The Auto Sample Cleaner weighs an initial sample of grain or seeds (approx. 1.5 liters) in a single operation, starts the SLN 3 sample cleaner, carries out the deawning, opens and closes the deawner floor, carries out the cleaning in a time-controlled manner and automatically weighs the two fractions of small grain and quality grain (cleaned sample). The modern operating software shows the determined masses and the corresponding percentages on the display. If required, the result can be printed out immediately or later. The result consists of the cleaning loss (aspirator discharge, straw and sand sieve) and the quality grain and small grain content. The weighed samples can be taken in collecting trays for further analysis or fall into a large material container (volume approx. 90 litres). The Panel PC stores all results. It has two USB interfaces for barcode scanner, keyboard or USB data storage. For easy processing with MS Excel® the results can be exported to a USB data memory. In addition, the Panel PC has a network connection (RJ45, LAN) for fast, automatic transfer of results to a ERP or merchandise management system. A sample cleaner SLN 3 is required for operation of the Auto Sample Cleaner. Optionally, a pneumatic transport system can be used for automatic sample disposal.
