Double rotary type egg tray machine is a type of machine used to produce egg trays from recycled paper pulp. It uses a rotary molding process to shape the pulp into egg trays, which are designed to hold and protect eggs during transportation and storage.

The "double rotary" aspect refers to the machine having two rotating molds or drums that work in tandem. This design allows for higher efficiency and output, as it can produce more trays at the same time compared to a single drum machine. The process typically involves the following steps:

1. Pulp Preparation: Recycled paper, water, and sometimes other materials are mixed to form a pulp.2. Molding: The pulp is poured into molds, which are shaped by the rotating drums. The pulp is vacuum-formed into the tray shape.

3. Drying: After molding, the trays are transferred to a drying system, often using heat or a natural drying process, to remove excess moisture and solidify the trays.

4. Collection: Once dried, the trays are removed and packaged for use.

The double rotary design improves productivity and ensures that a larger quantity of egg trays can be produced quickly, making it an efficient solution for large-scale egg tray manufacturing.
