Description

Auto-Parching Equipment for grain}

The present invention relates to a grain automatic roasting apparatus for controlling the roasting time and temperature of various grains and increasing the thermal efficiency while reducing pollution.

As it is known, in order to fry grains, the grains are put in a prepared container and stirred in a state where they are heated by the heat of an oil burner or a gas burner, so that the grains are heated evenly to be roasted in order to flavor the food. will be. However, in the process of roasting grains, it is necessary to finely adjust the heating temperature, the time and the stirring speed, but in most cases, it is virtually impossible to keep these optimum conditions, so that they are partially burned or roasted, and the inner and outer layers of grain The state of roasting is different, so that it is not roasted in a desirable state, the flavor of food is often lowered.

As such, the process of roasting grains one by one must pay close attention, and it is difficult to secure manpower because work is avoided due to heat, strong smell and generation of fine dust during heating of grains.

In addition, when using such an oil burner or gas burner, there is a possibility that a fire may occur due to inadvertent handling of fuel or a worker may be burned. Therefore, provision of countermeasures is urgently required.

Therefore, in recent years, an electric roaster has been introduced, which uses electric heaters to fry grains by controlling time and fire power according to grains from time to time, and there is a "grain roaster" of Utility Model Publication No. 96-66. It is equipped with a certain volume of vacancy under the pot and inserts an electric heater, thereby making it easy to control the roasting state, and it is safer and hygienic than the previous oil or gas-based roaster. It is done.

However, the roasting temperature is different for each grain, and the rising slope of the roasting temperature must be different according to the roasting time, and the holding time of the temperature is different for each time period. In the "stir stir control device" design, although the gas burner is used, the stir time, speed, and temperature setting are completed, but the stirring speed during the stir process must be properly adjusted. There was a problem that the flavor can not be obtained, and furthermore, the stirring speed also had to be controlled at various speeds according to time slots, and there was a problem in solving the problem of maintaining proper flavor for each grain.

In consideration of these problems, the first object of the present invention is to set the total heating time according to the grain, and adjust the amount of power supplied to the heater by referring to the heating temperature and the stirring speed (hereinafter referred to as "stirring speed") for each time zone. It is to provide a grain roasting device to obtain an optimal roasting state by giving.

A second object of the present invention is to provide a grain roasting apparatus in which a series of functional controls related to operation control of a grain roasting apparatus can be remotely controlled by a remote controller.

The third object of the present invention is to provide a grain roasting apparatus which is highly durable, has good thermal efficiency, and is capable of properly transferring a required temperature to grains.

A fourth object of the present invention is to provide a grain roasting apparatus capable of safe treatment of dust and water vapor generated in a cooking pot and improvement of thermal efficiency.

The fifth object of the present invention is to provide a grain roasting apparatus for automatically taking out the roasted grains when the roasting of the grain is completed.

We propose a grain roasting device that is utilized by a microcontroller to control an electric heater.

It is possible to increase the efficiency of the harmful gas and to provide useful effects such as protecting the environment.

This invention is described in more detail with reference to the accompanying drawings as follows.

Figure 1 is a schematic diagram illustrating the appearance of the scrambler according to the present invention, showing the overall configuration shown by breaking a portion to show the inner pot plate, Figure 2 shows the control system, the main part of the present invention as a functional block One block diagram is shown.

As can be seen from the above, the present invention provides a memory for storing data input by the keypad 1 and the keypad 1 consisting of the function selection key and the numeric keys of the keypad 1, and the internal temperature of the grain roasting tank. At least one temperature sensing sensor 2 for outputting as an analog value, a sensor signal amplifying circuit 3 for amplifying and outputting the output signal thereof, and a heater 18 as a heating heat source of grain to generate heat at an appropriate temperature A heater for controlling the power by the switching element by supplying a signal for controlling the power supplied to the heater control circuit 17 and the stirring motor 21 for rotating the stirring impeller for stirring grains to the photocoupler A motor driving circuit 8 for heat discharge and a fan motor driving circuit 9 for controlling a power supply by receiving a signal from the microcontroller 10 by a photo coupler, and a photo transformer The remote signal amplifier circuit 5 for amplifying the signal received by the stub 4, the decoder 6 for decoding the signal of the remote signal amplifier circuit 5, and the selected grains are displayed and displayed. The display unit 16, which displays the stirring time and the setting time according to the set temperature, the heater 18 temperature, and the grain temperature, and displays the stirring speed and the stirring speed, and receives the signals from the memory and receives the data from the memory. The microcontroller 10 is configured to selectively read and generate an output with reference to the condition specified by the keypad 1, the keypad 11 for operation control, the encoder 12, and the power amplifier and modulator 13 And a remote controller 15 composed of a light emitting diode 14 and a voice synthesis circuit 19 and a speaker 20 for outputting the termination guide voice under the control of the microcontroller 10.

