A discharge port 35 for discharging the steam generated from the raw material is installed on the upper side of the fermentation tank 30, the drain pipe 38 for discharging the leachate generated from the raw material is installed on the lower side of one side of the fermentation tank 30. Unexplained sign. TI stands for Thermometer, PI stands for Pressure Gauge, TC stands for Temperature Controller, TIC stands for Thermostat, and LS stands for Water Level Sensor.

Figure 2 is a perspective view showing a detailed configuration of the fermenter according to the present invention.

The fermentation tank 30 of the present invention attaches the outer wall plate 36 to the outside of the case 30 'to form a jacket, which is an independent space, and allows steam to circulate through the connection ports 33 and 34. The plurality of U-shaped supports 37 interposed between the case 30 'and the outer wall plate 36 reinforce the strength and distribute and flow the water vapor so as to evenly distribute the temperature in the fermentation tank 30. Reference numerals 33 and 34 Since each is connected to the water vapor supply means to be described later as a connection port for the introduction and discharge of steam, steam introduced to both sides of the fermentation tank 30 passes through the jacket and discharged to the lower end and continuously circulated.

On the other hand, the front surface of the fermentation tank 30 including such an outer wall plate 36 is preferably attached to the heat insulating material to reduce the heat loss.

3 is a configuration diagram showing an enlarged stirrer according to the present invention, referring to FIGS. 1 and 3, the stirrer 20 of the present invention rotatably accommodated in the fermenter 30 is provided from the outside. It is connected to receive the driving force of the reduction motor (15). The reduction motor 15 is preferably multi-stage adjustable, it is preferable to use an electric method that can prevent overload.

The stirrer 20 first fixes the single rods 22 and the long rods 23 at right intervals on the axis of reference numeral 21 at regular intervals, and uses the single rods 22 and the long rods 23 to form a narrow inner blade 24. The wide outer blade 25 is joined to alternately cross. Here, the width means the size seen in the radial direction of the shaft 21, that is, the vertical direction in FIG. The scraper 26 is alternately bonded to the up-down symmetrical position on the outside of the outer blade 25, the outer blade 25 and the scraper 26 is the same width up and down. The scraper 26 maintains a minimum gap with the inner surface of the case 30 'forming the fermentation tank 30 to prevent the raw material from adhering to and solidifying the inner surface. Solidification of the raw material may overload the agitator 20 to increase power consumption and cause damage to the shaft 21. The scraper 26 also serves to prevent the finished product from being completely discharged.

In this way, the raw material introduced to the center point by the inner blade 24 and the outer blade 25 is crossed in a ribbon shape is distributed and transferred to both sides in the upper direction of the shaft 21 by the inner blade 24 and the outside It causes the circulation action of gathering from the lower direction of the shaft 21 to the center by the wing 25 again. Since the scraper 26 for vertical inversion is merged with the ribbon structure for the left and right conveyance, it is advantageous to disperse the action force to prevent breakage of the shaft 21 and to optimize the mixing and decomposition of the raw materials.

Figure 4 is a perspective view showing in detail the drain pipe structure according to the present invention.

The drain pipe 38 of the fermentation tank 30 is piped to receive a portion of the water vapor from the header 43 and has a gate valve 39 upstream of its connection point. Since the drain pipe 38 is clogged as a part of the raw material is discharged in addition to the leachate, a configuration for coping with this is necessary. Reference numeral 38a denotes a pipe for branching part of the water vapor from the header 43. If the leachate is not discharged smoothly, the gate valve 39 is turned on to shut off the drain pipe 38 and the valve is temporarily opened on the pipe 38a so that the high pressure steam releases the blockage of the pipe. To turn off the discharge of leachate into the drain pipe (38).

In addition, referring to FIG. 1, the present invention condenses water vapor discharged from the fermentation tank 30 in the condensation tanks 41 and 42, heats the boiler 40, and branches from the header 43 to fermentation tank 30. Use steam supply means to circulate in the furnace. The condensing tanks 41 and 42 are installed at appropriate capacities to improve the efficiency of the boiler 40, and each pump and level sensor are installed as shown in the figure. The downstream condensation tank 42 is connected with a pipe for supplying water from the outside. The header 43 receives steam from the boiler 40, supplies it to the fermentation tank 30, the drain pipe 38, and the drying hot air fan 50, and sends the excess to the condensing tank 41 on the upstream side. On each pipe, a manual valve, a pressure reducing valve, a solenoid valve, or the like is mounted as shown by a pipe symbol in the drawing. The solenoid valve is turned on / off by a signal from the controller indicated by the symbols TI and TIC.

