Among the many factory-made incubators, the Nesushka device is in good demand. A manufacturer from Novosibirsk produces models Bi 1 and Bi 2. They are almost identical in design. In general terms, the device consists of a box, inside of which there is an egg grill and a heating element. The temperature is maintained automatically, which includes a control device. Applicable thermostat for incubator There are two types: digital and analog. We will now talk about the differences between automation and the devices themselves.
General characteristics of laying hens
Let's start our review of incubators Bi 1 and Bi 2 with the body. It is made of foam plastic. Due to this, the manufacturer reduced the cost of the product. Incubators with similar characteristics, with a plastic or plywood body, are more expensive. Plus the weight of the device itself has decreased.
This is where all the advantages end. The hatching egg gives off a lot of unpleasant odors. It may be contaminated or simply rotten. All these secretions are absorbed by the foam. After each incubation, the body will have to be thoroughly treated with a disinfectant. In addition, polystyrene foam is fragile. He is afraid of the slightest mechanical impact, as well as cleaning with abrasive substances.
The bottom of incubators Bi 1 and Bi 2 is made with recesses for water. The manufacturer refused to use remote baths, as they take up free space. Water in the incubator is needed to maintain the required microclimate.
The heart of the device is automation. You can monitor the degrees inside the incubator using the built-in thermometer. But to regulate the temperature, you need a thermostat. On models Bi 1 and Bi 2, two types of devices are used:
- In an analog thermostat, temperature changes are performed mechanically. That is, they turned the handle to the right - they added degrees, turned it to the left - they reduced the heating. Typically, an analog thermostat has a reading accuracy of 0.2OWITH.
- A digital thermostat is more accurate and convenient, where all data is displayed on an electronic display. Improved models are equipped with an additional humidity sensor. Such thermostats display data on the temperature and humidity level inside the incubator on the display. On a digital device, all parameters are set by buttons and stored in memory. As for the temperature error indicator, for an electronic thermostat it is 0.1OWITH.
Any Laying Hen Bi 1 or Bi 2 is equipped with a small window on the top cover. Through it you can monitor the condition of the eggs and the appearance of the chicks. In the event of a power outage, the incubator can operate on battery power for up to twenty hours. The battery is not included. If necessary, the poultry farmer buys it separately.
Model Bi 1
Laying hen Bi-1 is sold in two versions:
- Model Bi-1-36 is designed for laying 36 eggs. Conventional incandescent lamps are used as a heater.
- Model BI-1-63 is designed for simultaneous incubation of 63 eggs. Here heating is already carried out by special heaters.
That is, the difference between the models lies only in the capacity of the eggs and the type of heating elements. Both models can have automatic egg turning. There is a complete set of Layers Bi-1 with a digital thermostat with a psychrometer function. It allows you to receive information on the display about the level of humidity and temperature inside the incubator.
Model Bi-2
The Bi-2 incubator is designed for a large egg capacity. This is the main difference between the model and Laying Bi-1. As in the case of the considered device, Bi-2 is also available in two modifications:
- Model BI-2-77 is designed for incubating 77 eggs. Among this modification, this device is considered one of the best. The incubator is equipped with a powerful and high-quality thermostat, which allows you to accurately maintain the set temperature in all parts of the free space around the eggs. The maximum error can be as low as 0.1OC. During operation, BI-2-77 consumes a maximum of 40 W.
- Model BI-2A is designed for laying 104 eggs. The incubator is equipped with a digital thermostat with a psychrometer function, but can also be produced without a humidity sensor. The incubator comes with a set of egg racks with different cell sizes. The power of BI-2A is a maximum of 60 W.
Among this modification, the BI-2A model is considered successful in combining low cost with a digital thermostat.
The video shows how to assemble the incubator:
Any Laying Hen model comes with instructions from the manufacturer.It indicates how to prepare the device for operation, and also provides a table of temperatures for different types of eggs.
good evening, I want to leave my review about the laying hen bi 1 bi 2 incubator, I have many different incubators at home, round, small-sized ones and an automatic poultry yard, they always let me down, only square laying hen incubators help me out in the future, I plan to replace all my incubators with the bi2 laying hen
I would like to know the brand of digital thermostat for a laying hen incubator for 77 eggs, with parameters t, humidity, egg turning, count. days, 220/12V, backlight, fan, when the 220V power is turned off, automatically switches to 12V. And the wiring diagram is in Russian.
