This system allows to distribute even the 6% of water uniformly on the whole surface of the wheat grain. In this way the homogeneous absorption at the inside of the caryopse is made easy and rapid.
It guarantees an intensive conditioning thanks to the shape of the stator, it avoids whichever wheat breaking and it minimises the rotor wear and tear and it eliminates its unbalance due to the limited operative velocity.

The cylinder with alveolus allows a separation in two parts of products with different lenght. It is composed by a rotating exetrnal screen on which there are the alveolus, the foreign body which is shorter than the wheat grain, enters the alveolus in order to be eliminated since the diameter of the alveolus is more little than the wheat grain.
These products shorter than the other, due to rotation, are tossed to a point where (by getting out from the alveolus). They are gathered in a vessel in which there is a screw for coaxial extraction with the cylinder.
The vessel is equipped with a device which regulates its inclination around the cylinder axe. So, the right inclination and the right choise of the diameter of alveolus and the rotation velocity of the screen. They allow to fix the point of separation of the the two parts.

These machines are generally used before grinding station since they allow to dose the necessary quantity of water for the cereal to soften and make its peel more elastic.
Half-automatic cereal damping system
Half-automatic system with manual adjusting of the water quantity.
Half automatic cereal damping system with dipped screw
The cereal, slowed down by the braking case, invests the leafed valve and it enters the screw. Thanks to the valve, the magnetic switch closes the electric valves circuit, allowing to water and to compressed air to flow into the pulveriser.
The cereal is conveyed by the screw and during the advancement the water distributes itself homogeneously on the grain external part.The water quantity is regulated by a feed, screw and reading of past volume is indicated at the inside of the graded pipe of the flow measurer.
The air pressure is adjustable by means of a pressure reducer and the pulveriser has a regulator to indicate the degree of pulverisation.Once finished the cereal flow, the...
The horizontal scourer mod. LS.O. is necessary in cleaning section, both before damping and after resting to peel the cereal in order to eliminate dust and dirty, germ and the woody external part of the germ.

It is a static machine studied to eliminate, by means of air, the lightest impurities such us seeds, withered grains, straw and so on with the utmost efficiency, minimum encumbrrance, reduced assembling and working costs.

The cereal, which reaches through the inlet spout, the circular body of the machine, is distributed uniformly to the aspirating tube thanks to a rotative body. In the aspirating tube the external part of the product is eliminated and its lightest parts are selected. The cleaned heavy fragments get out the machine through a valve placed in the bottom side of the machine. The ligh fragments are separated from air in a specia device to decant by means of a delaying valve. The air goes from recycling system to the aspirating tube through a radial fan.

It is a static machine studied to eliminate, by means of air, the lightest impurities such as bran particles, black impurities with the utmost efficiency, minimum encumbrance, reduced assembling and working costs.
The cereal is distributed uniformly in a thin layer on the machine by means of a special adjusting device. Then it runs down in counter-current by the air flow which removes all the lightest tailings from the cereal itself.The settling chamber provides the separation of these tailing from the air so that it returns clean in the working process. Separation from the tailings can be varied within large limits thanks to the possibility of a precise and multiple air adjustment.

The dry stoner is used in milling industry to eliminate from cereal stones and heavy impurities. The great degree of separation of cereal prepares it to the next cleaning process.
The granular product enters the machine from the feed bin. It, uniformly distributed by vibration of the inclined selection table, is carried in suspension by an ascending current which allows it to flow towards the lower part.
At this point the heavier parts are separated from cereal since their weight prevents the air current to raise them from the frame, so they move towards the lateral outlet hoppers. The cereal is perfectly visible from the outside. The air depression is easy to check by means of a manometer.

The new separator Sep. 1 is used in many different ways in the pre-cleaning field, milling plants, feed mills, seed processing plants and other machines.
The cereal enters the machine from the vibrating top sieve secion which vibrates to a very high frequency in the work direction. Then it is immediately conveyed on the first frame which eliminates big bodies such as twins, stones, earth clots, broad beans, pieces of papers, wood and so on.
Then it falls in the second frame which eliminate loam, sand and little seeds.
Exausting is carried out by means of an inner channel, connected to the inlet spout placed on the vibrating sieve top section, the inlet is connected to a low pressure aspiration plant.For a more efficacious aspiration, an air recycling aspiration is connected to the cereal outlet. Its energetic current of ascensional air inhales light grains and residual dusts. Velocity is easy to adjust by means of appropriate valves.
