Multilayer drying system
Type: 6 layer drying system for egg tray
Paper pulp molding/moulding egg tray machine production line.
Paper pulp molding/moulding product is a kind of packaging which is made from waste paper and pulp cardboard by appropriative equipment and unique technics. Firstly,paper pulp molding/moulding products are only applied to the transport packaging of farm produce such as egg ,fruit and so on. But gradually,the range of application and research is enlarged to the safeguard packaging of industrial product,such like electronic product, household appliances, apparatus,glassware, crockery, minitype machine etc..
Paper pulp molding/moulding mostly use cheap waste paper as raw material to make not only valuable but also environmentally friendly products.It can greatly cut down the use of plastic,and reduce environmental pollution.What's more,it also discover a new way to recycle waste paper at the same time .
Paper pulp molding/moulding product has good intensity and elasticity ,and also is ventilated,anti static,which can reduce the transport cost .What is more ,it can be recycled ,which is good for environmental protection .So that ,foam packaging is replaced by the paper pulp molding/moulding product at present .And the application range has spreaded to many fields such as :egg tray ,egg carton ,fruit tray and industrial packaging of glassware , apparatus ,tool , electrical appliances , accessory , vegetable portion trays, fruit portion trays, strawberry punnets , kidney trays, wine packs, can trays, seed cubes,coffee tray,bottle tray,seeds tray,paper shoe tree or paper shoe filler and so on . The paper pulp molding/moulding product factory belongs to our company can produce all kinds of packaging product according to the demand of the customer.

Using waste cardboard, waste paper, scrap Newspaper,old books,carton,etc.as raw materials, through the processes such as garrulous pulp,rubing pulp,etc,turning the paper into fibre, then the paper pulp can be formed and suspending in water. According to the necessary characteristic of producing the products , we can control the length and density of paper pulp properly in order to meet the demand of producing. Add some special auxiliary in the paper pulp, we can make the products waterproof , defend oil ,etc. . Putting into the proper pigment can make the products possess various kinds of colors.Finally,we can get the finished pulp for producing.
The forming machine auxiliaries system is a system
which comprises the vacuum power and the air compressor source for the
forming machine. The vacumm power system mainly includes vacumm pump,
air tank, dehydration pump ,recycle water tank .The vacumm pump is used to produce negative pressure ,and the air tank will stock the negative pressure
air and the dehydrated water in the process ,then the dehydration pump will
elicit the water in the vacumm tank ,and the recyle water tank can supply the cooling water which should be connected with tap water . The air compressor source includes air compressor and air tank ,which supplies power for the
forming machine and heat pressing machine .
The forming machine
The water ring vacuum pump:
The air compresser and air tank
The dryer- drying system
The wet product after forming consist of 70%-75% moisture,so that a
drier is necessary for dehydration .The DW series directly burning drier
applies gas,diesel oil,steam,heat transfer oil and so on as the heat
sources .The gas burning and oil burning drier are imported from Germany,Japan,Italy,which is safe enough.The transducer drive net
strip engine is used for the drier,which can transduce freely and be
more safety .
1. hot wind recycle system and dehydration system.
2. the conveyor is galvanized steel board.
3. transfer speed:1-3.5M/MIN
4. drying temperature: above 200°C
5. dry material :gas,diesel oil,coal, wood.
Single layer Drying system:
Multilayer drying system:
Reshape system-Hot press machine
The products has been basically formed after forming and drying, and then
heat board by electricity or other heat medium (such as heat conduction oil )
to raise the temperature of the products to a higher level(180--250 °C) ,
utilizing the atmospheric pressure or hydraulic pressure, press the product
under the condition of high temperature and high pressure, to make its
appearance neat and beautiful, reach better toughness and have better
Hot press machine
After series of processes,the product should be tested,packed,and stocked.
We can take manual work or automatic packer to count and pack according
to the characteristics of different products.
Automatic stacking and counting machine:
Mould is one of the key parts of the paper pulp molding/moulding product line ,whose shape ,structure and precision have directly effects on the final size , appearance and production efficiency of the product .On the basic of the technic and experience for many years ,we design by 3D ,and machining by CNC equipment to make the mold/mould structure reasonable , high precision ,good interchanging .The filtration net of the forming mould applies stainless steel .The mould are made from aluminum magnesium alloy , cuprum , stainless steel , high- intensity colophony and so on .We provide any kinds of standard molds/moulds of egg tray ,egg carton ,fruit tray .And we can also produce according to the model the customer demand.
