An embodiment of a continuous frying device of the present invention will be sequentially described below with reference to the drawings.

FIG. 1 is a schematic configuration diagram of a continuous frying device of the present invention. FIG. 2 is a partially enlarged schematic configuration diagram in the vicinity of the terminal end of the frying tank.

The frying tank 9 of the continuous frying device 1 of the present invention is a deep-frying tank, and a carrier 7 for carrying the frying material A while immersing the frying material A in the oil is the same. It is provided from the beginning to the end of the frying tank. The carrier 7 is composed of rotating rollers 2, 3, 4 whose rotation speed can be freely adjusted by, for example, a motor with a continuously variable transmission, and a traveling member 5 mounted on the rollers and rotated by the rollers. It Further, each roller can be attached so as to be movable in the vertical or horizontal direction so that the setting position can be changed. In the roller 4, the traveling member 5 is provided with a frying tank so that the frying product cannot be scraped up while being attached to the protruding piece, and that the frying product can be sequentially pushed up to the discharge conveyor by the protruding piece through the oil. Install it so that it runs diagonally upward toward the rear end of the car. Specifically, the angle b formed by the running member 5 running from the roller 3 provided at the end of the frying tank and the oil level is 3 to.
Install at 20 °.

The running member 5 is a heat-resistant plastic sheet made of Teflon, polyethylene or the like and provided with a large number of small holes of a desired shape (sizes that do not allow the oil frying material to pass through).
Alternatively, a perforated sheet such as a net made of stainless steel or iron can be used. The portion of the traveling member that travels below the oil surface is located below the oil level, and effectively prevents the oil frying material in the oil frying tank from floating above the oil level.

Reference numeral 6 in the drawing denotes a projecting piece which is projected on the outer peripheral surface of the traveling member 5 at an appropriate angle. The deep-frying material A that has flowed into the deep-frying tank is housed in a partitioned space 16 formed by the adjacent protruding piece and the wall surface of the deep-frying tank, and is transported in the oil according to the movement of the traveling member 5. The protruding piece 6 is the tip 1 of the protruding piece.
When the protruding piece 4 runs along the roller 2 on the starting end side of the frying tank, the intersection 17 between the tip 14 of the protruding piece and the oil surface 12 is such that the oil flowing down is the same as the oil surface in the oil frying tank. It is mounted so that it is located on the end side of the frying tank rather than the position 18 which becomes the surface. Further, the distance between the intersection point 17 and the oil level position 18 is set so that the inflowing frying material does not stay on the oil level for a long time. Furthermore, the length of the protruding piece 6 is the same as the tip 1 of the protruding piece.
4 and the bottom of the frying tank 9 are set so that the frying material is not clogged with the frying material and is not deformed or destroyed. The protruding piece 6
Can be used as desired, such as a plate or a plate having holes. The plate-like material is effective when the frying material is pushed up and discharged to a discharge conveyor or the like via the oil surface. On the other hand, when a perforated sheet-like material such as a metal net is used, the frying material adhering to the protruding piece can be effectively peeled off while traveling in the frying tank. Further, an oil sump 19 is provided at the bottom of the oil fryer 9 at the terminal end thereof by opening a metal net, and the oil sump communicates with a discharge pipe 20.

A discharge pipe 20 communicating with the oil sump 19
Is an oil circulation pump 21, an oil circulation amount adjusting valve 2
2. An oil circulation path is formed by connecting the oil strainer 23 and the oil heating heat exchanger 24 to the starting end of the oil fryer 9 and the supply pipe 25 communicating with the lower part of the starting end. In the continuous frying apparatus of the present invention, an oil cooling heat exchanger (not shown) is used for the purpose of promptly cooling the oil used after the frying process is completed and preventing deterioration of the oil. It is also possible to provide it on a route different from. The supply of new oil to the circulation path is performed from a new oil tank 26 through a new oil supply pipe 28 that communicates with a discharge pipe via a regulating valve 27,
The adjustment valve 27 is opened if necessary. 29 in the figure
Is a hood that is provided above the frying tank from the starting end of the primary frying tank to the end of the secondary frying tank, and prevents the heat of oil from being radiated to the outside air and also helps prevent oxidation.

