Far infrared bean baking bucket

This creation is about a bean roasting device, especially a far-infrared bean baking bucket that can improve the flavor and uniform heating effect.

According to coffee, coffee is a fairly common and popular drink. It is usually made from roasted and ground coffee beans. Among them, raw beans of different origins and quality have their own degree of ripening (ie shallow, In the middle and deep roasting state, the coffee beans can be made to have a unique aroma and flavor. Therefore, the baking effect of coffee beans is one of the main factors affecting the taste of coffee.

The existing bean roasting device, such as a coffee roaster (or a roasting machine), can be roughly classified into a direct fire type and a hot air flow type according to the heating method. The former means that the coffee beans in the drum are directly grilled by the fire. The heating efficiency is fast, but it is easy to cause the coffee beans to be black or the heat inside and outside is inconsistent due to over-baking. The hot air type is to boil the coffee beans by high-temperature hot air, and the heat conduction effect is relatively uniform, but it needs to heat a large amount of air, so it consumes a large amount of energy. .

Therefore, how to improve the above-mentioned lack of the conventional coffee roaster, that is, the technical difficulties that the applicant of the case wants to solve.

In view of the conventional coffee roaster, it is difficult to simultaneously meet the requirements of heating efficiency and heating uniformity, and does not have a structural design that can retain and enhance the aroma of coffee beans. The purpose is to develop a bean baking bucket which can improve the heating efficiency, increase the flavor after baking and improve the heating uniformity.

In order to achieve the above objective, the present invention provides a far-infrared bean baking bucket, comprising: a roller; a spiral stirring blade assembly, the spiral stirring blade assembly is fixed on the inner wall of the roller, and the spiral stirring piece assembly is provided Two spiral stirring sheets are disposed in opposite directions, and each of the spiral stirring sheets is fixed with a plurality of far-infrared ceramic sheets.

The drum has a cylindrical body, a first side wall at one end of the barrel body, and a second side wall at the other end of the barrel body. The first side wall side is provided with a hot air blowing port, the first The other side of the side wall is provided with a plurality of obliquely and radially diverging hot air outlets, each of which is in communication with the hot air supply port and the inside of the barrel.

Wherein, the far-infrared ceramic piece is combined with the spiral stirring piece in a screwing manner.

Wherein, each of the far-infrared ceramic sheets is fixed with a porous ceramic sheet.

Further, the upper surface of the porous ceramic sheet is formed with a plurality of parallel strip microstructures or a plurality of bump microstructures.

In this way, the present invention can realize the far-infrared baking function with a relatively simple structure, and the beans can be directly contacted with the far-infrared ceramic sheets to improve the heating efficiency, thereby shortening the baking time, and at the same time, the beans can be turned back and forth to improve the heating uniformity. Sex, which can greatly improve the practicality of this creation.

Referring to the first and second figures, the present invention provides a far-infrared bean baking bucket comprising: a drum 3 having a cylindrical shape, and the drum 3 having a cylindrical body 31. A first side wall 32 at one end of the barrel 31 and a second side wall 33 at the other end of the barrel 31. Generally, the drum 3 is disposed horizontally, the first side wall 32. A hot air vent 321 is provided on one side for inputting hot air for baking, and the other side of the first side wall 32 is provided with a plurality of obliquely and radially diverging hot air outlets 322, and each of the hot air outlets 322 is respectively The hot air blowing port 321 and the inside of the barrel 31 communicate with each other for feeding hot air into the inside of the barrel 31. In addition, the drum 3 is usually connected to a power unit (not shown) such as a motor for driving. The drum 3 is rotated to realize the function of tumbling the coffee beans, wherein the structure of the power unit and its specific connection with the drum 3 are common knowledge well known to those skilled in the art, and will not be further described herein. The first side wall 32 and the second side wall 33 can be A feed port 323 and a discharge port 331 are respectively provided for respectively inserting or taking out the beans to be baked and the beans after baking; 3; a spiral stirring piece assembly 4, the spiral stirring piece assembly 4 The spiral agitating blade assembly 4 is provided with two spiral agitating blades 41 arranged in opposite directions. In this embodiment, the "opposing arrangement" means Reverse winding, that is, when The same side wall of the body 31 is viewed in the direction of the first side wall 32. One of the spiral stirring piece assemblies 4 is wound in the clockwise direction inside the drum 3, and the other spiral stirring piece 41 is The counter-clockwise direction is disposed inside the drum 3, and further, each of the spiral stirring sheets 41 is fixed with a plurality of far-infrared ceramic sheets 5, for example, in a preferred embodiment, The far-infrared ceramic sheet 5 is combined with the spiral stirring piece 41 in a screw-solid manner. This is because the screw-solid is not subject to the problem that the high temperature may cause the release of the chemical component of the adhesive or the adhesiveness cannot be maintained. It has better practicality; the following explains the working principle and beneficial effects of this creation: It can be noted that for the convenience of understanding, this is an example of roasted coffee beans, but in fact, this creation can also be applied to baking other beans. Such as soy or soybean, and can have the same effect. Referring to the first and second figures, the first side wall 32 of the drum 3 is provided with a plurality of oblique and radially diverging hot air outlets 322, so that hot air can be formed inside the barrel 31.
