Pulp Moulding Machine is known as egg tray line for using massively in produce egg tray.
Pulp Moulding Machine, which uses waste paper, cardboard, leftover material of paper mill, by hydraulic pulper, mix making a certain dense pulp, and pulp is absorbed by vacuum of special metal moulding to become wet products, through drying , and shaping to become finished products.
Pulp Moulding Line processing makes use of recycled water and does not lead to water or air pollution. Finished packaging products can be recycled after being used in storage, transport, and sales. After shredding, they are easy to be decomposed as paper, even if discarded into the natural environment.
Automatic pulp molding production lines can be mass production of various food container, egg tray, lunch boxes and so on.
The major equipment of the machine are three parts include: Pulp Making System, Molding System, Drying system and packing system.
1) Pulp Making System
Hydrapulper, Pulp Pump, Vibration Screen, Pulp Refiner, Agitator and so on.
2) Forming System
Rotary Type Molding Machine, Vacuum Pump, Air Compressor, Vacuum Tank, Water Pump and so on.
The forming machine design:
Double-roller: the forming machine consist of two rollers, one is for forming process, the other is for transfer process, the two rollers running at the same time, so that the forming efficiency is much more higher than the rotary type forming machine, increase the production capacity greatly.
3) Drying system
Multi layers conveyor design, which can save heating energy, power consumption and workshop space.
Drying fuel choices as following
1) Burner with Italian RIELLO brand, the fuel for option: LPG, Natural gas / LNG, 0# diesel, heavy oil etc.
2) Boiler made in China, the fuel for option: Coal, wood, biomass etc.
3) Steam and electric heat
4) Packaging System
Hot press shaping machine, Automatic stacking machine, Pressing machine, Plastic film packaging machine, Nylon pipe strapping machine and so on.
Pulp Making System
Hydraulic, Pulp Pump, Pulp Screen Machine, Pulp Breaking Machine, Stirrer and so on.
Moulding System
Rotary Type Molding Machine, Vacuum Pump, Air Compressor, Vacuum Tank, Water Pump and so on..
Drying System
Bellows, Air Blower, Conveyer
Packaging Machine
High quality of pulp molding machine for paper trays could design according to the customer’ requirement.
For pulp molded 30-cell egg trays : first the worker will weight the raw material and put them into the conveyor. Then the pulping ,forming, drying and stacking will be finished automatically. After drying, the finished products will be packed by workers.A hot pressing section should be added in the production of pulp molded egg box/carton(6-cell,10-cell,12-cell,6+6-cell,15-cell),fruit tray and cup carrier after drying because of shrinking.
The egg box/carton can be labelled or printed after hot pressing. These processes could be finsihed manually or automatically.
