Solvent Extraction Equipment - Professional Solution for Liquid-Liquid Separation
Xi'an Bioland Instrument Co., Ltd. sells professional solvent extraction equipment that is designed to get the most out of plants and separate compounds. With more than 15 years of experience making things, our systems use ultrasonic-assisted extraction technology, which makes them 50–500% more efficient than other ways. Our product has two different types of condensers, PLC automatic control, and extraction temperatures kept between 40°C and 60°C to protect active ingredients that are sensitive to heat. Ultrasonic Assisted Extraction (UAE), hot reflux, organic solvent extraction (OSE), and alcohol precipitation are some of the extraction methods that the tools can handle. When compared to old methods, extraction processes take only 24 to 40 minutes to finish, which is over 66% less time. You can get all of our systems with full explosion-proof approval, and they all meet GMP/FDA standards.

Working Principle
Our method uses advanced mass transfer concepts for moving mass from solids to liquids and from liquids to solids.
When the raw materials go into the extraction tank, the process starts. Solvent is added at a fixed temperature and rate of flow. Ultrasonic waves (optional) cause cavitation effects, which break down cell walls and speed up the breakdown of active compounds.
As the blend moves through the reactor, the ideal temperature is kept. Different levels of solubility cause active ingredients to move from the solid structure to the solution phase.
The liquid phase goes through precision filtering to get rid of the particles after extraction. The extracted material is then sent to the concentration module, where extra liquid is removed by low-temperature vacuum evaporation.
Recovered liquid goes back into the system, which lowers the cost of the materials. The pure extract is gathered so that it can be processed further or put directly into packages.
Critical factors are constantly being checked by temperature sensors, pressure gauges, and flow meters. The PLC system changes the speeds of heating, cooling, and mixing on its own to keep the extraction conditions perfect throughout the cycle.

Process Flow
Step 1: Material Loading
After prep work like washing, breaking, or drying as needed, the raw plant materials are put into the extraction tank.
Step 2: Solvent Addition
Based on the properties of the material, food-grade ethanol, water, or other acceptable liquids are added in specific amounts.
Step 3: Ultrasonic Extraction

When equipped, ultrasonic generators work, making tiny bubbles that make cell walls more permeable and speed up the breakdown process.
Step 4: Temperature-Controlled Extraction
Correct temperatures are kept by heating devices. The liquid is spread evenly across the material bed by circulation machines.
Step 5: Filtration
Bag filters, plate filters, or vacuum filters are used in multiple steps to remove solids and other impurities from the extract.
Step 6: Pay attention
The liquid that has been clarified goes into the vacuum concentration unit. There, it becomes smaller through slow evaporation while the active chemicals are kept.
Step 7: Solvent Recovery
This device collects the vaporized solvent, melts it down, and sends it back to the holding tanks so it can be used again.
Step 8: Collection & Discharge
Clean valves let concentrated extract flow into collection jars so it can be used in later steps of the process.

Quality Certification

The factory where we make things is certified by the ISO quality control system. Before they are sent out, all units of solvent extraction equipment go through strict factory acceptance testing (FAT).
When machinery and pressure tanks get CE approval, it means they meet European safety standards. Our plans follow the ATEX guidelines for tools that will be used in areas that could be explosive.
FDA food-grade standards are met by materials that come into touch with process fluids. The methods for welding are based on ASME standards, and full documentation for each weld is provided.
All stainless steel parts in each unit come with mill test records and a full material tracking package. Pressure vessels are tested hydrostatically at 1.5 times their original pressure, and the findings are recorded.
With every system, we include full operation instructions, electrical schematics, P&ID diagrams, and servicing schedules. Our service package includes help with installation and training for operators.
FAQ
Q: What's the difference between ultrasonic extraction and traditional methods?
A: Ultrasonic technology uses high-frequency sound waves to create cavitation bubbles. This mechanical action breaks cell structures more efficiently than heat alone. You'll see faster extraction times, lower temperatures, and higher yields of heat-sensitive compounds.
Q: Can you process materials with high oil content?
A: Yes. We design the system with appropriate filtration and separation modules. For high-oil materials, we recommend configuration with centrifugal separation or extended settling stages to cleanly separate the extract phase.
Q: What solvents can your equipment handle?
A: Our systems accommodate water, ethanol, methanol, acetone, hexane, and other common extraction solvents. For aggressive solvents, we specify 316L stainless steel construction and appropriate seal materials. Always confirm your solvent with our engineers during specification.
Q: How do you ensure consistent batch quality?
A: The PLC control system maintains precise temperature, time, and mixing parameters. Recipe storage allows you to recall proven settings. Automated monitoring eliminates operator variation between batches.
Q: What maintenance does the equipment require?
A: Regular inspection of seals, gaskets, and heating elements. The CIP system simplifies internal cleaning. Ultrasonic transducers should be inspected every 3,000 hours. We provide a detailed maintenance schedule with recommended spare parts lists.
Q: Can the system be integrated into existing production lines?
A: Absolutely. We design interface points for upstream material handling and downstream concentration equipment. Our engineering team will review your facility layout and provide integration recommendations.
Q: What's your typical delivery time?
A: Stock configurations ship within 5–7 business days. Custom-designed systems require approximately 30 days from order confirmation. We'll provide weekly progress updates throughout fabrication.
Q: Do you offer installation and training?
A: Yes. Our technical team can travel to your facility for installation supervision, commissioning, and operator training. Alternatively, we provide detailed video guidance and remote support for straightforward installations.
