Advantages of a Home Coffee Roaster Machine​

Home Coffee Roaster Machine Benefits

Are you part of the many coffee drinkers who are quick to grab a bag of pre-roasted whole beans or coffee grounds off their local grocery shelf without considering getting something better? If that's a resounding yes, knowing the different advantages of roasting your beans at home will turn into a coffee lover that will never settle for mediocre roasts from your local supermarkets again.

The following are the different benefits that come when roasting your beans at home:

  • Cost-Effective - Purchasing raw green coffee beans cost less than buying pre-made roasted coffee.
  • Fantastic Flavors - Coffee roasting will give you the freshest roasts, helping your favorite beans reach their maximum potential, rewarding you with the best cups around.
  • Better Control - When you roast beans at home, you are given full control of how the beans are prepped, matching the roast profiles to your liking.
  • Variety - When you buy pre-roasted beans at your grocery stores, your options are limited, and you often find yourself settling for commercial blends. However, roasting beans at home lets you roast an array of beans.
  • Caffeine Level - There are limited choices when it comes to decaffeinated roasts in the market. You can create roasts that suit your tastes when you roast coffee at home.

Is Roasting Your Own Coffee Worth It?​

If you are the type of person to appreciate the freshness and flavor of coffee, roasting your beans at home is worth the time and effort. When you roast your beans at home, you are rewarded with the freshest and most flavorful cups, ultimately letting you enjoy your favorite coffee thoroughly. These homemade roasts can last up to a full week, retaining its robust flavors for the best morning fixes.

How Much is a Coffee Bean Roaster?​

The prices of these roasters depend on the volume of beans you need to process or your specific needs. Small automatic household coffee roasters like the JIAWANSHUN hot air roaster machine are available for less than $400. Manual roasters like the Kaldi wide roasters can cause up to $600, but you need to purchase separate gas burners for manual roasters like those from Kaldi, which can rack up your costs to over $900.

However, if you want to produce more roasts in one sitting or have more advanced features like smoke suppression technology and infrared radiation technology, you can opt for roasters like Bocaboca's Bean roasters, which ranges from $600 to $900.

How Do You Make a Coffee Roaster at Home?​

Grab a heat gun, a metal container, such as a stainless steel metal colander or a simple metal mixing bowl, and a stirring utensil like a large metal spoon.You need to place about one pound of green coffee beans in the metal container, set the heat gun at the lowest heat setting, place its nozzle one inch above the coffee beans, and begin stirring them using your stirring utensil. When its green color disappears, you can increase the heat to drive the first crack, and continue until you reach your preferred roast profile.

Another method of creating a homemade roaster is by converting your popcorn machine into a coffee roasting machine. It is perfect for roasting coffee as it can heat the beans in a confined area to a temperature exceeding 450 degrees Fahrenheit, making it the ideal temp for the coffee beans.

How to Use a Coffee Bean Roaster​

Steps on How to Use a Coffee Bean Roaster

If you have roasters that have built-in heat sources, here are the following steps in using roasters that do not require a heat source:

  1. Grab the freshest green coffee beans you can.
  2. Place them inside the roaster's container and close the lid.
  3. After securing the top, turn on the machine.
  4. Adjust the levels and temperature when necessary.
  5. Wait for the beans to reach your desired roasting point.
  6. When the roasting process finishes, open the lid and hang the lid handle on the groove.
  7. Take the beans out and place them into a wicker tray.
  8. If the machine has a built-in cooler, you can place them inside it. However, if it does not have that feature, shake the tray until the beans have sufficiently cooled off.
  9. When they have completely cooled, take the chaff gathered under the tray and dispose of it.
  10. Store the beans inside an appropriate container and leave it overnight to degas.
  11. After the 24 hours, enjoy your fresh roast.

