Zhengzhou Hadof Debuts Intelligent Jam Production Line for Modern Food Processing

February 23, 2025 – Zhengzhou, Henan Province — Zhengzhou Hadof Food Machinery Co., Ltd. has officially launched its new automatic jam production line, offering a complete solution for fruit-based product manufacturers seeking greater efficiency, hygiene, and consistency in food processing. Designed for scalability and versatility, the new line supports the production of a wide range of jams, preserves, and fruit-based fillings.

The system integrates all core stages of jam production—fruit washing, sorting, pulping, concentrating, mixing, sterilizing, and filling—into a seamless and continuous process. With the ability to process up to 2,000 kilograms of raw fruit per hour, the line is optimized for high-volume output while preserving the flavor, color, and nutritional integrity of fresh fruit.

Engineered with modern food safety and automation standards in mind, the production line features high-precision temperature and mixing controls to ensure consistent cooking and texture in each batch. The use of vacuum concentration technology allows for lower-temperature processing, which helps retain natural fruit aromas and reduces energy consumption.

A centralized PLC control system provides real-time data on flow rates, temperatures, mixing speeds, and filling accuracy. This intelligent monitoring enables quick adjustments during production and ensures stable product quality across batches. The control interface supports recipe management and data logging for traceability and compliance with food safety regulations.

The jam line is constructed with food-grade stainless steel and sanitary design principles, including CIP (Clean-in-Place) capabilities, reducing manual cleaning time and risk of contamination. From berry jams to tropical fruit blends, the system can be easily adapted for different product formulations and viscosities, making it suitable for both domestic brands and export-oriented manufacturers.

Early adopters in the food processing sector have reported improvements in production speed, reduced waste, and more consistent product quality. The system is especially beneficial for manufacturers handling seasonal fruits, allowing them to maximize output during harvest periods.

Zhengzhou Hadof aims to promote the jam production line across China and in key global markets where demand for fruit preserves and health-conscious spreads is growing. The company is also developing optional add-ons, such as inline sugar dissolving systems, automated jar labeling, and intelligent packaging modules to further enhance production capabilities.

With this latest innovation, Zhengzhou Hadof continues its commitment to delivering integrated, high-performance solutions for the modern food processing industry. As consumer preferences evolve and food safety requirements increase, automated lines like this are shaping the future of fruit product manufacturing.
