Description

Technical Field

[0001] This utility model relates to a rake-type drying device for glycyrrhizin, belonging to the technical field of rake-type drying and ethanol recovery of glycyrrhizin. Background Technology

[0002] Currently, in the production of glycyrrhizin (requiring a drying loss of less than 10%), most of the equipment used is the rake dryer. A rake dryer typically consists of a dryer body, a heating system, a vacuum system, a filtration system, and a condensation system. The ultimate requirement for rake dryers in actual use is to ensure acceptable drying loss, maximize the recovery of ethanol solvent from the material, and ensure convenient and smooth material collection. Existing rake dryer equipment often presents the following problems in actual production operation: (1) There is only one condenser to condense and recover ethanol solvent. Chilled water is circulated in the condenser. The temperature is limited by the overall temperature of the refrigeration system. The recovered solvent is warm and the solvent recovery efficiency is low. (2) The temperature of the circulating water in the vacuum system will gradually increase with the duration of vacuum circulation, which will eventually lead to a decrease in the vacuum level. In order to maintain the vacuum level, it is always necessary to frequently replace the vacuum circulating water with cold water, which is time-consuming and laborious. (3) The material discharge of the dryer is straight up and down and there is only one valve to control the discharge rhythm. It is often difficult to control the discharge rhythm and multiple people need to cooperate in operation. One person controls the valve opening and another person collects the material, which is wasteful of manpower and inconvenient. Utility Model Content

[0003] In order to solve the problems existing in the prior art, this utility model makes several improvements on the basis of the existing rake dryer, and provides a licorice protein rake drying device that can better meet production needs.

[0004] The technical solution of this utility model is as follows: A rake-type drying device for licorice protein includes a drying body, a filter, a condenser, a receiving tank, a vacuum system, and a heating system. The drying body, filter, condenser, receiving tank, and vacuum system are connected in sequence via vacuum tubes. The vacuum system is used to evacuate the drying body, and the heating system is used to provide heat energy to the drying body. The condensation device includes two condensers connected in series; A condenser coil is installed in the vacuum water tank of the vacuum system, and chilled water is circulated in the condenser coil to cool the vacuum circulating water in the vacuum water tank. The discharge port of the dryer body includes a vertical section and an inclined section. One end of the vertical section is connected to the dryer body, and the other end is connected to the inclined section. A first butterfly valve is provided at the connection between the vertical section and the inclined section, and a second butterfly valve is provided at the end of the inclined section away from the vertical section.

[0005] As a preferred embodiment of this invention, the heating system supplies steam to the dryer body through a steam pipe. The steam enters the jacket of the dryer body to heat the dryer body, and a steam condensate outlet is provided at the bottom of the dryer body.

[0006] As a preferred embodiment of this invention, a steam valve is provided on the steam pipe.

[0007] As a preferred embodiment of this invention, the filter is a bag filter.

[0008] As a preferred embodiment of this invention, the angle between the inclined section of the discharge port of the dryer and the horizontal plane is 45 degrees.

[0009] As a preferred embodiment of this invention, the cooling medium used in the condenser is chilled water.

[0010] The advantages of this utility model are: Based on the traditional rake dryer's straight-up-down discharge port, the discharge port is extended and tilted at 45 degrees. Two butterfly valves are installed for discharge control, allowing workers to manage the discharge rhythm and achieve smooth discharge. The structure is reasonable and compact, simple and convenient to operate, and ensures smooth discharge. Two condensers connected in series are installed to condense and collect the solvent, improving solvent recovery efficiency and effectiveness. This maximizes solvent recovery while ensuring the glycyrrhizin material meets the required drying weight loss. A condensing coil is installed in the vacuum water tank of the vacuum system, through which chilled water is circulated to cool the vacuum circulating water in the tank. This ensures smooth operation of the vacuum system, eliminating the need for frequent vacuum circulating water replacements, enabling continuous production, shortening the drying cycle, and effectively improving production efficiency while reducing production costs.

