What are the methods for heating the pig farm?

You can use the methods of living stove, hot air boiler, radiator, fire wall, electric baking lamp and insulation board to keep warm.

Each pig farm has its own particularity. The capital investment, scale and management mode all affect the selection of heating facilities. Small pig farms or free-range households, due to lack of funds but sufficient manpower, can choose simple and low-cost facilities, such as honeycomb coal stoves, coal stoves, fire walls, fire kang and so on.

Because of the lack of human resources and inconvenient management, large pig farms often choose facilities with high cost but stable effect, such as hot stoves and central heating. In the southern region, because of the short heating time and low requirements for heat, you can choose electric heating facilities or diesel hot blast stoves with easy loading and unloading; Some farmers can also adopt the plastic greenhouse model, which absorbs the heat from the sun to keep their pigs warm.

Extended information:

Stove is a very simple and easy heating method, and many people still choose this method to keep warm. The heating rate of raw furnace heating is very fast, but there are also problems such as relatively small heating area and uneven regional temperature.

In large pig farms and large-scale pig farms, this method is rarely used. There is a risk of carbon dioxide poisoning when a kitchen fire is built in the house, which is one of the reasons why it is rarely used in pig farms. Radiator is a safe and symmetrical heating method, and it is easy to keep the pigsty clean without cinder and dust. However, due to the large investment, the proportion of heating in this way is decreasing.

Hot air boilers are widely used nowadays, and there are more and more new types of hot air boilers. There are different types, such as heating gas before blowing it into pigsty, boiling water before blowing warm air into pigsty with radiator, hot air boiler with electricity, hot air boiler with diesel engine and so on.

Because the hot air boiler blows heat to the pigsty by the centrifugal fan, the temperature of the pigsty is more symmetrical; If the fresh warm air blown in from outside the house is selected, it also has the function of ventilation, which is more beneficial to pigs.

insulation board is a common heating method for newborn piglets and nursing piglets, which has high thermal efficiency and is very beneficial to the survival of piglets; But the difficulty is that the power plug is often bitten off or the line is torn off, which is more serious and leads to the increase of farmers' costs.

Electric baking lamp, which is most used by suckling piglets, uses infrared induction to transfer heat to piglets; The light bulb is also used as the heating mode. Because the general light bulb has different power to choose from, the actual effect will be better than that of infrared induction light bulb for piglets in the second half of feeding.

Firewall is also a very good heating method, but it needs to be planned in advance before pigsty construction because it will occupy the ground area, and it has certain technical content, so it is rarely used by general farmers.
