1. The vertical fan
The purpose of the fan installed in the poultry house is to exhaust waste gas and draw in the fresh air in it. On one hand it can get enough oxygen and exhaustcarbon dioxide; on the other hand it can exhaust the hot air and draw in the cold air from outdoor, and having a cooling effect.
In addition, fans can also be used in conjunction with the cooling pad (as shown in Figure 1), which play cooling effect better in the hot summer. Thus the fan is very important in the whole feeding process.
We circulate maximum air flow capacity according to renew all the air in the poultry house in one minute. The amount of fans is the value that the maximum air flow capacity divides the air flow capacity of one fan. The vertical fan generally installed in one end of poultry house (as shown in Figure 1). Figure 2 shows the ordinary fan, according to user requirements one can also choose fans with cage and wind-cone.
2. The horizontal fan
The horizontal fanis generally used for the winter or brood, the vertical fans can instead of it. The horizontal fan can be configured according to user’s requirement, and installed equably on one side wall in the poultry house (as shown in Figure 1).
3. Fan Light shield
The purpose of light shield is to control the light, namely protecting the poultry house from shining. Light shield generally installs on the fan mouth within the poultry house, which is generally needed to install in close type breeder house (as shown in Figure 3).
4. Ventilation window
Ventilation window (as shown in Figure 4) isgenerally evenly installed on both side walls of the poultry house, as shown in Figure 1. To prevent birds and rodents and other small animals entering the poultry house from the ventilation window, the bird netting needs to be installed on the ventilation window (usually installed outside of the ventilation window).
Ventilation window light shield is generally installed outside of the poultry house, and prevent light from shining the poultry house when the ventilation window is opened.
5. Cooling pad
Obtained the number of fan needed in poultry house by calculating, then you can calculate the area required for the cooling pad. Cooling pad is generally installed on the opposite end or the both side walls of the opposite end (the opposite end to the vertical fan), as shown in Figure 1.
5.1 Cooling pad work principle
When the dry air outside the poultry house blows the cooling pad, the water film in cooling pad absorbs heat of the air then evaporates into the water vapor, making the air into the poultry house cool and moist and playing a significant cooling effect, as shown in Figure 5.
5.2 The framework of the cooling pad
There are three cooling pad framework:
Ø the use of hot galvanized steel sheet, simple structure, high strength, low cost;
Ø the use of PVC section (plastic), light weight, lower cost, poor intensity;
Ø the use of aluminum, beautiful appearance, corrosion resistance, good strength (recommended).
5.3 Cloth for cooling pad
Cloth for cooling pad is put on the mouth or outside of the cooling pad (as shown in Figure 6). When not using cooling pad, the mouth of cooling pad can be blocked to prevent air entering the poultry house; when using cooling pad, just open the cloth. Cloth for cooling pad can be controlled automatically or manually.
5.4 Water for cooling pad
According to the principle of cooling pad, it is effective with the enough cold circulating water available when cooling pad works. Water capacity for cooling pad requires 60kg/min per square meter, water tank or pool’s volume is 1 / 6 that of cooling pad body.
6. Heating system
6.1 The purpose of heating
In order to maintain the temperature inside the poultry house, when at a lower ambient temperature (e.g. winter) or brooding time, workers must raise the temperature to make environment comfortable for the growth. We usually use heating way to raise the temperature. There are some heating methods currently: coal-fired, oil, fuel gas and electricity heating.
Stove: coal stove, oil stove and fuel gas stove.
Coal-fired stove’s fuel is coal that is generally installed in the duty room at one end of the poultry house (as shown in Figure 7). The hot air is blow into the poultry house with an air supply pipe (as shown in Figure 8). Advantages: lower operating costs. Disadvantages: There is some air pollution.
Oil stove’s fuel is kerosene or diesel fuel. There are two installation methods: one is installed in the duty room at one end of the poultry house the same to coal-fired blowing the hot air into the poultry house with an air supply pipe. The other is hanging in the poultry house directly, as shown in Figure 9, the exhaust gas discharged from the poultry house through the special chimney.
Fuel gas stove’s fuel is liquefied petroleum gas; generally require suspension in the poultry house, as shown in Figure 10.
