Research and Application of Raising Pigs in Air Building Mode
Expert Advisor——Wang Zhenhong
Wang Zhenhong——Dean of CIMC IoT Intelligent Breeding Planning and Design Institute. The major is animal husbandry and veterinary medicine, specializing in large-scale pig farms, chicken farms, cattle farms, sheep farms, rabbit farms, pigeon farms, quail farms and other large-scale farm planning and design and breeding equipment research and development design, production, installation and operation and maintenance It has been twenty-five years. He has provided design and EPC general construction services for Liuhe Group, Zhengbang Group, New Ng Fung Group, Twins Group, No. 1 Food Group, Jiangfeng Group, Hongmen Group, Yangxiang Group, Young Eagle Group, and Wens Group. At present, there are more than 200 large-scale farms designed and put into production at home and abroad. The professional and practical patented technology has been recognized and praised by many customers. And published more than 20 professional technical papers, related technologies have also been practiced and promoted a lot!
The pioneer of Qilou mode breeding, the invention patent has been effectively promoted and applied in the pig industry, and the professional technology has been recognized by the breeding enterprises!

Current status of pig farm design and layout
Affected By Wind Direction
Difficult to distinguish between clean and polluted areas, the polluted air from the polluted area is blown to the clean area and sucked into the pig house through the strong wind direction, forming a vicious circle; the whole site is smoky and the air quality is not ideal, which directly affects the pigs Respiratory diseases, causing cross infection!
Influenced By Land Resources
Now, it is very difficult for breeding enterprises to vigorously develop and find a piece of land suitable for raising pigs! In order to develop, some enterprises have set up a professional land selection research team to select land suitable for raising pigs! Some enterprises simply expand the scale (extend the roof and rebuild the ground between the two buildings) in the original pig farm (10-15 meters between the buildings).
Affected by environmental pressure
A. Breeding waste and gas --- the pressure given by the environmental protection department
B. The wind direction of the exhaust gas is affected by the pressure of the common people---complaints and interference with production
Biosafety, environmental protection pressure, high-efficiency and low-cost pig raising have always been topics that the pig raising industry cannot avoid.
Since 2014, the scope of the delineation of the no-raising areas in the country has continued to expand. The requirements for the construction of livestock and poultry farms within the areas of no-raising areas, restricted areas, and suitable areas have become clearer and clearer. Governments at all levels have increasingly stringently supervised pig farms.
The outbreak of African swine fever in 2018 brought catastrophic losses to China's pig industry, and also made the entire pig industry realize the importance of biosecurity for the survival of a large pig farm. In the overall site selection and planning and design of pig farms, the design and establishment of biological safety are also considered in the most important position!
The air building mode blocks the link of "infection source-transmission route-susceptible animals" of animal diseases through construction projects, and blocks pathogens from entering the pig farm from the source. The air building mode pig house degasses according to air flow and chimney effect The principle continues this design, and innovates and optimizes on this basis.
In 2019, the Qilou model pig farm combined the essence of domestic and foreign advanced technologies to design and solve the industrial pain points in the production of pig raising in buildings, and formed a unique invention patent (ZL201910112131.1)
Air building model design ideas
Design principle of air building mode
Air tower pattern design style
Air building mode supporting system
Design principle of gas building mode (chimney effect)
Taking advantage of the higher air temperature and pressure on the ground and the lower air temperature and pressure at high altitudes, the difference in temperature and pressure causes air to flow from places with higher pressure (ground) to lower pressure (high altitude), and humans build chimneys to discharge smoke and dust. The same principle applies to high altitudes.

Advantages of air building mode farming
Pig farm traditional design layout
Air tower mode layout
1. Improve land utilization rate and reduce land lease cost
Reduce the crossover of dirty and odorous gases in the farm area, and reduce the chance of respiratory diseases in pigs.
Taking advantage of the higher air temperature and pressure on the ground and the lower air temperature and pressure at high altitudes, the difference in temperature and pressure causes air to flow from places with higher pressure (ground) to lower pressure (high altitude), and humans build chimneys to discharge smoke and dust. The same principle applies to high altitudes.
It can improve the air quality of the field and reduce the cost of the entire field of medication.
Conducive to centralized deodorization of pollutants and reduce complaints from surrounding residents.
It can effectively use the waste heat of exhaust gas and reduce the input cost of heat preservation.
Natural ventilation can be carried out to reduce the operating cost of pig raising.
Centralize IoT management to reduce pig raising operating costs.
Since 2017, the Qilou model of pig raising has been promoted nationwide
