Description

  The present invention relates to a blower homogenizer and an object powder processing system, and more particularly to a technique for removing excess powder from an object, such as removal of excess powder in a fried food manufacturing process. .

The production of chicken nuggets and other fried foods involves a process in which a semi-finished product such as putty is coated with a powder such as a batter powder and then fried with a fryer.
FIG. 6 is an explanatory view showing a main part of a conventional fried food production process. As shown in the figure, in a conventional fried food production line, when a semi-finished product M enters a powder coating processing device 61 such as a blitter machine (a device that performs a process of coating a semi-finished product with a blotter powder) The powder P is applied (powdering), resulting in a semi-finished product PM in which the powder P is excessively applied. On the downstream side, surplus powder P on the semi-finished product PM is blown off by the air blown from the fan 62, and the blown off powder P is sucked and collected in the dust collector 63, and the surplus powder is removed. As a result, a semi-finished product QM in a state where the powder is appropriately coated is obtained, and the semi-finished product QM is subjected to the oil frying treatment in the fryer 64 to obtain a fried food. Further, the powder P collected in the dust collector 63 is returned to the powder dusting processing device 61 and used for the next coating process.

  Conventionally, many technical proposals have been made regarding fried food manufacturing technology. For example, in Patent Document 1 listed below, in the process of manufacturing meatballs and other fried foods, the semi-finished products are prevented from sticking to each other after being treated with batter liquid, bread crumbs, etc. An apparatus having a structure in which a gate composed of a gate-shaped support frame and a fence-shaped support body is installed after a batter liquid flow lower portion where sticking easily occurs is disclosed.

Japanese Utility Model Publication No. 60-85192 "Processed food sticking prevention device"

Now, the conventional fried food production line shown in FIG. 6 has the following problems.
a) Although the blowing direction by the fan 62 is restricted by a temporary throttle structure, the directivity is weak and the blowing is uneven. Therefore, the scattering direction of the powder P blown off from the semi-finished product PM is multi-directional and will be described later. It leads to leakage through the gaps between people.
b) Since the conveying path 65 is not a sealed space, the surplus powder P blown off by the fan 62 is not completely sucked by the suction port 66 but leaks from the gaps between the people and is scattered around. Resulting in. The amount of scattering is not small.

c) The scattered powder cannot be returned to the powder coating processing device 61 and used for the next processing, and the powder, which is a food sub-material, is wasted, and a corresponding cost is required.
d) Due to the scattered powder, not only the periphery of the powder coating apparatus 61 but also the floor and walls of the line installation space are contaminated, and the labor required for cleaning is great.
e) The scattered powder adheres to the operator's face and clothing, stress is increased, and the working environment is deteriorated.
f) In the conventional powder removal / recovery system, it is essential to install a dust collector. However, it requires maintenance such as assembly and cleaning of the dust collector and filter cleaning during line operation. It is.

  In the field of manufacturing fried foods, there is a need to solve these problems. In addition, these problems are not limited to the field of frying food manufacturing, but are common to all manufacturing technical fields that require a process of removing excess powder from an object.

It is.

  As a result of studying the above problems, the inventors of the present application have found that the configuration of the apparatus can perform uniform air blowing in which the direction and the air volume are uniform instead of the conventional fan that disperses the powder to the people because the air blowing direction is wide. In addition, the inventors have conceived a cover structure for suppressing the scattering of the powder, and have completed the present invention based on these. That is, the inventions claimed or at least disclosed in the present application as means for solving the above problems are as follows.

Hereinafter, the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cross-sectional explanatory view showing a basic configuration of a blower homogenizer according to the present invention. 2 and FIG. 2-2 are explanatory views sequentially showing the operation of the air blow uniformizing apparatus shown in FIG. As shown in these figures, the air blow uniformizing device 10 includes an air supply unit 1 for introducing air A for air from the outside, an air flow control structure 2 for temporarily blocking the introduced air A and changing the flow direction, and The main configuration is that the housing 4 is provided with the blower 3 that discharges the air A whose flow direction has been changed by the airflow control structure 2.

  The airflow control structure 2 can be formed as a structure provided with a partition plate 5 that partitions a part of the internal space of the housing 4. That is, the entire internal structure of the housing 4 in which the internal space is partitioned by the partition plate 5 is the airflow control structure 2. In the drawings used for the following description, the partition plate 5 itself, which is an important element for forming the airflow control structure 2, may be referred to as “airflow control structure 5 (2)”.

