When I was choosing grain cleaning machines for my farm, I took into account several important factors to choose the most efficient and durable equipment. First of all, I paid attention to the machine's performance. For my farm, it is important that the machine can process large volumes of grain in a minimum amount of time. Of course, the type of sorting that the equipment offers is also important. For example, optical color sorters, such as those presented on the website https://metragraincleaner.com/product_c … r-sorters/, really distinguish grain by color, which helps not only get rid of contaminants, but also improves the quality of the final product. Ease of maintenance was equally important to me. I was looking for machines with a simple control interface and accessible parts for maintenance and repair. It is important that the equipment works stably in all conditions, and that the service support is top notch. To achieve this, I chose models with a good reputation in the market and positive user reviews.
