The present invention is an automated packaging apparatus utilizing a rotating assembly of elongated slats containing cavities to receive discrete pharmaceutical, vitamin, or food products. Quantities of discrete products such as tablets, capsules, or gels are deposited into the hopper of the apparatus. The apparatus then dispenses the discrete products into containers moving on a conveyor system such that each container receives a predetermined quality and quantity of pharmaceutical, vitamin, or food products. While operating at high speed, the apparatus inspects, counts, identifies and analyzes each product deposited into the containers and maintains electronic records describing the status of each product. In the event any errors occur the apparatus produces various alerts to inform the operator. The presence of foreign products or objects may cause the apparatus to instantly stop the entire system including peripheral equipment. A series of Good Manufacturing Practice protocols can then be enforced as per FDA requirements.
