Alfalfa Rotary Dryer Introduction

The 3 pass rotary drum dryer is usually used for drying the alfalfa grass. The alfalfa dryer can dry the fresh alfalfa with water content of 60-70% to less than 12%, while maintaining the nutrients in the fresh grass, and improving the deep processing of forage. The whole drying process is pollution-free to the forage, which ensures the quality and taste of the forage, improves the storage and utilization rate of alfalfa, and facilitates transportation and feeding.

Alfalfa Rotary Dryer Working Principle

The alfalfa is sent into the drum by the conveyor for downstream drying. It is continuously lifted and scattered under the action of inner lifting board and moves in a spiral way to realize the heat exchange between the grass and hot air. The dried grass moves quickly to discharge from the drum under the action of wind. The wet grass that does not achieve the drying effect cannot move quickly because of its own weight. It will be fully dried in the drum until meeting the moisture requirements for the materials. Then it is discharged by the screw conveyor.

Alfalfa Rotary Dryer Advantages

1.Compared with the single-drum dryer, the length of the machine is shortened by 50%, reducing the building area and saving about 40% project investment.

2. The hot air stove can be equipped with boiling furnace, spray coal stove, hand-fired stove, biomass fuel hot air stove, also used for fuel, gas stove, can bake a block of less than 20mm, granular material, powder, slurry-like materials.

3.The equipment has large processing capacity, strong anti-overload capability, low energy consumption, and can directly reduce the drying cost;

4. The use of co-current, counter-current, mixed flow and other drying technology, greatly improving the thermal efficiency.

5. It can be combined with subsequent processes such as crushing, mixing, pelletizing and packaging to improve the deep processing of forage
