Thailand is one of the world's leading agricultural exporters with a particularly developed fruit processing industry. A dried fruit processing factory located in Chanthaburi Province, eastern Thailand ordered a vertical type LPG fired once-through flow steam boiler from
Sitong boiler who primarily produces products such as dried durian, dried mango, and dried longan. With the surge in global demand for healthy snacks in recent years, the factory decided to expand its production scale and replace its aging, low-thermal-efficiency coal-fired boiler to meet stricter environmental regulations and higher product quality requirements .In the production process of this factory, saturated steam is an indispensable energy carrier.For example, in the drying process, stable steam needs to be passed through a heat exchanger to generate hot air for removing moisture from fruit slices. In the sterilization and disinfection process, high-temperature steam is used for on-site cleaning of production line equipment and pipelines. In the sugar soaking or heating shaping process, steam is required to maintain a specific temperature. This dried fruit factory ultimately selected the LSS2-1.0-Y(Q) once-through flow steam boiler fueled by LPG, supplied by
Sitong boiler after multiple rounds of technical comparisons and site visits. This choice was primarily based on the technical advantages for this model.
The LSS2-1.0-Y (Q) LPG fired once-through flow steam boiler from
Sitong boiler adopts a vertical three return structure, which has the characteristics of small footprint and fast start stop. It can perfectly adapt to customers' compact plant layouts. The dried fruit processing production line usually does not operate continuously around the clock, but intermittently produces according to the batch of fresh fruit arrival.This boiler can quickly generate saturated steam within 3-5 minutes after starting the cold furnace. This feature can save factories a significant amount of standby fuel costs every day and achieve a flexible production mode of "on-demand start-up" compared to traditional boilers that require several hours of furnace preparation. For the Thai market where LPG fuel costs are high, thermal efficiency is crucial to the food enterprises. The boiler is designed with a thermal efficiency of up to 98%, thanks to its optimized heat exchange surface layout and lower exhaust gas temperature. It can meet the special needs of Thailand's dried fruit processing industry with its fast start-up, high efficiency, energy saving, and environmentally friendly low emission characteristics. This is not only an equipment update, but also a crucial step for the dried fruit factory to achieve production flexibility, reduce operating costs, and align with international environmental standards.
Sitong boiler will continue to provide reliable energy support for the deep processing industry of agricultural products in Southeast Asia by providing products that comply with international standards such as ISO and CE certification and comprehensive after-sales service.
