Zhengzhou Hadof Launches High-Efficiency Industrial Drying Oven for Food and Herbal Processing

April  01, 2025 – Zhengzhou, Henan Province — Zhengzhou Hadof Food Machinery Co., Ltd. has announced the official release of its new-generation industrial drying oven, engineered to meet the needs of the modern food, agricultural, and pharmaceutical processing sectors. With a focus on energy efficiency, uniform heating, and customizable capacity, the oven is designed to optimize the drying process for a wide range of products—from dehydrated fruits and vegetables to Chinese medicinal herbs and tea leaves.

This advanced hot air circulation oven uses a combination of axial flow fans, automatic temperature control systems, and thermal insulation structures to ensure stable and consistent drying at controlled temperatures. Designed to handle up to several hundred kilograms per batch, it offers high thermal efficiency while maintaining the integrity, color, and active ingredients of the materials being dried.

“Our new drying oven integrates smart control and air circulation optimization to help manufacturers reduce drying time and energy consumption while improving product quality,” stated a company representative. “It’s a practical, scalable solution for a variety of industries.”

The oven’s multi-layer tray design allows for high-volume batch drying, while the internal airflow system ensures that hot air is evenly distributed across all layers. This eliminates hotspots and uneven drying—common problems in traditional drying equipment. The temperature range can be precisely controlled between 40°C and 160°C, suitable for heat-sensitive products as well as items requiring higher thermal treatment.

A key feature is the digital PLC control system, which enables real-time monitoring and programmable drying cycles. Operators can set specific drying durations and temperature curves based on different product types. Once the process is complete, automatic alarms ensure timely operation, reducing the need for manual supervision.

Constructed entirely of food-grade stainless steel, the drying oven meets national and international hygiene standards. It also features double-layer thermal insulation to prevent heat loss and improve energy efficiency. Optional upgrades include humidity control modules, mobile rack systems, and gas or electric heating options depending on user requirements.

Customers from the food and herbal industries have already begun implementing the new oven, reporting faster drying times, lower energy bills, and better product uniformity. The machine is especially well-received among processors of dried fruit, root herbs, seasoning powders, pet food, and ready-to-eat snacks.

With the market for dehydrated and natural health products expanding rapidly, Zhengzhou Hadof’s drying oven positions the company as a reliable supplier of modern drying technology. Plans are underway to develop a continuous conveyor-type drying system and integrate IoT-based data tracking for future product iterations.

As industrial processing moves toward smarter and cleaner operations, the release of this oven reflects Hadof’s commitment to innovation, quality, and sustainability across the food machinery sector.
