kitchen waste bio-organic fertilizer refers to collect the living waste and kitchen waste first, then make them into bio-organic fertilizer after fermentation compost and other post treatment processing. The organic fertilizer has rich nutrition which could improve the soil and solving the soil hardening problem by using fertilizer. It can also improve physical and chemical properties of soil and increase the soil ability of keeping water, fertility keeping and fertilizer supply.
Jiangsu Liangyou Zhengda Co., Ltd is specialized in manufacturing organic fertilizer pellet production machinery, we can supply customer: bio-organic fertilizer pellet production line which take animal manure (mainly chicken manure, pig manure, cattle manure, sheep manure and etc.,) as raw material, bio-organic fertilizer pellet production line which take urban kitchen waste as raw material, bio-organic fertilizer pellet production line which take urban living waste as raw material. FDSP will customize kinds of complete project solutions to meet customers' different needs.
Now we take the case of 2-3t/h urban kitchen waste bio-organic fertilizer production line, make introduction based on process diagram and each process as follows:
urban kitchen waste refers to the solid waste produced from food during the production, transportation, distribution and consumption, the main physicochemical property is with high moisture content, high organics content, high fat and salt content, kinds trace element content, easy to rotten and smelly.
Flow process introduction:
single FZLH508 urban kitchen waste bio-organic fertilizer production line is to ferment and compost the urban kitchen waste, after drying process, the material will go into the workshop for grinding , mixing, pelleting, cooling and bagging process, finally into bio-organic fertilizer, this project could produce 2tons organic fertilizer pellet per hour, the total power of machine is about 380kw, the occupy of main work is 2400m2 including raw material warehouse and finished product warehouse, the whole line is characterized by compact design and reasonable structure, and satisfied by environment protection requirements, meanwhile it can be directed to customers design.
Technological process chart:
Fermentation and compost process ---pre-treatment process---grinding process--- mixing process--pelleting and bagging process
Technological characteristics and introductions:
Fermentation and compost process :
pile the blended ingredient up to strip which is 1.5-2meters wide, 0.8-1.2meters high and length is no less than 3meters, during the fermentation, be careful with suitable oxygen supply and turning.
Compost equipment: LYFP-3, power: 19.5kw, output 300 m3/h.
Use the dedicated organic fertilizer chain grinder break up the fermented raw material, then remove the impurities from the raw materials, including big wood blocks, stones, blocked materials by drum precleaner, after that use the drum dryer drying raw materials to approx. 20%.
Drying equipment: LYHG1.6*15, drum diameter 1.6m, length 15m, power 8kw, output 3-3.5t/h
the material will be transported to grinder for grinding, iron-remover will be equipped before grinder.
grinding equipment: FFSP66×60，55kw, designed output 3-4T/H.
The bacteria which added through micro elements adding hopper can be mixed with raw material in mixer, after evenly mixed, the mixture will enter into next process.
Mixer: SDHJ1, power 15kw, output: 1m3/batch
adopt dedicated organic fertilizer ring die pellet mill with the suitable linear velocity, high accuracy gear driven pellet mill has higher driving efficiency, ring die is quick-loaded clamp type.
pellet mill: FZLH508 with 132kw, output 3-4t/h
Cooling and packing process:
choose flip type cooler which can prevent the broken of pellets. vibration screener under the cooler could sifting the un-shaped powder. According to the customer's local sales needs, the appropriate packing scale is selected for customer to sell products more easily. Packing specification: 20-50kg/bag.
cooler: FKLB2.5, cooling chamber volume 2.5m3, output 3-4t/h
Packing equipment: SDBLY-PD belt packing scale, packing range: 20-50kg/ bag, 6-8 bag/min.
Compared with other wastes, urban kitchen waste is with high moisture content, high organics content, high fat and salt content, and easy to rotten. So landfill of kitchen wastes has the problem of land wasting, producing foul gas and percolate. The bio-organic fertilizer production can turn the wastes into treasure which can not only produce economic benefits, but also protect the environment
