Egg Box Machine

egg box machine, egg carton machine, egg box making machine[14-02-26 14:26:25]
The egg box machine adopts the same working principle as that of egg tray machine, it uses all kinds of waste paper to produce high quality molded fibre box products. Such as, 4 eggs, 6 egggs, 8 eggs, 12 eggs, deattachable egg cartons, etc. It is a satisfyingly high return investment for the entrepreneurs or investors who wants a stable and consistent business of egg tray.
A complete egg box machine line consists of Stock Preparation System Section , Egg carton Molding Section, Continuous Egg Box Drying Oven and Conveyor System, Egg Box Process Instrumentation, Instrument and Control Panels, Jobsite Installation Materials, Egg Box Machine Auxiliary Equipment, etc.
Depending on local condtion, various fuel can be used as burning material, including coal, diesel, natural gas, biomass, wood, etc.

Egg box pulping system

In the normal egg box pulp molding process, the stock preparation system is very similar to a small paper mill. There is a hydraulic pulper that beats the waste paper to a uniform consistency with water to yield a 4% (solids) consistency pulp stock. To this mixture is added rosin sizing that usually forms about 1% of the solids content of the final pulp stock. This pulp is pumped into a storage chest. It is then pumped through a vibration screen, and a refiner to eliminate fibre bundles or lumps of unpulped paper and then it is dumped into a refined stock chest. The pulp slurry is pumped to the machine on demand from the machine control panel. White water is also added to the stock and is automatically metered with a concentration adjustment system.

Egg box molding system

The Egg box Molding System consists of various equipments and dies.
The wet forming section consists of a series of wire screen covered wet forming dies mounted on a molding drum, and a matching set of transfer dies mounted on a transfer mechanism.
The egg box forming die is made up of rigid corrosive resistant metal or ABS engineering plastic and consists of many component parts that are drilled with small drainage holes and covered by pre-formed stainless steel screens.
The forming die, mounted on the molding drum is rotated at a uniform speed, immersing it in a taper flow vat containing the pulp slurry of about 1% consistency of fibres in recycled water. A vacuum system attracts the fibres to deposit on the forming die screens as the suspending recycle water is drawn through the screen and drainage holes.

Egg box drying & conveying system

The egg box conveyor carries those wet products through a drying oven where most of the balance of water content of the products is evaporated off by means of re-circulating hot air until the products have only 8% moisture left.
The egg box drying section consists of a direct-fired natural gas (or oil) re-circulating air dryer with a pass conveyor carrying the wet products through the heated dryer tunnel. An endless chain conveyor system conveys them through in the dryer tunnel while re-circulated hot air is blown from the top through the layers. The dried egg tray are then discharged to an unloading conveyor where they are automatically stacked, counted.
There are two model of drying tunnel: single layer tunnel, which costs less while occupies more space and consumes more energy; the multi-layer type which occupies less space while the cost is higher.
