Description

Heat pump for deep frying oil

The present invention relates to a heat-resistant pump for frying oil, and more particularly, pumping high-temperature edible oil contained in a frying container for frying food for frying and supplying it to a microbubble, and the high-temperature edible oil supplied to the microbubble includes micro By allowing it to be resupplied to the frying container in a state in which bubbles are generated, it reduces the frying time required to fry food for frying, less edible oil penetrates into the fry food, and makes it possible to cook the fried food better. It relates to a heat-resistant pump for frying oil.

In general, a pump refers to a machine that transports fluid through a pipe using a pressure action. The fluid in a low-pressure container is transferred through a tube into a high-pressure container by a pressure action. It is a pressurized machine.

In addition, pumps are widely used for transporting special fluids such as oil and various chemicals as well as water.

The pump of the prior art patent No. 10-0968482 has a structure in which a motor and an impeller are separated by a partition wall in the pump body.

The above-described prior art pump can be used for pumping and transporting oil and chemicals that maintain room temperature, such as water or water, but transport is not possible when the fluid to be pumped is heated to a high temperature of around 170°C. It becomes difficult.

As an example, food dishes are prepared in various types, and tempura is the most popular food among food dishes.

Conventional fried food refers to foods that are fried in cooking oil by spreading fish, meat, vegetables, etc. in flour or frying powder using cooking oil containing various ingredients. At this time, the cooking oil used for frying food is usually at a high temperature of around 170℃. It must be heated to make the food deliciously fried.

However, since the pump of the prior art is built in a state in which the motor and the impeller are separated by a partition wall, the impeller rotates when the edible oil heated to a high temperature is pumped by the rotational operation of the impeller. A phenomenon in which the motor is heated by the high temperature cooking oil flowing into the pumping space occurs, and if this heating phenomenon continues, the motor burns, causing failure.

On the other hand, the heat-resistant motor pump is introduced as Patent No. 10-1284670.

The heat-resistant motor pump, which is the prior art, is used to transport raw materials heated to high temperatures because it is manufactured using raw materials that can withstand high temperature environments such as fire protective clothing or various reinforced plastics used to prepare for fire or explosion accidents.

The heat-resistant motor pump as described above is specially manufactured in a structure in which a front flange is spaced between a stator unit in which a high heat-resistant winding wire is embedded and a front housing in which an impeller is embedded, and thus is quite expensive.

Therefore, the heat-resistant motor pump, which is extremely expensive as described above, can be used to manufacture special fire protection suits to prepare for fire or explosion, but it is not used for pumping and supplying high-temperature cooking oil for cooking fried food. There is a situation.

A specific embodiment of a heat-resistant pump for frying oil according to the present invention will be described in detail with reference to the accompanying drawings.

Reference numeral 1 denotes a heat resistant pump, and the heat resistant pump 1 is formed separately into a motor body 2a and a pump body 2b.

The motor body 2a is a driving source that is driven by receiving power from the outside, and a rotating motor shaft 21 protrudes to a predetermined length on one side thereof.

The pump body 2b has a pumping chamber 22 protruding from one side thereof, and a pump cover 23 is assembled at an open portion of the pumping chamber 22.

The pumping chamber 21 of the pump body 2b is fixedly installed on a circular protrusion 31 protruding from one side (refer to the right in the drawing) of the support 3.

In addition, the pump shaft 24 of the pump body 2b is rotatably supported by a retainer 32 formed to be located inside the circular protrusion 31 of the support 3 and is installed so as to penetrate the support 3 Has been.

The bearing housing 4 is fixedly protruding from the other side of the support 3 (refer to the left in the drawing), and the pump shaft 4 is rotatably supported on the inside of the bearing housing 4 to support the pump shaft 24. A plurality of bearings 41 rotatably enclosing 24 are installed.

The characteristics of the present invention are the motor shaft 21 extending to protrude at a predetermined length toward one side of the motor body 2a (refer to the right in the drawing), and one side of the pump body 2b (refer to the left in the drawing). The pump shaft 24 protruding toward a certain length is formed to protrude in a direction facing each other and is configured to be connected and coupled by a coupling 5.

In addition, the support 3 for supporting the pump body 2b in a fixed state is provided in a fixed position spaced apart from the motor body 2a by a predetermined length.

In addition, the pump cover 23 is detachably assembled by bolts or the like in the opening (not shown) of the pumping chamber 22 formed in the pump body 2b.

The pump shaft 24 coupled to the motor shaft 21 by a coupling 5 passes through the bearing housing 4 and the support 3 and extends to the open portion of the pumping chamber 22 at the end of the key coupling portion (24a) is formed, and the key coupling portion 24a of the pump shaft 24 is inserted into a key insertion hole 61 formed in the center of the impeller 6. Accordingly, the impeller 6 is connected to the key coupling portion 24a of the pump shaft 24 and is configured to rotate.

