[Conventional technology]

With the progress of westernization of eating habits, the demand for meat such as chicken eggs, beef and pigs (hereinafter referred to as "ingredients") has expanded dramatically, and it is the people's ability to supply these ingredients inexpensively and stably. It is an important issue from a living point of view. For this reason, it is required to realize the effect of expanding the production scale by mass-producing foodstuffs with high efficiency. Therefore, each livestock farmer is as cheap as possible for a large number of livestock such as chickens, cows, and pigs. Therefore, it is important for livestock management to stably obtain a highly nutritious compound feed.

【0003】

Due to the request for livestock management, a large amount of powdered grains (hereinafter referred to as "powdered raw material"), which are raw materials for inexpensive compound feed, are imported from overseas. Granular raw materials are often contaminated with Salmonella bacteria in the production area or during transportation. However, in a plant that produces compound feed, there is only a process of producing compound feed by subjecting powdered and granular raw material to a predetermined process, and there is no process of actively sterilizing Salmonella bacteria, so the compound is contaminated with Salmonella bacteria. Feed (hereinafter referred to as "contaminated mixed feed") is produced.

【0004】

For this reason, livestock such as chickens that have eaten contaminated mixed feed are infected with Salmonella, and people who eat the ingredients brought from these livestock are also infected with Salmonella. It was. Moreover, due to the development of distribution means, the scale of this food poisoning incident has become widespread and large-scale, and confidence in the safety of the supplied foodstuffs has been greatly shaken. I was forced into a serious situation where I had to give instructions such as obligatory display of the expiration date.

【0005】

In recent years, in order to deal with the above-mentioned serious situation, research on the properties of salmonella bacteria has been conducted, and the salmonella bacteria are killed when exposed to an environment maintained at a temperature of 60 ° C to 65 ° C for about 20 to 30 minutes. Was discovered, and with this discovery as a breakthrough, in consideration of safety and economy, a process of sterilizing Salmonella bacteria by blowing heated steam on powdered and granular raw material is a plant that produces compound feed. There is a proposal to install it in.

【0006】

[Problems to be Solved by the Invention]

However, the raw material is powdery, and in a certain amount of raw material that is supplied to the compound feed production plant and is commensurate with the production amount of the compound feed in a certain period of time, a large number of powder particles protrude from each other via air. Since the parts are densely packed due to contact and entanglement, and it is difficult for heat to be transferred from the outside to the inside, simply indirect heating from the outside is enough to out of a certain amount of raw material. Only a group of raw materials in the range located on the outside and in contact with the heat transfer surface can be raised to a temperature at which the above-mentioned Salmonella bacteria are sterilized.

【0007】

Therefore, even if indirect heating is performed with heated steam for a long time, Salmonella bacteria still survive in the powdery and granular raw material located in other areas such as the central part, and the above-mentioned fixed amount of powdery and granular material is still present. The state of contamination by Salmonella bacteria remains unresolved as a whole raw material, and even if an indirect heating process using steam is provided during the production process of compound feed to sterilize Salmonella bacteria, the contaminated compound feed is almost the same as before. There is a problem in the operation technology for sterilizing Salmonella bacteria, such as being produced.

【0008】

Further, the powdery and granular raw material is generally temporarily stored in an appropriate storage tank or the like until it is used for the production of the mixed feed, but in the conventional mixed feed production plant, it is used. Since there is no allowance to prevent new Salmonella bacteria from entering from the outside air into the conveyor or storage tank that transports the powdered raw material to the storage tank, it is necessary to use the processing container in the powdered raw material. Even if the salmonella bacteria are sterilized to eliminate the contamination, the salmonella bacteria are newly mixed and adhered to the powdery raw material from the outside air, and at the time of producing the mixed feed, the powdery raw material contaminated by the salmonella is mixed. There are also problems with transportation and storage technology, such as supplying feed to the production process.

【0009】

In view of the above circumstances, the present invention supplies steam while adjusting a certain amount of powdery and granular raw material to physical properties that easily transfer heat, and even if the time for supplying steam is short, a certain amount of powdery and granular material is supplied. A method and device for sterilizing salmonella bacteria by continuously humidifying and heating powdery and granular raw material substances that can be heated to a heat sterilization temperature at which the whole raw material is evenly killed and the temperature can be maintained for a certain period of time. Until the powdery raw material that has been sterilized with Salmonella bacteria is used for the production of the compound feed, it is used for the production of the compound feed with the addition of transportation and storage measures that can prevent the Salmonella bacteria from being mixed and adhered from the outside air. The powdery raw material that can be reliably stored in the absence of Salmonella until it is sterilized by continuously humidifying and heating the powdery raw material, and the powdery raw material that has been sterilized by Salmonella is isolated from the external environment. It is an object of the present invention to provide a method and an apparatus for drying / cooling, transporting and storing.

BEST MODE FOR CARRYING OUT THE INVENTION

According to the invention of claim (1), the invention of claim (2), and the invention of claim (5), first, the drive means is operated to rotate the rotation shaft, and the space is constant from the feeder. When an amount of powdered and granular raw material is flowed into a stirring container provided with a space for stirring in a single scraping flow direction via an inlet, a fixed amount of powdered and granular raw material is generated as a plurality of reserves. It is agitated by being scraped up in the space by the heating side stirring means, and floats and flows in a specific place in the space without being biased.

