[0002] In the processing of ginseng extract, spray drying technology is often used to convert the liquid extract into powder for convenient storage and use. However, in existing technologies, the contact path between hot air and spray is short and the contact time is insufficient, resulting in low heat exchange efficiency and affecting the drying effect. Utility Model Content

[0003] This utility model addresses the problems of existing technologies by providing a spray drying device for ginseng extract, the specific technical solution of which is as follows:

[0004] The spray drying device for ginseng extract includes:

[0005] ontology;

[0006] The nozzle is coaxially mounted on the top of the body and is used to release a spray.

[0007] At least one set of air ducts, which are located at the top of the body, for releasing hot air;

[0008] And a spiral component, which is disposed within the body and forms a spiral channel that guides the spray and hot air into contact.

[0009] As a further technical solution of this utility model, the body includes:

[0010] The heat exchange chamber is used to facilitate heat exchange with spray and hot air.

[0011] The discharge pipe is located at the bottom of the heat exchange chamber, and a discharge port is provided along the lower edge of the discharge pipe to guide the powdered extract out.

[0012] The spiral component is installed inside the heat exchange chamber of the main body.

[0013] As a further technical solution of this utility model, the air duct is inserted into the body at an angle along the chamfer.

[0014] As a further technical solution of this utility model, when multiple sets of air ducts are provided, the multiple sets of air ducts are evenly distributed around the spray pipe.

[0015] As a further technical solution of this utility model, there is a gap between the edge of the spiral component and the inner wall of the heat exchange chamber to form an annular channel.

[0016] As a further technical solution of this utility model, it also includes a rotatable shaft, which is coaxially connected to the bottom of the spiral component, and the rotating shaft can drive the spiral component to rotate when it rotates;

[0017] The spiral component rotates in the reverse spiral direction.

[0018] As a further technical solution of this utility model, it also includes a scraper, which is connected to the rotating shaft and laid along the trajectory of the inner wall of the heat exchange chamber. When the rotating shaft rotates, it can drive the scraper to scrape off the powdery extract adhering to the surface of the heat exchange chamber.

[0028] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0029] Figure 1 A schematic diagram of the overall structure of the spray drying device for ginseng extract is shown; Figure 2 A schematic diagram of the internal structure of a spray drying device for ginseng extract is shown.

[0030] Figure 1 and Figure 2 The spray drying device for the bamboo joint ginseng extract includes:

[0031] Ontology 100;

[0032] The nozzle 200 is coaxially mounted on the top of the body 100 and is used to release spray.

[0033] And at least one set of air ducts 300, which are inclined along a tangent at the top of the body 100 for releasing hot air.

[0034] The nozzle 200 and air duct 300 at the top of the main body 100 release a spray and hot air containing the extract, respectively. As they fall inside the main body 100, they exchange heat and precipitate powdered extract.

[0035] The nozzle 200, through its coaxial design, transforms the bamboo ginseng extract solution into micron-sized droplets using high-pressure atomization technology. These droplets are then released downwards from the top center of the main body 100, ensuring uniform dispersion of the spray within the main body 100 and preventing localized aggregation. Simultaneously, the air duct 300, angled at a bevel, releases high-temperature hot air into the main body 100. This beveled angle creates a rotating airflow, extending the contact path and time between the hot air and the spray. As the atomized droplets fall, they come into full contact with the rotating hot air, causing rapid evaporation of moisture from the droplet surface. This heat exchange facilitates the transformation of the extract from a liquid state to a powdered form.

[0036] Body 100 includes:

[0037] The heat exchange chamber 110 is used to facilitate heat exchange with spray and hot air.

[0038] The discharge pipe 120 is located at the bottom of the heat exchange chamber 110, and the discharge pipe 120 has a discharge port 121 at its lower edge to guide the powdered extract out.

[0039] The heat exchange chamber 110 provides a closed space for heat exchange between the spray and hot air. Its internal volume is designed according to the drying capacity to ensure that the airflow and spray have sufficient residence time in the chamber to complete the drying process. The dried powdered extract falls from the bottom of the heat exchange chamber 110 into the discharge pipe 120 under the influence of gravity and the rotating airflow. The discharge pipe 120 has a tubular structure and guides the powder to gather at the discharge port 121 by gravity, and finally discharges and collects it from the discharge port 121. The heat exchange chamber 110 provides a closed environment to reduce heat loss and energy consumption, while preventing external impurities from entering and ensuring the purity of the extract. The design of the discharge pipe 120 and the discharge port 121 enables directional collection of powder and reduces powder residue in the device.

[0040] The spray drying device for ginseng extract also includes:

[0041] The spiral component 400 is disposed within the heat exchange chamber 110 and forms a spiral channel that guides the spray and hot air into contact. There is a gap between the edge of the spiral component 400 and the inner wall of the heat exchange chamber 110 to form an annular channel. The spiral channel it forms guides the spray and hot air to move along the spiral path, prolonging the contact time. The gap between the edge and the inner wall of the heat exchange chamber 110 forms an annular channel, allowing some airflow and powder to flow and avoiding channel blockage. At the same time, the spiral component 400 rotates in the opposite spiral direction with the rotating shaft 500, further enhancing airflow turbulence, significantly improving the mixing efficiency of the spray and hot air, and reducing problems such as local overheating or insufficient drying.

[0042] The rotating shaft 500 is rotatably coaxially connected below the screw component 400. When the rotating shaft 500 rotates, it can drive the screw component 400 to rotate in the opposite spiral direction. Driven by the output motor 800, it rotates and transmits power to the screw component 400, scraper 600 and auger 700 to achieve synchronous movement of multiple components.

[0043] The scraper 600 is connected to the rotating shaft 500 and is laid along the inner wall of the heat exchange chamber 110. When the rotating shaft 500 rotates, it can drive the scraper 600 to scrape off the powdery extract adhering to the surface of the heat exchange chamber 110. As the rotating shaft 500 rotates, it scrapes closely against the inner wall of the heat exchange chamber 110 to remove the powder that adheres to the chamber wall due to static electricity or humidity, preventing accumulation and clumping, avoiding deterioration of the extract due to long-term retention, and maintaining the smoothness of the inner wall of the heat exchange chamber 110 to ensure airflow stability.

[0044] The auger 700 is coaxially connected to the outside of the rotating shaft 500 and placed inside the discharge pipe 120. When the rotating shaft 500 rotates, it can drive the auger 700 to rotate and transport the powdered extract. The auger 700 rotates with the rotating shaft 500 inside the discharge pipe 120, and pushes the powder to the discharge port 121 through the spiral blades, actively transporting the powder and avoiding the powder from stagnating in the discharge pipe 120. This solves the problem of possible agglomeration and blockage in the discharge pipe 120 and ensures smooth discharge.

[0045] The output motor 800 is located on the outer side of the bottom of the discharge pipe 120, and the output end of the output motor 800 is connected to the rotating shaft 500 for transmission. As a power source, the rotation speed of the rotating shaft 500 and related components is adjusted by controlling the rotation speed to adapt to the drying requirements of extracts with different concentrations and viscosities.

[0046] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
