A sleeve 94 located between them is provided so as to be movable in the axial direction via key means (not shown).

In the annular groove 95 in the approximate center of the sleeve 94,
The forked portion 9 at the tip of the nearly L-shaped operating lever 96
7 is engaged. The operating lever 96 has a bent portion attached to the pedestal 80 via a pin 98 so as to be horizontally rotatable, and an operating portion 9 at the other end.
9 protrudes to the left of the pedestal 80.

Between the sleeve 94 and each of the left and right sprockets 93 is a clutch 10 made of dog clutch teeth.
0 is provided for each. Therefore, by rotating the operating lever 96, the sleeve 94 is moved on the transmission shaft 84, and this movement selectively connects the transmission shaft 84 and one sprocket 93 via the clutch 100. Ru.

Left and right speed change sprockets 101 and 102 are mounted approximately at the center of the rear transmission shaft 85 at a predetermined distance. The left speed change sprocket 101 is set to have a larger number of teeth than the right speed change sprocket 102. An endless transmission chain 103 is attached to each speed change sprocket 101, 102 and each sprocket 93 on the transmission shaft 84, respectively. Therefore, the operating lever 9
6, the rotation of the front transmission shaft 84 is transmitted through a transmission mechanism mainly consisting of the right transmission chain 103 or a transmission mechanism mainly consisting of the left transmission chain 103. , is transmitted to the rear transmission shaft 85.

Note that the number of teeth on each sprocket involved in driving each of the conveyors 1, 2, and 3 is selected appropriately, and under normal conditions, that is, when the sleeve 94 is connected to the right speed change sprocket 102, each conveyor The conveying speeds (so-called circumferential speeds) of each of the conveying members 1, 2, and 3, that is, the conveying roller 14, the feeding belt 28, and the presser belt 62 are set to be approximately the same speed. Therefore, when the sleeve 94 is connected to the left speed change sprocket 101, the number of teeth on the sprocket 101 is greater than that of the right speed change sprocket 102, so that the rotation of the front transmission shaft 84 is caused by the rotation of the rear transmission shaft 8.
5, the conveyance speed of the fried food holding conveyor 3 is lower than the conveyance speed of the fried food conveyor 1.
transport speed is reduced. Note that the sleeve 94 is not connected to the speed change sprocket 101 (or 1
02), and the transmission chain 103 idles.

In the above-described deoiling machine for frying, the sleeve 94 of the transmission 6 is now connected to the right transmission sprocket 10.
2, and when the drive motor 81 is rotated in this state, the rotation is caused by the transmission mechanism mainly consisting of the drive chain 88 and the front transmission shaft 8.
4. The front and rear fried material conveyor 1 and fried material input conveyor 2 are operated through a transmission mechanism mainly composed of the conveyor drive chain 90, and the conveyor 1,
The two transport members, namely the transport roller 14 and the feed belt 28, are rotated. At the same time, through a transmission mechanism mainly consisting of the transmission chain 103 on the right side of the transmission 6, a transmission mechanism mainly consisting of the transmission shaft 85 on the rear side, a transmission mechanism mainly consisting of the conveyor drive chain 92, and a transmission mechanism mainly consisting of the transmission chain 71, , the front and rear fryer presser conveyors 3 are operated, and each presser belt 62 of the conveyor 3 is rotated. At this time, the conveyance speeds of each conveyor 1, 2, and 3 are the same speed.

In the operating state of the conveyor described above, when fried food, especially flat fried food F, is thrown onto the feed belt 28 of the rear fried food input conveyor 2, the rotation of the feed belt 28 causes the fried food F to move forward (the first (to the right in Figure 1). It should be noted that the fried food F fed into the deep-fried food deoiling machine has just been fried manually or by an automatic deep-frying machine.

The fried food F is pressed onto the feed belt 28 with a predetermined pressing force by the pressing belt 62 of the fried food holding conveyor 3, and is sent to the fried food transport conveyor 1 in front of the feeding belt 28.

Thereafter, the fried food F is held between the conveyance roller 14 of the fried food conveyor 1 and the presser belt 62 of the fryer presser conveyor 3, and moves forward by the rotation of the conveyor roller 14 and the presser belt 62. being transported. The fried food F sent forward passes over the guide plate 34 and reaches the fried food input conveyor 2 on the front side.
(See the two-dot chain line in FIG. 1).

