Frequently Asked Questions
What heat sources are available for HSYL industrial drying machines?
We offer flexible heating options to suit your facility's infrastructure. Most of our models can be configured for electricity, natural gas, steam, or biomass energy. For high-capacity needs, we recommend steam or gas for better cost-efficiency, while electricity is ideal for precise control in smaller to medium batches.
How do I determine the correct drying time and temperature for my product?
Drying parameters depend on the water content, slice thickness, and sugar content of your raw material. HSYL machines come with a smart control panel that allows you to set precise temperatures (typically 30°C to 120°C) and timers. We can provide standard drying charts for common items like fruits, vegetables, jerky, and herbs to help you get started.
Are the drying trays and contact parts food-grade certified?
Yes, absolutely. All parts that come into direct contact with food, including trays, trolleys, and the inner chamber, are manufactured from high-quality SUS304 stainless steel. This ensures compliance with international food safety standards (HACCP/FDA), corrosion resistance, and easy cleaning.
What is the air circulation system, and why is it important?
HSYL dryers utilize a hot air circulation system with high-efficiency axial flow fans. This ensures that hot air passes evenly through every tray, eliminating "dead zones." Uniform airflow is critical to ensuring consistent moisture reduction across all products in the batch, preventing spoilage or uneven textures.
Can I dry different types of food in the same machine?
Yes, our machines are versatile. You can dry fruits, vegetables, meats (jerky), seafood, herbs, and even pet treats in the same unit. However, we recommend cleaning the machine thoroughly between batches of strong-smelling items (like seafood) to prevent flavor cross-contamination.
How are the machines shipped, and is installation difficult?
Smaller models are shipped fully assembled and only require an electrical connection. Large-scale industrial drying ovens may be shipped in modules to save on freight costs. We provide detailed video tutorials and wiring diagrams for assembly. For complex production lines, we can arrange for remote guidance or on-site engineer support.
What maintenance is required for the drying machine?
Maintenance is minimal but important. You should regularly clean the air intake filters to ensure proper airflow, wipe down the interior to prevent bacterial growth, and check the door seals for air tightness. We also recommend inspecting the fan motors and heating elements annually.
Do you offer customization for tray sizes or trolley limits?
Yes, as a manufacturer, HSYL provides full customization. We can adjust the number of trolleys, tray dimensions, and shelf spacing based on your specific production capacity and the size of your raw materials.
How energy-efficient are HSYL drying machines?
Our machines are designed with a double-layer insulation structure using high-density rock wool to minimize heat loss. coupled with our hot air recycling system (which reuses a portion of the heated air), this significantly reduces energy consumption compared to standard single-layer dryers.
What is the warranty period and spare parts availability?
We provide a 12-month warranty on core components (motor, heating element, controller). After the warranty period, HSYL guarantees the lifetime availability of spare parts at cost price to ensure your production line never experiences prolonged downtime.