7. Insulation umbrella
Insulation umbrella be divided into electrical insulation umbrella and gas insulation umbrella. Electrical insulation umbrella’s power is 1.2kw / one, each insulation umbrella can brood 500 chickens, and it should separate chicks with fence. Liquefied gas insulation umbrella is the same to electrical insulation umbrella. It can brood 500 chickens and should separate chicks with fence.
8. Lighting system
Lighting system is designed to control the light intensity and illumination time in poultry house, in order to obtain the required illumination. The purpose of illumination is to provide adequate brightness to ensure the chicken feeding and watering normally. Light must be uniform. Different varieties of chickens and feeding at different stages, the need of light intensity is also different.
To save energy, most broiler houses use energy-saving lamps to light. Energy-saving lamp has the advantage of saving energy, less heat. In order to reduce the stress caused by light in breeder house, it can use slowly light and dim to control the lighting. It can only use the incandescent lamps when using the way of slowly light and dim, for energy saving lamps cannot achieve that effect.
Light modules: You can open or close the light with the setting time in the light module, slowly light and dim when switch ing, which can be achieved automated or manually (coordinating with the poultry house climate controller), as shown in Figure 13.
9. Silo
Silo is made from the high quality material of hot galvanized steel, it generally transport with spare parts and assemble on-site. Silo consists of tower, support, ladder, bottom, lid and other components, as shown in Figure 14.
10. Spray disinfectant system configuration
Spray system consists of nozzle, pipe, high pressure water pump and other components. Nozzle is copper nozzle. There are PE pipes and stainless steel pipes.
11. Electric winch
Electric winch installed above the waterline or feed line, usually one for each line and two for hen ring feeding line. When you press the switch with toward up or toward down, the entire line move up or down simultaneously, as shown in Figure 15.
12. Power failure alarm
The power failure alarm system is installed in each house. It Includes: power failure alarm, sound and light alarm, communications cable (from the strong electric control cabinet to the power failure alarm), if you concentrate to alarm, you need to install a communication cable from each house to office of the factory. Power failure alarm’s main function is to test the power of access equipment, as it can monitor power-off phase, partial phase and lack phase and achieve sound and light alarm.
13. Electrical shock anti-roost assembly
Electrical shock anti-roost assembly mainly produces high voltage, safe current to prevent poultry standing on the feed line or water line. Electrical shock anti-roost assembly’s one pole connects to steel tube of the feeding tube or waterline and the other pole connects to the anti-roost wire rope.
14. Fan control cabinet configuration
Fan control cabinet size depends on the number of fans. Each fan can be manually controlled, but also can be automatic control (to be associated with the climate controller). There are two kinds of fan control cabinet: one is like that control and operation are all in one, usually be installed in the control room and has more fan power cables; the other is separate the control from operation, control part installed near the vertical fan, operating part installed in the control room. The two control cabinet can be connected just with a signal cable, if an integrated control cabinet is needed, operating part can be integrated with integrated cabinet together, which can save a lot of fan power cables.
15. Integrated control cabinet configuration
Integrated control cabinet is to control all other electrical equipment in addition to the feed line and fan in the poultry house, including: cooling pad pump, stove, electric winch, lighting, conservancy machine, ventilation windows-drive mechanism. All controls can be manually or automatically (to be associated with the climate controller). One of them is electric winch which can turn forward and reverse.
16. Cable and trunking configuration
For security, all cable must be added jackets or placed in the wire groove to prevent rats and other small animals snapping cable to cause equipment failure or casualties.
Wiring requirements:
Ø Every house should have ground wire, ground wire requires should be in line with national standards.
Ø Outdoor power cord and power lines (from the transformer of field to the power line of poultry house, etc.) should use cable or sheath wire, wire is strictly prohibited bare.
Ø Wiring alignment to avoid heat, water, and direct splar radiation.
Ø Wiring alignment should be beautiful, with good logo.
Ø Strong and weak electronic are best to go separately and isolatedly, preventing mutual interference.
Ø Cable includes power cable and test cable.
Power cable is from the control cabinet to the drive motor, generally is 4-core cable, including: feeding motor, the fan (vertical and horizontal fan), heater (stove), cooling pad pumps, cooling pad cord drive motor, ventilation windows driving motor, electric winch, etc.
Detection cable is generally two-core cable, including: detect switch from the control cabinet to the detection material plate, protection switch of motor box when full of material, hopper switch for lack of material and temperature and humidity probe lines, etc.
