Description
Technical field
The present invention relates to a kind of grain mold proof storage facilities, belong to foodstuff preservation equipment technical field.
Background technology
Bread is the staff of life, and food is first with rice.Rice growing area accounts about the 27.5% of the total sown area of China's grain, year
About 1.85 hundred million tons of yield.The agricultural product most as yield per unit area highest and total output, the whole nation have more than 65%
Population is using it as staple food.Since nearest 10 years, 85% or more rice is consumed as grain ration.The minor variations of rice supply and demand
It all may result in provision price or even entire society's price fluctuation, rice safety be directly related to national food security.Once
The production of rice and storage go wrong, it will largely influence the daily life of the people.
The grain yield in China has occupied the first in the world, but the integral status of food storage, especially accounts for national storage
The rural area of grain total amount 70%, grain storage loss late and international still gap are notable.The grain post-harvest loss rate of the developed countries such as America and Europe
Less than 3%, in China rural area, this data is but up to surprising 8%, and year, loss amount was even more more than 20,000,000,000 kilograms.Basic reason master
Have at 3 points：First, the scientific knowledge scarcity and technological means of farm storage are weak, and traditional the mean of storing grain lacks effective improvement
And guidance；Second, level of farming mechanization is low, and scattered storage is without concentrating drying after grain harvest；Third, the storage of current grain
Tibetan the relevant technologies ease for use is poor, and equipment cost is higher, and the quality and technical ability of peasant are less than advanced country's standard.
The factor of grain loss is also various during practical grain storage.It is generally acknowledged that including mainly exhaling for grain itself
Suction effect is lost, grain ageing caused by microorganism goes mouldy, the insect pest of the moisture loss in storage and grain.
China's mould proof means of traditional rice have ventilation, ted, is airing, stifling etc..Storage more advanced at present in the world
Tibetan technology has：Dampness elimination, controlled atmosphere and physical condition processing etc..Although biological film-coating antistaling agent is that the green grain storage method of representative is current
Still there is limitation, but is trend of the times.
The mould proof basic ideas of traditional rice are the humidity and temperature by controlling storage ambient, so that Environmental Law is met mould
The growth conditions of the microorganisms such as bacterium.Or the microorganism in grain is killed using physics and chemical method, to inhibit to go mouldy.It passes
System method is easy to operate but effect is unstable, and be easy to cause medicament residue.
Modern rice mould-proofing new method also faces problems in the world.The high energy consumption of physical sterilizer, Gao Cheng
Originally its large-scale application is limited；Air conditioning technology lacks cheap packaging material at present；With the fresh-keeping life for representative of fruit and vegetable coating
Although object anti-mildew fresh-keeping technology has made some progress, but overall also in fundamental research and explorative research stage.In addition to
Green grain storage technology itself it is not perfect, another aspect China agricultural is generally also in developing stage, relative to western countries
For market it is immature, the development prospect of green grain storage receives also therefore to a certain extent larger restriction.
Invention content
Present invention mainly solves the technical issues of：It is excessively high for existing grain storage equipment grain reservation internal heat, and be not easy
Distributing causes mouldy inside grain, and when being dried, is not easy the problems such as dry inside grain, the present invention provides a kind of grains
Eat mould-proofing device.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention：
A kind of grain mold proof storage facilities, including tank body, the tank interior are provided with vacuum layer, are provided on the inside of vacuum layer
Heat exchange pipeline and air refreshing tube, heat exchange pipeline connect the heat exchange ventilation device of tank interior with air refreshing tube, and exchange heat ventilation device
Centre is provided with temperature humidity inductor, and is divided into two layers, and upper layer is heat exchange layer, is internally provided with heat exchange coil, and lower layer is logical
Stratification of wind is internally provided with ventilation hole, and air heating sterilizing unit is provided with above tank body and heat-exchanger rig is managed with ventilation respectively
Road is connected with heat exchange pipeline, and discharge duct is arranged above tank interior, and discharge duct is connected with exhaust fan.
A kind of application process of grain mold proof storage facilities is：By foodstuff preservation in tank body, vacuum layer is used for tank body
Inside is kept the temperature, and temperature humidity inductor is detected tank interior, when detecting that temperature is higher than 20 DEG C, system control
Heat-exchanger rig, heat-exchanger rig convey cooling material into heat exchange pipeline, and cooling material enters through heat exchange pipeline inside heat exchange layer
In heat exchange coil, temperature is reduced with heat exchange is carried out inside grain, when detecting that temperature is less than 15 DEG C, control system controls air draft
Fan outside air draft, tank interior generates negative pressure, air heat sterilizing unit by air heat along air refreshing tube enter ventilating layer to
Grain delivered inside hot-air improves internal temperature.
The tank interior set temperature is 15 ~ 20 DEG C.
The heat exchange ventilation device is provided with three groups in tank interior, is arranged above and below.
The heat exchange coil is made of copper.
The beneficial effects of the invention are as follows：
（1）Three groups of heat exchange ventilation devices are provided in tank interior in the present invention, after food storage is in tank interior, ventilation is changed
Thermal is coated over inside grain, and temperature and humidity when foodstuff preservation inside grain can be higher than external temperature and humidity,
Previous mode is directly adjusted external temperature humidity, and change to grain inside does not cause still to will produce inside grain very much
Signs of Mould is arranged by the ventilation device that will exchange heat inside grain in of the invention, from internal detection and the temperature of change grain
Humidity is spent, mould-proofing effectively has been carried out to grain, has improved the quality of foodstuff preservation.
Heat exchange ventilation device is provided in the present invention inside grain, logical heat exchange ventilation device is divided into two layers, and one layer is used for
One layer of heat exchange can not only adjust the temperature inside grain, but also can adjust the humidity inside grain, and ventilating layer connects for divulging information
Connect air heating sterilizing unit, tank interior will be transported to again after the heated killing of bacterium in air, prevented mould into
Enter, improves the quality of foodstuff preservation.