The present invention as described above first turn on the normal power switch so that power is supplied to each part of the circuit by a power supply circuit (not shown).

Accordingly, the micro-controller 10 is to initialize the internal register value all at once, for this purpose, it is possible to supply a reset signal when the initial power is applied.

Subsequently, the microcontroller 10 scans the operation of the keypad 1, and waits for input, and types of grains stored in the memory at the time of manufacture as initial values and primary and secondary target temperatures, 1 and 2 It is waiting for reading data such as difference heating time and final temperature from memory.

In this state, when the user presses the keypad (1) to modify the status display, the type of grain and the value inputted according to the specified order are used to select a plurality of types of grain, new first and second target temperatures, and first and second heating times. And the final target temperature is designated, and the microcontroller 10 stores the input value at a specified address of the memory while displaying the type of the currently designated grain on the display unit 16.

After the input process is completed, press the input completed function key to complete the input. When the temperature inside the fry tank reaches a certain temperature, the user puts the grain into the fry tank and presses the operation function key of the keypad (1). ) Senses the temperature of the inside of the roasting tank by the temperature sensor (2) and is currently in operation, so that 100% power current flows through the heater 18, thereby rapidly increasing the internal temperature of the roasting tank.

In this way, the microcontroller 10 continues to check the temperature until the first target temperature is reached, and also the heater 18 so that the temperature detected by the temperature sensor 2 embedded in the pot plate 22 is maintained at the reference temperature. When the current flows to the primary target temperature is reached, the microcontroller 10 applies a signal to the stirring motor driving circuit 8 to change the rotational speed ratio of the stirring motor 21 (eg, high speed). It starts to stir grains at high speed by rotating them from 3 seconds slow 30 seconds mode to high speed 3 seconds slow 10 seconds mode. In this way, by increasing the ratio of the high speed of the rate of stirring the grain, the grain is cooked evenly even at a high temperature without burning or pressing on the cooking plate 22, the temperature of the grain gradually rises and this temperature change is a temperature sensor Is detected by (2). However, even at this time, the microcontroller 10 continuously controls the current of the heater 18 so that the temperature sensed by the temperature sensor 2 embedded in the stir bath maintains a constant temperature, which is the temperature of the stir bath and the grain. This is because the temperature is different, and the temperature of the roasting tank is kept at a slightly higher temperature than the required temperature of the grain, so that the roasting of the grain is satisfactory.

In this process, when the first heating time elapses, when the secondary temperature is set as necessary, the microcontroller 10 detects a signal of the temperature sensor 2 and contrasts the secondary temperature with the present sensing temperature. As a result, when the present temperature is lower than the secondary target temperature, the secondary target temperature is continuously reached by heating and stirring in the same pattern as described above.

However, the secondary target temperature may be omitted depending on the type of grain to be roasted. In the case of grains requiring a secondary target temperature (which is determined by the controller), as described above, when the secondary target temperature is reached, the microcontroller 10 By changing the stirring mode by a) and to control the heating power of the heater 18 it is possible to achieve the object. In this way, when the time elapses, the secondary heating time is terminated. At this time, the microcontroller 10 immediately compares the final temperature with the output value of the current temperature sensor 2 so that the microcontroller 10 continuously checks the internal temperature. When the temperature reaches the final temperature, the roasting is completed, and the fan motor driving circuit 9 is operated so that the fan motor discharges excessive heat to the outside.

