BioRac I

The jacket is provided with automated secondary loop temperature control system. A PT 100 temperature sensor is provided on the lower sidewall of the fermentor through a 25 mm, inclined port. The second- ary loop consists of a circulation line with temperature sensors, heat exchangers, safety relief valve, pressure gauge, flow switch, circulation pump for heating and cooling the circulating fluid. The external loop is provided with valves for steam inlet, chilled water inlet, normal water inlet, chilled water outlet, normal water outlet, drain valve and jacket condensate drain valve. Steam is automatically introduced into the jacket for full vessel sterilization. Raising temperature during process using steam is regulated by jacket and vessel temperature sensors. The chilled water inlet and outlet valves are automatically operated for cooling the vessel after empty or full vessel sterilization or for reducing temperature during process. Empty vessel sterilization is achieved by direct clear steam introduction into the fermentor through automated diaphragm valve. A temperature sensor is provided at the bottom outlet line above steam rap to monitor and control the empty vessel sterilization temperature.
