Temperature Control of a Solid State Cultivation Deep Bed Reactor

An internal cooling water coil was introduced into a deep bed reactor system and evaluated on its potential as an effective heat removal strategy. Three operating treatments were investigated: cooling water operation based on a temperature v threshold of 30°C, timed operation of ten-minute intervals with out a lag, and timed operation often-minute intervals with a lag. The treatments were assessed by their effects on enzyme yield, maximum temperature, heating rate, cooling rate, and gradients within the substrate bed during the cultivation of Trichoderma longibrachiatum for xylanase production.
