The invention relates to the technical field of concentration equipment, and particularly discloses equipment and a method for concentrating a ginsenoside extracting solution. A concentration unit; a dispersing unit; an eccentric suction unit; and a heating unit. According to the invention, through circumferential stirring of the dispersing unit and reciprocating circulation action of the eccentric suction unit, multi-dimensional space turbulent flow is realized for extracting solutions of different levels in the concentration container, the layering phenomenon of heavy component sinking and light component floating is forcibly broken, and high homogenization of the extracting solutions in the whole concentration process is ensured, so that the concentration effect consistency is improved, and the concentration efficiency is improved. The stability of the content of ginsenoside in different batches of products is ensured; meanwhile, heat is quickly and uniformly distributed in the liquid due to continuous physical disturbance, so that degradation or charring of a heat-sensitive ginsenoside component caused by local overheating is avoided, and the activity of a target component is reserved to the greatest extent.

The utility model discloses a silicone sealant production device relates to sealant production technical field, including the reation kettle, the inlet of reation kettle is respectively through pipeline communication to have silica rubber jar, white carbon black jar, calcium carbonate jar, anti -settling agent jar, plasticizing agent jar, crosslinking agent jar and catalyst jar, the outlet of reation kettle is through pipeline communication to have double screw extruder, the outlet of double screw extruder is through pipeline communication to have product jar. Through adding anti -settling agent (such as organic bentonite) to reation kettle, with silica rubber, filler (white carbon black, calcium carbonate), plasticizing agent synchronous mixing, anti -settling agent can form three -dimensional net structure, prevent filler and settle in the subsequent storage and construction process, and the uniformity of silicone sealant is good, and the product quality is high.

This invention provides an extract of *Lycopodium clavatum*, its preparation method, and its application. The preparation method includes the following steps: *Lycopodium clavatum* powder is extracted with alcohol; the resulting extract is concentrated under reduced pressure to obtain a crude extract; the crude extract is centrifuged, and supernatant I is collected; the precipitate is reconstituted and centrifuged again to collect supernatant II; supernatant I and supernatant II are combined to obtain a purified solution; the purified solution is eluted in stages using a macroporous resin, and the last eluent is collected, concentrated, and dried to obtain the *Lycopodium clavatum* extract. The preparation method provided by this invention can effectively enrich saponins, flavonoids, polyphenols, and lycoclavanin in *Lycopodium clavatum*, allowing for precise control and stable content of active ingredients; the prepared *Lycopodium clavatum* extract has good antioxidant and soothing effects and can be used in cosmetics.

The oil supply bin of the electronic atomization equipment can automatically inject oil into the oil storage bin.

The present application relates to a nicotine pellet composition, a nicotine pellet pouch and a preparation method thereof. The nicotine pellet composition comprises nicotine, a blank pellet core, a binder, a sweetener, a pH regulator, cellulose and cellulose derivatives, a high-molecular coating material, a lubricant, a flavoring agent and a solvent. The blank pellet core is loaded with the nicotine, and the high-molecular coating material forms a single layer or multiple layers of drug loading or coating on the blank pellet core. When the high-molecular coating material forms multiple layers of drug loading or coating, it comprises, from inside to outside, a separation layer, a drug-containing layer, a protective layer and a drug-loading layer. The present application provides a nicotine pellet composition and a nicotine pellet pouch with good fluidity, stable nicotine release and stable aroma release, which can be used for the treatment of smoking cessation or nicotine dependence.
