Description

Food waste processor of extinction fermentation method with enhanced heat retention function

The present invention relates to a food waste processor of the extinction fermentation method to enhance the thermal insulation function, more specifically, it is possible to maintain a sufficient and uniform temperature in the fermentation tank 51 by heat conduction and convection together with the heat insulation of the outer case. The present invention relates to a food waste processor of an extinction fermentation method that enhances the thermal insulation function to maximize the effect of fermentation and decomposition with reduction.

In general, each home or restaurant, such as the leftover (food waste) is discharged every day, such residues are used as livestock feed or simply filtered through a strainer and then discarded. These residue treatment methods increase the amount of food waste in the total amount of waste, and if the food waste is not disposed of smoothly, it causes odors and pollutes the surrounding drinking water or air. .

In the example food waste processor shown in FIG. 1, an input door 12 for inputting the residue and an discharge door 21 for removing the residue after treatment are formed on the outside of the main body 10 of the food waste processor made of a heat insulator. The inside of the main body is provided with a fermentation tank 11 for processing the residue and a deodorizer 30 for removing odor generated during the residue treatment process. The fermentation tank 11 is detachably installed in the main body so as to be detachable when removing the residue, or configured to remove the residue through the opening and closing door 22.

Moreover, inside the fermentation tank 11, the stirrer 16 is rotatably mounted, and the residue is decomposed and processed by stirring and fermenting the fermentation agent and the residue added from the outside. The stirrer 16 is rotated forward and backward by receiving a driving force by the electric mechanism 13 by a chain, a timing belt, etc. which are provided in the fermentation tank 11, and the motor 14, such as an AC induction system.

On the other hand, the upper part of the food waste processor is provided with a suction fan 19 and an exhaust fan 19 'for suctioning and discharging the outside air, and the suction fan and the heater 15 installed therein are external when necessary by a kind of fan heater function. Air is introduced into the air, and the exhaust fan 19 ′ deodorizes the gas (including water vapor) generated therein through the deodorizer 30 installed in the exhaust duct 19 and discharges it to the outside.

The motor 14, the heater 15, the suction fan 19, the exhaust fan 19 ′ and the like are connected to the control panel 20 using a microcomputer, so that the operation of the food waste disposal system is controlled by a predetermined procedure or program. It may be configured to be controlled. The control panel 20 also controls the operation of the food waste processor in a sequential or manual operation according to the set operation mode, and receives the input of the temperature sensor 17 and the humidity sensor 18 installed inside the fermentation tank 11. The internal temperature and humidity conditions also control the operation of the food waste processor. One example of the control system is shown in FIG.

After the food waste is put in FIG. 2, the present temperature value and the humidity value from the temperature sensor 17 and the humidity sensor 18 from the time when the input door 12 is closed by the input door sensor (not shown). When the input is input to the microcomputer 20a via the A / D converters 20b and 20c, the heater 15, the motor 14, the suction fan 19, and the exhaust gas are driven through the driving units 20d and 20e according to a predetermined program. It is configured to adjust the temperature and humidity to 20 to 30 ° C. and 40 to 60% by driving the fan 19 ′ and to maintain the optimum fermentation or decomposition conditions of the food waste by intermittently forward and reverse rotation of the stirrer 16. .

However, although the food waste processor of the above-mentioned structure can heat the air sucked by the suction fan 19 by the heater 15 and the suction fan 19 which are fan heaters installed in the upper left, When the installed exhaust fan 19 'is immediately discharged, the heating effect is not only reduced, but only the upper surface of the agitated food waste is heated, so it is not easy to maintain the optimum temperature inside. There is a problem that the loss is large. In addition, the bottom of the fermentation tank 11 is provided with an opening and closing door 22 on one side, so that only a plate heater can be installed locally, and accordingly, it is locally due to local heating by the local heater (not shown). There is a problem that it is not easy to proliferate or increase the activity of the added fermentation agent easily out of the above temperature range.

The present invention is to solve the problems as described above, in the food waste treatment equipment to treat the food waste by stirring, fermentation, decomposition, it is possible to maintain a uniform temperature throughout the fermenter with energy saving, so that the activity and growth of the fermentation agent The object of the present invention is to provide an extinction fermentation food waste treatment system that can be maximized and enhanced thermal insulation function.
