Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fryer comprising a frying tank divided into a water tank at the bottom and an oil tank at the top due to the difference in specific gravity between oil and water.

An object of the present invention is to provide a fryer that cools the temperature near the interface between water and oil, maintains the oil at an appropriate temperature during use, and allows water to circulate naturally.

Therefore, the present invention includes a frying tank that contains oil and water and is divided into a water tank at the bottom and an oil tank at the top depending on the difference in specific gravity.
In a fryer having a heating pipe installed in the oil tank, the upper end is located slightly above the interface between oil and water below the heating pipe, and the lower end has several heat transfer plates that reach the deep part of the water tank. A water inlet pipe and a drain pipe are installed vertically and communicated with the lower part of the water tank, and the opening end of the drain pipe is positioned at a predetermined height to serve as an overflow port so that the oil level in the frying tank is always constant. This is a deep fryer characterized by the fact that

In the drawing, 1 indicates a frying tank, which contains oil and water and is divided into a water tank 2 at the bottom and an oil tank 3 at the top depending on the difference in specific gravity. 4 indicates a heating tube placed horizontally in the oil tank 3.

In the present invention, several heat exchanger plates 5 are provided in the frying tank 1.
are erected at required intervals, with the upper end slightly above the oil-water interface a below the heating pipe 4, and the lower end reaching the deep part of the water tank 2. .

A water inlet pipe 6 and a drain pipe 7 that communicate with the lower part of the water tank 2 are installed in the frying tank 1, and the water inlet pipe 6 is inserted into a water supply pipe 8 installed in parallel with the frying tank 1, and its tip is inserted into the water supply pipe 8. The water supply cylinder 8 is opened above the water level, and a ventilation pipe 9 is provided at the upper end side of the water supply cylinder 8.
will be established.

The opening end of the drain pipe 7 is positioned at a predetermined height to form an overflow lower', so that the water level in the frying tank 1 is always constant.

10 is an oil drain valve, 11 is a drain valve, 12 is a net, 13
14 indicates a gas burner, 14 indicates an exhaust pipe, and 15 indicates a water injection valve.

Since the present invention has an upward diagonal configuration, the temperature near the interface between oil and water is absorbed at the upper end of the heat transfer plate, and the heat is transferred downward, thereby cooling the oil and water near the interface. be able to.

That is, by utilizing the difference in temperature between the upper and lower water in the water tank and exchanging heat via the heat exchanger plate, the temperature rise of the oil and water near the interface is prevented.

If the water temperature in the tank rises due to heat exchange, when water is injected through the injection pipe, the excess water will be discharged from the overflow port of the drain pipe, which has the effect of keeping the water level constant and maintaining an appropriate temperature at all times. be.

Claims (1)

[Claims] 1. In a fryer equipped with a frying tank containing oil and water and divided into a water tank at the bottom and an oil tank at the top according to the difference in specific gravity between the two, and a heating pipe installed in the oil tank, the oil and water are placed below the heating pipe. Several heat exchanger plates are erected, the upper end of which is located above the boundary surface of water, and the lower end of which reaches the deep part of the water tank, and a water inlet pipe and a drain pipe that communicate with the lower part of the water tank are installed oppositely. A food frying device characterized in that the opening end of the drain pipe is positioned at a predetermined height to serve as an overflow port so that the oil level in the food frying tank is always constant.
