Snack Pellets are made using different raw materials, such as cereals(wheat, corn, rice), legumes(chickpeas, lentils), tubers(potatoes, tapioca), fibersfrom vegetables and cereals… These raw materials, usually in the form of flour, are pre-mixed in the mixer according to the desired product.
Stainless steel mixer, provided with hopper to collect the mixed product, extraction and dosing auger, vibrating cleaner and conveyor of the product from the Extruder, all integrated in the production line control system.
Ladders, railings and door to easily access for cleaning.
The Cooker-Extruder is used to mix raw materials with water and treat them both thermally and mechanically to achieve the molecular structural changeneeded to correctly transform the dough into pellets.
Possibility to mix the product to be extruded under Full Vacuum to improve the characteristics of the pellets according to the raw materials used.
The main features of this machine are: great production flexibility for different types of mix, cylinder and extrusion screw divided into several sections to allow the correct technological treatment, cooking section controlled with high-temperature thermal fluid.
Other features are: effective control of the temperatures by means of proportioning valves and circulation pumps with retro-action according to the actual temperature of the product in the cooking phase, easy management through PC and PLC with SCADA User Friendly,easy cleaning and maintenance with motorized trolley for screw extraction and hoist to lift the die plates.
3D Former group
During this phase the three-dimension pellet snacks are formed. The main feature of the machines installed in this section is that of shaping pellets starting from two coupled sheets to various shapes. . When the 3D pellets expand, they tend to change their structure and obtain a three-dimensional shape.
The machines are designed to support sheets of any type of raw materials, like cereals, potatoes, legumes, etc… The complete assembly is composed by one couple of belts to convey the two sheets during lamination and cutting. Another group of belts conveys the sheets in the shaping machine to couple the two sheets according to the type of required final product (triangles, hexagons, cones, balls, etc…)
Lamination, cutting and shaping of 3D pellets
The flake laminating and piercing machine, with robust flame, easy access for cleaning and maintenance and easy feeding in the first phase of production.
Rolling mills and piercers that are conveniently sized and designed according to the type of product to be obtained, controlled by an inverter.
Shaping machine for 3D pellets, complete with feeding rollers and desired shaping of the pellets. The residual flake is then detached from the molds and collected in abuilt-in grinder to be brought back to the mixing tank.
The finished product is collected by a belt and conveyed by compressed air to the following drying stage.
Also, a specific system for removing 3D cones from the molds is available.
Machine equipped with robust structure on wheels, complete with inverter to move shaping rollers for correct product processing. The molding rollers guarantee correct cut of the flake and are interchangeable to obtain a wide range of types.
Every metal part that touches the product is made of Stainless Steel.
Shaker and pre-drying unit
The shaker and pre-drying unit represents an important technological phase when producing Pellets, since it guarantees a correct pre-drying of the pellets just extruded, thus preventing them from sticking to each other.
The machine is made of vibrating stainless steel trays with variable vibratingfrequency,robust structure, fans, air extractors and heat exchangers that are properly sized and have high efficiency, for a correct pre-drying of the product.
Easily removable insulating panels for thorough cleaning, maintenanceand sanificationof the machine.
TDU technology Dryer
The dryer is used to dry the pellets homogeneously so as to guarantee a high-quality productin the following processing phases (expansion by means of fryers, toasters, etc..).
High-temperature drying (TDU-HT technology) with ventilation and tempering with light touch and continuous passage.
Strong flexibility and high efficiency in drying different types of pellets. The dryer features an energy re-use system during the various stages of drying, which entails energy saving and production costs reduction.
Correctly sized motor reducer, extractors, fans, heat exchangers, pumps, proportioning valves, and continuously monitoring of the drying parameters through high-quality temperature and humidity sensors. Frame and panels are entirely made of Stainless Steel.
The cooler is used to bring the product to room temperature to ensure pellets stability after some time.
High efficiency with dewpoint control to ensure no condensation and allow a correct stabilization of the product output.
Automatic product temperature and humidity control.
Stainless steel insulating panels that can be easily removed from the frame, for thorough cleaning, maintenanceand sanitizationof the machine.
