311 results about "Crop residue" patented technology

There are two types of agricultural crop residues. Field residues are materials left in an agricultural field or orchard after the crop has been harvested. These residues include stalks and stubble (stems), leaves, and seed pods. The residue can be ploughed directly into the ground, or burned first. In contrast, no-till, strip-till or reduced till agriculture practices are carried out to maximize crop residue cover. Good management of field residues can increase efficiency of irrigation and control of erosion. Simple line transect measurements can be used to estimate residue coverage. Process residues are materials left after the crop is processed into a usable resource. These residues include husks, seeds, bagasse, molasses and roots. They can be used as animal fodder and soil amendment, fertilizers and in manufacturing.

High energy efficiency biomass conversion process

Improved, fuel-efficient systems are provided for the processing of biomass, such as wood or crop residues, food waste or animal waste in order to selectively obtain torrefied and / or carbonized final products. In general, the processes involve thermally drying incoming biomass using a dryer employing the hot gas output of a fuel-operated burner. Next, the dried product is torrefied in an indirect torrefaction reactor so as to evolve light volatile organic compounds which are used as a gaseous fuel source for the burner. The torrefied product can be recovered, or some or all of the torrefied product may be directed to a carbonization reactor coupled with a reactor burner. Carbonization serves to remove most of the remaining VOCs which are used as a gaseous fuel input to the dryer. In certain instances, portions of the dried biomass are directed to the burners, as an additional source of fuel.

Crop processing method and apparatus

In a method for processing swathed crops, the entire cut crop is picked from the field and transported to a processing facility located away from the field. The processing facility has a threshing apparatus which separates grain from the cut crop, leaving a crop residue comprising plant stalks, chaff, and other constituents of the cut crop. The separated grain is conveyed from the threshing apparatus to a grain storage bin or directly to a transport truck for delivery to a grain terminal. The processing facility also includes crop residue handling means for conveying crop residue to a bulk storage pile, to a baling machine, or to some other selected location. The method makes field baling operations unnecessary, thus expediting the total removal of the crop from the field.
