Steam Runs Through the Brewing Process: ZOZEN Boiler Supports the Baijiu Industry

Baijiu production is a continuous process. From grain steaming and fermentation to distillation, sterilization, and fermented-grain residue handling, many stages require a stable steam supply. As baijiu producers expand their operations, boiler systems need to provide sufficient steam while also adapting to different fuel conditions, changing loads, and environmental management requirements.

In recent years, ZOZEN Boiler has developed steam boiler and auxiliary system solutions for baijiu producers in Sichuan, Guizhou, and other production regions. These solutions are designed around the characteristics of the baijiu industry, helping plants improve energy allocation and support stable production.

Adapting to Local Conditions and Fuel Availability
Sichuan is an important baijiu-producing region in China, with relatively abundant agricultural and forestry residues as well as biomass fuel resources. Sichuan Langjiu Co., Ltd. requires a continuous and stable steam supply for brewing, distillation, fermented-grain residue handling, and auxiliary production processes. Based on the project’s fuel conditions and steam demand, the Langjiu project selected a ZOZEN DZW reciprocating-grate biomass-fired steam boiler with a rated evaporation capacity of 30 tons per hour.

ZOZEN Reciprocating-Grate Biomass-Fired Steam Boiler for the Baijiu Industry

The DZW biomass-fired steam boiler can use various fuels, including biomass pellets, straw, wood blocks, palm shells, rice husks, corn cobs, and waste wood. It adopts a reciprocating-grate combustion system, allowing the fuel configuration to be adjusted according to actual project conditions. This provides a suitable steam source option for breweries and distilleries with access to biomass fuels.

For the Langjiu project, ZOZEN Boiler supplied the boiler body and auxiliary systems, and provided on-site commissioning services. The system configuration was developed with consideration of the plant layout and operating requirements, enabling the boiler system to match the production process.

Precise Steam Control for Sauce-Aroma Baijiu Production
During the production of sauce-aroma baijiu in Guizhou, steam pressure and temperature require careful adjustment. Processes such as grain steaming, distillation, fermentation support, and sterilization place specific demands on steam supply continuity and control.

ZOZEN SZS Gas-Fired Steam Boilers for Distilleries

Jiangjiu Liquor Co., Ltd. has been engaged in the production of sauce-aroma baijiu since its establishment in 1996. To support production expansion and energy management, the company selected a ZOZEN SZS gas-fired steam boiler with a capacity of 18 tons per hour.

The SZS gas-fired steam boiler adopts a membrane water-wall structure and is equipped with a burner and automatic control system. It can adjust operation according to steam pressure, boiler water level, and steam load. According to the project configuration data, the boiler’s thermal efficiency can reach over 100%. When combined with low-NOx combustion technology, it can also help control nitrogen oxide emissions and meet the requirements of energy management and environmental control in distilleries.

Circulating Fluidized Bed Boiler Project in Mongolia
In Mongolia, a company producing beverages, beer, and vodka selected a ZOZEN 8 tons per hour SHX circulating fluidized bed steam boiler. The boiler supplies steam for raw material processing, brewing, sterilization, and cleaning. Considering the local climate, fuel conditions, and continuous production requirements, ZOZEN Boiler carried out technical communication regarding equipment configuration, site conditions, and installation coordination to provide a steam system solution adapted to the project.

For baijiu producers with changing steam loads, an automatic control system can reduce manual operations and help operators monitor boiler conditions. Multiple safety protection devices provide interlock control for parameters including water level, pressure, and combustion, supporting the continuous operation of the boiler system.

From Boiler Manufacturing to System Services
A boiler project for the baijiu industry involves multiple components, including the boiler body, combustion system, feedwater system, flue gas treatment, control system, and on-site installation. Boiler selection should take into account the plant’s production capacity, steam pressure, fuel supply, environmental requirements, and available space, rather than relying on a single parameter.

ZOZEN Boiler can provide boiler bodies, auxiliary systems, solution design, installation and commissioning, and technical training according to actual customer requirements. After the equipment is put into operation, the company also provides maintenance support. Whether it is a biomass-fired steam boiler project in Sichuan or a gas-fired steam boiler project in Guizhou, the solution is developed around the customer’s brewing process and operating conditions.

From the brewing workshop to the boiler room, a stable steam supply is an important foundation for orderly baijiu production. ZOZEN Boiler will continue to provide gas-fired steam boilers, biomass-fired steam boilers, and auxiliary system solutions based on the fuel conditions, production processes, and environmental requirements of baijiu producers, supporting energy management and production operations in the baijiu industry.
