Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic roasting device suitable for use in roasting various beans, rice cakes, etc. (hereinafter simply referred to as various materials).

[Conventional technology]

Conventional roasting machines for roasting various materials are equipped with an operating frame that is horizontally rotated by a motor inside a roasting furnace that uses a gas burner as a heat source, and a roasting basket containing the various materials mentioned above is installed in this operating frame. By inserting the burner and rotating it horizontally, the flame of the gas burner roasts the ingredients in the roasting basket.
Pull out the roasting basket from the roasting furnace to discharge the ingredients,
It was kept cooled with outside air for the required time.

Problem to be solved by invention C] However, at the end of the above-mentioned roasting process or during the cooling process, the roasting basket heated to a high temperature in the roasting furnace must be manually pulled out of the furnace. It is dangerous and there are many accidents such as burns.
In addition, during the cooling process where the roasting basket is cooled at natural temperature, it is necessary to insert the pulled out roasting basket into the roasting furnace again after 20 to 30 seconds, and if this process of pulling out and inserting is repeated multiple times. Because of this, there is a problem that the work becomes very complicated.

In addition, an operator (
Unfortunately, it was not possible to easily save labor, as it was necessary for a worker to accompany the roaster at all times.

In addition, in the case of conventional roasting machines that use gas burners as the heat source for roasting, the flame temperature reaches over 1000 degrees Celsius, which causes problems such as being extremely hot and deteriorating the working environment. When roasting beans with different types of skins, the skins that fall through the mesh of the roasting basket may be burned by the flame of the gas burner, producing a large amount of smoke, further deteriorating the working environment. There was also.

Therefore, the technical problem of the present invention is to automate all of the various roasting operations such as loading and unloading the roasting basket into and out of the roasting furnace, and taking out the roasted materials stored in the roasting basket. 6 [Means for solving the problem] The measures taken in the present invention to solve the above technical problem are as follows. It is.

In a roasting machine configured to roast the material placed in a roasting basket by horizontally rotating the roasting basket inside the roasting furnace using a motor, (1) the above-mentioned roasting furnace; be configured to be freely movable forward and backward relative to the roasting basket by a moving motor.

(2) Far-infrared panel burners must be installed at the top and bottom of the roasting furnace.

(3) The entire roasting basket is configured to be able to stand up and rotate diagonally using a cylinder so that the discharge port faces downward.

(4) The time during which the roasting basket is in and out of the roasting furnace, as well as the timing for raising and rotating the roasting basket, can be freely set using timers.

[Effect]

The above means works as follows.

■The elements mentioned in (1) above can completely automate the work of loading and unloading the roasting basket into and out of the roasting furnace by controlling the rotation of the moving motor, which saves the labor of loading and unloading the roasting basket, and To improve work safety by eliminating accidents such as burns.

■The elements mentioned in (2) above are used as a heat source for roasting.
Since we use a far-infrared panel burner that can roast at around 0°C (regular gas burners are around 1000°C), there are problems with raising the surrounding temperature and burning skins etc. that have fallen through the mesh of the roasting basket. By solving this problem, it is possible to significantly improve the working environment.

■The element mentioned in (3) above is that when taking out the roasted ingredients from the roasting basket, if the roasting basket is raised and rotated with a cylinder,
The material can be automatically discharged from the discharge port, thus saving the labor of discharging the material, and at the same time,
It is possible to eliminate burn accidents that occur during discharge and improve work safety.

■The factors mentioned in (4) above include the roasting process time in which the roasting basket is placed inside the roasting furnace, the cooling process time in which the roasting basket is rotated outside the roasting furnace, and furthermore.

The timing of raising and rotating the roasting basket with a cylinder and taking out the roasted material from the discharge port can be automatically controlled according to the time set by the timer, eliminating the need for operator operation and roasting. Enables labor saving (full automation) of work.

As described above, the above-mentioned technical problem can be solved by the above-mentioned means, and the problems of the conventional technology can be solved.
