The birth history of coffee roaster-concentrated roasted coffee beans

The birth history of coffee roaster-concentrated roasted coffee beans

1. Direct fire type inner pot

The principle of coffee roaster is introduced by DISCOVERY.

The inner pot has been punched,

The burner flame at the bottom comes into direct contact with the coffee beans.

The direct-fire flavor is attached to the coffee,

Into fragrant and delicious coffee.

The flame and heat of the burner are the main heat sources of baking.

2. Semi-hot air inner pot

The principle of coffee roaster is introduced by DISCOVERY.

The inner pot is made of iron plate.

The rear part of the inner pot is punched,

Hot air is introduced as a result.

It is important to control the firepower of the burner below and use the exhaust valve to regulate the convection of the air in the pot.

3. Semi-hot air double inner pot

The outer side of the iron plate of the semi-hot air pot is then wound with a layer of iron plate,

An inner pot in which an air layer is formed between the iron plate and the iron plate.

Raw beans do not come into contact with iron plates that are heated by the flame heat source of the burner below.

It is the inner pot that has attracted much attention and been consulted by many parties recently!

4. Far infrared surface coated inner pot

Apply far-infrared surface coating to the inside of the direct-fired inner pan.

The roasted Zhongyuan infrared ray shines directly on the coffee beans.

The tar covered with coffee on the inner pot can also be exposed to far infrared light.

With a strong radiation source, it can easily penetrate into the interior of the coffee.

The exhaust of the coffee roaster

An indispensable exhaust system for coffee roasting.

It is also the most nerve-racking part from the beginning of using the roaster.

The function of exhaust function of roaster

■ exhaust smoke.

When coffee is roasted, it produces a lot of smoke.

If the coffee in the baking is too exposed to the smoke

It will give the coffee a strong smell of smoke.

Infrared generating device installed on the side of the inner pot

Bake coffee from the heat source of the gas burner below and the radiation heat source from the side.

A roaster with very little demand.

The heat source corresponding to high-quality coffee,

I hope to get everyone's attention in the future.

Characteristics of inner pot

FUJIROYAL coffee roaster currently has 4 kinds of inner pots!

Of course, the taste of coffee does not matter, and the use of coffee roaster is different.
