Coffee roasting machine is the commonly used coffee bean baking equipment, it can be commercial type and household type. Taizy coffee roaster machine is specialized in manufacturing the shop-use or household coffee roasting machines.
This coffee roasting equipment can bake coffee beans with even heating methods and the whole roasting process is smokeless and very efficient.
Why should we bake the coffee beans with a coffee roaster?
We are all familiar with all kinds of coffee and most of us like to drink coffee every day. But about how is the coffee powder made, we know very little. When the coffee beans are harvested, they should be shelled for separating the kernels and shells by the special coffee bean shelling machine. Then the cleaned coffee beans should be baked at a temperature of about 170℃ in the coffee roasting equipment. The coffee roasting process is mainly to remove the excess moisture and cause a series of chemical reactions, such as Caramelization reaction and Maillard reaction, which can turn the raw coffee beans into scented coffee beans.
Main structure of the coffee beans roaster machine
The commercial coffee roasting machine can be designed with the two heating ways: liquefied gas heating and electric heating. It’s worth noting that it is better to choose the liquefied gas heating if the processing capacity is more than 6 kg/h for it will not cost much. And if your processing requirement is lower than 6 kg/h, you can choose both of these two heating methods. The coffee beans baking machine is composed of the feed hopper, electric control cabinet, baking chamber, sampling spoon, observation port, dust collecting device, fans, cooling plate, 4 motors, adjustment handle, access door, and the discharge port.
The parts contacting the coffee beans are made of the carbon steel which has very good thermal conductivity, and they can also be designed with stainless steel based on customer needs. The coffee roaster is equipped with two sensors: one at the exit of the baking chamber to measure the temperature of the baking chamber, and the other at the damper to measure the temperature at the damper to adjust the damper switch according to the temperature to adjust the temperature in the baking chamber.
How does the coffee roasting machine work?
When using this shop coffee roasting machine, we should preheat the roasting chamber to reach the baking temperature of about 160℃-170℃by by electric heating or gas heating. When the temperature is ready, add the raw coffee beans into the feed hopper with a certain amount. This coffee roasting machine is the batch processing type, and it can bake the coffee beans for about 3-4 batches in each hour.
During the coffee beans roasting process, the coffee bean shells and the evaporated water will be extracted from the dust collector device. Each batch of coffee beans roasting will last about 15-20 minutes, and we can observe the baking degree of the coffee beans through the observation port or by the sampling spoon. When the coffee roasting is finished, we can open the discharging baffle and the baked beans will fall down into the cooling port. There are the mixing shafts of the cooling port for stirring the coffee beans so that the coffee beans’ temperature will be cooled with lower than 70℃quickly.

When this wet coffee fruit peeling machine working, the coffee fruits will be peeled fast and can be simply washed for getting the clean coffee beans. This peeling machine can be the electric drive or diesel engine drive with various types and models, and it’s processing capacity ranges from 800kg/h to 4500kg/h.
2. Dry coffee bean shelling machine
This sheller machine is mainly to remove the thin layer of endocarp attached to the coffee beans. During the shelling process, the clean coffee beans will be discharged from one outlet, and the coffee bean skins will be discharged from the other outlet. The peeling rate can reach 90%, and the coffee bean sheller machine’s yield ranges from 150kg/h to 2800kg/h. It also has different types and models.
