Description

Fryer {FRYER}

The present invention relates to a pressure pressurized fryer that frys various bloods such as meat or fish by applying pressure and heat, and more specifically, allows fast control at an appropriate temperature for frying. The temperature distribution is made evenly in the container, and the oil or residue (hereinafter referred to as "residue") generated after the frying treatment and remaining in the frying container can be classified and discharged to purify the frying oil and provide ease. It is about one fryer to make.

In the conventional fryer, since the temperature difference in the frying container is severe, the frying temperature cannot be kept constant for various kinds of fried foods, so that the fried foods are partially unripe or the taste is significantly decreased. For example, assuming that 5 chickens are fried, chicken is fried in a state where a proper temperature of 170 ° C. is maintained, and the chicken is fried in a frying container as fried chicken in a semi-frozen state (0 to 5 ° C.). If you put it, the frying temperature will drop rapidly, and about 20 ℃ will drop at the proper temperature. It takes a lot of time and electric capacity to raise the 20 ℃ again in this falling state, and in the past was not able to solve this quickly and comfortably, and caused a significant problem in maintaining the proper temperature, so that the chicken is unripe or tastes remarkably There was a problem falling.

In addition, by continuously using the residues (animal oil, debris, heavy metals, etc.) that are generated after frying and remaining in the fry container, the flavors of bloody products are reduced, as well as fatty cholesterol and heavy metals are contained. There is a problem that the consumer to be absorbed by the charge to the body is subjected to health harm.

On the other hand, there is also a fryer equipped with a filter means for filtering the remaining residue in the frying container after the frying process, but in order to maintain a clean frying oil in the frying container, the filter means must be frequently replaced to provide a user with a hassle. There was a problem that the cost is consumed separately.

The present invention was devised to solve the above problems, and its purpose is to allow the programming control by the microcomputer to quickly and accurately control the temperature in the frying vessel to the proper temperature required for the splatter, and the proper temperature. It is to provide a fryer to facilitate automatic maintenance and control of the machine and to easily check for abnormalities of the equipment.

The present invention is to arrange the electric heater and the temperature sensor in the frying container, but to promote structural efficiency to effectively control the heat transfer or exchange and temperature maintenance in the frying container.

The present invention aims to provide the ease of treatment of residues by classifying and discharging animal oil, residues, and heavy metals remaining in the frying container after the frying of fried foods using the difference in specific gravity.

At this time, the controller 123b is composed of a microcomputer for programming control of each component circuit and is connected to a memory of the EEPROM in which all data is stored / stored.

Referring to the operation relationship or action of the fryer according to the present invention made in such a configuration as follows.

First, the operation relationship according to the electronic circuit configuration will be described.

When power is input to the fryer, the power supply circuit 123a causes voltages AC 220V, DC 5V, and DC 6V to be applied to each component circuit. When the power is applied, the current temperature, the set temperature, the frying time, the number of frying and the quantity of the data stored in the display unit 122 on the control panel 120 are displayed and the standby state. At this time, the number / amount of fried is displayed as the initial value "1". In order to reduce or decrease the temperature in this standby state, operate the UP or DOWN button of the tempura selection / adjustment mode (121e) and press the SET button to be stored in the memory. The temperature can be controlled directly and the set temperature by the SET button is automatically released when the proper temperature of the blood is reached. In addition, to change the frying time, the time adjustment mode 121d may be adjusted.

When the START signal is applied through the operation mode 121a, the controller 123b detects the voltage change according to the manipulation, and the set frying time is discounted and is transmitted from the temperature sensing circuit 123e. The temperature data and the set temperature data are compared / analyzed by the controller 123b to control the output of the heater control circuit 123c on / off to adjust the voltage of the electric heater H so that the set temperature can be kept fast and stable. do. At this time, when the controller 123b detects a temperature rise through the temperature sensing circuit 123e, the heater control circuit 123c is turned off so that the heat supply of the electric heater H is made low, and when the temperature decrease is detected, the heater is controlled. The circuit 123c is turned ON to control the heat supply of the electric heater H to be high.

