If you are struggling with the issue of fermentation temperature not rising, there are two solutions: improving ventilation and introducing a warm air device.

How to Improve Ventilation

Improving ventilation advances fermentation, causing the temperature to rise without heating

In particular, if you fall under the following conditions, improving ventilation is expected to raise the fermentation temperature and stabilize the process:

  • 1.No ventilation equipment
  • 2.Frequent clogging of ventilation
  • 3.Wide pitch of ventilation pipes
  • 4.Creation of air passageways
  • 5.Using blower ventilation, leading to a significant temperature drop in winter

Methods for Introducing a Warm Air Device

Introducing a hot air equipment raises the fermentation temperature artificially

In particularly cold regions such as northern Japan, where the environment can be as low as -20 degrees, the temperature does not easily rise, which weakens the activity of microorganisms. By heating to a certain temperature, it is possible to promote the proliferation of high-temperature microorganisms and increase the fermentation temperature.
