The large commercial hot air coffee roaster has the following features:
High heating efficiency and fast roasting speed: By using a blower to draw in air and heat it, the coffee beans are evenly heated through thermal convection. This can heat green beans to the required temperature in a relatively short time, improving roasting efficiency and meeting the demands of large-scale production.
Uniform heating: The coffee beans are constantly moving in the hot air roaster, and the hot air can evenly wrap each coffee bean, effectively avoiding the situation where some coffee beans are overheated or underheated, ensuring the consistency of the roasting quality.
Flexible temperature and air flow regulation: The heating method can be adjusted according to different baking requirements. By controlling the air flow speed and direction as well as regulating the temperature, the baking process can be precisely controlled to achieve diverse baking effects.
Suitable for highlighting the acidity of coffee beans: Compared with drum roasters, hot air roasters can better highlight the acidity of coffee beans, making the roasted coffee have more acidity and fruity flavors.
It has a good effect on removing the silver skin: Before the roasting room reaches the burning stage, it can effectively remove the silver skin from the roasting room, avoiding the coffee beans having a burnt and bitter taste.
Energy conservation and environmental protection: There is no need to preheat the baking machine. Each baking can save energy, and there is no open flame, no combustion, and no smoke, greatly reducing the emissions of hydrocarbons, CO₂, CO and SO₂, meeting environmental protection requirements.
The initial start-up cost is relatively low: Compared with some other types of roasters, the initial start-up cost of large commercial hot air coffee roasters may be lower, but the maintenance cost may be higher because some moving parts may need to be replaced regularly.
The operation is relatively simple: The equipment is easier to operate, and training employees becomes less complicated, which can reduce the requirements for the skills of operators.
Low environmental impact: Utilizing clean energy, it is safe and efficient, meeting the environmental protection requirements of modern industry.
