50L Ultrasonic Extraction Machine Plant Oil Extraction Integrated For Fast Botanical Infusions

This 50L ultrasonic extraction system combines traditional solvent maceration with high-intensity ultrasound cavitation to drastically reduce extraction times. Designed for the rapid production of herbal tinctures, infused oils, and botanical glycerites, this unit achieves in 30-60 minutes what traditionally requires 2-6 weeks of cold maceration. The system features a triple-layered stainless steel tank with integrated submersible ultrasonic transducers and a temperature-controlled jacket. It is the modern solution for herbalists, skincare formulators, and manufacturers seeking to improve throughput without compromising extract quality.

Traditional herbal oil extraction is slow. Whether making calendula oil in olive oil or extracting cannabinoids in MCT oil, the process relies on passive diffusion. This inefficiency ties up working capital in inventory and storage space for weeks. Heat-assisted extraction speeds this up but degrades chlorophyll and produces a burnt, bitter taste. The market demands a technology that accelerates mass transfer without applying thermal energy that damages delicate actives. Producers need to turn over batches faster to meet e-commerce demand for fresh, small-batch wellness products.

Ultrasonic extraction uses acoustic cavitation—the formation and violent collapse of microscopic bubbles in the liquid medium. These implosions create micro-jets that physically tear open plant cell walls, releasing intracellular oil and actives instantly into the carrier solvent. The process occurs at ambient or slightly warm temperatures (≤40°C), preserving the integrity of heat-labile vitamins and enzymes. The result is a more complete extraction profile with higher yields of antioxidants and a fresher, greener aroma. The 50L capacity allows for commercial production of infusions in a single shift.

This unit excels in the production of CBD/THC-infused MCT oils, providing rapid, cold-infusion that preserves the entourage effect. Herbalists use it to create potent St. John's Wort oil (red oil) and Arnica massage oil in hours. Skincare manufacturers employ it to infuse botanicals like green tea, chamomile, and comfrey directly into jojoba or sunflower oil for serums and balms. It is also used in the food industry to create fast-infused flavored oils (garlic, rosemary, chili) with exceptional pungency.

Plant material and carrier oil (or solvent) are loaded into the tank. The ultrasonic generator sends high-frequency electrical signals to the transducers, which vibrate and send pressure waves through the liquid. These waves create cavitation bubbles near the plant surface. When these bubbles collapse, they release a high-energy micro-jet and local temperature spike (microscopic only) that blasts the cell contents into the surrounding oil. The process is repeated for a preset cycle time, after which the mixture is filtered through a mesh basket or plate filter.

Selecting an ultrasonic system depends on the viscosity of your carrier oil. High-viscosity oils (like castor or thick olive oil) dampen cavitation; you may need a higher amplitude setting or a pre-heated jacket to thin the oil slightly. Second, consider the particle size of your herb; very fine powders can settle and dampen the transducers, so a recirculation pump accessory is recommended for these applications. Third, check the duty cycle of the transducers; for 50L units, a 50% duty cycle (on/off pulsing) is standard to prevent overheating. Fourth, verify the material compatibility of the transducer face—ours are PTFE coated to prevent corrosion from acidic botanicals.

Q: Does the ultrasound degrade the cannabinoids or terpenes?
A: No. The process is non-thermal. The cavitation is a physical, not thermal, effect. Studies show ultrasound-assisted extraction retains a higher percentage of volatile monoterpenes compared to heat-assisted methods.

Q: Can I use flammable solvents like ethanol in this machine?
A: Yes, but the system MUST be installed in a properly ventilated, C1D2 rated hazardous location. The electrical enclosure is purged and sealed. We strongly recommend using the system with non-flammable oils for safety unless your facility is explosion-proof rated.

Q: How do I filter the herb particles out after extraction?
A: We offer an optional in-tank stainless steel mesh basket (200-400 micron) that contains the herb. This allows the oil to circulate freely while keeping the solids contained for easy removal and pressing.
