取出される。 The deodorizing process of fats and oils is generally carried out in a vacuum deodorizing tower in order to enhance the treatment effect. The raw material oil fed into this deodorizing tower is usually at a temperature of about 40 to 80°C.
This raw material oil to be treated is first stirred and heated to about 170 to 180°C in a steam heating tray in this column, and then stirred and heated to about 230 to 270°C in the next heating tray. After that, several stages of stirring and deodorization are performed, and then the tower is cooled down to approximately 60° to 70°C with cooling water.
After low-temperature deodorization treatment, it is taken out of the vacuum deodorization tower as a product oil.

る。 In this method, raw oil at 40 to 80 degrees Celsius must be heated to about 230 degrees Celsius or higher (usually 260 degrees Celsius), where the deodorizing effect occurs, and then cooled again to about 60 to 70 degrees Celsius, which consumes a lot of energy. This required a lot of energy loss. Therefore, in order to reduce such large amounts of energy consumption and prevent energy loss, it is advantageous to perform more effective heat recovery from the fats and oils in the deodorizing tower.

的に同一である。 In the figure, feedstock oil at about 40 to 80° C. is supplied into a vacuum deodorizing tower 10 via a supply pipe 12 by known means. The raw material oil supplied into the deodorizing tower 10 is first received in the preheating tray 14. The tray 1
4 is provided with a steam pipe 16, whereby the oil in the tray 14 is stirred and heated to about 170 to 180°C. The raw material oil heated in this tray 14 enters the heating tray 18 below. A steam pipe 20 is similarly disposed within this tray 18, whereby the oil heated to 170-180°C is further stirred and heated to an effective deodorizing temperature of 230-270°C. Next, the stirred and heated oil to be deodorized is stirred in a plurality of deodorizing trays 22, 22, 22, and passes through these trays one after another, where odoriferous substances are decomposed and deodorized. The high temperature deodorized oil in these deodorizing trays, preferably at about 260° C., then flows from the final deodorizing tray 22 into a heat recovery tray 24 where the oil is deodorized by cooling water supplied via pipes 26. It is cooled to 210-230°C to perform low-temperature removal of odorous substances. Thereafter, the oil is further cooled to 60 to 70°C by a cooling tray 30 through which a pipe 28 for introducing cooling water is connected, and then taken out from the deodorizing tower 10 as a product oil. Note that odorous substances and the like are discharged from the upper pipe 32 of the deodorizing tower 10 to the outside of the system. The operation of this deodorizing tower 10 is substantially the same as that disclosed in Japanese Patent Application No. 10673/1983 filed earlier by the same applicant.

成る横型円筒で、その構造が極めて簡便である。 The room-temperature cooling water supplied into the deodorizing tower 10 through the cooling pipe 26a exchanges heat in the heat recovery tray 24 with oil at about 260° C. which has now undergone high-temperature deodorization. The cooling pipe 26a is disposed in the tray 24 in the form of a coil, preferably divided into four series each having several turns to improve heat exchange efficiency. Therefore, the high temperature oil (approximately 260°C) that has entered the heat recovery tray 24 is kept at a predetermined high pressure (P
Cooling water (room temperature) made of soft water supplied via the pipe 26a from the water supply tank 38 which is pressurized to Kg/cm 2 G) is heated to about 210° to 230°. Therefore, the cooling water that has exchanged heat with the oil and fat by the coil-shaped heat exchange element in the tray 24 is vaporized and generates steam when it leaves the tray 24. The steam of PKg/cm 2 G generated here is guided to the steam/water separator 36 via the pipe 26b. This separator 36 consists of a hollow, elongated sealing member, and functions to separate the vapor introduced from the vapor introduction section 36a into a gas portion and a liquid portion. The separated gas components are supplied from the gas component supply section 36b to the external pipe 44 via the pipe 46, and are used as desired steam lines, respectively.
On the other hand, the separated liquid portion is discharged from the liquid portion discharge portion 36c.
The water is then returned into the water supply tank 38. This steam/water separator 36 of the present invention has an introduction section 36 as shown in the figure.
It is a horizontal cylinder made of a sealed hollow member, and its structure is extremely simple.

る。 The water supply tank 38 to which the liquid separated from the steam in the pipe 26b returns is simply a horizontal cylinder, and the water level in the water supply tank 38 is constantly monitored by the level transmitter 40.
It is detected by. When the transmitter 40 detects a decrease in the water level, the transmitter sends a signal to that effect, and in response to the signal, the valve 4 connected to the soft water source is activated.
2 is designed to open and close, and the water tank 38
The water level inside is always kept constant. In the present invention, this water level is always located above pipe 26b. As a result, the soft water to the tubes 26a, 26b and the heat exchange coil portion of the tube 26 of the heat recovery tray 24 can be supplied by gravity simply by the weight difference based on the water level difference, and no complicated pressure supply mechanism or control is required. No equipment required. Note that the pipe 48 is the external pipe 4.

Let's change. On the other hand, the water supply tank 38 made of a horizontal cylinder can have an inner diameter of 900 mm or more and a length of 1500 mm or more, and the height difference between the liquid level of the tank 38 and the pipe 26b is about 800 mm or more.
