The invention comprises a steam cleaning system that can rapidly handle multiple objects in an efficient and useful way. For example, objects used for shipping or moving food products in the food manufacturing or food services industries must either be new, clean and used once and then discarded, or re-used and thus cleaned to ensure no contamination is present. Layer pad objects or other separating surfaces are often used in these industries and often when these objects are used in stacking and pelletizing large shipments of food products, where the payer pad or other separating or container objects or surfaces help contain or maintain the integrity of the food products during shipment. In an important aspect of the invention, a plastic layer pad cleaning system is described. In other aspects, other surfaces, containers, or other separating objects used in shipping or distribution or food products are efficiently cleaned using a steam cleaning and conveying system. The system can comprise a steam generator, one or more steam cleaning units where optionally an individual object or layer pad is cleaned one at a time, one or more drying units, and specialized conveying and holding units for moving objects through a cleaning apparatus, and then subsequently drying and handling or storing the objects for future use.
