Types of roasters for roasting boutique coffee
Direct fire, semi-direct fire (semi-hot air), hot air

At present, it is recognized that the machine which can most cause the flavor of coffee in the roaster, its source of fire has direct contact with coffee beans, so it can produce a better flavor of coffee beans, but its baking process has a great impact on the finished products. therefore, the roaster itself must have a certain foundation, but compared with this type of machine, it is also more able to produce different products.

Semi-hot air (semi-direct fire):
The semi-hot air type combines the advantages of direct fire and hot air, the flavor is more prominent than the hot air type, and the baking control is easier than the direct air type, but the relative quality is also medium.
