The grain dryer is an indispensable equipment in grain storage and processing. It dries the grain by controlling the speed of air flow, ensuring that its moisture content is within a safe range, thereby extending the shelf life of the grain and ensuring its quality. In this drying process, the flow servo valve plays a crucial role, responsible for precisely controlling the air flow entering the dryer to ensure the stability and efficiency of the drying effect.

The flow servo valve in the grain dryer is an automatic control device used for precise control of the air flow. It uses a servo motor as the power source and receives and processes signals from temperature, humidity, and other sensors through the electronic control unit (ECU), thereby achieving precise control of the air flow. The precise control capability of this valve allows the air flow during the drying process to be adjusted according to the drying requirements of the grain, avoiding problems such as poor drying effect or energy waste due to excessive or insufficient flow.

The working principle of the flow servo valve is to adjust the size of the air flow by changing the position of the valve core. When it is necessary to increase the air flow, the servo motor drives the valve core to move towards the air flow inlet, increasing the cross-sectional area of the air flow channel, allowing more air to pass through; conversely, when it is necessary to reduce the air flow, the valve core moves towards the air flow outlet, reducing the cross-sectional area of the air flow channel, and reducing the amount of air passing through. This precise control not only ensures the drying effect of the grain but also effectively reduces energy consumption, improving the working efficiency of the dryer.

　　In practical applications, the accuracy of the flow servo valve directly affects the working efficiency and drying effect of the dryer. Therefore, selecting a flow servo valve with stable performance and high accuracy is crucial for the grain dryer. With the development of scienceand technology, the performance of the flow servo valve is also continuously improving, such as adopting more advanced electronic control technology and more durable materials, to meet the needs of different application scenarios.

In general, the flow servo valve of the grain dryer is a key technology to improve drying efficiency and ensure the drying effect. By precisely controlling the air flow, it can ensure the stability and efficiency of the grain drying process, thereby guaranteeing the quality of the grain. With the advancement of science and technology, the performance of the flow servo valve will continue to improve, providing possibilities for further optimization of the grain dryer.
