Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a deworming method for machinery in which a plurality of machines such as a milling machine are continuously installed for each processing step, and more particularly to a safe and efficient deworming method for a continuous machine using heat.
[0002]
[Prior art]
The milling process is composed of several processing processes, and a machine for each processing process is continuously installed in the milling factory so as to form a series of milling processes. Each processing machine in each processing step has a rotating part, a vibrating part, and the like inside, and raw wheat is conveyed at a predetermined speed. However, inside each machine, there are corners and gaps instead of continuous smooth curved surfaces. Then, there are places where the flow of the raw material is stagnated in such corners and various gaps, and insects may enter the places where the flow is stagnant.
[0003]
And such insects (here, insects are beetles with adult body lengths of 4 mm and 2 mm, respectively, such as slats of the moss, worms, and the insects themselves have toxins and pathogens. In order to prevent accidental inclusion in the product, conventionally, when the machine is stopped, such as on holidays, the worker cleans the inside of the machine to remove deposits, It was.
[0004]
Further, it is known that there is a method for heating and treating the whole factory as an anthelmintic method overseas and the like.
[0005]
[Problems to be solved by the invention]
However, since the inside of the machine is narrow and has various driving parts inside, the cleaning work is troublesome and the fine parts have to be focused on, so the burden on the operator is large. Moreover, although it takes time to sufficiently clean, there are problems such as adjustment of the downtime of the factory and securing a large number of workers for performing the cleaning work in a short time.
[0006]
In addition, the method of deworming by heating all the inside of the mill to a predetermined temperature requires that the windows, doors and other openings installed in the factory be sealed so that heat does not escape. There was a problem that it took a lot of time and labor. Also, in order to heat the whole factory, very large heat energy is required, and furthermore, it takes time to transfer heat, so it takes several tens of hours to raise all parts to the anthelmintic temperature. There was also a problem in terms of productivity.
[0007]
On the other hand, when the machines in the mill are individually heated, the various processing machines installed in the mill are connected to other machines by pipes, etc. Heat escaped to the machines, and it was difficult to heat each machine sufficiently.
[0008]
Specifically, for example, in a mill, a roll machine is placed on the lower floor, and a shifter is placed on the upper floor. Other types of machines are connected to each other using a transfer pipe. Then, the semi-finished products processed on the upper floor are sequentially transferred by gravity to the lower floor machine by a pipe called sport, and the semi-finished products processed on the lower floor are usually transferred to the top floor by an air transport pipe called a pneumatic pipe. Has been transferred to. Therefore, since each machine is connected to another machine by a pipe, heat escapes through a sport or a pneumatic pipe, and it is difficult to locally heat only one machine.
[0009]
In addition, since parts that are vulnerable to heat, such as electrical equipment, are arranged in the factory, when the entire factory is heated, these equipment may be damaged.
[0010]
The present invention reduces the burden on a worker who performs anthelmintic work, can be easily and reliably performed by a small number of workers, and is safe for the human body and equipment, and has a plurality of machines such as a milling machine. It is an object of the present invention to provide a method for deworming a continuous machine capable of reliably deworming in a short time and with a small amount of heat energy even when the types are connected by pipes.
[0011]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention divides a series of processing machines in which a plurality of machines are connected by pipes or the like as appropriate, and heats each of the divided machines to carry out deworming.
[0012]
In particular, milling machines, etc. pay attention to the fact that the machines in each processing step can be separated from the connection of the processing paths relatively easily and that the temperature required to kill insects and their eggs is not so high. At the factory, the connected machines are appropriately separated along the processing path, each separated machine is partitioned with a flexible sheet-like member such as cloth, and hot air is sent into the partitioned internal space. Then, each divided machine was heated to drive insects and their eggs inside the machine.
[0013]
Since the main insect pests and their eggs that adhere to wheat flour and the like are surely killed when heated to 60 degrees or more, warm air of about 80 to 120 degrees is sufficient. The time for blowing warm air is based on the time at which the temperature inside the machine is most difficult to raise, for example, the inside of the powder deposited at the corner of the machine reaches the predetermined temperature required for the anthelmintic. Usually, it is sufficient to blow warm air for about 120 minutes, and it is appropriately selected depending on the outside air temperature during the deworming operation, the size of the machine to which the deworming is performed, the hot air temperature, and the like.