However, if you have roasters that require separate heat sources, follow these steps:

  1. Place the green beans inside the machine, and most manual roasters do not have smoke suppression technology, so ensure you have proper ventilation.
  2. Place the roasting appliance to a heat source, such as a gas burner or an electric stove.
  3. Turn the heat up and let the machine do its work.
  4. If you want to get the perfect roast and do not want a mixture of light, medium, and dark roasts, make sure to check the temperature using a thermometer.
  5. Continue to let the beans roast until they reach your desired roast level. For a light roast, remove the device from the heat source before the first crack, which happens between 356°F or 401°F. Medium roasts occur between 410°F or 428°F, and Dark roasts between 437°F or 482°F.
  6. Never let the beans roast above 482°F, because it will thin it out and create a burnt or ash-like taste.
  7. Separate the chaff from the coffee beans and let it cool before storing it. You can use a colander or the machine's built-in chaff collector to separate these two components.
  8. Store the beans inside a non-airtight container overnight, allowing the freshly roasted beans to degas.
  9. After 24 hours, you can now grind your beans and enjoy your coffee.

Tips on Using Manual Coffee Roaster

Although many roasters have opted for automated versions, using a manual coffee roaster is still a great way to roast coffee beans. The best part is, you get to have full control of the whole process, giving you results tailored to your tastes. There's no single way to ensure consistent results when roasting beans, but there are several ways you can achieve consistent roasting for the best outcome.

The following are some tips to consider when using manual coffee roasters—helping you achieve better results at home every time.

  • Understand Heat Transfer
    A significant component in ensuring better coffee roasting using manual roasters is understanding how heat transfer works in these machines. For instance, there are two primary sources of heat transfer in your standard drum roasters—conductive and convective. A conductive transfer is when the heat gets transferred directly between the drum and beans, while a convective transfer is heat caused by airflow as beans get tossed around in a hot drum.

    Know what your specific roaster uses and adjust the frequency you add in green coffee beans to ensure even heat transfer throughout the beans, allowing you to achieve your desired roast curve every time.

  • Always Preheat Roaster
    Preheating is crucial in a smooth and faster roasting process. That's because if you don't preheat the drum at the correct temperature, you'll get less conductive energy to transfer to your beans, resulting in an uneven and less-than-ideal product. So, when using your manual roasters, make sure to preheat at the designated temperature in its instructions. Having an adequate warm-up cycle at the start of production is one of the 'essential checkpoints' roasters need to be attentive to when manual roasting.
  • Standardize Between-Roast Routine
    When you're roasting manually, there's no series of disconnected S-curves, but instead, it produces a continuous wave. So, to keep these uniform and consistent, you need to keep the times between each roast you make identical. How you reheat your roasters between each session is essential, and your point of control is dropping roasted coffee.When you finish a batch and drop them into your cooling tray, you're essentially releasing an ample amount of heat. It's crucial to standardize how long it takes to empty each one before heating the next one. So, focus on ensuring that it's open for the same amount of time for each roasting batch.
  • Understand the Roaster's Convective Heat Flow
    Whatever manual roaster you're using, it'll virtually interact with the air outside of it, taking in the cool air and expelling the hot air. How much and how well your roaster does in roasting beans relates to your convective heat transfer. The device's 'breathing' is crucial, especially after the first rack, when you lower your flame and rely on consistent hot air for even roasting. Some models have built-in valves to adjust airflow, which you can use to control the convective heat flow.However, keep in mind the other factors that may affect the process, such as the weather and the amount of chaff your collector has.
  • Continuously Agitate Beans
    One crucial tip that many roasters neglect, thanks to automation, is agitating the beans. Agitation is essential in keeping the beans uniformly roasted. After all, beans should never rest and roast. So, make sure to continually stir the beans to ensure uniform distribution of heat, providing better and delicious roasts.

How Long Does it Take to Roast Coffee Beans?​

The roasting times do vary depending on the method you use and batch sizes. However, roasting coffee beans using modern roasters takes between 10 to 13 minutes for small batches, and if you want to make more substantial quantities of cooked coffee beans, it will take you about 16 to 18 minutes. However, considering all the factors, the average time it will take to create freshly roasted coffee beans can take over 20 minutes of your time.

Why You Should Use a Small Batch Coffee Roaster​

Coffee beans are fragile, and they quickly deteriorate after roasting. That's why you may notice that instant roasted coffee at grocery stores has a lighter aroma. These beans typically lose their aromatic qualities after you leave them to sit for five days. Roasting in larger batches is the main reason for this, as it can degrade the coffee fast.

It would be best if you opted for a small batch roaster as roasting in smaller batches prevents the degradation of your roasts, this helps you produce enough high-quality beans to last through your drinking cycle, preserving its full flavor.
