Advantages
Why the 5L-80 is one of the stronger confirmed models in the 5L family.
Higher-capacity matched solution
The 5L-80 is documented as the furnace matched with Tongtai’s 55-ton newly developed batch grain dryer.
Stable indirect heating
It is positioned for indirect hot-air heating, stable pellet combustion, and reliable hot-air delivery for larger batch drying applications.
Practical medium-scale range
The current source set presents it as a medium-scale solution that can support larger batch dryers without moving to a much larger furnace class.
Key Features
Core engineering and control features documented in the current source set.
Full-Automatic Piston Feeding
Automatic piston feeding supports consistent pellet supply and reduced manual intervention.
Automatic Ash Cleaning
Automatic cleaning with manual assistance helps improve daily operating convenience.
Intelligent Constant-Temperature Control
The control logic is designed to maintain stable hot-air output under changing conditions.
Indirect Hot-Air Heating
Indirect hot-air heating helps keep the furnace suitable for grain drying support applications.
Safety Protection Package
The source set documents over-temperature, leakage, flameout, and fault-alarm protections.
Medium-Scale Dryer Matching
The model is described as suitable for matching with two medium dryers in standard scenarios.
Applications
Typical project scenarios where the 5L-80 is a good fit.
Medium-Scale Grain Drying
Suitable for medium-scale grain drying and hot-air applications.
Batch Grain Dryers
A strong matched heat source for Tongtai’s larger batch dryer configurations.
Drying Rooms
Can support drying-room and related hot-air demand in indirect-heating setups.
Related Hot-Air Projects
