Description

Technical Field

[0001] This application relates to the field of separation technology, and in particular to an aromatic substance separation column system. Background Technology

[0002] In the industrial production of plant extracts, fruit and vegetable juices and concentrates, and natural compound beverages, there is a common phenomenon of significant loss of natural aroma components. To cover up the loss of aroma, companies often use synthetic esters, aldehydes or thiols for secondary flavoring. Although this technique can restore some flavor, it has the following limitations: (1) The chiral ratio, isotopic abundance and trace associated components of the chemically synthesized flavoring are not consistent with the homologues in the natural matrix, resulting in a deviation at the sensory level; (2) Some synthetic flavorings are easily oxidized or polymerized by light, oxygen and metal ions during storage, forming potentially toxic compounds that are harmful to the human body.

[0003] With increasing public awareness of health and the globalization of "zero additives" and "clean label" consumption trends, the market demand for traceable, chemically unmodified, and sensorily intact natural aroma recovery technologies is becoming increasingly urgent. Research shows that plant extract and large juice companies have extremely high requirements for the reproduction of characteristic aromas such as floral and fruity notes during the final blending stage. If it is possible to efficiently capture and standardize the enrichment of elusive useful flavor substances at the processing stage, and then add them back to the original product or extend them as high-value-added flavor bases to the food, daily chemical, tobacco, and biochemical culture media fields, it can not only replace some chemically synthesized additives but also open up a second growth curve for companies, distinct from traditional raw material sales.

[0004] Based on the aforementioned industry needs, this application proposes a multi-phase aromatic substance separation system, which aims to selectively separate, directionally enrich, and recycle natural aromas in complex multiphase systems under mild conditions, thereby overcoming the sensory and safety defects of synthetic fragrances and meeting the new consumer demand for natural and safe products in the era of health and wellness. Utility Model Content

[0005] To address the problems of volatile flavor compounds and difficulty in effective recovery during the processing of plant or fruit raw materials, which lead to insufficient aroma and unstable quality in the final extract, this application provides a dual-disc aromatic substance separation column system. This system achieves efficient enrichment and fine separation of natural flavor compounds by optimizing the disc separation structure, enhancing the directional transport path of volatile components, and combining it with vacuum-assisted condensation technology.

[0006] This application provides a double-disc aromatic substance separation column system, which adopts the following technical solution:

[0007] A disc-type aromatic substance separation column system includes a disc rotary separator. The disc rotary separator has a rotating shaft inside, one end of which extends out of the separator and is connected to a variable frequency motor via a transmission component. The disc rotary separator has a feed inlet, which is connected to a liquid inlet pump via a pipeline and a flow meter installed on the pipeline. The disc rotary separator also has a discharge outlet, which is connected in series with a gas-liquid separator via a pipeline and connected to one end of a condenser. One end of the condenser is connected to a collection tank via a vacuum suction pipe. The bottom of the disc rotary separator has a heavy phase discharge outlet and a sludge discharge outlet. The side of the disc rotary separator has a steam inlet. The electrical components in the system are electrically connected to an electrical control box.

[0008] Using the above technical solution, during operation, the material enters the disc rotary separator through the feed inlet at the top of the equipment. After passing through the guide disc, it reaches the next high-speed centrifugal disc, where a liquid film forms on the surface. Heating steam is supplied through the external steam inlet to directionally heat the guide disc or the area below it, causing the volatile flavor components in the material to be preferentially vaporized. The vaporized components are then rapidly discharged along the discharge channel under the vacuum at the top of the equipment, entering the subsequent gas-liquid separator and condenser. In the condenser, the volatile components are condensed into liquid through heat exchange with cooling water and finally collected in a collection tank. Throughout the process, non-volatile components are retained in the equipment and discharged through the bottom heavy phase outlet or drain outlet.

[0009] Preferably, the aromatic substance separation system includes modules such as a flow meter, a disc rotary separator, a variable frequency drive motor, a gas-liquid separator, a condenser, and a collection tank, which are connected by pipelines to form a closed-loop continuous process.

[0011] Preferably, the aromatic substance separation system includes a disc-type rotary separator, which has multiple liquid guiding discs and centrifugal rotating discs inside. The liquid guiding discs and centrifugal rotating discs are distributed alternately to form multi-stage liquid films and centrifugal separation interfaces.

[0013] Preferably, the side wall of the separator is provided with a steam heating inlet, which is connected to a steam heating system through a pipe for directional heating of the bottom of the liquid guide plate inside the separator.

[0014] By adopting the above technical solutions, setting up a steam heating inlet can achieve localized and fixed-point heating, causing the material on the surface of the liquid guide plate to form a liquid film and assisting in evaporation, thereby improving separation efficiency and avoiding excessive energy consumption caused by heating the whole machine.

[0015] Preferably, the disc-type rotary separator is the core unit of the system. It has a feed inlet and a product outlet at the top, a heavy phase outlet and a sludge outlet at the bottom, and multiple conical discs inside to form a high centrifugal force field to enhance the phase separation process.

[0016] More preferably, a variable frequency drive motor is connected to the bottom of the separator, and a rotating shaft is connected to the output end of the motor. This rotating shaft passes through the central axis of the separator and drives the discs to rotate for efficient separation. The rotating shaft and the separator are sealed and linked through a bearing structure.

