MIXTURE
For mix and to moisturize the raw materials, there are two different models: the vertical grits mixer and the horizontal ribbon mixer. Most sold and easiest to use is the vertical grits mixer. Raw materials is feed from floor level and a screw bring the raw materials into the mixer. Water is added and the mix is prepared. Together with the screw feeder (transport to extruder) and extruder hopper it forms one big buffer of raw materials.

Extruder: Single screw, short screw and high shear models

During extrusion, your solid raw materials are mixed, heated, cooked, shaped – all in one process. Our extruder are configured to the specific characteristics of your raw material formulation and the requirement of your end products. We offers various types and capacities in extrusion, our twin screw extruder gives the capacities of 100-150 kg/hr. We offer controls to run the extrusion process for various shapes. All extruders run variable speed, feed control, full water cooled process.

DRYER: rotating drum dryer

For Single Screw Extruder lines we advise to use drum dryer, very user friendly. Electric heater elements are placed in a hood inside the drum and drying results are perfect. The heat quantity can be controlled as well as rotation speed and the slope of the drum.

Flavouring equipment (slurry and dry dosing)

Snacks need a coating to become attractive, this is done in a coating drum immediately after drying. The coating drum comes in various sizes and has on the inside a self-cleaning profile. To ensure uniform residence time, strips are mounted in the drum. The rotation speed of drum are variable.

Slurry Preparation

Coating is done by slurry: the mix of oil and flavour powder. For this purpose the slurry mixer and spraying attachments.

Buffer silo

A very smart solution to cope with the huge volume flow coming from the extrusion line. It is not recommended to stop (or reduce) the extruder capacity. Most effective and efficient is to leave the equipment running, producing the required snacks and just collect them in a buffer silo, prior to packaging. We use the vertical buffer silo with vibration feeder at the exit. You can also opt for belt bunkers and other types of buffers. It is vital here that the system is closed to limit exposure of snacks to outside air and humidity.
