DEVICES FOR DRYING POULTRY MANURE Russian patent published in 2015 - IPC C05F3/06 

FIELD: agriculture.

SUBSTANCE: device for drying poultry manure comprises a unit of loading, a container with screw channels at the inner surface, made in the form the inner and outer drums mounted coaxially with a clearance, a heat source, a hopper of the finished product, a hopper for receiving mechanical wastes, a casing provided with a fan, a frame with a drive. The inner drum is made of guiding elements in the form of three rectangular perforated strips with an overlaps, bent alternately in opposite directions at an angle of 140° on the notches formed at an angle of 60° to each other and to the longitudinal edges of the perforated strips to form along the length of the strip of the equilateral perforated triangles arranged alternately in opposite directions. The perforated strips are connected to each other along the longitudinal edges at an angle of 70°, forming along the inner perimeter of three polygonal helical grooves of the main direction and two polygonal helical grooves of opposite direction, and on the outer - three polygonal helical lines of the main direction and two polygonal helical lines of the opposite directions. In the salient points there are places of convergence of the sides of six equilateral perforated triangles. Along the perimeter of the drum the overlaps of rectangular shape are formed, arranged in series with gaps one after the other along the polygonal helical lines of the main direction. The outer drum is made of three or more strips of trapezoidal shape with different dimensions of width, with their increase in length of the outer drum from unloading to loading, on which alternately at their opposite sides the zones of reduced cross-section - the incisions with bevelled walls - are made at an angle of 60°.

EFFECT: expansion of technological capabilities and increase in quality of the finished product.
