bagasse pellet machine

Currently, bagasse pellet mills are commonly used to process bagasse fuel. Because bagasse combustion produces low sulfur dioxide emissions, only using a water film dust collector can make the flue gas emissions meet the standard, thereby reducing emission costs.

At the same time, the electricity or steam generated can be used by sugar factories and exported. There have been many studies on bagasse boilers to make their combustion efficiency more and more efficient.

In terms of feed processing, more and more customers are focusing on this field. Because as an alternative raw material, the low cost and high efficiency of bagasse are very worth looking forward to.

Sugarcane bagasse is a by-product of sugarcane sugar processing. Although it contains a large amount of cellulose, lignin and hemicellulose, direct feeding will affect the feed intake and digestibility of ruminants, but these problems can be solved through biotechnology.

1. Raw material advantages

In recent years, with the improvement of sugar production technology, the production of bagasse in many countries has been further improved.

In addition, the demand for it in the paper and board industries is small, so bagasse can ensure sufficient supply as a raw material for biomass pellets.

For traditional biomass pellet raw materials, such as wood chips, there are problems such as scattered raw material supply, difficulty in collection, wide variety, and unstable properties.

The actual production process needs to be adjusted according to the properties of the raw materials.

In comparison, bagasse is directly supplied by sugar mills, with sufficient raw material supply and relatively stable properties. Subsequent processing and production do not require frequent adjustment of operating parameters, and the production efficiency is high.

2. Process advantages

In terms of bagasse pellet machine and bagasse pellet plant technology, sugarcane pellets have very obvious advantages over the most common wood pellets. Wooden raw materials are strong and need to be torn before crushing.

This process consumes huge energy and labor costs. Bagasse has small particles and low strength and can be crushed without tearing, which can greatly save processing costs.

In addition, bagasse is more fluffy than wood, and can fully contact with flue gas during the drying process to dry thoroughly, and the drying cost is relatively low.

3. Application advantages

Sugar production companies produce a large amount of bagasse as a by-product every year.

• Due to the high moisture content of bagasse, its transportation cost is high and the transportation distance is limited.
• Due to policy and environmental constraints, there are not enough paper mills and power plants to digest bagasse, resulting in a large surplus of bagasse.

While many other industries have high demand for energy, high-value processing of bagasse to prepare bagasse biomass pellets can be easily transported overseas or used in local specialty industries.

It is expected to solve the problem of excess bagasse, alleviate environmental pressure, and increase the sugar industry’s demand and economic benefits.

Regarding the quality standards of pellet products, there are relevant regulations in the industry standard NY/T 1878-2010 “Technical Conditions for Biomass Solid Molded Fuel”.

Item	Pellets fuel (herbs type)	Pellets fuel (wood type)
Diameter/Maximum cross-section size (D) (mm)	≤25	≤25
Length(mm)	≤4D	≤4D
Molded fuel density (kg/m³)	≥1000	≥1000
Moisture content (%)	≤13	≤13
Position calorific value (MJ/Kg)	≤10	≤6
Broken rate (%)	≥13.4	≥16.9

For biomass pellet fuel, there are clear limits on its diameter and length. If it is too long and too thick, it may cause problems such as uneven feed to the biomass burning boiler.

In order to ensure that the fuel has sufficient thermal efficiency, there are clear regulations on pellet density, crushing rate and calorific value.

This requires the raw materials to be crushed as thoroughly as possible and the particles to be pressed as tightly as possible to ensure that the product has good heating properties.

Moisture content is one of the most important indicators affecting the calorific value of biomass. The lower the moisture content of the fuel, the higher the combustion efficiency, but it means that the drying cost will increase.

The specific drying indicators still need to be evaluated and determined. In the industry standards The moisture content of pellet fuel is required to be ≤13%.

In addition, ash content is also an important indicator of the quality of biomass pellet fuel. Its content directly affects the coking problem of biomass boilers. Specifying ash content is of great significance to inhibit boiler coking and reduce equipment maintenance costs.

Bagasse in Brazil is used to provide energy for cogeneration plants or national grid, but there are still around 25 million tons which are not used.

If those 25 million tons of sugar cane waste can be transformed into pellet fuel, it will make great benefit and profit to meet the growing demand of pellet fuel on the market.

1. For making bagasse into fuel, a pellet mill is required.
2. Firstly, the bagasse is processed into powder.
3. There are a die and a set of rollers inside the pellet mill. The rotary roller will press the bagasse powder out of the hole of the die into small granules.
4. Outside of the mill, there will be cutters to shorten the granule with the length between 3 and 5 cm.
5. Besides pelletizing, there are still other processes including crushing and drying the raw material, and cooling and packaging the pellets.
6. That is to say, besides pellet mill, other auxiliary accessories are needed together with crusher, dryer, cooler and packaging machine to make up a total pellet making production line.

