Description

[Technical field]

[0001] The present invention relates to a rice milling plant system used in a rice milling factory. [Background technology]

[0002] As part of the rice milling plant system, multiple foreign object sorting machines are installed in the receiving yard. After sorting and removing foreign matter from the brown rice that arrives, the brown rice processing plant is equipped with a number of brown rice tanks. The rice is sent to a storage yard, stored in brown rice tanks according to arrival number, and then sent to the rice milling yard. A rice polishing machine is installed, and the brown rice sent from the brown rice tank is polished according to the specified conditions for each lot. A machine for sorting broken rice is installed after each rice polishing machine, and the broken rice is mixed into the polished rice produced by the rice polishing machine. Broken rice is sorted and removed, and the rice is sent to a polished rice storage yard equipped with numerous polished rice tanks. The shipping yard is equipped with multiple colored rice sorting machines, and the polished rice is stored and managed separately. The colored rice mixed in is sorted out and removed, then it is packaged in a packaging machine and shipped as white rice. There is provided one (see, for example, Patent Document 1).

[0003] In addition, in this type of rice milling plant system, the process was previously carried out from the brown rice tank to the rice milling machine, and then from the rice milling machine to the rice milling machine. The rice produced from the rice mill is sorted and blended by various machines, and many chains are used to transport the rice between each process. Conveyors and lifts are used, but these conveyors are large and require large capacity. In addition to the problem of high storage costs, rice and bran can remain in the gaps, causing mold and insects to grow. To solve these problems, air was supplied using a blower or compressor. A method has also been proposed in which rice is pneumatically transported by generating an air current inside a pipe (for example, For example, see Patent Documents 2 and 3.

[0004] However, the equipment used in each process, such as rice polishing machines, various sorting machines, and packaging machines, requires maintenance. For reasons such as maintenance, the equipment is basically an open system, so there is a risk of insect infestation within the rice milling factory. This can cause dust to spread, and furthermore, insects in the factory can get into the equipment and attach to the rice. Even if air conveyance is adopted as described above, it is still necessary to take measures against insects in the entire factory. This type of insect control cannot be done with insecticides due to hygiene issues, and cleaning is required. Even if they could, it would be extremely difficult and costly, and the brown rice delivered may already have insects in it. There were many cases where the rice was mixed with insects, and there were certain limitations. The current situation is that they are plagued by complaints.

[0006] In view of the above situation, the present invention aims to solve the problem of the conventional open system. Even though we use state-of-the-art equipment, rice milling plants are less likely to have insects, and the rice produced is free of insects. The point is to provide a plant system. [Means for solving the problem]

[0007] As a result of intensive research into solving the above-mentioned problems, the inventor of the present invention has found that the problem of dust generation and the possibility of insect intrusion Each piece of equipment that may be used for this purpose is stored in a small, almost sealed room, and the equipment is provided with a communication path between the previous and next processes. If the two are connected in a nearly sealed manner, any dust that may be released can be contained within the small room, and conversely, the dust can be contained within the factory. Even if there are insects, they can be prevented from entering the equipment in the small room, and insect control measures can be implemented for the entire factory. In comparison, we found that it is possible to prevent insects from attaching to products at a very low cost and with certainty. The invention was completed.

[0008] That is, the first invention is to construct a substantially sealed small room in a rice milling factory and use it in a rice milling plant. The equipment to be used for the process is installed in the small room, and the communication path between the previous and next processes is roughly densely connected to the equipment. A rice milling plant system characterized by being connected in a closed state is provided.

[0009] Furthermore, the inventors have found that even if brown rice has insects attached to it, it will be polished under high pressure in a rice polishing machine. In the process, the insects are crushed and their carcasses are expelled along with the bran, leaving the processed rice free of insects. Focusing on the fact that the rice milling machine and packaging machine are in a state where ... If the containers are stored in small compartments and connected in a nearly sealed manner with a connecting passage, it is possible to prevent insects from entering the product. They also discovered that this can be prevented, thus completing the second invention.

[0010] That is, the second invention is to construct multiple substantially sealed small rooms in a rice milling factory, and to transport rice from the rice milling machine to the rice mill. Some or all of the multiple pieces of equipment used in a rice milling plant, including the equipment for the rice milling plant, The small rooms are installed indoors and are connected by nearly sealed passages. The present invention also provides a rice milling plant system having the following features.

