Description

Technical Field

[0001] The present application relates to the technical field of dryers, and in particular to a hot melt adhesive particle dryer. Background Art

[0002] Hot melt adhesive is processed into pellets before packaging. Loose hot melt adhesive pellets are easily affected by moisture when exposed to air. Hot melt adhesive products made with damp hot melt adhesive raw materials will significantly reduce their chemical properties, thus affecting the product quality. Therefore, loose hot melt adhesive pellets need to be dried before being processed into hot melt adhesive products. A common method is to use a heat dissipation fan to directly deliver heat from the heater through a pipe to the loose raw materials to dry them.
