Description

[Detailed Description of the Invention] <Industrial Application Field> The disclosed technology applies flour, bread crumbs, rice flour, etc. to the surface of foods such as meat of aquatic animals and agricultural products that have been cut into desired shapes such as squares and strips. It belongs to the field of dusting technology that evenly coats grain flour.

<Summary of the gist> The invention of this application is a method for continuously conveying food materials such as fish and shellfish, meat such as meat, vegetables, etc., and grain flour, which have been pre-cut into a desired shape such as a square shape or a rectangular shape. This invention relates to an automatic flouring method for uniformly coating the surface of foods with grain flour, and its direct use. Both are transferred and rotated in a cylindrical drum at the flap part, avoiding twisting and rounding, and scooping up, reversing, etc.
A continuous powder for food that uses splashing to apply dust while stirring, sieves the powdered food and excess powder, and returns the excess powder to the dusting section for recycling. This invention relates to an attachment method and apparatus.

<Prior Art> As is well known, in the food industry, instant foods, frozen foods, and the like are widely distributed as simple foods and major products in the distribution market.

Among these simple foods, fried foods are widely used in frozen form because of their long shelf life, high nutritional value, and good taste.

Such fried foods are finally frozen and undergo a so-called buttering or blending process in which the raw food is coated with grain flour such as wheat flour, bread crumbs, or rice flour at the manufacturing stage before being packaged.

However, if buttering is applied directly to the fried food material in the buttering process, water may ooze out of the food material, making it difficult for the material to adhere, or the buttering may become thin.
There is a problem with oil splashing water during frying, causing the batter to peel off.

To deal with this, it is common to perform a so-called dusting process in which flour or the like is sprinkled before the buttering process.

<Problems to be Solved by the Invention> Conventionally, the work of the seeding process was generally done manually, and the frying material food was added to the flour to be mixed with flour, and both were manually separated. Methods such as stirring and covering were used.

In such work, firstly, manual work is carried out in floating dust such as grain flour, which is an unfavorable working environment.Also, manual labor causes significant fatigue in the wrists, etc., making it difficult to perform the work. There is a problem in that efficiency is lowered, and as a result, there is a risk that the fried food material is unevenly coated with flour, resulting in poor product yield and reduced product quality.

Furthermore, since the process is done manually, there is also the negative aspect of food hygiene issues that cannot be ignored.

To deal with this, automatic flouring methods using mechanical means have been devised; for example, as shown in Japanese Patent Publication No. 53-9361, flouring flour is uniformly spread on a belt conveyor. While transporting the fried food, some measures have been taken to sprinkle the flour onto the fried food or press it from above. There is also the disadvantage that the adhesion to the food surface is weak, and the flour peels off from the fried food material by the time of battering or pre-frying. There is a method of making the flour adhere firmly by dropping the raw food material, but this method has the disadvantage that the powder only adheres to one surface of the falling fried food material and is difficult to adhere to all of the surfaces. .

Similarly, in the breading process of the conventional blending process, it was difficult for the bread crumbs to adhere uniformly to the food, and in particular, the adhesion of the bread crumbs to the edges of the food was insufficient.

Therefore, as a food dusting device, for example,
There is an invention disclosed in JP-A No. 51-112580, in which the seeding device not only dusts the food, but also brings the food into face-to-face contact with a spiral screw fin during the dusting process. It has a process of rolling and forming it into a spherical shape through rolling, and as clearly stated in the publication of the prior invention, the shape and powder of confectionery etc. are changed before being supplied to the powdering device. The shape that is discharged after attachment is different,
A predetermined shaping action is also carried out during the dusting process, and in such well-known dusting equipment, a spiral fin inside the equipment forcibly rolls up the food to be dusted, making it into a spherical shape. It has a positive effect.

Applying such a powdering device to raw materials for fried foods such as fish and shellfish such as fried foods, meat such as livestock meat, and vegetables, it is important to apply the powdering device to raw materials for fried foods such as fish and shellfish such as fried foods, meat such as livestock, and vegetables. If the food material is rolled up after dusting or is twisted, the shape may change between the feeding condition before the dusting process and the feeding condition to the next stage after dusting, and the food may be different from the initial purpose. However, this had the disadvantage of not being viable as a product.

Therefore, such a dusting device has the disadvantage that it cannot be used for dusting while always maintaining the shape of the initially formed food material.

