How to Properly Adjust Wood Pellet Machine Temperature for Beginners？

Dec 25, 2025

Operating steps

Step 1: Identify the raw material type and determine the basic temperature range (key for beginners: identify the type first, don't experiment blindly). Beginners can refer to this basic table: softwood chips 75-85℃, hardwood chips 90-105℃, straw 85-95℃. For example, if a beginner is processing pine chips for the first time, set the temperature to the middle value of 80℃. This is the safest initial setting and has a high probability of successful pelletizing.

Step 2: Preheat the machine and wait for the temperature to stabilize. Turn on the power to the biomass wood pellet mill and start the heating system. Do not feed the material immediately. Let the machine idle and preheat. After the temperature reaches the set value, maintain the preheating time for 5 minutes to ensure uniform temperature inside the pressing chamber. A common mistake for beginners: feeding the material as soon as the temperature reaches the set value. At this time, the temperature inside the pressing chamber has not yet stabilized, resulting in poor pellet formation. For example, set the temperature to 80℃, wait for 5 minutes after the temperature display reaches 80℃ to allow the pressure rollers and molds to heat up fully before feeding the material.

Step 3: Test process and observe, fine-tune the temperature.

First, maintain a uniform, low-speed feed and test-process the electric flat die pellet mill for 10-15 minutes. Collect the produced pellets and judge them from three dimensions: feel (whether they are hard and smooth), appearance (whether there are cracks or carbonization), and molding rate (whether they crumble easily when squeezed). If the pellets are hard, smooth, and without cracks, the temperature is suitable; maintain this temperature. If the pellets are loose, the temperature is too low; increase it by 5°C each time and test-process for another 10 minutes. If the pellets are carbonized, the temperature is too high; decrease it by 5°C each time until the target temperature is reached. New users should remember: adjust only one parameter at a time (only the temperature); do not adjust both the temperature and feed rate simultaneously to avoid difficulty in identifying the problem.

Fourth step: Stabilize production and monitor in real time. After adjusting the temperature, maintain a uniform feed rate and check the pellet quality and the temperature display of the Wood pellet manufacturing equipment every 30 minutes. If fluctuations occur, make timely minor adjustments. For example, if the moisture content of the raw material slightly increases during processing, causing slight cracks in the pellets, increasing the temperature by 3°C will resolve the issue. Beginners should note: The temperature displayed on the equipment screen is the set temperature. If you suspect the temperature is inaccurate, you can attach a temperature test strip to the discharge port of the pressing chamber and measure the actual temperature to see if it matches the set value. This helps avoid abnormal temperatures caused by sensor malfunction.

Essential tip for beginners: Record the appropriate temperatures and adjustment processes for different raw materials in a notebook. Refer to this directly when processing the same raw materials next time; this will allow you to get started quickly and reduce trial-and-error costs.
