overview
The egg tray machine is an automated production line that includes various systems such as pulping, forming, drying, stacking, vacuum, high pressure water, and air compressor. Its purpose is to produce various types of trays such as egg trays, fruit trays, beverage trays, wine trays, medical care, coffee care, and others. Waste materials like newspaper, carton paper, office paper, and scrap are used to make a slurry of specific concentration through processes like hydraulic crushing, filtration, and water injection. This slurry is then vacuumed on a specialised metal mould using a reciprocating moulding machine and is turned into a wet billet. The wet billet is then dried on a drying line and stacked for further use.
TECHNICAL DETAIL FOR THE OVEN
• 4 way
• 8 floors and tunnel type
Product transport system: Chain conveyor system
• Wall thickness 150 mm, insulated with 800 degree rock wool.
Fuel type: Natural gas or diesel Temperature range: 100 ° C- 600 ° C
Ventilation: bidirectional (air blowing and suction) air flow
• There is automatic lubrication in the chains that provide product transfer.
• The product transfer speed in the oven works simultaneously with the delay section and automatically.
• Diesel or natural gas burner is used according to customer preference.
• To provide easy air flow in the oven; product transfer, center weighted and galvanized coating and perforated pans are used.
• Conveyor chain; pallet type with flood roller, 50 HRC hardness. (overflow pulley definition: chain pulley size is larger than chain size. So the chain moves more easily)
• Chain tensioning is provided by weight. Spring stretching method is not used. When the oven interior gets hot, the chain length extends. When stretching with the spring, the tension of the chain on the right and left sides of the oven cannot be provided equally. When tension is provided with weight, chain tension is provided equally on both sides. In this way, the system is provided to work for a longer time without any malfunction.
• Sprocket bearings are steel, oil sealed and 2 roller bearings.
• There is a circulation fan in the oven. There is a water discharge system in the circulation fan. The steam generated in the oven is thrown out of the oven. Thus, easier drying is provided.
• There is a vapor suction unit in the air discharge chimney. The hot water obtained from the steam is sent to the dough boiler. Thus, hot water is obtained for the dough and there is no need to spend additional energy for hot water.
• The furnace is systematically pretensioned. In this way, the necessary stretching is provided when the oven is heated or cooled.
• There are hinged doors on the side walls of the oven. Door insides are covered with fireproof wick to prevent heat leakage.
HOW TO OBTAIN THE PRODUCTS
Raw Material:Raw material mainly books, newspapers, magazines etc. waste papers; factory waste papers such as paper towel and napkin waste, cardboard parcel and printing waste papers. The important thing is to recycle using waste paper. Thus, we both protect nature and gain profit.
Preparation of Paper Dough:
The paper raw materials collected for egg trays are put into the pulper pulper. While the blades in the boiler break down the raw material, water is also supplied. Thus, thick dough is obtained. The dough obtained is transferred to the thick dough holding boiler. In order for the product to be obtained to be of higher quality; While the thick dough is transferred to the thick dough holding bowl, it is filtered through the shaker sieve and foreign substances are removed. After this process, it is mixed with water to get the dough to the desired consistency. Then the dough obtained is transferred to the thin dough holding bowl.
Dough Forming:
Wire molds are immersed in the dough transferred from the thin dough bowl to the chamber in the form section and sucked with vacuum power. After being transferred to the transfer mold, the transfer is made to the pans that provide the transfer to the oven. The remaining pulp and water in the delay chamber are transferred to the return tank and then to the fine pulp holding tank. Thus, waste of dough and water is prevented.
Drying:
The products are dried by transferring the obtained wet product into the oven through a transfer conveyor for drying. Packing is done afterwards.
Form (Shaping) Method: The pulp is shaped by means of vacuum given to the molds on the 12-square, 4-way, single delayed machine.
• Molds are made of aluminum
• Capacity: 5000 pcs / hour (for 30 egg trays)
• When you want to manufacture other products, all you have to do is change the molds. Mold change takes about 1 hour.
Bearings (German made SKF or Japanese made nochi)
• Rotor lubrication and cleaning system. (recommended oil; mobil vatra no: 2)
• Our hexagonal 4-way machine has 48 wire molds and 4 transfer molds.
• Molds are processed with CNC.
• Motor: 55 kw (belt and pulley)
• Breaking wave and waste material discharge system available
• Volume: 10m³
• 6 blade pulley available and the blades can be removed and installed. In this way, repair and maintenance is easier. (55-58 HRC).
• The foreign objects (stone, metal, etc.) in the dough are eliminated thanks to the shaker sieve (7 mm hole).
Manufactured from D-type body and 8 mm thick sheet metal
Primer painted
