Fruit Tree Branch Disposal

Organic fertilizer production equipment is widely used in solid organic waste fermentation treatment, such as livestock and poultry manure, straw, fruit branches, waste tree branches of urban landscape greening, tailings, food factory waste, etc. The biggest advantage of this equipment is that the whole process is mechanized operation, the compost matures quickly, the fermentation cycle is short, 15-18 days can become high-quality organic fertilizer.

Fresh livestock and poultry manure (cow manure, chicken manure, pig manure) (excluding other impurities) was mixed with appropriate ratios of supplementary materials (straw, bran, etc.) (adjusting moisture content and C_N of the stockpile). These materials were evenly mixed by forklift truck and stacked in strips (moisture content is about 50%-60%) with a width of 2.8-3.0 meters and a height of 1.2-1.4 meters.

The temperature and moisture of the material were measured at 8:30 a.m. and 4:30 p.m. every day after the material was stacked, and the accurately recorded temperature and moisture curves were made. The basis for next working procedure (flipping).

According to the results of temperature measurement, the upper layer and the surface should be turned into the bottom and the central part. Turning over should be meticulous and thorough in order to crush, increase oxygen, promote microbial reproduction and volatilize water. The evaporation of moisture is increased by continuous high temperature and (7-10 times) overturning to ensure that the moisture content of the stack is below 45%.

After 15-20 days of stacking fermentation maturation, the stockpiles were placed in the semi-finished product warehouse and stacked for 15-20 days. After moisture volatilization reached the national standard, the stockpiles were crushed. Before packaging, semi-finished products are refined by screening machine, and impurities are removed by screening. The standard is less than or equal to 2.0.

According to NY525-2012, the water content, pH value, organic matter content and total nutrient (nitrogen + phosphorus pentoxide + potassium oxide) content of the finished product after sieving were determined to ensure the product quality.

It is packed by automatic packaging machine according to 40 kg plus 0.5 kg per bag (packing label according to GB 18382), and stored in a cool and dry place after packaging. The packaged products should be sampled every two months for weighing inspection in order to prevent weight loss.
