Description

Description: BACKGROUND OF THE INVENTION The present invention relates to a process for exposing a food or the like in a process immediately before packaging to a flame for a very short time to incinerate flammable foreign substances mixed in the food or the like. In addition, the present invention relates to an apparatus for removing contaminants, such as foods, for preventing foreign substances from being wrapped together with foods.

2. Description of the Related Art Generally, foods and the like (including small mechanical parts and the like other than foods, the same applies hereinafter) completed through a predetermined production process are usually packaged according to the foods and the like and distributed to the market.

Therefore, if foreign matter is mixed in the package of the food or the like packaged in this way, it often results in a loss of the credibility of producers regarding product management. The problem is that the food industry pays great attention to easily lose the business credibility of producers who have formed over a long period of time.

For example, in the case of so-called dry set products in which several types of food are mixed and packaged in an appropriate amount, the packaging process must rely on humans, and even if attention is paid,
A situation may occur in which the hair of the worker, the fiber waste of the clothes, and the like are mixed in the package. Therefore, in the food industry, there has been a strong demand for an automatic device or the like that effectively eliminates contaminating foreign substances. However, there has been no known device capable of responding to this.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to expose a food or the like immediately before packaging to a flame for a very short time to burn off combustible foreign matter contained therein and remove the foreign matter from the food. It is an object of the present invention to provide an apparatus for removing contaminants such as foods, which can prevent a situation such as being mixed in a package.

Means for Solving the Problems In order to achieve this object, a configuration of the present invention is to provide a net conveyor that circulates and runs in a horizontal direction, and a burner cylinder is provided below a transport surface thereof in a direction perpendicular to the running direction of the net conveyor. The gist of the present invention is that the blower device is provided at the end of the net conveyor.

The net conveyor can form a reversing part in the middle of the conveying surface, and in this case, the burner cylinder may be arranged before and after the reversing part. Further, the burner cylinder can be arranged so as to be vertically movable.

According to such a configuration, when transporting food products or the like in bulk on the transport surface of the net conveyor, the net conveyor is
Since the flame from the burner cylinder can be transmitted above the conveying surface without blocking, the combustible foreign matter mixed in the food or the like can be removed by incineration. At this time, by adjusting the traveling speed of the net conveyor, the time during which the food on the conveying surface is exposed to the flame of the burner cylinder is adjusted, and the flammable mixture in the food or the like is changed without changing the quality of the food. Adjust so that only foreign matter burns.

In addition, since the net conveyor can pass an object having a size smaller than the mesh, combustible or non-combustible contaminants having a size that can pass through the mesh can be simultaneously dropped and removed. .

Burning residue of foreign matter remaining after burning by the flame of the burner cylinder is removed by blowing air with a blower device at the end of the net conveyor.

If the reverse part is formed on the transport surface of the net conveyor,
In this portion, the food or the like on the conveying surface can be agitated or inverted. If a burner cylinder is provided before and after that, the flame can be uniformly applied to the food and the like.

In addition, in the case where the burner cylinder is vertically movable, the distance between the conveying surface and the burner cylinder can be changed. The optimum position of the flame of the cylinder can be easily set.

 It works as described above.

The lifters 50, 50 can be moved to an arbitrary height and stopped by operating the lifters 50, 50 (two-dot chain line in FIG. 2).

The blower device 30 is provided at the end side of the net conveyor 10 with the first blower.
It is attached so as to blow air in the direction of arrow K2 in the figure. The blower device 30 includes the frame plates 11, 11 of the net conveyor 10.
It is provided on a base 31 straddling it, and its opening 30a
The blow direction can be adjusted by the angle of the guide plate 32 attached to the guide plate 32, and a movable damper 33 that can move forward and backward toward the guide plate 32 is provided, so that the air volume can be adjusted. A removable dust receiving tray 34 is disposed almost directly below the blower device 30.

In using such a device for removing contaminant contaminants such as foods, first, the lifters 50, 50 are operated to move the moving table 51 up and down, so that the burner cylinders 20, 20 and the net conveyor are moved.
Optimally adjust the distance from the 10 transfer surfaces A. This interval is
Generally, the degree to which the tip of the flame from the burner cylinders 20 reaches the transport surface A is the best.

Next, if the net conveyor 10 is operated and foods and the like are continuously put on the conveying surface A from the starting end side (arrow S in FIG. 1), the foods and the like first pass through the first burner cylinder 20. Since it passes through and is exposed to the flame of the burner cylinder 20, flammable contaminants such as hair and clothing fiber waste are almost immediately burned and removed. Here, the food and the like are affected by the heat of the burner cylinder 20 because the food and the like are heated by the pair of heat insulating plates 21 and 21.
, And is limited to a very short time at a position immediately above the burner cylinder 20. At this time, by changing the traveling speed of the net conveyor 10, the time for exposing the food or the like to the flame can be adjusted so that the quality of the food or the like does not change at all and only the contaminant foreign matter can be incinerated.

In this way, at least the food or the like from which the contaminant foreign matter on the side in contact with the conveyor net 13 has been removed advances to the reversing section ST as the transport surface A moves, and the upper conveyor roll
It falls sequentially from the 12f side to the lower transport surface A. Therefore, the food and the like are subjected to a moderate impact, the alignment order is changed, agitated or inverted, and the contaminant foreign matter remaining on the inner side or the upper side of the food or the like is shaken down on the conveyor net 13. Then, the burner cylinder after the reversing part ST
By passing over the upper part 20, the remaining contaminant foreign matter is incinerated.

Before and after the reversing section ST, the food and the like that have undergone incineration twice are blown at the end side of the net conveyor 10 by a blower device.
It is exposed to the blast from 30 and blows off the scum and the like of the contaminating foreign matter, removes it, and discharges it to the outside via the discharge guide plate 11b. In addition, dregs and the like that fall downward through the conveyor net 13 are stored in the dust tray 34.

In the above description, the blower device 30 optimally adjusts the air pressure and the air volume of the blower device 30 in order to blow off only the slag of the contaminant mixed in the food or the like on the transport surface A. In order to obtain a wind pressure as uniform as possible in the width direction of the net conveyor 10, a plurality of small-capacity units may be provided in parallel.

The flame from the burner cylinders 20, 20 raises its temperature to a high temperature,
In order to generate no soot and achieve a sharp temperature distribution in the running direction of the net conveyor 10, it is preferable to use the outer flame portion of a long flame that has been completely burned. Further, it is preferable to use a low-pressure gas as a gas pressure supplied to the burner cylinders 20 for safety.

Effect of the Invention As described above, according to the present invention, the burner cylinder is provided below the transfer surface of the net conveyor, and the blower device is provided at the end side of the net conveyor. Inflammable contaminants such as input foods can be incinerated and removed by flame from the burner cylinder,
In addition, since the residue can be blown off and removed by a blower device, contaminants such as food in the process immediately before packaging can be removed extremely hygienically and in a short time. There is an excellent effect that it is possible to effectively avoid the situation of being packaged together.
