Compatibility of Rotary Evaporator (20L) with Black Garlic Extraction

Yes, the Rotary Evaporator (20 Litre, electric lift) Vacuum distillation evaporator can be used with Black Garlic, specifically for the process of creating Black Garlic Extract.

How it is used with Black Garlic:

A Rotary Evaporator is not used to "make" black garlic (the aging process), but rather to process it into a concentrated liquid or powder extract:

1. Extraction: Black garlic is typically soaked in a solvent (such as water or ethanol) to draw out its active compounds.
2. Filtration: The solids are filtered out, leaving a liquid extract.
3. Concentration (The Rotovap's Role): The liquid extract is placed in the 20L evaporating flask. The machine uses a vacuum to lower the boiling point of the solvent, allowing it to evaporate at a low temperature (e.g., 40-50°C). This protects heat-sensitive active ingredients like S-Allyl-L-Cysteine (SAC), which are found in high concentrations in black garlic.

Key Benefits for Black Garlic Processing:

• Preservation of Nutrients: Since black garlic is valued for its antioxidant properties, using vacuum distillation prevents the degradation of these compounds that would occur with high-heat boiling.
• Efficiency: The 20-liter capacity is suitable for medium-scale production of extracts like WeightCare™ Black Garlic Extract or InflamCare™ Black Garlic Extract.
• Solvent Recovery: If you use ethanol for extraction, the machine will collect the evaporated ethanol in the receiving flask so it can be reused.

Important Considerations:

• Vacuum Pump: This machine requires a vacuum pump (such as a Water Aspirator) to operate, which is sold separately.
• Demonstration: It is highly recommended to see a demonstration of the machine at the company's location before purchasing to ensure it meets your specific production needs.
