It is the period of fermentation and the waiting time of the product in the fermentation room in the production of quality bread. Thanks to the thermostat and hygrostat in the device, the room temperature and humidity are automatically controlled at the desired level. This unit has a special steam generation system, and the steam and temperature can be adjusted electronically. Also, when only heat or steam is required, the two can be used together with the automatic water discharge system, ensuring the durability and longevity of the air conditioner. Thanks to the fan on the top, the air sucked in from the environment is mixed with the heat and humidity produced by the device and blown into the yeast chamber. The device is completely made of stainless steel and it is very easy to use and install. The control panel of the device is kept separate from the device.