In addition, the pump body (2b) is connected to the opening of the pumping chamber (22), the fluid sucked by the rotation of the impeller (6), that is, the suction passage (7a) through which edible oil is sucked and the discharge passage through which the edible oil is discharged ( 7b) is formed in a symmetrical shape, and a connection passage 71 connecting the suction passage 7a and the discharge passage 7b is formed at the opening of the pumping chamber 22 (FIG. 1) Reference)

Inside the pumping chamber 22 of the pump body 2b, the first to third heat-resistant airtight packings 81 and 82 made of ceramic material that can withstand high temperatures while airtightly supporting the pump shaft 24 (83) are in close contact with each other while surrounding the pump shaft (24), and a heat-resistant support drum (84) made of a material capable of withstanding high temperatures is closely connected to the third heat-resistant airtight packing (83), and the heat-resistant A cover 85 is installed at the end of the support drum 84 (refer to the right part in the drawing), wherein the cover 85 is a ring groove 86 formed between the end of the pump shaft 24 and the key coupling portion 24a. It is installed so as to be caught by the coil-type snap ring 87 mounted on (see Fig. 1).

In addition, the cover 85 is installed to be elastically supported on a coil spring 88 that is elastically installed on the outer periphery of the heat-resistant support drum 84 (see FIG. 1).

The impeller 6 has a plurality of blades 62 and 63 protruding at regular intervals on both sides of the circumferential surface of the circumferential surface as shown in FIGS. 4 and 5. 5)

Therefore, when the impeller 6 rotates, the edible oil is sucked through the suction passage 7a by the plurality of blades 62 and 63, and the edible oil sucked through the suction passage 7a is connected to the connection passage 71 It is transferred to the discharge passage (7b) through and discharged (see Fig. 2).

On the other hand, the housing cover 42 is screwed to the end of the bearing housing 4.

The pump body (2b) of the heat-resistant pump (1) is a high-temperature edible oil contained in the frying container (9a) heated from the flame of a heating range (not shown) as shown in Figure 6 through the suction pipe (91). It is configured to be sucked through the suction passage 7a and discharged to the microbubble machine 9b through the discharge pipe 92 connected to the discharge passage 7b, and the microbubble machine 9b is a discharge pipe 92 It is configured to re-supply to the frying container 9a through the supply pipe 93 by generating ultra-fine bubbles in the high temperature edible oil injected through.

The high-temperature edible oil that is resupplied to the frying container 9b in a state in which the microbubbles generated by the microbubbles 9b are mixed is quickly heated to a high temperature (around 170°C) set by the action of the microbubbles. In addition, the ultra-fine bubbles contained in the cooking oil heated to high temperature penetrate into the fried food, allowing the fried food to cook quickly, which shortens the frying time.

With the present invention configured as described above, when heating the frying container 9a containing cooking oil, not only shortening the time for heating the cooking oil to a set high temperature (around 170°C), but also shortening the frying time of fried food. It will be described as follows.

Since the heat-resistant pump 1 is formed in a state in which the motor body 2a and the pump body 2b are separated from each other and is configured to be coupled by a coupling 5, the suction passage of the pump body 2b ( The high-temperature cooking oil in which the cooking oil heated to high temperature in the frying container 9a is sucked into the pumping chamber 22 through the suction pipe 91 connected to 7a) is passed through the connection passage 71 to the discharge passage 7b. While being transported, even if the high-temperature edible oil sucked into the pumping chamber 22 flows into the pumping chamber 22, the first to third heat-resistant airtight packings 81, 82, 83 and heat-resistant support drum 84 Each of them is made of a material such as a ceramic material that can sufficiently withstand high temperatures, so it is resistant to high temperatures, and the first to third heat-resistant airtight packings 81, 82 and 83 are formed by the elasticity of the coil spring 88. It completely blocks the leakage of hot cooking oil.

In addition, since the motor body (2a) is connected to the pump body (2b) by a coupling (5) at a location spaced apart from the pump body (2b), the high temperature edible oil is introduced into the pumping chamber (22) of the pump body (2b). Even if there is, the high temperature cooking oil heat is not conducted to the motor body 2a side, and accordingly, the motor body 2a is not affected by the heat of the cooking oil heated to a high temperature, so it can be free from failure due to the high temperature heat.

On the other hand, the pump body (2b) is supported by a plurality of bearings (41) closely connected to each other to the bearing housing (4) formed on the support (3) so as to rotate in a state maintained horizontally. It is connected and coupled to maintain a horizontal position with the motor shaft 21 of the motor body 2a by (5), so that the pump body 2b can accurately receive rotational power from the motor body 2a.

In the present invention described above, the pump body 2b of the heat-resistant pump 1 sucks the high-temperature edible oil contained in the frying container 9a and supplies it to the microbubble machine 9b as in the embodiment shown in FIG. Then, the microbubble machine (9b) generates ultra-fine bubbles in the high-temperature edible oil discharged and supplied from the pump body (2b), and the high-temperature edible oil generated by the micro-bubble machine (9b) is a supply pipe. Since it is re-supplied to the frying container 9a through 93 and heated, the ultrafine bubbles evenly diffused and distributed in the cooking oil resupplied to the frying container 9a increase the boiling point of the cooking oil, so that the cooking oil is brought to a set temperature. There is an effect of making it possible to shorten the heating time.

In addition, the ultra-fine air bubbles evenly spread and distributed in the cooking oil penetrate into the fried food and act to quickly cook the fried food, thereby reducing the frying time of the fried food. Cooking oil is less cut in food, so you can feel the crispy taste of fried food.
