Top 5 Commercial Coffee Roasters

Coffee Roasting Place

Around 1650, a cylindrical roaster was invented in Cairo, allowing roasting large portions of coffee. Soon, the innovation was adopted in France, Holland, Italy and other European countries.

In the 19th century, many commercial roasters designed for mass roasting of coffee were patented. With the history flow, their features have suffered basic innovations what has led commercial coffee roasters to the appearance more familiar to us. And below we want you to see the best candidates to be the best commercial coffee roaster machine.

KALDI WIDE size (300g) Home Coffee Roaster

We would definitely recommend this commercial coffee bean roaster to someone who doesn’t need or want computerized roast-profile management.

It is designed to sit on a gas burner. You control the flame. Fit and finish are A+. 

When the probe is inserted radially into the drum most of its length, temperature readings (in Celsius) correspond accurately to roast depth.

Easy to use with the funnel attachment. For the funnel to connect properly to the drum, the port of the drum must protrude about 1/4 ” proud from the face of the chassis, so that it sits on the two roller bearings. If you need to make an adjustment here, turn the unit over, and you’ll see a Phillips-head set screw on the shaft that will allow you to slide the drum a tad on the shaft. Remember to retighten the screw.

Gene Cafe CBR-101 Home Coffee Roaster

One of the best commercial coffee roaster can easily and smoothly change the temperature of roasting green grains, which allows you to build a roasting profile quite flexibly. Through the glass container, you can maximize visual control of the roasting process. Thanks to the original solution of the installation of the drum, the coffee is mixed very efficiently, and the result is an even roasting of beans.

The Gene Cafe is, from all appearances and experience, well built and has some ingenious engineering. The off-axis drum rotation results in very even roasts. The aesthetics are appealing.

We have seen some negative commercial coffee roaster reviews where users express frustration at poor roasting results, but from what we can tell these people seem not to have done proper due diligence before undertaking what is by no means a self-explanatory hobby. 

The smells and sounds of yellowing, the Maillard reaction, first crack, caramelization, and second crack are all quite enjoyable to learn how to respond to. 

There is a full manual mode where you can determine the amount of temperature to apply via the thermal elements (0%, 25%, 50%, 75%, or 100%),toggle the speed of the roast drum (8 RPMs or 16 RPMs) to simulate airflow change, as well as two thermocouples (one in the roast chamber and another that measures the exhaust temperature) so you can gauge the temperature curve of your roast and respond accordingly.

A great example of small commercial coffee roasters. This rudder mobile device is probably a long wide high dimension is 26.5 x 25 x 22 (cm), accounted for just a stove burner size, not too big, suggest baking and the amount of not more than 250 grams of beans, as long as the speed is too slow, beans quality is no problem, the uniformity is guaranteed.

Enthusiasts and coffee geeks achieve great success with this best commercial coffee roaster! Some people roast coffee on the balcony and become superprofessionals, others provide their coffee shop with freshly roasted coffee, while others use LANTAO as a sample roaster in production.

What is a Commercial Coffee Roaster

For exact observance of the temperature-time regime of roasting and for uniform mixing of coffee beans, a special apparatus is produced: coffee roaster. It works on electricity and gas, are drum and bowl-shaped, control can be semi-automatic or fully computer. Small home roasters can roast at a time from 100 grams of green coffee bean, huge industrial sometimes several tons at once.

 

The first commercial roster was patented in 1824 in England. The first devices were uncomfortable. The roster included a huge iron cylinder that rotated either inside the furnace or over an open fire. To get the grains, it was first necessary to remove the heat source – manually remove the hot cylinder from the furnace or move it away from the fire and pour coffee out of it.

The process required several workers and did not allow frying large volumes. The most popular roster of this type was the Carter Pull-Out Roaster.

How to Choose a Commercial Coffee Roaster

In answer to this question, experts agree on a common opinion – a mini-device (sample model). One run involves frying 60-300 grams of the product. The unit is often equipped with a control panel, with the help of which every coffee lover manages to set the necessary settings, including the time for roasting coffee beans.

The minus of the sample model is the high cost (from $300).

 

If we compare the convection and drum devices with each other, in the first case, less time is required for frying. Considering which roster to choose among the presented varieties, the best will be combined equipment.

According to experts and numerous commercial coffee roaster reviews, the advantages of the drum and convection devices are collected in it, and there are no disadvantages. For example, a drum roaster compares favorably with a built-in forced ventilation system. The hot air heats the grain product and takes out tiny specks through the ventilation pipe into the tray.

Commercial Coffee Roaster vs Home Coffee Roaster

Until recently, the so-called sample-roasters intended for roasting small quantities of grains were used mainly in industry. With their help, it was determined whether to purchase a particular batch of coffee. Home roasters do not require very precise roasting. But these devices are mainly used by professional roasters: for home, sample models are too expensive, and their performance is excessively high.

Roasters with electric motors and gas burners are more economical than electric ones: gas is cheaper than electricity. It is believed that with careful use the burner will last up to 30 years (although no one guarantees that the engine will not break down during this time). There are models that can work both on natural gas and on propane or butane.

However, control of a gas roaster requires some experience. The fact is that when the coffee is heated, moisture is released that reduces the temperature of the grain (ROR – Rate Of Rise). A particularly intense release of moisture occurs at the time of the first crack. Accordingly, grain temperature decreases sharply. In a gas roaster, it is difficult to achieve a smooth decrease and the same gradual increase in the temperature of grains.

An electric roaster is heated with the help of a heating element. The average service life of the heating element is 5–6 years. Grains in electric roasts are fried evenly. The temperature can be reduced and raised smoothly. However, it is difficult to achieve a sharp change in temperature, so some models are considered less manageable than gas counterparts.
