Description
Technical field
The present invention relates to hatching technique technical fields, and in particular to a kind of production technology of low temperature convection current hatching.
Background technique
Incubator currently on the market mostly uses artificial incubation case, semi-automatic incubator, full-automatic incubator, but all consumes energy
Height, large labor intensity, hatching quality uniformity is poor, and hatching quality can also be further increased and is greatly lowered with energy consumption, but
Existing product is unable to reach.
Extensive hatching at present；Full-automatic incubator and semi-automatic incubator, 10080 pieces of duck's eggs of capacity, semi-automatic hatching
700 yuan of the energy consumption annual of every mouthful of case, 1000 yuan of energy consumption annual of every mouthful of full-automatic incubator or more, semi-automatic electricity incubator go out shell
Rate 90% or so.Full-automatic incubator hatching rate 92% or so.
Hatching is to be transformed into present artificial incubation from initial natural hatching, and artificial incubation experienced original bucket
Incubate, water is incubated, kerosene lamp, it is flat incubate, after a heatable brick bed is incubated etc., it is now relatively advanced to be also generally accepted, use semi-automatic
Incubator.
The rise of this industry, science and technology, information, transport are more and more flourishing, and competition is increasing, then it is thought that boiled water
Boiler, supplement of the steam boiler as supplying heat source reduce a part of cost of hatching, and then new problem produces, and water meets gold
Category can corrode, and result in for warm extremely uneven, and boiler is especially at night, to be extremely difficult to ideal temperature by manual control, caused
It is unstable in hatching quality.
Semi-automatic electricity incubator takes manner to combine, and is readily transported.The material of case uses laminate, foam, has body
Gently, warming superperformance.An aperture is respectively opened in the two sides center of case, and case opens two apertures.(hatching of breeding eggs from first day to
7th day is totally-enclosed), internal structure external structure, movable incubator tray, egg rack, axis, bracket, belt pulley, electronic relay, plug-in strip electricity
In the case, incubator tray is placed in egg rack, and bracket is mounted on egg rack two sides, i.e. case two sides for mechanical, electrical heat pipe, probe, fan, egg rack installation
Open the place of aperture, axis, one installation belt pulley of axis put on bracket, belt pulley is connected with case top motor, bracket, egg rack,
Axis, belt pulley, motor connect into an entirety, and the top that probe is placed in case interior angle is connected with case top electronic relay, case
Corner installs electric heating tube close to the place at angle under interior two wall, and a fan is respectively installed at axis both ends, and sink is arranged at bottom in case.
In the semi-automatic incubator that the ground such as Sichuan, Guangxi use now, (i.e. aperture is two to about 2.4 meters of two side length of case
Side) case is about 2.2 meters high, and it is about 2.2 meters wide, 7200 pieces of capacity goose egg, 9900 pieces of duck's egg, 11880 pieces of egg, incubator tray 60.
Semi-automatic incubator has been changed to three-dimensional hatching on the basis of previous hatching pattern, plane hatching, makes full use of
Space improves the output of average area, facilitates management.Semi-automatic incubator is by artificially controlling temperature in previous hatching pattern
Water, kerosene lamp, coal etc. have been changed to temperature automatically controlled electricity and have incubated, and make that operation is simple, while work has been used in internal structure
Dynamic egg rack, can manual control egg rack angle, for angle generally at 45 ° to 55 °, angle reaches 55 ° of history to terminate egg-turning,
Greatly reduce labor intensity.After semi-automatic supplying heat source is changed to electricity by original coal, kerosene lamp, air has also been purified, has been reduced
Pollution, but hatch cost and improve.There is also great shortcomings for semi-automatic electricity incubator: first it is understood that life is not from
Oxygen is opened, and in incubator, the density of egg is very big to need a large amount of oxygen, but there is no what in this respect for semi-automatic incubator
Capable measure only leans on two side opening or carrys out supplemental oxygen in bottom opening, it is clear that the ideal state of hatching is not achieved.Case opens
Hole has reached the certain effect of ventilation in case, however heat loss does not take the measures such as waste heat recycling and reusing with regard to big.It incubates
Change case and needs certain humidity, present semi-automatic incubator two sides or lower section aperture, top aperture, although having reached certain
Ventilation effect, but humidity is just not enough in case, then by the way of artificial supplementation, is sprayed water on time daily, without accurate
Dry and wet data, to also can not in time, fully keep the skin wet, and hatch humidity be by factors such as temperature, brooding times and
Variation, its demand moisture in entire hatching process be not it is unalterable, certainly daily spray water on time also just it is unscientific,
It is unable to reach ideal effect.The heat source of present semi-automatic incubator is electric heating tube, and heat-generating pipe is mostly installed at close to lower end
The position at four big angles, heat-generating pipe are radiation when work, and the temperature of itself is up to 500~600 DEG C, in order to make the temperature inside the box
Uniformly, use forced cooling, even if working under fan, table temperature also can at 300 DEG C or more, and heat-generating pipe heat transfer side
Formula is heat radiation, then by heat source egg temperature than other places egg Wen Yaogao, the position generally installed according to heat-generating pipe with
The layout of incubator tray, there are also the especially intermediate egg temperature of the egg of the general bottom in the position of temperature-sensitive system is relatively low, so even if
Under the action of adjusting disk, high/low temperature can not be also solved the problems, such as at all.Using high wind, the temperature inside the box may be uniform, but water loss
Bigger, energy consumption can be bigger.The reason of between above several respects, also constrains the quality of production of semi-automatic incubator significantly, hatching
Low when high when rate, seedling quality is good or bad, so that quantity, quality all not can guarantee.Semi-automatic incubator is in previous hatching side
Certain labour is saved on the basis of formula, but the angle of its egg rack needs manual operation, by 2 hours one time conversion angle,
It needs to operate within one day 12 times.Front we said that the temperature-difference in semi-automatic incubator is bigger, it is necessary to by manually adjusting disk
Mode overcome, it is general to adjust disk two times a day, can only increase than no tune disk quality, this is the method having no idea, institute
With from the intensity of labour, it also fails to labour's thorough liberation and comes out.
In addition, incubator, during production, the environment in case is not only suitble to the demand of each hatching egg, while being also suitble to various causes
The existence of germ, such as the most common mould, hatching egg will appear that constitution is weak, and build is small once infecting poult, and hair color is poor, dead
Rate is high, and hatching rate is low, and growth is slow etc., and the method that present semi-automatic incubator is taken is one time one disinfection, is entirely transporting
It can not also be sterilized with other measures during turning, so the probability of hatching egg infection is bigger, can not thoroughly guarantee the quality of hatching.
Fully automatic electric incubator although compensate for adjust disk, conversion angle, water spray, uneven humidity the disadvantages of, but hatch at
It originally is the 2 times or more of semi-automatic electric incubator, from poultry chick quality, the two has no difference.Heating system is all electrothermal tube
Radiation.Hatching bottleneck is not broken through.
Oxygen, hatching egg be all it is lived, in incubator, early period, demand oxygen was little, and especially to the later period, hatching egg is a large amount of
Need fresh oxygen.Electric incubator is radiation fever, in order to reduce energy consumption, by the way of incubator in fan case using recycling,
With regard to severe depletion of oxygen in case, since, without fresh air ventilation, the exhalation of hatching egg later period large quantity of exhaust gas, exhaust gas can not be arranged in the case in case
Out, hatching rate and poultry chick quality have been seriously affected.Temperature, electrothermal tube heating temperature are up to 600 degree, evaporate the moisture in air
Too fast, there is a serious shortage of moisture for the air in incubator, have serious influence to shell and quality is hatched.
