How to make organic fertilizer from cocoa waste?

In the process of cocoa bean processing, there are a lot of wastes, such as bean shell, seed coat, seed embryo and so on. These wastes are treated and have certain use value. Cocoa waste is mainly bean shell, which contains more protein and fiber, and can be used as feed or organic fertilizer.
Bode shell is rich in nitrogen, phosphorus and potassium. Because the cocoa tree needs more potassium and the content of potassium carbonate in the bean shell is high, the bean shell is very suitable for the production of organic fertilizer raw materials.

Compost Making
Compost Making

Cocoa seed coating is also suitable for use as organic fertilizer. Fertilizer made from seed coating can reduce the viscosity of the soil and play the role of humus and humus. Seed coat is not easy to decompose. In the fermentation of organic fertilizer, seed coating needs to be pretreated, crushed into small pieces, and then composted for fermentation.
The production of organic fertilizer from cocoa waste can be divided into two stages: composting fermentation and organic fertilizer production equipment processing.

Fermentation composting of cocoa waste

The weight of bean shell accounts for a large part of the weight of cocoa fruit itself. After the cocoa beans are removed, the shells are usually discarded in situ. Pod shells are of great value. Therefore, the proximity principle should be adopted in the selection of organic fertilizer production site to facilitate the fermentation of raw materials.

Cocoa processing waste (bean shell, seed coat) is put into fermentation tank, and animal manure such as chicken manure, pig manure and cow manure are all added with regulating raw materials. After high temperature fermentation, harmful bacteria are killed.

Processing cocoa compost with organic fertilizer production equipment
Fermentation compost is produced into fertilizer products by the industrial processing of organic fertilizer production equipment. The basic fertilizer equipment for cocoa composting processing includes fertilizer crusher, mixer, organic fertilizer granulator, rotary dryer, rotary cooler and packaging machine. Different fertilizer products can be produced by different processing technologies.

BB Fertilizer Basis

Bulk mixed fertilizer, also known as BB fertilizer, is composed of two or two or two kinds of high concentration raw material fertilizers with larger particle size, which are mixed in a certain proportion according to the needs of users.

The appearance of this fertilizer seems to be uneven, but its nutrients are actually equivalent to other compound fertilizers. In the production of bulk mixed fertilizer, all raw material fertilizers must be granular, and the particle size is basically similar, so as to prevent the aggregation of the same particle in the production, storage, transportation and use of the mixed fertilizer, and produce a single fertilizer effect.

Application of bulk mixed fertilizer

The formula of bulk mixed fertilizer can be adjusted flexibly, especially suitable for areas with large land area, complex soil types and many crop types. It is widely used in developed countries in the United States, accounting for about 40% of the total consumption of chemical fertilizer.

How to appy bio fertilizer products?

The application of organic fertilizer can improve the soil structure, but its effective nutrient content is low and the fertilizer efficiency is slow. Biological fertilizer can enhance soil fertility, stress resistance and disease resistance, but the biological fertilizer itself does not contain nutrients.

According to the advantages and disadvantages of chemical fertilizer, traditional organic fertilizer and biological fertilizer. Zhengzhou SX chemical fertilizer plant has developed a new type of compound biological fertilizer, which has the functions of biological bacteria activating soil and transforming soil nutrients. We also designed the production method of biological fertilizer.

Benefits of applying biological fertilizer

2. Biological fertilizer can increase the nutrient content of nitrogen, organic matter, soluble phosphorus and soluble potassium in soil, increase the number and quantity of beneficial microorganisms in soil, and enhance the function of disease resistance, drought resistance and metabolism of crops.

3. Biological fertilizer has a positive effect on increasing crop yield, improving crop quality and increasing agricultural economic income.

Production technology of pellet bio fertilizer

Due to the advantages of powder fertilizer, such as convenient agglomeration, uneven volume, unfavorable mechanized application, inconvenient transportation and storage, and serious use of biological fertilizer, granulation of biological fertilizer is an urgent need in actual production. The pan type fertilizer granulator is more suitable for the production of biological fertilizer.

