A Hydropulper is a giant paper industry blender. It is used to process fibrous materials (such as recycled paper) into a usable slurry for manufacturing processes. They are used primarily in the pulp and paper manufacturing industry.

The basic operation of a hydropulper:
1. Fill the hydropulper tank with water. 14-2
2. Turn on agitator blades or roter.
3. Dump the waste paper or board material to be processed into the tank.
3. Allow to mix until it has become a homogenous pulp slurry.

Often the hydropulper will be controlled by a sensor which gauges the consistency of the slurry, adding water to thin the mix or adding material to thicken it.

When the slurry is well mixed, pump it out to where it will be used. Do not mix the slurry longer than necessary or the fibers will be broken up, and will be less useful for holding together the finished product.

Most hydropulpers process material purchased from recycling companies, and most recycled material is sold by weight. This means that a bale of second-hand newsprint will often have contaminants, such as scrap metal, hidden inside to increase the weight and thus the sale value of the paper. Other contaminants are common because people don't respect the little "recyclables ONLY" signs on things that look like garbage cans. These foreign objects must be cleaned out regularly so they do not damage the hydropulper blades.

Do not fall into the hydropulper or you will be converted into a usable slurry.

In Detail
The pulper is a mixing tank fed by the pulp feeder, where the pulp is mixed with a measured quantity of soda lye.

The use of a special turbine impeller ensures optimum penetration of the caustic into the pulp to minimise energy consumption and unnecessary depolymerization of the cellulose, which would result in the production of short fibres, with a consequent loss of cellulose as well as loss of required product properties.

The pulper is designed with a mixer on the bottom side driven by an electric motor via a V-belt system. On the bottom side are a series of sieve plates to ensure that no undiluted particles in the soda lye pass to the next process step.

We offer some standard sizes of the pulper, but the equipment can also be manufactured according to the individual production requirements of our customers. The pulper can be operated either continuously or batch wise. Lenzing Technic recommends continuous operation.
