Definition of urban kitchen waste bio-organic fertilizer production line:

Kitchen waste bio-organic fertilizer refers to the collection of household garbage and kitchen waste first,

after fermentation composting and other post-treatment, to make bio-organic fertilizer. Organic fertilizer is rich in nutrients,

can improve the soil, the use of fertilizer to solve the problem of soil hardening.

It can also improve the physical and chemical properties of soil and improve the capacity of soil water retention, fertilizer retention, and fertilizer supply.

Raw material:  

Urban kitchen waste refers to solid waste generated in the process of food production, transportation, distribution, and consumption.

Its main physical and chemical properties include high water content, high organic content, high fat and salt content, various trace elements, and perishable 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 the 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 the machine is about 380kw,

the occupy of main work is 2400m²including raw material warehouse and finished product warehouse,

the whole line is characterized by a compact design and reasonable structure,

and satisfied by environment protection requirements, meanwhile, it can be directed to customers’ design.

Process flow:  

Fermentation and composting process – pretreatment process – grinding process – mixing process – granulation bagging process

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.

Pre-treatment process:

Use the dedicated organic fertilizer chain grinder to break up the fermented raw material,

then remove the impurities from the raw materials, including big wood blocks, stones, blocked materials by drum precleaner,

that use the drum dryer drying raw materials to approx. 20%.

Grinding process:

the material will be transported to the grinder for grinding, iron-remover will be equipped before the grinder.

Mixing process:

The bacteria which added through microelements adding hopper can be mixed with raw material in the mixer,

after evenly mixing, the mixture will enter into the next process.

Pelleting process:

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.

Cooling and packing process:

choose flip-type cooler which can prevent the broken of pellets.

vibration screener under the cooler could sift the un-shaped powder.

According to the customer’s local sales needs, the appropriate packing scale is selected for customers to sell products more easily.

Packing specification: 20-50kg/bag.
