Subcritical Water Extraction Equipment

Supercritical water has special properties to.

Subcritical water extraction equipment.

In this system extraction bed is fixed and flow direction is usually up to down for easily cleaning. 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. This process is extremely promising particularly from an environmental point of view. Supercritical co2 extraction of cinnamon coffee and vanilla with dry ice duration.

Supercritical water processing unlike scwo the goal with supercritical water processing is to selectively break down a material yielding the desired product s. Swe is performed in batch or continue systems but continue system is current. Temperature control impacts the decomposition and optimal selectivity of products. 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.

However the major challenge among the whole process lies in this step which account for 50 80 of the total production cost in terms of energy and equipment. To accomplish this process conditions are carefully controlled so that the decomposition of the starting material is limited and directed. In this system extraction bed is fixed and flow direction is usually up to down for easily cleaning of analytes. Equipment of subcritical water extraction.

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. 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. No commercial swe equipment is available but the apparatus is easy to construct in the laboratory.

In all extraction methods throughput will always be a key element for improvement. Subcritical water extraction swe is a new promising extraction method for bioactive compounds. Academia industry cooperation is essential for the viable scale up of swe systems. 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.

Lab scale subcritical water processes are gaining interest and can be green.
