Seed dryer starts drying 1000 tons of corn seeds

Why do seeds need to be driedSeeds are the reproductive system of seed plants and play an important role in the continuation of species.

However, seeds cannot be sown at any time. In order for the seeds to continue sowing, growing, and reproducing in the following spring or after a certain period of time, they need to be dried or refrigerated to maintain their activity.

However, refrigeration often damages the growth of seeds themselves, so the method of preserving seeds is often to dry and store them.

After maturity, the seeds are first naturally dried for a few days and then dried. The main function of air drying is to dehydrate the surface of seeds and make them seedable, while also eliminating seeds that cannot be sown. After drying, lay the seeds flat in the drying tray and place them in the dryer. The temperature adjustment of the dryer should not exceed 40 degrees Celsius. If the temperature is too high, it will damage the activity of the seeds and prevent them from growing.

Seeds with a dehumidification rate of less than 20% will only enter the dormancy period after complete dehydration. The dormancy period of seeds can last up to 5 years. Using a low-temperature constant temperature seed dryer to completely dehydrate seeds can improve their storage time.

According to data, the annual corn production is constantly increasing. However, due to the influence of climate and environment, the moisture content of corn is often high, which is not conducive to storage and sales.

The corn dryer can reduce the moisture content in corn from around 20% to below 13% to meet the quality requirements and storage needs of corn. At the same time, a corn dryer can improve the quality and storage stability of corn, reducing the spoilage and loss of corn during storage. Therefore, corn dryers have broad application prospects in agricultural production.

Firstly, the heating system is the core component of the corn dryer. It usually uses a burner or electric heater to provide a heat source. Burners can burn fuels such as coal, diesel, gas, biomass particles, etc.producing hightemperature hot air, while electric heaters convert electrical energy into heat. These heat will be conducted   to the hot air box of the dryer, causing the temperature inside the hot air box to rise.

Next, the ventilation system plays a role in evenly blowing hot air into the corn dryer. Ventilation systems typically consist of fans and ducts. The fan generates airflow through rotation, sucks in hot air from the hot air box, and then transports it to the corn pile through the air duct. In a corn dryer, hot air comes into contact with corn particles and evaporates the moisture in the corn. At the same time, the ventilation system can also discharge the evaporated moisture out of the dryer to maintain the humidity of the drying environment.

Afterwards, the control system monitors and adjusts the operation of the corn dryer. It usually consists of a temperature sensor, a humidity sensor, and a controller. The temperature sensor is used to measure the temperature inside the hot air box, the humidity sensor is used to measure the humidity of the drying environment, and the controller automatically adjusts the operating status of the heating system and ventilation system based on the feedback signal of the sensor to maintain the stability of the drying environment and the drying quality of the corn.

In agricultural production, corn dryers play an important role, providing strong support for the production and processing of corn. I believe that with the continuous advancement of technology, the performance and efficiency of corn dryers will be further improved, making greater contributions to the development of agriculture.