Detailed Implementation

[0012] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0013] like Figure 1As shown, this embodiment is a licorice protein rake-type drying device, including a drying body 1, a filter 2, a condenser 3, a receiving tank 4, a vacuum system 5, and a heating system; the drying body 1, filter 2, condenser 3, receiving tank 4, and vacuum system 5 are connected in sequence through a vacuum tube 6. The vacuum system 5 is used to evacuate the drying body 1, and the heating system is used to provide heat energy to the drying body 1.

[0014] To maximize solvent recovery, the condensation device 3 in this embodiment includes two condensers 31 connected in series. The cooling medium used in the condensers 31 is chilled water. The two condensers 31 connected in series are used to condense and collect the dried solvent, thereby improving the solvent recovery efficiency. The solvent eventually flows into the receiving tank 4. In order to cool the vacuum circulating water, a condensing coil 8 is installed in the vacuum water tank 7 of the vacuum system 5 in this embodiment. Chilled water is introduced into the condensing coil 8 to cool the vacuum circulating water in the vacuum water tank 7, so that the vacuum system 5 can operate well without frequent replacement of the vacuum circulating water.

[0015] To facilitate workers' control over the discharge rhythm, in this embodiment, the discharge port 10 of the dryer body 1 includes a vertical section 11 and an inclined section 12. One end of the vertical section 11 is connected to the dryer body 1, and the other end is connected to the inclined section 12. A first butterfly valve 21 is provided at the connection between the vertical section 11 and the inclined section 12, and a second butterfly valve 22 is provided at the end of the inclined section 12 away from the vertical section 11. By providing two butterfly valves, it is more convenient for workers to control the discharge rhythm. The angle between the inclined section 12 of the discharge port 10 of the dryer body 1 and the horizontal plane is 45 degrees, which further realizes a smooth discharge.

[0016] In this embodiment, the heating system supplies steam to the dryer body 1 through the steam pipe 13. The steam enters the jacket of the dryer body 1 to heat the dryer body 1. A steam condensate outlet 14 is provided at the bottom of the dryer body 1, and a steam valve 15 is provided on the steam pipe 13 to control the steam flow.

[0017] In this embodiment, filter 2 is a bag filter used to prevent the dried protein material from being vacuumed away.

[0018] During use, the glycyrrhizin material to be dried is fed into the feed port 9 of the dryer body 1, and then the feed port 9 is closed. The dryer body 1, heating system, filter 2, two condensers 31, receiving tank 4, vacuum system 5, condensing coil 8 and other equipment are started. The vacuum pump 51 of the vacuum system 5 evacuates the dryer body 1. The heating system supplies steam. The steam is directly introduced into the jacket of the dryer body 1 through the steam pipe 13 and steam valve 15 to heat the dryer body 1, thereby heating and drying the glycyrrhizin material inside the dryer body 1. During the vacuum drying process, the dried ethanol solvent is condensed and collected at two condensers 31 connected in series and flows into the receiving tank 4. The chilled water flowing into the condenser coil 8 continuously cools the vacuum circulating water in the vacuum system 5, preventing the vacuum circulating water temperature from gradually rising and the vacuum from decreasing as the vacuum system 5 runs longer, thus maintaining the long-term stable operation of the vacuum system 5. Finally, after the drying is completed, the glycyrrhizin that meets the requirements for drying weight loss is discharged and collected from the inclined section 12 of the discharge port 10 of the dryer body 1 at an inclination of 45 degrees.

[0019] This invention extends and tilts the discharge port by 45 degrees on the basis of the traditional straight-up-down discharge port of the rake dryer, and simultaneously sets up two butterfly valves for discharge control, which helps workers control the discharge rhythm and achieve smooth discharge. The structure is reasonable and compact, the operation is simple and convenient, and the discharge is smooth. Two condensers connected in series are set up to condense and collect the solvent, improving the solvent recovery efficiency and effect. While ensuring that the glycyrrhizin material meets the drying loss requirement, the solvent is recovered to the maximum extent. A condensing coil is set in the vacuum water tank of the vacuum system. Chilled water is circulated in the condensing coil to cool the vacuum circulating water in the vacuum water tank, so that the vacuum system can operate smoothly without frequent replacement of vacuum circulating water, realizing continuous production, shortening the drying cycle, and thus effectively improving production efficiency and reducing production costs.
