  • a general scheme depicts one of the possible phases to which the cereal to be transformed can be subject.
  • cylinders (A) through which the product enters and where the initial milling of the raw product is carried out.
  • B pneumatic raising assembly
  • screens (C) These screens are composed of a series of several-mesh nylon screens through which the products sub-divide and reach new phase of processing.
  • Such new phase begins in another cylinder going or not through intermediated blenders (D) the purpose of which is to prepare the product better for the following phase.
  • D intermediated blenders
  • the process will be repeated as many times as it is necessary until one obtains the maximum of extraction of the cereal to be transformed, it being pointed out that in many phases it is necessary to useremovers (E) the function of which is to eliminate possible scales that are formed during the milling.
  • Another important item comprises utilizing such new concept in already-existing classic systems, processing entire phases, increasing the overall capability, not needing, therefore, a new system but using the existing one, the new machine being arranged at any point of the process.
  • the aims of the applicant in the subject patent refer to a new concept of cent ri f ug al screening through rotative blenders surrounded by a cylindrical screen jacket composed of multiple individually removable boards, which processes the screening of all the products of an entire phase of the industrialization process and that can be employed in all the phases. In any of such phases final products are obtained and the machine can simultaneously carried out the raising, screening, division and removal of the products.
  • FIGURE 1 external view of the structure.
  • FIGURE 2 internal view of FIGURE 1.
  • FIGURE 3 general view of the cylindrical screens jacket composed of multiple semi-cylindrical boards that can be individually removed.
  • FIGURE 4 view of the screen boards showing the semirims and angles supporting it.
  • FIGURE 5 demonstration of how the screen is mounted on the structure.
  • FIGURE 6 schematic view of the blenders shaft for great diameters.
  • FIGURE 7 ditto Figure 6,demonstrat ing the screens, too.
  • FIGURE 8 schematic view of the blenders shaft, in a plan.
  • FIGURE 9 detail of attachment of the blenders to the shaft.
  • FIGURE 10- schematic view of the blenders shaft for smaller diameters.
  • FIGURE 11 schematic view of the utilization of several machines for great lenghts.
  • FIGURE 12 schematic view of the classic systems and processes.
  • the machine comprises two head assemblies connected by four "T-shaped" irons (1) locat ed ymmetrically forming a circular area and with the purpose to support the structure (2) of the machine which is formed by removable doors set and attached to the "T" irons (1) by means of simple snap locks allowing total access to the multiple semi-circular screens boards responsible for the penetration of the cereals.
  • the semi-circular screens boards (3) are attached by snap locks (4) to two intermediate irons (5), also in the form of a "T", which are, in turn, bolted to the interal ring (6) and welded to the head assemblies.
  • the present invention is characterized by the plurality of individually removable boards that compose the cylindrical screens jacket, which, due to the plurality of boards, are subject to a scale as to the number of type of meshes suitable to the several mesh measurements.
  • the cylindrical screens jacket can be composed of several meshes as shown in the divisions of Figure 3, as well as it improves a systems of frame of the screens in the respective boards.
  • Each board which forms a semi-circle, is composed of two longitudinal angles (7) united by two, three, four or more semi-rims (8) of flat irons welded to the angles (7).
  • the boards are superposed usually in number of 4 or in greater number, it depending on the desired scaling, and they are attached by snap locks (4) to the intermediate T-shape irons (4) as previously described.
  • the boards will have in the upper part thereof an external ring (10) in sheet metal welded or riveted to the semi-rim coated with felt (11) to fixate the superposed board and seal the junction.
  • the blenders (17) are made of resilient iron or similar material and are attached to the shaft in two parts, bolted to the shaft by two bolts (20) on each side of the shaft and superposed so as to form 90-degree angles with respect to each other. From the last attaching bolt to the end, said blenders (17) are twisted to the desired helical degree for advance or transport of the product and are drilled adjacent the ends where an iron plate (21) is bolted, in an elongate bore, for adjustment of the distance to the metallic screen, said plate being broader to eliminate any void between the superposed blenders.
  • shaft presents the same characteristics and functional principles as the old one, but in this case the shaft (22) of the shaft or spindle (23) is made of seamless steel tube, and the blenders(24) have triple adjustment, that is: the tube (22) is drilled throughly as shown in Figure 10 in symmetric distances, a threaded circular iron bar (25) being passed from the edge of the tube to the end, which bar is tightened, for attachment, by a nut (26) on each side of the tube (22).
  • the iron bar (25) is followed by another nut (28) of each side of the blender for adjustment of the distance from the end of the blener to the screen (3) and also to adjust the vertical advance inclination.
  • the inclination of the blender (24) which directs the product towards the screen, is made by the bolt (29) and lock nut (30).
  • a gutter-shaped sheet-metal, felt-or rubber ⁇ -sealed collar (9) is mounted around the screen (3) and leaned to the external door, the collar having a 30o to 50o slope that crosses the door for ejection of the product; next, the section that carries out the division of the product can be mounted horizontally, this option further facilitating the approach of the product to the next machine in the processing.
  • the entrance (12) of the product to be screened is in the lower part of the machine, the fine product being screened first, then going through the screen and falling into the void (15) existing between the structure (2) and the cylindrical jacket composed of multiple screen boards (3) of s emi- c i r cu l ar shape, crossing the openings in the lower head assembly of the machine, reaching the funnel (31).
  • the product of greater mesh size that did not crossed the screen is ejected from the upper part (32) of the machine.
  • the machine can als o be mounted horizontally.
  • the raising beyond six meters although it can be made by one single machine with connected shafts and intermediate internal bearings, is preferably carried out in two, three, or four steps as shown in Figure 11, thus avoiding connected shafts and internal bearings, each part having only one rolling bearing in each head assembly, and a snap bearing in the lower head assembly, all of them being duly sized and easily reacheable.
  • the driving is individual by means of electric motor, through belt in the upper head assembly.
  • the upper exit (32) of the machine is provided with an oppening covered by a sheet metal cover held on the upper part with a shaft or two pins that can rotate easily in case of clogging in the product flow beyond the machine.
  • the machines which are supplied in modules in order to provide great lenght, have their structures reinforced by an iron arc divided into four parts bolted to the *T* irons at symmetric distances.
  • the attachment of the machine is made by means of bolts that hold it on angles welded to the floor and walls at proper distances.
  • the versatility of the present invention must be pointed out for besides being capable to be utilized in all phases of the industrialization process including the first phase, allways obtaining final products and alleviating noticeably the subsequent phases of the processing, the machine being capable to be made in several different sizes, so that it is being possible to suit it to the availability of space in already-existi installations, and with the characteristic that it can be mounted verticaly and horizontally.
  • the new concept and great advantage of the present invention are in the fact that it can carry out simultaneously, besides screening, the raising, division and removal of the product in one single machine consequently eliminating the utilization of the machines utilized in the classic schemes of industrialization, it being also characterized by the simplicity and lightmess of the structure supporting it, by the easily and totally removable external doors by simply handling the snap locks permiting, total access to the screens jacket; by the innovation of the composition of the screens jackets constituted of multiple boards and removable by simple snap locks; by the innovation of the new concepts or blenders-shafts; as well as by the idealization of a systems of several exists of products by gutter-shaped collars.
