In the paper the national technological achievements in the extraction of raw materials has been discussed. Technology for extraction of raw materials in industrial-scale plant was designed and implemented in the Fertilizer Institute (INS) in Puławy. In 2000 INS launched as a first in the country, as well as in the countries of Central and Eastern Europe, industrial scale plant for the extraction of hops of capacity of 3000 t/y, operating at pressure up to 300 bar, sufficient to meet the national demand for processing of Polish hops and the hop processing service for other customers. The developed technology ensures high efficiency recovery of resins and essential oils, and meets the highest quality requirements. In mid-2011 INS started commissioning of another plant for the extraction of raw plant materials, also using technology developed in the INS. The plant with a nominal capacity of 2000 t/y belongs to universal type plant and will be able to produce extracts from many different plant materials. The plant will be able to work under pressure to 530 bar, and will be able to produce extracts from peppers or other plant raw materials which require higher processing pressure.
