Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fryer,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fryer and its quality control apparatus and method, and more particularly, to a fryer and its quality control apparatus and method for cooking frying products using edible oil, oil, palm oil and the like.

Generally, the fryer is manufactured in various forms for household, business, or factory, and is a device for frying fried food or frying product by frying the food raw material through cooking oil, oil, and palm oil introduced into the fryer.

Recently, as eating habits have become westernized and simplified, modern people are exposed to many types of fast food, and the consumption of fat is also increasing. Since the spoiled oil is an important factor affecting the health of the people, the fryer using the frying oil or the oil is used for the oil management, the fryer maintenance and monitoring management in consideration of the optimized taste, flavor, texture, .

In particular, quality control of fryer oil has a major impact on the quality of fried products and the public health.

For example, when the temperature of the oil is not properly controlled in the fryer, even if the fried product is the same, the taste and texture are different, but a specific chemical substance may be produced or the production amount may vary.

For example, according to the studies of the prior art (Korean Food and Drug Journal, Vol. 41, No. 4, 2009.8, 471-475), the amount of acrylamide formation and sensory quality according to heating temperature and time of french fry were investigated have. Here, it has been found that the change in the heating temperature and the heating time has a great influence on the acrylamide production amount.

Generally, french fries are heated at 160-180 ° C for 2-5 minutes. The production of acrylamide is greatly influenced by heating temperature and time, so that acrylamide production in food can be reduced by controlling the temperature.

In addition, it is important to prepare a french fryer having excellent sensory properties while reducing the amount of acrylamide. Thus, heating for 2 minutes and 30 seconds at 165 ° C for the production of french fries reduces the production of acrylamide, Excellent french fries can be produced.

On the other hand, since the quality of the fried food prepared according to the number of times or times of frying of the oil to be used may be influenced by the fryer, it is preferable to use a fryer after the appropriate frying time or using an acid value measuring device It should comply with the acid value standards.

Here, the acid value refers to the number of mg of KOH (potassium hydroxide) required to neutralize the free fatty acid in 1 g of fat. In other words, as the acidity of the fat is increased, the free fatty acid content increases and the amount of other acidic substances increases, resulting in a lower pH. The value obtained by measuring the amount of the alkaline substance put in such a neutral state is the acid value.

The patent literature, which is the background of the invention, suggests a function of simply displaying and informing the replacement time of the frying oil.

This is for the convenience of the manufacturer. Consumers actually consuming edible oil products cooked or processed through the corresponding fryer actually use the acid value standard value of the edible oil product in accordance with the acid value standard value 3.0 for edible oil in the Korean Food Hygiene Act I can not tell if it is satisfactory.

Therefore, even if the manufacturer who manufactures, imports, processes, uses, cooks, and preserves uninhibited edible oil-preserved products recognizes the replacement time of the frying oil (hereinafter referred to as oil) There is a disadvantage in that it is impossible to prevent the repeated use of the oil of the level itself. For example, if the fry product or edible oil product exceeds the acid value of 3.0, the manufacturer may be subject to administrative disposition, resulting in difficulties in management. Moreover, consumers who eat fry products with an acid value above 3.0 may be harmful to health .

In addition, the fryer or the frying oil inspection apparatus of the patent literature merely provides a display means for informing the manufacturer only of pH (hydrogen ion concentration) due to the acid value of the oil or rancidity of the oil, For example, the operation of stopping the operation of the fryer or the operation of the fryer can not be forcibly controlled until the oil is replaced.

Further, the technology of the patent document can provide the consumer with reliable information such as the degree of rancidity used in the frying product, the frying heating temperature value, the date value corresponding to the manufactured time, and the time value. There is no disadvantage.

Referring to FIG. 2, the quality management apparatus 200 may be a device that manages the frying quality by controlling the operation of the fryer 100 based on the oil acidity value used in the fryer 100.

The quality management module 210 of the quality management apparatus 200 may include a second power supply second central processing unit and a second communication module 217 and may be interlocked with the fry control module 110 described above.

For example, the frying control module 110 also includes a first communication module, and can communicate with the second communication module 217 so that mutual signals can be transmitted and received.

The second communication module 217 is configured to communicate with a third communication module (not shown) of the management terminal 220, which can be configured as a point-of-sale (POS) terminal.

The quality management module 210 includes a signal analysis unit 211 for analyzing a signal. The signal analyzing unit 211 analyzes the signal inputted from the frying control module 110 by the second central processing unit and the second communication module 217 and the acidity measuring instrument 240 which is in contact with or not in contact with the oil filled in the frying tank of the fryer (See FIG. 1 or FIG. 3) and transmits the interpreted signal to the information calculation unit 212.