[0014]
Specifically, the maximum thickness of the powder that may have accumulated inside the machine is estimated, and the maximum is obtained from the time during which the interior of the portion rises to a temperature at which insects and eggs are completely killed. Thereby, even when insects and eggs are contained in the powder, it is possible to surely drive insects. When it is necessary to keep the temperature constant, the holding time is included in the predetermined time.
[0015]
The machine may be divided for each processing step, or a plurality of machines in a plurality of processing steps may be divided into a single unit, or a machine in one processing step may be divided into a plurality of units. Good. Further, a plurality of machines arranged in series may be collected, or a plurality of machines arranged in parallel may be collected. When a plurality of machines are combined, care should be taken so that the machines on the downstream side of the hot air and the machines arranged at the ends are sufficiently heated.
[0016]
The blowing of warm air into the machine is not limited to the direction of processing inside the machine, and the hot air may be blown from the opposite direction or from the middle part of the machine and flow in the front-rear direction of the machine.
[0017]
The generation of warm air may be provided with a blower and a heating unit, and a portable device is preferable. The heat source of the heating unit is not limited to electricity, steam, and other types. The amount of air to be blown in varies depending on the size of the machine to be heated, but is 2 to 50 m @ 3 / min, preferably 5 to 10 m @ 3 / min. Further, the amount of blown air is appropriately increased or decreased depending on the presence or absence of the cover.
[0018]
Furthermore, the heating of the machine is not limited to hot air, and other heating devices such as a combustion device and an infrared irradiation device may be used.
[0019]
A partition member that partitions the machine, it is effective nylon filter cloth with a breathable, to further, arranged cloth inside breathable, by arranging the fabric without breathable outward between two parties A high effect can be obtained when the double structure is provided with voids .
[0020]
Furthermore, the partition member is not limited to a cloth-like member, and may be an assembly-type panel member or the like.
[0021]
Also, when the machine itself is highly sealed, the machine is not covered with a partition member, but hot air is blown directly into the machine from the machine inlet and outlet, and the whole machine is heated by passing the hot air. You may do it. Further, it is more effective if the hot air that has passed through the machine is made to travel around the machine.
[0022]
In this way, it is possible to completely deworm by heating each machine, and further, by carrying out the deworming work sequentially on each machine, it is possible to carry out the deworming work of all machines. Thereby, it is not necessary to seal the whole factory, and it is possible to reliably and safely perform deworming of machinery.
[0023]
Moreover, although the temperature of the warm air to be used is 80-120 degree | times, even if it hits skin directly, since a humidity is low, a burn will not generate | occur | produce. In addition, the temperature of the machine itself is not so high, and heating can be performed while avoiding portions that are vulnerable to heat as appropriate, so that the operating portion and the control portion are not damaged.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of a method for deworming a continuous machine according to the present invention will be described.
[0025]
In FIG. 2, the whole structure of the milling factory 30 is shown. The milling factory 30 is a 5 to 6-story building, and storage tanks 32 and 34 are provided on the left and right sides of the building, and processing machines are installed on each floor. For example, a roll machine 36 is installed on the third floor, a purifier 38 is installed on the fourth floor, a shifter 40 is installed on the fifth floor, and a filter 42 is installed on the sixth floor. These processing machines are connected by a pipe 44, and a product is stored in a storage tank 34 on the right side of the figure by an ascending powder conveyor 46.
[0026]
In the deworming work, first, each connected machine is divided appropriately. That is, the connecting pipe connecting each machine is removed from the machine mounting portion or the like, and the connection with the front and rear machines is released. Then, the entire machine is covered with a cloth as shown in FIG. 1, and a blower port of the warm air device is inserted into the cloth. At that time, in order to measure the temperature of the machine, a thermometer may be installed in the machine in advance.
[0027]
Thereafter, hot air of a predetermined temperature is blown into the inside from the hot air device to heat the machine. A warm air apparatus consists of an electric heater and an air blower. The warm air blown into the cloth flows into the machine, contacts the outer wall, etc., heats the machine, and gradually passes out through the cloth. If hot air is blown into the cloth for a predetermined time, the blowing of hot air is stopped and the cloth is removed.
[0028]
In this way, the entire machine is heated almost uniformly to a predetermined temperature, and even if insects and their eggs are attached to the machine, or insects are lurking in the powder remaining inside the machine, it is surely killed. Can do.
