and flows out through the one-way valve 8 for collection, which is convenient for reuse. Example 2:

[0027] Reference Figure 1 , Figure 2 and Figure 5 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a base plate 2 is fixedly connected to the bottom end of the machine body 1, and a plurality of evenly distributed support feet 3 that are in contact with the ground are fixedly connected to the bottom end of the base plate 2. A discharge port 7 that communicates with the outer wall of the material pipe 9 is opened at the bottom end of the cavity.

[0028] The bottom of the base plate 2 has a through hole for easy sliding of the discharge port 7. An electric valve 15 is installed on the inner wall of the discharge port 7. The top of the cavity has a feeding port 6 that communicates with the outer wall of the material pipe 9.

[0029] A material distributor 14 is fixedly connected to the inner wall of the feeding port 6. The material distributor 14 is used to evenly distribute the raw materials on the inner wall of the material pipe 9. A sealing gasket 18 is fixedly connected to the top of the material distributor 14 and is slidably connected to the inner wall of the feeding port 6. Multiple evenly distributed diversion pipes 17 are opened on the inner wall of the material distributor 14 and are connected to the inner wall of the material pipe 9.

[0030] During use, when the pressure sensor 13 detects an abnormal pressure inside the equipment, it will transmit a signal to the PLC controller. After receiving the signal, the PLC controller will automatically adjust the pumping speed of the vacuum pump 5 according to the preset program. If the pressure is too high, the pumping speed of the vacuum pump 5 will be increased to reduce the pressure inside the equipment and maintain a stable vacuum environment. If the pressure is too low, the pumping speed will be reduced to avoid excessive pumping that could affect the concentration effect. When the temperature sensor 20 detects that the raw material temperature deviates from the set range, it will also send a signal to the PLC controller. The PLC controller will control the steam flow regulating device at the air inlet 4 to increase the flow of steam through the air inlet 4, so that more steam enters the steam chamber 19, thereby increasing the temperature of the heating tube 10 and ensuring that the raw material is concentrated at a suitable temperature.

[0031] The remaining structure is the same as that in Example 1.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
