  • The method consists in creating oxygen-free pressure atmosphere (carbon dioxide) and using the effect of quick atmosphere decompression. It is an alternative method to the disinfestation of plant raw materials with the application of poisonous chemical compounds (methyl bromide, phosphine, ethylene oxide and others).
  • Process parameters:
    • pressure: up to 20 bars,
    • time of exposure: 1 ÷ 2 h,
    • decompression speed: 5 bars/min.

Process description:

  • The method consist in creating oxygen-free pressure atmosphere (carbon dioxide) and using the effect of fast atmosphere decompression. It is an alternative method to the disinfestation of plant raw materials with the application of poisonous chemical compounds (methyl bromide, phosphine, ethylene oxide and others).
  • Process parameters:
    • pressure: up to 20 bars,
    • time of exposure: 1 ÷ 2 h,
    • decompression speed: 5 bars/min.

The process can be conducted periodically or continually in two autoclaves operating interchangeably. During decompressing of the first autoclave, the released gas is introduced to the other autoclave to the point of balancing the pressure in both vessels, after which fresh gas is compressed into the second autoclave. The gas is taken from the liquid CO2 vessel and then vaporized. The whole process leads to the reduction in reduced CO2 unit consumption almost by half.Pressure disinfestation of plant raw materials with carbon dioxide
