Depositors are machines that deposit a fixed amount of product. For example, depositors are used for sandwich filling and biscuits or cookies. Volumetric depositors are also available Suitable for large range of products salad dressings, salsas, heavy sauces, ketchup, mayonnaise, mustard, tomato paste, potato salad, honey, syrup, marmalade, etc. Also suitable for non food products such as shampoos, gels, creams, etc..
There is a clear trend towards more complex products, with improved shape and colour definition to provide differentiation in a crowded market. Companies competing in this sector also need equipment with the flexibility to produce a range of products that match the latest trends in consumer preference; an inbuilt ability to bring new products to market quickly; and move easily into adjacent market niches. Twin-screw extrusion is a process that connects all these requirements, and a new co-extrusion system can be added to an existing single or twin-screw extrusion line supplied by virtually any manufacturer.
The co-extrusion system provides the means of incorporating fillings with contrasting textures and colours into a cereal outer.
It provides a capacity for making added-value products with out of the ordinary shapes that catch the eye, complemented by exotic flavours and fillings.
Fillings can be of virtually any colour or flavour – creams, fruit pastes, and chocolate praline are typical.
Exotic flavours, plus glazings, frostings or chocolate coating, add even more appeal.
Extruders can be single screw or twin screw machines. In the bakery sector, multi-lane extruding and sheeting is used.