Here, the signal input from the frying control module 110 may be a button press signal of the fryer, a heating temperature of the thermometer, a timer setting and operation time, a date and time of the clock, and the like.

Also, the quality management module 210 may calculate the heating temperature information, the heater or timer operation start information, the heater or timer operation stop information, the date information, the time information, and the oil acid value And an information calculating unit 212 for calculating the information on the basis of the information.

For example, when the sensor of the acid value measuring device is made of a carbon nano tube (CNT) sensor, the oil value of the information calculating unit 212 is calculated by calculating the degree of souring of the oil based on the resistance value detected from the CNT sensor And can be performed by a general calculation method.

The heating temperature information can be calculated by a predetermined temperature calculation algorithm of the information calculation unit 212 as an average value or a maximum temperature value of the temperature change during the timer operation time as the frying heating temperature value.

Further, the information calculating unit 212 may calculate the frying heating temperature value related to the operation of the heater or the timer from the heating temperature information, the date value and the time value corresponding to the frying time of the heater or timer operation from the date information and the time information Together with the oil rustiness value, to the output request unit 213.

The information calculation unit 212 also calls the additional information value from the memory before printing the label sheet, and transmits the additional information value to the output request unit 213.

Here, the heater or timer operation start information is used as a control value for controlling the oil check of the rust preventer 240.

In addition, the heater or timer operation stop information is used as a control value for controlling a print request of the label printer 230 or 130.

Further, a design, a character, a design drawing, and the like can be further printed on the label 250.

4 is a cross-sectional view of the fryer shown in Fig.

Referring to FIG. 4, the fryer 100 may include a quality control module 210 and a frying control module 110 electrically connected to each other, as described above.

In addition, the body 102 of the fryer 100 is provided with a rancidity meter 240 for measuring the oil acidity value of the hot water tank 101.

The acidity meter 240 includes a sensor 241 located at the top of the oil. The sensor 241 may be a PEI (polyethylenimine) coating that exhibits a high degree of recovery when coated on the surface of the sensor 241 so that it can be repeatedly measured by applying CNT (carbon nano tube) .

The sensor 241 is electrically connected to the signal analyzer 211 (see FIG. 2) of the quality control module 210.

A coil type wire may be used for physical or electrical connection between the sensor 241 and the signal analyzer 211 or an electric wire and a cable bay used between a moving object and a fixed controller in factory automation technology. The coiled wire and cable bays can consist of products that can be used safely in harsh environments such as high temperature and high pressure. In addition, the coiled wire connected to the quality control module 210 may be connected to the sensor 241 through a through hole in the device housing 245. Even if the sensor 241 is lifted or lowered by the ascending / descending device 242, the sensor 241 can maintain the connection state with each other because the coiled wire is free to be stretched and contracted due to the structural characteristics thereof.

Further, the sensor 241 is mostly located outside the oil or above the oil, and can be put into the oil only for a short time only for measurement, and then returned to the original position.

To this end, the acidity meter 240 includes an ascending / descending device 242 for ascending or descending the sensor 241. The lifting and lowering device 242 may have a device housing 245 sealed so that the oil of the hot water tank 101 does not flow into the drive motor and the motor controller 244 of the lifting device 242. Here, the drive motor and the drive controller 244 of the ascending / descending unit 242 can be electrically connected to the sensor moving unit 214 (see FIG. 2) of the quality control module 210.

The ascending / descending device 242 may be a ball screw conveying device or a linear moving robot that converts the rotational motion into linear motion. For example, the ball screw transfer device is advantageous in terms of precision movement and rapid ascending and descending, and particularly oil of the hot water tank 101 can be used as a lubricant, which makes maintenance easy.

In particular, most of the lifting device 242 is located outside the hot water bath 101 and is protected by the device housing 245. However, since only the ball screw shaft of the lifting and lowering device 242 and a part of the lower portion of the bearing are located inside the hot water tank 101, the thermal load generated when heating the oil can be minimized. Of course, the sensor 241 and the ascending / descending device 242 can be made of a material that can withstand the thermal load generated when the oil is heated.

The acidity meter 240 may include a sensor cleaner 243 located at a position corresponding to the start or return point of the sensor 241 and cleaning the oil on the surface of the sensor 241.

