Pig manure organic fertilizer production line equipment
Introduction of pig manure organic fertilizer production line:
In the pig manure organic fertilizer production line, there are two
steps to process commercial organic fertilizer: the early
fermentation and treatment part and the deep processing granulation
part. Pig manure organic fertilizer granule production line is
mainly equipped with the following equipment: tipper, crusher,
batching machine, mixer, granulator, dryer, cooler, screening
machine, coating machine, automatic packer. The general production
steps are as follows: raw material fermentation, raw material
mixing, raw material granulation, particle drying, particle
cooling, particle grading, finished product coating, and finished
product packaging.
Pig manure organic fertilizer fermentation:
1. Feed preparation and adding bacteria: the pig manure organic
fertilizer production line should prepare the manure to be
fermented, the better is fresh pig manure (the fermentation effect
of fresh manure is better than that of old manure), for example,
about 1 ton of fresh pig manure plus 0.25 kg pig manure
fermentation agent. The pig manure starter should be mixed with
rice bran (or corn flour, wheat bran) in the ratio of 1:5-10.
2. Construction of pig manure pile: the prepared pig manure should
be built while spreading bacteria. The pile height and volume
should not be too low or too small. Requirements: pile height 1.5-2
m, width 2 m, length unlimited.
3. Adjust moisture. The moisture content of fermented pig manure
should be controlled at 40-65%. Moisture judgment: hold a handful
of pig manure tightly, see the watermark but do not drip, and
disperse immediately after landing. Less water, slow fermentation,
more water, poor ventilation, will also lead to "spoilage bacteria"
work and producing odor, therefore, we must grasp the moisture
content.
4. Startup the temperature. The start-up temperature of organic
fertilizer production should be above 15 ℃ (it can be operated in
four seasons, not affected by seasons, and should be fermented
indoors or in the greenhouse as far as possible in winter), and the
fermentation temperature should be controlled below 70-75 ℃.
5. Mix well and ventilate. Pig manure starter needs good
(consumption) oxygen fermentation, therefore, in the process of
preparation, oxygen supply measures should be increased, and it is
appropriate to mix well, turn frequently, and ventilate. Otherwise,
it will lead to anaerobic fermentation and produce odor, which will
affect the effect of fertilizer.
6. The fermentation was completed. Generally, after 48 hours of pig
manure accumulation, the temperature rises to 50-60 ℃, and it can
reach 65 ℃ or above on the third day. Under this high temperature,
it needs to be overturned once. Generally, the fermentation process
will have two times of high temperature above 65 ℃. The
fermentation can be completed after two times of overturning, and
the fermentation can be completed within one week. The material was
dark brown, and the temperature began to drop to normal
temperature, indicating that the fermentation was completed.
The benefits of pig manure organic fertilizer:
Pig manure organic fertilizer has complete nutrition and a
long-term fertilizer effect. Pig manure organic fertilizer
production not only contains amino acids, protein, sugar, and other
organic nutrients but also contains n, P, K, medium elements (Ca,
Mg, s, etc.), and trace elements (Fe, Mn, Cu, Zn, etc.) that are
beneficial to crop growth. On the premise of increasing the organic
matter, nitrogen, phosphorus, potassium, calcium, magnesium, and
various trace elements in the soil, compared with chemical
fertilizer, organic fertilizer is slowly humic decomposition in the
soil, and the fertilizer effect is more lasting.
The process flow of pig manure organic fertilizer production line
is as follows:
① Raw material fermentation - ② automatic batching system with
scale - ③ crushing and mixing - ④ disc granulation, drum
granulation, extrusion granulation - ⑤ dryer drying of organic
fertilizer particles - ⑥ cooling machine cooling of organic
fertilizer particles - ⑦ Screening machine Screening qualified
organic fertilizer particles - ⑧ Coating machine coating particles,
smoother - ⑨ Automatic filling of organic fertilizer particles by
packaging scale - ⑩ Sealing.