[0017] By adopting the above technical solutions and setting up a variable frequency motor and rotating shaft structure, the rotation speed can be adjusted according to the characteristics of different materials, the centrifugal force and evaporation conditions can be optimized, and the separation efficiency and adaptability can be improved.

[0018] Preferably, the light phase or gaseous product from the product outlet enters a gas-liquid separator to separate entrained gases. The upper part of the gas-liquid separator is connected to a condenser, and the lower part is connected to the product output pipeline.

[0019] The liquid phase outlet of the gas-liquid separator is connected to a drain pipe for recovering liquid phase components or performing secondary treatment.

[0020] Preferably, the condenser is a vertical shell-and-tube structure, with a cold water inlet at one end and a cold water outlet at the other end, connected to an external cooling water circulation system. A vacuum port is connected to the top of the condenser to create negative pressure and improve condensation efficiency; a collection tank is connected to the bottom of the condenser.

[0021] By adopting the above technical solutions, the condenser can be installed to quickly liquefy high-temperature volatile components, ensuring that flavor substances are effectively condensed and collected in the collection tank, thus reducing volatilization loss.

[0022] Preferably, the collection tank is a stainless steel sealed tank with an observation window and a discharge port at the bottom of the tank, used to collect the condensed aromatic liquid, so as to facilitate the periodic discharge of condensed products and prevent secondary pollution.

[0023] Preferably, the system is equipped with an electrical control box, which is electrically connected to the variable frequency motor, flow meter, steam heating system, cooling water system, etc., for centralized control of the entire separation system.

[0024] By adopting the above technical solutions, the electrical box controller enables the coordinated operation and parameter adjustment of multiple devices, including real-time temperature, flow rate, and speed control, thereby improving the system's automation level and operational safety.

[0036] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solutions of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0037] The following is in conjunction with the appendix Figure 1 , 2 This application will be described in further detail.

[0038] The following detailed description of the working process of the aromatic substance separation system provided by the present invention is based on an implementation example. However, this embodiment is only used to explain the present invention and does not limit the scope of protection of the present invention.

[0039] This implementation uses a double-disc aromatic substance separation column system to separate and extract natural rose aromatic substances. The implementation process is as follows:

[0040] Raw material pretreatment: 3 kg of dried rose petals were selected as raw material and added to 30 liters of 30°C warm water at a mass-to-volume ratio of 1:10. The mixture was soaked for 2 hours under normal pressure to promote the full dissolution of aromatic components. After soaking, solid-liquid separation was performed using a centrifuge to obtain approximately 20 kg of liquid filtrate, which was used as raw material for subsequent separation.

[0041] Equipment Start-up and System Preparation: Start the electrical control box 20 to power on the system and check the operating status of each module, including the variable frequency drive motor 13, feed pump 11, steam system 9, condenser system 15, and vacuum suction system 18. Connect the pretreated filtrate to the feed pump 11 through a pipeline and adjust the feed line to the main unit inlet 1. Set the feed flow rate to 1.5 L / min in the electrical control box 20.

[0042] The feed pump 11 is turned on, and the liquid filtrate obtained in the raw material pretreatment enters the top feed port 1 of the disc rotary separator at a continuous and stable rate of 1.5 L / min. After entering the main unit 3, the filtrate flows through the liquid guide disc 5 and into the rotating disc 4.

[0043] Turn on the variable frequency drive motor 13 and set the rotation speed of the rotating shaft 7 of the disc-type rotary separator 3 to 720 rpm. The variable frequency drive motor 13 drives the rotating shaft 7 to rotate, which runs through the central axis of the separator. This drives the liquid guiding disc and centrifugal disc inside the separator to rotate at high speed, forming a continuous liquid film and centrifugal force field, which enhances the volatilization of light aromatic components in the material. Connect the steam inlet 9 on the side wall of the separator to provide steam to the bottom area of ​​the liquid guiding disc 5 inside the separator for heating, thereby increasing the internal temperature to assist volatilization.

[0044] The filtrate is centrifuged and heated, and the volatile components formed after heating flow to the top outlet along with the light phase generated by the rotation. The incompletely separated concentrated liquid and impurities are discharged from the system through the bottom heavy phase outlet 8 and the drain outlet 6.

[0045] The light phase gas produced from the target material outlet 2 at the top of the main unit enters the gas-liquid separator 14 through a pipeline, separating the small amount of residual liquid carried out with the target aromatic gas.

[0046] The separated target aromatic gas enters the condenser 15 through a pipeline, while the condenser cooling water inlet 16 and outlet 17 are simultaneously connected to ensure a stable closed-loop circulation in the cooling system. After entering the condenser, the target aromatic gas is condensed into liquid aromatic products by the cooling water. Subsequently, the vacuum suction port 18 at the bottom of the condenser is opened to maintain a negative pressure state inside, which is conducive to the low-temperature volatilization and condensation process.

[0047] The condensed aromatic liquid is finally collected in a sealed collection tank 19 at the bottom. The collection tank is equipped with an observation window and a discharge port at the bottom to facilitate observation, sampling and subsequent use, and to periodically discharge the condensed products and prevent secondary pollution.

[0048] The above implementation process demonstrates and describes the basic principles, main features, and advantages of the present invention. The specific embodiments described above are not intended to limit the scope of protection of this application; therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
