How to choose equipment for pig farms?
1. Heating equipment
Heating is divided into two types: central heating and local heating: central heating uses a central heating device to generate heat medium, and then pipes the heat medium to the radiator in the pig house. Local heating includes hot water heating floor, electric heating plate, infrared lamp, etc. Ventilation equipment The ventilators suitable for pig farms are mostly large-diameter, low-speed, low-power ventilators. This fan has large ventilation, low noise, low power consumption and durability. Ventilation should pay attention to the following issues:
(1) Avoid short-circuiting the ventilation of the fan. The fan must not be installed on the wall. The door is below to make the air flow short-circuit;
(2) If a single-sided exhaust is used, the exhaust outlets of the adjacent pig houses on both sides should be set on the opposite side to prevent the exhausted air from being inhaled by another pig house immediately;
(3) Try to make the air flow through most of the space in the pig house, especially on the manure ditch, and don't create dead corners to achieve the purpose of ventilation.
2. Cooling equipment
Although ventilation is an effective cooling method, it can only reduce the room temperature to close to the ambient temperature outside the room. Nowadays, the commonly used cooling systems in pig farms include wet curtain-fan cooling system, spray cooling system, spray cooling system and drip cooling system. Because the latter three cooling systems have high humidity, they are not suitable for farrowing houses and breeding houses. The wet curtain-fan cooling system is currently the most mature evaporative cooling system. Its evaporative cooling efficiency can reach 75%-90%, and it has gradually been widely used all over the world.
3. Disinfection equipment
Commonly used on-site cleaning and disinfection equipment for pig farms include high-pressure cleaners, flame disinfection and knapsack sprayers. According to reports, the best effect can be achieved when the flame sterilizer is used in conjunction with drug disinfection. After the drug is used for disinfection, the flame sterilizer is used for disinfection. The sterilization can reach more than 95%.
4. Cleaning equipment
Modern pig farms generally have feces leaking floors on the feces and urine ditch. After pigs defecate and urinate on the feces leaking floor, the urine flows into the ditch through the gaps, and the feces fall on the feces leaking floor and fall into it automatically after being stepped on. In the lower manure ditch, so as to avoid contact between pigs and manure, it is helpful to prevent and reduce the occurrence of diseases.
According to its laying range in the pig pen, the slatted floor can be divided into two forms: full leakage and partial leakage. The farrowing pen and nursery pen raised on the high bed should adopt the full leakage floor and raise on the ground. The pigpen generally adopts partial leakage floor (1/3-1/2 leakage floor). The draining pond area for pigs is a leakage floor, while the feeding and resting area is a solid ground. The key technical parameter of the leakage floor is the width of the leakage. Fecal leakage floors come in various shapes, generally made of blocks, strips or nets. The materials used are cement, metal, plastic, etc.
