Abstract
The present invention relates to a method and device for drying mash-products, and more particularly to a 2-step device for drying mash-products comprising a first drying unit (a flow rotary drying unit) and a second drying unit (a mixing rotary drying unit), the first drying unit and the second drying unit being arranged in series, and a 2-step method for drying mash-products.
Claims31
A method for drying mash-products in a system including a first drying unit, a second drying unit, and a conveyor, the first drying unit comprised of a first rotatable drum and the second drying unit comprised of a second rotatable drum, the method comprising the steps of:
- performing a first drying operation in said first drying unit, said first drying operation comprised of the steps of:
- blowing cut mash-products into said rotatable drum;
- rotating said first rotatable drum;
- blowing hot wind into said first rotatable drum;
- and
- discharging first dried mash-products from said first rotatable drum;
- and
- performing a second drying operation in said second drying unit, said second drying operation comprised of the steps of:
- rotating said second rotatable drum;
- blowing hot wind into said second rotatable drum, said hot wind simultaneously being circulated within said second rotatable drum and being discharged out of said second rotatable drum;
- throwing said first dried mash-products into an input opening of said second rotatable drum via said input conveyor;
- dropping said first dried mash-products down said input opening;
- and
- discharging second dried mash-products through a discharging opening.
A mash-product drying apparatus, comprising:
- a first drying unit comprised of:
- an inlet for receiving mash-product;
- and
- an outlet for outputting mash-product dried to a first moisture content;
- and
- a second drying unit comprised of:
- an inlet coupled to said first drying unit, said inlet receiving said mash-product at a first moisture content;
- a rotating drum including a corrugated portion on an internal surface;
- and
- an outlet for outputting mash-product dried to a second moisture content, said second moisture content being lower than said first moisture content,
- wherein said corrugated portion serves to throw mash-product drying in said rotating drum.
A method of drying mash-products, comprising:
- drying mash-products to a first moisture content in a first drying unit;
- and
- drying said mash-products at a first moisture content in a second drying unit including:
- rotating said mash-products at a first moisture content;
- throwing said rotating mash-products;
- and
- discharging mash-products dried to a second moisture content lower than said first moisture content.
A multi-stage air food drying device, comprising:
- a first rotary drying device, comprised of:
- a food intake for receiving food having a pre-drying moisture content;
- a rotatable drum section having a substantially smooth internal volume;
- a hot air intake for receiving hot air at a first velocity and a first temperature, said hot air drying said food having a pre-drying moisture content within said rotatable drum section;
- and
- an outlet for discharging food dried to a first dried moisture content;
- and
- a second rotary drying device, comprised of:
- a dried food intake for receiving said food dried to a first dried moisture content;
- a rotatable drum section having a corrugated internal volume;
- a plunger for changing an inclination angle of said rotatable drum section;
- a hot air intake for receiving hot air at a second velocity and a second temperature, said hot air drying said food dried to a first dried moisture content within said rotatable drum section;
- a plurality of dampers disposed within said second rotary drying device which adjust a flow rate of said hot air within said second rotary drying device;
- and
- an outlet for discharging food dried to a second dried moisture content lower than said first dried moisture content.