<Purpose of the Invention> The purpose of the invention of this application is to provide a powder coating method for fried food materials in the flour coating step in the manufacturing process of fried food products, which is particularly excellent among simple foods having various advantages based on the above-mentioned prior art. The technical challenge is to solve the problem of insufficient adhesion of grain flour such as flour and bread crumbs, and to ensure the adhesion of grain flour to fried food materials, while maintaining the initial shape of the fried food materials. It ensures reliable adhesion to surfaces, eliminates manual labor and maintains a sufficiently sanitary work environment, significantly increases product yield and precision, and economically reduces the amount of flour used. It is an object of the present invention to provide an excellent continuous dusting method and apparatus for food products that can benefit the field of application of processing technology in the food industry.

<Means/effects for solving the problems> In order to solve the above-mentioned problems, the structure of the invention of this application, which is based on the above-mentioned claims, is to solve the above-mentioned problems. To obtain a fried food, the fried material food, which has been formed into a predetermined shape such as a square shape or a rectangular shape, and a surplus amount of flour are continuously fed to the covering section of a continuous dusting device. A plurality of buttful rods etc. fixed inside the drum perform the scooping, inversion and flipping actions in a rotating state while avoiding twisting and rounding, thereby causing the fried food material and flour to rise and fall within the drum. The flour is repeatedly subjected to the splashing action, etc., and the flour is evenly thrown onto the entire surface of each fried food material, ensuring that it adheres, and is completely covered with flour. The surplus flour is sieved, and while maintaining the predetermined shape, the former goes through the above-mentioned dusting process and is sent to the next processing step.
The latter is returned to the glazing section and is provided with a technical measure for the next glazing operation.

<Example> Next, an example of the invention of this application will be described below with reference to the drawings.

The supply section 4 has a frame 7' on which the rollers 3 and 3 are erected, and a hopper 26 for frying material food and a hopper 27 for flour such as flour or bread crumbs as flour are provided on the upper part of the frame 7'. A stirring device 28, 28 is provided in each case to prevent bridging.

A shared belt conveyor 29 is provided below the hopper 26 and the flour hopper 27, and its tip is exposed to the inside of the return drum 18 and also to the inside of the drum 9. .

Therefore, the return fin 1 of the return drum 18
Returned flour, which will be described later, falling from the drums 9, 19, . . . is returned into the drum 9 by a belt conveyor 29.

Note that 30 is a drive motor, which is used to operate the belt conveyor 29.

In addition, a sieve part 1 is attached to the frame 7 at the bottom of the drum 9.
A return belt conveyor 31 is provided from the tip of the drum 6 to the return drum 18.

Therefore, as mentioned above, the conveyance section 6, the main body section 5, and the supply section 4 are each separate parts, and by combining them, the three can be combined into a unit plant as shown in FIG. Moreover, by easily disassociating from each other, cleaning and maintenance/inspection work can be performed.

In the above-mentioned continuous dusting device 1, as shown in Fig. 1, the conveying section 6, main body section 5, and supply section 4 are assembled and set in a unit plant, and the fried food is coated with wheat flour. Although not shown for the hopper 26 of the supply section 4,
For example, frying ingredients such as fish toppings, meat, vegetables, etc., which have been cut and formed into predetermined shapes and sizes such as squares and strips, may be fed into the hopper 27, and grain flour such as wheat flour and bread crumbs may be fed into the hopper 27. The mixture is stirred to prevent bridging, and the drive device 30 is operated to feed the mixture into the drum 9 of the covering section 5 via the belt conveyor 29 at the bottom of each.

In addition, in the covering section 5, a drum 9 is rotated via a belt 12 and pulleys 13 and 14 via a motor 11, and each bar 15 of the sieving section 16,
15... are integrally rotated, and furthermore, the return drum 18
are rotated together with the scooping fins 19, 19, . . .

Therefore, the frying material food and the flour are both supplied into the drum 9 via the belt conveyor 29 of the supply section 4, and the buttful rod 25 of the covering tool 20 is fixed in advance by pressing on the inner surface of the drum 9, as described above. ，
While being reversed by the rotational action of the rotation of the drum 9 of 25..., it receives a scooping action and a flipping action, and is fed forward using the inclination of the drum 9.

During this time, the buttful rods 25, 25... make dot-like or linear contact with the food material, and there is no surface contact with the screw fins, etc. as in the conventional method, so deformations such as twisting and rounding will not occur. Does not occur.

Therefore, the fried food material that has been formed into a predetermined shape such as a rectangular shape or a rectangular shape by these actions maintains the formed shape and is coated with flour over its entire surface and passed through the next sieving section 16. will be sent to.

