Continuous press for dehydrating pulps

A continuous press adapted to press products such as vegetables, fruits, fodder or the like, comprising:

• an external crown;
• a central wheel mounted for rotation on a shaft and having a diameter smaller than the diameter of said crown, said wheel being mounted within said crown so as to form a rotary assembly of two cylinders internally tangent with respect to each other and between which said products are pressed;
• at least one support on which freely-rotating spools are mounted, said spools bearing upon the outer circumference of said external crown;
• and means for tangentially urging said crown and said wheel against one another to impart a contact force between them, said means comprising first and second pairs of levers located on either side of said rotating assembly, said first pair of levers being pivotally mounted on said shaft on which said wheel is mounted and said second pair of levers being pivotally connected to said at least one support on which said spools are mounted, said two pairs of levers being pivotally connected at one of their end regions about a common point, said urging means further comprising an adjustable tightening means provided at the other of the end regions of said pair of levers for urging said respective pairs of levers towards or away from one another for varying the force with which said spools bear upon the outer circumference of said external crown to correspondingly vary the force of contact between said crown and said wheel.
