SUMMARY OF THE INVENTION The present invention relates to a continuous oil-lifting apparatus comprising a raw material carry-in section, an oil lift chamber, endless raw material transport means for transporting raw materials in oil in the oil lift chamber, and a product discharge section. Formula raw material conveying means, a net conveyor, extending outward in the outer surface of the net conveyor and extending in a direction orthogonal to the conveying direction, a cross section forms a triangle, a plurality of holes in the front plate surface portion and the rear plate surface portion. It is a raw material transporting device of a continuous oil-lifting device, wherein the provided projecting portion is provided. Embodiments of the present invention are as follows. A triangle of a cross section of the protrusion is a right triangle, and the front plate surface is substantially orthogonal to the net surface. The outer end of the protrusion is rounded with a radius greater than 1/4 of the minimum diameter of the raw material. A plurality of holes are provided at appropriate intervals at the outer end of the protrusion. The oil-lifting chamber is composed of two tanks, a first oil-lifting tank and a second oil-lifting tank, and the endless raw material conveying means is installed in the second oil-lifting tank.

A hood 1 is provided above the first oil-lifting tank 10 and the second oil-lifting tank 12.
3 are arranged. In the first oil-lifting tank 10, the heating oil is supplied at the first oil supply port 14 in the upstream side wall portion, and the chip raw material A is continuously supplied to the heating oil flowing along the slope of the first oil-lifting tank 10. The second oil-lifting tank 12 is provided with a transport belt 20 for conveying the chip raw material A into the second oil-lifting tank while scraping the raw material A into the second oil-lifting tank, and a discharge conveyor 22 for discharging the fried chips B. The transport belt 20 is an endless net conveyor, and is driven by a driving roller 26, a first guide roller 28, and a second guide roller 30. The transport operation area of the transport belt 20 is arranged in the oil Oi of the second oil fry tank 12.

[0008] On the outer surface of the conveyor belt 20, (a) of FIG.

As described above, it is preferable to stand upright on the outer surface of the transport belt 20, so that the frying can be carried out while transporting the chip raw material in a state where the chip raw material is held in the portion defined by the protrusion 40. The joint between the front surface 32 and the rear surface 34, which is the tip of the protrusion 40, is a cylindrical surface 42 having a radius of 0.6 cm, and the front surface 32, the rear surface 34, and the cylindrical surface 42 are connected with a common tangent plane. I have. Front 32 and rear 34
Has a diameter of 6 mm as shown in FIGS. 3 (b) and 3 (c).
Are provided, the total area (the total number of circular holes) of the circular holes 43 on the front surface 32 is equal to the circular holes 4 on the rear surface 34.
3 is smaller than the total area (total number of circular holes). Thereby, when the chip material A is raked from the first oil tank 10 into the second oil tank 12, it is possible to prevent the chip material A from adhering to the protruding portion 40, and the possibility that the chip material A is deformed or broken is extremely small. There are advantages. If the radius of the outer end of the projecting portion, which is the connecting portion, is larger than １ ／ of the minimum diameter of the chip material A, there is an advantage that the chip material A does not adhere to the projecting portion 40. In addition, minute circular holes 94 having a diameter of 4 mm are provided at appropriate intervals in the coupling portion.
Thereby, there is an advantage that the oil pool at the connecting portion can be prevented.

The protrusion 40 is bolted and nut-fastened to a conveyor chain 41 for driving the conveyor belt 20, and the conveyor belt 20 is sandwiched between the protrusion 40 and the conveyor chain 41. Heated oil is supplied to the second oil lifting tank 12 through a second oil supply port 44 on the downstream side of the bottom. The discharge conveyor 22 is an endless net conveyor,

A new oil tank 86 is connected with a pipe via a new oil supply amount adjusting valve 84. The oil heating heat exchanger 80 is connected to the first oil supply port 14 via a second valve 90 by a pipe, and is also connected to the second oil supply port 44 via a third valve 92 by a pipe.

In the continuous oil fryer 1 having the above-described structure, the oil is heated by the oil heating heat exchanger 80, for example, to 16
The oil Oi that has reached 0 ° C. is supplied to the first oil supply port 14 via the second valve 90 and the second oil Oi is supplied via the third valve 92.
The oil is supplied to the oil tank 12. Oil Oi, which has been cooled down and cooled down, is sent from the oil reservoir 70 to the oil circulation pump 74 via the first valve 72, and new oil is supplied from the new oil tank 86 via the new oil supply amount adjustment valve 84. Supplied. In the first oil-lifting tank 10 inclined downward, the chip raw material A contains oil O
It moves in the direction of the second fry tank 12 while being fried by i. In the second oil fry tank 12, the chip raw material A is moved in the direction of the discharge conveyor 22 while being immersed and fried in the oil Oi by the action of the transport belt 20 and the protruding portion 40. The present invention can be effectively implemented also in a reduced-pressure type continuous frying apparatus.
