FAQ

Q1: How long is the typical drying cycle of this tunnel oven?

A:The drying time depends on the initial moisture content of the materials and the required final moisture level. Generally, the residence time can be adjusted by controlling the conveyor speed, ranging from approximately 15 minutes to 2 hours.

Q2: Are there any restrictions on the shape of materials suitable for drying?

A:The equipment is mainly suitable for granular, flake, strip-shaped, and block-shaped materials. Powder materials require pre-granulation or the use of specially designed high-density mesh belts to prevent material leakage.

Q3: How does the equipment protect biological active ingredients during drying?

A:The system supports low-temperature and high-air-volume drying modes (40℃-60℃) with precise temperature control, effectively preserving the active ingredients and nutritional properties of medicinal herbs and biological products.

Q4: How is the energy consumption performance of this equipment?

A:The equipment adopts a high-density rock wool insulation layer combined with a hot air circulation recovery system. Compared with traditional box-type dryers and standard tunnel ovens, it can reduce energy consumption by more than 30%.

Q5: How can conveyor belt deviation be corrected during operation?

A:The equipment is equipped with automatic or manual belt tension adjustment and correction devices. If belt deviation occurs, the operator can quickly restore the belt to the center position by adjusting the correction bolts on both ends of the rollers.
