There are two important processes on an organic fertilizer production line, namely fermentation and composting process and organic fertilizer granulation process. These two represent the two stages of early processing and deep processing in organic fertilizer processing technology, respectively. These two stages of the process are as follows:

Fermentation and granulation process of organic fertilizer production line

The fermentation and maturation process of organic fertilizer production line is to use raw materials such as livestock and poultry manure to eliminate pests through trough, stack or tank fermentation. The granulation process is to process powdered organic fertilizer into spherical or columnar particles through granulation equipment.

Fermentation and maturation process

The organic fertilizer fermentation and maturation process involves using organic fertilizer raw materials such as livestock and poultry manure, fungal and pesticide residues, distiller grains sludge, etc., to eliminate pests through trough, stack, or tank fermentation. Usually, according to the needs, small processing quantities can be processed using a stack style, while for medium-sized and large-scale organic fertilizer processing, tank fermentation is used.

In trough fermentation and maturation, the use of turning piles and throwing is used to achieve oxygen supplementation, ventilation, water control, temperature control, etc. for the raw materials. By using fermentation and maturation techniques, sterilization and pest control can be achieved, and organic matter, NPK, and other nutrient rich elements can be increased.

Organic fertilizer granulation process

Organic fertilizer granulation needs to be mixed first. In the process of producing a series of specialized fertilizers, nitrogen, phosphorus, potassium, and fermented materials are mixed by computer according to different soil conditions and crops according to the formula, and then transported to the granulator for granulation. The formula of organic and inorganic raw materials is mixed according to different series of products. Mix thoroughly in the mixer.

Due to the production of biofertilizers, which mainly rely on organic matter, have a high amount of cellulose, poor forming conditions, and the addition of live bacterial communities with fertilizer making functions, the production process is characterized by avoiding exposure to high temperatures. The material manufacturing method adopts disc granulation, extrusion, and new granulation methods, because these three processes require high crushing fineness of the raw materials, high granulation moisture content, and generally a moisture content of about 30%. After opening, the particle moisture content is low, and the drying load is small, which can reduce the loss of effective bacteria, reduce dust, and have a good operating environment.

The raw materials enter the granulator, add an appropriate amount of water or steam, and bond into granules. After granulation, the materials are sent to the dryer through a belt conveyor for drying. The particle diameter is 3.0-4.0mm, and the granulation rate is greater than 70%.

The organic fertilizer production line requires equipment such as fermentation turntables, organic fertilizer crushers, drum screening machines, horizontal mixers, disc granulators, rotary dryers, coolers, screening machines, coating machines, packaging machines, conveyors, etc. The equipment configuration, model, and price required by the customer are different. The specific price is negotiable.

In the process of organic fertilizer processing production line, fermentation and granulation are two important processes in the production line. The organic fertilizer production line of Taian Hongxin Environmental Protection Technology follows a one-to-one process, with each line customized according to customer needs. The equipment is superior.
