Types of Coffee Roasters
Coffee roasting machines are tools used to roast green coffee beans, and they come in different sizes. They are designed for commercial and personal use. Various types of coffee roasters include drum roasters, air roasters, and convection roasters.
-
Drum Roasters:
When looking at a coffee roasting drum machine, one may notice that it is somewhat cylindrical and rotates around a fixed horizontal axis. The shape of the drum is similar to that of a kettle drum, and as it turns, green coffee beans placed inside the drum begin to rotate and change temperatures. The drum then moves the beans inside the drum, creating a swirl. This brings the coffee beans in contact with the heating surface, thus roasting them.
-
Air Roasters:
Air roasters, also known as fluid bed roasters, use hot air to roast coffee beans. They have perforated roasting chambers where green beans are lifted by a stream of hot air. As the beans circulate, they get roasted. Air roasters are usually compact and suitable for home use.
-
Convection Roasters:
Just like air roasters, convection roasters use a combination of hot air and heated surfaces to roast coffee. In these types of coffee roasters, the roasting process is controlled by the transfer of heat. Convection roasters are known to produce a more uniform roast compared to other roasters. This is achieved through the proper transfer of heat throughout the roasting chamber.
Function and features of shop coffee roasters
Coffee roasting machines come with different features depending on customer preferences and budgets. Here are some of the common features:
- Cooling tray: It's a container that fastens the coffee cooling process after roasting. The cooling tray uses a blast of cold air to cool the coffee beans. The cooling process is important because it prevents the beans from over-roasting. Additionally, the cooling tray separates the chaff from the roasted beans.
- Power generator: Coffee roasting machines use different energy sources to operate Power line(roasters require a 220V power supply), propane gas, and wood. Electric roasters are popular among first-time roasters because they are easy to use. Commercial roasters use gas-powered roasting machines because they are cost-effective and have higher BTU per hour. Propane coffee roasters also have the added advantage of being mobile. While some artisan coffee shops use wood to roast coffee, the method isn't popular because it can cause smoky flavors in the beans.
- Roast profile controller: This advanced coffee roasting machine has two controllers: a PID controller for bean temperature precision and an Atlas controller for monitoring and adjusting the roast profile in real-time.
- Smoke separator: The smoke separator is an important commodity in the coffee roasting industry. It is a legal requirement for coffee roasters with a capacity of over 5 kg. The separator collects and filters the smoke released during roasting. In turn, it minimizes air pollution by converting the smoke into liquid that can be disposed of easily.
- Crushers: Large-scale coffee producers use oil crushers to extract oil from roasted coffee beans. The oil is then refined to make cooking oil for retail sale.
Applications for coffee bean roasting machines
There are many coffee roasting machines on the market, and various industries and applications use them in order to produce fresh coffee. The following are the primary applications for coffee roasters:
- Cafes and coffeehouses: Coffee bars and cafes are the biggest consumers of local green coffee beans. They utilize coffee roasters to prepare various kinds of coffee for their patrons.
- Small scale commercial production: Small businesses use shop coffee roasters to create packaged roasted coffee for sale in stores or online.
- Restaurants and hotels: These establishments utilize coffee roasters to prepare coffee for customers during breakfast, dessert, and dining.
- Corporate offices and facilities: They frequently utilize coffee roasters to produce brewed coffee for workers and guests.
- Specialty coffee retailers: Some retailers concentrate on providing coffee roasting equipment as well as selling freshly roasted coffee.
- Research and educational institutions: Organizations that study or teach about the coffee industry may have coffee roasting equipment for use in experiments or hands-on training.
How to choose a shop coffee roaster
When choosing a coffee roaster, it's essential to consider factors like batch size, heat source, level of control, material, and cooling method.
The batch size of the coffee roaster determines how much coffee the machine can roast in one go. If looking for a machine to use at home, a 1-pound or less capacity is ideal. On the other hand, a commercial coffee roaster machine will be an excellent option for businesses and shops since it can roast 5 pounds or more in one batch.
Heat source is another crucial factor to consider. Coffee roasters that use gas burners are more energy efficient than those that use electricity. Additionally, gas burners have lower operational costs. However, most small-scale coffee roasters use electricity to roast coffee.
When looking to control and get more information about the coffee roasting process, using a sample coffee roaster with a digital display is the ideal option. It provides real-time updates on different parameters of the roasting process, such as temperature and roasting time. The more advanced coffee roasting machines have automatic controls that simplify the roasting process. They can adjust various parameters to ensure consistent and precise roasting results.
Another factor to consider when choosing a coffee roaster is material. Most coffee roasters feature stainless steel or drums made from natural metals like copper and aluminum. The stainless steel coffee roasters are durable, resistant to rust, and require minimal maintenance. When it comes to copper and aluminum roasting drums, they offer excellent thermal conductivity for even heating. However, they may need more maintenance because they are prone to rust.
Lastly, consider the cooling method of the coffee roaster. Some models come with a built-in cooling tray for quick cooling. On the other hand, additional cooling equipment like a fan or open air is used in shop coffee roasters. The roasted coffee cools down quickly in the open air, but businesses will need to invest in additional cooling equipment for the coffee roaster.
Shop coffee roaster FAQ
Q1: What type of energy source is better for small coffee roasters?
A1: Gas-powered roasters are popular among small business owners due to their affordability and efficiency. However, electric coffee roasting machines provide better control over the roasting process and consistency in flavor profiles.
