Description

SYSTEM AND METHOD FOR CONTROLLING COFFEE ROASTING BACKGROUND OF THE INVENTION [0001]

The present invention relates to a system for coffee roasting and, more particularly, to a system and method for controlling coffee roasting to achieve optimal roasting.

In order to be made into a coffee beverage by a green bean, it must undergo three processes: distribution (hereinafter referred to as roasting), grinding (grinding), and extraction (brewing). Among these, roasting is the key step in the creation of the unique flavor of coffee, the last step before cup service.

Roasting is a time temperature dependent process that expands tissue and causes chemical changes to extract flavor and aroma. After roasting, the unpleasant flavor of the beans is transformed into a dark brown bean, which is then reborn as coffee beans. Roasting process, and it is known that more than 600 different chemicals are produced in soybean.

There are two seeds in the coffee tree, Cherry, which is called Green Bean. There is no taste in the raw state, it is just a hard seed.

Roasting expands the tissue to the maximum by applying heat to the beans to harmonize the various components of the beans (moisture, fat, fiber, carbohydrate, caffeine, organic acid, tannin, etc.). In order to make coffee that can be consumed, it is important to grasp the characteristics of green beans such as harvest time, moisture content, density, seeds, processing methods of the green beans, and the efforts of skilled roasters are necessary.

Generally roasted at a temperature of 220 ~ 230 ℃ for about 30 minutes, it becomes a coffee bean with a composition capable of producing 700 ~ 850 kinds of flavor. There are two traditional methods of roasting: pan roasting, which is a traditional method, and drum roasting, which is most widely used, and hot air roasting, which is mainly used for making instant coffee. The most common commercial drum roasting process consists of the following four steps (eg, green onion - dry - primary crack - secondary crack).

As a first step, green bean seeding is the initial step of roasting, in which green beans are put into a heated drum. At this stage, the color of green beans gradually changes from bright green to yellowish green.

As a second step, the Drying Phase changes the green beans from yellow to yellow, and changes the flavor of the green beans to a delicately baked flavor. At this stage, 70 to 90% of moisture disappears while the green bean absorbs heat (endothermic reaction), and the temperature of the drum gradually increases. Make sure that the amount of heat and pressure supplied to the inside of the drum is uniform through the damper (damper) (the thermal power is usually not higher than 210 ° C, the damper is closed or opened 30-50%, and the drum rotation speed is maintained at about 40-50 times .

In the third step, the 1st crack is also called Cinamon Roasting stage, and the heat is applied to oxidize the carbohydrate of green beans. At this stage, the center cut of the green bean can be heard crackling. At this stage, the surface of the bean becomes more swollen, the color is brownish and the surface is smooth.

In the fourth step, the 2nd crack is called Full City Roasting, and it is the most important step in the roasting process where the unique fragrance of the bean diffuses. After the first crack, the oil component inside the bean comes up to the surface of the bean, and the bean gradually changes from brown to dark brown and the surface expands more than the first crack. At this stage, the beans are more sweet than the sour taste due to the caramelization caused by heating.

On the other hand, the types of roasting machines include a direct type drum roaster, a indirect hot air type (convection type) drum roaster, and a fluid bed coffee roaster.

It is known that in the 12th and 13th century Arabs roasted on the fire after putting the green beans in a bowl made of clay or stone. A cylindrical roaster appeared around 1650. By the 19th century, the most commonly used drum-type roasting machine appeared, but in the latter half of the 20th century, a hot-winded coffee The roster has been developed and commercialized, and this big frenzy roaster has become a very efficient coffee roaster that can be roasted in large quantities by large coffee makers who make instant coffee.

Since 1980, in the United States, customers are starting to see the business form that they can buy coffee and drink freshly roasted coffee at the shop. Therefore, coffee roasters for small coffee shops were developed, but most of them were made by reducing the size of conventional commercial drum roasters.

These machines were not suitable for individuals or small coffee shops because they could not roast a small amount of beans (1kg or less) at a time. They had the problem of discharging smoke, dust, and smell through the communication pipe. (Roaster) had to spend a lot of time and effort in the work of adjusting the color of the beans and the coloring of the beans.

Conventional monitoring and roasting profile management system (for example, GIESEN COFFEE ROASTER PROFILE SYSTEM), which is produced by GIESEN in the Netherlands, has been developed, but the standard price is 6 million ~ 10 million Yuan, The coffee roaster profile system installed on the roaster has a drawback that it is developed for large-scale factory coffee roasting as high-priced equipment of more than about 100 million, and is not suitable for an individual or a small-sized coffee shop.

It is another object of the present invention to provide a coffee roasting control system that manages stock and roasting schedules through a web server and manages the scrap of roasted coffee beans.

Additional features and advantages of the invention will be set forth in the description which follows, and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the present invention will be realized and attained by the structure particularly pointed out in the claims, as well as the following description and the annexed drawings.
