1. Why produce biomass organic fertilizer?

Biofertilizers are means of fixing the nutrient availability in the soil. Generally Nitrogen deficiencies.

Since a bio-fertilizer is technically living, it can symbiotically associate with plant roots. Involved microorganisms could readily and safely convert complex organic material into simple compounds, so that they are easily taken up by the plants. Microorganism function is in long duration, causing improvement of the soil fertility. It maintains the natural habitat of the soil. It increases crop yield by 20-30%, replaces chemical nitrogen and phosphorus by 30%, and stimulates plant growth. It can also provide protection against drought and some soil-borne diseases.

It has also been shown that to produce a larger quantity of crops, biofertilizers with the ability of nitrogen fixation and phosphorus solubilizing would lead to the greatest possible effect.

They advance shoot and root growth of many crops versus control groups. This can be important when implementing new seed growth.

Biofertilizers also promote healthy soil, leading to greater farming sustainability.

2. Raw materials for the 10 tons/hour large-scale organic fertilizer pellet production line project

The raw and auxiliary materials and energy involved in the production of this project are shown in Table 1. The material balance is shown in Table 2.

Table 1 List of raw and auxiliary materials and energy consumption

Table 2 Material balance sheet

Physical and chemical properties of main raw and auxiliary materials:

(1) Humic acid

Humic acid is a complex organic matter formed by animals and plants through long-term physical, chemical, and biological actions. The bottom mud and soil of water bodies contain humus. Humus is a macromolecular polymer with a complex chemical structure, all with carboxyl groups, phenol groups, and ketone groups. Iso-active groups with molecular weight ranging from 102 to 106 and particle size ranging from 0.5-10 mm. The composition of humus is different from different sources. Humus can be divided into humic acid, also known as humic acid, fulvic acid, and humin according to their solubility differences in acid and alkali. Application: In agriculture, humic acid fertilizer combined with nitrogen, phosphorus, potassium and other elements (for example: humic acid can be neutralized with ammonia to make ammonium humic acid fertilizer), which can increase fertilizer efficiency and improve soil , Stimulate crop growth, improve the quality of agricultural products and other functions; nitro humic acid can be used as an acid regulator for rice seedling raising.

(2) Cottonseed residue

Cottonseed residue is the waste produced by the processing of cottonseed hulls. As a kind of biomass waste, it contains a large amount of cellulose, hemicellulose, and lignin, which has good reuse value.

(3) Plant ash

Plant ash is the residue after burning plants (herbs and woody plants). The main component is potassium carbonate. The relative molecular weight is 138. Plant ash fertilizer is the ash after burning of plants, so all the mineral elements contained in plants are almost in the plant ash. It contains potassium, the most content of which is potassium, which generally contains 6-12% potassium, of which more than 90% is water-soluble and exists in the form of carbonate, followed by phosphorus, which generally contains 1.5-3%; it also contains calcium and magnesium , Sulfur and iron. Plant ash is a kind of inorganic farm manure with wide sources, low cost, complete nutrients and obvious fertilizer efficiency.

(4) Bacillus subtilis

Bacillus subtilis is a kind of bacillus or cocci that can form spores (endospores). The bacteria function has strong moisture retention, strong decomposition of organic matter, rich metabolic products, strong antibacterial and harmful effects, and can be decomposed to produce foul smell Gas organic substances, organic sulfur compounds, organic nitrogen, etc., improve the environment and other functions.

5. Production process steps of 10 tons/hour large-scale organic fertilizer pellet production line project

This project is the production of bio-organic fertilizer and microbial inoculants, sharing a production line. The production process is basically the same, except that the ratio of various raw materials is different according to market product requirements, and the amount of bacteria added is different. The project uses humic acid, furfural residue, and Bacillus subtilis as raw materials, and is the product after granulating, drying, cooling, and screening.

The specific production process is as follows:

(1) Material preparation

First, the purchased humic acid, cottonseed residue, plant ash, Bacillus subtilis, etc. are transported to the raw material warehouse for temporary storage, and then transported to the silo feeding port with a forklift. The raw materials used in the project meet the technological requirements.

