Peanut shells turn waste into treasure

Peanut shells are waste? No, statistics show that peanut shells make up about 20% of the weight of dried peanut pods. It may be a raw material for new energy materials, using peanut shells to make pellets for customers to replace coal as an important fuel. How to find your own peanut fuel treasure from garbage?

Peanuts and peanut shells

Peanut (peanut), formerly known as groundnut (scientific name: Arachis hypogaea Linn.), is a kind of nut with rich yield and wide edible range, also known as "longevity fruit", "mud bean", "bean" and so on. It belongs to Rosaceae, an annual herbaceous plant of legume family, with erect or prostrate stems, 30-80cm long, wing petals separated from keel petals, pod length 2-5cm, width 1-1.3cm, expansion, pod thickness, flower and fruit period 6-8 months. Mainly distributed in Brazil, China, Egypt and other places. There are various types of peanuts all over the world, characterized by branching habit and branch length. The large amount of peanut production has left a rich source of peanut waste, such as peanut hulls and peanut fiber, which is now considered a potential fuel source.

The value of peanut shells

After harvesting and dehulling, the peanut shell or shell is separated from the nut, accounting for about 20% of the weight of the dry peanut pod, which means that a large amount of shell residual biomass is left after processing. Peanut shells are used as cattle feed, poultry litter and garden mulch, and they are now seen as a potential source of fuel.

Composition of peanut shell

Although the composition of peanut shell varies from variety to variety, the main chemical composition of peanut shell does not change greatly due to variety. The main components of peanut shell are cellulose 37.0%, lignin 28.8%, protein 8.2%, carbohydrate 2.5%. The composition of peanut shell makes peanuts a disguised treasure, which can be used as fuel and feed production.

Peanut Shell Fuel Particles

In order to make full use of peanut shells and develop new energy sources, peanut shells can be pressed into fuel pellets with a peanut shell pellet machine. The peanut shell granulator has two kinds of flat die and ring die. The former is usually used for small-scale pellet production and is favored by household users and farmers, while the latter is used for large-scale pellet production, and medium and large pellet producers are used for large boilers and power generation.

Advantages of peanut shell particles

Peanut shells are directly used as fuel, with large volume, low combustion rate and difficult transportation. The granulation of peanut shells will greatly improve its storage and logistics. Peanut shell particles have the following advantages:

High-density peanut shell particles can ignite quickly, have good combustion performance, high combustion efficiency, and produce less ash.

Peanut shell is a common raw material, easy to obtain. This will reduce the production cost of peanut shell particles and provide a larger profit margin.

Peanut pellet fuel is a kind of green biomass energy with low emissions and environmental friendliness.

Due to its high combustion rate and easy storage, peanut shell particles can be widely used for civil heating and daily energy supply, and can also be used for industrial boilers to generate electricity.

The production process of peanut shell particles and the equipment used.

The biomass granulator pelletizes the prepared material into pellets. This step is the core of the entire production line, so the stability and high yield of the pellet machine are the top priorities for customers.

The pellet cooler cools the newly extruded hot pellets and hardens the pellets. The process after the particle machine is to cool the particles. The speed of natural cooling is too slow and the cooling is uneven. It is necessary to use a professional particle cooler.

Biological particles ton bag packaging equipment according to the requirements of packaging particles, can be small bags can also be tons of bags.

Conveying equipment, placed at the front and back ends of the host equipment to help transport raw materials during the production process

Electric control cabinet, control the entire production line of all equipment power

As the core of pellet production, the pellet machine determines the quality of bamboo in the entire production line. YULONG vertical ring mold biomass fuel pellet machine is very suitable, because of its strong adaptability, simple operation, convenient maintenance and other characteristics, has been strongly recommend.

For large-scale pellet production, it is recommended to use a vertical ring die pellet machine because of its high production capacity.

Precautions for Particle Processing

1. Before operating the machine, the operator should carefully read the instruction manual and be familiar with the various technological processes of the equipment.

2, the production process, to strictly in accordance with the procedures and sequence of operation, and according to its requirements for installation and operation.

3. The host equipment needs to be installed and fixed on the horizontal concrete floor to reinforce the tightening screws.

4. Smoking and open fire are strictly prohibited in the production site.

5. After each startup, you need to idle for a few minutes before feeding.

6. It is strictly prohibited to add hard debris such as stone and metal to the feeding device. Iron removal shall be done before granulation to avoid damage to the granulation room.

7. During the operation of the equipment, it is strictly forbidden to use hands or other tools to transfer materials to avoid danger.

8. If there is any abnormal noise in the production process, the power supply should be cut off immediately, and the abnormal situation can be checked and handled before starting the machine to continue production.

9. Before stopping the machine, stop the auxiliary feeding first, then put in the oil, and stop the machine only after the die hole is full of oil and there is no oil in the granulation chamber. The purpose of adding oil is to make it easier to discharge the next production.

Operate the granulator correctly according to the requirements and pay attention to related matters according to the requirements, which can not only improve the output and operating performance of the equipment, but also extend the service life of the equipment.
