Description

Teaching coffee bean transparent furnace roasting machine

The invention relates to a teaching roasting machine with a transparent furnace body for coffee beans, in particular to a teaching roasting machine including a transparent drum and a ceramic heater.

According to the rules of thumb of human dietary civilization, the principle of cooking food is nothing more than to make it easy to digest, absorb and create a delicious taste. The same is true for coffee roasting. Improper baking will either make it impossible for people to absorb, or destroy all the delicious food. Proper baking will not only not cause physical discomfort, but also present the nutrients in a charming flavor. When the coffee beans are roasted to a certain temperature, the sugar begins to undergo a caramelization reaction, and the amino acids and carbohydrates also begin the Menard reaction, producing a large amount of carbon dioxide and water vapor. When the cell wall cannot withstand the large amount of pressure, the carbon dioxide breaks out. The crackling sound is the beginning of the first phase. To put it simply, the entire process in which various aromatic substances are gathered in the coffee beans and released through pressure is referred to as first crack in the industry. The second stage is the same as the first stage. The cell wall cannot withstand the pressure and breaks, and the wood fibers in the cells begin to volatilize. Some people may not roast beans to this stage because each bean has a different optimal roasting degree and personal preference. The darker the roasting degree, the deeper the caramelization will be, and the easier it is to produce a burnt and bitter taste. So how to Controlling the heating temperature and judging the color change of the beans depends on the personal experience of the roaster. However, the traditional roasting drum is made of metal and is an opaque container. The heat source is transmitted to the inside of the metal drum through the heater at the bottom. , providing the heat source needed for roasting beans. Therefore, an inexperienced person in the bean roasting process cannot tell whether the beans have been roasted to the desired degree. To this end, some manufacturers have developed roasters with windows, such as Taiwan New Patent No. 569669-1 A "structural improvement of the roasting machine. The content mentions that the front cover is equipped with a transparent front window. In addition, Taiwan's new patent No. M519779 is a portable coffee bean roasting device. The content mentions that there is a peep-through drum on the flip-up cover. There is a transparent window showing the status of the roasted beans inside, and Taiwan’s new patent No. M624790, a coffee bean roasting machine, also mentions that the cover is equipped with a viewing window. From the above patent, it can be seen that although the roasting machines currently developed by the industry have a viewing window You can watch the color changes of the beans in the drum, but the windows are partial and very small. You can only see a small part, and you cannot fully see the changes in most beans. There is room for improvement. The reason is that in view of this, the creator has many years of relevant teaching and practical production experience, and has further researched and improved the existing technical means to provide a teaching coffee bean transparent furnace roasting machine in order to achieve the purpose of better practical value. By.

The purpose of this new model is to provide a transparent oven roasting machine for teaching coffee beans. As the coffee beans continue to be heated, the color of the coffee beans will change from gray-green to golden yellow, then light brown, russet with a slight amount of oil, and then A large amount of oil will appear oily and dark brown. If the roasting continues, the oil on the surface of the coffee beans will dry out and appear black, and a large amount of smoke will be emitted, mixed with a burnt smell. This is a warning that the coffee beans are close to the ignition point. This new type of coffee bean can clearly see the complete color change of the coffee beans through the full view of the transparent drum, avoiding uneven color of the roasted beans.

Another purpose of this new model is to utilize the advantages of fast heat transfer and uniform temperature of ceramic heaters or infrared heaters to quickly provide the heat source required for roasting beans, which is safe and efficient, and the temperature is easy to control.

The new model is a transparent furnace roasting machine for teaching coffee beans. The roasting machine includes: a base with a bracket on both sides of the base, and a transparent drum pivoted on the bracket and having a receiving space. , and a power motor arranged on one side of the base and driving the drum to rotate; a heater, the The heater is set on the base and provides the heat source required for the transparent drum to roast beans. Through the transparent drum during the roasting process, the color changes of the beans can be completely visually observed to achieve the effect of real-time teaching.

In order to have a more complete disclosure of the technical content to achieve the purpose of this new model, it is described in detail below, and please refer to the disclosed diagrams and diagram numbers: First, please refer to the tutorial shown in the first diagram. A transparent furnace roasting machine for coffee beans, which includes: a base 1 with a bracket 2 on both sides of the base 1, and a transparent drum 3 pivoted on the bracket 2 and having an accommodation space. The drum 3 can accommodate coffee beans, and a power motor 4 is provided on one side of the base 1 and drives the transparent drum 3 to rotate. The power motor 4 is a servo motor. In addition, the power motor 4 is a servo motor. There is a heater 5 on the base 1. The heater 5 is a ceramic heater or an infrared heater. The heater 5 provides the heat source required by the transparent drum 3 when roasting beans. During the roasting process, the transparent drum 3 can It can completely visually observe the color changes of beans to achieve the effect of real-time teaching.

Please continue to refer to the first to third figures. In this embodiment, the heater 5 is a ceramic heater. The ceramic heating element is made by sintering the electric heating element and the ceramic at high temperature and fixing them together. The heating element is an efficient heating tool with uniform heat distribution. It is a metal alloy with excellent thermal conductivity, which can ensure uniform temperature of the hot surface. It has the characteristics of energy saving, safety and long life. In addition, the heater 5 can be an infrared heater. , also has the characteristics of rapid heating, energy saving and safety. Next, we will use the roasting process to match the operation method of this invention. First, the transparent drum 3 will be preheated with the heater 5, and the temperature will be set to the temperature for starting roasting. Since the moisture content of green coffee beans is usually 10-12%, the moisture content It is a heat-conducting medium and starts to increase the temperature of the heater 5. At the same time, the power motor 4 drives the transparent roller 3 to rotate slowly. As the temperature increases, the free water of the beans slowly evaporates. At this time, the raw beans can be seen directly from the transparent roller 3. The green turns from white to yellowish brown, and smells a bit like the aroma of toast. Next is the so-called Menard reaction and caramelization. Menard reaction refers to the reducing sugars and proteins/amino acids in food. A series of reactions that occur during heating produce brown-black macromolecular substances, also known as flavor compounds. When the coffee beans turn a darker brown and the temperature of Heater 5 climbs to close to 195 degrees, be aware of the impending popping sound. First crack is the reaction that occurs when the carbon dioxide and water in the green beans expand due to heating and expand. It is also a key point that affects the flavor. When roasted to the selected roasting degree or temperature, the beans can be cooled and completed. The entire baking and production teaching process. With this new design, the roaster can clearly see the complete color changes of the coffee beans through the transparent drum 3, and understand which stage the beans are currently in through the color changes, thereby achieving effective teaching purposes.
