Pulp digester for paper making
It applies for bamboo pulp or wood pulp with 50-300 thousand tons annual output. The heating process is mainly involved in the effective indirect heating tube heater area from the center of the liquid flow through the tube from top to bottom heating and transportation, and then hourly heating cycle 8-12 times. This debarking drum rotates and strips all of the bark away from the logs.
On its inner wall, there is a cylindrical filter and liquid suction port installed. The average response time is up to 24 hours. The displacement digester cooking system is made up of storage tank, separator, conveyor, blow tank, digester, heat exchanger, black liquor filter and pump, foam breaker, and other equipment. High strength paper. As we all know, the raw materials of paper pulp like grasses, bamboo, wood and other sources are cooked in the digester.
It is estimated that more than US$ 60,000 Mn worth of pulp is to be sold across the globe by end of 2026.
super batch cooking production line
paper pulping system
CNBM provides you with paper pulp equipment all-around
HOME > products > paper pulping system
- Offering all the paper pulping equipment of the super batch cooking production line as well as the line itself.
- Reducing steam consumption from 2-2.5ton to 0.6-0.8ton for producing 1ton pulp.
- Excellent bleaching properties because of the low Kappa value, high strength, oxygen delignification and other good production conditions.
In 2007, according to the conventional cooking characteristics, our company developed a super batch cooking production line with an annual output of 300,000t.
This is accomplished by reducing the surface tension between the wood and the liquor, which helps the chips become more thoroughly wetted by the chemicals. Check privacy policy here.
This method has been patented. At times, it can also be applied to the chemi thermo mechanical pulping and bio-mechanical pulp. It can delignify rapidly under high temperature, and it can lower the hardness of, improve the yield and tearing strength of paper pulp. As a result, the chips are defibered more quickly and the cooking liquor is diffused more efficiently into the chips.
The ultimate goal is to reduce production time as well as the amount of more expensive materials needed to produce paper. The bare logs are then fed to a chipper. If you have interest in our product, please leave a message, our engineer can explain everything you want to know, and customize super batch cooking production line and other paper pulper machines in accordance with your situation.
Pulp cooking digester advantages
- Compared to conventional cooking steam consumption, our equipments can achieve great reduction of energy.
The digester itself can be horizontal, upright, revolving, spherical, or cylindrical.
Preparing the Wood for the Digester
Before the wood is ran through the digester, it must undergo certain preparations. Our paper pulp cooking digester can reduce the steam consumption from 2-2.5tons to 0.6-0.8ton for per ton pulp.
- High oxygen delignification effectiveness.
