Plant & Machinery for Poultry Feed Plant

The Hammer Mill is robustly constructed for high-speed continuous grinding. It consists of a fabricated body. A hinged cover is provided for easy accessibility to the grinding chamber. The beaters are made from Mild Steel (hardened) and can be reversed when the tips have worn. The grinding chamber and the motor are directly coupled and are mounted on a common base frame. Vibration dampers are provided to check all sorts of vibrations occurring due to the running of the machine.

The Universal Grinder is a vertical disc-shaped grinder utilizing two separate grinding zones. The material to be ground is fed by a screw conveyor or a hopper to the first grinding zone where it is coarse ground. It is then fed automatically to the second or fine grinding zone, from which it is discharged under its own momentum through a top-mounted discharge chute. The direction of the movement of the material is controlled by fixed 'transition guides' mounted at the end of the material flow channel in each zone. An adjustable grinding zone allows the highest possible output while achieving the finest grind.

A double-ribbon type rotor and close tolerances between the rotor and the body guarantee a very high mixing uniformity. Inspection doors are provided for supervising the activities. The mixer can either be drop bottom type or emptied through manually or pneumatically operated discharge gates located as desired. Capacities range from 250 Kg to 2 Tons per batch, with mixing time of approximately 4 to 6 minutes. The machines are supplied with 5 HP, 10 HP, 20 HP or 30 HP drive motors and gear boxes as required.

The Molasses Mixer is used to mix the required quantity of molasses or other liquid ingredients in premixed batches. Its horizontal design ensures that the mix coming out is of uniform composition and free from lumps or balls. The design allows for the injection of two liquids synchronized with the feeding material. The capacity of the molasses mixer ranges from 5 Tons per hour to 10 Tons per hour.

Pelletizing is a process of compacting finely ground material into a firm mass of the required shape and size by extruding it through a metallic ring die. Finely ground material is fed into the Pellet Mill through a feeder and then pressed into a rotating ring die with the help of two press rolls which are free to rotate on their respective shafts. The resulting pressure compresses the material and extrudes it in cylindrical form through the radial holes in the die.

This is used for breaking the pellets into crumbs required for chicks which are 2-3 weeks old. Pellets are broken into pieces of the required size between the two rolls of the crumbler. The roller gap is adjusted with a hand wheel mechanism. The crumbler is fitted with drive parts which include drive and driven pulley, belt, guard and slide rails for the motor.

The Pellet Cooler is used for cooling hot feed pellets from 80o C to ambient temperature. It consists of an intake box made from Stainless Steel plates with the top cover of bolted construction. On one end there is provision for a mercury switch and on the other end a suitable balancing weight is provided for automatic operation of the discharger. When the column becomes full, the flap gets lifted and the mercury switch operates the auxiliary contact of the starter for the discharger motor and the discharger.

Cooling columns are on either side with central duct for conveying hot air. SS wire mesh separates pellets from air. Set of louvers (flaps) regulate flow of cold air inside the cooler. Pellet discharger has an arrangement for pellet collection and flow adjusting through a mechanism. The discharging mechanism with Spring Steel strips vibrates by means of eccentric drive with pulleys fitted with weights.

It is a composite unit finished with spray galvanised or Stainless Steel slat conveyor of perforated sheets fitted on the chain with a ventilation arrangement and moving over the sprockets with a variable-speed drive. Drying air is percolated through the evenly spread product causing the heat transfer needed for moisture migration. The dryer also includes blower, steam radiator and steam control valves. The exhaust fan is mounted on the drier while the cooling fan is installed at the side. The air from the cooling chamber moves to the pre-heating zone and consequently to the drying zone and finally to the exhaust line. Air circulating fans circulate the hot air through the product on an apron conveyor. Temperature sensors are provided in the heating zone which control the steam inlet to the heating coils. At the bottom two fines-collection conveyors are provided to collect the fines and remove them out of the dryer. A mechanically or hydraulically controlled oscillating spreader is provided at the inlet to uniformly spread the product on the apron conveyor if required.

In order to contain this dust that emanates from the material transfer points while handling grains and powders and keep the working environment clean, all material transfer points are connected with pipes to a central point. This central point is either a cyclone-and-blower combination or a bag filter. The aspiration system generally consists of horizontal or vertical pipelines, bends, Y joints and air valves made from 22 SWG Galvanized Iron sheets to prevent corrosion and make it light in weight.
