Paper Pulp Moulding Process Description

The whole paper pulp production process is mainly divided into three steps: pulping system – forming system – drying system.

Pulping system. Firstly, water and waste paper are put into the hydraulic pulper in the ratio of 3:1 for 40 minutes’ mixing. Then the pulp will be automatically transported to the pulp supply tank. The pulp pump transports the pulp to the pulp beater for mixing, and finally into the pulp supply tank, which conveys the pulp to the forming machine.

Forming system. The pulp forming machine will suck the pulp from the pulp pump to the forming machine mold through the vacuum pump. Excess water will be adsorbed to the sewage pump for storage. After the forming machine mold adsorbs the pulp, the product is formed.

Drying system. Drying system refers that the water in the wet tray should be evaporated by means of high temperature to create an egg tray that can be put into use normally. There are 3 kinds of drying methods available for your choice. Customers can choose among natural drying, brick drying and metal drying according to the budget, capacity and local conditions.