[0011] In these inventions, "almost sealed" means that the open part is provided with an insect-proof net so that insects cannot pass through. Or, air curtains or other devices are used to prevent insects from entering. Excluding the internal space of the piping and wiring for sending grains, bran, etc. to the designated location and each duct for air conditioning, etc. This includes those that are nearly sealed. In addition, in a nearly sealed communication path, a tank is inserted in the middle in a nearly sealed manner. This also includes those who have been

[0012] The third invention is to construct a small room in a rice milling factory and store the equipment used in the rice milling plant in that room. A heating means is provided in the room to raise the temperature in the small room to a predetermined temperature. The present invention also provides a rice milling plant system comprising: It is preferable to use heat insulating materials throughout.

[0013] In particular, the heating means is a heater provided in the device disposed in the small room. is preferred.

[0014] It is also preferable that the plurality of small chambers are provided at positions gradually lower in the process order.

[0015] It is also preferable to provide an air curtain at the outlet through which the packaged rice is discharged from the small room in which the packaging machine is installed. Alternatively, a blower with an insect-proof net is provided on the wall or ceiling of the small room in which the packaging machine is installed to circulate the inside of the small room. Pressure It is preferable to exhaust the gas from the exhaust port. Effect of the Invention

[0016] According to the rice milling plant system of the present invention, a substantially sealed environment is provided in the rice milling factory. A small room was constructed, and the equipment used in the rice milling plant was installed in the small room. The equipment has a nearly sealed connection between the front and back processes, preventing dust from entering the equipment. Even if rice comes out, it is contained within those small rooms, and communication is not possible between the previous and next machines. Since the passage is connected in a nearly sealed manner, it is possible to prevent dust from scattering outside the small room. This can prevent dust, which can cause insects to breed, from being scattered from the small room into the rice milling factory. The small room can also prevent insects from entering the equipment from the outside, and the semi-finished products or Insects will not get into the product. In addition, dust may be generated in the small room, which may cause insects to breed. In the case of insects, the insects are killed by temporarily heating a small room instead of the whole factory, or insect control measures such as cleaning are taken. This makes insect control easier and more reliable, and reduces costs. By installing the device in a small room like this, insect control can be achieved with little human or thermal energy. Not only that, but it will also be possible to individually and precisely control various environmental conditions such as temperature and humidity. do.

[0017] In addition, multiple small, nearly sealed rooms were constructed within the rice milling factory, and a series of machines from the rice milling machine to the packaging machine was A part or all of the equipment used in the rice milling plant is installed in the above-mentioned small rooms. In addition, these small rooms are connected by almost sealed passages, so dust does not come out of the equipment. The rice is also contained in a small room, and the rice is transferred between the front and rear rooms through a passage that is almost sealed. Since the faucet is connected in a circular fashion, it is possible to prevent dust from scattering outside the small room, and the entire rice milling factory is free of insects. This can prevent the scattering of dust that can cause problems.

[0018] In addition, the small room can prevent insects from entering the equipment from the outside, In addition, dust is generated in the small room as mentioned above, and there is no risk of insects getting into the products or goods. Therefore, even if insects occur, it is only necessary to take measures against insects in a small room, not in the entire factory. This makes it easier and more reliable, and reduces costs. This makes it possible to individually and precisely control various environmental conditions such as temperature and humidity. In addition, the small rooms are connected by almost sealed passages, so the equipment is not directly connected to each other by a passage. Even without this, it is possible to prevent dust from scattering in the factory between small rooms, and on the other hand, to prevent insects from entering. This can be prevented.

[0019] According to the present invention, even if there are insects in brown rice, they are crushed in the rice mill and the dead insects are removed from the rice bran. The rice processed by the rice mill is insect-free and is then discharged with the rice in a roughly sealed container until it is packed. Since the rice is processed in a closed room and connected to each device, the product (rice) is susceptible to insects. In addition, by taking measures against insects in each small room, the internal machinery can be prevented from being attacked by insects. The container can prevent dust from scattering and insects from entering the product even in an open system, allowing for freedom of design. increases.

[0020] In addition, a small room will be constructed in the rice milling factory, and the equipment used in the rice milling plant will be installed in that room. In addition, a temperature raising means is provided for raising the temperature in the small chamber to a predetermined temperature. Even if insects invade or appear in the room, the insecticidal effect is temporary and requires little energy. Since it is a small room rather than an entire factory, the temperature can be raised efficiently. This is possible at a very low cost and does not adversely affect the workability of workers in the factory. It is also possible to raise the temperature to a higher level than was possible in the entire factory. It is possible to obtain a good insecticidal effect.

