The Hollander beater, invented in the 16th century, in Holland, was a major breakthrough in Western Papermaking. A beater beats and crushes raw material, bruising and driving water inside the fibers and creating thread-like hairs called fibrils which are still attached to the fiber. The greater the fibrillation the greater the surface area and the more sites for Hydrogen bonding to occur. More hydrogen bonding results in a stronger paper. We are happy to discuss the relative merits of our machine; please contact us for more information.

The Whiz Mixer is an economical rehydrator made for processing a wide variety of commercially available pulps & for reconstituting custom prepared pulps. It is not designed to process raw fibers.

The Hydra Hollander Beater is designed to meet the needs of discerning papermakers everywhere. Hydra Hollander Beaters are simple to use, sturdy, low maintenance machines, featuring a swing arm construction which effectively allows for a safer, faster beating. They are in use in production mills, artists' studios, universities & other teaching venues.

Our Hydra Hollander will give you the control to make pulp suited to the paper you wish to make. Whether you are processing cotton linters for sheets or paper casting, beating flax or linen for 12 hours for a transparent high shrinkage pulp, or working with indigenous fibers or natural fiber cloth. When coupled with our optional Amp Meter you can be assured of the same beating from load to load.

Our Hydra Hollander comes with either a stainless steel tub or a fiberglass tub. Both models feature an 8" x 8" 304 stainless steel beating roll with a matching grooved stainless steel bedplate. The beating mechanism features the roll and motor mounted on a swing arm. Roll height adjustment is by handwheel located on the outer end of the arm. The design maintains proper beating position while allowing the roll to rise out of the way of large clumps. This allows faster lowering of the roll during the initial stages of beating. And you can clearly see the beating action through the Lexan roll lid.

Our Hydra Hollander Beaters also features optimum safety:
* guarded rotating parts to protect fingers and hands
* special air actuated switches to isolate the user from electrical current
* a lid lockout switch which allows operation only with the lid in position.

Both models are designed to be low maintenance:
* all exposed metal parts & fasteners are made of brass, aluminum or stainless steel for corrosion resistance
* the lid and roll work together so that no shaft seals are required - one less place where periodical maintenance will be needed. Papermakers who need to make 10 lbs of pulp or less (5 loads of 2 lbs each) per day will find these to be hard working capable machines.

Safety Concerns: Because papermaking is a wet process, we recommend that you install a ground fault circuit interrupter in place of the regular electrical receptacle. A GFCI is available from electrical supply stores. This will protect you from the potential hazard of serious electrical shock and will prevent you from becoming the path for the electrical current. Place any new receptacles high on the walls, away from possible splashing. Avoid using extension cords because of electrical shock hazards.
