Types of Boilers Used in the Food Industry

1. Common Types of Steam Boilers in the Food Industry

In the food industry, the efficiency and reliability of steam boilers are critical for numerous applications, including heating, sterilization, and cleaning. The types of boilers used in the food industry are designed to meet specific needs, ensuring that processes are both effective and compliant with health standards. Here are the most common types of steam boilers utilized in the food sector:

Biomass Boilers: Increasingly popular for their environmental benefits, biomass boilers utilize organic materials as fuel, providing a sustainable option for steam generation.

Gas and Oil Boilers: These are commonly used in the food industry due to their efficiency and availability. They can be tailored for various applications depending on the fuel type.

Coal Boilers: As a traditional boiler type, coal boilers feature low fuel cost and strong adaptability, making them suitable for food industrial users with large demand for steam.

Each of these types of boilers used in the food industry serves specific operational roles, making them essential for companies aiming to enhance productivity and meet regulatory requirements.

2. ZOZEN’s Suitable Boiler Models for the Food Industry

ZOZEN Boiler, a prominent player in the boiler manufacturing industry, provides high-quality boiler solutions tailored for the food sector. Let’s explore three specific ZOZEN boiler models that are especially suited for food industry applications: the WNS Oil and Gas Steam Boiler, the DZL Biomass Boiler, and the SZL Coal-Fired Boiler.

WNS Oil and Gas Steam Boiler

ZOZEN WNS series is a fire tube boiler designed for efficient, high-performance steam generation.

High Efficiency: ZOZEN’s WNS boiler can achieve thermal efficiencies of up to 98% with a condenser, significantly reducing fuel consumption and operating costs.
Compact Design: Its compact structure allows for easy installation, making it suitable for smaller food production facilities.
Low Emissions: Equipped with advanced burners, the WNS boiler minimizes NOx emissions, aligning with environmental regulations.
The WNS oil and gas steam boiler’s features make it ideal for food processing operations that require both efficiency and environmental compliance.

Recently, ZOZEN Boiler successfully supplied two WNS series gas-fired steam boilers to a large meat processing plant in Venezuela—one 5 tph steam boiler and one 10 tph steam boiler. These boilers are utilized on two separate production lines within the plant, ensuring a stable and efficient supply of steam throughout the production process.

The production and processing of meat products involve multiple stages such as raw material handling, sterilization, steaming, and drying. Each of these stages requires a consistent and reliable steam supply. Stable steam not only enhances the quality of the processed products but also ensures food hygiene and safety. As a result, the performance of the boiler equipment directly impacts the factory’s production efficiency and product quality.

The WNS series gas-fired steam boilers feature a three-pass fire-tube structure with a corrugated furnace and high-efficiency heat transfer tubes. This design significantly improves heat exchange efficiency, achieving a thermal efficiency exceeding 98%. For the meat processing plant, this translates into substantial fuel savings, lower production costs, and reduced carbon emissions—delivering both economic and environmental benefits for the customer.

Both boilers provided by ZOZEN have been certified by ASME (American Society of Mechanical Engineers), which underscores their superior manufacturing quality and operational safety. ASME certification is a globally recognized standard in the boiler equipment industry, and equipment that meets this certification is better equipped to satisfy the stringent requirements of international markets.

DZL Biomass Boiler

The DZL series represents ZOZEN’s commitment to sustainable and environmentally-friendly solutions.

Renewable Energy Source: Designed to use biomass as fuel, the DZL boiler minimizes reliance on fossil fuels, helping companies reduce their carbon footprint.
Efficient Heat Exchange: Its efficient design allows for maximum heat transfer, ensuring optimal steam generation. Thermal efficiency can be over 83%.
Automatic Feeding System: The DZL boiler features an automated feeding system, enhancing convenience and operational efficiency.
This biomass boiler is perfect for food manufacturers focused on sustainability while maintaining high operational efficiency.

Recently, ZOZEN Boiler successfully exported two sets of steam boiler equipment to Spain. This project provided two efficient and environmentally friendly steam boilers for a local agricultural and sideline product processing plant in Spain, meeting their production needs while achieving efficient energy utilization and sustainable environmental development. As the customer’s production scale continues to expand, the demand for energy is also increasing.

The customer requires a steam boiler solution that can meet production capacity requirements and comply with the strict European environmental protection standards.

Main Equipment Introduction:

4 tph Biomass Steam Boiler:

Fuel Selection: Oat shells are chosen as fuel due to their renewability and low pollution characteristics, in line with Europe’s promotion policy for renewable energy.

Technical Features: The boiler is designed with high thermal efficiency, and its emissions meet European environmental standards, ensuring a clean and efficient production process.

1.5 tph Diesel Steam Boiler:

Backup Function: As a backup boiler, it ensures that production is not affected during the maintenance of the main boiler or in case of failure.

System Customized Solutions:

Lock Hopper: The customized lock hopper can achieve uniform feeding, effectively preventing hopper backfire, ensuring the stable operation of the boiler.

Fans and Pumps: These auxiliary equipment work in conjunction with the main boiler, improving the efficiency and reliability of the entire system.

Speed Control Box and Frequency Conversion Technology: The application of the speed control box and frequency conversion technology allows the boiler to adjust its operating state according to actual needs, achieving energy saving and consumption reduction.

SZL Coal-Fired Boiler

The SZL series is a water tube boiler designed for industries requiring large steam quantities.

High Capacity: The SZL boiler can cater to high steam demand in large-scale food production processes like canneries. Thermal efficiency can be over 81%.
Durable Construction: Built with high-strength materials, the SZL boiler provides durability and long operational life.
Cost-Effective: Using coal as a fuel source can be economically beneficial for certain regions where coal is readily available.
The SZL coal-fired boiler is advantageous for food production facilities that predominantly operate in areas with accessible coal resources.

PT.Musim Mas Group is a world leading palm oil manufacturer, its products are used in food, chemical, power industries etc.. In refinery plant, oils decoloring, deodorization, each product’s heating and evaporating, there are many processes that need steam; food industry has high requirements for sanitation, steam is used a lot for disinfection and sterilization. Food plants are usually running 24 hours, once stops, it will need a lot of disinfection and sterilization.

After visiting and comparing, PT.Musim Mas Group chose ZOZEN SZL type coal-fired steam boiler. It has upper part and lower part for transportation and upper part is body heating surface; lower part is combustion room. This boiler is easy to install on site, costs less installation time, and easy to operate. In Indonesia, there are several palm oil plants using ZOZEN SZL series boilers.
