Zongzi steaming and boiling equipment The safety valve shall be used in accordance with the specified configuration and must not be adjusted independently. During operation, the zongzi steaming equipment requires regular monitoring of the thermal oil temperature. The thermal oil temperature should generally not exceed 150°C (controlled by the electrical control cabinet). When operating above 150°C, promptly adjust the temperature, closely observe changes in oil temperature and pressure, and implement additional safety measures.

　　After heating the material to the required temperature, the safety valve of the zongzi steaming and cooking equipment must be the designated model provided by our company; self‑adjustment is strictly prohibited. During operation, closely monitor changes in the thermal oil temperature. The thermal oil should generally not exceed 150°C (controlled by the electrical control cabinet). If the temperature rises above 150°C, promptly adjust it, keep a close eye on fluctuations in oil temperature and pressure, and implement additional safety measures. Drain the material from the bottom of the pot. Before each shift, lubricate all moving parts and inspect the electric heating rods for damage. For the surface of the agitator‑type sandwich pot, use refined vegetable oil; elsewhere, apply 30–40-grade machine oil. After using the zongzi steaming and cooking equipment, first disconnect the power supply, then immediately flush the pot with tap water to protect the electric heating rods and extend their service life. When adding thermal oil, it is recommended to use oil rated for 320°C, as this allows for rapid temperature rise and improved operational efficiency. Prior to refilling, seal the drain port; fill the oil to a level 4–5 cm below the overflow opening. Before heating, close one side of the overflow port with a valve and connect the other side to a pipeline for heating. During heating, excess thermal oil may flow into the collection tank. After 4–5 cycles, the overflow port can be sealed with a valve.

　　The zongzi steaming and cooking equipment uses natural gas or liquefied petroleum gas as its heat source. Developed by our company based on the principles of simplicity and practicality, this equipment is designed for small and medium-sized food processing plants. Our tilting‑type gas‑powered zongzi steamer is constructed entirely from stainless steel, with a capacity ranging from 300 to 1,000 liters—options available—and offers fast, hygienic, and convenient operation. The high‑pressure zongzi cooker boasts advantages such as complete combustion, zero smoke and dust, minimal carbon buildup, and no environmental pollution. Flame temperature is freely adjustable, reaching approximately 300°C. With a well‑designed structure, it is easy to operate, highly energy‑efficient, delivers powerful heating, and achieves a thermal efficiency roughly 25% higher than comparable products.

　　The high-pressure zongzi cooker must not be used with liquefied petroleum gas, piped city gas, natural gas, or petroleum. Its gas consumption is approximately 20% lower than that of comparable products. Zongzi steaming and boiling equipment Liquefied petroleum gas or natural gas is used in place of a boiler, making it ideal for facilities with stringent environmental requirements and for small to medium-sized dumpling factories. It is easy to operate, highly safe, and ensures cleanliness and hygiene. Equipped with an energy‑efficient burner and a blower for auxiliary heating, it boosts heating speed while reducing energy consumption. Cooking one batch requires approximately 3–6 kg of gas, significantly lowering production costs.
