Description

FOOD REFUGE TREATMENT APPARATUS

Technical Field The present invention relates to a food refuge treatment apparatus, and more particularly, to a food refuge treatment apparatus which quickly dries and decomposes food refuges by indirect heating using a heat medium oil to thereby attain reduction of weight and volume, in which steam generated during performing a dry decomposition passes through a condenser so that only water is discharged out but air is not discharged out, that is, an air circulation recycling method which inputs again air into a reaction vessel is employed, to accordingly little cause a thermal loss and an offensive odor since there is no air to be discharged out, a stepwise electric heater system is used as a thermal energy source to thereby minimize energy of use, a food refuge to be treated is not decomposed so as to be hygienic and used as recycled resources such as organic fertilizers, a running cost is minimized by shortening a treatment time with a low energy and an efficient running mechanism, a safety device is attached to assure a safety and contrive convenience of use, noise and vibration is minimized, and the food refuge treatment apparatus is small in size to thereby minimize an installation space. Background Art In general, conventional food refuge treatment systems are classified into a fermentation system, a fermentation extinction system, a screw compression dehydration system, a piston compression dehydration system, a dehydration drum rotation centrifugal dehydration system, a heating drying system, a burning system, and a combination thereof. The fermentation system and the fermentation extinction system use microbes, and thus are unhygienic . Since their machines are large in comparison with a capacity of treatment, they occupy large space for installation. Further, their system prices are expensive, treatment times are long, management of microbes is difficult, and peripheral environmental pollutions occur due to occurrence of severe offensive odor during fermentation. It inconveniences to use them. The compression systems such as the screw compression dehydration system and the piston compression dehydration system cause severe pollution of waste water due to compression and dehydration. Since it is not easy to remove, clean or hygienically treat leftovers remaining in a dehydration filter, the leftovers are decomposed and accordingly stinks offensively. As a result, it is not so simple to solve these drawbacks. Further, since a food refuge to be treated has a high percentage of moisture content, a weight reduction rate is low. It also causes inconveniences of using them. The dehydration drum rotation centrifugal dehydration system has merits such as a speedy treatment time and a small amount of energy consumption, but it is not easy to remove, clean or hygienically treat leftovers remaining in a dehydration hole. It also causes inconveniences of using it. Like the compression system, it causes water pollution. Also, since a food refuge to be treated has a high percentage of moisture content, a weight reduction rate is low. As a result, it needs a secondary treatment . Thus, decomposition and offensive odor occur due to negligent management to thus cause an environmental pollution again. Further, the heating drying system uses electricity or fuel, to accordingly consume excessive energy to dry food refuges, and causes severely offensive odor, to thus cause a bigger problem of treating the offensive odor. Its treatment time is long, which impedes stability of the system and shorten the life of the system. Further, the burning system burns a food refuge directly, and produces a noxious gas such as dioxin due to imperfect combustion according to a large machine and a low heat generation power. Since it also consumes excessive energy, it greatly influences upon stability of the system and a peripheral environment of the system, which causes a difficulty of using it. Disclosure of the Invention To solve the above problems, it is an object of the present invention to provide a food refuge treatment apparatus which uniformly distributes food refuges by a stirrer and dries the distributed food refuges, and simultaneously crushes the food refuges into small pieces by a crusher so that the food refuges are decomposed, in which steam generated during performing a dry decomposition passes through a condenser so that only water is discharged out but air is not discharged out, that is, an air circulation recycling method which inputs again air into a reaction vessel is employed, to accordingly little cause a thermal loss and an offensive odor since there is no air to be discharged out, and to thus have no sewage pollution due to an artificial compulsive dehydration and no air pollution due to a burning by heating, and effectively accomplish shortening of a treatment time and reduction of weight. It is another object of the present invention to provide a food refuge treatment apparatus in which thermal energy consumption is very small due to use of a stepwise electric heater system and an efficient running, the number of trouble-making elements is few to thereby assure a stability of the system, a small space for installation is required and a running cost is small, to thus provide a low price and a wide distribution of the apparatus ..

