Description

Technical Field

[0001] This utility model relates to the technical field of licorice extract preparation equipment, and in particular to a high-efficiency licorice extract preparation equipment. Background Technology

[0002] Licorice extract is a paste or powder preparation made from licorice through extraction and concentration processes. In the conventional preparation process of licorice extract, the licorice is first pretreated to remove impurities; then extraction is performed to dissolve water-soluble components; next, the extract is concentrated; finally, the concentrated solution is dried to obtain a block-shaped licorice extract, or it can be further pulverized into powder.

[0003] In the drying process, spray drying and vacuum drying are commonly used. For drying licorice extract, spray drying is often employed, where the concentrated liquid is atomized and then contacted with hot air (inlet air temperature 160-180℃) to instantly dry into powder, achieving a yield of over 90%. For example, Chinese utility model patent CN207936723U discloses an improved instant drying device for preparing licorice extract, including a conveying device, a hot air device, a drying tower, a recovery device, and a weighing device. In actual use, a diaphragm pump lifts the material to the material distribution device, where it is evenly sprayed through a nozzle. Simultaneously, the hot air blower is activated, causing the downward-falling material to travel in the opposite direction to the upward-blowing hot air, thus thoroughly drying the material. The dried material is carried by the airflow to the right side of the baffle plate, with some material discharged through the outlet pipe and recycled by the collection box. The material entering the right side of the baffle plate falls into the collection box through a filter plate.

[0004] In this scheme, high-temperature hot air is used to achieve rapid drying. However, excessively high temperatures can cause heat-sensitive components in the concentrate to volatilize or degrade and be lost with the hot air. As a result, the yield of the finished product is not high and the purity and quality are poor.

[0005] Conventional vacuum drying involves drying the concentrate into blocks at 50-60℃, then pulverizing and passing it through an 80-mesh sieve, which is suitable for preserving heat-sensitive components. However, conventional vacuum drying equipment requires a long time for the drying process in licorice extract preparation, resulting in low preparation efficiency. Utility Model Content

[0006] To address the shortcomings in the aforementioned background technology, this utility model proposes a highly efficient preparation device for licorice extract, which solves the problem of low drying efficiency in the preparation of licorice extract using existing vacuum drying equipment.

[0013] Preferably, the spindle and the vessel body are rotatably coupled via a bearing, and a rotary sealing ring is provided between the spindle and the vessel body.

Detailed Implementation

[0021] 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.

[0022] like Figure 1 , 2 As shown in Example 1, a high-efficiency preparation device for licorice extract includes a support frame 1, which provides a supporting foundation for the entire device. A core tube 2 is fixedly mounted on the support frame 1, passing through the axis of the vessel body 3, and the vessel body 3 and the core tube 2 are rotatably connected. The core tube can support the vessel body. The core tube 2 is connected to a vacuum system 4. In this embodiment, the vacuum system can provide an extremely low-pressure environment to the internal space of the vessel body outside the core tube, lowering the boiling point of water, reducing the temperature required for drying, and accelerating the evaporation of water. This avoids the problem of overheating and degradation or evaporation of heat-sensitive substances caused by the hot air drying method used in the prior art, thereby improving the purity of the purified licorice extract. A stirring scraper 5 is fixedly mounted on the core tube 2, and a drive mechanism 6 is provided on the support frame 1 to drive the vessel body 3 to rotate. Under the drive of the drive mechanism, the vessel body can be rotated. During the rotation of the vessel body, the stirring scraper stirs the extract and can scrape the licorice extract from the inner wall of the vessel body during and after the drying process. The vessel body 3 and the core tube 2 are equipped with inlet and outlet structures. In addition, a microwave transmitter 7 is fixedly installed on the core tube 2. The microwave transmitter 7 is a conventional microwave transmitter that provides a microwave physical field and heats the product through high-frequency electromagnetic waves. This, combined with the extreme low-pressure environment, improves the drying efficiency.

[0023] As a further specific embodiment, the spindle 2 and the vessel body 3 are rotatably coupled through bearing 21, and a rotary sealing ring 22 is provided between the spindle 2 and the vessel body 3. In this embodiment, a total of two sets of bearings and sealing rings are provided, which are coupled to both sides of the vessel body from both ends of the spindle to achieve rotational coupling and sealing during rotation, so as to maintain the continuous effectiveness of the extreme low pressure environment.

