Chemical reactions can be enabled or accelerated by catalysts. The breakdown reaction of dissolved saccharose in glucose and fructose is the intended use of CRE-3303. The reactant (saccharose solution) is moved from a tank into the reactor’s bottom by a peristaltic pump. In the reactor, the catalyst appears as a permanent bed. The fixed bed is passed through by the saccharose solution. Saccharose breaks down into glucose and fructose during the process. The catalyst quickens the process, resulting in a higher yield of the finished product (a glucose/fructose mixture). In a tank, the product is collected.
It is possible to compare different catalysts using three reactors. Exchanger resin is employed as the chemical catalyst. The biological catalyst invertase comes highly recommended. A controlled heating water circuit also makes it possible to examine how temperature affects the reaction. A photometer that has been specially designed for the unit is provided to measure the amount of glucose present in the product. The photometer data are uploaded to a PC where software evaluates them (optional).
