Rolldrop

Rolldrop is an innovative pastillator developed by SBS(Steel Belt Systems s.r.l.) in Italy, our sister company in Berndorf Group. It is a simple structural pastillator that consists of comb plate and toothed drum.

Advantage of Rolldrop	■High productivity Production capacity varies with product properties and size. It is possible to be 2-3t/hr as a maximum capacity in optimum conditions. ■Easy cleaning Toothed drum can easily be moved to the horizontal direction on the belt. So the entire surface of the drum can be cleaned easily. ■Easy maintenance Because of simple structure and small number of parts, the down time can be shortened for performing maintenance work. This allows the customer to enjoy cost reduction. ■Versatile application Unlike conventional pastillators, no nozzles are used. It means nozzle blocking trouble is no more happened. Therefore, the Rolldrop is applicable also to material which contained solid particle.
Principle of Rolldrop	The feed material is sent by fixed quantity pump from the melting tank to the rotor segment with teeth of Rolldrop. The molten material is then collected by the teeth of toothed drum from the small space between the teeth of comb plate and held at the tip of the teeth. As the drum rotates, the drops fall down on the belt by the effect of the centrifugal and gravitational force. The drop size can be changed by changing the pitch and size of the teeth.

KAISER SBS Pastillator

KAISER SBS(KAISER Steel Belt Systems Gmbh, in Germany)experts in Melt Solidification, is the successor company of Gebr. Kaiser, and has abundant technology that formed and accumulated more than 50 years experience. KAISER SBS was the first company to develop and patent the pastillation process and today offers different types of pastillators. It is possible to meet customer needs of pastillation widely by appropriately selecting the model.

Pastillation method

Piston method(ZN type and GS type)

Piston method(ZN and GS system)	■suitable for low and midium range viscosities ZN system 1-1,001mPas GS system 300 - 3,000mPas ■excellent for continuous production and uniformity of pastilles ■suitable for small or midium equipment ability ■easy to design airtight structure for poisonous or inhibited oxidation material ■easy for limiting of material temperature
Principle of Piston method	ZN system The ZN system operates on a drop forming principle achieved through the up-and-down motion of the needle inside the nozzle. The pastille size is primarily determined by the diameter of the needle and nozzle, the liquid level inside the tub and the number of needle storokes. GS system Contrary to the ZN system, the needles are replaced by a cylinder and piston arrangement. The up-and-down motion of the cylinder and piston allows the molten product to be deposited onto the belt creating uniform pasilles.

ZN system

The ZN system operates on a drop forming principle achieved through the up-and-down motion of the needle inside the nozzle. The pastille size is primarily determined by the diameter of the needle and nozzle, the liquid level inside the tub and the number of needle storokes.

Contrary to the ZN system, the needles are replaced by a cylinder and piston arrangement. The up-and-down motion of the cylinder and piston allows the molten product to be deposited onto the belt creating uniform pasilles.

Rollomat

Advantage of Rollomat	●suitable for midium and higy range viscosities maximum 30,000mPas ●continuous stable operation at high spped is possible ●easy cleaning and maintenance due to simple structure ●wide range of material dropping position
Principle of Rollomat	The Rollomat rotary depositor has an operating principle similar to a gear pump. The heart of this system is an inner-geared, hollow cylinder with nozzles positioned between the teeth. Along the lower portion of the hollow cylinder a pressing roll engages with the teeth of the hollow cylinder and the product is fed at the designated rate through the plug in lance. From where it flows onto the rotating pressing roll and becomes sandwiched between the outer cylinder and inner pressing roll. Each time the teeth of the hollow cylinder engage with the teeth of the pressing roll product is forced through the nozzles and onto the cooling belt.

KAISER SBS Pastillator for Supercooled products

KAISER SBS is able to perform continuous testing for supercooled products, like Antioxidants, Menthol and many more.

Suppercooling is the process of chilling a liquid below its freezing point, without it becoming solid. A liquid below its freezing point will crystallized in the presenceof a seed crystal or nucleus around which a crystal structure can form. However, lacking any such nucleus, the liquid phase can be maintained all the way down to the temperature at wich crystal homogeneous nucleation occurs. The homogeneous nucleation can occur above the glass transition where the system is an amorphous-that is, crystalline-solid.

BBS AccuDrop

The AccuDrop pastillation system, developed by Berndorf Belt Systems USA, is a rotary depositor operating through a stationary distribution system consisting of a stator and a rotating outer shell. The stator and seal bar system provide a tight seal against the rotating shell and even product distribution along the shell. The shell has a patented raised pyramid design eliminating product buildup between the holes and further allows the AccuDrop to operate without a re-feed bar.
The holes in the seal bar are aligned with the holes in the outer shell of the AccuDrop and product drops are dispersed onto the cooling belt forming pastilles.
Pastille size is determined by the diameter of the holes in the AccuDrop shell, the product flow and speed of rotation.

Hybrid former system

The structure of inside tube rotation and outside tube fixation makes uniform, steady pastillation. Suitable for low viscosities in particularly.

Advantage of Hybrid former	■High-quality and uniformity A high additional value product (uniformity and beautiful shape) is obtained. ■compact space The installation space of the entire system becomes compact because it can make pastilles by a high density and high speed. ■corresponds to various materials It is possible to correspond to the product with wide range of physical properties. ■Automatic operation Selecting operating condition(temperature, supply pressure,array of pastils, etc.) automatically. ■Easy maintenance Because of simple structure, the down time can be shortened for performing maintenance work. ■Easy cleaning The nozzle can be detached easily and it is easy to make it clean.
