Steam Explosion Sample Conditioners – 5404

Steam Explosion Sample Conditioner

In recent years we have received a number of inquiries for reactors to work with various types of biomass. Some of the first of these were for use with wood pulp. Then requests for reactors to work with wood chips, corn stover (stalks and cobs) and other cellulosic materials have become more common. While their moisture contents may be high by weight percentage, these materials cannot be agitated effectively in a conventional vertical stirred reactor. Rather, we have found that vapor explosion can be an effective option to perform fiber cracking. These reactors can be manufactured in volumes ranging from two liters to 5 gallons (18.5 liters), with the most popular size being two liters. These systems include three basic sub-systems: 1- A high pressure Steam Generator; 2- The explosion Reactor; 3- , The expansion Cyclone Chamber. These systems are connected by a central control system which monitors and controls the working parameters. A high speed actuated ball valve is used to open the main sample vessel to expand the biomass to the cyclone chamber and thus crack the biomass fibers.