【0026】

At the same time, when the saturated steam is guided to the saturated steam flow passages of the indirect heat transfer heating jacket by the saturated steam and the rotation shaft, the indirect heat transfer heating jacket by the saturated steam is heated by the inflow of the saturated steam. Heat is transferred into the stirring container from a certain range outside the stirring container in contact with the jacket, and the injection direction is changed according to the rotation of the rotating shaft from each of the numerous saturated steam injection ports provided on the rotating shaft. Saturated water vapor is injected into the stirring vessel from the center side of the space where the stirring is performed in a single scraping flow direction.

By the injection of the saturated steam, a certain amount of powdery and granular raw material that is agitated in a single space in which it is agitated in the direction of the agitation flow and is suspended and flowed while being agitated is suspended and fluidized on the stirring center side. During this process, some saturated water vapor particles of the saturated water vapor jetted on the outer surface of the powdery raw material adhere. Then, due to the fact that the temperature of the powdery and granular raw material is relatively lower than that of the saturated water vapor, the saturated water vapor particles release latent heat and condense, so that heat is transferred to the inside of the powdery and granular raw material. In this way, the powdery and granular raw material is directly heated by the injected saturated steam.

After that, the directly heated powdery and granular raw material is suspended from the central side to the outer peripheral side of the space to be agitated in a single scraping flow direction in the stirring container by the stirring operation of the plurality of preheating side stirring means. Although it flows, it is indirectly heated by contacting a jacket for indirect heat transfer heating with saturated steam during this period. When direct heating and indirect heating with the saturated steam are continued for a predetermined time while being stirred by a plurality of preheating side stirring means, a certain amount of powdery and granular raw material is uniformly heated to close to the target heat sterilization temperature.

Then, an air barrier is set up in the cooling compartment to isolate it from the external environment, so low-temperature air, which is slightly higher than the outside air, comes into contact with a certain amount of powdery raw material in an environment where the invasion of Salmonella is blocked. To do. Due to such contact, the raw material is deprived of heat and the temperature is lowered, and at the time of contact, some dust is blown up in the cooling compartment. Immediately before the above-mentioned inflow, when the exhaust blower constituting the dust discharge mechanism is operated, the exhaust containing the soared dust receives the suction / discharge action of the exhaust blower, rises in the cooling section, and passes through the discharge port. It flows into the dust collector via the exhaust pipe. After that, the dust is removed by the dust collecting device, and the dust is discharged from the exhaust blower to the atmosphere via the outside air discharge air flow pipe.

【0059】

In such an environment where the invasion of Salmonella from the outside air is blocked by isolation from the external environment, when a certain amount of high-temperature powdery raw material near the heat sterilization temperature is cooled, the Salmonella is sterilized. A certain amount of the powdered and granular raw material that has been sterilized contains water suitable for storage without mixing and adhering new Salmonella bacteria, and is adjusted to the temperature of the raw material suitable for storage, and step 3 is executed. ..

【0060】

After that, the indentation fan attached to the dried / cooled powder / granular raw material transport line and the pressurized air supply pipe for storage is operated. Then, the outside air is sucked into the push-in fan through the sterile air filter, the salmonella bacteria adhering to the dust floating in the outside air are removed, and the air with a slightly higher pressure than the outside air is discharged from the push-in fan to dry and dry. It is supplied to the storage tank via the cooled powder and granular raw material transport line and the pressurized air supply line for storage, respectively. As a result, the dried / cooled powder / granular raw material transport pipeline becomes a transport environment in which an air barrier slightly higher than the outside air is stretched so that there is no Salmonella bacteria isolated from the outside environment, and the storage tank is from the outside air. A slightly high-pressure air barrier is installed to create a similar storage environment isolated from the external environment.

【0061】

Then, a certain amount of powdery and granular raw material in a state where the temperature of the raw material suitable for storage is adjusted to the temperature suitable for storage from the outlet provided in the cooling section of the drying / cooling cylinder and the salmonella bacteria do not exist. Is discharged, Salmonella bacteria enter from the outside air during transportation and are transported through the dried / cooled powder / granular raw material transport pipeline and flow into the storage tank. Then, even after flowing into the storage tank, it is stored in a state of being isolated from the external environment and in the absence of Salmonella, and step 4 is executed.

【0216】

Then, when the push-in fan 257 constituting the sterile high-temperature air supply mechanism 253 for drying is operated, the outside air is sucked into the push-in fan 257 via the sterile air filter -255, so that Salmonella bacteria in the outside air are removed and pushed in. Air whose pressure is slightly higher than that of the outside air is discharged from the indentation fan 257 by the fan 257 and flows into the air introduction pipe 259.

