The procedure for the treatment of vital plant, animal cells and/or cell clusters with pulsed electric energy for the disruption of the cells and/or cell membrane, comprises perforating cell membranes in pumpable and agglomerate product in reversible and irreversible manner through a poration reactor by adjusting a high current density and optimal surface charge density. The current density (J) of 50-500 kA/m2> is reached through initiating a unipolar or bipolar current pulse in sufficient pulse voltage. The surface charge density in the reaction zone of each energy impulse is 0.5-2 C/m2>.

The current density (J) of 50-500 kA/m2> is reached through initiating a unipolar or bipolar current pulse in sufficient pulse voltage. The surface charge density in the reaction zone of each energy impulse is 0.5-2 C/m2>. The product to be treated, pumpable and agglomeratable is directed at stationary electrode system and is immersed in a fluid and/or the cell consists of cell fluid, returned activated cell fluid or aqueous fluid emerged through crushing. The conductivity of the fluid is 0.5-5 mS/cm and is adjusted to 0.1-20 mS/cm. Pumpable meat and fish product, plant product such as fruit and vegetable mash and/or agglomerated product are treated. A system pressure in the reaction zone is adjusted by over pressure of 0-10 bar in the mash with gas inclusion. The over pressure in the agglomerated product is 0-0.5 bar. A limited pulse quantity of 20-60 pulse is delivered to each volume element and between the pulses, a period of 20-40 milliseconds is passed. A continuous product throughput is reached to 5,000-15,000 kg/h and a continuous treatment of pumpable and agglomerated product is realized. An independent claim is included for a poration reactor for pumpable and agglomerate product. |
