Abstract
Description
Technical Field
[0001] The utility model relates to a roasting machine with good coffee bean roasting effect. Background Art
[0002] A coffee bean roasting machine is a device for roasting coffee beans. The coffee bean roasting machine mainly heats and roasts coffee beans through a heating element. There are various types of coffee bean roasting machines on the market, but there are still certain structural drawbacks. For example, the position of the heating element is not properly set. When the coffee beans are roasted while rotating in the drum, there are problems of low thermal efficiency and uneven heating, resulting in low roasting thermal efficiency and prolonged roasting time.
[0003] Therefore, it is necessary to make further improvements to it. Summary of the Utility Model
[0004] The purpose of the utility model is to overcome the above problems and provide a roasting machine with good coffee bean roasting effect, which has the advantages of high thermal efficiency and uniform coffee bean roasting.
[0005] To achieve the above purpose, the utility model provides a roasting machine with good coffee bean roasting effect, including a roasting barrel arranged inside the machine body. A stirring paddle for stirring is arranged inside the roasting barrel. At least one heating device is arranged on the outer wall of the roasting barrel. The heating device includes an outer cover body and a heating element. The heating element is arranged inside the outer cover body. The outer cover body is fixed on the outer wall of the roasting barrel. An opening is formed on the wall of the roasting barrel corresponding to the inside of the outer cover body.
[0006] In one or more embodiments, a bean separating net is arranged on the opening. The bean separating net can prevent coffee beans from entering the inside of the outer cover body. The bean separating net is fixed on the roasting barrel.
[0007] In one or more embodiments, the number of the heating devices is multiple, and the heating element is a heating tube.
[0008] In one or more embodiments, heat insulation cotton is arranged on the outer side of the roasting barrel and the outer side of the outer cover body.
[0009] In one or more embodiments, the outer cover body extends along the axial direction of the roasting barrel, and the outer cover body is fixed on the roasting barrel by welding or screws.
[0010] In one or more embodiments, the outer cover body is arranged at the upper middle position of the roasting barrel.
[0011] The effects of the present utility model compared with the background technology are as follows: This coffee bean roaster is different from the roasters on the market. It sets the heating element inside the roasting barrel. When the heating element generates heat, it can directly radiate the heat to the inside of the roasting barrel, enabling the coffee beans to be better roasted and reducing the external loss of heat; it has an obvious effect on shortening the roasting time of the coffee beans. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a schematic diagram of the internal structure of the roasting barrel in the embodiment of the present utility model;
[0013] Figure 2 is Figure 1 a cross-sectional view of. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] In order to deepen the understanding of the present utility model, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings. The embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.
[0015] Please refer to the attached Figure 1-2 , this application provides a roaster with good roasting effect for coffee beans, including a roasting barrel 1 arranged inside the machine body. A stirring paddle 2 for stirring is arranged inside the roasting barrel. The stirring paddle stirs the coffee beans inside the roasting barrel to make the coffee beans heat more evenly during roasting. At least one heating device is arranged on the outer wall of the roasting barrel 1. The heating device includes an outer cover body 3 and a heating element 4. The heating element is arranged inside the outer cover body. The outer cover body 3 is fixed on the outer wall of the roasting barrel 1. An opening 5 is formed on the wall of the roasting barrel corresponding to the inside of the outer cover body. The heat generated by the working of the heating element is transmitted to the inside of the roasting barrel through the opening to roast and heat the coffee beans, which is equivalent to setting the heating element inside the roasting barrel. The advantage is that the heat of the heating element is directly radiated into the roasting barrel, reducing the external loss of heat, improving the thermal efficiency, and making the coffee beans heat more evenly.
[0016] A bean separating net 6 is arranged on the opening. The bean separating net can prevent coffee beans from entering the inside of the outer cover body. The bean separating net is fixed on the roasting barrel 1. During the stirring process of the stirring paddle, the coffee beans may be lifted to the height of the opening. Setting the bean separating net can prevent coffee beans from entering the inside of the outer cover body.
[0017] The number of the heating devices is multiple. The heating element 4 is a heating tube. The heating tube has a fast heating speed, a high power and temperature control.
[0018] In order to further reduce the heat loss, heat insulation cotton 7 is arranged on the outside of the roasting barrel 1 and the outside of the outer cover body 3.
[0019] The outer casing 3 extends along the axis direction of the baking barrel. The outer casing is fixed to the baking barrel 1 by welding or screws, so that the length of the outer casing tends to be consistent with the size of the baking barrel, the opening of the mouth can be made larger, the heating tube can more easily radiate heat into the baking barrel, and it is beneficial to the uniform heating of coffee beans.
[0020] The outer casing 3 is arranged at the upper middle position of the baking barrel, so as to avoid coffee beans hanging at the mouth position or on the bean separator net.
[0021] The above description is only the preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modification or change made by those of ordinary skill in the art according to the disclosure of the present invention shall be incorporated into the protection scope recorded in the claims.
