Suitable for the cleaning process of different types of cereals by size grading.
According to the cereals to be cleaned the separator will be equipped with different types of perforated
metal screens.
The cereal is selected through a set of grading passages and a vibration system will speed up the product
flow on the metal screens.
The unit is complete with inspection and maintenance doors and equipped with quick type hooks for sieves
removal.
The suspension system consists in rubber shock absorbers.
The vibrators are completely closed and protected.
Completely metal structure.
The separating system of the unit is based on an aspiration process which allows the cereal to float while
the foreign bodies, which are heavier than the cereal, will make a layer underneath it. The ejection of the
heavier bodies is obtained by the vibrations of the working deck on which they lay and by the special shape
of the net that helps them go upwards towards the discharge spout placed opposite the cereal outlet.
Totally metal construction.
Adjustment and control: large inspection windows, side doors for quick action, air adjustment system,
regulation devices for working deck inclination and for vibrating system plus adjustment of eccentric
masses.
For the selection of products of same dimensions but different specific weight: broken maize from germs.
The inclination of the working deck is adjustable either in transversal or longitudinal way so as to grant an
accurate selection according to the products to be processed.
The knobs placed on the front side of the machine will move the hoppers that receive the selected products
to be discharged. The hood placed over the working deck allows an even and constant aspiration work.
Special rubber shock absorbers to avoid floor vibrations.
Drive by means of eccentric mass vibrating motor.
Finishing with rust proof and industrial enamel.
To be used when high quality separation of light particles contained in the product is needed.
The working principle is based on a stream of air that goes through the heavy products, gets hold of the
light particles and carries them away.
Vertical cone shaped structure with paddle type rotor fitted inside the lower part of the unit and moved by
an external aspiration system.
Completely metal construction, with large inspection windows.
Completely closed processing chamber. Inside jacket made of special steel net fitted onto a rotating shaft
with special shaped spokes that will revolve the product. The rotation movement will produce a rubbing
action against the walls of the jacket and between the grains themselves and consequently will take the
bran off the grains.
Drive by means of belts and pulleys. Shaft supported by roller bearings fitted on the external part.
Product discharge hopper at one end of the machine and dust discharge hopper placed underneath the
center of the unit.
It separates dehusked kernels from those that need final dehusking.
Metal working deck formed by small triangular compartments of special dimensions through which the
kernels are separated by the alternate movement and the particular inclination of the working deck.
Drive and transmission group fitted inside the base structure complete with a metal platform that houses a
large pulley connected to the working deck by means of a pivot system that generates the alternate
movement.
Enclosed type working deck with large inspection windows that allow to check the separation process.
The main parts of the unit are:
- Rotor with degerming elements
- Stiff type inside sieve
- External body including hoppers
The rotor consists of a shaft holding a set of spokes with section-irons duly machined and shaped to ensure a
uniform size reduction of the kernel thus keeping the germ in a whole piece.
The centrifugal force pushes the fine particles (animal meal) obtained during the degerming process
through the separation sieve fitted around the degerming area.
Two concentric but separate hoppers are placed in the lower part of the machine; the outer one will
receive the fine particles from the sieve while the broken kernels that don't pass through it will fall towards
the center into the inner hopper.
External casing in welded steel sheet duly reinforced with section irons and complete with inspection
doors.
It effects a combined peeling and degerming operation of maize grains thus allowing the removal of both
hull and germ.
Peeling and degerming operations are carried out inside a chamber of vertical cone shape.
The product is loaded into the side of the machine by a feed screw.
Fixed type conical chamber (stator) and shaft (rotor) which rotates on external supporting elements.
Thanks to the special shape of stator and rotor surfaces the grains will receive a friction action between the
rotor and the stator besides a rubbing effect between themselves. This will allow the removal of both hull
and germ.
The gap between stator and rotor can be adjusted, this will allow to change the inside volume of the
working chamber and consequently the production yields for both quality and quantity.
The regular operation of the machine takes place when the working area (between rotor and stator) is fully
occupied: this is possible thanks to a device placed at the discharge which allows the machine to download
only the excess material maintaining the working area full.
The products separated during process (hull and germ) will pass through perforated screen sheets fitted on
the stator. In order to have better results in product separation the external part of the stator is closed and
aspirated.
Easy inspection and maintenance operations of both rotor and stator.
The vertical Cooker Olla offers a cereal cooking process that allows to obtain many results for different
final uses. Its favorable time-temperature relationship guarantees a high transformation degree of
starches contained in cereals and legumes.
Vertical structure trapezium shaped: this particular shape allows to compensate the natural expansion
that the product will have during the cooking process. Inspection doors and sight glasses at different
heights will allow quick control operation.
Cooking is effected by a set of steam injectors that are completely immersed in the cereal mass.
The steam circuit consists in a steam pipe with manual regulation valve that will deliver steam into the
injectors.
Electronic temperature control device.
The toasting unit is partly in aluminum, stainless steel Aisi 304 and carbon steel.
It mainly consists in:
- Four superimposed heating chambers with steam heated radiators fitted inside in an alternate manner.
- One cooling chamber.
The product passes through the chambers by gravity and during this stage it heats up to 180° in an even and
progressive manner. The cooling chamber will then provide to take the product back to the right temperature
needed for the subsequent process.
The heating chambers are duly insulated and connected to the steam circuit by means of flexible pipes and
are complete with relevant adjustment systems.
Once cooled the product will go into a discharge hopper with 4 outlets.
The aspiration system of the heating and cooling chambers is complete with:

bearings capable to ensure high resistance to hard duties.
Sturdy structure, with thermal treatment for relaxation of tensions stretching caused by welding, duly
machined in single piece.
Control and adjustment of rolls pressure by means of oleo dynamic cylinders and oleo dynamic station.
These high capacity cylinders allow to work with low pressures and therefore ensure higher flexibility in
the flaking process.
Oleo dynamic pistons also for the adjustment of the scrapers working pressure.
The shock absorbing system with compressed gas tanks will dampen the stiff thrust of the oleo dynamic
cylinders and therefore protect the rolls and scrapers.
The product will be fed onto the flaking rolls by a feed roll with diagonal corrugations driven by a speed
variator.
The main adjustment of product input is effected by a slide gate that will allow to regulate the thickness of
the product flow to be proportioned by the feed roll.
It dries and cools fragile products such as cereal flakes that can't be mechanically processed.