Reference numeral 11 in the drawing denotes a discharge conveyor for discharging the frying material A, which has been frying in the frying tank, to the outside of the frying tank, which also serves as an oil drainer. The present invention is characterized in that the conveyor is installed at a specific position based on the traveling member and the relationship with the angle of the protruding piece provided on the traveling member. That is, the traveling member, as described above, the angle b is 3 to 20 °.
To be installed. In addition, when the traveling member travels from the roller 3 to the roller 4, the projecting piece has an angle c of 45 to 45 formed by the projecting piece or an extension line of the projecting piece and the oil surface.
It is preferable to install it at 90 °. The discharge conveyor 11 of the present invention is installed so as to satisfy the following conditions under the above conditions. First, the lower end is located in oil and the upper end is located outside the oil surface. The lower end portion is preferably located near the bottom of the frying tank so that the frying material does not flow toward the oil sump 19 along the oil flow. Next, the surface 11 and the oil surface 1 of the discharge conveyor
The angle a formed by 2 is set at 3 to 7 ° so that the frying material A can be easily pushed up from the oil surface and the pushed product does not slip into the oil again. Next, at the intersection 13 between the surface portion 11 of the discharge conveyor and the oil surface 12 and at the end portion side of the oil frying tank 9, so that the product that has been lifted up and floated on the oil surface does not stay on the oil surface for a long time. The interval Y between the oil surface 12 and the intersection 15 of the tip 14 of the protruding piece is set so as to satisfy the following equation. (Formula) Y ≧ X / sin b X = Number of frying materials stored in the partitioned space formed by the adjacent protruding piece and wall of frying tank × (speed of traveling member / velocity of discharge conveyor) × frying material Thickness The material of the belt of the discharge conveyor is not particularly limited as long as it has heat resistance such as iron and stainless steel. Further, it is preferable to use a product having an uneven surface or a net so that the fried product does not slip into the oil again and the oil can be removed together.

Next, an example of a frying method using the continuous frying apparatus of the present invention will be described. First, by using an appropriate charging method, the frying tank 9
The frying material A is continuously charged at the beginning of the. High-temperature oil is constantly flowed into the frying tank through the supply pipe 25. The frying raw material that has flowed down to the starting end of the frying tank 9 is sequentially stored in a plurality of units in the partitioned space 16 and is frying while being transported below the oil surface in accordance with the movement of the traveling member. In this case, turbulent flow in the partitioned space 16 can be effectively prevented by making the speed of the traveling member equal to the speed of the oil flowing in the frying tank, which is preferable because the frying material is not damaged. Since new oil can be supplied from the lower part of the starting end of the frying tank as needed, the action of guiding the frying material to the carrier below the oil surface can be expected by the flow rate of the new oil, and the frying material can be sufficiently and evenly distributed. It is possible to swell and dry it, and moreover, it is possible to push away the scraps of the material and the like accumulated on the bottom of the oil fryer toward the oil sump. When the projecting piece is in the form of a porous sheet, the frying material adhering to the projecting piece can be effectively peeled off while traveling in the frying tank. In the frying tank, it is necessary to supply oil as needed and adjust the oil surface and the traveling member so that the portion traveling below the traveling member is always below the oil surface, and constantly frying the frying material in the oil. Is. In some cases, the oil level adjusting valve 30 provided on the way of the discharge valve may be appropriately closed (usually in an open state) to maintain the oil level in the frying tank. The moving speed of the traveling member is appropriately adjusted according to the processing time and the processing amount in the frying tank.

Thus, the frying material transported in the oil while being held below the oil surface to the terminal end of the frying tank, and the frying material floating on the oil surface is pushed by the projecting piece toward the discharge conveyor on the oil surface. Transferred to the conveyor. Then, the oil is drained by the conveyor and discharged outside the frying tank. Then, it is cooled by an appropriate method to obtain a fried product. What is essential here is that the fried product is transferred to the discharge conveyor through the oil so that the fried product is not damaged. In addition, the distance between the tip of the protruding piece and the surface of the discharge conveyor and the installation angle of the discharge conveyor and the traveling member are set to prevent the fried product from staying on the oil for a long time, and to prevent the fried product from being scraped up by the protruding piece. Is to

[0015]

As described above, according to the continuous frying apparatus of the present invention, since the frying products can be transferred to the discharge conveyor without any impact and discharged from the frying tank, they can be uniformly and highly advanced without deformation or damage. It is possible to obtain a deep-fried product that has been deep-fried.

Further, since the distance between the surface of the discharge conveyor and the surface of the traveling member on the oil surface is specified so that the deep-fried product does not stay on the oil surface for a long time until it is discharged to the outside of the oil frying tank, the frying material varies. It is possible to carry out the frying process evenly so that the above does not occur. Furthermore, since the running member is run diagonally upward at a specific angle toward the rear end of the frying tank, it is possible to prevent the frying product from being scraped up while still attached to the protruding piece, and The frying product can be efficiently pushed up to the discharge conveyor through the oil so that the frying product is not destroyed.
