Subcritical Water Extraction Equipment

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

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. Swe is performed in batch or continue systems but continue system is current. 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. Supercritical water processing unlike scwo the goal with supercritical water processing is to selectively break down a material yielding the desired product s.

Equipment of subcritical water extraction no commercial swe equipment is available but the apparatus is easy to construct in the laboratory. Subcritical water extraction of antioxidants from food and food by products richard todd. Supercritical water has special properties to. 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.

Subcritical water extraction swe is a new promising extraction method for bioactive compounds. Lab scale subcritical water processes are gaining interest and can be green. In this system extraction bed is fixed and flow direction is usually up to down for easily cleaning of analytes. Supercritical co2 extraction of cinnamon coffee and vanilla with dry ice duration.

Largescale subcritical water extraction swe systems are being devised but slowly. No commercial swe equipment is available but the apparatus is easy to construct in the laboratory. This process is extremely promising particularly from an environmental point of view. To accomplish this process conditions are carefully controlled so that the decomposition of the starting material is limited and directed.

Equipment of subcritical water extraction. 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. Swe is performed in batch or continue systems but continue system is current. Temperature control impacts the decomposition and optimal selectivity of products.

In all extraction methods throughput will always be a key element for improvement.
