\ud83d\udca1 The QN Series Spherical Concentrators are specialized concentration equipment designed for heat-sensitive materials under vacuum and reduced pressure. Their one-piece stamped spherical tanks offer higher heat transfer efficiency, and they operate at low temperatures under negative pressure to produce high-density extracts in a single pass. They are widely used for the concentration of traditional Chinese medicine pastes, oral liquids, and plant extracts, as well as for the recovery of organic solvents.<\/p>\n
The Spherical Concentrator (QN Series) isVacuum-Pressure-Reducing Concentration Equipment Specifically Designed for Heat-Sensitive Materials<\/strong>The core of the system is a spherical tank formed through a single-stage stamping process. It operates under low-temperature, vacuum conditions and achieves rapid concentration of the feed solution through jacket heating and efficient gas-liquid separation. The equipment ensures uniform heating with no dead zones in heat transfer, enabling an extract specific gravity of up to 1.3\u20131.4. It is particularly suitable for traditional Chinese medicine extracts, oral liquids, and medicinal pastes.High-Concentration Concentrate<\/strong>Along with organic solvent recovery processes, these are widely used in the pharmaceutical, food, and health supplement industries.<\/p>\n The equipment consists ofSpherical concentration tank, jacket heating system, wall-scraping agitator (optional), defoamer, gas-liquid separator, shell-and-tube condenser, solvent recovery tank, vacuum system, and automatic control instruments<\/strong>Construction: Fully enclosed, hygienic design that complies with GMP clean production standards:<\/p>\n \u2705 One-piece stamped spherical tank<\/p>\n Made of 304\/316L stainless steel in a single-piece construction, with mirror-polished surfaces inside and out leaving no blind spots, ensuring residue-free cleaning and a larger heat transfer area than conventional cylindrical tanks.<\/p>\n \u2705 Full-range jacket heating system<\/p>\n Supports both steam and thermal oil as heating media, ensuring uniform heating throughout the entire chamber without localized high temperatures, thereby preventing material coking.<\/p>\n \u2705 Optional wall-scraping agitator<\/p>\n The rotating scraper continuously renews the heat exchange surface on the inner wall, effectively preventing high-viscosity pastes from sticking to the walls or coking.<\/p>\n \u2705 Multi-stage defoaming gas-liquid separation assembly<\/p>\n Equipped with a dedicated defoamer and a high-efficiency separator, this system prevents material loss and significantly improves the recovery rate of organic solvents such as alcohol.<\/p>\n \u2705 Stable vacuum system<\/p>\n Maintain a stable negative pressure of -0.06 to -0.09 MPa, lowering the boiling point of the feed solution to 45\u201365 \u00b0C to protect heat-sensitive active ingredients at low temperatures.<\/p>\n \u2705 Spherical design for efficient heat transfer and fast concentration<\/p>\n The spherical structure has a heat transfer area approximately 20% larger than that of a cylindrical tank, resulting in a faster evaporation rate and significantly shorter production cycles.<\/p>\n \u2705 Operates under vacuum at low temperatures to preserve the activity of the material<\/p>\n The entire process involves low-temperature, negative-pressure evaporation, which does not damage heat-sensitive active ingredients such as traditional Chinese medicine, enzymes, and vitamins, resulting in a higher-quality final product.<\/p>\n \u2705 High-concentration extract; the specific gravity of the extract can reach 1.3\u20131.4<\/p>\n It can produce a high-density, thick paste in a single step, meeting the requirements for the refined production of traditional Chinese medicine pastes and high-end pharmaceutical formulations.<\/p>\n \u2705 Optional wall-scraping agitator to prevent sticking and coking<\/p>\n High-viscosity paste continuously scrapes against the tank walls to facilitate heat transfer, completely eliminating the problems of material sticking to the walls and carbonization losses associated with traditional concentration tanks.<\/p>\n \u2705 Fully sanitary design, compliant with GMP standards<\/p>\n Stainless steel mirror-finish polishing, quick-opening manholes, no hard-to-clean areas, easy to clean, suitable for pharmaceutical and food cleanrooms.<\/p>\n \u2705 One machine, multiple processes; flexible functionality<\/p>\n It can simultaneously perform feedstock concentration, extract concentration, and solvent distillation and recovery; under certain operating conditions, it can be integrated with a crystallization process to accommodate diverse production needs.<\/p>\n \u2705 Compact design and easy to maintain<\/p>\n The unit has a small footprint, operates reliably with its integrated automatic control instruments, and is easy to maintain and service on a daily basis.<\/p>\n \u2705 Pharmaceutical Industry<\/p>\n Low-temperature concentration and drying of traditional Chinese medicine extracts, traditional Chinese medicine pastes, oral solutions, medicinal pastes, and medicinal wines.<\/p>\n \u2705 Food Industry<\/p>\n Low-temperature concentration of high-viscosity materials such as fruit juices, syrups, dairy products, fermented liquids, and honey.<\/p>\n \u2705 Health Supplements\/Fine Chemicals<\/p>\n Concentration of various heat-sensitive plant extracts and aqueous solutions; recovery and distillation using organic solvents such as alcohol.<\/p>\nII.
