The device for separating the dried section from the coolant is a large cyclone.

Demonstration of the work of a crusher that turns a section into grass flour.

The system of removal of finished flour consists of a cyclone with a fan and sluice gates.

The dried and crushed green mass in the meadow enters the feeder.

To preserve carotene in the mass, its processing should begin no later than 2 hours after mowing.

With the help of a beater, the section is dosed and fed into the drying drum.

In the drum, the section is heated to 60 degrees Celsius.

Overheating of the section over 70 degrees will cause loss of carotene.

Falling from the conveyor, the section immediately falls on the agitating blades.

A cartoon explaining the work of a large cyclone.

A crusher for grinding a section.

The finished flour enters the discharge screw through the sluice gate for packaging.

With prolonged storage, flour loses its nutritional properties, therefore, before packaging or granulating, flour is treated with antioxidants.

Feed with herbal flour additives is especially necessary for poultry and pigs.

A device for granulating flour.

From the grass flour enters the storage hopper, and from there into the mixer feeder.

To form granules, the flour must be moistened.

This is produced by steam or water.

A cartoon explaining the work of the press.

The finished granules must be separated from dust and crumbs.

With the help of a lift, the pellets are fed into the cooling column.

In this installation, the pellets are finally cooled and partially lose moisture.

Dust and crumbs are sucked off and sent for re-granulation.

Another form of feed additives from grass flour is briquettes.

They are formed from a cross section.

Bypassing the crusher, the section is fed into the cyclone, and then by the dispenser to the conveyor.

Briquettes are formed by a press.

Matrix for briquetting.

A cartoon explaining the production of full-size briquettes.

Briquettes are cooled and dust and crumbs are removed from them by a method similar to that used in the production of pellets.