In this state, the microcontroller 10 operates the voice synthesis circuit 19 to output the contents indicating that the roasting is completed to the speaker 20.

Therefore, the user hears this sound and operates the keypad 11 of the remote controller 15, which is carried, which is encoded by the encoder 12 and modulated by a predetermined signal by the power amplification and modulation unit 13, and the light emitting diode ( Infrared 14 is fired. Therefore, this infrared signal is incident on the phototransistor 4 and selectively amplified by the remote signal amplification circuit 5 and then decoded by the decoder 6 and applied to the microcontroller 10 as a completion or stop signal, and then the microcontroller ( 10) recognizes this and completes a series of roasting operations.

In this series of control processes, the microcontroller 10 uses a proportional integral derivative control scheme to control the outputs applied to the heater 18 and the stirring motor 21 by the output of the temperature sensor 2. It is preferable to adopt.

In addition, in the embodiment according to the present invention, but the communication between the remote controller 15 and the micro-controller 10 is made in the infrared, the advantage that can be operated in a place where the roasting device is not visible by using radio waves other than infrared In this way, the operation can be controlled after the completion of the roasting by using the remote controller 15, so that the user can return to work after the other work and collect the roasted grains to proceed to the next process.

4 is a cross-sectional view showing the internal device of the roasting apparatus, which is the main part of the present disclosure, and FIG. 5 is a detailed cross-sectional view for extracting only the cooking plate which is a part of FIG.

In another configuration of the present invention, the bottom of the cooker plate is a certain thickness of the iron, and the tube is embedded in the heating wire is enclosed therein, so that the heater and the cooker plate are made integrally, which excretes the tube with the heating wire in the guff house It is produced by pouring casting to the outside and solidifying it.The heating wire is sealed with the outside to increase the durability by preventing oxidation, and the cast cooker has enough volume because it is a bucket, so it has good heat capacity and thermal conductivity. Since there is a grain above, the operating temperature is transferred to the grain as it is, so that the thermal efficiency is high and the temperature control is perfect.

In addition, in another configuration of the present invention, the exhaust, such as dust and steam discharged from the cooker plate 22 is introduced into the water collecting tank 27 at the bottom of the main body through the duct 23, the fan motor (9 ') can be pressurized Therefore, the outflow of the exhaust gas is easy, and the outflowing exhaust gas collides with the funnel-shaped collecting plate 24 on the top of the sump 27 so that dust and water vapor fall, and only the filtered exhaust is discharged to the exhaust port 25. In addition, since the water in the sump 27 can be periodically exchanged through the outlet 26, purification of the exhaust gas can be performed to further reduce pollution, and if necessary, an air filter or a discharge fan is provided on the exhaust port 25 side. It is also possible to improve the purification of the gas and to improve the discharge power.

In addition, in another configuration of the present invention, in the well-known opening and closing structure installed in the roasting apparatus, the opening and closing motor 30 of the D / C motor is arranged in a straight line on the opposite side of the handle of the main shaft 29 on which the opening and closing handle is mounted. Since the roasting of the grain is completed and the grain is taken out, the opening / closing opening 28 can be arbitrarily opened and closed by operating the remote control unit 15 even at a long distance when the grain is taken out. Can be. At this time, the opening and closing structure is not particularly limited, but may be any opening and closing structure, but for example, in the structure such as the "measured grain roasting device" of Utility Model Publication No. 97-126 filed by the principal shaft {29; In the above invention, a structure in which the motor 30 is coupled or directly connected to one end of the discharge shaft 71 may be adopted. In order to allow opening and closing of the shaft, the open motor 30 may be configured as D. It is more preferable if it is a C motor. Of course, a device other than the above, for example, in the case of a blowout structure for opening and closing the cover of the opening up and down can be applied by using a linear motor instead of the D-C motor, even if such a structure is beyond the technical scope of the present invention It is not.

In this way, the present invention has the advantage that the temperature control and the stirring speed control are made in the most ideal state during the entire process of roasting the input grains, so that the flavor of the roasted grains is excellent. It is carried out automatically and can greatly reduce labor costs, it is very convenient to use, and the use environment can be improved.
