Many would not refuse the additional source of Finance during economic crisis. One effective method is breeding birds. For incubation and short term detention of juveniles do not need much space and feed compared to cattle breeding.
Enough to buy an incubator or make it yourself.
An integral part of the incubator is the thermostat, which control temperature and humidity inside the structure, which is necessary as the natural conditions for the development of the embryo. Also required periodically to ventilate the incubator to control the frequency of perevorachivaet eggs.
The main parts of a controller:
- thermometer for data transfer to a control unit integrated in the main;
- the main control unit. The main voltage for the heating element. The head unit is the setting important parameters;
- heating device − a Converter of electric energy and heating the air (heating elements, incandescent lamps, which differ in the precise heating and durability).
Before the advent of the thermostat business owners trying to pick up lamp with optimal power, use the air gap for heat control. The failure temperature becomes the cause of late hatching Chicks, their weaknesses and disabilities. Currently, this problem is easily solved with the purchase of the thermostat in the shop of electrical appliances.
The most common thermostats for incubators with their hands − based on a thermostat and electrical. The latter requires high skill and considerable knowledge. In the collection of the incubator from scratch recommended universal controllers XM18, allowing you to connect all the electrics in one block.
To create the necessary conditions will need a thermometer bulb, a thermally insulated container for eggs, the time to shut off the heat source and temperature control. First you need to choose the right design, heat-trapping, like the refrigerator. This volume can accommodate up to one hundred eggs.
To make the thermostatneeded a Zener diode or similar part is responsible for a constant voltage. In addition, you need the following items: transistors, thyristors, diodes, a variable resistor, the thermal relay.
Light elements should be located on the perimeter for better heating. Inside the device you need to place a fan or build a hood. If the indicators do not correspond to normal, otherwise you need to convert interior space: reinstall the lamp, close the hood, attach the fan inside.
Incubator with thermostatic control shall be fitted with a turning mechanism. Hourly side heating of the eggs will change for the uniform development of the embryos of Chicks. If you carry out it manually, the desired effect is not achieved. It is desirable to provide the possibility of removing large and small eggs, providing changes in market demand.
You can’t place the incubator in direct sunlight: in this case the readings will be erroneous.
First day of heating need to carefully control the temperature regime. The slightest overheating detrimental effect on the chick embryo, resulting in all further work of the incubator will be in vain.
Additional conditions are: the temperature of the air in the room (at least 25 degrees) and a constant flow of fresh air.
The types of thermostats
Electronic thermostat for incubator have high sensitivity. They are part of an electronic circuit and a temperature sensor. Data to control the circuit receives from the temperature sensing element is a thermistor. At the core of the management process − change in current or resistance.
Mechanical thermostat is used to control Autonomous technical installations. It is not suitable for working with electricity. Heat is gas convector, stove − possible fields for their application. The work is based on the linear dimensions of the thermoelement. Its disadvantages are: low resolution, only the temperature regime, the complexity of fine tuning, the need for a separate thermometer.
Electromechanical thermostat for incubator works on the basis of changes in properties of materials, opening the contacts mechanically. The role of the temperature sensing element can perform two metals with different expansion coefficient.
Digital thermostat for incubator is characterized by the accuracy of measuring the temperature of 0.1 degrees Celsius (mercury and alcohol have significantly inflated the figures). Thermostats for incubator PID different from the previous gradual switching. Thus there is not separation of the contacts, and a gradual decline in the current strength. The temperature is stable without the on-off switch.
Thermostats for incubator with temperature sensor the most accurate, therefore used for many types of eggs, susceptible to the slightest fluctuations of temperature. Weight of the device affects the response speed of the regulator.
The operation of the thermostat
The performance of the controller has the following pattern:
- A heating element located inside the incubator, gives off heat to the air. Use the system discharge for the purpose of uniform heating of the air.
- When reaching the limit temperature, the heater circuit is opened and the supply of heat is terminated.
- If the temperature becomes insufficient, the circuit connects again.
It is worth noting the efficiency of infrared heaters incubators: the heat is distributed directly on the objects of heat without the aid of air. But in this case, it will have to control the temperature of the eggs, that is more difficult.
The incubator can be purchased with any necessary options, selecting from a range of universal or narrowly specialized devices, domestic or foreign production.
Important parameters of the incubator
When choosing the incubator have a value parameters:
- compliance to incubate eggs of any type;
- the uniformity of heating of the interior air space;
- the natural conditions for aging Chicks;
- automatic adaptation of the coup eggs;
- egg capacity;
- the presence of the viewing window;
- the prevention of loss of oxygen;
- the ability to work from battery.
- moisture control;
- the error in the temperature measurement;
- independence from room temperature;
- the presence of built-in memory;
In the catalog of known manufacturers are presented popular modern thermostats for incubator: the mother hen, the Hen-Bi, Cinderella, Lagurus, the Perfect hen.
When selecting a thermostat for incubator should take into account the possibilities of homemade design. Small enough device controller of temperature and humidity, and the greater number of expensive options, the regulator will remain unclaimed.
Incubation − a profitable and exciting experience, combined with technical refinements, it becomes popular for many years.
