A grass dryer is a machine specially used for drying grass. The main function of the grass dryer is to dry fresh grass in a short time through heating, air circulation and humidity control, so that it can reach a suitable storage state. This process can not only effectively reduce the moisture content of the grass, but also extend its shelf life and service life while maintaining its nutrients.

The working principle of the grass dryer equipment mainly includes the following steps:

1. Heating system: Heat the air to the required temperature by burning fuel (such as coal, biomass) or electric heating.

2. Ventilation system: Send the heated air into the drying chamber to make the air convect and transfer the heat to the grass.

3. Conveying system: Place the grass in the drying chamber and heat it evenly through the conveying system. Usually, the grass is in direct contact with the hot air in the drying cylinder and moves forward in a spiral curve.

4. Control system: Automatically control and monitor the operation of the entire equipment, including the adjustment of parameters such as temperature, humidity, speed, etc., to ensure the best drying effect.

The forage dryer is mainly composed of a hot air furnace, a dryer, a conveyor, a grass cutter, a separator, a baler, a fan, a speed regulating motor, an operating cabinet, etc. These parts work together to achieve the drying of forage. The forage dryer is an efficient, energy-saving and environmentally friendly agricultural machinery and equipment, which is of great significance to improving the quality and utilization rate of forage.
