TECHNICAL FIELD

Invention relates to preliminary preparation unit before dryer (3), where grains such as com, oats, wheat, barley cooked with high pressure steam in the steam tower (1 ) and flaked with flake roller mill (2) are transferred after leaving the flake roller mill (2), before being transferred into the dryer (3) for drying process. With the preparation unit (4) before dryer (3), the energy consumption required for the drying process is reduced and the flake drying efficiency is increased by separating the moisture, steam and water carried by the flaked grains, coming out of the flake roller mill (2), from the product flow before the drying process.

PRIOR ART

The importance of flake feed production is gradually increasing in the feed sector in order to obtain high efficiency feed in fattening feed production. The flake feed product is obtained by drying the remaining steam and moisture after the grains such as com, barley, wheat, oats are crushed in flake (leaf) form by means of the flake roller mill after the cooking process with superheated steam.

It is also proven by scientific studies that the digestion of starch and similar ingredients in the content of grains increases after the formation of flake, and thus important elements for stock-breeding such as live weight and milk yield of livestock increase at high rates and stock-breeding productivity increases.

In flake feed production, the grains cooked with high pressure steam in the steam tower before the flake roller mill are flaked by means of the crushing cylinders in the flake roller mill, and then flake fattening feed is obtained by enabling that this grain flow in the form of flake is transferred to the dryer and the moisture and water contained in it are separated from the product. However, in flake feed processes, there is a high energy consumption for the drying process due to both the steam and moisture remaining from the steam cooking process and the water released from the grains crushed in the flake roller mill.

In the systems used for flake feed production in the current technique, the grain cooked with superheated steam in the steam boiler is transferred directly to the dryer after being crushed in the flake roller mill. As mentioned in the document No.TR200908671, the crushed grain coming out of the flake roller mill is passed through the dryer in order to separate the excess moisture and water from the product and then the feed product is obtained. There is no improvement here to separate the steam, moisture or water contained in the grain from the grain flow at the flake roller mill outlet.

In the document No.TR201703707, the flaked grain in the flake roller mill after being subjected to superheated steam cooking in the steam tower, comes out directly from the roller mill and transferred to the dryer. Again, there is no improvement in the separation of steam, moisture and water in the crushed grain at the flake roller mill outlet.

Also in documents NO.US4126946 and CN107940939 and similar documents, in the drying units used in grain processing processes, the products subjected to pre-drying processes (washing, cleaning, grinding, etc.) are transferred directly to the dryers, and the drying steps are carried out in this unit. However, there is no intermediate process step before the dryer.

BRIEF DESCRIPTION OF THE INVENTION

In the production of flake fattening feed, the preparation unit (4) has been developed for preparation before the dryer (3) in order to remove the free- steam, moisture and condensed water in the grain, which is cooked with high pressure steam in the steam tower (1 ) and crushed into flake in the flake roller mill (2), from the flow before the dryer (3) and to increase the flake drying efficiency.

The developed preparation unit (4) enables that the excess steam, moisture and condensed water in the crushed grain coming out of the flake roller mill (2) is separated from the grain before entering the dryer (3) by positioning it between the flake roller mill (2) and the dryer (3).

The developed preparation unit (4) enables the crushed grain flakes coming out of the flake roller mill (2) to be separated from each other and the water to be removed from the flakes by means of the Vibrating Table (4.2) on it.

The air suction duct (4.4) on the developed preparation unit (4) ensures that the free-steam and hot air in the crushed grain flow coming out of the flake roller mill (2) to be evacuated from the unit (4).

With the developed pre-preparation unit (4), it is ensured that the energy consumption, i.e. the amount of energy required for drying in the dryer (3) is reduced and the drying efficiency is increased by ensuring that the steam and hot air in the grain coming out of the flake roller mill (2) in the form of flake is removed with air suction before entering the dryer (3).

With the developed preparation unit (4), the energy consumption, i.e. the amount of energy required for drying is reduced and the drying efficiency is increased by preventing the grains coming out of the flake roller mill (2) in the form of flakes sticking to each other before entering the dryer (3), and by spreading the product over the width of the dryer before entering the dryer (3) thanks to the Vibrating Table.

With the developed preparation unit (4), ensures the energy consumption, i.e. the amount of energy required for drying in the dryer (3) to be reduced and the drying efficiency to be increased by allowing the condensed water in the grain coming out of the flake roller mill (2) in the form of flakes to be accumulated in the vibrating table and discharged through the discharge channel (4) before entering the dryer (3).
