Multi-function Positive Cone Extraction Tank

Updated: 2026-09-19

Overview

The Multi-function Positive Cone Extraction Tank is a specialized industrial equipment designed for efficient extraction processes across various industries, including pharmaceuticals, chemicals, and food production. Its conical shape ensures optimal solvent distribution and material separation, making it highly effective for extracting active compounds from raw materials. This equipment is particularly popular in traditional Chinese medicine production, where it is used to extract active ingredients from herbs. Its versatility also extends to essential oil extraction and chemical processing, where precise control over extraction parameters is crucial for product quality.

Structure and Working Principle

The extraction tank features a conical bottom design that facilitates complete drainage and efficient separation of extracted materials. The main components include the extraction vessel, condenser, solvent recovery system, and filtration layers. The conical shape promotes natural material movement during the extraction process. Operation typically involves loading raw materials into the vessel, adding solvent, and applying controlled heat and pressure. The conical design ensures thorough contact between solvent and materials, while multi-layer filtration systems separate extracted compounds from residual solids. The system often includes temperature and pressure sensors for process control and safety.

Key Features

This extraction tank stands out for its high extraction efficiency, achieved through optimized solvent circulation and temperature control systems. The conical design minimizes dead space, ensuring nearly complete material utilization and reducing solvent waste. Modern versions often include automation features such as programmable logic controllers (PLCs) for precise process control. The equipment is typically constructed from high-grade stainless steel, making it resistant to corrosion and suitable for use with various solvents. Additional features may include CIP (Clean-in-Place) systems, vacuum capabilities, and energy-efficient heating elements.

Application Areas

The primary application of this equipment is in the pharmaceutical industry, particularly for extracting active compounds from herbal materials. It's extensively used in traditional medicine production, where maintaining the integrity of natural compounds is essential. In the food industry, the tank is used for extracting flavors, colors, and nutritional compounds from plant materials. The chemical industry utilizes it for specialized extraction processes where conventional methods are ineffective. Recent applications have expanded to cannabis extraction for medicinal products, where precise temperature control is critical.

Maintenance and Precautions

Regular maintenance is crucial for optimal performance. This includes periodic inspection of seals and gaskets, cleaning of filtration systems, and calibration of control instruments. The conical design requires special attention during cleaning to prevent residue buildup in the tapered section. Safety precautions include proper grounding of electrical components, regular pressure vessel inspections, and adequate ventilation when working with volatile solvents. Operators should be trained in emergency procedures for pressure relief and solvent spills. Compatibility between construction materials and solvents should always be verified before operation.

B2B Procurement Guide

When procuring these extraction tanks, buyers should consider production capacity requirements, automation needs, and compliance with relevant industry standards (such as GMP for pharmaceutical applications). The choice between SS304 and SS316 stainless steel depends on the solvents being used. Lead times for custom configurations can be significant, so planning is essential. Many suppliers offer modular designs that allow for future upgrades. Buyers should verify after-sales support availability, including spare parts supply and technical assistance. Energy efficiency features may justify higher initial costs through long-term operational savings.