Here, looking at the temperature control process, for example, assuming that five chickens are fried, selecting the ⑤ button in the fried amount control mode 121e of the operation unit 121 sets the preset temperature (190 ° C) by this. The controller 123b controls the output of the heater control circuit 123c, and when the five chickens (semi-frozen state) are put in, about 20 ° C. is lowered within 5 seconds. The controller 123b has a temperature sensing circuit 123e. This is sensed through and if the 5 ℃ or more falls from this time by controlling the output of the heater control circuit 123c to automatically maintain the temperature of the fried oil to a proper temperature (170 ℃) suitable for frying chicken. At this time, the set temperature by the button ⑤ is automatically released when the optimum temperature is reached through the output control of the heater control circuit 123c through the temperature detection of the controller 123b, and the controller controls to maintain the proper temperature at all times. Therefore, the system is applied so that the proper temperature is always maintained even if the temperature is lowered by raising the temperature in advance before frying through the selection button of the frying water / quantity. It can be controlled and the set temperature to be recognized by one touch has the advantage of providing convenience.

In addition, when a voltage is applied to the heater H of the heater control circuit 123c, the heater check circuit 123g sends the current signal sensed through the current transformer CT for the instrument to the controller 123b and the controller 123b. ) Analyzes the current detection signal and checks whether the heater is disconnected, and when an error occurs, turns on the light emitting lamp (H / ERROR) and emits an alarm through the alarm means.

In addition, when the set frying time is completed, the controller 123b turns on the solenoid control circuit 123d to operate the solenoid SOL, and opens the solenoid valve 115 connected to the frying container 110 side in the frying container. Allow steam pressure to escape. At this time, the solenoid (SOL) is operated to completely lower the steam pressure in the frying vessel, the solenoid detection circuit 123f detects the current flow of the solenoid (SOL) to send the presence or absence of operation of the solenoid to the controller (123b) 123b) causes an alarm to be emitted through the alarm means in the case of a failure and turns on the light emitting lamp SOL / ERROR.

On the other hand, when the operation signal of the power saving function (ECONO) is applied in case of not using it for a while, the controller 123b reads the voltage change thereof to turn on the light emitting lamp (ECONO) and the heater (through the heater control circuit 123c). By lowering the current to H) to prevent unnecessary power waste.

In addition, the heater control circuit 123c and the solenoid control circuit 123d adopt a contactless alternating current method by applying a triac (TRIAC) to suppress the electrical noise at the time of output control of ON / OFF through the controller 123b. It works.

Next, the action between the components for the discharge of residues such as animal oil or debris will be described.

After pushing the first valve lever 161 to open the first opening / closing valve 151, when the residue submerged on the lower surface of the frying container 110 is introduced into the discharge pipe 150, the first valve lever 161 is pulled out to remove the residue. 1 Close the on-off valve 151. Residues introduced into the discharge pipe 150 sinks according to their specific gravity in the fractionation space 153 to form a fractionation layer. For example, cooking oil, animal oil, dregs and heavy metals form the fractionation layer. Due to the difference in specific gravity, the heavy metal forms the lowest layer, and the residue, animal oil and cooking oil form the upper layer sequentially.

When the division layer of the residue is formed in the classification space 153 of the discharge pipe 150, the second valve lever 162 is pushed to open the second opening / closing valve 152, and then the residue forming the classification layer is lowered. From the upper to the upper floor to the discharge pipe 170 disposed on the lower side of the discharge pipe 150 is separated and discharged for each floor by pulling the second valve lever 162 to close the second on-off valve 152.

As described above, according to the fryer according to the present invention, it is possible to control the heat transfer or exchange evenly according to the efficient structure arrangement design of the electric heater and the temperature sensor, while maintaining the programming control. Not only can it be automatically maintained, but it also enables accurate temperature control.

Even temperature distribution in the frying vessel and easy control thereof can be carried out, so that not only the proper temperature of the frying temperature can be kept constant at any time, but also the temperature variation in the frying vessel and the frying oil can be eliminated or minimized.

Thus, since the efficient execution and ease of temperature control in the frying container can be provided, evenly fried and cooked blood fries can be used, thereby providing usefulness that can prevent deterioration of taste due to partial unripe cooking.

In addition, since the remaining residues in the frying vessel are classified using the difference in specific gravity and then discharged, the purification of frying oil can be made more efficient, and the use of valves and levers makes it easy to separate the residues without any complicated refining process. It can be discharged and it is useful to reduce the cost of refining the fried oil.

In addition, it is possible to easily check whether there is an abnormality of the device, but the user can easily determine the failure site according to the failure, and can not only stably operate the device but also provide convenience for using the device.
