How to avoid chestnuts from cracking when roasting

Peanut roasting machine is a professional equipment for roasting nuts. It is easy to use and has high efficiency, and is widely praised by customers. When roasting chestnuts by peanut roasting machine, sometimes chestnuts crack, which deeply puzzles our customers. So how to avoid chestnuts from cracking when roasting chestnuts?

1. The easiest way is to open a small mouth of raw chestnut. Chestnut will crack because there is water in chestnut itself, and the internal water will expand into steam at high temperature, which will form an external pressure on chestnut shell. When the pressure is too great, chestnut shell will explode, so it is the most direct and effective method to open a small mouth.

2. When roasting closed chestnuts, it is necessary to control the heat of the roasted chestnuts. If the heat is too small, uneven heating may occur. If the firepower is too large, chestnuts will be unable to withstand the pressure and self-destruction, so it is necessary to control the size of the roasted firepower.

3. Control the rotation speed of the peanut roasting machine. When roasting chestnuts, there will be collisions between chestnuts. When the rotation speed of the equipment is too fast, the collision friction between chestnuts will double, and then the chestnut will crack. In order to avoid this situation, when roasting chestnuts, the rotation speed of the machine must be appropriate.

4. When the temperature is too high, the water inside the chestnut will evaporate and expand quickly, and then the chestnut will crack, so the temperature of the roasted chestnut must be controlled.

These are the ways to avoid cracking when roasting chestnuts.
