Description

Direct Fire Cold Flow Roasting Device of Bean Roaster

This model is to provide a bean roaster, especially a technical feature that can use the combustion source and the cold flow source to spray from the same side, thereby generating heat and cold impact on the coffee beans, and generating convection in the boiler body, so that the inside of the coffee beans The direct-fire cold-flow roasting device of the bean roaster is easier to cook quickly, without damage to the surface, and retains the flavor of direct-fire roasting.

By the way, the raw material of coffee is coffee beans. After collection, they must be roasted, ground into powder and other procedures before they can be brewed into delicious coffee. Especially the roasting procedure is related to the aroma of coffee. It is very particular about this point. For example, the temperature setting is divided into low-temperature baking, medium-temperature baking, and high-temperature baking.

The most primitive method of roasting coffee beans is to put the coffee beans in a pot, heat the bottom of the pot with fire, and then stir them manually to make the coffee beans evenly roasted. However, in the face of a large amount of coffee beans, manual turning Stirring is really laborious, and it is difficult to fry the coffee beans evenly.

Therefore, the later coffee bean roasting method is to put coffee beans into the boiler body and heat it with fire at the bottom of the boiler body. After the boiler body rotates, it can automatically stir the coffee beans. This method can save money. Both manpower and baking uniformity are more advanced than the original baking method. However, it is difficult to control the temperature of the fire directly at the bottom of the boiler body, and the temperature difference between the surface of the drum and the center of the drum is quite large. Even if it is stirred through the boiler body, It is still impossible to achieve a truly uniform maturity of coffee beans, and because of a fixed frequency of fire, when the temperature of the fire is greater than the conductivity of the coffee beans, the coffee beans will resist and reduce the effect of internal conduction, resulting in the inside of the coffee beans. Aged, but the surface has been damaged and charred.

In addition, as shown in the Republic of China Patent No. M570673, although this type of roaster introduces cold air into the boiler body, the cold air enters from the side of the boiler body. Into the boiler body, the disturbance effect on the inside of the boiler body will be poor , and the main purpose of introducing cold air in this patent is to reduce the temperature in the boiler body, which still cannot solve the problems of internal aging of coffee beans and damage to the outer skin.

Therefore, how to solve the above-mentioned conventional problems and deficiencies is the direction that the creators of the new model and related manufacturers engaged in this industry want to study and improve urgently.

Therefore, in view of the above shortcomings, the applicant of this model has collected relevant information, evaluated and considered in many ways, and based on years of experience accumulated in this industry, through continuous trial and modification, he designed this kind of available combustion source and The technical feature that the cold flow source is ejected from the same side, and then generate heat and cold impact on the coffee beans, and generate convection in the boiler body, so that the inside of the coffee beans can be cooked more quickly without damage to the surface, and the direct fire roasting can be maintained The patentee of the new type of direct fire and cold flow roasting device of the flavored bean roaster.

The main purpose of this new model is to set the outlet of the direct fire source and the outlet of the cold flow source on the same side, so that the technical characteristics of the combustion source and the cold flow source are ejected from the same side, so that the combustion source and the cold flow source enter the boiler body through the perforation at the same time , so that hot and cold convection and turbulence are generated in the boiler body, and at the same time achieve alternating hot and cold conduction heat, which effectively reduces the coke smell caused by excessive roasting, and the surface of the coffee beans is not easily damaged.

The structure that can achieve the above main purpose includes a boiler body for storing coffee beans. There are several perforations on the boiler body, and a combustion gas passage is provided under the boiler body, and several holes are arranged between the combustion gas passage and the boiler body. A straight fire source outlet connected to the combustion gas channel, in addition, a cold air gas channel is provided on one side of the combustion gas channel, and the cold air gas channel communicates with at least one cold flow source outlet, and the cold flow source outlet is arranged on the same side of the combustion gas channel. On the same side of the direct fire source outlet, so that when the combustion gas channel supplies the combustion source to be ejected from the direct fire source outlet, and the cold air gas channel supplies the cold flow source to be ejected from the cold flow source outlet, they will be ejected in the same direction , and passed through the perforation to the coffee beans in the boiler body, and the boiler body rotates at the same time. In this way, the combustion source and the cold flow source are ejected at the same time to generate alternating cold and hot conduction heat, achieving the above-mentioned advantages.

