Wood briquette press is a kind of equipment used to produce wood fuel, which can press sawdust, straw, rice husk and other raw materials into various specifications of fuel through a series of processing technologies, and is widely used in the field of biomass energy. However, excessive humidity of raw materials will adversely affect the production efficiency of wood briquette press machine and the quality of briquetting fuel.

First of all, the high humidity of raw materials will affect the production efficiency of wood briquette press. In the production process, the high humidity of raw materials will increase the energy consumption of wood briquetting machine and reduce the production efficiency. Because too much water in raw materials will lead to a longer time for briquette fuel to achieve the ideal molding effect in the production process, thus increasing the production cycle and energy consumption. This will not only increase the production cost, but also reduce the production capacity of equipment and affect the economic benefits of enterprises.

Secondly, the excessive humidity of raw materials will affect the quality of briquette fuel produced by wood briquette press. Too much water in raw materials will lead to the decrease of the density of briquette fuel, poor molding effect, and easy to cause quality problems such as cracking and fracture. This will not only affect the combustion efficiency and energy release of briquette fuel, but also increase the subsequent processing and packaging costs. Moreover, raw materials with excessive humidity are prone to mildew and deterioration during storage and transportation, which affects the market competitiveness and brand image of products.

In addition, excessive humidity of raw materials will increase the maintenance cost and failure rate of wood briquette press. The briquetting machine running in high humidity environment is easy to be corroded and damaged, which leads to the increase of equipment failure rate and maintenance cost. Long-term production of briquette fuel with high humidity raw materials will also accelerate the aging of equipment, shorten the service life of equipment and increase the investment cost of enterprises.

Therefore, in order to ensure the normal operation of wood briquette press and the stable quality of briquetting fuel, enterprises should strictly control the humidity of raw materials in the production process. Raw materials can be pretreated by drying equipment to control the moisture content of raw materials within a reasonable range. Only by reasonably controlling the humidity of raw materials can we ensure the efficient and stable operation of wood briquetting machine, improve production efficiency and product quality, and thus enhance the competitiveness and profitability of enterprises.
