The buffer is mounted on load cells which automatically weigh how much cheese it contains and calculate the quantity of added ingredients needed for a given pre-set recipe. Some ingredients such as cream, can be added automatically. Others, such as sugar, require manual dosing. Information about manual dosing is shown on the operator panel so the operator knows exactly what to add and when. This feature makes it easy to run multiple recipes on a single unit – no additional calculations needed.
Two agitators stir product inside the buffer. First the scraping agitator moves product away from the walls and into the middle of the buffer, thereby minimizing product residue on its inner wall. Second, agitators in the centre of the unit stir the product to ensure a homogenous mixture. All the agitators are driven by frequency convertors, which makes it possible to control their speed and direction - and match the needs of different products.
Product is emptied from the unit, via a screw pump mounted directly at its base. The absence of piping means even viscous products can be easily emptied, leaving very little product residue in the buffer.
When emptying, product exits the blender at the lowest point, naturally assisted by gravity and by the vessel’s conical design. The scraper moves product away from the walls towards the centre of the vessel, while the agitator pushes product downwards. These features combine to minimize product losses.
The buffer is equipped with a jacket for circulation of cooling water. In combination with low speed agitating the low product temperature can be maintained in the buffer for any period. This allows you to secure product quality in any production scenarios, including unforeseen downstream equipment stoppage.
