Description

Multifunctional Grain Stirring Device

Stir-frying of grains is an older recipe, mainly used for grains such as wheat, barley, beans and coffee beans. This roasting evaporates and expands the moisture in the grain, making it easy to grind, and the roasting object is deformed by heat. Coffee beans have been the fastest growing market in recent years. This is because not only did the instant coffee market which used Robusta species grow significantly, but also the consumption of Arabica increased rapidly due to the spread of cafe culture all over the world. At this time, apart from the instant coffee used by roasting coffee beans of Robusta species and drying them, coffee using Arabica species is roasted and used without any special processing. Therefore, unlike other grains, there is a tendency that the roastery cafe where coffee beans are directly purchased and roasted in a coffee handling cafe increases according to the characteristics that the freshness of coffee beans has a decisive influence on the quality of coffee produced. Therefore, there has been a need for a roasting apparatus capable of roasting coffee beans in a small space in place of the large roasting apparatus used in existing coffee plants.

The prior art for solving this problem has been disclosed in Korea Patent Publication No. 10-2009-0055112. The coffee bean roasting device was a device for roasting coffee beans housed in a drum by bringing a flame directly into contact with a drum called a roasting chamber. At this time, a plurality of fire holes are formed in the drum, so that the flame can directly contact the coffee beans. This roasting method is called direct fire in the sense that the flame is in direct contact with the coffee beans. This direct method has the advantage of roasting by expressing the characteristics of the region well, but there is a difference in the degree of roasting of coffee beans that are not in contact with the coffee beans in direct contact with the flame, and the surface of the coffee beans can burn the surface uncontrolled This has the disadvantage of being tricky.

There is also a hot air method, which is a method of roasting only through hot air. Hot air method can be roasted coffee beans evenly because the drum or coffee beans are not in direct contact with the flame, but the characteristics of the mountain region is not well represented.

The method of improving the roasting method of the direct heating method and the hot air method is the semi-hot air method. This flame is in contact with the drum to supply heat, and also by supplying hot air to roast the coffee beans evenly by the roasting method, there is an advantage that it is easier to express the mountain characteristics than the roasting method of the hot air method.

However, since the direct heating method or the hot air method and the semi-hot air method each require a different type of drum and a heating means, one roasting device has a disadvantage that only one roasting method can be used. In addition, since the size of the drum can not be actively changed to match the coffee beans, a conventional roasting apparatus having a size larger than necessary to buy and use. Therefore, it was difficult to roast coffee beans to the amount used, and accordingly, the coffee beans had to be roasted more than necessary. In addition, there was a limit to using the same drum for roasting according to the characteristics of the coffee beans.

FIG.

A multifunctional grain roasting apparatus having such a structure will be described below with an embodiment used for roasting coffee beans.

The body 110 is preferably formed in a cylindrical shape to facilitate the roasting of coffee beans. This is when the edge is formed, there is a disadvantage that even heat transfer in the interior of the body 110 is difficult because heat is not transferred to some corners in the heat circulation inside the body 110. Therefore, it is preferable that the body 110 is formed in a cylindrical shape to facilitate heat transfer therein.

The drum 121 formed in the drum 120 is also preferably formed in a cylindrical shape. The drum 121 is a portion in which a roasting operation, such as coffee beans, is input and roasted. Therefore, in order to evenly heat by uniformly supplying heat to the entire object of the roasting operation, the supply of heat to the drum 121 should be uniform. However, when formed in the shape of a polygon with a corner, a portion where heat is concentrated and a portion where heat cannot be transferred properly may occur. Therefore, it is preferable to form a cylindrical shape which can make the roasting work uniform. The cylindrical drum 121 is rotated through the drum rotating unit 130. Through this rotation, the roasting operation can be performed in a state in which the roasting object, such as coffee beans inside the drum 121, is not in a stagnant state, but can be roasted more uniformly.

At this time, the drum 121 is detachably coupled with the drum constraining means 122. Therefore, the drum 121 is preferably configured to be discharged to the outside using the drum outlet 113 formed in the body. In addition, the drum binding means 122 is formed of a plurality of frames. Therefore, it does not affect the heating method of the heating unit 140 has the advantage.

That is, the drum 121 is formed to surround it, but has a structure in which the flame of the heating unit 140 may directly contact.

In addition, the drum 121 may be provided with a temperature measuring device 124. This measures the internal temperature of the drum 121 during the roasting operation and transmits the information to the controller 150 to provide information necessary for the roasting operation.

In addition, as illustrated in FIG. 4, the drum unit 120 may include a flame prevention means 122 formed to be movable. The flame prevention means 122 is formed to be movable between the drum unit 120 and the heating unit 140 to block the flame generated from the heating unit 140 to the drum 121. do. This configuration is an essential configuration when changing the roasting method according to the object of the roasting work, such as hot air-style roasting work to cut the direct supply when the heat must be indirectly supplied to the hot air-style roasting work is possible.

In addition, the drum 121 may be formed of metal or ceramic. This is because when the drum 121 is formed to be detachable, using the roasting method that is optimized for the object of the roasting operation, the roasting operation is selectively performed using the drum 121 that is made of an efficient material for the roasting method. It has the advantage of being more efficient. In particular, in the roasting of the coffee beans, each coffee bean has the advantage of being able to produce a higher quality roasted coffee by using a material suitable for a separate roasting temperature and method for utilizing the flavor.