Due to the above-mentioned covering action by the buttful rods 25, 25, etc., even if the fried food material is preformed into a rectangular shape as described above, the covering action is completed by bending or rounding. There is nothing that would not be done, and it is also subjected to a kind of alignment action, and a complete covering action is performed.

The amount of flour supplied by the hopper 27 and others to the frying material food to the drum 9 is set to be a surplus based on theory and experimental data.

From this point of view as well, the flour is more completely coated on the fried food material in the coating portion 5.

The powdered food and surplus flour discharged from the drum 9 are then integrated with the drum 9 into the straight-extending bars 15, 15, . The powdered food is conveyed while being rotated inside the bars 15, 15, and subjected to a sieving action, and the powdered food maintains its formed shape from its tip to the conveying section 6, which is the next processing step. In the sieving process, surplus flour is fed through the hesiute 17, and the surplus flour is passed through the bar 15,1.
5... falls onto the return conveyor 31 and is transported back into the return drum 18.

Depending on the design, although not shown, inclined chute may be provided on both sides of the return conveyor 31 to receive excess flour falling from the bars 15, 15, . . . .

The surplus flour returned to the return drum 18 is scooped up and raised by the return fins 19, 19, which rotate within the return drum 18,
It falls onto the belt conveyor 29 from above and is fed into the drum 9 again together with the fried food material and flour supplied from the hoppers 26 and 27.

By following such a process, the operation of dusting the supplied fried food with flour is performed fully automatically, eliminating the need for manual labor at all, and also keeping the surrounding working environment clean.

It should be noted that the embodiment of the invention of this application is, of course, not limited to the above-mentioned embodiment. For example, the structure and attachment of the buttful rod 25 is not limited to this embodiment, and various means may be taken. It is.

In addition, in the sieving section, a cover is provided for the return belt conveyor 31 around the bars 15, 15... to prevent dust, and the return belt conveyor 31 is provided with a cover for detecting the return flour as appropriate. Various methods can be adopted, such as providing a sensor to detect the amount of returned flour and automatically controlling the amount of flour supplied to the hopper 27.

<Effects of the Invention> As described above, according to the invention of this application, the work of covering food materials such as frozen fried foods with grain flour such as wheat flour or bread crumbs is fully automatically performed from supply to discharge to the next step. , does not require any manual labor, and is highly efficient because it is carried out in a nearly sealed state, and has the excellent effect of keeping the working environment sanitary and reducing unnecessary power.
Therefore, the overall operation of the frying process can be carried out efficiently.

Therefore, in the covering process, surplus flour is returned to the return drum and immediately reused and recycled together with the food material fed into the drum, so the return process is short and unsanitary problems are avoided. This provides an excellent effect in that there is no risk of contamination with dust or the like.

By feeding back the surplus flour to the dusting section in this way, it is possible to anticipate and supply that amount of surplus flour to the supply section in advance.
The flour cannot be sufficiently coated on the food material in the drum of the covering section, resulting in insufficient coating of the food product, or peeling during the subsequent frying process. There is also an excellent effect of sufficiently improving product accuracy.

Further, even if surplus flour is generated, it is recycled to the covering section, so there is an advantage that nothing is wasted.

In the covering section, the food material and the flour are rotated by a buckle rod and the flour is applied to the surface of the food material completely by scooping, flipping, and turning the food. Not only can it be sprinkled, but the Buttsuful stick and the raw food are in point-like or linear contact with each other, and do not touch each other.
Therefore, it is possible to avoid twisting, rounding, etc. of the raw food material, thereby preventing the initial formed shape from being damaged, and to have the excellent effect of allowing grain flour to adhere to the entire surface of the fried food material with a high yield. be done.

Further, in the sifting section, there is an advantage that unnecessary use of flour is eliminated by sifting the floured food and excess flour.

In addition, in the continuous dusting device, by providing a hopper for the food material and a hopper for the flour in the supply section, the first-stage covering action can be performed in advance even during conveyance to the covering section by the conveyor. In addition, unlike spiral fins, the multiple buttful rods installed in the drum in the covering section allow food materials to be fed without being twisted or rolled up. This has the effect of performing a covering action while maintaining the formed state of the raw material food, which separates the excess flour in the rear sieving section from the covered food material that remains in its initial formed state. Therefore, an excellent effect can be achieved in that the raw food material can be reliably coated with flour on all surfaces and discharged while maintaining its initially formed shape from supply to discharge.

Further, since excess flour can be returned from the sieving section to the return drum at the front of the drum, an excellent effect is achieved in that the flour can be effectively utilized in a closed cycle.
