Core tips
The cold weather in winter, raising chickens to chicken coops to heat up the use of large amounts of coal, so that the growing cost of farming, breeding profits decreased significantly. In order to save coal, reduce feeding costs, and increase the profitability of chickens, if energy-saving measures such as the installation of thermostats, air ducts, heaters, pendants, and insulation sheds are used, both the insulation effect of the chicken house can be improved. It can maintain the fresh air in the house and reduce the occurrence of diseases, so as to reduce the cost of raising chickens and increase the income of breeding.
Install thermostat
Use the thermostat to control the temperature and ventilation of the house to achieve minimum ventilation management. The minimum ventilation rate for broilers on the net is 0.0017 cubic meters per minute. This can not only meet the chicken's normal growth and development needs, but also save coal. It also reduces the cold wind on the chicken body. Stress.
Install air duct
An air duct with a diameter of 16-18 cm and a length of 3.5-4 meters is installed every 4m on the two sides of the chicken house wall and installed along the ceiling. Lightweight materials such as plastic, polyvinyl chloride (PVC) and fiberglass are used. Can help to control the minimum ventilation, while avoiding cold wind directly to the chicken body, reducing the chicken's stress response. This will not only maintain the indoor temperature, but also ensure the quality of air and reduce the occurrence of respiratory diseases. If you take this measure and close the air intake, you can save energy and improve the feeding efficiency.
Heating stove heater
Among all the heating methods, the heat efficiency of the warm air heater is the highest, and the temperature rise is fast, which can satisfy the need of the chicken house temperature to the maximum extent, and it is beneficial to save the cost. Because the temperature difference between exhaust gas and supplemental fresh air in the winter house can reach 30°C-45°C, there is also a difference in humidity between the exhaust gas and fresh air, and waste heat (including sensible heat and a small amount of latent heat) has a certain utilization value. Therefore, in order to solve the contradiction between ventilation and ventilation, it is possible to use the waste heat heater in the exhaust gas to reduce the energy waste and improve the breeding efficiency.
Promotion of flues
If furnace heating is used, the circulation length of the chimney should be extended as much as possible so that the heat generated by coal combustion can be distributed in the chicken house as much as possible to reduce the waste of heat energy. The smoke outlet should not touch the heat, and the length of the chimney is generally. About 20 meters.
Build insulation shed
At present, some farmers use the method of constructing plastic film insulation sheds on the front and rear sides of the chicken house to use solar energy. This not only absorbs the heat of the sun, but also reduces the heat loss of the chicken house, and it can save about one-third of energy. Avoid cold wind directly into the coops causing cold stress, this new measure has been recognized by the majority of farmers.
Other good measures
1. Blocking windows If conditions permit, you can use plastic steel, aluminum alloy doors and windows, glass with double thick specifications, although the cost is high, but eliminating the cumbersome year after year plugging. Poor conditions can be achieved by using polystyrene board, cotton curtains, and multi-layer plastics to seal the windows, and then use wood or cardboard to reinforce and nail the inner thermal insulation material to avoid cold wind directly entering the shed. The insulation effect.
2. Interior ceilings For ceiling heights or poor roof insulation, ceilings (plastic or polystyrene panels) can be suspended in the house or a layer of insulating cotton felt or straw (straw, wheat straw) can be placed on the roof. Etc.) to improve the insulation effect and reduce heat loss.
3. Increase the thickness of wall Some chicken farms have thin walls. In order to reduce the loss of heat and maintain the indoor temperature, a layer of polystyrene board can be used inside or outside the wall. The thickness of the board can be based on the thickness of the wall. Flexible control, if done well, this measure can save a quarter of energy.
4. Set up the ground or underground flue If the chicken house is provided with underground or above-ground flue for heating, a certain amount of fuel should be added, and at the same time, attention should be paid to preventing flue gas leakage. The above-ground flue gas is hotter than the bottom flue, and the utilization rate is high. The underground flue gas duct saves space compared to the above-ground flue gas duct.
5. Use hot air bags or chickens in water-heating houses to produce chickens outside the house. Heat the house through hot air or heating pipes, and pay attention to ventilation and fire prevention. The crater should be located outside the house, but the coal stove can also be placed in the house. However, a certain number of vents should be kept in the house.
