Wineries choose steam boilers mainly because steam has advantages such as precise temperature control, uniform heating, easy adjustment, cleanliness and hygiene, and safety and reliability in the wine production process. The following are the specific reasons:
1. Fermentation temperature control
Wine fermentation requires strict temperature control (red wine is generally 25-30°C, and white wine is 15-20°C). Steam passing through the heat exchanger can stably and precisely regulate the temperature of the fermentation tank, avoiding local overheating or temperature fluctuations.
2. Sterilization and hygiene requirements
Steam is a natural bactericide and can be used to sterilize equipment, pipelines and fermentation tanks, ensuring that wine is not contaminated by miscellaneous bacteria.
3. Uniform heating
Steam heating is carried out through a heat exchanger and does not directly contact the wine body, avoiding changes in wine quality caused by local high temperatures. The heating process is more gentle and uniform.
Easy to adjust and automate
The steam pressure and flow rate can be precisely controlled, facilitating linkage with an automated system to achieve automatic adjustment of fermentation temperature and sterilization temperature.
4. Safe and reliable
The steam boiler technology is mature, operates stably, and the steam itself does not burn or explode, making it safe to use.
5. High energy efficiency
Steam boilers have high thermal efficiency and can quickly meet the heating demands during the brewing process, reducing energy consumption.
6. Versatility
Steam is not only used for temperature control and sterilization during fermentation, but also for multiple processes such as distillation of grape skins and residue, hot water supply, and heating in workshops.