Production of biological fertilizer with Pan fertilizer granulator

The effects of production formula, grinding fineness and water content of powdered fertilizer on granulation effect of compound biological fertilizer were studied. The fermented organic fertilizer was crushed and screened, and then mixed evenly with a certain proportion of inorganic fertilizer, and granulated by a pan fertilizer granulator. The pan type fertilizer granulator is equipped with spraying device, which can evenly add water to the material. In the process of biological fertilizer production, granulation is carried out according to the appropriate parameters, so as to improve the production efficiency.

Biological fertilizer granules are dried and screened to obtain the fertilizer we need.

Slow Release Fertilizer Production Process

Slow release controlled fertilizers release nutrients slowly in the soil to meet the nutrient requirements of the whole crop growth period. In the process of NPK fertilizer production, slow release and control of fertilizer are realized by granulation and coating.

Slow release fertilizer means that the release rate of available nutrients in plants is lower than that of fast fertilizer after fertilization in soil. Controlled release fertilizer refers to the regulation of nutrient release according to the set release mode and nutrient absorption law of crops. Release not only refers to the release period of fertilizer, but also refers to the release rate of nutrients in fertilizer, which conforms to the law of crop fertilizer demand.


Ideally, controlled release fertilizer can artificially control the supply and release rate of nutrients according to the nutrient requirements of different stages of crop growth. That is to say, nutrients can be released when crops need them and retained in the soil when they are not needed, so that a single application can meet all stages of crop growth.

NPK fertilizer production line processing slow release controlled fertilizer
NPK fertilizer production line can slow release and control fertilizer through fluidization treatment. The main production processes are: batch processing, mixing, granulation, drying, cooling, screening, coating, packaging. Fertilizer granulator is the key to slow release and control fertilizer processing. It determines the size, shape and hardness of fertilizer particles. Fertilizer granulator determines the appearance of the product, and the physical shape of the product also affects the fertilizer effect.

Rotary drum granulator is usually used for slow release and controlled fertilizer production for granulation. The roller granulator has the advantages of large production capacity, low production cost and spherical particles meet the production requirements of slow release fertilizer. The final stage of NPK fertilizer production and processing is coating. After particle coating, it becomes slow release fertilizer.

Urea fertilizer coating

With the continuous improvement of agricultural science and technology, the promotion of high-yield varieties, the improvement of land re cultivation index, the vigorous development of economic crops, flowers and urban greening. The phenomenon of crop growth and soil nutrient ecological balance is becoming more and more serious, and the phenomenon of crop sulfur deficiency is becoming more and more serious.

Sulfur urea has become a popular fertilizer product in the market. It is coated with sulfur and other trace elements on the outside of urea by coater and pulverizer, so that the nutrients of fertilizer are released slowly. It is different from the technology of rotary drum granulator of compound fertilizer.

Why should sulfur coated urea fertilizer be used

1. sulfur coated urea can improve the utilization of fertilizer, similar to the granular fertilizer made by disc granulator, and can control the release rate of fertilizer nutrients. Especially, the utilization rate of nitrogen fertilizer can be greatly improved, the efficiency of fertilizer can be nearly doubled, and the agricultural investment can be greatly reduced and the environment can be protected.
2. increase crop yield greatly. The application of different soil and crop has a good effect on the yield.
3. the sulfur coated urea fertilizer can improve the quality of the crop products.
4. fertilizer can be used as soil conditioner, and the effect of the treatment of saline alkali land is good.
5. reduce labor input.

The application of sulfur coated urea fertilizer at one time can meet the needs of different growth stages of crops. With the high cost and shortage of modern agricultural labor cost, the application of sulfur coated urea in some crops also shows its characteristics.

