Subcritical Water Extraction Equipment

Tournaire group s equipment division designs and manufactures pilot units or turnkey industrial installations adapted to the specific needs of users.

Subcritical water extraction equipment.

No commercial swe equipment is available but the apparatus is easy to construct in the laboratory. Subcritical water extraction swe is a new promising extraction method for bioactive compounds. In this system extraction bed is fixed and flow direction is usually up to down for easily cleaning. To accomplish this process conditions are carefully controlled so that the decomposition of the starting material is limited and directed.

Lab scale subcritical water processes are gaining interest and can be green. For example the cannabissfe a supercritical co 2 extraction system from supercritical fluid technologies is able to perform both at subcritical for terpenes and supercritical levels for cannabinoids with simple setting adjustments flexibility and scalability in throughput are always. Conventionally carotenoid extraction is required a dehydration process of microalgal biomass in order to achieve dried algal powder with water content no more than 10. Subcritical water extraction of antioxidants from food and food by products richard todd.

Supercritical co2 extraction of cinnamon coffee and vanilla with dry ice duration. Superheated water is liquid water under pressure at temperatures between the usual boiling point 100 c 212 f and the critical temperature 374 c 705 f it is also known as subcritical water or pressurized hot water superheated water is stable because of overpressure that raises the boiling point or by heating it in a sealed vessel with a headspace where the liquid water is. Swe is performed in batch or continue systems but continue system is current. Supercritical water processing unlike scwo the goal with supercritical water processing is to selectively break down a material yielding the desired product s.

In all extraction methods throughput will always be a key element for improvement. Equipment of subcritical water extraction. Equipment of subcritical water extraction no commercial swe equipment is available but the apparatus is easy to construct in the laboratory. Swe is performed in batch or continue systems but continue system is current.

Academia industry cooperation is essential for the viable scale up of swe systems. Subcritical water is defined as the water that maintains its liquid state under adequate pressure at temperature between the boiling point 100 c and critical point 374 c. Largescale subcritical water extraction swe systems are being devised but slowly. Temperature control impacts the decomposition and optimal selectivity of products.

In this system extraction bed is fixed and flow direction is usually up to down for easily cleaning of analytes.
