The Alcohol Precipitation Tank (commonly known as an ethanol settling tank) is critical equipment in pharmaceutical production for solid-liquid separation and liquid purification. Manufactured from high-grade SUS304 stainless steel, the unit consists of an elliptical head, a conical bottom, and a high-efficiency agitator. By adding ethanol to the liquid extract—often processed by a vacuum alcohol evaporator—it utilizes the solubility differences of various substances to precipitate non-alcohol-soluble impurities like starch and proteins, effectively refining the medicinal solution.

Core Value Propositions

---

• Material Excellence & Compliance: Fabricated from premium SUS304 stainless steel with a mirror-polished interior (Ra ≤ 0.4μm). Equipped with a high-pressure CIP system, it fully meets CGMP and FDA hygiene standards.
• Intelligent Decanting Design: Features a specialized floating-ball decanter that automatically tracks the liquid level. It stops precisely at the sludge interface, ensuring maximum recovery of clear supernatant without human error.
• Explosion-Proof Safety: Specifically engineered for ethanol-rich environments, all transmission components utilize reliable mechanical seals and explosion-proof drive systems for total operational security.
• Superior Thermal Control: The jacketed vessel is designed for chilled brine or cooling water circulation, supporting the low-temperature “freeze-precipitation” required for optimal pharmaceutical clarity.

Primary Application Scenarios

---

Traditional Medicine Refining: Effectively removes starch, proteins, and non-alcohol-soluble impurities from water-based extracts after vacuum evaporation.

Dual-Direction Precipitation: Highly versatile for both alcohol precipitation of water extracts and water-based precipitation of alcohol extracts to isolate complex solid-phase impurities.

Nutraceutical & Oral Liquid Production: Significantly enhances the transparency and shelf-life stability of botanical extracts, ensuring a premium final product appearance.

Fine Chemical & Dye Processing: Suitable for both room-temperature and cryogenic sedimentation of various industrial suspensions to achieve high-efficiency separation.

Solutions to Critical Technical Challenges

---

• Enhancing Product Transparency: Removes micro-impurities and colloidal proteins that bypass traditional filtration, solving the “cloudy liquid” issue in pharmaceutical extracts.
• Preventing Sediment Clogging: Sticky or hardened residues often block discharge ports. Our system incorporates a steam-assisted softening function to liquefy compacted sludge for rapid cleaning.
• Eliminating Material Loss: The automatic decanter prevents the accidental discharge of valuable clear liquid, maximizing the yield of active pharmaceutical ingredients (APIs).
• Maximizing Investment ROI: We offer a “One Agitator, Multiple Vessels” configuration, allowing a single motorized tank to serve multiple static settling tanks, drastically reducing energy and equipment costs.
