Description
Technical field
The present invention relates to a kind of fertilizer moulding, drying installation, especially a kind of bio-feritlizer moulding, dehumidification system.
Background technology
Microorganism (bacterium) fertilizer, is called for short bacterial manure, claims again microbial inoculant.It is (manually to train system) by fermentation by the microorganism with special usefulness to form, contain a large amount of beneficial microorganisms, after being manured into soil, or nitrogen in can fixed air, or nutrient in can activating soil, improve the nutrient environment of plant, or in the vital movement process of microorganism, produce active substance, the specified microorganisms goods of stimulating plant growth.As the new-type fertilizer microbial fertilizer of production pollution-free food production data, become Ministry of Agriculture's emphasis and promoted product.But with high content of technology due to microbial fertilizer, production difficulty is large, and in China market, high-quality product is also little.Tool authoritative department is estimated: in 5 years of future, the annual requirement of microbial fertilizer will reach 30% of fertilizer amount, market capacity will reach forty-two million ton, and 3,000,000 tons of present year output less thaies of China's microbial fertilizer, can not meet the needs in market far away.
According to biological organic fertilizer standard NY884-2012(biological organic fertilizer standard), requirement living bacteria count >=0.2 hundred million/gram, organic >=40%, according to the requirement of the composite microbiological fertilizer industry standard NY/T798-2004 of the Ministry of Agriculture, living bacteria count is the key technical indexes of this product, and living bacteria count amount must be greater than 2,000 ten thousand/gram, total (N+P of supporting
2o
5+ K
2o) must be greater than 6%.Visible living bacteria count is the important indicator of the quality product of biological organic fertilizer and composite microbiological fertilizer, and living bacteria count is not up to standard, and quality product just can not be guaranteed, and what reflect is that effect is unstable.The factor that affects biological fertilizer products fertilizer efficiency mainly contains: 1, living bacteria count, there is no enough effective bacterium, and the bio-bacterial manure of being just far from being, our moulding, dehumidification system have ensured viable count.2, moisture content index, degree of drying affects bacterial classification survival time, our shaping and drying System Assurance suitable moisture content index.3, composition of raw materials, good formula can ensure effective bacterium quantity, again can be for plant growth provides more nutrition, certainly, our shaping and drying system allows these composition of raw materials can not destroy, change because of process for processing exactly, thereby ensures product effect.