The inverted fried food F is transferred to the front fried food input conveyor 2, the fried food transport conveyor 1, and the fried food holding conveyor 3.
After being transported forward in the same way as above,
It falls onto the discharge chute 35 and is discharged.

During the above-mentioned conveyance, the fried foods F
The oil, etc. adheres to the product due to contact with the product. and,
The oil and the like are scraped off by the scraping plate 23 of the scraping member 20 as the conveying roller 14 rotates (see arrow A in FIG. 2). after that,
The oil is discharged through the oil discharge gutter 22. Scraping member 2
The outer circumferential surface of the conveyance roller 14 that has been cleaned in step 0 comes into contact with the fried food F to be conveyed again as it rotates, and removes oil and the like from the fried food F by adhesion. By repeating this process, while the fried food F is being conveyed, oil and the like are removed from the fried food F, that is, deoiled.

Further, oil and the like adhering to the feed belt 28 of the fried food input conveyor 2 are also scraped off by the scraping plate 23 of the scraping member 30, and the feed belt 28 is cleaned. Further, oil and the like adhering to the fried food pressing belt 62 of the fried food pressing conveyor 3 are adsorbed by the wiping cloth 64 of the wiping member 63, and the pressing belt 62 is cleaned.

Sometimes, when the thickness of the fried food F changes, by rotating the handle 51 of the lifting device 4, the lifting member 42 is raised and lowered via a chain transmission mechanism mainly composed of an interlocking chain 52. As a result, the lifting and lowering of the fried food holding conveyor 3 is adjusted to correspond to the thickness of the fried food F. As a result, the opposing distance a of the presser belt 62 with respect to the conveyance roller 14 is
As a result, the pressing force of the presser belt 62 with respect to the thickness of each type of fried food F is adjusted, and the fried food F is conveyed while being properly sandwiched between both conveyors 1 and 3. The oil removal treatment is carried out well.

In addition, when the fried food F has a rollable shape such as a sphere or a rod, the operation lever 96 of the transmission 6 is moved as shown by the two-dot chain line in FIG.
By switching, the sleeve 94 is coupled to the left speed change sprocket 101. Then, since the sprocket 101 has more teeth than the right speed change sprocket 102, the rotation of the front transmission shaft 84 is reduced or reduced to the rear transmission shaft 85 via the transmission mechanism mainly composed of the left transmission chain 103. As a result, the conveyance speed of the fried food holding conveyor 3 is lower than the conveyance speed of the fried food conveyor 1. Therefore, due to the different conveyance speeds, rotational motion is imparted to the fried food F (first
(see arrow B in Fig. 2).
can be conveyed forward while rolling, and oil removal of spherical, rod-shaped, etc. fried foods F can be carried out efficiently.

In addition, in the deoiling machine of this example, since the fried food F is deoiled by inverting it, a good deoiling effect can also be obtained.

In the above embodiment, the fried food conveyors 1 are arranged in parallel in the front and rear, but they may be arranged as one set. Further, the fried food conveyor 1 may be formed by a belt conveyor like the fried food input conveyor 2, and the fried food holding conveyor 3 may be formed by a roller conveyor like the fried food conveyor 1. Also,
Even if the conveyance speed of the fried food holding conveyor 3 is made higher than that of the fried food conveyor 1, the same effect as in the above embodiment can be obtained.

(Effects of the Invention) That is, according to the present invention, the fried food conveyor and the fried food holding conveyor are operated by the drive device, and the fried food is conveyed while being held between both conveyors, and during this conveyance, the fried food is Fried food oil, etc. adheres to the outer periphery of the conveying member of the conveyor, and is scraped off by a scraping member as the conveying member rotates, so a conventional deoiling machine for fried food that adsorbs it to the conveyor belt itself is used. Unlike the above, there is no need for frequent cleaning and replacement of the conveying member, and troublesome maintenance can be eliminated.

In addition, by operating the fried food conveyor and the fried food holding conveyor at different conveying speeds via a transmission device, fried food, especially rod-shaped or spherical fried food, is conveyed while being rolled, compared to conventional conveyors. This has the effect of efficiently removing oil from the fried food.
