FIELD: agriculture. ^ SUBSTANCE: method to produce granulated peat for communal-general needs includes granulation, radiation of granules with microwave field, and blowing of granules. At the same time granules are formed from peat with moisture from 50% to 75% under pressure from 0.4 to 0.8 MPa, formed peat granules are transported along belt conveyor, heating them in the field of alternating electromagnet oscillations up to temperature from 70C to 80C, afterwards cooled with air flow down to ambient temperature. At the same time frequency of alternating electromagnet field makes from 2400 to 2600 MHz. ^ EFFECT: simplified drying and granulation of peat, reduced energy intensity and cost of method. ^ 2 cl |