[0021] In addition, a heater was installed in the equipment placed in the small room as a means of raising the temperature, so the equipment itself This allows the use of power, which reduces costs compared to setting up separate facilities, and also reduces the size of the equipment casing, etc. Heat can be transferred more directly and at higher temperatures to achieve an effective insecticidal effect.

[0022] In addition, an air curtain is installed at the outlet where the packaged rice is discharged from the small room where the packaging machine is installed, or the inside of the small room is given Pressure Since the packed rice is exhausted from the outlet through which it is discharged, it is possible to prevent insects and the like from entering the small room from the outside of the outlet, which is difficult to seal.

[0024] Next, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

[0025] As shown in FIG. 1, the rice milling plant system S of the present invention is a substantially sealed small rice milling plant P. Rooms R01 to R12 are constructed, and devices 103 to 120 are installed in the rooms R01 to R12. At the same time, the devices 103 to 120 are provided with communication paths 301 to 315 between the previous and subsequent processes. The device 101 is characterized by being connected in a sealed manner. Specifically, the device 101 is slightly larger than a grain of rice. The machine 102 is a raw material weighing machine, and the symbol 201 is a brown rice tank (combined). In addition, the equipment 103 is a brown rice weighing machine, the equipment 104 is a rice mixing machine, the equipment 1 05 is a rice polishing machine, 106 is a grain sorting machine that separates crushed grains, and 107 is a machine that separates metals that stick to magnets. The metal selector to be removed, reference numeral 202 is a white rice tank.

[0026] In addition, the device 108 is a grain sorting machine for sorting rice bran balls, the device 109 is a polished rice weighing machine, and the device 110 is The no-rinse rice processing machine, Equipment 111, is a stone removal and sorting machine that separates stones and other grains with a high specific gravity. 2 is a sorting machine that sorts out grains slightly lighter than rice grains, and equipment 113 and 114 are colored grains and glass. The glass and color sorting machine is used to separate foreign objects, the equipment 115 is used to separate crushed particles, and the equipment 1 Number 16 is a metal sorting machine that separates metals, and number 117 is a machine that separates light-weight materials such as dust and insects. Insect separator, device 118 is a metal selector that removes metals that stick to a magnet, code 203 is a product tank (or tanks). Also, equipment 119 is a weighing and packaging machine, equipment 120 is a metal detector for detecting metal in a bagged product, and device 121 is a bagged product It is a piler that stacks materials onto pallets.

[0027] In addition, the piping that is connected to each of these devices, such as foreign matter, bran, crushed grains, bran balls, stone rice, coloring The piping for sending the particles, etc. to the designated location is not shown, but it can be set arbitrarily. 101 to 121 can be widely used, including those that have been known in the past. The system is not limited to using these devices, and may be composed of only some of these devices. Systems that do not use rinse-free rice processing machines or systems that use other equipment are also included. Also, other configurations are possible for the arrangement of the sorters and detectors.

[0028] The small rooms R01 to R12 are located within the floor space of the rice milling factory P and are used to enclose separate equipment in a nearly sealed manner. It is a small room with a partition wall, and only requires storage space for equipment and maintenance work space. It is a nearly sealed room with a minimum of internal space. However, the number of small rooms has been reduced. The number of devices stored in each small room can be increased or decreased. It is not necessary to install all the devices used in the event in the small room. 02 and 121 are not installed in the small room. Equipment for processes after the rice polishing machine and other equipment that is prone to producing dust are not installed in the small room. It is also effective to place only the equipment that requires a small room in the small room. This also applies when:

[0029] In this way, there is no need to install each device individually in a small room. In R01, R05, R09, R10, R11, and R12, multiple devices (two in this example) The number of machines (usually 1, but 3 or more machines may be used) is set up in the same small room. Which of the multiple devices used in the runt system should be installed in the small room and which Install them individually, or install multiple devices together in one small room, or install multiple devices together in one small room. The choice of whether to consolidate all equipment into a small number of small rooms or not depends on the suitability of each equipment and maintenance. It can be appropriately selected depending on various conditions such as maintenance, transport efficiency, and temperature control.

