Abstract
A method is disclosed for producing horticultural or fuel peat, in which the peat is removed from a bog, the removed peat is transferred from the bog to a drying field a distance away, in which the moved peat is dried, mainly by exploiting direct solar energy, so that the peat dries due to the effect of the solar radiation and the wind, after drying, the peat is moved from the drying location to further use or storage. The drying field is a special surfaced field, essentially impermeable to water, created for drying, and the peat is spread on the field as a thin 1-15 cm layer of a high-consistency mass, with a solids content of 8-30%.
Claims11
A method for producing horticultural or fuel peat comprising the steps of:
- lifting peat from a bog,
- pumping the lifted peat as a high-consistency mass having a solids content of 8-30% from the bog to a drying field by a pipe and a piston pump abrasively working the peat and breaking the cell structure of the peat to improve drying properties of the peat, the drying field being located a distance from the bog and being a special surfaced field essentially impermeable to water and created for drying,
- spreading the pumped peat on the drying field as a thin 1-15 cm layer,
- drying the spread peat on the drying field, where peat is dried mainly by exploiting direct solar energy, the peat being dried due to the effect of solar radiation and wind,
- moving the dried peat from the drying location to further use or storage.
