[0001] VACCUM FRYING APPARATUS [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vacuum low-temperature boiler, and more particularly, to a vacuum low-temperature boiler capable of selectively attaching and detaching an oil storage tank so that oil does not mix with an object to be heated.

Confectionery is a favorite food not only for young children but also for adults, and many kinds have been constantly developed and consumed. Among them, the snack processed by heating is easier to manufacture than other confectioneries, and can be manufactured using almost all materials. Potatoes, sweet potatoes, and starches are examples of typical materials that can be processed as a snack. In particular, starch (flour) is molded into various forms, and most of the processed snacks are treated with various colors and flavors.

Vegetables are foods that are used in fresh form and contain little or no fat and protein, but are rich in vitamin A, C, and inorganic salts that are scarce in diet. Vegetables should be used shortly after harvest because of their very high moisture content and storage limitations. As the importance of the consumption of vegetables has increased, there has been an increase in the number of products to which vegetables are applied in the process of making hot water, which can use almost any material and can be easily taken.

In general, the hot water treatment process is performed under the atmospheric pressure (760 mmHg), the hot water temperature is 140-220 ° C, and the hot water time is 1-15 minutes. However, in the conventional hot water treatment, not only the shape, flavor, and nutrients inherent in the material are destroyed, but also a large amount of oil is left in the product because it is molten in a high temperature oil in a short time.

As a method of manufacturing a snack using a vacuum frying process for vegetables, there have been disclosed a method for manufacturing a potato snack using a raw potato (Korean Patent Application No. 10-2000-0066209), a method for manufacturing a sweet potato chip (Korean Patent Application No. 10 -2005-0010645).

However, there is a problem in that the surface of the snack is hardened due to the hot water process to form a film and oil that does not escape remains, thereby increasing the fat content of the snack and promoting rancidity .

In addition, since the conventional hot water tanks can not replace the oil in the oil tank depending on the objects to be hot-watered, there is a problem in that various kinds of hot water can be mixed with the fried oil, thereby hurting the unique taste and flavor of the hot water object.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems, and to provide a vacuum low-temperature boiler which can easily change oil for each frying subject and prevent mixing oil.

Another object of the present invention is to provide a vacuum low-temperature boiler which is capable of removing oil, thereby increasing the rate of oil removal of the frying product and lowering the content of trans fat in the frying product.

Another object of the present invention is to provide a vacuum low-temperature boiler which can be fired at a low temperature and can reduce the generation of toxic substances generated at a high temperature.

When the oil storage tank 110 is to be replaced, the oil discharge valve 115 is closed as shown in FIG. 2 (b), the oil storage tank 110 is moved after the connection ring 123 is disassembled, ).

By this process, the plurality of oil storage tanks 110 can be easily replaced, and the oil can be exchanged and stored for each object to be heated, thereby preventing mixing oil and maintaining the inherent taste of each object to be heated.

An oil filtering unit 130 may be provided on the path of the oil supply pipe 121 of the storage tank connecting unit 120. The oil filtering unit 130 filters foreign matter or molten residue mixed in the oil supplied from the oil storage tank 110 to the hot water tank 141.

The oil filtration unit 130 may be connected to the oil movement pipe 131 and the oil movement pipe 131 may be connected to the oil supply pipe 121. The oil moving pipe 131 is connected to the hot water tank 141.

In the present invention, the oil filtering unit 130 is provided, but when the oil filtering unit 130 is not provided, the oil supplying pipe 121 of the storing unit connecting unit 120 is directly connected to the oil bath 141.

The oil transfer pipe 131 is provided with a deaeration valve 133 to control whether or not the hot water tank 141 is de-oiled.

The molten part 140 provides a space in which the molten object can be molten in a vacuum state. The hot water tank 140 includes a hot water tank 141 having an adjustable internal pressure and a cover 142 connected to the top of the hot water tank 141 to be openable and closable, A temperature regulator 144 for regulating the temperature of the hot water tank 141 and a vapor transfer pipe 146 for transferring the vapor generated during the hot water supply.

The water tank 141 has a space in which oil is received. The water tub 141 is rotatably coupled to the lower casing 143. The oil removing part (150) is coupled to the lower part of the water tub (141).

A temperature controller 144 is coupled to the outside of the hot water tank 141 to control the temperature of the hot water tank 141. The cover 142 is coupled to the upper part of the hot water tank 141 so as to open and close the hot water tank 141 so that the object to be hot water can be introduced into or discharged from the hot water tank 141.

A vapor movement pipe 146 is provided on a side surface of the water tank 141. A vapor condensation recovery unit 180 is coupled to the vapor movement pipe 146 and a vacuum tank 160 and a vacuum pump 170 are coupled to a lower portion of the vapor condensation recovery unit 180.

The vacuum tank 160 and the vacuum pump 170 apply vacuum pressure to the hot water tank 141 so that the vacuum pressure is maintained while the hot water flows in the hot water tank 141.

The vacuum tank 160 and the vacuum pump 170 supply the cooling water W2 to the vapor condensation recovery unit 180 so that the vapor is condensed. Vapor may contain toxic substances harmful to human body and cause air pollution. Thus, a vapor filtering filter 147 is provided in the vapor moving pipe 146 to filter foreign substances contained in the vapor.

