What is a coffee roaster and how does it work?

Everything, from raw bean to warm cappuccino,  influences the final product making coffee. Roasters are no exception. Modern technology changes the game but fundamental processes stay the same. Even using automated technology, commercial roastmasters make quick decisions during roasting. With few standardizations for different roasts, it becomes an individualized experience. Going on your own journey is a learning process to curate your unique coffee style.

What is a coffee roaster?

To understand what a coffee roaster is, first know what it does. Roasting is cooking beans: shaping  flavors for consumption by manipulating physical characteristics. Finding a roasting method is integral to good coffee.

There are many kinds of roasting machines and methods. The most common are drum or hot air machines. Otherwise, you may find packed-bed, tangential, or centrifugal types. Today, hybrid machines provide many automated operation modes in one appliance.

How does coffee roasting work?

Coffee roasting works in many different ways. Today, many emerging methods popularize rapidly. In each process, the same basic fundamental steps are true:

  1. Turn up the heat! Preheat the drum, start hot airflow, or spark an open flame to take moisture out of your raw beans.
  2. Get your green beans. Fill your drum, cylinder, or plate with desired volume of beans. Different roasters have different capacities, so pay attention to ensure an even roast.
  3. Let them dry. Beans will dry in five to eight minutes. Either the beans or hot air circulate to evenly roast avoiding defect or scorching. Their color ranges from a light yellow to brown and smells like fresh popcorn at this point. Note that around 7 minutes in, the beans expand like popcorn as well.
  4. Cool them off. Transfer beans to a sieve or tray to cool keeping their freshness. A destoner is sometimes used to remove stones or other defects that come in green beans.
  5. De-gas and develop flavors in packaging, even during shipment. Either way, the coffee should rest for a few days.

Operating modes of a Typhoon Roaster

Typhoon Roasters automate and log from beginning to end. Roastmasters control the airflow, mixer speed, temperature, and dampers on a simple interface. Repeat roasting profiles precisely and combine methodologies like never before.

Hybrid technology allows interchangeable convective and conductive heat supply with one machine. In convection, heat transfers through hot air. This creates acidity and bright flavors along less contact and less cleaning. Conduction uses a heated object, such as the drum, to make dense coffee and sweet flavors. To switch between the two, change the surface plate and install the mixer. Simultaneous methods can combine and easily adjust at any point during roasting. Typhoon Roasters add flexibility and freedom to your roast by incorporating revolutionary technology. Our fluid-bed techniques keep up on state-of-the-art, hybrid technology.

Are hybrid technologies right for your roasting business?

Hybrid technologies have undeniable advantages. Even so, always consider your business’s needs to cater to. Think of how you will use the appliance, what you can afford, and how safe it is for you and others. This can help you decide the best roaster for you.

Drum roasters are consistent, even, and difficult to clean. They are the most pricey machines despite having only a conductive heat option. The barrel rotates, through which external heat cooks mobilized beans. Fuel machines are mostly drum roasters for commercial use.

Hot air methods are second most common, but once again only offer one heating method. No-contact convection means these sometimes don’t even have a barrel. Hot air is more affordable and normally electric, but less common for large scale operation.

For an affordable and flexible roaster, hybrid technology is the way to go. Any percentage of conductive and convective heating simultaneously applies. Adjust at any point during the roast. Manufacturers like Typhoon Roasters include state-of-the-art ideas like fluid-bed roasting in hybrid technology. Built-in automation and precision lets the machine’s memory pull and replicate roasts.

With so many coffee roasters, the choice is daunting. Finding a machine that meets personalized operation standards affordably can be difficult. To choose the right path in your coffee journey, consider your options with revolutionary hybrid roasters.
