Description

Heat pump for deep frying oil

The present invention relates to a heat-resistant pump for frying oil, and more specifically, pumps high-temperature cooking oil contained in a frying container for frying food for frying, supplies it to a microbubble machine, and the high-temperature cooking oil supplied to the microbubble machine is a microcomputer. By allowing bubbles to be re-supplied in the frying container, the frying time required to fry the frying food is reduced, and less cooking oil is penetrated into the frying food. It relates to a heat-resistant pump for frying oil.

Generally, a pump refers to a machine that transports a fluid through a tube using pressure action, and a fluid in a liquid or gas flows through a tube into a high pressure container through a tube by using a pressure action. It is a machine to send pressure.

In addition, pumps are widely used for the purpose of transporting not only water but also special fluids such as oil and various chemicals.

The pump of Patent No. 10-0968482 of the prior art is composed of a structure in which the motor and the impeller are embedded in the pump body in an isolated state by a partition wall.

The above-described pump of the prior art may be used for pumping and transporting oil and chemicals, etc., which maintain room temperature, such as water or water, but transporting may be performed when the fluid to be pumped is heated to a high temperature of about 170 ° C or higher. It becomes difficult.

As an example, there are various types of food, and fried food is the most popular food among the food.

Conventional tempura cooking refers to food that is fried in edible oil with fish or meat, vegetables, etc. in flour or frying powder using edible oil containing various ingredients. It must be heated to be able to fry food deliciously.

However, since the pump of the prior art is built in a state in which the motor and the impeller are isolated by a partition wall, the impeller rotates when the edible oil heated at a high temperature is pumped by the rotating operation of the impulse. A phenomenon in which the motor is heated by the high temperature cooking oil flowing into the pumping space appears, and when this heating phenomenon continues, the motor burns and causes a malfunction.

On the other hand, heat-resistant motor pumps are introduced in Patent No. 10-1284670.

The above-described prior art heat-resistant motor pump is used to transport raw materials heated to high temperatures because they are manufactured using raw materials that can withstand high temperature environments such as fire protection clothing and various reinforced plastics used to prepare for fire or explosion accidents.

The heat-resistant motor pump as described above is very expensive because it is specially manufactured in a structure in which a front flange is installed between a stator unit having a high heat-resistant winding wire and a front housing with an impeller.

For this reason, the ultra-high-temperature heat-resistant motor pump can be used to manufacture a special fire protection suit to prepare for a fire or explosion, but it is not used for pumping and supplying high-temperature cooking oil for cooking fried foods. That is true.

The high-temperature cooking oil re-supplied to the frying container 9b in a state in which the ultra-fine bubbles generated by the microbubble machine 9b are mixed is rapidly heated to a high temperature (about 170 ° C) set by the action of the ultra-fine bubbles. In addition, the ultra-fine air bubbles contained in the cooking oil heated to a high temperature penetrate into the fried food, so that the fried food is quickly cooked to shorten the frying time.

With the present invention configured as described above, upon heating of the frying container 9a containing the cooking oil, the cooking oil is not only shortened to the time at which the cooking oil is heated to a set high temperature (around 170 ° C) but also to reduce the frying time of the fried food. The description is as follows.

The heat-resistant pump (1) is composed of a structure in which the motor body (2a) and the pump body (2b) are formed in a separate state and coupled with a coupling (5), so the suction passage of the pump body (2b) ( The edible oil heated at a high temperature in the frying container 9a through the suction pipe 91 connected to 7a) is sucked into the pumping chamber 22, and the edible oil at high temperature is discharged through the connection passage 71 to the discharge passage 7b. On the other hand, the first to third hermetic packings 81, 82, 83 and the heat-resistant support drum 84, even if high-temperature cooking oil sucked into the pumping chamber 22 flows into the pumping chamber 22, Each of them is made of a material such as a ceramic material that can sufficiently withstand high temperatures, and thus is resistant to high temperatures, and the first to third hermetic packings 81, 82, 83 are resilient by the elasticity of the coil spring 88. It completely blocks the leakage of high temperature cooking oil.

In addition, since the motor body 2a is connected at a predetermined distance from the pump body 2b by a coupling 5, high temperature cooking oil is introduced into the pumping chamber 22 of the pump body 2b. Even if there is a high temperature cooking oil heat does not conduct 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 can be free from failure due to the high temperature heat.

On the other hand, the pump body (2b) is supported by the plurality of bearings (41) that are closely connected to each other to the bearing housing (4) formed on the support (3), so that the coupling is supported to perform a rotational operation while maintaining the horizontal (5) is coupled to maintain the horizontal with the motor shaft 21 of the motor body (2a), and accordingly, the pump body (2b) is able to accurately receive the rotational power from the motor body (2a).

As described above, the present invention allows the pump body 2b of the heat-resistant pump 1 to suck high-temperature cooking oil contained in the frying container 9a and supply it to the microbubble device 9b as shown in the embodiment shown in FIG. 6. When the microbubble machine 9b generates ultra-fine air bubbles in the high-temperature cooking oil discharged and supplied from the pump body 2b, the high-temperature cooking oil generated by the microbubble machine 9b is a supply pipe. Since it is re-supplied and heated to the frying container 9a through 93, the ultra-fine bubbles that are evenly distributed and distributed in the cooking oil re-supplied to the frying container 9a increase the boiling point of the cooking oil, and the cooking oil is set to the set temperature. There is an effect that can shorten the heating time.

In addition, the ultra-fine air bubbles spread evenly in the cooking oil penetrate into the fried food, and the fried food is quickly cooked, thereby reducing the frying time of the fried food and frying is completed. Food has the effect of making the cooking oil less crunchy so you can feel the crispy taste of fried food.
