Frequently Asked Questions

Everything you need to know about our standalone drying & roasting systems

For standard electric multi-layer ovens like the ZHKX-VD-500 and ZHKX-VD-300, our factory delivery lead-time is 15 to 20 working days. For high-capacity multi-fuel systems, such as the ZHKX-RF-400 gas oven or customized steam ovens, the timeline is approximately 30 to 45 working days to ensure comprehensive thermal cycle testing.
Yes, absolutely. All Zhuoheng ovens feature modular mechanical linkages, standardized inlet conveyors, and independent VFD speed-adjusted control panels. This allows seamless speed synchronization with any existing third-party extruders or packaging systems with minimal plant downtime.
It depends on your local energy costs. Electric heating (ZHKX-VD series) offers zero emissions and precise zone temperature profiling but is best where electricity is cheap. Gas/diesel heating (ZHKX-RF & ZHKX-VY) provides fast temperature rise and is highly economical in most zones. Steam heating (ZHKX-VQ) reduces electrical consumption down to 11.5kW by utilizing your pre-existing factory steam boiler.
Our thermal engineering utilizes convective recirculating fans to distribute heat equally throughout the multi-tier chambers. This eliminates localized hot spots and prevents moisture condensation. Combined with precision PID controllers that monitor temperature variables to keep fluctuations within ±1°C, products dry uniformly from core to crust.
Yes. Every multi-layer oven is equipped with sliding stainless steel bottom drawers beneath the mesh conveyors. Falling crumbs and fines are caught directly in these trays. Operators can easily pull them out to sweep away residues, completely preventing product build-up, mold growth, or potential fire hazards under heat tubes.
Our mesh belts are made of food-grade SUS304 stainless steel, and the double-pitch roller chains are heat-treated alloy steel. Under normal continuous 24/7 operating conditions with proper routine lubrication, they have a wear life of 5 to 8 years. As an OEM source factory, we maintain a complete wear-parts inventory globally for immediate shipment.