For example, planting sugarcane, because the cane grows for months, it is not easy to mechanized fertilization after the crown is closed. In the early stage of self-growth, single fertilization can meet the needs of crops and is welcomed by sugarcane farmers. Strawberries grown in plastic mulch are also easy to apply nitrogen, so 70 percent of California’s strawberry growers use sulfur coated waste.

We provide a complete production line of sulfur coated urea, as well as the chemical fertilizer production equipment such as disc granulator, drum granulator, double roller granulator, coating machine, packaging machine and so on.

How to make granules fertilizer with pan granulation machine?

Organic-inorganic compound fertilizer is a compound fertilizer that integrates organic matter and inorganic fertilizer. Organic-inorganic compound fertilizer has various components, which can not only provide crop nutrients, but also improve soil biological activity and soil fertility, so it is widely used in cash crops.

Organic matter is an important component in organic-inorganic compound fertilizer, and its content directly determines the actual effect of bio-organic compound fertilizer. Therefore, the granulation process of organic-inorganic compound fertilizer production line is particularly important. The organic fertilizer disc granulation production line can realize the complete treatment of organic-inorganic compound fertilizer.

For the pan granulator, the addition of organic matter is also the key to granulation. Want to know how does the granulator make fertilizer granules by wet granulation method, welcome to https://www.fertilizermachinesale.com/pan-granulation-process/

Disc Pelletizer for Small Scale Cow Farm Manure Granualtion
According to the actual situation, several kinds of materials with abundant raw materials, low price and convenient processing can be selected as the raw materials of the pan granulator.

Organic fertilizer: chicken manure, pig manure, peat, plant ash, etc.
Inorganic fertilizers: urea, ammonium sulfate, superphosphate, calcium magnesium phosphate, potassium sulfate, potassium chloride, etc.

Organic compound fertilizer disc granulator

Organic fertilizer has strong water absorption and looseness, and its water content, fineness and other factors have a greater impact on granulation. Therefore, organic matter plays an important role in the production of disc granulators. On the premise of keeping the compound fertilizer and other inorganic nutrients unchanged, increasing the input of organic matter is an important way to improve the quality of biological compound fertilizer.

However, organic matter has strong dispersibility and has a greater impact on granulation. The organic content is too high, which is not conducive to the production of the pan granulator.

Experiments show that in the production line of organic fertilizer disc granulation, the amount of organic matter is about 25%-35%, and a better granulation effect can be obtained. The process of organic fertilizer disc granulation production line is suitable for the production of granular organic-inorganic compound fertilizer.

How to make npk fertilizer graules?

The physical and chemical properties, apparent structure and internal structure of products produced by different NPK compound fertilizer production processes are different. It leads to the difference of nutrient release, soil acidity and root zone nutrient change, which affects the relationship between nutrient release rate and soil nutrient supply and demand, and finally leads to crop growth. Differences in yield and fertilizer efficiency.

NPK Fertilizer Production Line Design Layout

Therefore, the difference of fertilizer efficiency between different processes of compound fertilizer is due to the differences of physical and chemical properties and structural characteristics of compound fertilizer itself, as well as the difference of manufacturing technology. In order to improve crop yield and fertilizer efficiency, NPK fertilizer production process must be improved.

NPK fertilizer production process solid aggregate method

In this method, single alkali fertilizers (such as urea, ammonium nitrate, ammonium chloride, ammonium sulfate, ammonium phosphate, potassium chloride and sulfuric acid) are used as raw materials. After grinding to a certain fineness, the raw materials are gathered and granulated in the drum of the rotary granulator by adding water and heating.

In the process of granulation, a small amount of phosphoric acid and ammonia can be added into the rotary drum granulator to improve the granulation conditions of NPK fertilizer production. It is one of the methods widely used in the world to obtain compound fertilizer products by drying, sieving and cooling granular materials. This method was used by the early United States, India, Japan, Thailand and other Southeast Asian countries.
