Tomato processing is highly seasonal, with an annual production window of only 45 to 55 days. During this limited timeframe, equipment must operate continuously at high load without unexpected shutdowns. Understanding this challenge, the customer set strict standards for reliability, energy efficiency, and operational stability when constructing the new 3,000-ton-per-day tomato processing line. After extensive technical evaluation and supplier comparison, the company ultimately chose the 35 t/h SZS Gas Steam Boiler from ZOZEN Boiler’s SZS series.

ZOZEN 35 t/h SZS Gas Steam Boiler

The 35 t/h SZS Gas Steam Boiler adopts a double-drum, D-type layout, a proven structure widely recognized for its safety and stable operation. Its spacious combustion chamber design allows for sufficient fuel-air mixing, ensuring complete combustion and steady steam output. Equipped with advanced low-NOx burners, the 35 t/h SZS Gas Steam Boiler not only delivers strong thermal power but also helps the enterprise meet environmental requirements. For export-oriented food processing companies, consistent steam pressure and temperature are essential to maintaining uniform product color, texture, and taste.

One of the most distinctive features of this project was the large volume of high-temperature condensate water generated during tomato concentration and sterilization. Instead of allowing this valuable heat resource to go to waste, ZOZEN’s technical team designed a customized energy-saving system tailored to the plant’s operating conditions. By integrating an air preheater and a condensate recovery device into the 35 t/h SZS Gas Steam Boiler system, the project significantly improved overall heat utilization efficiency. The recovered condensate water, still carrying substantial thermal energy, is returned to the system, reducing the need for additional fuel consumption and lowering operating costs.

This optimized configuration enhances the comprehensive performance of the 35 t/h SZS Gas Steam Boiler. The air preheater captures residual heat from flue gases to preheat combustion air, promoting more efficient fuel burning. Meanwhile, the condensate recovery system reduces thermal losses and stabilizes feedwater temperature, contributing to smoother boiler operation. These measures not only improve energy efficiency but also reduce thermal shock within the boiler, extending equipment service life.

During peak processing season, when tomatoes are delivered in large volumes and production lines run around the clock, the 35 t/h SZS Gas Steam Boiler operates at full capacity. Its robust structural design and high automation level allow for stable and continuous steam supply, minimizing manual intervention and reducing operational risks. For a project with such a short yet intensive production cycle, this level of operational reliability is essential. Stable boiler performance ensures uninterrupted concentration and sterilization processes, safeguarding both output and product quality.

Beyond performance, the project also demonstrates how careful system integration can bring long-term economic benefits. By improving heat recovery and optimizing combustion efficiency, the 35 t/h SZS Gas Steam Boiler helps the company control fuel expenses while maintaining high production standards. In an industry where margins are closely tied to seasonal output, energy savings during peak production directly enhance overall profitability.
