Title: Method of harvesting peat
IPC: E21C49/00
Filed: 1975-01-15
Abstract: 1488256 Harvesting peat FARMURA Ltd 15 Jan 1975 [8 Feb 1974] 05919/74 Heading E1F A method of harvesting peat involves forming peat into a slurry in a peat bog, and feeding the slurry to a centrifugally acting, liquid-extracting device in which a flocculating, agglomerating or coagulating agent is added to the slurry as it enters the device. Preferably the agent is a polyelectrolyte and is mixed with water in the ratio of about 0.1% to 99.9%. The polyelectrolyte-water mixture is added in the ratio of about 10% to 90% slurry. The moisture content of the peat is reduced to about 70% to 80% in the liquid-extracting device. The moisture content can be further reduced by means, such as a conveyor band dryer, a pneumatic dryer/cooler, a pneumatic flash dryer, or a rotary dryer, to about 50% if the peat is to be used for horticultural purposes or to about 10% if the peat is to be suitable for fuel. To obtain the peat from the bog can involve first digging a trench in the bog and feeding the peat from the trench into an adjacent vessel to be formed into a slurry by an agitator before passing through a macerator prior to being pumped to the liquid-extracting device, and then placing the vessel in the trench for the extending of the trench as peat is further dug out therefrom. Extracting liquid from the device can be hosed under pressure back into the trench to facilitate loosening of the peat and forming the slurry.