The sensor cleaner 243 may be coupled to the sensor cleaner driver 215 of the quality control module 210. At this time, the sensor cleaner 243 may be a high-pressure air or high-pressure gas spraying method, a heating method using a preheating heater, a wiping method using a cleaning cloth, or the like.

The quality control module 210 drives the acidity meter 240 in accordance with the start or stop of the operation of the heater or the timer provided in the fryer 100.

That is, the acidity meter 240 lowers the sensor 241 through the ascending / descending device 242 to partially submerging the oil in the hot water tank 101, and the sensor 241, To the signal analyzing unit of the module 210. Here, the measurement principle of the sensor 241 may be proportional to the increase or decrease in the resistance value of the CNT sensor which is the sensor 241.

The sensor 241 can be used in this embodiment as long as it is capable of repeatedly and reliably measuring or measuring the oil quality of the fryer in addition to the sensor 241 mentioned above.

Thereafter, the acidity meter 240 raises the sensor 241 through the ascending / descending device 242 and allows the sensor 241 to escape from the oil in the hot water tank 101.

Further, the sensor cleaner 243 cleans the surface of the sensor 241 after the measurement.

The acidity measuring instrument 240 may be designed as an optical instrument in addition to the mechanical or resistance measuring instrument described above.

Fig. 5 is a flowchart for explaining a fryer shown in Fig. 1 and a method by its quality control apparatus.

Referring to FIG. 5, a method of controlling oil quality of a fryer includes a step (S100) of connecting a fry control module and a quality control module to each other when main power is applied to the fryer. In this step S100, it is a state before the heating or preheating of the heater is performed, and it becomes a kind of standby state for operation.

The frying control module receives input signals through various buttons, timers, switches, and the like provided in the fryer, and performs a setting process to use predetermined functions. Here, the setting process may refer to a process in which a maker (e.g., a fryer user) sets a predetermined frying setting time (e.g., heater operation time) for each food ingredient.

Thereafter, the user presses the fry start button provided on the fryer.

Then, after the user puts the raw material of the food into the frying net, the frying net is put into the oil of the oil bath.

Thereafter, the user presses the fry start button provided on the fryer.

In this case, the input signal for pressing the fry start button is input to the signal analyzing section of the quality control module via the frying control module as a signal corresponding to the starting point of operation of a kind of heater or timer.

Here, the signal analyzing unit of the quality management module performs the fryer operating signal analyzing step (S200). In the fryer operation signal analyzing step (S200), the signal analyzer interprets the signal and recognizes the start of operation of the heater or the timer of the fryer.

The quality control module then performs a step S300 of measuring the oil acidity value against the oil filled in the oil bath of the fryer through the sensor of the acidity meter.

In step S300 of measuring the oil acidity value, the acidity meter is operated on the basis of the start time of the recognized heater or timer operation, and the sensor of the acidity meter measures the oil acidity value of the oil filled in the oil bath tank do.

Thereafter, the quality control module compares the measured oil rust value with any one of the reference values 2.5 to 2.9, which is previously recorded and managed in the memory of the quality control module (S400). The reference value 2.5 to 2.9 may be a detection value that can be detected by an acid value measuring instrument or a sensor capable of measuring oil acidity.

If the oil acidity value is below the reference value, the quality control module maintains the operation of the heater of the fryer and informs the label of at least one of the date value, the time value, the frying temperature value, A step S500 of requesting label output to the management terminal label printer or the fryer dedicated label printer connected to the quality management module is performed.

Here, the starting point of the step S500 of requesting the label output may be the timer operation ending point corresponding to the time point at which the frying setting time set in the timer ends after the timer starts to operate as the frying start button is pressed .

In addition, the quality control module carries out the step S600 of cleaning the sensor returned by the lifting / lowering device with the sensor cleaner after completing the oil rust measurement.

On the other hand, if the measured oil acidity value is equal to or higher than the reference value, the quality control module transmits a heater operation stop signal to the frying control module (S700).

In this case, the fryer preferentially recognizes the heater operation stop signal of the quality control module and stops the heater.

Further, the quality control module performs a step S800 of transmitting the fryer oil replacement signal to the frying control module.

In this case, the fryer displays a warning corresponding to the fryer oil replacement signal through the operation indicator lamp.

As described above, the quality control apparatus of the fryer or fryer according to the embodiment of the invention can print reliable information such as rancidity and the like on the label and attach it to the packaging box, thereby maximizing the reliability of the edible and preserved processed product.

In addition, in this embodiment, when the oil quality is degraded, the operation of the fryer is forcibly stopped so that the oil can be necessarily replaced at the fryer.
