Piston design, energy saving 50%, stable operation 24 hours, coffee grounds briquette machine that can operate stable.

Coffee ground briquetting machine also called coffee ground log press, it is a machine used to press dried coffee grounds or coffee husks into fuel briquettes of different diameters (20mm-80mm). The packaged coffee grounds briquettes can be used as a primary fuel for home heating. Industrial-grade coffee grounds or coffee husk briquettes are generally between 20-60 cm in diameter, while those for home heating are typically 70-80 mm in diameter and 30 cm in length, allowing for prolonged burning in fireplaces.

HOW TO MAKE COFFEE BRIQUETTES?

Coffee grounds are a raw material with extremely high moisture content, typically reaching 70%-80%. Therefore, the first step in a coffee grounds briquetting production line is dehydration. Even after dehydration, the moisture content of the coffee grounds remains between 50-60%, making it unsuitable for direct use in briquetting machines. For this high-moisture raw material, a high-efficiency, multi-stage dryer is the optimal choice, offering advantages such as high output and efficiency, and enabling continuous and stable operation. After drying, coffee grounds with approximately 15% moisture content can be used directly in briquetting machines. Of course, for better adhesion, adhesives can be used or a certain proportion of sawdust can be mixed in.

step 1: Use a coffee grounds dehydrator to remove excess water.

The first step is to remove excess water using a coffee grounds dehydrator.

A screw type coffee grounds dehydrator is essential for dehydrating coffee grounds because coffee grounds have a moisture content of over 80%. Directly drying them in a dehydrator would result in very low thermal efficiency, significantly increasing operating costs. Dehydration can improve the dehydrator’s efficiency by over 50% and reduce costs. Therefore, the coffee grounds dehydrator is the first step in the entire process.

Step 2: Use a drum screen to remove filter paper and other impurities from the coffee grounds.

Coffee grounds collected from different coffee shops contain filter paper. While these materials can be used to make briquettes, to prevent the filter paper from catching fire during the drying process in next step due to its flammability, it’s best to remove it using a drum sieve. A vibrating screen can achieve the same performance, but a drum sieve is more efficient due to its rotating operation design. If the coffee grounds you collected do not contain filter cartridges or other impurities, then you can skip this step directly.

Step 3: Use a rotary drum dryer to reduce the moisture content of the coffee from 55-60% to about 15%.

High-efficiency stacked drum dryer is a biomass dryer specifically designed for high-moisture raw materials, particularly suitable for high-moisture materials like coffee grounds. However, it’s important to note that you need to determine the heat source to use as fuel for the rotary dryer. We do not recommend using natural gas, diesel, or electricity, as even a dryer with a capacity of 1 ton/hour requires a significant amount of heat. To reduce energy costs, we suggest using wood chips or wood pellets, which provide stable heating and have lower drying costs.

Step 4: Use a coffee grounds briquetting machine to press fuel briquettes.

The coffee grounds briquetting machine is a biomass briquetting machine specifically designed for coffee grounds or coffee husks. When choosing a machine type, you need to consider your primary market. If your products are for residential heating, the standard briquette size is 70 mm in diameter and 30 cm in length. If your customers are mainly industrial boiler users or biomass burners, then you will need to produce briquettes with a diameter of 20-40 mm, with the natural breaking length being sufficient.

Step 5: Use a mesh belt cooler for rapid cooling, then package the coffee briquettes.

Although the coffee ground briquette machine has cooling line of about 10-20 meters, if you want to package the produced coffee briquettes quickly, it’s best to add a mesh belt cooler. This cools the briquettes or granules to near room temperature during transport and removes excess moisture from the surface of the briquettes through convection airflow. Therefore, the packaged coffee grounds can be stored for a long time without crumbling.

WHAT ARE THE ADVANTAGES OF COFFEE GROUNDS AND COFFEE HUSKS BRIQUETE?

High calorific value and long burning time. Coffee grounds have a calorific value between 4000-4500 kcal, and the briquettes density can be between 1.1-1.3 g/cm³, making it an excellent biomass fuel.
Safe and non-toxic, suitable for household use. Coffee husks and grounds briquettes are a pure natural green fuel, environmentally friendly, and contain no chemical additives (even if mixed with sawdust). Therefore, it is a lower-cost renewable fuel resource.
Low processing cost and considerable profit. Coffee husks and grounds are byproducts of coffee production, with extremely low acquisition costs. Coffee husks, in particular, require no crushing or drying, resulting in low processing costs and higher profits at the same selling price.
