The operation of the household food waste disposal device of the present invention configured as described above is as follows.

When the food waste is introduced into the hopper 110 through the inlet 111 of the reactor 100, the heating plate 140 heated by the heating heater 141 located below the hopper 110 is the hopper 110. In this case, the temperature of the heating plate 140 should be raised to about 110 ° C, and the temperature inside the hopper 110 should be about 80 ° C.

In addition, as the internal temperature of the hopper 110 is increased, the moisture contained in the food waste is changed to steam, and at the same time, the stirring impeller 120 is rotated in the forward direction, and the food waste is uniformly dispersed by the stirring blades 122. In this case, when the size of the food waste is more than the appropriate size, it is crushed smaller than the appropriate size by the stirring blade 122 and the crushing blade 113 is rotated to help early drying and decomposition.

In addition, steam generated while the food waste is heated in the hopper 110 of the reactor 100 is introduced into the condenser 200 through the first connecting pipe 910, the steam introduced into the condenser 200 While passing through the cooling pipe 210 installed to pass through the cooling fan 220 of the condenser 200 to generate the cooling air, the temperature is rapidly condensed and separated into condensed water and reduced temperature air, the condensate is activated carbon filter 310 After passing through the final filtration process is discharged to the outside by a predetermined amount through the drain pipe 300, the temperature-sensitive air is pumped to the deodorizer 400 through the second connecting pipe 920 by the blower 600 do.

In addition, the depressed air pumped to the deodorizer 400 is re-warmed by the deodorizing heater 410 to about 300 ℃ deodorizing heater 410 passing through the heat supply pipe of the deodorizer 400 is the deodorizer 400 Deodorized while passing through the platinum catalyst 420 is removed.

In addition, the warm air deodorized while passing through the deodorizer 400 is re-introduced into the hopper 110 of the reaction tank 100 through the guide tube 510 of the air circulation control tube 500 of the reaction tank 100 The hopper of the reaction tank 100 through the intake and exhaust pipe 520 of the air circulation control pipe 500 according to the temperature increase in the hopper 110 and at the same time as the air pressure load in the hopper 110 of the reaction tank 100. The air flowing into the 110 is finely discharged to the outside.

On the other hand, if the above process is continuously repeated, the wet food waste introduced into the hopper 110 of the first reaction tank 100 is decomposed and starts to dry in a state of 0% moisture content in which moisture is completely removed. By-products, the internal temperature of the hopper 110 of the reactor 100, which was about 80 ° C from this point, gradually increases, and when the temperature reaches a preset temperature, the heating heater 141 of the reactor 100 is controlled by the controller 800. ) Operation stops.

Thereafter, when the stirring impeller 120 rotated by the driving motor 130 is rotated in the reverse direction, the stirring blade 122 of the stirring impeller 120 carries the powdered food waste by-products in the hopper 110 of the reaction tank 100. ) It will be discharged to the outside by pushing to the outlet 112 located on the side.

At this time, the opening and closing door 112b of the outlet 112 is automatically opened by the opening and closing motor 112a so that the by-product of the processed food waste is discharged to the outside through the outlet 112, and the treatment When the by-product discharge of the finished food waste is completed, the opening and closing door 112b of the outlet 112 is automatically closed by the opening and closing motor 112a and all the processing processes are automated.

Referring to the temperature control method for the household food waste processor of the present invention configured as described above are as follows.

The heating plate 140 is heated by the heating heater 141 while heating the hopper 110 into which food waste is input and processed, while the heating temperature sensor 820 and the hopper temperature sensor 810 are respectively heated. When the temperature of the plate 140 and the temperature inside the hopper 110 is sensed and displayed, the drying of the food waste that is heat-treated in the hopper 110 is completely evaporated to start the drying in a state where the water content is 0%. As shown in FIG. 1, the temperature of the heating plate 140 for heating the hopper 110 is maintained at a constant temperature, and at the same time, the temperature inside the hopper 110 is gradually increased.

Using this temperature change, it is intended to perform temperature control in which the household food waste processor can be fully automated.

First, when food waste is put into the hopper 110, the controller 870 is a heating heater 141 of the reaction tank 100, a deodorizing heater 410 of the deodorizer 400, a blower 600, a condenser ( The cooling fan 220 of the 200, the drive motor 130 of the reaction tank 100 is operated to start a drying operation, at this time the temperature in the hopper 110 and the heating heater 141 of the reaction tank 100. The temperature of the heating plate 140 and the deodorization temperature of the deodorizer 400 are heated by the hopper temperature sensor 810, the heating temperature sensor 820, and the deodorization temperature sensor 830, respectively. (ST001) (ST002) (ST003)

The comparator 860 receives the temperature value of the heating plate 140 from the heating temperature sensor 820 and the allowable temperature value of the heating plate 140 which is about 110 ° C. previously stored in the set temperature storage unit 850. When the heating plate 140 does not reach a predetermined temperature, the controller 870 continuously operates the heating heater 141 to adjust the temperature of the heating plate 140 to about 110 ° C. When the temperature of the heating plate 140 reaches a predetermined temperature of about 110 ° C., the controller 870 stops the operation of the heating heater 141 to maintain the temperature of the heating plate 140. It is kept constant at about 110 ℃. (ST004) (ST005)

At this time, the temperature inside the hopper 110 by the hopper temperature sensor 810 is about 80 ℃.