The vapor of the foreign matter is discharged through the vapor discharge pipe 148 and is condensed by the cooling water W2 supplied from the vacuum tank 160 in the vapor condensation recovery unit 180 to be changed into a liquid phase, Is recovered.

The oil removing unit 150 is provided at a lower portion of the hot water tank 141 and forcibly discharges the hot water of the hot water tank 141 to the oil storage tank 110 after the hot water is completed.

For this, the oil removing unit 150 includes a rotating shaft 151 provided at a lower portion of the water tub 141, a rotating motor 153 for generating a rotating driving force, and a rotating shaft 153 for transmitting the driving force of the rotating motor 153 to the rotating shaft 151 And a transmission member 157 for transmitting the torque.

Here, a sealing member 155 for preventing external leakage of oil is provided in the boundary region where the rotary shaft 151 and the hot water tank 141 meet, while the hot water tank 141 is rotatably supported. Since the sealing member 155 rotates at high speed together with the rotating shaft 151, it can be deformed by friction and heat. When the sealing member 155 is deformed, leakage of oil may occur. In order to prevent this, the cooling water W1 is supplied to the sealing member 155 in the present invention.

The cooling water W1 is supplied along the periphery of the sealing member 155 and then discharged, thereby cooling the heat of the sealing member 155.

A process of making a hot water using the vacuum low-temperature and high-pressure water heater 100 according to the present invention having such a configuration will be described with reference to FIGS. 1 to 3. FIG.

I am going to improve after I put on the object of the watering for the boiling. Then, the object to be heated is washed and molded. After the washing and molding are completed, the object to be heated is subjected to a process of gyrating and quenching.

The operator joins the oil storage tank 110 to the storage tank connection portion 120, which is suitable for the object to be heated. As shown in FIG. 3, after the connection ring 123 is disassembled, the oil discharge pipe 113 and the oil supply pipe 121 are disposed coaxially with each other, and the coupling ring 123 is tightened to complete the coupling.

The cover 142 is opened and the object to be heated is introduced into a cooking net (not shown) inside the hot water tank 141. The cover 142 is closed and the vacuum pump 170 is operated. The inside of the hot water tank (141) is evacuated gradually by the operation of the vacuum pump (170).

When the oil discharge valve 115 of the oil storage tank 110 is opened, the oil in the oil storage tank 110 flows into the hot water tank 141 by the vacuum pressure inside the hot water tank 141. When the proper amount of oil flows into the hot water tank (141), the oil discharge valve (115) and the deaerating valve (133) are closed.

The temperature controller 144 gradually increases the temperature inside the hot water tank 141. [ When the vacuum pressure inside the hot water tank 141 reaches 960 b, the oil in the hot water tank 141 is boiled at a low temperature of 85 to 90 ° C, and the object to be heated is fried.

The object to be heated can be heated at 175-180 ° C under atmospheric pressure. However, in the vacuum low-temperature and high-pressure water heater 100 of the present invention, since the inside of the hot water tank 141 is heated in a vacuum state, hot water can be supplied at a low temperature of 85 to 90 ° C. As a result, it is possible to preserve the inherent color and weak inherent nutrients of the object to be heated, and to significantly reduce the generation of carcinogenic substances such as acrylamide and benzo-pyrene which are generated at the high temperature.

When the oil starts to boil, the hot water is fed for a time suitable for the hot water to be hot water. For example, onions are 8 minutes and 20 seconds, sweet potatoes and potatoes are 15 minutes, mushrooms are 12 minutes, and bits are 8 minutes.

When the set cooking time has elapsed for each object to be heated, deaeration proceeds with maintaining the vacuum pressure. When the degreasing valve 133 and the oil discharge valve 115 are opened and the rotary motor 153 is driven, the hot water tank 141 rotates at a high speed. Centrifugal force is generated by the rotation of the water tank 141 and the oil moves along the oil movement pipe 131 and the oil supply pipe 121 and is returned to the oil storage tank 110.

Since the degreasing part 150 is subjected to a forced degreasing process, the rate of degreasing of the hot-water product is increased, so that the palm oil is little in the product and the content of trans fat can be lowered.

When the deoiling process is completed, the cover 142 is opened and the operator discharges the hot-water product stored in the cooking net (not shown) to the outside. Bottled products can be sold to consumers after packaging.

As described above, the vacuum low-temperature boiling machine according to the present invention includes a plurality of oil storage tanks for each object to be heated, and an oil storage tank corresponding to the object to be heated can be selectively detachably coupled to the storage tank connection portion.

The reservoir connection is provided by a sanitary pipe and can be safely connected to the oil reservoir without leakage. Thus, the oil storage tank itself can be easily replaced, so that the hot water can be advanced without mixed oil for each hot water object, and the quality of the hot water can be improved.

Further, after the hot water is completed, the forced de-oiling process is performed by the oil removing part to improve the rate of oil removal of the hot water product.

The embodiments of the vacuum low-temperature and high-pressure heater according to the present invention described above are merely illustrative and those skilled in the art will appreciate that various modifications and equivalent embodiments can be made without departing from the scope of the present invention. You will know. Therefore, it is to be understood that the present invention is not limited to the above-described embodiments.
