This creation is a round coffee roaster, especially a round coffee roaster with accelerated heat transfer and far infrared.

At present, the drinking habits of drinking coffee have penetrated into the public life and become a part of most people's lives, and various technologies such as coffee manufacturing and brewing continue to advance. Usually, the baking of coffee beans requires picking up the fruit of the coffee tree, removing the pulp, drying it, peeling it into green coffee beans, and then baking it to become a cooked coffee bean for cooking. Baking technology is an important factor affecting the quality of coffee. Therefore, the components of the coffee roaster and the materials used are also important factors affecting the quality of coffee roasting.

At present, the coffee roaster of the conventional technology has a complicated structure and a control motor, so that the price is extremely expensive, and when baking, if the stable baking effect of the roasted coffee beans is not good, the influence is seriously affected. The ripening of the coffee beans will cause the coffee beans to be baked for too long, and the coke and charcoal will occur. Therefore, the coffee roasters in the coffee roaster will directly affect the quality of the roasting of the coffee beans. At present, the materials used in coffee roasters in coffee roasters are mostly made of materials such as pig iron, steel, and glass. However, the use of pig iron or steel material may also cause the phenomenon of friction between the coffee beans and the fixed wall after a long heating, and even the phenomenon of structural cracking. The heat conduction effect of the glass material is poor, which consumes a high fuel cost. Therefore, the aforementioned conventional coffee roasters each have Its shortcomings require the development of new coffee roasters.

This creation uses the use of tantalum carbide as the first round roasting barrel in the industry, and the creation of a special round roaster for special coffee can make the coffee beans burst and mature at lower temperatures, so during the heating time This can be shortened, which in turn reduces the time required to roast coffee beans and also reduces fuel costs.

The round coffee roaster drum made by this product is made of tantalum carbide, which has the advantages of strong heat build-up, good heat storage and long-term heat preservation, and can emit far infrared rays which are not contained in other materials, so that the roasted coffee beans flavor It is richer, the level changes more, and the preservation period is longer.

Another purpose of the creation of the round coffee roasting drum is to enhance the richness and variety of the coffee flavor, and to generate far infrared rays during the heating process, and the far infrared rays promote the coffee beans during the heating process. The function of carbohydrate saccharification makes the aroma of coffee more high-spirited.

The round coffee roaster is a hollow circular structure. During its rotation operation, the round coffee roasting drum rolls in the axial direction of the roller, so that the coffee beans are evenly heated to achieve the roasted coffee beans. Features.

Therefore, the advantages and spirit of this creation can be further understood by the following details of the creation and the drawings.

1 is a side view of a conventional coffee roaster and a circular coffee roaster of the present invention; and a front view of a coffee roaster of the prior art and a circular coffee roaster of the present invention. .

Referring to Figure 1, a side view of a conventional coffee roaster, in addition to the main roasting unit, also includes a circular type coffee roasting drum 80 of the present invention. The foregoing baking unit comprises: a carrying body 10, which can carry the functions of installing various appliances. The heating device 20 is disposed on the carrier body 10. The cooling device 30 has a cooling function and is disposed on the carrier body 10. Feed device 40 has the function of providing a feed for coffee beans. The dust collecting and exhausting device 50 has a function of concentrating and discharging the gas generated during heating and flying dust. Roller 60 provides scrolling functionality. In the creation of the round coffee roasting drum 80, the round coffee roasting drum 80 is mounted on the roller 60 and combined with the aforementioned baking unit, the round coffee roasting drum 80 provides rolling, uniform heating to bake The function of coffee beans.

Referring to Figure 2, a front view of a conventional coffee roaster, the carrier body 10 is located at the bottom of the coffee roaster to carry the entire body. The cooling device 30 is located above the carrier body 10, and the circular coffee roaster drum 80 of the present invention is installed above the cooling device 30 as viewed from a front view. The position of the roller 60 is mounted at the center of the round coffee roasting drum 80. The feeding device 40 is disposed above the round coffee roasting drum 80.

The circular coffee roasting drum 80 of the present invention has a circular shaped barrel body, and the round shape of the circular coffee roasting drum 80 has openings (two openings) at both ends, the circular shape The barrel system is a hollow structure with the function of placing coffee beans. The creation of the round coffee roasting drum 80 is a hollow circular structure. During its rotation operation, the circular coffee roasting drum 80 is rolled in the axial direction of the roller 60, so that the circular coffee roasting drum 80 The coffee beans placed in the container inside the circular shape barrel can be uniformly heated to produce the function of roasting coffee beans.

The baking of the round coffee roasting drum 80 is made of tantalum carbide, so that the appearance of the round coffee baking drum 80 is dark brown. Since the round coffee roasting drum 80 needs to be sintered at a high temperature of 1300 degrees, and the firing shape is difficult to control, the process is quite difficult. When the round coffee roasting drum 80 is heated, far infrared rays are generated by the black body radiation effect, and the far infrared rays can penetrate the coffee beans. Since tantalum carbide has a low coefficient of thermal expansion and high thermal conductivity, it is suitable for the production of a circular coffee roaster drum 80 due to its low coefficient of thermal expansion (4.0×10 ^-6 /°C). The time is heated, so the circular coffee roaster drum 80 of the present invention has a function of releasing far infrared rays to roast coffee beans.

In addition, please refer to the following list (obtained from the website of Kallex Co. Ltd.): As shown in the above table, compared with iron and glass materials, tantalum carbide has a heat transfer coefficient of 126 W/m*°K, which is the crown of each material, so it has fast conduction efficiency, and the thermal expansion coefficient of tantalum carbide is 4 10 ^-6 / °K, which is an intermediate level in the performance of each material. Therefore, the choice of yttrium oxide as the material depends on the higher thermal conductivity of yttrium oxide and the lower coefficient of thermal expansion. The high heat transfer coefficient is advantageous for the coffee beans to burst and mature at a faster heating rate when the coffee beans are heated, and the lower coefficient of thermal expansion has the advantage of being suitable for long-time heating as described above.

The creation of the round coffee roaster drum 80 series is the first in the industry. The carbonized niobium in this creation is lighter than the conventional stainless steel product, so the weight of the round coffee roasting drum 80 can be reduced, and the weight of the whole roasting machine can be reduced.
