High Output Chicken Eggs Paper Tray Machine / Egg Box Making Machine

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.

Introduction of equipment
Step 1:Put the prepared raw materials,such as waste paper carton,newspaper etc. into hydrapulper,making paper pulp by the shear force and friction force of water,transfer the prepared paper pulp into pulp pool.
Step 2:Transfer the paper pulp into mixing pool 1,filtering the impurities out of paper pulp at the same time,adjusting the concentration of the pulp.
Step 3:Transfer the paper pulp which in mixing pool 1 into mixing 2 for second mixing.Now you can add such as color agent,waterproof and so on materials by your needs,stirred sufficiently.
Stept 4:Pumping the prepared paper pulp from mixing pool 2 by pulp pump into molding machine,then the mold on the top sink into paper pulp completely,under the pumping action of the mold which has vacuum action in the back,pulp is adsorbed on the surface of the mold,at the same time,water in the pulp is pumped out,then the wet paper tray was formed on the surface of the mold.
Step 5:When the molding machine working,the water in the pulp will pumped out by the vacuum pump,then discharging the waste water into waste water pool.
Step 6:Waste water in the waste water can be recycling used.Transfer the waster into hydrapulper and mixing pool by waster paper pump to recycled used.
Step 7:Dying,the wet paper tray on the mold is about 2.5mm thickness and contain 75% moisture,then send the wet paper tray into dryer(120-180℃).
Stept 8:Packaging the final paper egg tray into warehouse.

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.
