Description

Technical Field

[0001] This utility model relates to a device for removing ethanol residues from glycyrrhizic acid ammonium salts, belonging to the technical field of ethanol residue removal from glycyrrhizic acid ammonium salts. Background Technology

[0002] Currently, in the production of ammonium glycyrrhizate (where ethanol residue needs to be controlled below 0.5%), vacuum ovens are mostly used. To control ethanol residue below 0.5% during the drying process, drying is often stopped after the material is partially dried, and then the oven is opened to manually mix water into each tray before reheating and drying. This method has the following problems:

[0003] (1) Manual water mixing is time-consuming and labor-intensive. Before mixing water, it is necessary to wait for the temperature inside the oven to cool down. After mixing water, it is necessary to wait for the temperature inside the oven to rise to the drying temperature again, resulting in a long production cycle.

[0004] (2) The equipment operation is complicated during the production process. When manually mixing water, the vacuum system, hot water system and cooling system need to be shut down in the middle. After the water mixing is finished, each system needs to be restarted. The operation is complicated, time-consuming and labor-intensive. Utility Model Content

[0021] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0022] like Figure 1 As shown, this embodiment is a device for removing residual glycyrrhizic acid ammonium salt ethanol, including an oven 1, a condenser 2, a receiving tank 3, a vacuum system 4, a heating system, and an atomizing spray system; wherein the oven 1, condenser 2, receiving tank 3, and vacuum system 4 are connected in sequence through a vacuum tube 5, and the vacuum system 4 is used to evacuate the oven 1; the heating system is used to provide heat energy to the oven 1; the atomizing spray system includes a water supply pipe 6 and an atomizing spray pipe 7, one end of the water supply pipe 6 is connected to an external water supply system, and the other end is connected to the atomizing spray pipe 7, and the atomizing spray pipe 7 is provided with an atomizing nozzle 8; an atomizing spray pipe 7 is provided above each drying tray (not shown in the figure) inside the oven 1, and the atomizing nozzle 8 provided on the atomizing spray pipe 7 is used to spray water mist onto the drying tray.

[0023] The heating system in this embodiment includes a hot water tank 11, a heat pump 12, and a heating layer pipe 13. The heating layer pipe 13 is connected to the hot water tank 11 through a heating pipeline 14. The heat pump 12 is installed on the heating pipeline 14 and is used to circulate the heating medium, which is water. The hot water tank 11 supplies water for heating, and the heat pump 12 pumps the water into the heating layer pipe 13. The heating layer pipe 13 is installed inside the oven 1 to heat the drying trays. The water in the heating layer pipe 13 eventually flows back to the hot water tank 11, forming a cycle. The heating layer pipe 13 has multiple layers, with each layer of heating layer pipe 13 corresponding to one drying tray, and the drying tray is located between the heating layer pipe 13 and the atomizing spray pipe 7.

[0024] In this embodiment, multiple atomizing nozzles 8 are spaced apart on the atomizing spray pipe 7 to increase the coverage of the water mist sprayed by the atomizing nozzles 8; a water supply valve 9 is installed on the water supply pipe 6 to control the water supply pressure.

[0025] In this embodiment, a sloping structure is formed at the bottom of the oven 1, and a drain outlet 10 is provided at the bottom of the sloping structure to drain the mist water that has settled at the bottom of the oven 1; a pressure relief valve 15 is provided on the side wall of the oven 1 to balance the internal pressure of the oven 1 after drying.

[0026] In use, place the drying trays containing the ammonium glycyrrhizate salt to be dried neatly and orderly on the heating tubes 13 inside the oven 1. Then close the oven 1 door and start the heating system, condenser 2, vacuum system 4, and other equipment to perform vacuum drying. Ethanol is collected at the condenser 2 and flows into the receiving tank 3. After vacuum drying for a certain period of time, open the water supply valve 9, and the external water supply system supplies water to the atomizing spray pipe 7. The atomizing nozzles 8 on the atomizing spray pipe 7 spray water into the drying trays in an atomized form. The atomized water and ammonium glycyrrhizate salt come into full contact, and vacuum drying continues until the ethanol residue of the ammonium glycyrrhizate salt meets the requirements.

[0027] This embodiment has a reasonable and compact structure, and is simple and convenient to operate. The entire process (except for loading) is a sealed production process. It adopts direct online atomized spray water mixing, avoiding manual water mixing during the production process, realizing continuous production, shortening the drying cycle, and thus effectively improving production efficiency.
