Steam Boiler in Food Industry: Reliable Heat Source Empowering Quality Production with ZOZEN Boiler

In the modern food manufacturing sector, energy reliability and efficiency are essential for maintaining consistent product quality and production stability. Among various types of industrial heating equipment, the steam boiler in food industry plays an indispensable role. It provides the stable and high-temperature steam required for sterilization, drying, cooking, concentration, and cleaning—processes fundamental to ensuring food safety, flavor, and productivity.

The steam boiler in food industry must operate under demanding conditions where precision, cleanliness, and continuous supply are paramount. Any fluctuation in steam pressure or temperature could affect the texture, taste, or shelf life of the final product. Therefore, food manufacturers require boilers that not only deliver high efficiency and stable performance but also comply with strict hygiene and environmental standards. From meat processing and beverage bottling to dairy pasteurization and sauce production, steam boilers are at the heart of thermal energy systems that define industrial competitiveness.

Advanced ZOZEN Steam Boilers Tailored for Food Processing

The SZS series is a water tube boiler that adopts a double-drum, longitudinal D-type structure. It features a full membrane wall design to ensure complete sealing and excellent thermal insulation. This structure allows the boiler to operate under high pressure while minimizing heat loss and improving efficiency.Fuel—natural gas, light oil, or other clean energy sources—is atomized through an advanced burner, producing a uniform and efficient flame. The flue gas generated passes through a radiant furnace and then a convection heating surface, achieving a thermal efficiency up to 98% when equipped with economizers and condensers.The furnace of the SZS boiler is spacious, promoting full fuel combustion and low NOx emissions that meet international environmental standards. It also incorporates an automatic PLC control system, enabling precise adjustment of combustion parameters, steam pressure, and water levels. For food manufacturers, this means consistent steam quality and stable supply during peak production periods, ensuring product integrity and reducing downtime.

The SZL series is one of ZOZEN’s signature biomass boiler models, known for its horizontal double-drum, chain grate, water tube design. It can utilize a wide range of biomass boiler fuels, such as wood chips, sawdust, rice husks, and palm shells, offering flexibility for regions rich in agricultural residues.Its furnace is surrounded by water-cooled walls connected to upper and lower drums, forming a strong, closed combustion chamber that absorbs radiant heat efficiently. The high-temperature flue gas then travels through the convection tube bundle and economizer before being discharged. This configuration ensures efficient heat utilization and steady steam generation.The chain grate and air distribution system can be customized according to fuel characteristics, ensuring complete combustion, reduced carbon residue, and lower operational costs. With its ability to achieve over 86% thermal efficiency, the SZL boiler is an ideal choice for food processors seeking to balance performance, sustainability, and cost-effectiveness.

The DZL series boiler is a single-drum, chain grate steam boiler suitable for various industrial applications. It adopts a three-pass water-fire tube hybrid structure, featuring a large furnace design that improves combustion efficiency and reduces smoke emission. The furnace arch is optimized to support mixed fuel combustion and enhance heat absorption.This boiler’s advantages lie in its simple installation, reliable performance, and ease of operation. The threaded smoke tubes and corrugated furnace enhance heat transfer, while the economizer further reduces exhaust gas temperature, improving overall efficiency. For food plants located in regions where biomass or gas fuels are less available, the DZL boiler provides a cost-effective and dependable steam source.

Each of these boilers is built with ZOZEN’s commitment to durability and intelligent control, ensuring they meet the demanding thermal needs of the steam boiler in food industry sector.

Tomato Paste Manufacturer Achieves Continuous Production with Steam Boiler in Food Industry

A well-known tomato processing enterprise recently faced a common challenge among tomato paste manufacturers — how to maintain continuous, high-quality production during a tight 45- to 55-day processing season. The company needed a partner with deep understanding of food manufacturing, especially in steam-intensive processes, and sought equipment that could guarantee 24-hour operation with stable steam supply and safety assurance.

The company selected ZOZEN Boiler as its technology partner after a comprehensive evaluation of multiple suppliers. ZOZEN proposed a complete steam solution featuring a 35-ton SZS series gas-fired water tube boiler, designed to deliver consistent and high-pressure steam for the entire production cycle.

During tomato paste concentration, evaporation, and sterilization, the production load fluctuates rapidly, placing heavy demands on steam output. The SZS boiler’s large furnace volume and full-membrane wall design ensure strong adaptability to such variations. Its advanced burner system and automated control maintain steady steam pressure and temperature even during peak operation, which is critical for maintaining product texture and quality.

Additionally, the boiler is equipped with an economizer and condenser to recover waste heat, significantly improving energy efficiency and lowering fuel costs. The intelligent PLC control system simplifies monitoring and enhances operational safety, minimizing manual intervention.

Beyond product performance, ZOZEN’s comprehensive after-sales service was a decisive factor for the client. The company’s technical team provided full support throughout installation, commissioning, and trial operation. During production, ZOZEN’s service engineers remained on standby, ensuring that any technical issue could be addressed promptly, thereby preventing production interruptions. This responsive service system allowed the tomato paste manufacturer to meet its seasonal production goals smoothly and efficiently.
