 STEEL CONSTRUCTION

 STEEL CONSTRUCTION:

Complete structure of the house will be made of steel trusses, steel purlins and steel profiles. Calculation of the steel structure will be based on roof live load of 75kg/m², at maximum wind velocity of 140km/hr.

The main steel structure will be treated with anti corrosion paint, secondary steel profiles and the purlins will be made of sendzimir galvanized steel sheets, and will be fixed to the main frames by bolts.

ROOF CLADDING:

The roof will be covered with “Sandwich Panel” of 40kg/m³ foam density, and shall be of 12cm in thickness.

WALL CLADDING

The walls will have to be made of brick works with openings for the pad cooling and the fans, as your good selves demanded by the end – users.

FLASHINGS:

Special flashing will be used at ridges, eaves, corners, and gables and at all endpoints of aluminum sheets. Flashing will be made of plain aluminum sheet of 1.0mm thickness.

DOORS:

The building will be provided with 2-main doors of 2.10 x 2.00m dimension at front and rear walls and 1 door of 2.00 x 2.00m dimension at partition wall of the Service Room.

The doors will be manufactured from polyurethane insulated aluminum sheet and galvanized steel sheet.

The doors will be air tight and fixed to the mainframe; all the fittings lock handles etc. will be incorporated.

EMERGENCY DOORS:

The building will be supplied with 8 insulated emergency doors of 2.00 x 1.00m dimension for the sidewalls.

PAD COOLING BANKS (20.00 x 2.00M):

Each building will be provided with pad cooling banks will be 22.00m. The main supporting frame will be made of steel tube sections and fixed to the main frame of the building. The pad cooling banks will be cladded with trapezoidal aluminum sheet of 0.70mm thickness. The pad corridor over the pad cooling banks will be provided by the end - users

FAN OPENINGS:

The building will be provided with 11 fan openings. The fan openings will be made of galvanized steel frames to fit the size of the fans.

       EQUIPMENT

    REARING BATTERIES:

Laying Cages will be of  “MBL 637 -MANURE BELT BATTERY FOR LAYERS” Type in (5) rows – (3) tiers with the following specifications:

CAGES:

Cages manufactured partly out of wire and galvanized steel sheets. Battery stands are made of galvanized steel of 1.20 mm thickness. Partitions are made of hollowed galvanized steel sheet of 0.55 mm in thickness. The floor wire is galvanized 150 microns and has a mesh size of 25x38mm.  Easy access via front doors for each cage

FEEDING SYSTEM:

Automatic chain feeding system with separate drive units per tier. Feed trough of 0.65 mm galvanized steel sheets with supports of 2mm thickness. Feed column in front of each start set. Corner wheels with maintenance-free bearings.

DRINKING SYSTEM:

Nipple drinking system for all tiers. 3-Stainless steel nipples over the partition wall of neighboring cages with drip trough.

MANURE REMOVAL:

Easy Manure removal:

Cages are provided with strong endlessly welded polypropylene manure belt under the cages for each tier. Manure drops directly  on this manure belt underneath the cages. A drive unit at the end set and idler roller at the front set carries out automatic manure removal. Manure from each tier is conveyed onto the manure cross belt at the end of the battery. Manure belt scrapers at the end set clean the polypropylene belt on each tier.  The manure cross belt conveys the manure onto the manure elevating belt situated out of the house.

FEED SILO:

One out door feed silo capacity 10 tons for each house. The silo is equipped with pneumatic filling with auger, over flow pipe, protected ladder. The silo supplies the feed direct to an external feed hopper that is situated inside the control room, used for manual feeding, and then to the feed hoppers in front of the battery lines through flex-way auger system. The silo is equipped with two glass windows.

DRINKING WATER:

Two internal water tanks each 500 liters capacity, made of glass fibre reinforced polyester. The water tanks are equipped with supply and drain off valve and with pump to supply medicated water to distributing tank at the each tier of batteries.

LIGHTING SYSTEM:

Lighting system is designed to provide a light intensity of 6W per square meter and arranged in 6-longitudinal lines over walkways. Lamps of 60W pin type bulbs hanged 2m over finished floor of house. The lighting system is controlled by a dimmer. For the service room 2-florescent lamps will be provided. A lighting unit of 100W will be supplied for front and rear gable wall.

ALARM SYSTEM:          

Each house will be provided with an alarm system for detection of:

• Over temperature

• Under temperature

• Electricity and main power failure

• Heater failure

Alarm system operates by visual and acoustics signals.

VENTILATION AND COOLING SYSTEM:

Exhaust ventilation system will be applied. The fans will be placed at end of the sidewalls and rear gable wall while the pad cooling system will be located at the opposite ends of the sidewalls.

• A ventilation rate of 14m³/h per bird will be provided, based on 7m³/kg of live weight of layer.

• Average live weight of each layer: 2kg.

• Total ventilation capacity: 352’800m³ per house.

• 48’’ fans of 32’400m³/h capacity at 5mm W.C. will be used.

• The number of the fans per house: 11

Cooling pads will be located on the sidewalls in cooling corridors. Aluminum wall of the corridor will protect the pad from direct wind and dust. For each house 84m² pad area is planned.

The height of the pad is 2.00m and thickness is 10cm. Pad cooling system will be complete with water supply system, distribution pad, return gutter, water tank and pump.

Efficiency of pad cooling system

Starting condition:

50^oC, 25% relative humidity

Wet bulb temperature 23^oC

Air entry temperature: 27^oC

Average House Temperature: 29^oC

The durability and the functioning of the pad cooling system can be negatively influenced by following conditions.

• The use of chemically polluted water

• The use of dirty water

• Quality of the water.

AUTOMATIC CONTROLLING OF VENTILATION, COOLING AND HEATING SYSTEM:

Ventilation, cooling and heating systems will be controlled by an electronic thermostat.

CENTRAL ELECTRIC CONTROL PANEL:

A central switch panel will be located in service room and contain all necessary electrical equipment such as the main circuit breakers, contactors, terminals, control-switches and motor protection switches.

System is complete with all wiring system from central electric control panels to all motors inside the poultry area. Cables will be NYM type and 600-1000V insulation grades.