In addition to the above equipment, RICHI Machinery will provide you with a series of services such as solution design, manufacturing, civil engineering, installation, commissioning, and after-sales services.

To process 10 tons of bagasse pellets, you need not only a granulator, but also a lot of equipment. You also need us to configure a suitable process and equipment layout for you.

Generally speaking, the production of 10t/h sugarcane sugarcane bagasse pellets is divided into several steps:

1. Crushing: Use a high-efficiency bagasse pulverizer to crush the raw materials into powder with a particle size of 3-5mm.
2. Drying: The moisture of fresh bagasse is about 48~50%. Ensure that the moisture of bagasse is dried to 10-15% to solidify the bagasse. Use a sugarcane bagasse dryer for drying. As one of the professional bagasse dryer manufacturers, we can provide a variety of customized dryer products.
3. Granulation: The bagasse powder materials are fed into the bagasse pellet machine, and they will be compressed into pellets through the movement of the mold and a set of rollers inside the mill.
4. Cooling: Use pellet cooling machine. This unit can save floor space and processing time. Cooling the pellets makes them easier to package and ship.
5. Packaging: After the bagasse pellets are cooled, they are screened and qualified pellets are packaged in a packaging machine for easy storage and transportation.

As a biomass raw material, sugarcane bagasse is uniformly transported to the bagasse yard by the belt of the pressing workshop.

The source is concentrated and the collection method is simple, saving a lot of raw material collection costs; the bagasse composition is stable and suitable for industrialization and large-scale production.

Sugarcane bagasse is used as raw material, and through processes such as crushing, drying, additive mixing, and extrusion, it is made into granular, new clean fuel that can be burned directly.

Its products can be used as the best substitutes for traditional energy sources such as coal, diesel, and natural gas.

Because after using the bagasse pellet machine to process the bagasse into pellets, the bagasse pellets will have the following advantages:

1. High return on investment.
   The cost of raw materials is low, the investment in equipment is small, and the operation is simple. Ordinary people can operate the equipment with simple training, labor costs are very low, and coal prices fluctuate greatly. These factors ensure a better return on investment.
2. Wide range of applications.
   Bagasse pellets are easy to use and store. It can be used for heating, domestic stoves, hot water boilers, industrial boilers, biomass power plants, etc. to replace firewood, coal, fuel oil, and liquefied petroleum gas. It is also suitable for family units; the combustion effect is good and can meet the needs of cooking, heating, and bathing, especially the necessities of biomass power plants.
3. Environmental benefits.
   Bagasse pellets made by bagasse pellet machine are good for the environment. Bagasse pellets are carbon neutral, meaning that the carbon dioxide emissions they produce are absorbed by themselves during the growth process. They do not release other air-polluting gases into the air.
4. Renewable.
   Bagasse pellets unlike fossil fuels such as coal and natural gas which are consumable (formed over a long period of time), bagasse pellets are renewable because sugar cane grows every year, so we can provide an unlimited amount of raw material.
5. Turn waste into treasure.
   As energy demand increases and fossil fuels decline, no one can guarantee price stability. However, the cost of bagasse pellets can be controlled. In the context of global energy shortage, bagasse pellets represent the transformation of “waste” into wealth. Sugarcane is fully utilized, and in addition, it also increases farmers’ income.

The calorific value is the primary indicator used by most manufacturers to evaluate biomass raw materials.

Usually, the calorific value of wood pellets is generally above 4000 kcal/kg, while the calorific value of straw pellets is between 3000 and 4000 kcal/kg.

The calorific value of bagasse pellets is similar to that of straw pellets, slightly lower than that of wood pellets, and the amount of pellet raw materials required to provide unit heat is larger.

At the same price, many people prefer to use wood pellets, which is understandable. But for those who can obtain bagasse resources at very low cost, choosing bagasse pellets is obviously more beneficial.

In addition, increasing the caloric value of pellets is an important way to enhance the competitiveness of bagasse pellet products.

In production, the caloric value of pellet products can be increased by compounding bagasse with wood chips with high calorific value.

In addition, increasing the drying intensity according to the actual situation will reduce the moisture content of the product and also enhance the combustion efficiency of the pellets.

The development of sugarcane by-products as non-grain feed resources can not only alleviate the conflict between humans and animals competing for food, but also save feed costs and avoid the environmental pressure caused by the littering of sugarcane by-products, which is in line with the ecological civilization construction goals of many countries.

The crude protein content of sugarcane by-products is not low compared with other common crop straws. Although its fiber content is high, it can be improved through physical, chemical, biological methods and composite treatments.

In the future, further in-depth research can be conducted on the collection of by-products, improvement of processing equipment and optimization of compound processing, and can be extended to the feed utilization of other agricultural and by-products to effectively solve the problem of lack of conventional roughage.

All in all, sugarcane by-products are characterized by rich nutritional value and huge yields, and are worthy of vigorous promotion in ruminant production applications.