[0030] However, it is preferable that at least the series of equipment from the rice polishing machine 105 to the weighing and packaging machine 119 in the downstream process be installed in the minimum number of small rooms R02 to R12, and that these small rooms be connected by approximately sealed communication paths 303 to 314 (tanks may be interposed between them). Even if there are insects in the brown rice, the rice processed by the rice polishing machine becomes insect-free, and if the intrusion of insects can be prevented from occurring during the period until the rice is packaged by the packaging machine, it is possible to reliably prevent insects from attaching to the product (rice). However, the discharge port 54 of the small room R12 is opened to discharge the packaged rice bags 9, and therefore cannot be kept sealed like the other small rooms. Therefore, the discharge port 54 of the small room R12 in which the packaging machine 119 is installed is provided with an air curtain 4 to prevent insects from intruding, as shown in FIG. 4, or a fan with an insect-proof net on the wall or ceiling of the small room R12 (neither is shown) is used to circulate the air inside the small room R12. press In either case, the rice bags 9 are transported to the external piler 121 by the inner and outer conveyors 8A and 8B from the discharge outlet 54 while preventing insects from entering the bag.

[0031] The communication paths 301 to 315 are, for example, chutes or air conveyance by a suction method or a pressure feeding method (for example The above-mentioned Patent Documents 2 and 3, JP-A-2005-306514, and JP-A-2005-29671 Conventionally known rice transport ducts and screw conveyors that can transport rice (Publication No. 6, etc.) A substantially enclosed delivery means may be used and may be directly connected to the device (118) as shown in FIG. The rice delivery duct itself may be configured as the connecting passage (313), or as shown in FIG. As shown in the figure, the inside of the passage (312) that connects the small rooms (R10, R11) in a substantially sealed state In the case where a separate conveying means is provided as shown in FIG. The conveying means itself can be an open system such as a conveyor or elevator. Transportation of rice between multiple devices installed in a room, for example, between 108 and 109 in the example in Figure 1, The means of transporting rice between 113 and 114 should be closed, but an open system is also acceptable. .

[0032] A part or all of the inner surface of each of the small rooms R01 to R12 is made of a heat insulating material (not shown). Both are provided with a heating means (not shown) for raising the internal temperature to a predetermined temperature. For example, an electric infrared stove can be installed to raise the temperature to about 50°C, which will eliminate any insects that may appear. The equipment itself is also equipped with a heater, and the equipment case is heated. These are designed to provide direct and efficient insect control measures. The means preferably has an automatic temperature control function.

[0033] In this way, there are many advantages to installing some or all of the equipment in the rice milling factory P in a small room. However, the doors of the small rooms must be opened and closed every time an instrument is operated or a sample is sampled, and workers must enter and exit the rooms. However, there is a way to overcome this problem, for example in rice mills. The inside of the rice milling factory P may be configured as follows. A separate control room equipped with a remote control device is provided, and workers in the control room can The control unit of the control device is operated to remotely control each of the devices 101 to 121. In this case, the control room It is desirable that the small rooms R01 to R12 are configured to be substantially sealed from the outside. Each of the devices 101 to 118 has a sample extraction valve that can be opened and closed by remote control from the control room. A device is installed, and its opening and closing is connected to the control room by a rice sending duct, and the work in the control room is Any person may obtain a small sample of rice from any device through the rice delivery duct.

[0034] It is desirable to obtain the sample in a very short time in real time. Therefore, the rice delivery duct is used for air conveyance by suction or pressure (for example, the above-mentioned patent document). References 2 and 3, JP 2005-306514 A, JP 2005-296716 A, etc. (Air conveying method disclosed in the previous article) and a chute using free fall from top to bottom, and a combination of these. etc. are preferable.

[0035] In this way, workers can remotely access each device from the control room without having to go to each room where the device is installed. This allows the equipment to be operated and adjusted with a single touch, resulting in extremely high efficiency compared to conventional systems. This reduces the number of workers, and the layout of the small rooms R01 to R12 is also convenient for workers to get around. It can be designed freely without considering the future, and dust is generated from the small room when workers enter and exit the room. This may cause insects to get into the small room or workers' hair to get into the product. It also has the effect of preventing such things from happening in the first place.

[0036] Although the embodiments of the present invention have been described above, the present invention is not limited to these examples. The present invention is not intended to be limited to the above, and may be embodied in various forms without departing from the spirit and scope of the present invention. Of course.
