1T/H Straw Pellet Production Line in Vietnam

Origin of 1 t/h straw pellet production line in Vietnam

The development of biomass resources and straw resources is a strategic measure to promote energy conservation and emission reduction. It 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 make rational and effective use of agricultural resources.

Choosing biomass pellet fuel instead of burning coal and oil can not only meet the requirements of environmental protection, but also be more affordable. In this context, in order to meet market demand and increase corporate benefits, the client of this project decided to invest US$180,000 to build this straw pellet plant project with an annual output of 2,500 tons.

The 1 t/h straw pellet production line in Vietnam project covers a total area of 480m2 and is mainly made of agricultural straw and bark. , waste wood chips, sawdust, pasture, cereal grass, etc. are used as raw materials and processed into biofuel straw pellets.

Production process of 1 t/h straw pellet production line in Vietnam

01 Raw material processing: Straw has many components, including various celluloses, hemicelluloses and lignin. When processing straw, it is necessary to remove foreign matter and remove impurities, and at the same time separate the straw to ensure the quality of the straw.

02 Drying: Straw has a high moisture content and needs to be dried. After drying to remove moisture, production costs can be reduced and the density and quality of the particles can be improved.

03 Crushing: The dried straw needs to be crushed and processed into small particles to facilitate subsequent granulation processing. Common crushing methods include blade and hammer mills.

04 Granulation: The core step of straw granulation is granulation. The crushed straw is processed through a straw pellet machine, heated to a certain temperature and then pressed into cylindrical or spherical pellets. The granulation process is divided into two stages: shaping and hardening.

05 Cooling: After granulation, the surface temperature of the straw pellets is high and cooling treatment is required to prevent spontaneous combustion of the straw pellets and is also beneficial to the storage and packaging of the straw pellets.

06 Screening: After the straw pellets are cooled, they need to be screened to screen out the straw pellets that are too large or too small to ensure the uniformity of the straw pellets.

07 Packaging: The straw pellets processed through the above steps need to be packaged. Common packaging materials include bags and bulk.

In general, the production process of straw pellets is a comprehensive technology that includes multiple steps. The processing method of each step needs to be strictly controlled in order to produce high-quality straw pellets.

Noise	The main noise sources of the project are mechanical noise and aerodynamic noise such as crushers, granulators, fans, etc. The source intensity is 75-83dB(A). By taking measures such as vibration reduction, sound insulation, and installing mufflers on fans, the noise at the factory boundary has been reduced. It can meet the "Environmental Noise Emission Standards at the Boundary of Industrial Enterprises".

First of all, we all know that straw is the waste left after harvesting crops. If not utilized, they can become a source of environmental pollution. Nowadays, with the increasing depletion of resources and the increasingly serious environmental problems, the development and utilization of new energy has become a top priority.

In this context, straw pellet fuel has become a very promising new form of energy. So, what exactly is straw pellet fuel? Simply put, it processes straw and compresses it into small particles for combustion.

This kind of fuel has the advantages of high calorific value, low ash content, low sulfur content, and low nitrogen oxides. It can not only replace traditional fuels, but also reduce the environmental burden and achieve environmental protection and energy saving.

Straw pellet fuel processing is a very meaningful job. It can not only solve the problem of waste straw disposal, but also contribute to the development and utilization of new energy.

In addition to this 1 t/h straw pellet production line in Vietnam project, Richi Machinery has currently exported straw pellet machines and straw pellet production lines to Malaysia, Indonesia, India, Moldova, Russia, Germany, the United States, Canada, Australia, New Zealand, Argentina, Brazil, South Africa, Ghana and other countries.

The processed pellets can be used for both fuel and feed. If you are also interested in starting straw pellet processing business, contact Richi Machinery to get a detailed production line design plan and quotation!
