DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyer-type fryer used for cooking and frying foods of relatively different varieties in large restaurants and catering lunch boxes.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional conveyor-type fryer has a transfer conveyer (102) in an oil tank (101) filled with fryer oil (A). The food (B) dropped from the outside of the oil at the upstream end of the transfer conveyor (102) is transferred toward the downstream side of the oil by the transfer conveyor. While being transported, it was lifted out of the oil (A) at the downstream end of the transfer conveyor to complete the fried cooking.

In the conveyor-type fryer, the time required for the food (B) to pass through the oil (A) by the transfer conveyor (102) is the time for frying the food (B).
The time for frying has been adjusted by changing the position where the food (B) is dropped into the transfer conveyor (102) in the upstream and downstream directions. That is, for example, when the size of the food (B) is large and it is desired to fry it for a long time, the food (B) is thrown into the upstream side of the transfer conveyor (102) to lengthen the time for the food (B) to pass through the oil. When it is desired to shorten the frying time, the frying time is adjusted by shortening the time of feeding the oil downstream and passing through the oil.

[0004]

By the way, foodstuff (B)
Some foods (B) have a property of floating when they are lifted to some extent. Even if the foods (B) are to be transported by the transport conveyor (102), they float away from the conveyor (102) on the way, and In some cases, transfer cannot be performed. For this reason, generally, in the conveyor-type fryer, a holding conveyor (103) for transferring the floating food (B) while maintaining it in the oil is provided in parallel at a certain interval above the transfer conveyor. Have been.

However, in order to ensure that the food (B) floating from the transfer conveyor (102) is maintained in the oil,
Since it is necessary to cover the widest possible portion of the transfer conveyor (102) with the pressing conveyor (103), the range for dropping the food (B) for adjusting the frying time is narrowed, and a single fryer can handle many types of food. It was difficult to respond to food (B).

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems, and has a wide range of adjustment of the time for frying ingredients, and a conveyer-type fry which can flexibly cope with various kinds of ingredients. The task is to provide machines.

Can flexibly respond to the size of

The foodstuff (B) dropped into the oil falls on each of the transfer conveyors (20) and (21), is sent on the conveyor to the downstream side in the oil, and is conveyed to each conveyor (2).
0) It is carried out of the oil (A) through the downstream inclined portion of (21).

The time during which the food (B) stays in the oil, that is, the time during which the food (B) is fried, is determined by the transfer speed of each of the transfer conveyors (20) and (21) and the position where the food (B) is dropped. Is, in this embodiment,
Since the two sets of conveyors are set at different transfer speeds, for example, on the side of the small conveyor (20) where the transfer speed is set to be slow, frying is performed by selecting the position (C) into which the food (B) is dropped. The time can be adjusted in the region where the time is long. On the other hand, on the side of the large conveyor (21) where the transfer speed is set to be high, by selecting the position (C) where the food (B) is dropped, the time can be adjusted in an area where the frying time is relatively short. . In other words, two types of adjustment regions for the frying time can be set by one frying machine. The frying time can be continuously and widely adjusted by overlapping a part of the adjustment area.

Some foodstuffs float up while being transported in the oil, but are transported while being prevented from being lifted up by being held down by the holding conveyors (30, 31). In addition, the corresponding transfer conveyors (20) and (21) and the holding conveyors (30) and (31).
Since they are driven in an interlocked state by the drive belts (52) and (53), the transport speeds are the same, and the food (B) that floats in the oil (A) and the food (B) that does not float in the oil (A).
There is no difference in frying time between the two.

As described above, the foodstuff (B) which has been passed through the oil for a predetermined time and fried is transferred to the transfer conveyor (20).
It is sequentially dropped from the downstream end of (21) to the outside of the oil tank (1), and is slid down to a predetermined position by the chute (13).

The present invention is not limited to the above embodiment. For example, the number of transfer conveyors provided in one oil tank (1) is not limited to two but may be three or more. Also, the type of belt used for each conveyor is not particularly limited, and any type and combination thereof can be selected. For example, as shown in FIG. 4, one transfer conveyor (20) is constituted by a mesh belt, and the other transfer conveyor (21) is formed by a plurality of elongated strip-shaped metal plates in parallel in the width direction. It is good also as what comprises a belt arranged side by side and each connected in a bendable manner. By making the type of the conveyor belt different in this way, for example, foodstuffs whose surface is hard to form such as a croquette or a cutlet having a dry surface are transported by a conveyor (20) made of a net-like belt, and tempura and the like. As described above, a food material which is easily formed due to its wet surface can be transported by a conveyor (21) comprising a strip-shaped plate connecting belt, and can flexibly cope with the characteristics of the food material. In FIG. 4, the same reference numerals are given to the same components as those shown in FIGS. 1 to 3, and the description thereof will be omitted.

Also, when the food (B) is dropped, it cannot be placed on the target conveyor, and the food (B) being transferred is not transferred from one conveyor to the other conveyor. A partition plate or the like may be provided to partition the space.
