Dish pelletiser with activator
FIELD: process engineering.
SUBSTANCE: invention may be used in food and pharmaceutical industries. Dish pelletiser with activator comprises inclined dish arranged to revolve in case with cover, dish drive, material loading and unloading branch pipes, nozzles, wall and bottom blades, driven activator arranged in cover perpendicular the dish bottom with clearance relative to dish bottom and wall. Activator drive is equipped with axial vibrator. Said activator is composed of a rod with frames arranged perpendicular to the flow of material being pelletised wherein radial plates are secured at two pints, that is, at the rod and at the frame.
EFFECT: faster pelletising, higher yield of 0,75-2,5 mm-fractions, uniform shape and density, reduced moisture content.
The invention relates to devices for granulating materials and can be used in food, pharmaceutical and other industries, for example, to obtain a dry granular Breakfast, consisting of a mixture of sugar, starch, whey powder and concentrated juice.
Known plate granulator (EN 2105601 C1, 6 B01J 2/14, 1998), where the introduction of regulatory plates, table-knife and separating device creates an additional effect on granule for their active rolling and ensures the removal of granules of the desired size.
However, due to the increased stickiness of the food mass by a separating device will be a build-up of material and, as a consequence, the separation device will not ensure effective allocation of granules of the desired size.
Known plate granulator with activator (EN 2209662 C2, 6 B01J 2/14, 2001), comprising a housing with a cover, which is installed with the possibility of rotation of the inclined plate, drive plate, the bumper and bottom knives, entered the activator with the drive. The activator is installed perpendicular to the bottom of the plate with a gap relative to the bottom and sides of plate 5-10 mm. Activator located in an area where the focus of the largest granules and coalescent units. Shock blade activator, on the one hand, the actuator is t to the destruction of large granules and aggregates, on the other hand, initiates granulometrie in the source material. Drive rotation of the activator is made adjustable (frequency of rotation), which allows to actively influence the process of granulation, in particular on the size of the resulting granules.
However, is the violation of the roll of material and the associated process of segregation of granules, which in turn will not provide effective obtain pellets of a given size, shape, density, moisture, etc.
The objective of this invention is to provide a disc granulator, which due to the modernization of the structural element - activator reduces the time of granulation, increased release of granule fractions of 0.75-2.5 mm, uniform in quality (shape and density), reduced the moisture content of the granulate.
The problem is solved as follows. The activator drive is equipped with axial vibrator, and the activator is represented in the form of a rod with two frames, installed perpendicular to the moving flow of the granulated material in which the radial plates are attached at two points on the rod and on the frame. The invention is illustrated by drawings 1-4.
Figure 1 shows a diagram of disc granulator with activator in section a-A. figure 2 and 3 shows respectively a top view and in cross section a-a disc granulator with activator is showing conditional trajectories of the motion of the granules and the capture zone of the activator.
Disc granulator with activator contains an inclined plate 1 (diameter D, depth H, radius R and angle to the horizon α)contained in a housing 2 with a lid 3, the drive plate, the discharge pipe 4 to output of finished products, the loading pipe 5 to enter retur nozzle 6, the bottom wall and the knives 7 and 8 activator 9, mounted at a distance relative to the bottom and side of plate 1, is equal to 5-10 mm, and the area between 3-5 hours when relative rotation of the plate counterclockwise, the shaft of the activator 10, the drive rotation of the activator 11 and the bearing unit 12.
When conditional consideration of plate 1 in the form of hours (figure 2) activator 9 is located in the area between 7-9 hours under the condition of rotation of the plate in the clockwise direction, and the area between 3-5 hours while rotating counterclockwise.
Figure 2 and 3 was also observed trajectory: a trajectory (relative) motion of the source material; b, C, d, e - the trajectory of the pellets as they grow; e - trajectory of the largest granules, W - a capture zone of the activator.
Figure 4 is a diagram activator granulator, which consists of a rod 13 with two frames 14, which is located radially narrow plate 15, secured at two points, namely on the rod 13 and the frame 14.
Disc granulator operates as follows.
Inclined plate 1, installed in the building is 2 with a lid 3, is driven by the actuator counterclockwise with a given angular velocity W.
Through the feeding pipe 5 is injected recur, for example a mixture of melkorazdroblennyh starch, sugar, whey powder.
As a result of granules located on an inclined rotating plate 1, gravity and friction forces they receive complex movement (schematic lines a, b, C, d, e) around the zone of movement of the largest granules located inside the zones bounded by the line E.
Actively rolling due to the natural shedding of the granules are coated in the liquid phase, for example, concentrated juice, through a nozzle 6. In addition, clinging to the bottom and side surfaces of the plate pellets difficultly enough cleaned off the bottom of the knife 7 and the wall with a knife 8, sliding respectively on the bottom and side surface of the plate towards her movement.
As the growth of large granules fall into the capture zone of the activator W, where exposed to the activator, is equipped with a vibrator that rotates with frequency p, making a reciprocating motion. Then due to the centrifugal force of the pellets roll over the side of the plate in the discharge pipe 4 and are derived from the disc granulator for further processing.
Thus, the active mixing of the material activator the 9 increases the uniformity of the granules, derived from multi-component mixtures, reduced time of granulation. Shock-vibrational impact plates 15 activator for moving in laminar flow polydisperse environment contributes to the adhesion of particles, the emergence of germ granules at a lower humidity. The density of the granules will increase, which will allow you to use different drying methods, not used previously.
Disc granulator with an activator containing an inclined plate mounted rotatably in the housing with cover, drive plate, loading and unloading spouts the granulated material, the nozzle wall and bottom knives, the activator with the rotation drive mounted in the lid perpendicular to the bottom of the plate with a gap relative to the bottom and sides of plate 5-10 mm in the area between 3-5 hours under the condition of rotation of the plate counterclockwise, characterized in that the activator drive is equipped with axial vibrator, and the activator is made in the form of a rod with the framework set perpendicular to the moving flow of the granulated material in which radially arranged plates, fixed at two points on the rod and on the frame.
