ChangFang incubation of the design

A plane is hatching room layout design.
Second, it is air conditioning system design.
This is not entirely separate from two aspects, unrelated. In the design process, also is the overall consideration must take these two aspects as a whole to consider. Firstly, according to your requirements shall be determined the hatch, advance the hatch equipment purchase quantity and types. If large scale, eggs, the stable source is best choice hatch equipment. Conversely, medium and small hatch machine. Type and quantity, also means each function of incubator between structure and size of course (should consider the expansion of the scale of production, left patulous space). Because of the small, narrow space, can cause inconvenience to production process, production efficiency. And then will cause unnecessary waste and the initial investment cost is high in operation. Hatch room should include the following functions: the dressing room, shower room, eggs, duty, fumigation supply, hatch, and a young, wash hair, deposit between young etc. Each function should take place between the warehousing, disinfection, storage, and hatching, a young, rinse, young, the sequence of the working process flow and anti-epidemic work. Hatch room should pay special attention to the dirty and net area between. Each channel, such as setting belt between shall set up disinfection tank. The shower room is very necessary, it is often ignored by many factories. The area and place egg library in proportion to the quantity. Hatch room should be mounted on the ceiling of the room temperature, the ceiling. Disinfection should add certain air exhaust fan, ensure more rapidly after disinfection of gas discharge. Out.
Secondly, hatch room ventilation design is not overlooked factors, the rational design of the hatch rates for the quality has very big effect. Whether to the young or between hatching, between the gas discharge hall, at the same time to the fresh air in the world must have entered the hall to supplement. If the number of machine, the machine can hatch waste to the ceiling, then by fan, but a young collective of waste must by machine emitted exhaust pipe, not to the ceiling, If the machine is smaller, hatch machine of gas can be directly by exhaust pipe out.
In the design of hatch room ventilation system, want to consider to hatch out from between and among young emissions are not be inhaled by hatch indoor, especially the young room emissions may be more to hatch. Outside in the fresh air to enter through the air blower, smoke or the land into the window. Summer can consider installing cooling equipment, in order to reduce the temperature outside smoke from the air temperature, but no matter how northern winter indoor heating facility, it must be installed to assure indoor temperature. In case, if the machine machine hatch room number, can consider to 6 meters, building span can use the old building, but only one row machine, If the number of machines, can consider to build span, it is 9 meters, can put two rows of economic machine, If the machine number, suggest building span for 9 meters, but still to build more incubator, separated by wallboard, we don't recommend one hall two row above, because this machine for ventilation and temperature control in the summer.
The above is the construction of large, medium-sized hatchery. If the amount is hatched, more than tens of thousands of small hatchery should use of existing homes can be modified.

7. Comprehensive inspection of each system control function.
Four, for a long time when the machine without maintenance
In a long time before the machine without suspended on heating drying machine, must be humidifying birdbath, the water clean, dry run to wash with butter, protected from rust. It is very important. You decide you don't want a machine, but not by the method to maintain it, so when you want to use it again next time, it might not work, failure.
Five, the use of attention
1 hatch equipment operation process, must observe machine working state, every 1 ~ 2 hours once observed, and make record, abnormal condition promptly. Especially door machine table temperature and temperature difference have changed, if there is a change to timely according to requirements.
2 after control is very important, should check whether appropriate, practical set position are consistent position.
3 observation records, egg dish over egg is around two inclined position alternately.
4 egg dish push pull must in a horizontal position.
5 if encountered during incubation power, should be the power switch off the machine, until after the machine to work properly. Use generator power, should pay attention to its output voltage stability and observe all motor rotation direction correctly (self-provided generator and power lines in between electric should change), Blackout machine doesn't work should open the door to hatch machine.
6 after hatching, chicks are pecked during the hours during the shell is strictly prohibited use formalin fumigated. Some of the sales of humidity sensor has corrosion disinfectant, not in use in hatch. 7. Please read carefully the operating instructions and according to execute.

A, selectin management

The management should be ZhongJiChang 1.1 protein
ZhongJiChang should collect protein, general advice in collecting, four times to reduce pollution and damage. Raised in collecting selectin administrator shall promptly after two hours, then immediately soildisinfectant fumigated will place to egg. Send egg process to prevent selectin summer were exposed, drench, winter antifreeze.

The storage conditions with 1.2 protein
The protein in the storage temperature keeps 13 degrees - 200c.best scope, humidity must reach 70%. For the young chicken, its a little early protein, egg, protein, thick thick long storage time. But to mid size, eggshell, selectin thickness, protein is the best, the storage time should be short. Later on, place a great place, thin thin shells, protein, storage time should be shorter. Listed below are suggested and storage conditions and time. If the need for hatching production and prolong storage time, storage temperature should be lowered, save time accordingly should not be more than a week, otherwise the hatch rates decreased obviously, and duration of protein is hardly beyond 15 days of incubation.

