Fermentation and distillation are the two main uses of winery boilers. Fermentation is the fermentation of koji, grain and other mixtures to produce alcohol; distillation is the use of a still, condenser, etc. to extract the alcohol in the grain to produce puree liquor. Winery fermentation, distillation, etc. require a relatively large amount of steam. If coupled with heating and bathing heat, the amount of steam is greater. Therefore, wineries use coal-fired steam boilers as fermentation and distillation boilers. With the increasing awareness of environmental protection in China, quite a few local governments have restricted the use of small coal-fired boilers. Gas boilers, biomass boilers and other equipment have emerged as they emerged. Their low-cost operation, no nitrogen oxides and sulfides contaminated the winery waiting for the love of enterprises.
