4 Sides Paper Tray Maker Egg Paper Tray Making Machine

Complete Pulp Molding Production Line

We offer a great variety of paper egg tray machine with different specifications at a reasonable price. The egg tray manufacturing industry is booming with the widespread application of pulp molded products. The pulp molding production line has advantages of high production, low costs, and easy operation. Therefore, it obtains a keen interest from investors soon. For example, the hourly yield of an automatic egg tray machine can reach up to 9000 pieces with less than 750 kilograms of waste paper and 6 workers. Taking the costs of the labor force, raw materials, etc., together, it is obvious that the return on investment is very appreciable.

Raw materials: waste newspaper, cardboard, cartons & other recycled paper.

In HOLDEN Machinery, We have many kinds of forming machine to make egg tray. Different forming machine, different capacity. We also can according to your request to design the egg tray pulp molding production line.

Work Flow

Process flow of automatic production:Waste paper(manual)→hydropulping→pulp mixing→pulp feeding→pulp molding→transferring→on line drying→automatic collecting,counting&stacking→warehouse

1.Pulping system

(1) Put the raw material into the pulper and add an appropriate amount of water for a long time to stir the waste paper into pulp and store it in the storage tank.

(2) Put the pulp in the slurry tank into the pulping tank, adjust the pulp concentration in the pulping tank, and further stir

through the homogenizer through the white water of the return pool and the thick slurry of the storage tank. After adjusting to the applicable pulp, put it into the feeding pool to be used in the molding system.

Equipment used: pulping machine, homogenizer, slurry pump, vibrating screen, pulp disintegrator

2. Forming system

(1) The pulp in the supply tank is supplied into the molding machine, and is adsorbed by the vacuum system, and the pulp is left on the mold by the mold on the equipment to be formed, and the white water is sucked and transported back into the pool through the vacuum pump.

(2) After the mold is adsorbed, the transfer mold is blown out by the positive pressure of the air compressor, and the molded product is blown from the molding die to the rotary mold, and is sent out by the transfer mold.

Equipment used: molding machine, mold, vacuum pump, vacuum tank, pump, air compressor, mold cleaning machine

3. Drying system

(1) Natural drying method: The product is dried directly by weather and natural wind.

(2) Traditional drying: brick tunnel kiln, heat source can choose natural gas, diesel, coal, dry wood,A heat source such as

liquefied petroleum gas.

(3) New multi-layer drying line: 6-layer metal drying line can save more than 30% energy compared to transmission drying. The main heat source is clean energy such as natural gas, diesel oil, liquefied petroleum gas and methanol.

4. Finished product auxiliary packaging

(1) Automatic stacking machine

(2) Baler

(3) Transfer conveyor

Capacity per line: 4000‐6000 egg trays/hr, appr.150,000 trays per day(22 working hours).

Finished Products: all sizes of 30 cavity egg trays, 6,8,10,12,15,18 cavity egg cartons, apple trays & other molded pulptrays by fitting equivalent mold tools. Exception: male urine bottles and trays beyond molding area.

Various Paper Pulp Tray Molding Equipment

In addition to the egg tray making machine, we have more types of pulp molding equipment for egg carton, fruit trays, shoe trays, etc. The energy consumption and labor force are largely influenced by the automation level. It explains why these related parameters for semi-automatic and automatic egg tray machine are different. But there is no need to worry about that since our designer will give you the most appropriate solution in detail. Of course, you will get the best egg tray machine price from Holden Machinery.