Here, one support frame 210 is connected with and communicates with the hopper 110 in the reaction vessel 100 by a connection tube 240 so that steam generated when food refuges are heated in the reaction vessel 100 passes the support frames 210 and the cooling pipes 220 via the connection tube 240, and contacts the cold air so as to be condensed and separated into water and air. The deodorizer 300 includes a heat supply tube 310 having a guide hole 311 therein, a catalyzer tube 320 which is sequentially connected with the heat supply tube 310 to communicate with the heat supply tube 310, at least one electric heater 330 which is fixedly disposed in the heat supply tube 310, and a thermal anti-aging ceramic carrier 350 and a number of platinum catalyzer layers 340 which are fixedly disposed at regular intervals in the catalyzer tube 320. Here, the heat supply tube 310 is connected with and communicates with the other support frame 210 in the condenser 200 by a connection tube 360, and the catalyzer tube 320 is connected with and communicates with the hopper 110 in the reaction vessel 100 by a connection tube 370. The deodorizer 300 also includes a cooling air discharge tube 380 which is connected with and communicates with the connection tube 370 so that the catalyzer tube 320 is connected with and communicates with the hopper 110 in the reaction vessel 100, to thereby deodorize air having passed through the condenser 200 while passing through the heat supply tube 310 and the catalyzer tube 320, to make hot air having passed through the heat supply tube 310 and the catalyzer tube 320 re-input into the reaction vessel 100 via the connection tube 370 to thus raise temperature in the reaction chamber 111 and simultaneously discharge air via the cooling air discharge tube 380 minutely if an air pressure load occurs in the reaction chamber 111.

The air blower 400 is installed on the connection tube 360 which connects the condenser 200 and the deodorizer 300, and sends air having passed through the condenser 200 to the deodorizer 300. The automatic drain tube 500 includes a drain vessel 510 which is connected with and communicates with the drain cock 212 formed in the lower portion of the support frame 210 in the condenser 200, a number of fibriform active carbon layers 520 which are disposed in ^"multiple layers in the drain vessel 510, and a water discharge tube 530 formed in and communicating with the lower side of the drain vessel 510, so that condensed water generated in the condenser 200 is finally filtered and drained while passing through the fibriform active carbon payers 520. As shown in FIG. 3, the stirring impeller 130 in the reaction vessel 100 includes a shaft axis 131 which is horizontally rotatably disposed in the reaction chamber 111 of the hopper 110 and a number of stirring wings 132 which are radially fixedly combined around the shaft axis 131 by rotational arms 133. Also, a sprocket 152 is fixedly combined with the shaft axis 131 and the driving axis 151 of a driving motor 150, respectively. The sprocket 152 is combined with a chain 153 so as to be operated together with the chain 153, so that the stirring impeller 130 is rotated according to driving of the driving motor 150. The driving of the driving motor 150 is controlled by a controller 600 according to a food refuge treatment time in the reaction vessel 100. As shown in FIG. 3, the stirring wings 132 each include a stirring piece 132a and an inclined piece 132b formed on the rear portion of the stirring piece 132a, which push and stir food refuges and are integrally combined with each other with a slope of a predetermined angle. The inclined pieces 132b are symmetrically formed with each other around the center portion of the shaft axis 131. If the shaft axis 131 rotates forwards, food refuges are pushed by the stirring pieces 132a in the stirring wings 132 and uniformly distributed and stirred at both end directions of the shaft axis 131, and if the shaft axis 131 rotates backwards, food refuges are pushed by the inclined pieces 132b in the stirring wings 132 and collected into the center portion of the shaft axis 131. In this case, it is preferable that the outlet 113 which discharges the treated food refuges from the reaction chamber 111 is positioned in the middle portion of the shaft axis 131 at which the food refuges are collected by the stirring wings 132. As shown in FIG. 2, the stirring wings 132 in the stirring impeller 130 and the crusher 140 is fixedly combined on the inner wall of the reaction chamber 111 in the hopper 110 are installed mutually adjacent each other, so that food refuges are cut and crushed between the rotating stirring wings 132 and the crusher 140. The