Incubator structural performance and selection use
The creation of suitable factors for the embryonic development of poultry eggs, the acquisition of a large number of good quality chicks and the selection of excellent incubator equipment are of great importance. Here we will introduce the main points of choosing an incubator. Structure and performance of the comprehensive incubation equipment status, the domestic and foreign production of incubator structure is basically the same, the box is generally used color steel or glass steel plate for the inside and outside the board, the middle insulation with a foam sandwich, and then use a special combination of aluminum connections, box Inside the body, a large-diameter mixed-flow fan is used to stir the temperature and humidity in the incubator device. After the egg racks are all welded and fixed with angle iron, the turbine worm-type reducer is used to drive the transmission. The egg-turning operation is slow and smooth without shaking. The special egg trays for different eggs are placed one after the other into the egg racks. According to the technical parameters set by the operators, the incubator equipment is equipped with automatic constant temperature, automatic humidity control, automatic egg turnover and reasonable ventilation. The full automatic function of ventilation ensures the hatching rate of fertilized eggs. At this stage, when the number of excellent incubator equipment is fuzzy, the main features of the equipment are: temperature, humidity and damper control, which reduces the fluctuation of the temperature field, reasonable negative pressure air intake, and positive pressure exhaust methods. The tuyere forms a negative pressure, inhales the fresh air, stirs it into the hatching egg area evenly after heating, and finally exits through the air outlet. When the ambient temperature of the hatchery is high, the cooling system will automatically open, and the air-cooling will be implemented. The air door will automatically open to the maximum and accelerate the exchange of air. The new heating control method can automatically adjust the heating power according to the ambient temperature, the heat dissipation of the machine and the embryonic development cycle, which is both energy-saving and precise in temperature control. There are two sets of temperature control systems. When the first system is in operation, the second system monitors the first system. In the event of an over-temperature phenomenon, the second system automatically cuts off the heating signal and emits an audible and visual alarm to improve the equipment. reliability. The second set of temperature control system can independently control the heating work. The system also has a special heating compensation function to ensure maximum temperature stability. Heating, humidifying, cooling, turning eggs, dampers and fans all have indicator lights to indicate the working status; high and low temperature, high and low humidity, damper failure, turning eggs, fan belt stop, power failure, phase loss, and current overload Can be different voice alarm; panel design is simple, easy operation and use. How to choose farms and breeding professionals in the purchase of incubators, should consider the following aspects: 1. The level of hatching is the most important indicator to measure the quality of equipment, but also many hatcheries spare no expense to replace the advanced incubator equipment . The temperature field inside the machine should be uniform, there is no temperature dead angle, otherwise it will reduce the hatching rate; the accuracy of temperature control, Han Xian intelligence is better than fuzzy computers, blur computer is better than integrated circuits. 2. Machine use costs, such as electricity and maintenance costs. 3. The circuit design should be reasonable, and there should be perfect aging detection equipment; in addition, the whole machine should be tested for aging for a period of time before it can be used after it is tested. 4. Good after-sale service. One is the speed of service; the second is the long-term service. As far as possible, large-scale manufacturers with good development momentum and long-term services should be selected. 5. Long service life. The service life mainly depends on the material of the material, the thickness of the material used, and the quality of the electrical components. In addition, the product category is also a particular area of ​​attention when choosing a hatchery. Precautions for use 1. Before use, perform a complete system check on the entire machine, such as whether there are debris in the machine, whether the moving parts are flexible, whether the insurance is intact, whether the external wiring is correct, and whether the power supply voltage used is qualified, if the voltage is not Stable, the best regulator. 2. Before the machine is officially hatched, it should be placed in a suitable location. It requires good ventilation and the machine is stable. It should be placed on a thick layer of brick or concrete. 3. Turn on the total line switch (regulator) before turning on the power, and then turn on the power switch. The electronic control light is on. The fan switch is turned on, the large fan is turned, the heating indicator light is on, and the heating tube works. Finally open the egg switch again. The alarm button can check if the alarm line is good. The lighting switch can be turned on or off as needed. 4. After power on, you should observe whether the fan rotation is normal, whether the turn-turning mechanism is working properly, whether the flipping angle is appropriate, and whether the control condition is good. After two days of startup, it is determined that the machine is working normally, and then eggs are laid for incubation. 5. When feeding eggs, switch the egg switch must be closed. Shake the egg rack with a rocker, and then put and take the eggs. Then, turn on the switch, turn the egg turning mechanism to set the angle, and return to working condition. Be sure to shake the handle in the direction of the arrow when turning the egg. 6. Check the tightness of the belt frequently. If it is too loose, the air volume is small, the ventilation is bad, and the temperature difference inside the machine is large. If the tightening is too tight, the belt and motor life will be affected. 7. When the production is not busy every year, the whole machine must be cleaned, and the bearings are filled with butter for maintenance.
