Small Straw Pellet Plant In Tanzania

RICHI MACHINERY

overview

This is a small straw pellet plant in Tanzania project with an output of 1-1.5 tons per hour.

After market research, the client, a Tanzanian agricultural company, decided to build a new biomass straw fuel pellet plant project. The project has been completed and put into production in April 2024 with a construction scale of 2500t/a.

Biomass energy is the energy form of solar energy stored in organisms in the form of chemical energy, that is, energy with biomass as the carrier. It comes directly or indirectly from the photosynthesis of plants and can be converted into normal solid, liquid and gaseous fuels. It is a renewable resource and also the only renewable carbon source.

The development of straw biomass energy is an important aspect of promoting the development of circular agriculture and building modern agriculture; it is also an effective way to protect the ecological environment and reasonably and effectively utilize agricultural resources.

The small straw pellet plant in Tanzania project has a fixed staff of 6 people, an annual production day of 180 days, and the enterprise work system is a 10-hour production in one shift, and no production at night.

Design of the process of processing straw pellets in Tanzania

The main engineering content of the construction period of this small straw pellet plant in Tanzania project is the construction of production workshops and equipment installation.

The new production workshop of the project is a steel structure building. The construction and equipment installation plan of the production workshop will take the steel pipes driven into the ground as the fixed foundation, and set up anti-seepage dry toilets for construction personnel to use. They will be cleaned regularly for agricultural fertilizer without discharge.

Description of the process flow of this small straw pellet plant in Tanzania project:

1. Transport and unpacking

After the collected raw materials are transported into the factory, they are unpacked and stored in the material yard. After the natural drying moisture content is below 10%, they are transported to the production workshop for crushing.

2. Crushing

The raw materials are crushed in the production workshop. The crusher is equipped with a bag dust collector. The production workshop is a closed workshop with enhanced ventilation. Most of the dust settles indoors. The crushed raw materials are less than 5mm.

3. Granulation

After crushing, they are transferred to the straw pellet machine. The straw biomass pelletizer is equipped with a bag dust collector. The principle of pelletization is the collision and extrusion between the material and the machine and between the materials. Through the action of mechanical pressure, the crushed materials are squeezed into regular, denser molded materials.

4. Cooling

The temperature of the biomass pellets at the pelletizer outlet is 80-90℃, and the biomass pellets are sent to the cooler for cooling through the conveyor.

5. Packaging and warehousing

After cooling, the biomass pellets are manually packaged and bulk stored. The products are transported to the warehouse for storage. The products are sold as soon as they are produced, and no large-scale storage is done.

Tanzania project layout

1. Principles of layout

According to the location and surrounding conditions of the small straw pellet plant in Tanzania project, in accordance with the requirements of engineering construction specifications and production process flow, the RICHI engineering team combined the customer’s on-site terrain to ensure smooth process flow and convenient connection.

Strictly abide by relevant standards and specifications to ensure safe production, consider fire prevention, health safety distance and maintenance requirements, adapt to local conditions, carry out reasonable functional zoning, strive to arrange compactly, reasonably, save land, and unify planning, which is conducive to production management and environmental protection.

2. Plant layout

The gate of the plant area of ​​this small straw pellet plant in Tanzania project is located on the north side of the plant area. The production workshop of this project is located on the south side of the plant area.

The overall layout of the plant area is compact and reasonable, conforming to the shipping process, facilitating the transportation of products, daily management and emergency rescue.

The small biomass pellet production line project is arranged based on the principle of product processing and production process, which follows the direction of materials, convenient transportation, and convenient transportation of materials;

Since the small straw pellet plant in Tanzania project does not have high requirements for the external environment, the impact on the environment is relatively small. Therefore, the project is coordinated with the surrounding environment of the factory area;

The layout of the factory area can meet the production and management requirements of the enterprise, and meet the local requirements on environmental protection, fire prevention, safety, sanitation, etc.;

The passages in the factory area are wide, which can meet the transportation and fire protection requirements of the products.

Based on the above analysis, the layout of the project area is relatively reasonable.