In addition, the drum 121 may be formed in a shape having a plurality of hollows. As shown in Figure 3 to 4, in the case of the hot air or semi-hot air of the method of roasting operation to avoid direct contact with the flame and to form a hollow on one side of the drum 121 to supply heat to the drum ( 121) is formed in a form in which the flame and the roasting object are not in direct contact. However, as shown in FIG. 2, in the case of the direct type, the drum 121 is formed in the form of a plurality of hollows in a manner in which the object of the roasting operation is in direct contact with the flame so that the flame is in direct contact with the object of the roasting operation. It should be formed to be possible. Therefore, the drum 121 may be used for roasting by selectively using a general cylindrical form or a cylindrical form having a plurality of hollows according to the roasting method.

3 to 5, the heating unit 140 may include a heating unit 141, a hot air supply unit 142, and an exhaust port 143. At this time, the heating means may be composed of a main burner (141a) and an auxiliary burner (141b). This can supply a sufficient amount of heat using only the main burner (141a) when using a direct roasting method. However, when the semi-hot air and hot air roasting methods are used, the heat deficiency generated because the thermal power of the main burner 141a cannot be directly supplied to the drum 121 can be solved through the auxiliary burner 141b. Therefore, the size of the main burner 141a can be reduced, which has the advantage of miniaturization, and when the auxiliary burner 141b is not required, the main burner 141a can be turned off regardless of whether the main burner 141a is operated. Has an advantage. Therefore, it minimizes the space occupied by the roasting device, thereby reducing the restriction of the installation place, and has the advantage of maximizing the economic benefit of the user by minimizing the energy consumption.

In addition, as shown in FIG. 5, the heat generated from the heating means 141 may be supplied to the drum unit 120 using the hot air supply means 142. The hot air supply means 142 may be composed of a hot air supply passage 142a and a hot air supply device 142b. At this time, the hot air supply passage (142a) is in communication with the heating means 141 and the drum unit 120 serves as a passage that the heat generated in the heating means 141 is supplied to the drum unit 120. In addition, the hot air supply device (142b) is preferably composed of a blower. When the heat generated from the heating means 141 was supplied to the natural air supply through the hot air supply passage 142a, the heat efficiency in the transfer process was low, thus consuming more fuel. However, the hot air supply device 142b is configured as a blower to supply heat generated by the heating means 141 to the drum 120 to minimize heat consumed in the hot air supply passage 142a. The thermal efficiency can be improved. Therefore, it is possible to transfer sufficient heat by using a smaller amount of fuel than conventionally consumed fuel, which has economic advantages.

Therefore, since the drum 121 is replaceable through the configuration of the drum discharge port 113 and the drum binding means 122, using the drum 121 formed in the form having a plurality of hollows and the heating means ( Through the main burner (141a) of the 141 can be used in the direct roasting method of the form in which the roasting object directly in contact with the flame, the drum 121 and the hot air supply means 142 is formed in a cylindrical shape It is possible to use a semi-hot air roasting method. The flame prevention means 123 is used to block the flame of the heating means 141 and supply the heat using the hot air supply means 142 is also possible to use the hot air roasting method of one stir device By using three kinds of roasting method is possible.

In addition, the controller 150 checks the current state of the drum unit 120 using the temperature measured by the temperature measuring device 123 formed in the drum unit 120. In this case, the drum rotating unit 130 and the heating unit 140 may be controlled according to the type and the roasting method of the roasting object received through the input unit 151 which may be provided in the controller 150. have. This enables the automatic control of the roasting operation has the advantage that the operator can increase the ease of roasting operation.

In addition, the inlet 111 is preferably formed in a funnel shape in which the cross-sectional area is reduced from the upper end to the lower end on one side of the body 110. This is easy when the roasting object, such as coffee beans, is formed wide, the input is easy, that is, when the coffee beans are put at once, the funnel-type coffee beans are moved smoothly so that there is no falling coffee beans to the outside. The inner passage is made small so that the internal size can be minimized. The inlet 111 formed in such a shape has an advantage of having a minimized volume to reduce the overall size.

In addition, the outlet 112 is formed to be opened and closed on one side of the body (110). The outlet 112 serves to discharge the roasting object, such as coffee beans to the outside. At this time, the outlet 112 may be formed to further include an auxiliary outlet 112b therein. The auxiliary outlet (112b) is a configuration for solving the problem that the discharge is difficult because the position of the outlet 112 is not matched with the drum 121 when the size of the drum 121 is formed small; ) Has the advantage of reducing the size constraint.

In addition, the exhaust port 143 is provided on one side of the body 110 serves to discharge the smoke generated from the heating unit 140 or the smoke generated from the drum 120 to the outside. In this case, the exhaust port 143 may further include a dust collecting device. Through such a configuration, the exhaust port 143 has an advantage of minimizing the foreign matter included in the smoke discharged to the outside and minimizing the influence on the surrounding environment.

In addition, the outlet 112 may be formed including a roasted grain cooling means (114). Stir-fried grains that are stir-fry may require rapid cooling after the work. Therefore, the roasted grain cooling means 114 is preferably formed at the bottom of the outlet 112 or the outlet 112 in which the roasted grains discharged from the outlet 112 can be directly cooled. This has the advantage that the roasted grains can be quickly cooled through the roasted grain cooling means 114 to save the flavor and taste when roasting the roasted grains, especially the aroma and taste of coffee.

In addition, the multi-functional grain roasting apparatus of the present invention can be used as a hot air stove even when not roasting grains, the multi-functional grain roasting apparatus of the present invention for use as a hot air stove can be further replacement of the drum for hot air heating.

In order to serve as a hot air stove, the multi-functional grain roasting device is used as a hot air stove by installing an air filter on the hot air supply means 142 and replacing the roasting drum where the hot air exhaust passes through with a hot air stove drum through which the hot air passes.
