How to correctly use mist cooling measures in pig farms?
So much detail on the mist cooling? How to correctly use mist cooling measures in pig farms?
The heat is a severe test for pig producers. When the temperature of the pig house reaches more than 30 ° C, pigs are prone to heat stroke, especially large pigs and pregnant sows. Therefore, doing a good job of heat prevention and cooling is very important for maintaining a balanced litter and improving efficiency, and it is one of the main jobs of pig farms in summer.
There are many ways to prevent summer heat cooling, and there are many equipment. Today, i will share with you the correct application of mist cooling in pig farms. The biggest advantage of the cooling method is that it is easy to install in the existing livestock house, the cooling speed is fast, and the temperature in the house can be reduced by 5 to 8 ° C in 5 to 10 minutes, and the mist device can also be used as disinfection.
mist cooling, the use of pressurized water, through the mister nozzle, the formation of small droplets, floating in the air in the greenhouse, with the air heat and humidity exchange, to achieve the effect of evaporation and cooling.
However, the mist will hit the wetland surface, cause water on the ground, and make the pig in a high humidity environment for a long time, which causes harm to the environmental health of the pig house, so pay special attention to the use of the mist device when cooling, mainly in the selection of the mister nozzle, the height of the mister nozzle installation and the mist time.
First, the choice of mister nozzle, the key is the mister nozzle to atomize well. The performance of the mister nozzle directly affects the quality of mist, and the quality of mist directly affects the cooling effect. A good performance mister nozzle, not only can provide good mist effect, but also should consume less energy. Such as fine mist, even the humidity of the fermentation bed is not harmful, because the water generally rarely falls into the bedding, but is atomized in the air, and absorbs the heat in the air and evaporates, and will not fall on the bed.
The second is the height of the mister nozzle installation, the droplets run in the pig house, due to the initial speed of the droplets and the role of gravity, the droplets will move downward. If a large number of small droplets are inhaled by pigs, it is easy to lead to respiratory diseases, from this point of view, the space for the droplets to run in the pig house has certain limitations, that is, the droplets should completely evaporate above the back height of the pig, that is, the height above the pig stall. The specific height is determined by the selected mister nozzle pressure and the mister nozzle device Angle.
The third is the time of misting, taking the intermittent operation of the working mode, mist cooling, as the temperature drops, the moisture content of the air increases. After a certain time (about 1-2 minutes according to the test), the moisture and heat balance is reached, and the water vapor content of the air in the house is close to saturation. Therefore, the mister nozzle must periodically work intermittently, depending on the temperature, humidity, ventilation and other conditions.