[0029]
Therefore, if the entire machine is heated to 60 degrees or more, the attached insects and the like are killed, so that less heat energy is required and the milling machine can be easily and reliably carried out. Further, by carrying out such operations sequentially for all the machines, it is possible to carry out the deworming of the machines of the whole mill.
[0030]
(Experimental example 1)
FIG. 1 shows the blanc finisher 2 used in the experiment. The Blanch finisher 2 is installed at the subsequent stage of the milling process, and is a machine that is relatively easy to accumulate powder among the machines used in the mill.
[0031]
The blanc finisher 2 is a machine that further separates the flour from the bran portion that is the skin of wheat. A cylindrical net (not shown) is fixed inside, and the center of the net is rotated coaxially with the net. A wheat beater with a shaft (not shown) is rotatably attached. When the wheat raw material is introduced into the net from the insertion port 4, it is rubbed by the beet, and the flour on the bran portion is removed and recovered. The bran is left on the net and left.
[0032]
The used blanc finisher is BF1-45110 type manufactured by Meiji Machinery Co., Ltd., having a width of 560 mm, a length of 1220 mm, and a height of 730 mm. As the cover 6 hung on the whole, a nylon filter cloth having air permeability and a nylon taffeta having almost no air permeability were used. A column may be set up on the upper part of the blank finisher 2 so as to keep a space between the cover 6 and the cover 6.
[0033]
On the other hand, as shown in FIG. 3, a plate material 8 is attached to the inside of the braun finisher 2, and the wheat flour 20 is deposited on the flour material 20 in a thickness of about 40 mm. (Not shown).
[0034]
In such a state, hot air of about 80 degrees is generated by an erotic fin heater (not shown) using steam, and the temperature and the amount of hot air are changed from the blow pipe 11 to the inside of the blow finisher 2 from the outlet 10 side. Blowing was heated to a predetermined temperature, and the number and temperature of pests were measured.
[0035]
The results are shown in FIG. As a result, it was found that when the temperature of the machine exceeded 60 degrees on average, the insects inside could be completely killed. NF is a nylon filter cloth and NT is nylon taffeta.
[0036]
Test d is a similar experiment with the cover 6 changed. This was carried out in the same manner as in the above experiment by placing a cotton cloth having air permeability on the inside and hanging a nylon taffeta having no air permeability on the outside. As a result, it was possible to raise the blanc finisher 2 to a predetermined temperature with less energy.
[0037]
From the above experiments, it can be seen that the case where the machine is covered with a breathable cloth or the like is more effective in raising the temperature (comparison between tests b and c). If there is plenty of hot air to be blown in, using a cloth with moderate breathability will cause the hot air to ooze out from the inside to the outside, and the inner space and the outside in the boundary layer with the outer surface of the cloth It is estimated that the temperature of the cloth itself is equivalent to the temperature of the hot air in the internal space, making it difficult for heat to escape to the outside. On the other hand, in the case of a non-breathable cloth, the temperature in the boundary layer with the outer surface of the cloth is equivalent to the outside air temperature, and the temperature of the cloth itself is about the average value of the outside air temperature and the internal hot air temperature, When the flow of hot air in the interior comes into contact with the fabric, it will flow out through the fabric, which will be disadvantageous for the temperature rise in the internal space.
[0038]
In addition, it can be seen that it is more effective to use a cover on the inside and outside, and to use a material having air permeability on the inside and a material having low air permeability on the outside (comparison between tests c and d). This is because the hot air circulation is very good inside the well-ventilated inner fabric and the hot air is distributed to each part of the machine, so that it can be heated uniformly and efficiently, and the outer sheet material releases heat. This is because the gap is formed between the two and acts as a heat insulating layer.
[0039]
(Experimental example 2)
Next, a heating experiment using another milling machine will be described.
[0040]
FIG. 5 shows the purifier.
[0041]
As shown in FIG. 5, the purifier 50 was covered with a cover 6 made of nylon filter cloth and nylon taffeta to cover the upper and side surfaces of the purifier 50. And the blowing pipe 11 of the heater (not shown) was inserted in the inside of the cover 6, and hot air was blown in. At that time, the position of the tip of the blowout pipe 11 was set to the substantially center inside the cover 6.
