Centrifugal Extractor for Liquid-Liquid Extraction: High Efficiency, Sealed Design & Anti-Emulsifica
2026-04-20
In modern industrial production systems, liquid-liquid extraction and separation is a core process in chemical, pharmaceutical, metallurgical, and environmental protection fields, directly determining product purity, production efficiency, and enterprise economic benefits. LIANCUI-KAIMINA's independently developed LCT series centrifugal extractors, with their core advantages such as high-speed centrifugal force-enhanced mass transfer, closed continuous operation, anti-emulsification, and strong adaptability, overcome the bottlenecks of traditional extraction equipment, including low efficiency, large footprint, and high solvent loss. They are widely used in nine major industries: chemical, pharmaceutical, pesticide, hydrometallurgy, food, environmental protection, petroleum, fragrance, and dye, becoming core equipment for green production and process upgrading in these industries.I. Centrifugal Extractor For Chemical Industry: Fine Separation, Supporting Green ChemicalsThe chemical field is the core application scenario for LCT centrifugal extractors, covering organic synthesis, fine chemicals, solvent recovery, and acid-base extraction. The equipment can efficiently separate target products from chemical reaction liquids, with a stable single-stage extraction rate exceeding 98%, and a throughput three times higher than traditional mixing and clarifying tanks. In chemical solvent recovery, the solvent loss rate is less than 0.2%, and the recycling rate exceeds 98%, significantly reducing production costs. For the purification of dye intermediates, multi-stage countercurrent extraction can increase product purity from 85% to 99.2%, solving the problems of batch instability and excessive impurities in traditional processes.II. Centrifugal Extractor For Pharmaceutical Industry: High-Purity Purification, Meeting GMP StandardsThe pharmaceutical industry has stringent requirements for product purity and production cleanliness. The LCT centrifugal extractor uses 316L stainless steel clean material and a fully enclosed structure, perfectly adapting to GMP production specifications. For example, in the synthesis of a certain type of drug intermediate, 5-stage countercurrent extraction increases purity from 88% to 99.5%, with impurity residue controlled below 0.1%. It can also treat pharmaceutical wastewater, efficiently removing organic solvents such as DMF and dichloromethane, achieving a COD removal rate of 96%.III. Centrifugal Extractor For Pesticide Industry: Continuous Production, Improving Pesticide PurityThe production of pesticide intermediates and active ingredients requires efficient separation and purification. The LCT centrifugal extractor enables continuous operation, overcoming the efficiency bottleneck of traditional batch production in reaction vessels. In the production of herbicides such as acetochlor and glyphosate, a series of acid washing, alkali washing, and multi-stage water washing processes are used to remove unreacted raw materials and impurities, increasing the purity of the organic phase to over 98%. The equipment has strong anti-emulsification capabilities and can stably process pesticide solutions containing surfactants, ensuring continuous and stable production.IV. Centrifugal Extractor For Hydrometallurgy: High-Efficiency Extraction and Separation of Rare MetalsHydrometallurgy is a key area of expertise for LCT centrifugal extractors, suitable for the extraction of metals such as copper, nickel, cobalt, lithium, and rare earth elements. In copper extraction, the single-stage extraction rate exceeds 92%; in cobalt and nickel separation, a 6-stage countercurrent extraction achieves a separation efficiency of 98%, with a total extraction rate exceeding 99.5%. The equipment is resistant to strong acids and alkalis (pH 0.5-14), can handle complex slurries and leachates, reduces metal cross-contamination, and improves resource recovery rates.V. Centrifugal Extractor For Food Industry: Gentle Extraction of Natural Ingredients, Ensuring SafetyThe food industry prioritizes natural and safe ingredients. The LCT centrifugal extractor employs gentle centrifugal separation, avoiding high-temperature damage and impurity contamination. It is used for edible oil refining, food-grade phosphoric acid purification, and the extraction of tea polyphenols and lysine. When extracting tea polyphenols, purity exceeds 98%, with a yield of over 95%. Separating lysine fermentation broth allows for rapid two-phase distribution, improving product purity and production efficiency.VI. Centrifugal Extractor For Environmental Protection Industry: Industrial Wastewater Treatment and Resource RecoveryIn the environmental protection field, the LCT centrifugal extractor is a powerful tool for treating highly challenging industrial wastewater. For chemical, pharmaceutical, and dyeing wastewater, it can extract and remove pollutants such as phenols, aniline, and organic oils, reducing the oil content of the effluent to below 9 ppm. When treating pesticide wastewater, the purification rate exceeds 99%. Simultaneously, it recovers valuable substances such as heavy metals and organic acids from the wastewater, turning waste into treasure.VII. Centrifugal Extractor For Petrochemical Industry: Oil Refining and Cleaner ProductionIn the petrochemical industry, it is used for lubricating oil refining, diesel desulfurization, biodiesel separation, and refinery wastewater treatment. For treating naphthenic acid wastewater from refineries, three-stage extraction achieves a COD removal rate of 92%. Separating biodiesel and glycerol reduces the phase separation time to within 0.5 seconds, occupies only 1/10 the space of traditional equipment, and reduces energy consumption by 60%.VIII. Centrifugal Extractor For Fragrance Industry: High-Efficiency Extraction of Natural Fragrances, Preserving ActivityFragrance and flavor production requires gentle separation. The LCT centrifugal extractor can extract vanillin, plant essential oils, etc. Multi-stage countercurrent extraction improves mass transfer efficiency by 3 times, reduces emulsification, and achieves a solvent recovery rate of over 98%. Separating fragrance intermediates increases purity to over 99%, ensuring pure aroma.IX. Centrifugal Extractor For Dye Industry: Intermediate Purification, Improving Color Fastness and PurityIn dye production, the purity of intermediates affects color and color fastness. LCT centrifugal extractors remove salts, unreacted raw materials, and byproducts from dye intermediates, improving purity and batch stability. They also treat dye wastewater, recover useful dye components, and reduce pollution and raw material waste.
From small-scale laboratory trials to large-scale industrial production, LCT centrifugal extractors, with their core values of high efficiency, stability, environmental friendliness, and energy saving, provide customized separation solutions for nine major industries, helping companies reduce costs, increase efficiency, and achieve green transformation, making them the preferred equipment in the field of industrial extraction and separation.Contact us today for a free process evaluation and pilot test support.