【0217】

【0218】

Then, the dry compartment 227 becomes an internal environment in which an air barrier is stretched to isolate it from the external environment and the invasion of Salmonella adhering to the dust floating in the outside air is blocked. Under such an internal environment, high-temperature air slightly higher than the outside air comes into contact with a certain amount of powdery and granular raw material, and the moisture contained in the powdery and granular raw material is evaporated. Then, when the exhaust blower 273 is operated immediately before the inflow of the high-temperature air described above, the high-temperature drying air that has completed heat exchange with the evaporated moisture rises in the drying section 227 due to the suction / discharge action of the exhaust blower 273.

Then, when the push-in fan 279 constituting the cooling sterile low-temperature air supply mechanism 275 is operated, the outside air is sucked into the push-in fan 279 via the sterile air filter -277, so that Salmonella bacteria in the outside air are removed and pushed in. Air whose pressure is slightly higher than that of the outside air is discharged from the indentation fan 279 by the fan 279 and flows into the low temperature air introduction pipe 281.

【0221】

With such an introduction, the cooling compartment 237 is filled with low temperature air slightly higher than the outside air and is always maintained at a positive pressure.

【0222】

Then, the cooling compartment 237 becomes an internal environment in which an air barrier is stretched and isolated from the external environment to prevent the invasion of Salmonella bacteria adhering to the dust floating in the outside air. Next, when low-temperature air slightly higher than the outside air comes into contact with a certain amount of powdery raw material under the internal environment, the powdery raw material is deprived of heat, the temperature is lowered, and some dust is generated. Soars into the cooling compartment 237.

【0223】

After that, the dust is removed by the dust collecting device 291 and is discharged from the exhaust blower 295 into the atmosphere through the air flow pipe 293 for releasing the outside air, and step 3 (f) is executed.

【0224】

Under such an internal environment, when a certain amount of powdery and granular raw material at a high temperature near the heat sterilization temperature is cooled, a certain amount of powdery and granular raw material remains in a state where Salmonella bacteria do not exist. Step 3 is carried out after the temperature of the raw material is adjusted to be suitable for storage while containing water suitable for storage.

[Effect of the invention]

According to the constitution of the invention of claim (1), the constitution of the invention of claim (2), the constitution of the invention of claim (5), and the constitution of the invention of claim (6), since it is powdery, heat inside. It is easy to transfer heat by effectively utilizing the thermodynamic properties of saturated steam and superheated steam, and sterilize by heating by direct heating with saturated steam and preheating by indirect heating. The temperature can be raised to near the temperature, and then the heat can be kept at a heat sterilization temperature that can sterilize Salmonella bacteria by direct heating and indirect heating with superheated steam for a certain period of time. Salmonella bacteria that are mixed and adhered deeply can be reliably sterilized with a small amount of steam. In addition, if a sterilization treatment for Salmonella bacteria using saturated steam and superheated steam utilizing the thermodynamic properties is carried out continuously in a fixed amount of a large amount of powdery and granular raw material substances mixed with and adhered to Salmonella bacteria, All of the large amount of powdery and granular raw material that meets the production plan of the compound feed can be used as the powdery and granular raw material that has been sterilized by Salmonella without consuming a large amount of steam.

Further, according to the configuration of the invention of claim (6), direct heating and indirect heating by saturated steam and superheated steam, respectively, can be performed while carefully flowing and mixing the powdery and granular raw material, so that the grains are hard inside. Even if it is a powdery and granular raw material that is difficult for water and heat to permeate into, the whole powdery and granular raw material can be raised to near the heat sterilization temperature and the heat sterilization temperature for a certain period of time. , Can be humidified, heated and kept warm. Further, it is possible to raise the temperature of a normal powdery and granular raw material, which is not so difficult for moisture and heat to permeate into the inside, in a shorter time, and similarly humidify and heat the material. Due to this remarkable effect, Salmonella can be reliably sterilized with any powdery and granular raw material having any properties. Further, since the above-mentioned preheating and heat retention can be performed in the fluid mixing container integrally configured, the overall configuration of the device for humidifying and sterilizing the powdery raw material can be dramatically reduced. It can be installed in small and medium-sized feed plants where there is not enough space for installation.

According to the constitution of the invention of claim (3), the constitution of the invention of claim (4), and the constitution of the invention of claim (7), it is possible to sterilize Salmonella bacteria mixed and adhering to the powdery raw material. Powder that has been sterilized by Salmonella in an environment where it can be separated from the external environment by making it slightly higher than the outside air and prevents new invasion of Salmonella adhering to the dust floating in the outside air. Drying and cooling of the granular raw material having a suitable moisture content and temperature for storage can be carried out by using high-temperature air and low-temperature air in which Salmonella does not exist, respectively, and the temperature can be adjusted to a suitable moisture content and temperature for storage. .. In addition, the temperature is slightly higher than the outside air to isolate it from the external environment, and the specified drying and cooling are performed under a transport environment and storage environment that prevent new invasion of Salmonella bacteria adhering to the dust floating in the outside air. The powdery and granular raw material that has been sterilized by Salmonella can be transported and stored. Therefore, a large amount of powdery and granular raw material materials that meet the production plan can be stored in the absence of Salmonella until it is used for the production of the mixed feed.
