Demonstration of the operation of the wheat washing machine
A wheat washing machine is a device used to clean wheat grains, and its working principle can be divided into the following steps:
1. Load wheat grains: Add the wheat grains to be cleaned into the hopper of the wheat washing machine.
2. Pre cleaning: Before starting formal cleaning, the wheat washing machine usually undergoes pre cleaning. This step will use various screens and airflow systems to screen out larger impurities such as stones and crushed straw.
3. Soaking: Spray clean water onto the wheat grains through a sprinkler system, allowing them to soak for a period of time. This can dissolve or float the dust and pollutants on the surface of the wheat grains, making it easier for subsequent cleaning.
4. Friction cleaning: After soaking for a period of time, the wheat grains will enter the main cleaning section. Here, there are usually devices such as brushes, rubber rollers, and screens. When the wheat grains pass through these devices, the brush and rubber roller will rub to remove pollutants from the surface of the wheat grains. Meanwhile, the sieve can filter out smaller impurities.
5. Rinsing: In order to thoroughly clean the wheat grains, the wheat washer sprays clean water onto the wheat grains again after rubbing and cleaning. This can wash away residual pollutants and make the wheat grains cleaner.
6. Discharging impurities: During the cleaning process of the wheat washing machine, some sewage and impurities will be generated. These sewage are discharged through the drainage system, and impurities are separated and eliminated through vibration screening or other separation devices.
7. Drying: Clean wheat grains usually contain a certain amount of moisture. To avoid mold or spoilage of wheat grains, the wheat washing machine uses hot air or other methods to dry the wheat grains to a suitable level of moisture.
8. Storage or processing: The cleaned and dried wheat grains can be used for storage or subsequent processing, such as milling, fermentation, etc.
The above is the basic working principle of a wheat washing machine. Different models of wheat washing machines may have some differences, but overall, they all clean the original wheat grains through steps such as cleaning, screening, and drying, providing high-quality wheat grain materials for subsequent processing.
