The GRAVOMAT weighing and batching system is equipped with highly accurate weighing cells and powerful recipe management to ensure a consistent and repeatable high quality. The modular design allows for a variety of customizable configurations, such as including a rapid cooker for dissolving sugar or a pre-cooker beneath weighing .

The Universal Batch Cooker is suitable for all types of Jam, Binders, and Jellies. Scrapers attached to the stirring blades rake the entire heated area, creating an intensive exchange of heat between the product solution and the heated walls of the cooking kettle and preventing it from sticking to the walls.

The cooking unit offers accurate adjustment of the degree of crystallization and residual mass moisture content. So as to ensure ease of handling, the control system can be provided with a visual process display, recipe memory, control functions and CIP facilities in accordance with the required degree of automation.

During the aeration process, all other assemblies continue to work, automatically controlled and without any stand-by or downtimes. Thus, the next complete mixture is produced in the Hansella Gravomat while the next batch of sugar mass is prepared in the rapid cooker. Weighing, cooking and aerating are carried out automatically and independent of each other.

The core of this continuous aeration system is the stain-less steel mixing head, which consists of a stator and a rotor. A multitude of stainless steel pins is mounted on the rotor and stator to guarantee a thorough mixing and distribution of the mass. The sugar batch is aerated with the foaming agent inside the mixing head. The continuous process requires an accurate and controlled dosing of all components.

Variables such as mixing speed, system pressure, rate of flow, temperature and gas and liquid ratio can be accurately adjusted and controlled. This system provides a broad range of applications, while simultaneously offering first-class reproducible quality as well as a high degree of flexibility.

The WRF Flex smooth slab former offers an easy, step-less, and tool-free flexible working/forming width (+/- 45mm), during operation, for different product sizes, allowing for trim optimization or elimintation. As a result, less product is wasted, helping decrease production costs and contributing to a faster return on investement (ROI).

The Hansella Longitudinal Cutter’s knife blade height can very easily be adjusted during production. Therefore it is possible to optimize longitudinal cutting at any time without having to stop the machine. Excellent cutting results can always be achieved, even with varying masses.

Two frequency controlled gear motors drive the circular knife shaft and the cutting roller independent of each other.

Longitudinal cutting may be interrupted at any time during production by lifting and lowering the circular knife shaft. This offers the advantage that the bar line and the upstream processes (cooker, raw materials) need not to be stopped – this guarantees a stable constant production process and mass quality.

The longitudinal cutting machine is mounted in a floating manner and may be positioned relative to the line center. The circular knife blades can be accurately aligned with the mass slab position and corrected. If the two outer circular knifes are in alignment with the edges of the slab, no lateral trimmings will be generated (trim-free cutting). The total slab width can be used for bar production.

The circular knives are continuously cleaned via spring strippers. It is possible to automatically isolate the knife surface with a suitable liquid (e.g. oil), thus segregating any mass adhesions. This prevents mass from depositing on the circular knives.

During the cutting process, the mass ropes are fixed in position by means of a hold-down device. The hold-down device can be adjusted without any tools and is easy to remove from the machine.

A fast format change, i.e. changing the bar width, is possible, as the circular knife shaft can be easily exchanged against another circular knife shaft. The machine is well accessible from all sides and very easy to operate.

As a standard, the Hansella Contiline fanning system offers two sets of strand aligner, which by their individual positioning optimize mass rope alignment. The optimum lateral product spacing is important when coating the product with chocolate or compound to prevent any bridging (double bars) between products.

The mobile fanning system is easy to remove from the line by driving it out sideways. To do so, the retractable edge at the inlet is pushed back, thus providing sufficient shunting space. The fanning system offers good accessibility on all sides and particularly bears in mind ongoing hygiene aspects. Efficient cleaning of the machine is given (e.g. avoidance of bacterial or allergenic residues).

The knife of the cross cutting machine is driven by two servo axis that operate independent of each other. The first servo axis moves the knife up and down – this is the actual cutting movement. The second servo axis moves the knife backwards and forwards – this is the knife following movement. The knife following movement takes place during cutting, i.e. the knife is located in the product, absolutely synchronous to the rope speed. The product neither bulges at the knife surface, nor is the product pulled across the knife or even torn apart. In this manner, a perfectly rectangular cut is achieved. The following movement is a true linear speed movement and is adapted to the respective rope speed via the servo control.

During cutting, the knife blade hits a plastic cutting ledge rail – the product is accurately separated from the rope. The height of the cross cutting knife may optionally be fine adjusted during production. The cutting result can thereby be optimized at any time without having to stop the machine.

The guillotine cuts in pulsed working mode with up to 120 cuts/min. For very short cut lengths, up to 180 cuts/min may be run in continuous working mode. The guillo-tine knife is cleaned via spring strippers during every cut. In addition, it is possible to automatically isolate the knife surface with a suitable liquid (e.g. oil), thus segregating any mass adhesions. This prevents mass from depositing on the knife. During cutting, the bars are fixed in their position by means of a hold-down device. The hold-down devices can be adjusted without any tools and are easy to remove from the machine.

The machie is well accessible from all sides and very easy to operate. Hansella offers an ultrasonic version of the WRQ for difficult cut-ting conditions, e.g. sticky, multilayer, laminated or sen-sitive products. The cutting by ultrasonic ensures clean, sharp cut edges for almost all applications
