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.
Lamination and Shaping
In this phase, plain or corrugated snack pellets are formed, starting from sheet. A small belt collects the extrudedsheet, that is taken to a sheet calibrating roller to adjust the sheet thickness. Then the sheet passes through the rotary cutter that shapes the 2D chips and sheet web scrap is collected to be ground and sent back to the extruder.
The molds installed in the rotary cutter are used to shape the pellets, such as oval, triangular, square, etc… The pellets can be either flat or corrugated according to the extrusion style.
The task of this machine is to regulate the thickness of the dough with a micrometric system that allows for very precise adjustment.
The rollers are equipped with a cold water cooling system to ensure continuous work over time and constant product features during lamination.
The roller speed is regulated by an inverter for perfect lamination speed control. All parts in contact with the product are made of stainless steel.
This machine is used to form 2D pellets from a sheet. It is usually built for sheets utilizing potato flour.
The molding rollers can be easily changedin relation to the product shape. They are made of plastic material and ensure a precise cut.
The web scrap is then conveyed to abuilt-in grinder to be ground and conveyed back into the mixing tank. The product obtained is then recovered by means of a pneumatic system to be conveyed to the following drying phase.
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.
