Microwave Proofing System


System layout

What is Microwave Proofing System ?

Divided and rounded dough pieces are irradiated by microwave to rise dough temperature about 5°C, which leads to promotion of relaxation of dough structure, expansion of gas in the dough, and acceleration/shortening of proofing time by helping fermentation of yeast.

Proofing time cuts down to half of conventional proofing time

  • Graph 1 shows the comparison of conventional proofing and microwave irradiation treatment for dough specific gravity after dividing and rounding dough.
    Specific gravity after 15 minutes conventional proofing is equivalent to 7.5 minutes microwave irradiation treatment.
  • Graph 2 shows the comparison of pressure value required to the rollers when moulding the dough after dividing and rounding.
    As same as specific gravity value, pressure value after 15 minutes conventional proofing is equivalent to 7.5 minutes microwave irradiation treatment.
As result of these experiments,
microwave irradiation treatment can be cut down to half of conventional proofing time.
The quality such as taste, smell of bread make little difference from conventional Proofing.
