According to the invention, in a reaction chamber, which constitutes a component of a process installation for obtaining foodstuffs or foodstuff components, biological products in harvested form that are whole or in pieces are subjected to pulsed electric fields as they traverse said chamber. Said electric fields form pores in the cell walls, i.e. irreversibly open the latter, thus making the cell contents more easily accessible. This is achieved by electrode groups, which can be impinged by a high voltage and are located in a longitudinal zone of the wall of the reactor zone along the traversing axis of the process material and by earthed electrodes located in an opposing longitudinal zone. Each electrode group is connected to a rapid electric energy accumulator, such as for example a Marx generator, by means of a switch, in order to rapidly establish electric fields of multiple directions between the electrodes that are to be currently charged and the earthed electrodes. There is only ever one group of electrodes at high voltage for a predetermined time period. |
