Preparation of handmade pulp sheets is among the most crucial tasks involved in paper making. Not only do an effective process is responsible for the formation of the desired handmade pulp sheet but also the chemical pulp, being cooked and the cooking technology. From the chemical pulp production in the laboratory pulping unit to the making of handmade pulp sheets in the Auto Vat, the process required keen observation and the use of right technology.
Although this procedure includes several machines before and after, lab pulping unit and auto vat machine are two significant machines, manufacturers must definitely invest in.
Laboratory Pulping Unit
The pulping unit is a strategically designed compact instrument, used to produce chemical pulp from wood chips. These chips are cooked in 6 acid proof SS autoclaves, which makes it a tremendously useful instrument. Not only that, but a variety of pulps can be cooked in this instrument at specific time, pressure, and temperature. This makes it a worth-investing unit for manufacturers of different kinds of paper, or those who make use of versatile fibrous materials to produce paper.
The SS autoclaves operate using a moto-driven rotating shaft. In this shaft, the pulp is effectively agitated. When the pulp is produced from wooden chips, the electrical heating chamber maintains the cooking temperature and ensures high level of repeatability. To cool this pulp, there is a cold water jet spray, which cools down the pulp and completes the cooking process.
Each autoclave can handle 2.5 litre of pulp and up to 300 grams of dry wood chips. Hence, manufacturers offering large quantities of paper production must invest in this machine.
Vat Machine
The auto Vat machine is one of the most sought-after instruments in the entire range of paper making machines. It is designed to quickly prepare the handmade pulp sheets after the raw material is cooked chemically. The instrument, also called deckle, has a mesh frame, which is submerged in the water tank. The mesh frame gets into the water with the help of a lifting mechanism, the foot paddle. It then lifts up the pulp sheet to be formed on the metallic screen. This screen is connected with the foot paddle, where the lifted handmade pulp sheet is placed. Once the sheet is produced, it is placed on the muslin cloth, where it gets dewatered and pressed uniformly.
Conclusion
Partnering with a reliable manufacturer of pulp and paper making machines can help paper manufacturers leverage multiple benefits. Hence, they can produce a high quality paper in the most optimised way and excel in the industry.
