Laboratory used for grain sieving device design and manufacturing

After the harvesting of the paddy plant, marketing activities begin. At this stage there are some parameters that determine the price. Size, weight, cleanliness of the paddy are some of them. Accurate detection of these parameters plays an important role in determining product quality and classifying products as standard. It is also important to determine the correct equipment to be used in the production process before the production process. For this purpose, a sieve design has been made that could perform pre-cleaning of the paddy plant from the field. The pre-cleaning sieve is designed in a small size to work as a samplebased laboratory. Samples taken from different points will be screened and the clean product and other waste materials will be separated. As a result of the separation, the amount of clean product will be determined by proportioning to the amount of the product entering and the garbage rate will be determined. Tria-type working sieve mechanism is used. The amount of product placed in the pre-feeding chamber is measured with load cells and feeded in a controlled way. A cyclone design is made in the feeding stage and the light objects in the product are separated by suction. The partially cleaned product is rotated in the sieve and separated in the final product clean container. As a result of the decomposition, the clean product was weighed and the refuse rate was determined. The mechanical sieve system is operated electronically and additional weighing and calculation operations are performed on the microcontroller. Obtained values are shown on LCD.
