Description

Technical Field

[0001] This utility model relates to the field of pressure fryers, specifically to a melt-oil pressure fryer. Background Technology

[0002] Traditional frying technology heats food at high temperatures in oil, giving it a crispy texture and golden color. However, high temperatures easily produce harmful substances, generate a lot of oil fumes, are energy inefficient, and have a high oil absorption rate. Pressure fryers, on the other hand, use a sealed pot with a vacuum device to create a negative pressure environment inside, lowering the boiling point of the oil. Low-temperature frying reduces the formation of harmful substances, inhibits cell rupture in food, and reduces oil absorption. Furthermore, with the addition of temperature sensors and frequency converters, the heating element power can be dynamically adjusted to avoid continuous high-temperature energy consumption.

[0003] However, this type of frying device cannot melt solid oil itself; it requires the solid cooking oil to be melted into liquid before being poured into the pot, which is very inconvenient. It also requires additional oil melting equipment, which is detrimental to kitchen space utilization and significantly increases costs. Furthermore, it necessitates transporting large quantities of hot liquid oil into the fryer's pot, which is physically demanding for operators and poses safety risks. Based on the aforementioned technical problems of existing technologies, the inventors, drawing on years of research and development experience, propose an oil-melting pressure fryer. Utility Model Content

[0021] The utility model of this application will be further described in detail below with reference to the accompanying drawings and specific embodiments. In order to provide a clear and complete description of the technical solution, the following embodiments are selected for illustration; other embodiments obtained based on the content described in this application without creative effort are all within the scope of protection of this utility model.

[0022] In the following embodiments, it should be noted that the terms "upper", "lower", "left", "right", "inner", "outer", "top / bottom" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of clearly describing this embodiment, rather than indicating or implying that the device or element referred to must have a specific orientation, and therefore should not be construed as a limitation of this application.

[0023] like Figure 1-7 As shown, the specific embodiment of this utility model is: a melt-oil pressure fryer, comprising a housing 1 and an electrical control unit 11. The housing 1 is used to support and accommodate various components. The bottom of the housing 1 is provided with support feet 12, casters 13 and small pulleys 14 for easy movement.

[0024] The box 1 is equipped with a pot body 2 for holding cooking oil. A sealing lid 5 is provided on the upper part of the pot body 2. The sealing lid 5 is hinged to the top of the box 1 and is fastened and sealed with the pot body 2. The sealing lid 5 is equipped with a latch 16 with a cross handle. The upper part of the pot body 2 is equipped with a corresponding locking tongue 15. The latch 16 and the locking tongue 15 are fastened together to achieve a tight lock.

[0025] The pot body 2 has a columnar groove structure in the middle and a concave groove structure at the bottom, which is wider at the top and narrower at the bottom, specifically an inverted quadrangular frustum shape. This allows the oil at the bottom to collect and flow into the drain groove 17 when draining waste oil. Three layers of rectangular annular heating tubes 3 are installed around the inner wall of the pot body 2 to evenly heat the liquid cooking oil for frying. A temperature sensor 4 is installed inside the pot body 2 to monitor the oil temperature and provide feedback to the electronic control unit 11. An oil drain port 6 is located at the bottom of the pot body 2.

[0026] To ensure safer and more efficient automatic oil melting, a melting heating mechanism 7 is installed on the outer bottom of the pot body 2 to melt solid edible oil into liquid edible oil. The melting heating mechanism 7 includes four corrugated melting heating tubes 701, arranged around the oil drain assembly. The melting heating tubes 701 are fixed by fixing grooves 704 on the fixing bracket 702 and secured to the outer bottom wall of the pot body 2 with screws or welding to enhance heat conduction. A lower cover plate 703 is installed on the outer bottom of the pot body 2, covering the melting heating tubes 701 and the oil drain assembly, providing protection and insulation. The oil drain assembly consists of an oil drain trough 17 and an oil drain pipe 8. The oil drain trough 17 communicates with the pot body 2, and the oil drain pipe 8 is located below the oil drain trough 17. The end of the oil drain pipe 8 has a threaded interface for easy connection to an external container. The electronic control unit 11 is electrically connected to the annular heating tube 3 and the oil melting heating mechanism 7. After the oil melting heating mechanism 7 melts the solid edible oil into liquid edible oil, the electronic control unit 11 turns off the heating of the oil melting heating mechanism 7 and turns on the heating of the annular heating tube 3.

[0027] In order to better control the pressure inside the pot 2 during cooking, a vacuum pump for adjusting the pressure inside the pot 2 is also installed in the box 1. It is connected to the pot 2 through a connecting pipe, and a pressure gauge 9 and a control valve 10 are installed on the connecting pipe to realize pressure monitoring and adjustment.

[0028] To facilitate monitoring of cooking parameters, an electronic control unit 11 is installed on the front of the cabinet 1 to control the operating parameters of the annular heating tube 3, the melting oil heating mechanism 7, and the vacuum pump.

[0029] In use, simply add solid edible oil to the bottom of the pot body 2. The bottom of the pot body 2 is heated to about 200°C by the melting oil heating tube 701 on the outer side of the bottom. At this point, the solid edible oil (such as shortening, with a melting point of about 40°C and a flash point of about 340°C) is in full contact with the bottom of the pot body 2, allowing it to melt safely and quickly at its melting point. Compared to traditional room temperature melting, this saves more than half an hour. Compared to traditional heating melting, it eliminates the transfer process, making operation safer, requiring less equipment, and saving space. When the solid edible oil melts and reaches the designated height to immerse the temperature sensor 4, the temperature sensor 4 can monitor the oil temperature inside the pot. Once the edible oil in the pot reaches the designated temperature, the melting oil heating tube 701 is automatically turned off, and the annular heating tube 3 is activated to continue heating the edible oil. The fryer of this application does not require the solid edible oil to be melted first; the entire operation is completed in one step, which can significantly improve the working efficiency and operational safety of the fryer.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any minor modifications, equivalent substitutions and improvements made to the above embodiments based on the technical essence of the present utility model should be included within the protection scope of the technical solution of the present utility model.