[0024] In this embodiment, the concentrated liquid to be dried is first introduced into the reactor body through the inlet / outlet structure, and then the inlet / outlet structure channel is closed. The vacuum system is activated to maintain an extremely low-pressure environment inside the reactor body. Simultaneously, the microwave transmitter is activated to emit microwaves into the reactor body for high-frequency heating, improving drying efficiency. The drive mechanism is then activated, causing the reactor body to rotate. This, combined with the stirring scraper, continuously mixes and stirs the concentrated liquid inside the reactor body. After the water is released, the concentrated liquid solidifies to form licorice extract, some of which adheres to the inner wall of the reactor body. As the reactor body rotates, the stirring scraper scrapes off the adhered licorice extract. Finally, the reactor body pressure is restored, and the finished licorice extract is removed using the inlet / outlet system. This equipment combines a vacuum environment with microwave treatment, along with thorough stirring by the stirring scraper, improving drying efficiency, reducing the loss of heat-sensitive substances, and increasing the yield of the finished product.

[0025] Example 2 provides a high-efficiency preparation device for licorice extract. Based on Example 1, the vacuum system 4 includes a vacuum tube 41. One end of the vacuum tube 41 passes through an opening in the central tube 2 and communicates with the interior of the vessel body 3. The other end of the vacuum tube 41 is connected to a vacuum pump 42 fixedly mounted on a support 1. The outer wall of the vacuum tube is sealed to the opening in the central tube to prevent air leakage. In use, the vacuum pump is turned on, drawing air from inside the vessel body through the vacuum tube and discharging it to the outside, thereby maintaining an extremely low-pressure environment inside the vessel body.

[0026] In addition, an air inlet valve 43 is provided on the vacuum tube. After drying is completed, the air inlet valve is opened, and gas enters the interior of the vessel from the outside through the vacuum tube so that the finished material can be taken out through the feeding and discharging structure later.

[0027] Example 3 discloses a high-efficiency preparation device for licorice extract. Based on Example 2, the driving mechanism 6 includes a drive motor 61 fixedly mounted on a support 1, a pulley I 62 coaxially fixed on the vessel body 3, and a pulley II 63 at the output end of the drive motor 61. The pulley II 63 is connected to the pulley I 62 via a transmission belt 64. In this example, the pulley I is an annular pulley, fixed to the side wall of the vessel body by bolts. In actual use, the drive motor operates, driving the pulley II to rotate, which in turn drives the pulley I to rotate under the action of the transmission belt, ultimately achieving the purpose of rotating the vessel body connected to the pulley.

[0028] In addition, such as Figure 3 As shown, the stirring scraper 5 includes a support rod 51 fixedly mounted on the shaft tube 2. The support rod 51 is connected to an arc-shaped scraper 52, which fits into the inner wall of the vessel body 3. In this embodiment, the support rod provides a connection base for fixing the arc-shaped scraper, and the blade of the arc-shaped scraper is mounted on the inner wall of the vessel body, so that the material adhering to it can be scraped off when the vessel body rotates.

[0029] Example 4: A high-efficiency preparation device for licorice extract. Based on Example 3, the feeding and discharging structure includes a discharge port 31 on the vessel body 3, with a sealing gate 32 on the discharge port 31. A feed pipe 36 is fixedly inserted inside the core tube 2, with its opening passing through an opening on the core tube 2 and communicating with the interior of the vessel body 3. A valve is provided on the feed pipe 36. The outer wall of the feed pipe is sealed to the opening of the core tube to prevent air leakage. In actual use, the feed pipe is connected to a conventional hopper or liquid tank. The hopper or liquid tank contains the concentrated extract of licorice, which is then concentrated. After opening the valve, the concentrated extract enters the valve body through the feed pipe. After feeding is completed, the valve is closed to maintain airtightness.

[0030] Specifically in this embodiment, such as Figure 4 As shown, the sealing door 32 is an arc-shaped door, hinged to the discharge port 31. The structure of the arc-shaped door is the same as the structure of the vessel body at the discharge port, thus maintaining the integrity of the vessel body structure when the door is closed at the discharge port. A sealing ring is provided on the discharge port 31 to maintain a seal when the door is closed.

[0031] As a further specific embodiment, a T-shaped lock head 33 is hinged to the vessel body 3, and a latch 34 for inserting the T-shaped lock head 33 is provided on the sealing door 32. A locking nut 35 is provided on the T-shaped lock head 33 for locking the position of the latch 34. When the sealing door is closed, the end of the T-shaped lock head is inserted into the latch, and the latch is locked onto the latch using the locking nut. At this time, the sealing door is tightly closed over the discharge port. When it is necessary to discharge material, the locking nut is removed, the T-shaped lock head separates from the latch, the sealing door is rotated to open the discharge port, and the finished licorice extract material is taken out.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
