Description

Technical Field

[0001] The utility model relates to the technical field of dipotassium glycyrrhizinate production, in particular to a dipotassium glycyrrhizinate secondary concentration device. Background Art

[0002] Dipotassium glycyrrhizinate is the dipotassium salt of glycyrrhizic acid. It has a special sweet taste, good water solubility, pure taste, and has multiple functions such as antibacterial, anti-inflammatory, detoxification, anti-allergy, and deodorization. It is widely used in the pharmaceutical, cosmetics, daily chemicals, food and other industries.

[0003] At present, the production of dipotassium glycyrrhizinate mainly uses licorice as raw material, which is extracted with water and then completely neutralized with potassium hydroxide or potassium carbonate. In the post-treatment process, low-concentration ethanol is used to dissolve the crude dipotassium glycyrrhizinate, and after passing through a cation exchange resin and decolorization, it is concentrated and finally spray-dried to obtain the dipotassium glycyrrhizinate product. However, in the concentration process, only most of the ethanol can be removed. Since the ethanol in the concentration process is continuously reduced, the stirring speed of the agitator will be reduced, thereby greatly reducing the concentration efficiency, which is not conducive to the production of dipotassium glycyrrhizinate. The extension of the concentration time will also lead to the risk of microbial contamination of the material in the concentration kettle.

[0004] In view of this, it is necessary to provide a device for secondary concentration of the primary concentrated material of dipotassium glycyrrhizinate. Utility Model Content

[0005] In order to overcome the above technical defects, the utility model provides a dipotassium glycyrrhizinate secondary concentration device, which can further remove ethanol in the dipotassium glycyrrhizinate primary concentrated material, and can obtain a concentrated material with a temperature of 18 to 22°B`, which is beneficial to improving the concentration efficiency of the dipotassium glycyrrhizinate material and reducing the risk of the dipotassium glycyrrhizinate material being contaminated by microorganisms.

[0010] Furthermore, it also includes a sterile gas respirator, the output end of which is connected to the discharge port of the concentration kettle for replenishing sterile gas into the concentration kettle.

[0011] Furthermore, the sterile gas respirator includes a first breathing valve and a sterile gas supply mechanism, the output end of the first breathing valve is connected to the discharge port of the concentration kettle, and the output end of the sterile gas supply mechanism is connected to the input end of the first breathing valve.

[0012] Furthermore, the sterile gas supply mechanism includes a sterilization box and an air filter box, the air filter box is connected to an air inlet pipe for introducing external air into the air filter box, the air outlet of the air filter box is connected to the air inlet of the sterilization box, and the air outlet of the sterilization box is connected to the input end of the first breathing valve.

[0013] Furthermore, the ethanol collection tank is connected to a second breathing valve, an output end of the second breathing valve is connected to the ethanol collection tank, and an air outlet of the sterilization box is connected to an input end of the second breathing valve.

[0014] Furthermore, an ultraviolet lamp is arranged in the sterilization box.

[0015] Furthermore, the air filter box is filled with activated carbon.

[0016] Furthermore, the concentration kettle is provided with a stirrer.

[0017] Furthermore, the vacuum pump is any one or any combination of a Roots vacuum pump, a rotary vane vacuum pump, and a sliding valve vacuum pump.

[0018] Furthermore, the condenser is at least one of a shell-and-tube heat exchanger, a coiled-tube heat exchanger, a shell-and-tube heat exchanger, a basin-and-ridge heat exchanger, and a fin-and-tube heat exchanger.

[0019] The beneficial effects of the utility model are as follows: 1. The utility model vacuumizes the concentration kettle, which is beneficial to removing a small amount of ethanol in the primary concentrated material and reducing the influence of ethanol residue on the subsequent production process of dipotassium glycyrrhizinate; 2.

The input of sterile gas is beneficial to rolling the material in the concentration kettle and improving the concentration efficiency.

The utility model arranges an ultraviolet lamp in the sterilization box , which can play a sterilization role. Activated carbon is arranged in the air filter box to filter dust and impurities in the air and play a purification role.