heating portion 120 formed of a double vessel structure is integrally formed with the hopper 110, so that a heating frame 121 having a heating chamber 121a surrounds the lower portion and the side portion of the hopper 110. The electrically operated heater 122 is horizontally disposed in the heating chamber 121a within the heating frame 121, and the heating chamber 121a is filled with the thermal medium oil 123 so that the hopper 110 is indirectly heated by the thermal medium oil 123 while the thermal medium oil 123 is heated by the heater 122. Power consumption in the heater 122 of the heating portion 120 is minimized by employing a stepwise power supply method. According to the stepwise power supply method, maximum power is supplied initially to heat the thermal medium oil 123 quickly so that temperature in the reaction chamber 111 quickly rises up, half the initial power is supplied to the heater 122 in the thermal medium oil 123 to heat the reaction chamber 111 until temperature in the reaction chamber 111 reaches about 80^°C, and quarter the initial power is supplied to the heater 122 in the thermal medium oil 123 if the temperature in the reaction chamber 111 reaches about 80 ^°C to maintain the temperature in the reaction chamber 111 into about 80^°C so that electric energy consumed in the heater 122 up to the end of heating is minimized. In an experimental result, according to the stepwise power supply method, power is initially supplied at 4K for thirty minutes, secondarily at 2KW for twenty minutes, and finally at 1K until completion of the work. A temperature detection sensor 160 is installed in the hopper 110 of the reaction vessel 100, and the heater 122 is controlled by a controller 600 according to a signal supplied from the temperature detection sensor 160. A thermal medium auxiliary tank 170 is installed on the side of the hopper 110 so that a thermal medium oil 123 is thermally expanded by the heater 122 in the heating portion 120. Thus, pressure in the thermal medium auxiliary tank 170 rises up to a certain pressure level, to accordingly enable an expansion valve 171 to be automatically opened and closed to discharge out the inner pressure. The cooling pipes 220 in the condenser 200 include a number of cooling wings 221 on the outer portion thereof in order to widen an external contact area and thus give a great heat transfer effect to the cooling fan 230 so that condensing of vapor passing through the cooling pipes 220 is performed more efficiently. Here, the platinum catalyzer 340 in the deodorizer 300 is formed by coating platinum on a honeycombed ceramic surface. The driving motor 150 rotates forwards and backwards. The chain 153 which gives the driving force of driving motor 150 to the stirring impeller 130 maintains the tensile force thereof by means of a chain adjustment gear 154, and the electric heater 330 in the deodorizer 300 includes a number of radiation wings 331 in order to widen an external contact area and thus raise temperature of the inner air incoming to the air blower 400 by the electric heater 330 and maintain temperature in the heat supply tube 310 into a proper temperature so as to move to the catalyzer tube 320. The electric controller 600 includes a running hour manipulating panel 601, and a failure lamp 602 which informs a user of a failure or a mechanical stop at an overheat and overload. A power switch 603 receives primary input power. A running switch 604 is pressed to automatically run all functions until a work is completed. A discharge switch 605 is pressed to discharge the final products externally. A stop switch 606 initializes the mechanical functions after the final products have been completely discharged. The function of the food refuge treatment apparatus having the above-described structure will be described below. If food refuges are input into the reaction chamber 111 of the hopper 110 via an inlet 112 formed in the reaction vessel 100, the moisture contained in the food refuges is changed into vapor since temperature in the reaction chamber 110 rises up to about 80^°C by the heating portion 120 positioned in the lower portion of the hopper 110. Simultaneously the stirring impeller 130 rotates forwards, and thus the food refuges are uniformly distributed by the stirring pieces 132a in the stirring wings 132. Here, in the case that size of the food refuges are larger than a proper size, the food refuges collide between the rotating stirring wings 132 and the crusher 140, and crushed into pieces a proper size or smaller, to then assist an early dry decomposition . The vapor generated in the food refuges by the heater 122 in the heating portion 120 within the reaction chamber 111 of the reaction vessel 