With the above-mentioned technology, it can solve the problem that the conventional bean roaster cannot make the coffee beans reach a truly uniform maturity, and the surface of the coffee beans is often damaged. The problem of epidermis damage is broken through, so as to achieve the practical progress of the new model as the above-mentioned advantages.

In order to achieve the above-mentioned purpose and effect, the technical means and the structure adopted by the present invention are hereby illustrated in detail with respect to the preferred embodiments of the present invention. Its features and functions are as follows, so as to fully understand.

Please refer to the first figure to the fifth figure, which are the perspective view to the action diagram of the direct fire source outlet and the cold flow source outlet of the preferred embodiment of the new model. It can be clearly seen from the figure that the new model includes:

A boiler body 1 for accommodating coffee beans C, the boiler body 1 has several perforations 11;

A combustion gas channel 2 provided under the boiler body 1;

Several direct fire source outlets 21 are arranged between the combustion gas channel 2 and the boiler body 1 and communicate with the combustion gas channel 2;

A cold wind gas channel 3 arranged on one side of the combustion gas channel 2; and

At least one cold flow source outlet 31 communicated with the cold air gas channel 3 and arranged on the same side as the direct fire source outlet 21, so that the combustion source A passing through the direct fire source outlet 21 and the cold flow source outlet The cold flow source B of 31 can advance upwards from the same direction, and pass through each of the perforations 11 to roast the coffee beans C.

Wherein, the cold flow source outlet 31 of this embodiment is taken as an example.

Wherein, the boiler body 1 is connected with an exhaust channel 12 .

Wherein, the direct fire cold flow roasting device is set on a bean roaster D.

Wherein, the combustion source A takes gas as an example in this embodiment.

Wherein, the cold flow source B takes external natural wind as an example in this embodiment.

When roasting coffee beans C, the coffee beans C can be placed in the boiler body 1 first, and then the combustion source A and the cold flow source B are provided. The combustion source A will pass through the combustion gas channel 2 and then reach the direct fire source outlet 21 , and then move it to the boiler body 1 at the top. Similarly, when the bean roaster D is in operation, the external natural wind (later called the cold flow source B) will be sucked into the bean roaster D, and the cold flow source B will pass through The cold air gas channel 3 reaches the cold flow source outlet 31, and then it travels to the boiler body 1 above. At this time, the combustion source A and the cold flow source B will pass through the perforation 11 at the same time to treat the coffee beans C in the boiler body 1. The baking operation is carried out, and at the same time, the exhaust channel 12 discharges the gas in the boiler body 1 .

It is worth mentioning that when the combustion source A and the cold flow source B spray upward toward the boiler body 1, because there is the travel zone 4 between them, when the combustion source A touches the boiler body 1, it will be affected by the cold flow source The relationship of B moving together, its temperature will be slightly lower than the initial temperature, as the temperature coming out from the direct fire source outlet 21 is 1,000 degrees, and it will form 930 degrees when it reaches the boiler body 1. Similarly, the cold flow source B is subjected to the relationship of the combustion source A co-progressing, and its temperature will be slightly higher than the initial temperature. For example, the temperature coming out of the outlet 31 of the cold flow source is 30 degrees, and when it reaches the boiler body 1, it will form 100 degrees. In this way, the cold and heat are alternated at the same time A vortex-like airflow will be generated, which is called turbulence, and then has a fluctuating heat conduction, making the temperature change frequency, so that the capillary pores of the coffee beans C can act like respiration, making heat energy easier Conducted into the coffee bean C, forming the inside of the coffee bean C to ripen faster, but the surface will not have the problem of excessive burnt damage.

Among them, the so-called volatility or frequency refers to the impact of one cold and one heat on coffee beans C, rather than only thermal energy. The heat transfer coefficient makes the inside of the coffee bean C mature faster and easier, and at the same time does not cause excessive coking of the skin of the coffee bean C. In addition, since the direct fire type combustion source A is used in this case, the combustion source A can directly contact the coffee beans C through the perforation 11, so that the coffee beans C can produce the special aroma of the flame tattoo.
