Abstract: A system for melting adhesive comprises a melter, a feed system, a pump, and a controller. The melter has a melting volume, and receives and melts adhesive. The feed system supplies unmelted adhesive to the melter, while the pump pumps melted adhesive from the melter. The controller directs the pump to pump melted adhesive at a throughput rate such that the ratio of the melting volume to the throughput rate is a dwell time less than a discoloration time of the adhesive. In some embodiments, the controller also directs the feed system to replenish adhesive in the melter as a function of adhesive level in the melter.

Abstract: A hot melt dispensing system including a container for storing adhesive pellets, a feed system for transporting adhesive pellets from the container, and a blower. The blower is positioned with respect to an inlet of the feed system for applying a flow of air for agitating the adhesive pellets and moving the adhesive pellets toward the inlet.

Abstract: A system includes a base, a melter, and a heater. The base defines a basin with an outlet connected to the basin. The melter is above the base and has an upper end for receiving hot melt pellets and a lower end adjacent to the basin so that hot melt liquid can flow from the melter through the basin to the outlet. The heater is attached to at least one of the base and the melter, and the melter is releasably attached to at least one of the base and the heater.