100 is input to a condenser 200 via a connection tube 240. The temperature of the vapor input into the condenser 200 is abruptly lowered by an air blowing fan 230 in the condenser 200 while passing through a plurality of cooling pipes 220 and condensed and separated into water and air. The water is input into an automatic drain tube 500 via a drain cock 212, and the cold air is forcedly sent to the deodorizer 300 by the an air blower 400 via the connection tube 360. The condensed water supplied to the automatic drain tube 500 via the drain cock 212 is finally filtered whole passing through the fibriform active carbon layers 520 and discharged via the discharge tube 530. The air forcedly sent to the deodorizer 300 by the air blower 400 via the connection tube 360 is re-heated up to temperature of about 300-350^°C by the electric heater 330 while passing through the heat supply tube 310 in the deodorizer 300. The re-heated air is deodorized while passing through the thermal anti-aging ceramic carrier 350 and a number of platinum catalyzer layers 340 in the catalyzer tube 320 of the deodorizer 300. The hot air is re-input into the reaction vessel 100 via a T-shaped connection tube 370, to assist temperature in the reaction chamber 111 to rise up. Meanwhile, in the other side of the T-shaped connection tube 370, air is discharged via the cooling air discharge tube 380 minutely if an air pressure load occurs in the reaction chamber 111. Meanwhile, the above-described process is repeatedly performed, the wet food refuges initially input into the reaction vessel 100 is completely dried and decomposed, having powder shaped remnants remain. Then, if the stirring impeller 130 which is rotated by the motor 150 is rotated reversely, the inclined pieces 132b formed in the stirring wings 132 of the stirring impeller collect the powder shaped food refuges into the direction of the outlet 113 positioned in the middle portion of the shaft axis 131, so that the treated powder shaped products can be smoothly discharged via the outlet 113 in the reaction vessel 100.

Industrial Applicability As described above, the food refuge treatment apparatus according to the present invention provides an effect of treating food refuges more hygienically, and reducing the weight of the food refuges more quickly. In the reaction vessel, food refuges are crushed and dried to generate vapor. In the condenser, the vapor generated in the reaction vessel is separated into water and air. In the odorizer, the air separated in the condenser is deodorized to then be re-supplied to the reaction vessel. In the active carbon filter, the condensed water condensed in the condenser is finally filtered to remove and discharge out foreign matters from the condensed water. In the case that the above-described processes are repeated up to a work set time, the wet food refuges initially input into the reaction vessel is completely dried and decomposed to thereby have powder shaped remnants remain. Also, the food refuge treatment apparatus according to the present invention employs a stepwise power supply method and an air circulation re-input method. According to the stepwise power supply method, the heater in the heating portion which heats and dries food refuges input into the reaction chamber of the reaction vessel is run with minimum energy. According to the air circulation re-input method, air is re-input into the reaction vessel. As a result, since air is not discharged during running, no offensive odor and thermal loss exists. Thus, the food refuge treatment apparatus according to the present invention provides an effect of minimizing generation of the offensive odor and the running cost which are defectives of the conventional dry decomposer of food refuges. Also, the food refuge treatment apparatus according to the present invention uniformly distributes and stirs food refuges input into a reaction chamber in a reaction vessel by a number of stirring wings during forward rotation of a stirring impeller and dries the food refuges by a heating portion. Meanwhile, the food refuge treatment apparatus collects the treated food refuges in the central portion by the stirring wings during backward rotation of the stirring impeller, to thereby smoothly discharge the powder shaped food refuges via an outlet and to thus enhance convenience of use of the apparatus. As described above, the present invention has been described with respect to particularly preferred embodiment. However, the present invention is not limited to the above embodiment, and it is possible for one who has an ordinary skill in the art to make various modifications and variations, without departing off the spirit of the present invention.
