1, this technology is added to the microorganism species of high activity, during the fermentation high temperature resistant, can be in fast decoupled raw material
Organic substance, existing compost production then rely on the microorganism in natural environment to ferment, and microbial activity is low, fermentation process consumption
The time taken is longer, and decomposed insufficient, and the case where leading to rotten of burn seedlings happens occasionally.
2, this technology is supported by mechanical slot type turning, ventilation, fermentation process existing compost hair for aerobic hot fermentation
Organic matter is largely decomposed into heat, carbon dioxide, water during ferment, and a large amount of organic matter is wasted.It is remaining in compost to have
Fall ill bacterium, worm's ovum is not killed, and fertilising can cause a large amount of diseases of crop, insect pest.Aerobic high-heat fermentation simultaneously not will produce
A large amount of methane, ammonia etc., cause environmental pollution and the wasting of resources.
Invention content
The technical problems to be solved by the invention（Goal of the invention）
1, used the component content of raw material, addition correspondence that can decompose the microorganism species of these ingredients, reach solution according to compost
The technical problem that certainly fermentation process is slow and fermentation is insufficient；
2, the organic matter of waste material can be oriented efficient humification by this technology using dedicated microbial bacteria, be converted into biology
Humic acid promotes Soil Microorganism breeding, accelerates soil mineralization, increases the absorbable nutrient utilized；
3, it is fermented using mechanical chain formula turning oxygen, the process for generating anaerobic fermentation in fermentation process is avoided, by aerobic
Fermentation reduces the generation of organic matter depletion and secondary pollution.
Complete technical solution provided by the invention（Scheme of the invention）
This technology uses high-temperature aerobic fermentation, and fermentation decomposition is carried out using active microorganism, has fermenting speed fast, decomposed degree
Feature high, production efficiency is high, the content of organic matter reach 60% or more, and moisture content is less than 30%, content of humic acid be more than 25% with
On, microorganism species reach the standard of 0.2 hundred million/gram, are the novel microbial bacterial manure using the production of agricultural wastes resource.It is whole
A technological process can be divided into premix processing, hot fermentation, ripening, packing processes Four processes.
（1）Premix processing：Microbial fermentation bacterium and waste material excrement, bacteria residue etc. are proportionally mixed, coarse adjustment heap
Fertilizer moisture, carbon-nitrogen ratio, temperature can be gradually increasing after mixing, wait for hot fermentation processing.Proportionally using microbial inoculum and excrement
Mixture.Raw material mixture is also a process of production technology, belongs to pretreatment stage before fermentation.Pretreatment not only adjusts mixture
Moisture, C/N ratios, since this stage medium temperature flora is dominant bacteria, flora can expand rapidly, compost temperature is risen in advance
Height, temperature rise is very fast after entering fermentation tank.
（2）Hot fermentation：By the raw material after mixing with loading machine be sent into fermentation vat, pile fermentation heap, using wind turbine from
Fermentation vat bottom up forced ventilation, is supplied oxygen, while carrying out within 1 day or so turning, control fermentation temperature at 55 DEG C~65 DEG C,
Aerobic fermentation is carried out, this engineering one time fermentation period is 15 days, goes out a displacement semi-finished product into a displacement raw material daily.It will be pre-
Mixed mixing shovel enters fermentation tank and carries out fermentation calefaction, requires to carry out fermentation process according to harmless treatment, it is desirable that stack not
Higher than fermentation groove height.
A. fermentation place and equipment：Turning is carried out using mobile chain stack-turning machine, fermentation tank is 2.3 meters high, and length is equal
It is 60 meters, amounts to 15 displacements.Subsurface 20cm installs air blast aerating system between slot, is mated formation rear cover using pvc pipe drilling
20cm metallings, forced-ventilation are cooled down and are increased air capacity between fermentate.Air blast duration of ventilation is with products material, production
Season is different and is arranged.
B. temperature controls：There are mainly two types of measures for temperature control：When turning machine, second is that ventilating system.Turning machine is daily
A turning is carried out, temperature rise is to 60 DEG C or more behind third day.Ventilating system rises situation according to fermentation temperature, carries out artificial
Configuration switch is respectively 2 hours/3 hours, to increase the oxygen content amount of fermentation material.
C. moisture controls：Moisture control is going out slot mainly by carrying out moisture reduction in fermentation process when turning machine turning
Moisture content is reduced to 30% or less afterwards.Simultaneously in ventilation process, air takes away heat and moisture.
D. fermentation time：According to the length of fermentation tank, the daily turning of turning machine is primary, a mobile displacement, take side into
The pattern for expecting side discharging completes primary complete displacement from feed inlet to discharge port, that is, completes fermentation process, that is, 15 days
Fermentation time.Each season, there is also differences for fermentation time due to influenced by ambient temperature, such as fermented in summer high temperature season
Time can shorten 2-3 days.When less than 60 DEG C of fermentation temperatures and no longer rising, slowly decline, until when reaching environment temperature, hair
Ferment is completed.
（3）Ripening：Ageing stage refers to, after compost completes hot fermentation, as temperature reduces, and the micro- life of medium temperature
Object bacterium starts active a, process of second of fermentation of progress again.Ageing stacking is carried out to the material after fermentation, carries out two
Secondary fermentation.This stage, mesophilic micoorganism group can enliven, and fermentation is more abundant, and general digestion time is with 10 since temperature declines
It is preferred more than it.Ageing stage, which contributes to the organic matter decomposition of the difficult decomposition of comparison to be that humus and amino acid etc. are more stable, to be had
Machine substance, makes fertilizer efficiency greatly improve.General digestion time should be preferably 10 days or more time.It is aged area requirement aeration-drying,
And not by the external water pollution such as rainwater.And it is aged region and stacks and be distinguished with raw material, avoid secondary pollution.Due to old
After the completion of the change stage, microbial organic fertilizer i.e. can commercial package, therefore the outside contamination for reducing this stage is most important.
（4）Packing processes：Further ageing finished product is sieved, screens out impurity in fertilizer（Plastics, stone etc.）, screen out
It is dispensed after impurity, storage is for sale.Oversize returns to pulverizing process and carries out reuse or discarded.Finished product material refers to completing ageing
The finished product microbial organic fertilizer that stage can directly be dispensed.Generally require three turning, sieving, packaging links.
A. turning：Since during ageing, surface layer organic fertilizer moisture loss is very abundant, and middle and lower part is thicker due to stacking.Institute
To need to carry out part turning with forklift in advance, first, the lost moisture of temperature is reduced, second is that make organic fertilizer water content uniformity,
Reach the requirement that moisture content is less than 30%.
B. it is sieved：Organic fertilizer is shoveled and entered sieve apparatus into transmission device, sieve apparatus, which will screen out, excessively does not meet the miscellaneous of diameter
Matter, including plastics, stone, house refuse etc. do not meet the impurity of organic fertilizer ingredient.
C. it packs：After the completion of sieving, dispenses and packed on line.It is dispensed by product 25kg, the built-in product quality certification
Equal labels, last envelope complete packaging production.Product passes through hoist engine, is directly entered Freight Transport to client orchard or storehouse
Equal appointed places.
In conclusion entire technological process specifically include mixing (microbial inoculum, excrement pre-composition mix in proportion) → hot fermentation →
Temperature change observation → air blast, turning → ripening → sub-sieve → finished product → packaging → storage.
