Abstract

sistema de controle de fermentador, método para controlar aaltura da coluna de líquido em um fermentador e método para reduzir o consumo de aditivo em um fermentador. a invenção compreende um ou mais dispositivos de medição de fração de volume de gás operativamente conectados a um ou mais controladores e um ou mais mecanismos de desaeração que recebem sinais de controle de um ou mais controladores e executam um ato no sistema, como por controlar um nível de desaeração química em alguma parte do sistema de fermentação. em uma concretização, o mecanismo de desaeração é uma bomba de alimentação antiespumante que bombeia química antiespumante em uma linha de alimentação do fermentador em resposta à fração de volume de gás medida no circuito de recirculação do fermentador, em uma quantidade determinada pelo controlador como eficaz para reduzir a formação de espuma e diminuir a altura do colmou no fermentador.fermenter control system, method for controlling the height of the liquid column in a fermenter and method for reducing additive consumption in a fermenter. The invention comprises one or more gas volume fraction measuring devices operatively connected to one or more controllers and one or more deaeration mechanisms that receive control signals from one or more controllers and perform an act on the system, such as by controlling a level of chemical deaeration in some part of the fermentation system. in one embodiment, the deaeration mechanism is a defoaming feed pump that pumps defoaming chemical into a fermenter feed line in response to the measured gas volume fraction in the fermenter recirculation circuit, in an amount determined by the controller to be effective for reduce foaming and decrease the height of thatched in the fermenter.