(2) Feeding

Workers use a forklift or a shovel to put cottonseed residue, plant ash, and humic acid into the loading port of the silo. The bottom of the silo is connected with a conveyor belt, and the middle is connected with a chute, and is sealed.

(3) Measuring and conveying

The material in the silo enters the integrated conveyor belt through the automatic belt. There are three integrated conveyor belts in this process. The purpose of mixing materials is achieved through the process of layer-by-layer blanking. The mixing is only a simple physical mixing.

(4) One-time granulation

The granulation process is the core part of organic fertilizer production. The materials in the silo (including the returned materials in the screening process and the particles collected by the bag filter) are conveyed to the disc granulator by the belt, and the disc rotates counterclockwise under the drive of the reducer. , Water is added to the raw materials through the nozzle set above the granulator (or the water washing tower drains), so that the materials are automatically formed into balls to reach the required particle size, and finally discharged from the discharge port and conveyed to the next process by the belt conveyor.

(5) One stage drying

The main purpose of this process is to dry the moisture in the material to meet the requirement of product quality moisture ≤ 30%. After the first granulation is completed, the material is sent to the dryer through the conveyor belt, and the drying is to introduce the hot air through the fan to directly heat the material. The drying temperature is 90℃. The material is dried under the action of the inclined plate. The star discharge valve of the other section of the dryer is discharged to the belt conveyor, and then conveyed by the belt to the cooling process.

(6) One stage cooling

The dried material is conveyed to the rotary cooler through the belt, and the axial fan is used for forced air cooling to further remove the moisture of the material and lower the temperature of the material to less than 50°C. The cooled material enters the screening process.

(7) Screening

The cooled material is lifted by the belt to the drum screen for screening. The project selects a screener with a suitable particle size to screen the material. The production line is equipped with an automatic return system, and the particles with a large particle size (diameter greater than 4.5mm) are left on the upper layer of the screen. The large particles sieved out fall to the return belt and are transported to the crusher for crushing, and the material under the sieve is transported by the belt to the secondary granulation process.

(8) Broken

The unqualified large particles screened out in the screening process fall to the return belt and are transported to the crusher for crushing. The crushed materials and small particles are fed into the silo through the conveyor belt.

(9) Secondary granulation

The secondary granulation process is the same as the primary granulation. The material after the second granulation enters the second stage of drying.

(10) Two-stage drying

The secondary drying process is the same as the primary drying. After the second stage of drying, the material enters the second stage of cooling.

(11) Two-stage cooling

The second-stage cooling process is the same as the first-stage drying, and the cooled material enters the screening process.

(12) Screening and crushing

After the second stage of cooling, the material is lifted by the belt to the drum screening machine for screening. The project selects a screen with a suitable particle size to screen the product. The production line is equipped with an automatic return system. The finished product and small particles enter the fine screen through the screen, with a large particle size The particles flow out from the upper layer of the sieve. The large particles (d>4.5mm) sieved out by the coarse sieve are crushed and the small particles (d<2mm) sieved out by the fine sieve are recycled and reused in the feeding process. The qualified materials (2mm< d<4.5mm) is transported to the bacteria addition process through a belt conveyor.

(13) Adding bacteria and packaging process

The material that meets the particle size requirements is screened and sent into the coating machine through a belt conveyor, and the bacteria agent and the material contact and bond in the coating machine to achieve the purpose of adding the bacteria agent. After the completion of the bacteria addition, the materials are automatically measured with an electronic scale, and packaged with a packaging machine, and then moved to the finished product warehouse for storage and sale.

The total investment of the project is 16.92334 million RMB, of which environmental protection investment is 1 million RMB, accounting for 5.91% of the total investment; the project covers an area of ​​20,000m2, with a building area of ​​16,068m2, and mainly constructs production workshops, raw materials workshops, packaging workshops, etc.; the project has 67 labor quotas , The employees are all transferred by Hebei Xingbai Pharmaceutical Group (Hebei Xingbai Biotechnology Co., Ltd. starch sugar workshop stopped production and transferred some of its employees to this project), and the group did not add new employees. The project works 300 days a year, using a three-shift system with 8 hours per shift.
