Since 2000, Sasov Biofarm has been the largest organic pig farm in the Czechia. The low daily gains of pigs in fattening and the high consumption of mixtures were caused, among other things, by the low content of NL substances in the feed mixtures. One of the protein sources used was dried alfalfa. First in the form of purchased hot-air drying products and then as flour created by shredding whole dried alfalfa. In 2011, a drying room for round bales was built on the biofarm using heat from its own biogas station. The production of alfalfa for feeding pigs was ensured in very good quality and in sufficient quantity. Due to the high fiber content, which limits the higher representation of alfalfa in feed mixes, it was subsequently decided to build a line for separating the leaves and stalks of legumes. For the actual separation, several machines with using different principles. These were vibrating screen sorters and drum cleaners. The fine fraction in both types of separators provided an increase in crude protein content by 10% and a decrease in crude fiber content by 15%. Network separation system appeared to be more promising, where the settings of the device can be changed by simply changing the networks. For a drum system, the entire separation drum with defined openings would have to be replaced. For better handling and storability, it was decided to supplement the ungrouping and separation line with granulation presses and dispatch equipment. With this assignment, a line was built at the farm as part of the tender process and with the support of the rural development program for unbundling legumes in a dry state, subsequent separation of leaves and stems, and product shaping, including transport routes, intermediate containers, mixing and dispatch equipment.
