6 is provided. Further, the present invention is characterized in that the frying drive means 78 vibrates the frying member 9 at the upper limit position to remove the excess cooking oil 7 adhering to the food.

According to the present invention, as shown in FIGS. 1 to 14, the partition member is moved by moving the rotary storage member in the casing in the circumferential direction by the length of each storage space in a substantially horizontal plane. The food material in each storage space formed by the casing and the casing faces an opening formed at the bottom of the casing. By opening this opening by the shutter means, the food material in the single storage space can be dropped and supplied from the opening.

As shown in FIGS. 1 to 14, the rotary housing has an impeller shape, and its outer shape is substantially cylindrical.

According to the invention, the cooking oil 7 in the storage tank 6 is
Is preferably a temperature predetermined by the temperature adjusting means,
For example, keep it heated to a high temperature of 180 ℃,
From the supply means 5, for example, a frozen or refrigerated food material 4, for example, a block-shaped food material in which potatoes are cut into an elongated rectangular parallelepiped shape, is supplied for each predetermined amount, that is, for each sales amount, The edible oil is dropped and supplied onto the scraping member 9 held at the upper limit position above the oil level. The frozen or refrigerated food material once placed on the frying member in this manner is the frozen or refrigerated food product as the frying member is lowered from above the oil level 62 by the frying drive means 78. The material is gradually or very briefly immersed in the hot cooking oil over time. This causes the food material to be thawed in cooking oil and cooked to a high temperature. In this way, the frozen or chilled food material is not dropped into high-temperature edible oil immediately but is gradually immersed with the passage of time, so that a large amount of edible oil is generated. It can be suppressed as much as possible.

The through hole 73 formed in the frying member is formed smaller than the size of the food material. Therefore, the food material dropped and supplied from the supply means passes through the through hole and the edible oil of high temperature is supplied. There is no fear of being thrown inside. In the food material heated and cooked in the edible oil, the frying member is lifted upward from the oil surface by the action of the frying driving means, and in this state, the dispensing piece 66 of the dispensing member 11 moves in the one direction 12
Then, the food on the frying member is pushed, moved, and discharged, and is conveyed to, for example, the container 14 that stores the food.

In particular, in the present invention, the upper part of the storage tank for storing the edible oil at a high temperature is covered with the cover body 8, and the end of the storage tank on the downstream side in the one direction 12 is set as the discharging member. The closing piece 67 fixed to the payout piece 66 enables opening and closing. As a result, at least the frozen / refrigerated food material is placed on the fried member 9. After that, it is immersed in edible oil at a high temperature, and the upper part of the storage tank is covered with the cover body 8 and the dispensing member 11 during the immersion period. Therefore, it is possible to prevent the oil droplets generated during the immersion of the food material in the edible oil from scattering to the outside,
Further, it is possible to prevent the diffusion of the odor due to the evaporation of the cooking oil.

The food after being dipped in the edible oil is extruded above the oil surface by the dispensing piece 66 as described above to the downstream side of the dispensing in one direction, and at this time, the closing piece 67 moves together with the dispensing piece 66. , There is no hindrance to the transportation of manufactured food,
It can be transported smoothly.

The frozen / refrigerated food material dropped and supplied from the supply means remains mounted on the frying member arranged above the high temperature edible oil. It is also possible to thaw the material and raise the temperature.
It is also possible to further suppress the generation of oil drops and the generation of odor by immersing the food material thus thawed and heated in temperature in the cooking oil.

Furthermore, the food material immersed in the edible oil is lifted up from the edible oil to above the oil level by the frying member,
By maintaining this upper limit position, the edible oil adhering to the food can be returned by flowing down from the through hole of the frying member to the lower storage tank, and wasteful consumption of the edible oil can be prevented.

According to the present invention, when the frozen / refrigerated food material is dropped and fed from the feeding means onto the frying member, the payout driving means moves the payout member to the second position, whereby the payout member 11 is moved. The cover piece 68 has the insertion port formed in the cover body opened. After the frozen / refrigerated food material is placed on the frying member at the upper limit position above the oil surface, the frying member 9 is lowered by the frying drive means 78 and the food material is immersed in the edible oil. At this time, the payout driving means 111 moves the payout member 11 to the second
Return from the position to the first position. Therefore, the input port 64 of the cover body is closed by the cover piece of the dispensing member. Therefore, the space above the storage tank is closed by the cover body and the dispensing member, and the space is made almost airtight so that exhaust and cleaning are possible. Therefore, it is possible to prevent the scattering of oil droplets and the leakage of odor.

According to the present invention, the air containing the oil droplets in the space closed by the cover member above the storage tank and the discharging member is attracted by the attracting fan 92, supplied, and guided to the filter 91. Get burned. Oil drops are captured by this filter. Therefore, the oil droplets are not scattered to the outside, and the diffusion of odor is suppressed.

According to the present invention, after the food material immersed in the edible oil at a high temperature is brought above the oil level by the frying member 9, the frying member is moved above the oil level. For example, it is vibrated up and down. As a result, the edible oil attached to the food is separated from the food, flows downward, and is dropped. The edible oil from the food is returned to the storage tank through the through hole 73 formed in the scraping member as described above. Due to such vibration of the frying member, a large amount of edible oil adhered to the food is not sold and provided as a product, which helps improve the quality of the food.
