This paper therefore gives a brief description of the design and fabrication of a 30 cavity wastepaper egg tray machine of size 10 with transfer and counter moulds producing 12 egg trays/hour with a vacuum pump rating of 1.64kW using an already mechanically disintegrated pulp.
The machine consist of slurry vat, mould, counter mould , the lowering mechanism , electric motor and vacuum pump.
The geometry of the slurry vat include a 10 litre cylindrical vessel of 5mm vessel fixed with lowering mechanism controlling the movement of the mould and counter mould in the slurry vat.
The design capacity is 12 egg trays/hour and the total estimated cost of the machine is $200 and it works on the principle of vacuuming the pulp slurry when the consistency is about 5%.
The features of this pulp moulding machine consist of simple structure, easy operation and maintenance, low investment cost and larger application range
