Abstract
A coating apparatus with a coating chamber configured for receiving a particulate, a horizontally-oriented rotor having a plurality of paddles mounted thereon, the rotor and the paddles defining a liquid injection path fluidly connected to a liquid injection system, the liquid injection system arranged to supply a liquid under conditions suitable to continuously coat the particulate in a manner that substantially reduces formation of caked solid-liquid mixture on inner walls of the coating chamber.
Claims20
A coating apparatus comprises a horizontally-oriented rotor rotatable about a longitudinal axis, the rotor being centrally positioned in the coating chamber, with the rotor having a plurality of mixing paddles mounted thereon, the apparatus further comprises a controllable system for delivering liquid along a path from a liquid source to the chamber interior, and in turn, onto the particulate material, the liquid traveling in the coating chamber along a predetermined liquid trajectory in the coating chamber, the liquid trajectory being controllable by the controllable system.
A coating apparatus comprising:
- a coating chamber configured for receiving a particulate;
- a horizontally-oriented rotor rotatable about a longitudinal axis, the rotor having a plurality of paddles mounted thereon, the rotor and the paddles defining a liquid injection path fluidly connected to a liquid injection system, the liquid injection system arranged to supply a liquid under conditions suitable to continuously coat the particulate in a manner that substantially reduces formation of caked solid-liquid mixture on inner walls of the coating chamber.
A process of forming a granular product from a dry powder, comprising:
- providing a horizontally-oriented coating apparatus that receives the dry powder, the coating apparatus having a coating chamber, a hollow rotor with a plurality of paddles mounted thereon;
- injecting a liquid through a central aperture defined on the rotor, the liquid flowing through the central aperture along a longitudinal axis of the rotor, the liquid flowing out of apertures defined on each paddle, and directly contacting the dry powder;
- coating and/or mixing the dry powder with the liquid, thereby binding the powder;
- and
- conveying the mixture of dry powder and liquid out of the coating apparatus by rotating the rotor.