[0042]
The same heater as in Experimental Example 1 was used. The air volume was 10 m <3> / min, the temperature of the warm air at the outlet portion of the blowing pipe 11 was about 90 degrees, and the blowing time was 170 minutes. Attach thermometers to the left and right feeder mouths (a in Fig. 5) inside the residual powder, near the center of the left and right shaking chutes (b in Fig. 5), and the upper suction port flange (c in Fig. 5). It was.
[0043]
The hot air blown out from the blowing pipe 11 directly enters the interior of the purifier 50 and widely travels around the entire purifier 50 and heats it. As a result, the internal temperature of the powder remaining in the left and right feeder ports was 64 ° C, the temperature of the iron plate portion near the center of the left and right shaking chute was 76 ° C, and the temperature of the iron plate portion of the upper suction port flange was 73 ° C. It was.
[0044]
Further, the powder remaining inside was removed from the purifier 50 and inspected. Insect dead bodies were found from the residual powder, but no living insects were found. Further, the residual powder was put in a glass container and observed at 25 ° C. for 2 months. Insects were not found inside even after 2 months, and it was determined that the eggs were also killed by the heating.
[0045]
(Experimental example 3)
Next, an example in which the machine is directly heated without using a cover will be described.
[0046]
FIG. 6 shows a product collection conveyor 44 called an ascending powder conveyor.
[0047]
This conveyor 44 collects the wheat flour, which is the product that has passed through the sieve, by grade, and is one of five-row chain conveyors. The powder entrance is a plurality of ascending powder sports 24 corresponding to the number of exits of the sieve, and a multi-directional switching cut 26 is provided to determine which section of the conveyor 44 is to be put.
[0048]
In the experiment, all the connecting tubes 28 attached to the respective outlets of the sieve were first removed, the tubes 28 were bent to close the mouth, and the blowing port 21 was attached to the lid provided at the center of the conveyor 44. An air passage from a hot air source was connected to the air inlet 21, and a filter filter cloth 22 was attached as a breather on the head side and the tail side to prevent blowing of powder from the inside and to serve as a hot air exhaust port.
[0049]
And the warm air of 80 degree | times or more was blown from the blower inlet 21 in the center of a conveyor, and temperature was measured with the survival of the insect and the thermometer installed in the inside.
[0050]
Although it was confirmed that the warm air almost enters the respective sections of the conveyor 44, unlike the above example, since the hot air is actively discharged out of the machine, a large amount of air is required.
[0051]
As a result of the experiment, the entire conveyor 44 can be sufficiently heated to 60 degrees or more at which an insecticidal effect can be obtained, and a sufficient insecticidal effect can be obtained by increasing the internal temperature although the required air amount is increased.
[0052]
In a so-called ascending powder conveyor in a mill, it is only necessary to remove the tube 28 under the sieve without removing many complicated sport pipes. Moreover, the conveyor 44 itself is highly sealed and efficient. Since it is a place that is relatively difficult to clean during the process, a great effect can be obtained.
[0053]
In both the above experimental examples, the mechanical bearings and other parts of the machine are not affected by the temperature rise in this range, and the electrical parts, electrical components, etc. are outside the equipment, and the maximum temperature reached 45 degrees causes any trouble. There wasn't.
[0054]
Moreover, although the said example demonstrated the flour milling machine, this invention can be applied not only to it but another continuous machine.
[0055]
Furthermore, since each machine is heated, the equipment may be modified in advance so that the division and partitioning of each machine can be performed smoothly. For example, a separation mechanism may be set in the middle of the pipe, or a part of the partition plate may be installed around the machine so that the partitioning can be easily performed.
[0056]
【The invention's effect】
According to the anthelmintic method of the present invention, the central part of the powder deposited inside the machine can be sufficiently heated, so that the insects and their eggs can be completely killed and the occurrence can be prevented. it can.
[0057]
Since it is possible to carry out deworming for each individual machine using air of about 80 degrees which is relatively easy to handle, it is possible to carry out deworming work even when factory downtime and maintenance maintenance time are short.
[0058]
The work does not require special training, and can reduce the burden on the worker carrying out the deworming, and anyone can easily carry out the machine deworming work by such a method with a small number of workers.
[0059]
Once the deworming work is completed, normal operation is possible as soon as the machine temperature drops.
