Abstract
In many manufacturing industries, powders should be weighed and dispensed as a part of the routine
production process. In these scenarios, workers must prepare power batches based on the material
requirement manually. This manual process reduces the efficiency of overall production. Existing
powder dispensing systems have issues including material and time wastage, human errors in the
measurements. Since some powders are toxic to humans, works should avoid direct contact with the
material. This study proposes a system to address these issues which are equipped with a screw
conveyor and electronic weighing measurement. Also, the proposed system has features including
automatic quantitative, Speed control. Further, Screw conveyors have an agitator to give vibration
motion to the screw conveyor to ensure the Powder quickly comes to the screw conveyor. A valve is
installed at the point where the powder exists, and the valve opens. Then the Powder comes out to
the screw conveyor the Powder starts to dispense into the container. The load cell system collects
data and measures the amount of powder that falls through the conveyer. PID unit is used to control
the speed of the conveyor. The powder measuring machine is suitable for food additives, flavors and
fragrances, flour, milk powder, protein powder, solid drink, sugar, monosodium glutamate,
pesticides, veterinary drugs, detergents, enzymes, chemicals, and other powder (powder, super fine
powder). The dispensing system is having 85% efficient 90% accurate than the conventional
methods used in local manufacturing facilities.