In addition, the comparator 860 receives the temperature value of the deodorizer 400 from the deodorization temperature sensor 830, the allowable temperature of the deodorizer 400 is about 300 ℃ stored in advance in the set temperature storage unit 850 When the deodorizing temperature of the deodorizer 400 does not reach a predetermined temperature, the controller 870 continuously operates the deodorizing heater 410 to set the deodorizing temperature of about 300. When the temperature of the heating plate 140 reaches a predetermined temperature of about 300 ° C., the controller 870 stops the operation of the deodorization heater 410 to deodorize the deodorizer 400. The temperature is kept constant at about 300 ° C. (ST006) (ST007)

By the above operation, the temperature of the inside of the hopper 110 is dried by the hopper temperature sensor 810 while indicating a predetermined temperature of about 80 ° C. At this time, the moisture of the food waste is completely evaporated and the water content is 0%. When drying is started in a state, as shown in FIG. 5, the heating plate 140 continuously maintains a constant temperature of about 110 ° C. while the temperature inside the hopper 110 has a water content of 0%. Gradually rising change from the time of complete drying is shown.

That is, the temperature of the inside of the hopper 110 is about 80 ℃ by the heating plate 140 maintaining a constant temperature at about 110 ℃, the moisture of the food waste being processed in the hopper 110 is completely When the drying starts to evaporate, the temperature inside the hopper 110 is gradually raised.

Therefore, the comparator 860 receives the temperature value of the heating plate 140 and the temperature value inside the hopper 110 which is raised from the heating temperature sensor 820 and the hopper temperature sensor 810, respectively, and stores the set temperature. The controller 870 compares the temperature value (for example, the deviation temperature value inside the heating plate 140 and the hopper 110 or the temperature value inside the hopper 110) stored in the unit 850 to the controller 870. The controller 870 selectively operates the heating heater 141 when the temperature value inside the hopper 110 stored in the set temperature storage unit 850 is lower than the temperature value in the hopper 110. When the temperature value inside the hopper 110 stored in the set temperature storage unit 850 is equal to or higher than the temperature value in the hopper 110, the operation of the heating heater 141 is stopped. (ST008) ST009)

Thus, the operation of the heating heater 141 and the deodorizing heater 410, which is a heat energy source, is terminated, but the drive motor 130, the cooling fan 220, and the blower 600 in order to quickly discharge the heat inside the hopper 110 to the outside. ) Is maintained for a certain time to perform the deodorizing function by separating the condensed water and air by the cooling fan 220 with the discharge of heat, and by forcing the air to the deodorizer 400 by the blower 600.

To this end, the controller 870 maintains the operation of the drive motor 130, the cooling fan 220, and the blower 600 for the set time counted by the timer 840, and then stops the operation when the set time elapses. All operations will be stopped. (ST010) (ST011)

In addition, after the operation, the controller 870 operates the open / close motor 112a to open the open / close door 112b of the outlet 112, and then reversely rotate the drive motor 130 to stir the stirring impeller 120. The by-products of the processed food waste by the wing 122 is pushed toward the outlet 112 of the hopper 110 to discharge the by-product of the processed food waste through the outlet 112 to the outside. When the by-product of the food waste is completely discharged through the outlet 112, the operation of the opening and closing motor 112a to close the opening and closing door 112b of the outlet 112 to terminate all operations of the household food waste processor. ST012) (ST013) (ST014)

In the food waste treatment apparatus according to the present invention as described above, steam is generated while the food waste is crushed and dried in the hopper of the reaction tank, and the condenser condenses water vapor generated in the hopper of the reaction tank and separates it into condensed water and air. In the deodorizer, the air separated from the condenser is deodorized and resupplied to the reaction tank, and the drain pipe is first filtered as the process of finally filtering and discharging the foreign substances of the condensed water condensed in the condenser continuously to the work setting time. The wet food waste put into the hopper of the reactor is completely dried and decomposed to remain as a byproduct in the form of a powder, thereby reducing the treatment of food waste more hygienically and quickly.

In addition, the food waste processor of the present invention is fundamentally by minimizing the odor generation and high operating costs, which are disadvantages of the existing dry cracker, by eliminating odor by the flow of air discharged to the outside during operation by the circulating reflow method. It has the effect of solving the problem.

In addition, the food waste treatment device of the present invention is stirred while the food waste put into the hopper of the reaction tank during the forward rotation of the stirring impeller evenly dispersed by the stirring blade is dried by the heat medium oil and treated by the stirring blade during the reverse rotation of the stirring impeller By-products of the food waste can be smoothly discharged through an outlet provided on one side of the hopper, thereby improving the convenience of using the device.

Lastly, by controlling the system by judging the complete drying time of food waste near water content of 0% from which water is completely removed according to the temperature change in the hopper of the reaction tank, it has the effect of high-speed processing of food waste and energy saving. It has the effect of providing a fully automated processor that terminates with the machine itself aware of the food waste disposal status, regardless of the dose.
