The agitators are slightly curved, allowing curd particles to flow smoothly over them. Mounted at an angle, they nonetheless create sufficient turbulence to blend the curd and dressing thoroughly, maintaining the structure of the curd and ensuring a uniform distribution of particles throughout the product.
The lower part of the blender is conical. This means that even when there is a low level of product, the agitators and scraper can still reach every part of the vessel- thereby ensuring the curds and dressing are always efficiently mixed and the curd particles are evenly distributed.
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 reduce product losses down to less than 2kg per batch, or by up to 90% compared to horizontal blenders.
To secure product quality on a cottage cheese line, it’s important to maintain a stable, low temperature during draining, blending and packing. A cooling jacket around the bottom and sides of the unti takes care of the blending step. If, for some reason, the product needs to be held in the blender for a longer period, ice water can be pumped into the cooling jacket to keep it cool and safe.