  With this configuration, according to the air blow uniformizing apparatus 10 of the present invention, the air A for air blowing from the outside is introduced into the air supply unit 1 and enters the housing 4, and the introduced air A is temporarily transmitted by the air flow control structure 2. Air A whose flow direction has been changed by the weir is changed and the flow direction has been changed by the airflow control structure 2 is discharged from the blower 3.

  That is, in this air blow uniformizing device 10, the air A introduced from the air supply unit 1 is not directly sent from the air blowing unit 3 but is temporarily blocked by the air flow control structure 2 and further guided along a certain flow direction. By doing so, the flow direction and flow rate of the air A are adjusted to be constant, and the air flow is made uniform in this way, and is discharged from the blower unit 3 as air A for blowing.

  As described above, the airflow control structure 2 can be formed by the partition plate 5 that partitions a part of the internal space of the housing 4. The specific structure and specifications of the partition plate 5 are not particularly limited as long as the structure has a function of once blocking the introduced air A in the housing 4 and then changing the flow direction. However, for convenience, as shown in each figure, a single plate that is provided substantially parallel to the direction of the air A introduced from the air supply unit 1 and divides the housing 4 vertically except for a part thereof. A shaped body can be used as the partition plate 5. The partition plate 5 having such a simple structure can provide a sufficient air blowing uniform effect.

  That is, in this case, the partition plate 5, the upper space 4a and the lower space 4b partitioned by the partition plate 5, and the communication portion 4c provided on the air supply unit 1 side and communicating with the two spaces 4a and 4b communicate with each other. The control structure 2 is formed, and it is the partition plate 5 that enables this formation. Next, the airflow control action for the air A by the airflow control structure 2 will be described.

  The air A introduced from the air supply unit 1 first travels straight in the upper space 4a, collides with the end portion 4ax (inner wall of the housing 4) and is compressed (FIG. 2), and flows back through the upper space 4a. The communication portion 4c is reached, receives an inductive action by the communication portion 4c, and proceeds to the lower space 4b instead of the air supply portion 1 into which the subsequent air A is introduced, and then passes through the lower space 4b. It goes straight ahead and reaches the blower 3 and is sent out from the blower 3 (FIG. 2-2). That is, the introduced air A circulates through the route of the terminal space 4a of the upper space 4a—the communication portion 4c—the lower space 4b—the air blowing portion 3 that is the terminal portion thereof.

  Since compressed air is preferably used as the air A to be introduced, the material, physical properties, size, thickness, and other specifications of the partition plate 5 are as long as they can withstand the pressure for a long time. It is not limited. However, it is desirable that the air supply unit 1, the partition plate 5, and the air blowing unit 3 are provided in the arrangement relationship illustrated. That is, the air supply unit 1 is at the upper upstream end of the housing 4, the air blowing unit 3 is at the downstream lower end of the housing 4, and the partition plate in the housing 4 so that the airflow path described above is formed. 5 is a structure arrange | positioned in the height position between the air supply part 1 and the ventilation part 3, respectively.

  Further, as shown in the figure, the air blowing unit 3 of the air blowing uniformizing device 10 may be configured such that air is ejected at a corner of the housing 4 at a downward angle from the bottom surface of the housing 4. it can. The present blower homogenizer 10 aims to blow off and remove excess powder from an object coated with powder, but efficiently blows air away from the object in an oblique direction. It is for performing. In addition, when the object is continuously conveyed in a substantially horizontal direction, the blowing and removing action is performed in a certain direction to limit the powder dissipation and the scattering direction.

  The effect mentioned above is acquired by making the ventilation part 3 into the structure which faced diagonally downward at an appropriate angle. The angle setting can be arbitrarily designed. Moreover, as shown in FIG. 3 to be described later, the blower section 3 (“33” in FIG. 3) can have a single eaves-like structure. As a result, the sheet-shaped air blowing having the same width as the width of the housing 4 (“34” in FIG. 3) of the air blowing uniformizing apparatus 10 (“310” in FIG. 3) is applied to the object. When covering the conveyance path width of the object to be sprayed and conveyed, uniform air can be blown over the entire object conveyance path.

