(54) GRANULATED PRODUCTION LINE

5ШД. Тш I MATERIALS

.0mm "" m1 "-" - - - - ivatel and tablet machines connected to the last one.

In addition, the container for collecting and leveling the wetting of the granules is mounted on it at a distance of 0.5-0.7 in height from its neck with the tip facing up.

-Also, in addition, the turnstile is installed on the same level with the gas distribution grid and the drying grate of the drying chamber.

The drawing shows a diagram of the production line of granular materials.

The line for the production of granulated t1p ial6v contains installed along the technological process bunkers 1 source components, dispensers 2 and 3, feeder-4, apparatus for preparing the binding substance, mixers 5, granulator 6 of wet granulation, drying chamber 7 mounted at csnlIl chamber and in series: interconnected granulator 8 dry granulation, a tank 9 for collecting and leveling the moisture of the granules, and a plant for dusting dry granulate and tabletting it.

The binder binding device includes dispensers 10 and 11 of solids and water, a device for preparing a starch suspension and brewing it, mounted as a dispenser (not shown) and a brewing chamber 12 with a steam jacket 13 and a mixer 14 and metering pump 15 for supplying starch paste.

The plant for dusting and tabletting a dry granulate includes dispensers 16 granulates and dusting agents, a mixer-powder feeder 17 mounted under them and connected to the last conveyors 18 and 19 of the tablet machines 20.

In order to prevent the formation of material arches in the tank 9, a cone 21, with its tip pointing upward, is mounted at a distance of 5-0.7 in height from the container mouth to collect and level moisture.

The drying chamber 7 has a gas distribution grid 22 and a turnstile 23 for unloading material, the latter and the gas distribution grid being installed on the same level. An apparatus for preparing a binding substance is mounted above the mixer 5.,

Lini works as follows.

The initial components (raw materials) are fed into the bunker 1 and from it to the dispenser 2, from which, in turn, through the patrol post: they feed into the aggr1 B of the mixer 5. Other bulk components also flow into the mixer 5 at the same time. At the same time, a binder is prepared, for which dry starch and water with a temperature of 20 ° C using dispensers 10 and 11 of. step in. mixer 14, and from it

The prepared suspension is sent to the chamber 12 for continuous welding of starch paste, which also receives a metered amount of water with a temperature of 95-100 C. Starch paste with a pump 15 pushes pump 1 into the mixer 5 simultaneously with bulk materials, such as norsulfazole and dry starch. During mixing in the mixer, the material moves to the zone

- unloading, which ends with a screw with a reverse pitch (not shown), which excludes the possibility of pressing the mixed mass, and from there - into the granulator, located in the separator part of the drying chamber

0 7-. Mixing time - 3-5 minutes.

The wet mass is forced through a perforated grid. The size of the holes 1 Satrix can be love

5 and determined by the composition of the granulate. Under the matrix there are knives (not shown in the drawing), cutting off the granules pressed through the holes of the lattice, which, falling freely in the vertex,

The Q tick drying chamber and, meeting the flow-heated agent, are dried and then fall into the fluidized bed. The vertical part of the drying chamber 7 is for drying

grams of granular material, as well as to filter dusty air passing through the fluidized bed. The fine fraction formed in the fluidized bed, meeting with the wet granules in the vertical part of the apparatus, is deposited on them, as a result, the entrainment is significantly reduced. Drying time 10-15 minutes.

The turnstile dried granular mate rial is unloaded from the drying chamber into the granulator tor 8 of the dry rovni. Due to the positioning of the turnstile at the level of the gas distribution grid of the grid, it is possible to regulate the material loading over the entire layer. The material then flows through the nozzle into the container 9 to collect and level the moisture of the granules. The granules and auxiliary powder products through dispensers enter the mixer 17. Mixing time is 1-2 minutes. Powdered material is conveyed by conveyors 18 and 19 supplied with dumpers to the hopper of tablet machines 20. The finished tablets are fed to a perforated belt conveyor (not shown), dust is removed using dust debris installed between conveyor belts and transported to the packaging .
