Rice(paddy) dryer is a kind of equipment specially used for rice (paddy) drying. Its working principle and advantages are of great significance for improving the storage quality of rice(paddy) and reducing storage costs.

Working principle of rice(paddy) dryer

The working principle of rice(paddy) dryer mainly includes the following steps:

1. Heating: The rice(paddy) dryer generates heat energy through a heating device (such as gas, fuel oil, biomass and other heat sources), which is converted into hot air through combustion.

2. Hot air circulation: Hot air is blown into the drying room through the fan to exchange heat with the rice. The moisture on the surface of the rice evaporates at high temperature to form moisture.

3. Humidity control: The dryer is equipped with a humidity control system, which can monitor and adjust the humidity in the drying room in real time. When the humidity reaches the set value, the exhaust system will start to discharge the moisture in the room to maintain a dry environment in the drying room.

4. Rice flow and slow revival: Rice flows from top to bottom in the drying room, and hot air enters from the air inlet horn box and passes through the grain layer and is discharged from the exhaust horn box. The dried hot grain will flow to the slow-souring section, and the temperature and moisture of the inner and outer layers of the grain will tend to balance after the slow-souring section, achieving the effect of uniform precipitation.

5. Cycle detection and packaging: After the rice enters from the feed hopper, it will be tested by equipment such as elevators and moisture detectors. If the moisture content does not meet the standard, it will continue to enter the drying cycle; if it meets the standard, it will enter the grain discharge pipe and be packaged.

Advantages of rice(paddy) dryer

1. Energy saving: The rice dryer adopts hot air circulation technology, which can effectively utilize heat energy and reduce energy consumption.

2. Improve drying efficiency: The rice(paddy) dryer adopts an automatic control system, which can automatically adjust the temperature and wind speed, and accurately dry the rice according to the actual situation. This intelligent control not only improves the drying efficiency, but also shortens the drying time.

3. Ensure quality: The rice(paddy) dryer can accurately control the drying temperature and wind speed to avoid quality problems such as rice bursting due to excessive drying. At the same time, the impurities and odors in the rice can be effectively removed during the drying process to improve the storage quality of the rice.

4. Reduce costs: Due to the improved drying efficiency and quality, the rice(paddy) dryer can reduce drying time and energy consumption, thereby reducing drying costs. In addition, the dried rice is easier to store and transport, which also indirectly reduces storage and transportation costs.

5. Environmental protection and safety: The rice(paddy) dryer adopts pollution-free and noise-free hot air circulation technology, which meets environmental protection requirements. At the same time, no chemicals need to be added during the drying process, ensuring the safety and hygiene of rice.

Dingli rice(paddy) dryer has been widely used in the field of rice storage and processing with its advantages of high efficiency, energy saving, environmental protection and safety.