At this time, the water separator 44 is installed in a part of the pipe of the steam sent from the header 43 to the fermentation tank 30 to generate pure water vapor and to be directly supplied to the raw material in the fermentation tank 30 to improve the decomposition and sterilization effect. . Since the pure water vapor is increased and decreased by a solenoid valve installed on the pipe with a temperature controller of the code TC, it is possible to control the proper temperature and humidity inside the fermentation tank 30. As shown in FIG. 1, it is advantageous to reduce the burden on the separator (44) and to miniaturize using water vapor that is circulated to the jacket of the fermentation tank (30) or sent to the drain pipe (38).

In addition, in the present invention in FIG. 1, the header 43 receives a part of steam and uses it as a heat source, and uses a drying hot air blower 50 for sending external air passing through the heat source to the fermentation tank 30. Water vapor passing through the drying hot air fan 50 in the header 43 is sent to the condensing tank 41 on the upstream side. A plurality of dampers are provided on the piping ducts of the drying hot air fan 50 and the fermentation tank 30 to block excessive flow of air.

5 is a perspective view showing in detail the drying hot air fan according to the present invention. The drying hot air fan 50 of the present invention has a fin tube 51 through which water vapor, which is a heat source, circulates, a filter 52 for filtering external air, and a blower fan 53 for forced air supply, and the plurality of branching holes dispersed therein. Pipe (54) is connected to the fermentation tank (30). Fin tube 51 has a large heat transfer area so that the air is heated quickly. The branch port 54 is wider toward the lower side, and a lattice of code 54a is installed in the middle so that hot air is evenly sprayed into the fermentation tank 30. In FIG. 1, the blower fan 53 is provided with a temperature controller of code TC to be automatically turned on / off at a set temperature.

As such, the drying hot air uniformly sprayed into the fermentation tank by the drying hot air fan 50 flows into the jacket of the fermentation tank 30 and maintains the proper temperature and moisture required for fermentation together with steam which indirectly heats the inside of the fermentation tank 30. To facilitate. Hot air removes some of the moisture generated during the fermentation process and prevents condensation on the fermentation tank 30.

An example of operation according to the present invention will be described with reference to FIGS.

When the water vapor reaches a predetermined temperature and pressure by operating the boiler 40, the reduction motor 15 is turned on to feed the raw material into the fermentation tank 30 while rotating the stirrer 20. When the boiler 40 maintains the maximum pressure (for example, 7 atm) while the steam pressure of the jacket is maintained at approximately 4 atm, the pipe of the jacket is locked and the separator 50 is opened to sterilize and disintegrate into dry high pressure steam. Ripening) action, the device of the present invention can maximize the efficiency of mixing, crushing, sterilization, decomposition by continuous maintenance of the appropriate temperature (70 ~ 80 ° C).

Although it depends on the physical properties of the raw material, when the sterilization and decomposition action for approximately 20 to 30 minutes is completed, the supply of steam to the jacket is resumed and microorganisms are introduced as necessary. The hot air of the drying hot air fan 50 is sprayed 30 to 40 minutes before the end of the operation. The time at this time depends on the physical properties of the raw material and is appropriately set using a timer. About 2.5 to 3 hours after the input of raw materials, the sweet rice and fermented feed are completed. At this time, the boiler 40 is stopped and the outlet 32 of the fermentation tank 30 is made available to the operator by using various alarm means. Is opened. When the feed is completely discharged from the fermentation tank 30, hot air of the drying hot air blower 50 is blocked and the stirrer 20 is also stopped. This series of processes is easy to fully automate as a kind of sequence control.

On the other hand, the feeder of the present invention can also be used as a food processor, a sweet rice feeder, a condensed powder dryer, a feed mixer.

The structure of the fermented feeder of the present invention having the above structure and action is a highly efficient and highly efficient process that prevents the deterioration of the feed through the process of adding, mixing and fermenting microorganisms to food waste, pig and poultry, and by-products of the food factory. It has the effect of being performed.

In other words, it is possible to obtain the effects of mixing, crushing and sterilizing by continuously maintaining the proper temperature, and to prevent the deterioration or nutrient destruction due to overheating. Since facility maintenance is very good, eliminating toxic elements, the intake can be increased by improving the digestibility and palatability of feed products due to the activity of useful microorganisms.

In addition, since the fermentation is completed within a short time, the burden on both farmers can be reduced with high efficiency and low cost while reducing labor force. In addition, by using reuse and regeneration methods, the amount of waste that is discarded is reduced, thus helping to solve the shortage of landfills.
