In terms of hardness, the quality of charcoal briquettes can be influenced by various factors, including the raw materials used, the process of briquetting, and the curing process. Within this article, we aim to provide you with several useful tips to produce charcoal briquettes that have a reduced likelihood of cracking!
Use high-quality raw materials
Using high-quality raw materials is indeed crucial for producing high-quality charcoal briquettes. Here’s a breakdown of the recommended raw materials and the role of binding agents:
Hardwood or Sawdust: Hardwood, such as oak, maple, or hickory, is commonly used as a raw material for charcoal briquettes. It provides a dense and long-lasting fuel source. Alternatively, sawdust from hardwood can also be used, ensuring efficient utilization of wood resources.

Binding Agent: To hold the briquettes together and maintain their shape during the manufacturing and burning processes, a binding agent is necessary. Commonly used binding agents include starch (derived from corn, wheat, or potatoes) and molasses. These agents act as adhesives, helping to bind the charcoal particles together.
When selecting raw materials, it is important to ensure that they are free from contaminants, such as chemicals or impurities that could negatively affect the final product’s quality or safety. Testing and quality control procedures can be implemented to verify the purity and suitability of the raw materials.
By using high-quality raw materials and appropriate binding agents, you can create charcoal briquettes that are consistent, efficient, and produce a clean and long-lasting burn.
Use the right amount of binder

The proper amount of binder is crucial for achieving high-quality charcoal briquettes. Here’s a guideline for using the right amount of binder:
Follow recommended ratios: Different raw materials may require different amounts of binder to achieve optimal results. It’s essential to follow recommended ratios or formulas provided by experts or manufacturers in the field. These ratios are often determined through experimentation and extensive testing to ensure the best performance of the briquettes.
Consider the moisture content: The moisture content of the raw materials can affect the binding process. If the raw materials are relatively dry, they may require a slightly higher amount of binder to achieve sufficient cohesion. On the other hand, if the raw materials are already high in moisture, a lower amount of binder might be needed.
Conduct tests and adjustments: It’s advisable to conduct small-scale tests before large-scale production. This allows you to assess the quality and performance of the briquettes. By starting with the recommended amount of binder and gradually adjusting it, you can evaluate the impact on briquette integrity, burn time, and overall performance. This iterative process helps determine the optimal binder quantity for your specific raw materials.
Consider environmental factors: Environmental conditions, such as temperature and humidity, can also influence the binding process. In high humidity environments, for example, a slightly higher amount of binder might be necessary to counteract the moisture present in the air.
Maintain consistency: Once you determine the appropriate amount of binder for your raw materials, it’s important to maintain consistency throughout the production process. Consistent binder proportions ensure that each briquette has the same level of cohesion, leading to uniform burning characteristics and reliable performance.
Use the right amount of pressure
Understand the raw materials: Different raw materials have varying characteristics and densities. Understanding the specific properties of your raw materials, such as their moisture content and particle size, can help you determine the appropriate amount of pressure required.
Optimize pressure levels: The ideal pressure level depends on factors such as the binder used, the composition of the raw materials, and the desired density of the briquettes. Applying too little pressure may result in loosely bound briquettes that are prone to breakage, while excessive pressure can make the briquettes overly dense and difficult to ignite. Conducting small-scale tests and adjusting the pressure gradually will help you identify the optimal pressure level for your specific materials.
Consistency is key: It’s crucial to maintain consistent pressure throughout the briquetting process. Inconsistent pressure may lead to variations in briquette density and integrity. Using a reliable briquetting machine or press with consistent pressure capabilities can help achieve uniform results.
Consider the briquette shape: The shape of the briquette can also influence the required pressure. Different machines may have specific recommendations for pressure levels based on the shape and size of the briquette being produced. Follow the manufacturer’s guidelines to ensure the appropriate pressure is applied for the desired shape.
Balance pressure with binder content: The binder acts as a cohesive agent that helps hold the briquette together. The amount of binder used should be balanced with the applied pressure. If the pressure is too high and the binder content is insufficient, the briquettes may crumble. Conversely, if the pressure is too low and the binder content is excessive, the briquettes may become overly compacted and less effective as fuel.
By using the right amount of pressure during the briquetting process, you can create well-formed, durable briquettes that maintain their shape and provide consistent burning performance.
Properly cure the briquettes

Properly curing the briquettes is a crucial step in the manufacturing process to ensure their durability and longevity
Timing: Allow sufficient time for the briquettes to cure and dry. The recommended curing time is typically between 3 to 7 days, but it may vary depending on factors such as the size and density of the briquettes, humidity levels, and temperature.
Dry and well-ventilated area: Choose a dry and well-ventilated area for curing the briquettes. Adequate air circulation is important to facilitate the drying process and prevent moisture buildup, which can lead to mold or mildew formation.
Avoid direct sunlight and rain: Shield curing briquettes from direct sunlight and rain to prevent interference with the drying process. Consider using covered drying racks or drying rooms to shield the briquettes from adverse weather conditions.
Maintain proper spacing: Ensure that the briquettes are spaced apart during the curing process. Sufficient spacing allows air to circulate around each briquette, promoting even drying and preventing them from sticking together.
Regularly check for dryness: Monitor the curing progress by regularly checking the moisture content of the briquettes. They should feel hard and dry to the touch when fully cured. Thicker or denser briquettes may take longer to dry compared to thinner ones.
Quality control: Conduct quality control checks during the curing process to identify any cracked or damaged briquettes. Remove any defective briquettes to maintain a consistent and high-quality final product.
Store the briquettes properly

Storing cured briquettes in a dry place is crucial to maintaining their integrity and preventing moisture-related issues. Here are some guidelines for proper storage:
Choose a dry storage area: Select a storage area that is dry, well-ventilated, and protected from direct exposure to moisture, rain, and humidity. Ideally, the storage location should have controlled temperature and humidity levels.
Avoid contact with water: Keep the briquettes away from any sources of water or excessive moisture. Even a small amount of moisture can impact the quality of the briquettes and lead to cracking or breaking.
Use appropriate containers or packaging: Store the briquettes in containers or packaging that provide a protective barrier against moisture. Plastic bags, sealed bins, or airtight containers can help maintain the briquettes’ dryness and prevent moisture absorption.
Elevate from the ground: If possible, store the briquettes on pallets or elevated surfaces to prevent contact with damp floors. This further minimizes the risk of moisture absorption.
Regular inspections: Periodically inspect the stored briquettes to ensure they remain dry and intact. If any signs of moisture or damage are observed, take appropriate actions to rectify the situation or discard affected briquettes.
Rotate stock: If you have a large quantity of briquettes, practice stock rotation to ensure that older batches are used first. This helps maintain the freshness and quality of the briquettes.
By storing cured briquettes in a dry environment, you can prolong their shelf life, maintain their structural integrity, and ensure they are ready for efficient use as fuel when needed.

By following these tips, you can make charcoal briquettes that are less likely to crack and break, resulting in a more consistent and high-quality product.
