1. The working principle of wet wood log biomass pellet processing equipment

The core principle of wood pellet processing equipment (such as wood chip pellet machines) is to convert biomass feedstock into high-density pellet fuel through mechanical extrusion. The basic process includes three steps: feedstock pretreatment (crushing, drying, and screening), mechanical pressing, and finished product processing (cooling and packaging). For example, in a ring die pellet machine, a motor connected to a reducer via a coupling drives the ring die to rotate. Gravity forces the feedstock into the pressing zone, where the pressing rollers squeeze the material into the ring die holes. After being formed in the die, the pellets are cut into pellets of a fixed length by a cutter

2. Characteristics of wet wood log biomass pellet processing equipment

(1) High degree of automation, reducing manual intervention

The PLC control system is used to link the crushing, tempering, molding, cooling and other links, and automatically adjust the feed amount, pressure wheel speed and other parameters according to the moisture and hardness of the raw materials, reducing production interruptions caused by fluctuations in the characteristics of wet materials.

Equipped with an automatic mold cleaning device, when the mold is detected to be blocked, it can automatically reverse the pressure wheel or spray a release agent to reduce the frequency of shutdowns for cleaning.

(2) Balance between energy consumption and adaptability, taking into account both efficiency and cost

Compared with equipment that processes dry materials, wet material processing equipment consumes slightly more energy (because it needs to overcome the viscosity and moisture resistance of the wet material), but it eliminates the need for a separate drying step (or significantly reduces drying energy consumption), and the overall energy consumption may be lower (especially when the moisture content of the raw materials is extremely high).

It has strong adaptability to raw materials and can not only process wet wood, but also mix and process other high-moisture biomass (such as straw, sugarcane bagasse, etc.), making it suitable for small and medium-sized processing plants with complex raw materials.

3. Application scenarios of wet wood log biomass pellet processing equipment

It can be used for home heating and cooking (through devices like pellet fireplaces and pellet stoves). It's simple and clean to operate, replacing traditional coal and firewood to improve the indoor environment.

(1)Industrial Use:It can be used as a boiler fuel to provide steam or hot water for factories, hotels, hospitals, and more. In agriculture, it can be used for greenhouse heating and drying agricultural products (such as grains and medicinal herbs).

(2) Power Generation: It can be used as a fuel in biomass power plants, either mixed with coal or burned alone to generate electricity, contributing to the transformation of the energy structure.

TONY Brand 80-100Ton/Hour Wet Wood Log Pellet Manufacturing Plant can take wet wood, various types of wood - related biomass materials, such as branches, small - diameter logs, and wood shavings, with wet wood as the main raw material. After pretreatment and processing, it is solidified into high - density wood pellet fuel.

Project Market Analysis 

1. Market Demand 

(1) Industrial sector: With the increasingly stringent environmental protection policies, many industrial enterprises (such as food factories, chemical plants, textile factories, etc.) are restricted in the use of traditional high-pollution fuels (such as coal), and are in urgent need of finding clean and efficient alternative energy sources. Wood pellets, as an ideal biomass fuel, have similar combustion characteristics to coal, but significantly reduce pollutant emissions, can meet the heating needs of industrial boilers, and have relatively low operating costs. Therefore, the market demand in the industrial sector continues to grow. 

(2) Civilian sector: In terms of winter heating and rural living energy consumption, wood pellets are gradually gaining favor among consumers due to their environmental protection and economic characteristics. Compared with traditional coal heating, using wood pellets for heating can not only reduce indoor air pollution and improve the living environment, but also effectively reduce heating costs. In addition, with the continuous improvement of people's environmental awareness, the pursuit of a green and healthy lifestyle has also led to a continuous increase in the demand for wood pellets in the civil market. 

(3) Biomass power generation sector: As an important renewable energy power generation method, biomass power generation has developed rapidly with the support of national policies. As a high-quality fuel for biomass power generation, wood pellets offer stable calorific value and high combustion efficiency. This improves power generation efficiency, reduces costs, and provides a reliable fuel source for biomass power generation companies. Consequently, demand for wood pellets in the biomass power generation sector has been increasing year by year.

2. Market Supply

Currently, the wood pellet market primarily comes from small and medium-sized processing companies and individual operators. While there are a large number of manufacturers in the market, their overall scale is relatively small, their production equipment and technical levels vary, and product quality varies significantly. Limited production scales hinder some companies from meeting large-scale market demand. Meanwhile, some companies employ outdated production processes, resulting in pellets with low calorific value and high ash content, failing to meet the demands of the high-end market. Therefore, while overall production capacity can meet certain market demands, the supply of high-quality, stable products is relatively insufficient, creating market opportunities for new entrants.

Wood pellets are solid fuels made from wood processing waste (such as wood chips, sawdust, and shavings) through crushing, drying, and extrusion. Their main characteristics and advantages are as follows:

Core Characteristics

1.Stable Physical Form

They are regular cylindrical pellets (typically 6-10 mm in diameter and 20-50 mm in length) with a high density (approximately 1.1-1.3 tons/cubic meter). They are significantly more compact than raw wood chips (which have a density of only 0.1-0.2 tons/cubic meter), making them easier to store, transport, and meter. They are also less prone to moisture absorption and agglomeration.

2.Single Composition and Stable Combustion

Mainly composed of wood cellulose, they contain no impurities such as gangue and sulfur. They produce a stable flame, high thermal efficiency, and low ash content (typically less than 1%) during combustion, minimizing wear and tear on combustion equipment. 

3.Easy to ignite and good flame control.

Compared to fuels like coal and biomass briquettes, wood pellets have a lower ignition point (approximately 200-250°C) and ignite quickly. The combustion intensity can be precisely controlled by adjusting the feed rate, making them suitable for automated combustion equipment (such as pellet stoves and boilers).

4.Excellent environmental performance.

A renewable energy source, the carbon dioxide released during combustion is essentially balanced by the carbon dioxide absorbed during the tree's growth, achieving "carbon neutrality." Furthermore, sulfur and nitrogen emissions are extremely low (far lower than coal), meeting environmental emission standards.
