A tension spring 78 is interposed between the transmission chain 71 and the tension spring 78, which biases the transmission chain 71 in the tensioning direction.

Next, the drive device 5 for driving the conveyor drive sprocket 33 and the conveyor transmission sprocket 70 will be described with reference to FIG. 11.

A pedestal 80 is installed on the bottom plate 10a of the machine frame 10 so as to be located within the interlocking chain 52 of the lifting device 4.

A drive sprocket 83 is attached to an output shaft 82 of a drive motor 81 installed adjacent to the front of the pedestal 80 .

On the pedestal 80, parallel front and rear transmission shafts 84 and 85 are rotatably supported via bearings 86, respectively.

A driven sprocket 87 is attached to the right end of the front transmission shaft 84.
is installed. An endless drive chain 88 is hung between the driven sprocket 87 and the drive sprocket 83 of the drive motor 81 .

Two transmission sprockets 89 are attached to the left end of the front transmission @84. Each transmission sprocket 8
9 and the front and rear conveyor drive sprockets 33 are each hung with an endless conveyor drive chain 90. Further, a transmission sprocket 91 is attached to the left end of the rear transmission shaft 85, and this transmission sprocket 91 and the conveyor transmission sprocket 70
An endless conveyor driving chain 92 is hung from the conveyor.

A transmission 6, which will be described below, is installed between the two transmission shafts 84 and 85. Approximately at the center of the front transmission shaft 84, left and right sprockets 93 having approximately the same number of teeth are mounted at a predetermined distance and rotatable relative to each other.
A sleeve 94 located between both sprockets 93 is provided so as to be movable in the axial direction via key means (not shown).

An annular groove 95 located approximately at the center of the sleeve 94 engages a bifurcated distal end portion 97 of an L-shaped operating lever 96 . The operating lever 96 has a bent portion attached to the pedestal 80 via a pin 98 so as to be horizontally rotatable;
An operating section 99 at the other end projects to the left of the base 80.

Between the sleeve 94 and each left and right sprocket 93,
Each clutch 100 is provided with dog clutch teeth. Therefore, by rotating the operating lever 96, the sleeve 94 is moved on the transmission shaft 84, and this movement selectively couples the transmission @ 84 and one sprocket 93 via the clutch 100. .

Left and right speed change sprockets 101 and 102 are mounted approximately at the center of the rear transmission shaft 85 at a predetermined interval. The left speed change sprocket 101 is set to have a larger number of teeth than the right speed change sprocket 102. Each speed change sprocket 101, 102 and the transmission shaft 8
An endless transmission chain 103 is attached to each sprocket 93 on the sprocket 4 . Therefore, by moving the sleeve 94 via the operating lever 96, the rotation of the front transmission shaft 84 is controlled by the transmission mechanism mainly consisting of the right transmission chain 103 or by the left transmission chain 103.
The rear transmission shaft 85 is
is transmitted to.

Note that the number of teeth of each sprocket involved in driving each of the conveyors 1.2.3 is selected as appropriate, and normally, the sleeve 94 is connected to the right speed change sprocket 102.
When combined with each conveyor 1, 2.3, each conveyor member, ie, the conveyor roller 14, the feed belt 28
, the conveyance speed (so-called circumferential speed) of the presser belt 62 is set to be approximately the same speed. 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 the front transmission shaft 8
4 is transmitted to the rear transmission shaft 85 at a reduced speed, so that the conveyance speed of the lift presser conveyor 3 is lower than the conveyance speed of the lift conveyor 1. It should be noted that if the sleeve 94 is not connected to the speed change sprocket 101 (or
02), and the transmission chain 103 idles.

In the above-mentioned deoiling method for fried foods, the sleeve 94 of the transmission 6 is now connected to the right speed change sprocket 102, and in this state, when the drive motor 81 is rotated, the rotation is caused by the drive chain The front and rear fried material transport conveyors 1 and fried material input conveyor 2 are operated through a transmission mechanism mainly composed of a transmission mechanism 88, a front transmission @ 84, and a conveyor drive chain 90. Each conveyance member, ie, the conveyance roller 14 and the feed belt 28, is 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 the 8 presser belt 62 of the conveyor 3 is rotated. At this time, the conveyance speed of each conveyor 1, 2.3 is 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 moves the fried food F forward (see Fig. 1). (to the right).

In addition, the fried food F to be put into the oil-removed surface for deep-fried food has just been fried manually or by an automatic frying machine or the like.

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 transferred to the conveyance roller 1 of the fried food conveyor 1.
4 and the presser belt 62 of the fryer presser conveyor 3, the conveyor roller 14 and the presser belt 62
The rotation causes the object to be transported forward. The fried food F sent forward is reversed by passing over the guide plate 34 and falling onto the feed belt 28 of 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 conveyed forward by the front fried food input conveyor 2, the fried food transport conveyor 1, and the fried food holding conveyor 3 in the same manner as described above, and then falls onto the discharge chute 35 and is discharged.

During the above-mentioned conveyance, oil and the like adhere to the outer circumferential surface of each conveyance roller 14 of the fried food conveyor 1 due to contact with the fried food F. The oil and the like are then scraped off by the scraping temporary 23 of the scraping member 20 as the conveyance roller 14 rotates (see arrow A in FIG. 2). Thereafter, the outer peripheral surface of the conveying roller 14 cleaned by the scraping member 20 discharged through the oil IJI gutter 22 becomes old as it rotates, and comes into contact with the fried food being conveyed.
Removes oil etc. from 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. Also,
Oil and the like adhering to the fried food pressing belt 62 of the fried food pressing conveyor 3 are absorbed by the wiping cloth 64 of the wiping member 63, and the surface pressing bells 1 to 62 are cleaned.

Sometimes, when the thickness of the fried food F changes,
By rotating the handle 51 of the lift member 42, the lifting member 42 is raised and lowered via a chain transmission mechanism mainly composed of an interlocking chain 52, thereby raising and lowering the lift presser conveyor 3.
is adjusted up and down to correspond to the thickness of the fried food F. As a result, the opposing gap a of the presser belt 62 with respect to the conveyor roller 14 is increased or decreased, thereby adjusting the pressing force of the presser belt 62 with respect to the thickness of each type of fried food F, and the fried food F is moved between the two conveyors 1.3. Since it is conveyed while being properly clamped, the oil removal process of the fried product F is performed well.

In addition, when the fried food F has a transferable shape such as a sphere or a rod, the operation lever 96 of the transmission 6 is moved to the eleventh position.
By switching as shown by the two-dot chain line in the figure,
A 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 decelerated 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, by imparting rotational motion to the lifted object F by the different conveyance speeds (see arrow B in Fig. 12), the lifted object F can be conveyed forward while rolling. It is possible to efficiently deoil the fried food F.

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. Further, 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 conveyor Fried food oil, etc. adheres to the outer periphery of the conveying member, and is scraped off by the scraping member as the conveying member rotates. There is no need for frequent cleaning or replacement of parts, and troublesome maintenance can be eliminated.

In addition, since the fried material carrying conveyor and the fried material pressing conveyor are spun at different conveying speeds via a transmission device, fried materials, especially rod-shaped or spherical fried materials, are conveyed while being rolled, compared to conventional methods. However, it has the effect of efficiently removing oil from the fried food.
