Electroplasmolysis of Biological Raw Materials and Apparatus for its Usage


Electroplasmolysis is a process of the treatment of biological raw materials by the electric current, during which there is the exfloitation of the protoplast and cell shells, that results in the increase of the juice yield.

The technology is based on higher permeability of cell membranes under the influence of an electric current. There happens to be a partial softening and breaking of the cells of the peel, thus making easier its diffusion in the surrounding liquid medium.

Fig. 1 Fig.1 Technological line for processing fruits using electroplasmolysis:
1 - tipper, 2 - input hopper, 3 - washing machine, 4 – inspection
conveyor, 5 - inclined conveyor, 6 – crusher, 7 - pulp hopper, 8
- pump, 9 – electroplasmoliyator, 10 - flow, 11 - press.

Innovative Aspect and Main Advantages

Innovative aspect is expressed in the type and form of the electrical signals, as well as in the construction of the electroplasmoliyator.
The main advantages are:

  • Increased juice yield from vegetables, fruits and berries by 2 - 10%, depending on the type of raw materials
  • Accelerated process of pressing apple pomaceby 20%
  • Increased evaporation rate in the production of concentrate tomato products - by 15%
  • Increased drying rate of pressed apple pomace - by 15-18%
  • Increased exit of cod-liver oil from cod breeds of fish by 8-14 %
  • Decreased content of cod-liver oil in fish flour from a jack mackerel up to 25 %, which increases the flour shelf-life.
