Scheme of a trickle-bed reactor. A trickle-bed reactor (TBR) is a chemical reactor that uses the downward movement of a liquid and the downward (co-current) or upward (counter-current) movement of gas over a packed bed of particles.
An airlift pump is a pump that has low suction and moderate discharge of liquid and entrained solids. The pump injects compressed air at the bottom of the discharge pipe which is immersed in the liquid.
A continuous fermentation process for the production of Fusarium venenatum biomass (marketed as Quorn) was developed using a 40 m 3 (1,400 cu ft) air-lift fermenter. [ 6 ] [ 7 ] During the 1960s, it was predicted that by the 1980s there would be a shortage of protein-rich foods.
Strategic airlift is the use of military transport aircraft to transport vehicles, materiel, weaponry, or personnel over long distances. Typically, this involves airlifting the required items between two airbases that are not in the same vicinity.
The temperature of the fermentation medium is maintained by a cooling jacket, coils, or both. Particularly exothermic fermentations may require the use of external heat exchangers. Nutrients may be continuously added to the fermenter, as in a fed-batch system, or may be charged into the reactor at the beginning of fermentation.
Algae bioreactor Representation of a bubble column reactor.. A bubble column reactor is a chemical reactor that belongs to the general class of multiphase reactors, which consists of three main categories: trickle bed reactor (fixed or packed bed), fluidized bed reactor, and bubble column reactor. [1]
The simplest approach is the redesign of the well-known glass fermenters, which are state of the art in many biotechnological research and production facilities worldwide. The moss reactor for example shows a standard glass vessel, which is externally supplied with light.
An airlift is device based on a pipe, used in nautical archaeology to suck small objects, sand and mud from the sea bed and to transport the resulting debris upwards and away from its source. It is a type of suction dredge .
