To drum-roast or air-roast? Posing that question vacated could evoke a spirited debate among coffee roasters anywhere.

Since the outstart of coffee roasting, people have been frying and sizzling coffee beans with an unshut flame over hot metal. In other words, for as long as coffee has been around, pulsate roasting has traditionally been the go-to method to transform untried coffee beans’ chemical and physical properties into roasted coffee products. However, the increasingly modern approach, hot-air roasting, has wilt the preferred heat transfer system for many roasters today. As it suspends the coffee in a convection current of hot air, the heated air can envelop every single stone evenly, resulting in an plane and resulting roast.

What’s so unconfined well-nigh hot-air roasting? Is it really the weightier method?

Consistent stone temperature and stratum of roast

Hot-air roasting is favored for its precision in results. This is thanks to the fact that this method produces an plane roast, not only between the coffee beans, but moreover inside the individual bean. Meaning that coffee roasted in a convection (hot air) roaster will have a uniform verisimilitude from the outer layer all the way to the core. Plane if they desire to take it to the whet of savor development, they won’t compromise the clean, sweet flavors (i.e. no need to worry well-nigh scorching). This differs from a pulsate roaster, where the coffee is roasting on hot metal. The bean’s outer layer can heat too fast resulting in an uneven verisimilitude inside the bean.

Consistent sweet, wipe flavor

Different roasting methods requite variegated results. Traditional pulsate roasting operates with a higher conductive heat transfer to make the chemicals react. It roasts the beans from the outside, known to leave you with a thicker savor regardless of the origin of the coffee. Drum-roasting your beans will develop a heavier, sometimes oilier, and denser taste. This savor profile may not be sought-after, but this method will unchangingly hold a soft spot for traditionalists.

On the other hand, Hot Air Roasting utilizes 100% convective heat transfer to hoist the aromatics in coffee. Convection roaster keeps the coffee beans moving and rotating with a perfectly controlled hot air spritz to produce an plane roast. During the process, hot air forces out of the satirize that would otherwise shrivel into the beans and mask the true profile. The end result is a clean, smooth taste that many coffee drinkers love. Roasters and drinkers who have tasted hot air roasted coffee beans can attest they can taste the noticeable resurgence in savor to drum-roasted beans.

Hot-air roaster allows a increasingly precise Between Batch Protocol (BBP) by taking yonder one parameter that has unchangingly been a guesswork in a traditional pulsate roaster: pulsate surface temperature. It is virtually untellable to measure pulsate surface temperature in a traditional pulsate roaster, but this measurement is unnecessary in a hot-air roaster since the pulsate is never directly heated by the burner. This way, the roaster can hands indistinguishable batches of coffee beans, recreating the same color, savor profiles, and aroma.