1 and 3 protein

(1) pollution eggs, eggs, breaking eggs must eliminate crack, otherwise will form the hatching smelly egg and pollution other place explosive, the loss outweights the gain.
(2) thin shells eliminate sediment eggs, eggs and deformity eggs, protein shell thickness in 0.32 mm around the best.
(3) general JiZhong tuber heavy should be in 50-65g, selectin of index in 72-76 percent.
(4) protein in hatch egg dish should head up. For different weeks in place to chicken, storage and distinguish the mercury in order to get the best treated separately, hatch.
(5) place of work is very important, besides disinfection disinfection, once in the hen egg in the hatchery sorting personnel should choose after the second after disinfection disinfection, push into the egg libraries are stored. Launched by the eggs in place even before the hatch the third disinfection, to ensure the hatch process not polluted place. At present the main method is formaldehyde disinfection method which fumigation concentration 42ml (three times, fumigating MaLinJia 21 grams/M3 potassium permanganate fumigation) in 20 minutes, fumigation temperature, humidity is above 20c for 60-80% RH, fumigation immediately after completion, fumigating container lifts exhaust fan open the disinfection of gases. Also useful for spraying method, if undertake alexipharmic place with the latter's new jie destroy spray or 1% hydrogen peroxide, 0.5% of peracetic acid and amino 175ppm season for spraying, When a disinfectant spray surface should be covered place.
(6) eggs in the library must be used water disinfection tank (like the latter's new jie destroy solution). Protein in the egg repository must be placed at 30 centimeters, is apart from wall to ensure uniform temperature.
(7) should be located between fumigated eggs, disinfection of library in the largest slightly over every disinfection, and set aside egg quantity size can be placed space of disinfection device. Disinfection room must set per cubic meters of exhaust fan, exhaust fan flow space than the 20m3 / points, with quick smoke net fumigation gas.

Second, the temperature and humidity control

2.1 temperature setting

Temperature is the most fundamental condition, artificial incubation temperature setting should be based on the needs of the development of embryos, because of differences, hatch chicken breed different mechanisms and equipment conditions, the changes in temperature incubator, but is basically in diverse 37.2 - between change (augusts advocated by temperature incubator in data 37.80c, the change of0.1 conservative, so that we must reach the best effect of hatch. Practice has proved that the large in hatch production, variable temperature incubator is obviously superior to hatch, because the constant temperature incubator is most suitable for embryonic development needs.
For variable temperature incubator, its temperature setting are low, when after the former high temperature environment for 22-27 degrees Celsius, suggest the whole batch hatching variable temperature incubator of optimal temperature is: 1-3 days for 38.00 degrees Celsius, 4-7 days for 37.90 degrees Celsius, 8-12 days for 37.80 degrees Celsius, 13-15 days for 37.70 degrees Celsius, 16-18 days for 37.60 degrees Celsius, the young for 37.00-37.20 degrees.
But, in the environment of constant temperature incubator for 20-27 degrees Celsius temperature can be set for the conditions 37.80 degrees Celsius. A young 37.20 degrees Celsius temperature can be set in.
The temperature setting scheme is a universally applicable principle, in actual set to adjust, according to the circumstance in adjusting to pay attention to the following questions:

(1) check whether appropriate, the temperature can meet the requirements of the best way is to observe embryonic development situation, also is ShiWen tyres. This needs the experience accumulated and precipitation. Generally, in the hatch full 10 days after 17 days due to 90% of the embryonic development and harass and FengMen, experienced available measures according to check and control egg with temperature.
(2) in different seasons and different environmental temperature, temperature must adjust incubation temperature environment generally, every high or low temperatures, set 2 degrees or 0.1 °. Reduce
(3) of different weeks in the hatch chicken selectin of temperature, humidity required differences, therefore, had better be the hatch of the same place into the same hatch machine, with the chicken will just opened in the protein in hatch temperature increase 0.1 degrees Celsius.
(4) during the incubation of the equipment to regular temperature, the door is usually watch (standard thermometer), compared to ensure accurate temperature with calibration.
(5) for large fowl-run, had better use roadway hatch production, and the small scale of production in hatch, compared with appropriate box sets cabinet unit may adopt partial hatching of incubation. "Margin" brand of instruction, hatch equipment provides let egg quantity 25200 above case machine partial hatch. For 19200 or 16800 let quantity box machines egg every 10 days into two cars, even partial hatching to using thermostatic hatch ShiWen scheme, also can obtain very good hatch. To save electricity and can reduce the production cost. Note: there is no egg in the egg to always filled with empty parking lots of eggs, or eggs will influence car filled in temperature field.

(6) place beforehand

From the eggs of low protein library environment, unfavorable immediately after hatching, partial hatching hatching, especially important, directly into the cold eggs hatch embryo destroys the ambient temperature, the stability of the eggs hatch machine of high humidity and air in cold water condenses into small eggs, make its "sweat," bring pollution.

Protein is preheated time 6-8 hours, the preheated temperature for 24-26c, no specific areas of the manufacturer, also preheat hatch hall in preheated. Preheat when must control environment humidity, don't let selectin "sweat."

Under the table for protein not "sweat" environment humidity is checked.

