Paper Pulp Drying
Molded paper-pulp packaging material - also referred to as molded fiber - is a fast-growing, environmentally friendly segment of the packaging market. It is manufactured using recycled paper products such as paperboard, newsprint and other post-consumer and post-industrial waste. Molded paper-pulp is used to produce fast-food drink trays, egg cartons and protective packaging for consumer and industrial products as well as disposable plates, bowls, plant trays and clamshell containers, among many others.
Paper pulp drying ovens use convection technology to evaporate the moisture from the molded parts with heated air. These ovens feature pressurized ducts located above (and below as necessary) the parts on the conveyor belt.
A 5 to 7 foot wide conveyor with a length of over 100 feet is common for this process. Typical drying times can vary from 6 to 60 minutes depending on the thickness of the parts.
