Definitions

  • TITLE PROCESS AND APPARATUS FOR DRYING PRODUCTS OF VARIABLE PARTICLE SIZE, CHIPS AND GRANULES
  • the present invention relates to a process and apparatus for drying fuel products or products in general having a variable particle size, such as chips and granules .
  • an apparatus for drying products in a range from agroindustrial products, such as cereals, to recovered-reused products and byproducts derived from industrial and agroindustrial processes.
  • the drying processes concerned herein are designed for reclamation of waste, sludge in general (of food-processing or industrial origin) , waste oil, sawdust, pellets, fertilizers, wood flour and/or chips , humus , food scraps , low specific weight ground products .
  • the technology proposed herein provides a more convenient process for drying the above products and more generally relates to any product not in solid/pressed/extruded state, i.e. products having a poor degree of cohesion due to the amount of water therein .
  • the process is also suitable for use with slurry or even liquid products, resulting in corresponding powders upon drying .
  • the object of the present invention is to provide a system and process for drying fuel products or products in general having a particle size, which affords considerable advantages, including: much shorter drying times as compared with the large air-volume systems of the prior art, dramatically reduced amount of flue dust, i.e. reduced product pollution.
  • FIG. 1 is lateral sectional view of a first embodiment of a dryer of the invention

Abstract

L'invention concerne un procédé de séchage de produits de granulométrie variable, dans lequel ledit produit ou matériau (2) de granulométrie variable est transporté sur au moins un moyen de transport (4) et un jet d'air de séchage/refroidissement à grande vitesse atteint ledit matériau (2), ledit matériau (2) étant enfermé pendant ladite étape de séchage de manière à limiter les pertes de poudre du produit. Le produit (2) est retenu entre les deux côtés (4a, 4b) de deux moyens de transport adjacents correspondants (4), placés l'un au-dessus de l'autre pour définir plusieurs plans de manipulation de matériau (2), le côté (4a) étant le côté sur lequel le matériau (2) est transporté. Autrement, le matériau (2) est placé entre le moyen de transport (4) et une plaque stationnaire ou mobile (9) située au-dessus dudit moyen (4).