2.2 humidity control
During the incubation effect of humidity is within the moisture loss adjusting protein and protein, to ensure control of weight-lost embryonic development and normal good gas exchange (CO2 emissions of O2 and inhaled), Maintain proper hatch machines also make the air humidity with good thermal conductivity, heat exchange. Practice has proved to the range of embryo humidity is wider, don't like temperature, protein in 1-19 days of incubation process weightlessness rate reached to 11.5% 13% get high quality chicks.

When the hatch indoor humidity can keep in 50-60% RH, hatch process in 55-60% humidity is set to ensure selectin of weightlessness. If the environment variable low or high humidity, set to improve or humidity accordingly. For in just opened in place and near the chicken chicken out in protein can be set low humidity of hatch, moisture loss. A young machine, high humidity should not just fell from the lower plate can lower at 65%, actual use RH by 70% RH advisable.

Incubation devices humidity is moisture sensor measurements, the value will regularly and accurate wet thermometer check value, if not, the adjustment that measurement accuracy. On the market sell alcohol wet precision is poor, challenge the best buy mercury thermometer, if the user buys wet, as long as I have difficulty to phone companies, which can receive a satisfactory answer.

Three eggs hatch, is one of the important conditions

Timing can make double eggs hatch change in position embryo inside machine is heated evenly, can prevent the embryo adhesion, promote development. Information and practical experience shows that every hour or two hours every hatch the eggs over time, without any difference, in order to reduce the abrasion and save energy, time had better choose egg for 2 hours once, but the type of machine, to ensure the hatch, mostly using uniform heat selectin once an hour.

15 days after the embryonic development can not turn eggs, but the type of hatch machine requires must not turn eggs, but the development of egg dish bracket on, be helpful for air circulation and heat exchange.

Turn insufficient number of eggs or don't turn eggs for embryonic development has great influence, can cause yolk sac sticky shell and allantoic fold, outside the allantoic sticky remaining egg, hatch rates drop. So in use should pay attention to record the movements over time, prevent eggs does not turn eggs or inadequate number of eggs.

Four, ventilated take a breath

Ventilation to hatch production is crucial, it often is not recognized. Many small and medium-sized hatchery, even some large hatchery management personnel to understand the importance of ventilation, and measures taken for the production with the improper damage. The aim is for ventilation in different regions provide incubator hall, fresh, clean air exhaust air pollution, CO2 and downy, etc.

Fresh air is 21% oxygen, CO2 content for the production of 0.04%, hatch is very appropriate. Therefore in the temperature and humidity control can be stable in the premise, near the value to be set to larger position, being in hatch to 10 days, we should pay more attention to hatch machine ventilated take a breath.

How to guarantee good ventilation?

(1) hatch hall into
Generally hatch machine from hatching hall, so fresh air to breathe in the fresh air into the hatch room amount must be greater than the subsystem for maximum incubation machine.

(2) hatch hall, hatch machine exhaust
The main hall of hatch exhaust machine or give cheeper is hatching machine exhaust. And the young hatch of the exhaust pipe must have the hatch from outside the hall and ensure that won't breathe in hatch hall. If each hatch machine each outlet (or a young machine) installed separately from the exhaust pipe directly outdoor and only one straight pipe road, the total length of no more than 3-4 meters, can not add air blower, had better add air fan ventilation to ensure sufficient. If use pipes more hatch machine tier exhaust spare incubator, each row in hatch equipment to add blade duct branch to control emissions, and air blower shall choose pneumatic bigger fan, and to ensure diameter is big enough.

Except special points are not directly, exhaust hood in hatch machine (out) the outlet of young, otherwise will influence the hatch machine (out) of the enclosure is young, which affect the incubation temperature distribution. Exhaust outlet in hatch and joint of machine made a trumpet, should the lower edge of the trumpet, and the upper edge of the outlet 5cm apart. "Margin" brand of fuzzy computer hatch equipment outlet design, user to exhaust vent pipe can be directly in the hatch cover the vent.

Five, and the young

In time to 5.1 attention environmental temperature must not too low (25 degrees Celsius) and the attention is seasonable cleared smelly egg, eggs, and fell dead sperm to light, dish of movement and quickly, not allowed to touch broken into embryos eggs, eggs and embryos from young to the basket, and even to smooth out into the car, ensure young into a young machine won't squeeze into the egg, otherwise cause uneven heat caused by a young time is uneven.

In the process of hatch the eggs and embryos temperature environment, so there is always some difference in the time with the best will place in hatch machine in the location of a change in order to promote embryonic development. Evenly Operating methods refer to hatch equipment specifications.

After 36 hours dish 5.2 fall can formalin evaporation disinfection, proved with 1 times formalin evaporation quantity of disinfection, can achieve very good result. The method is: use 14ml/m3, MaLinDui amount of shallow water temperature in the basin, the two sides of the young fan put a car in the basin, control its just 12 hours after evaporation, then put in two, even before closing picked young.

Using this method can make chickling disinfection and very beautiful, downy become yellow, and can effectively kill the bacteria existing within the machine, prevention of infection, and hilum to stimulate the respiratory cause.
