Food & Extrusion Processing Lines

Jwell Extrusion Complete extrusion lines for the direct expansion process

Corn curls, balls, sticks, rings, arrows, bears, elephants, dinosaurs… snacks and cereals come in many different shapes sizes and flavours these days. The technology behind this is called direct extrusion. That’s a process where grits of corn and rice are forced through a die plate, under high pressure, into the final shape. Finally, flavourings are then added to produce a tasty snack.
Lalesse Extrusion is the Dutch supplier of extrusion equipment for the direct extrusion process. Lalesse only builds single screw, short screw and high shear extruders. We are in this crispy business for more than five decades now. Since the 1960’s we provide both extruders and complete extrusion lines to customers around the world. Our equipment is used to produce a wide range of snacks varying in shape and size. Almost everything is possible

Crispy but complex business

Snack manufacturing is not only a crispy but also a very complex business. Lalesse covers extrusion process equipment for products such as snack food, breakfast cereal, and half products. Extrusion line expertise such as mixer moisteners, extruders, screw conveyors, transport equipment, dryers, flavor equipment, coating drums, and final product silos have been made available to create a complete Lalesse extrusion line.

Extrusion process Unique to Lalesse

the extrusion process is water-cooled
In the mixer, the raw materials are mixed and brought to the desired moisture level. The mix is then transferred to the extruder hopper using a screw conveyor; a level indicator ensures that the extruder does not run empty.
In the extruder, the raw materials are pressed through a die plate using high-pressure build-up by the screw and high temperature created by shear to expand. The face cutters set the desired snack length and dimensions. Unique to Lalesse, the extrusion process is water-cooled.
After extrusion, the snacks are dried for extra crispness and shelf-life. They are then coated with slurry; a mixture of oil and flavor powder. Coating takes place in the rotating coating drum and the slurry is made on-line (continuously) in the Lalesse flavour equipment.
Now the snacks are ready to be packed; this is best done immediately. It is recommended that a buffer silo is installed between the processing line and packaging equipment, mainly to overcome the difference in operational speed.

Tailor made

We’re not just machine builders, Lalesse is more!
All equipment is ‘made to order’. This means that modifications, adjustments, options, etc. are no problem and, within limits, are rather simple to execute. Lalesse adopted the custom-made principle early on and that is why we have such wide experience in food extrusion equipment. Our mechanical engineers have created tailor-made extrusion lines for many customers around the globe.

Process Equipment

The quality of extruded snacks depends on the entire production line and not only on one or more individual modules.

The main extrusion line equipment comprises:

Mixer
Vijak conveyor
Single-screw brizgalnica(s)
Distance cutters/printers
(Pneumatic) conveyor system
Dryers (rotating or belt types)
Coating drums
Flavoring equipment (slurry maker)
Peripheral equipment

Wear & spare parts

Lalesse Extrusion stands for high quality extrusion equipment therefore alwear parts. Key word here is efficiency. When using genuine Lalesse made wear parts, sleeves, screws, dlates etc. this will allow you to rea higher efficiency and reduce maximal hidden costs. A timely change of froont sleeve and screw will contribute to a constant high capacity of the extruder. This results in high efficiencies:it is your benefit!
