2000L Stainless Steel Extractor for Herbal Medicine

Upside-down taper type extracting tank The appearance is small at the top and big at the bottom, with the shape of upside-down taper.The most prominent features are convenient residue discharging and lower construction space.	Normal taper type extracting tank (traditional type) It takes smaller space, so it is widely used in extracting workshops. Bottom heating is provided on the residue discharging door, which makes the extraction of medicine materials more complete.
Straight cylindrical type extracting tank With long and thin appearance, it takes larger space, which benefits heat transfer and medium transfer,so that the leaching and heating time is shortened, and the extraction efficiency is enhanced. It is suitable for alcohol extraction and percolation systems.	Mushroom type extracting tank The appearance is big at the top and small at the bottom, with the shape of mushroom. The top is big so that the boiling has large buffering space without running away of materials. The bottom is small so that the heat transfer of medicine liquid is rapid, the heating time is short and the extraction efficiency is higher.

Product Overview

The 2000L Stainless Steel Extractor for Herbal Medicine sets a new benchmark in natural product extraction, combining traditional herbal processing wisdom with advanced engineering technology. This industrial-scale extraction vessel is constructed with 316L stainless steel throughout all product contact surfaces, featuring a Ra 1.6μm sanitary polish that ensures purity while resisting corrosion from botanical acids and solvents. With a nominal capacity of 2000L and working volume of 1600L, it efficiently processes large batches of medicinal herbs while maintaining 95%+ active ingredient retention – a 20% improvement over conventional extraction methods. The system integrates multiple extraction technologies including reflux, decoction, and ultrasonic-assisted extraction, controlled via a PLC system with recipe storage for different herbal formulations. Fully compliant with EU 2025/351 regulations and FDA CFR 21 Part 177 standards, it meets global requirements for herbal medicinal product manufacturing.

FAQ

What extraction efficiency can be expected?

The system typically achieves 90-95% extraction efficiency for targeted compounds, depending on material type. This represents a 15-20% improvement over conventional extraction methods due to the combined ultrasonic and reflux technology.

How long does a typical extraction cycle take?

Cycle times vary by material but generally range from:

• 2-3 hours for leaves and flowers

• 3-5 hours for roots and rhizomes

• 4-6 hours for woody materials

The PLC system stores optimized recipes for common herbs to minimize setup time.

What solvents are compatible with the extractor?

The 316L stainless steel construction is compatible with:

• Aqueous solvents (water, glycerin, propylene glycol)

• Ethanol and other alcohols (up to 95% concentration)

• Hydroalcoholic mixtures

• Food-grade organic solvents (hexane, ethyl acetate)

Specialized seals are available for stronger solvents on request.

How is cleaning performed between batches?

The integrated CIP system performs automated cleaning cycles:

• Pre-rinse with purified water

• Alkaline wash (80°C, 2% NaOH solution)

• Acidic rinse (0.5% nitric acid)

• Final rinse with WFI (Water for Injection)

Complete cleaning validation documentation is provided.