  FIG. 3 is an explanatory perspective view showing an embodiment of the blower equalizing apparatus of the present invention. As shown in the figure, the blower equalizing device 310 can be configured to include a plurality of air supply units 31. Although the figure shows an example where eight places are provided, the number of installations is not limited. Such a configuration of simultaneous air supply at a plurality of locations makes it possible to introduce air for blowing into the casing 34 having a wide width evenly, and the introduced air is subjected to airflow control as shown in FIG. The sheet is integrated (equalized), passed through the lower space, and sent out from the bowl-shaped air blowing section 33 as an integrated sheet-like air.

  The blower homogenizer of the present invention can be used without particular limitation in the technical and industrial fields where uniform and uniform blow is desired. In particular, as described above, it is most suitable for removing excess powder from an object coated with powder, such as in food processing industries such as fried food manufacturing.

  FIG. 4 is a conceptual explanatory diagram showing the basic configuration of the object powder processing system of the present invention. As shown in the figure, the object powder processing system 450 is a system that performs a process of applying powder to an object and removes and collects surplus powder. The main configuration is to include the compressed air supply device 400 that supplies air for blowing to the blower uniformizing device 410.

  With this configuration, the object powder processing system 450 performs a process of applying powder to the object, while the air for blowing is supplied from the compressed air supply device 400 to the blowing uniformizing device 410 to uniformize the blowing. In the apparatus 410, the supplied air is subjected to airflow control to blow air to the object, surplus powder on the object is blown off by air blow and removed, and the removed surplus powder is collected. A specific embodiment of the system of the present invention will be described.

  FIG. 5 is an explanatory view showing a main part of an example of a fried food manufacturing process using the object powder processing system of the present invention. This example is an example related to a production line for fried foods such as chicken nuggets, and the powder to be applied, removed, and recovered is assumed to be a blitter powder, but the present invention is not limited to these. .

  The manufacturing process will be described with reference to the drawings. When the semi-finished product M is conveyed by the conveyance path 55 such as a net conveyor and enters the region of the powder coating processing device 51 such as a blitter machine, the powder P such as the blotter powder is applied to the semi-finished product M to obtain the powder. Becomes a semi-finished product PM in a state of being overcoated. On the other hand, compressed air (pressure air) from the compressed air supply device 500 is introduced into the blower uniformizing device 510, and uniformized and uniform blow is performed on the semi-finished product PM to which excess powder is adhered. The

  The air is blown in the opposite direction of the line traveling direction, that is, facing the semi-finished product PM coming toward it. Therefore, powder scattering in the traveling direction is unlikely to occur. In addition, since the powder coating processing device 51 has a sealing structure for preventing the scattering of the powder P generated by the blower uniformizing device 510 from leaking outside, the outside of the powder P is provided in the region of the powder coating processing device 51. Scattering is effectively prevented. In the drawing, the cover of the outlet portion indicated by reference numeral 530C and the portion covering the conveyance path 55 indicated by reference numeral 530A have a sealed structure.

  The powder P blown off from the semi-finished product PM by the air blowing from the air blowing uniformizing device 510 is effectively prevented from being scattered to the outside by the sealing structure 530C and the like, falls in the powder coating processing device 51, and is stored. Is done. The stored powder P is collected and can be used for the next coating process, and is not wasted. On the other hand, the semi-finished product QM in which the powder is appropriately coated falls on the fryer at the end of the conveyance path 55 and is subjected to oil frying treatment to complete the fried food.

  In the prior art, it was necessary to install dust collecting means (dust collector 63) (see FIG. 6). However, in the object powder processing system 550 of the present invention, surplus powder removed from the object (semi-finished product) PM. There is no need to provide expensive dust collecting means (dust collector) for sucking and collecting P. A fan is also unnecessary. By eliminating these, the labor and time required for assembly and cleaning of the dust collector and maintenance during work are no longer required, the line installation location is clean, the passages are sufficiently secured, and accidents involving falls are prevented. became. First of all, the powder blowing / scattering prevention effect of the inventive air blower homogenizer and the object processing system, the effect of reducing the cleaning labor and time, the improvement of the working environment, the effect of reducing the waste of auxiliary materials such as batter powder Soon, it was confirmed that the overall cost reduction effect was significant.

  According to the air blow uniformizing apparatus and the object powder processing system of the present invention, it is possible to blow air evenly and effectively prevent the powder from being scattered, thereby greatly reducing the waste of the powder. The recovery rate can be increased to reduce costs, leading to reduced labor and improved work environment. Therefore, in the field of manufacturing fried foods, it is a device with high industrial applicability in all manufacturing technology fields where it is necessary to apply powder to objects and remove and recover the surplus, and all related fields. is there.
