Note that the midpoint between the left and right sides is located at approximately the same position as the oil level Fa. Therefore, the first pressing frame 44 and the second pressing frame 45 are operated by respective operating mechanisms 56 and 5 such that they have an opposite motion relationship (a half-cycle phase relationship).
6 is set. Due to the mutual movement of these pressing frames 44 and 45, the material S transferred by the impeller 41 is transferred while being pushed down in an arcuate and wavy manner in a counterclockwise direction (counterclockwise in FIG. 1). Ru. A third guide plate 76 is installed from the right end of the bracket 25 to the rear side plate of the pot body 11 so as to surround approximately the left half circumference of the saucer plate 43 in an arc shape.

rotated to By the rotation of the impellers 77 to 77, the material S transferred by the presser transfer device 42 is transferred to the right.

A take-out conveyor 79 is provided in an inclined manner at the take-out port 13 of the pot body 11. This unloading conveyor 79
In this example, a net belt 81 made of a mesh of chain material is stretched around rollers 80, 80 which are rotatably installed between the front side plate and the rear side plate of the outlet 13. 81 is rotated clockwise (clockwise in FIG. 2) via rollers 80, 80 by a suitable drive device (not shown). This conveyor 79 receives the material S transferred by impellers 77, 77, lifts it diagonally upward to the right from inside the cooking oil F, and carries it out. ). Note that this net belt 81 is connected to the intermediate conveyor 3 described above.
Similarly to the mesh belt 39 in No. 4, the plates 81a to 81
a are arranged at approximately equal intervals.

Next, a case where fried foods are fried using the above-described deep-frying machine will be described. First, the cooking oil F is stored in the pot body 11, and the heating devices 14, 14 are ignited to raise the temperature of the cooking oil F to an appropriate temperature (frying temperature), and each drive device is started. Therefore, the raw material S, which has been previously molded into a predetermined shape by a molding machine, is put into the cooking oil F on the first rotary plate 15. The loaded material S initially sinks into the cooking oil F due to its own weight, and is sequentially transferred by the first rotary plate 15. When this transfer has passed approximately half a turn, the material S slides onto the second rotary plate 16 under the influence of its centrifugal force and the flow of the edible oil F. At this time, the left side support piece 24 prevents the material S from being returned to the input port 12. Moreover, the material S that has been floating in the cooking oil F or floating on the oil surface Fa due to frying is transferred to the second rotary plate 16 side by the first transfer conveyor 23. The material S transferred by the second rotary plate 16 is fried to an appropriate degree and floats in the edible oil F or floats on the oil surface Fa, and is then transported by the second rotary plate 16. It moves in an arc shape due to the flow of oil Fa. This material S is linearly transferred to the right by the second transfer conveyor 31, then pulled up from the cooking oil Fa by the intermediate conveyor 34, and further horizontally transferred to the right. The raw material S hits the guide plate 40 at the end of the conveyor 33 and is guided in a reverse direction, and is dropped into the cooking oil F. This material S is impeller 4
1 to 41, and then transferred in an arc shape while being pushed down in a wavy manner by the mutual movement of both pressing frames 44, 45 of the presser transfer device 42. The material S thus transferred is transferred to the impeller 7.
The fried tofu is completed by the time the tofu is transferred to the right by 7 to 77, and then lifted out of the edible oil F by a carry-out conveyor 79 and carried out to a storage container.

In addition, the following can be considered as other technical means than the above embodiment.

(a) Three or more rotary plates 15, 16 should be provided.

(b) Eliminate the saucer plate 43.

(c) Each mesh belt 28 of the transfer conveyor 23, 31,
33, a plate that hangs down due to its own weight is provided in place of the hanging nets 28a and 33a.

(d) The reference height of each pressing frame 44, 45 of the presser transfer device 42 can be adjusted.

(e) The number of pressing frames 44 and 45 of the presser transfer device 42 is reduced to one.

(Effects of the Invention) In other words, since the present invention has the above-described configuration, it is possible to fry the ingredients by moving them in a meandering manner within the pot, and it is possible to fry the ingredients in a meandering manner. The necessary time can be secured by setting the frying distance as long as possible in a narrow installation space, thereby making it possible to downsize the frying machine.

In particular, the present invention is one in which a plurality of rotary plates are arranged adjacent to each other, the mutually adjacent rotary plates are rotated in opposite directions, and a portion of the rotary plates are closely overlapped with each other. By rotating the rotary plates in opposite directions, the material to be fried can be transported in a meandering manner, and the transport distance to the intermediate conveyor can be made as long as possible, resulting in good deep-frying.

In addition, the transfer start end of the presser frame of the presser transfer device is
Since it is disposed below the transfer end portion of the intermediate conveyor, the space for arranging the intermediate conveyor and presser transfer device is reduced as much as possible, which has the effect of further downsizing the oil pump.
