Food waste discomposition processing device

The present invention relates to a food processing apparatus provided with an improved shaft installation structure and a stirring structure, and more particularly, a series of processes according to the food treatment including crushing, dehydrating, and fermenting food discharged from each home or restaurant. Performed continuously, the food is configured to produce compost or feed, which is a by-product of the final fermentation, and particularly relates to a food processing device configured to improve durability and agitation efficiency by providing an improved shaft installation structure and an improved stirring structure.

In general, food discharged from a home or a restaurant is collected first in an intermediate collection bin installed in a multi-family housing complex, and then the collection vehicle finally collects the food.

In recent years, the foods thus collected are not buried in a landfill, but after the foods are processed through a food processing apparatus, the foods can be used as feed or fertilizer.

By the way, since the stirring rod shaft is installed perpendicular to the reactor in the structure, the lower portion of the stirring rod shaft is always kept locked by food.

Therefore, food is always introduced into the shaft installation structure formed at the bottom of the housing and the lower portion of the stirring rod shaft, and the physical deformation and wear of the lower end of the stirring rod shaft forming the rotating structure is caused by the unauthorized inflow of food. .

As such, when the deformation and abrasion of the stirring rod shaft occurs, durability is remarkably decreased, and thus, the worker has to periodically repair or replace the stirring rod shaft.

In addition, when the stirring rod shaft is rotated to agitate the food contained in the reaction tank, local food agitation is possible, but the overall food agitation is difficult.

Thus, variations in temperature and oxygen in the lower, upper, and middle portions of the reactor occur, and local food decay occurs within the reactor by such temperature deviation, thereby ensuring stable feed or compost through fermentation of the food. Is difficult.

Therefore, there is a need in the art for a new type of stirring structure that can circulate and stir the food contained in the reaction vessel at a time.

Figure 5 shows the overall configuration of the shaft installation structure for a food processing apparatus proposed in Figure 5, in the food processing apparatus proposed as a preferred embodiment in the present invention, shows a planar structure of the fermentation portion, Figure 6 is the present invention In the food processing apparatus proposed in the preferred embodiment in the stirring rod shaft and compressed air blowing structure installed in the fermentation section The action showing the agitation of the food through the state diagram, Figure 7 is a flow diagram of the stirring state of the food through a food processing system for fermentation apparatus proposed in the present invention in its preferred embodiment.

Food processing apparatus (1) proposed as a preferred embodiment in the present invention is basically a hopper portion 10 for providing a storage space for food; Crushing unit 20 for receiving and crushing the food stored in the hopper 10; Dehydration unit 30 for dehydrating the food crushed through the crushing unit 20; And a fermentation part 40 for fermenting the dehydrated food through the dehydration part 30. And between the hopper portion 10 and the crushing portion 20, between the crushing portion 20 and the dehydrating portion 30, and between the dehydrating portion 30 and the fermentation portion 40, respectively, to provide a food transfer function. It is comprised including the conveyance screw part 50 to plan.

In the food processing apparatus 1 according to the present embodiment configured as described above, when food is first supplied to the hopper unit 10, the shredding unit 20 receives the food through the transfer screw unit 50 to shred the food. In this way, the crushed food is supplied to the dehydration unit 30 through the transfer screw unit 50 to remove moisture.

Then, the dehydrated food is supplied to the fermentation unit 40 through the transfer screw unit 50 and fermented for a predetermined time through the yeast, and finally the food fermentation is completed, the yard through the transfer screw unit 50 ( 60), which is used as compost or feed.

On the other hand, in the present invention, in implementing such a food processing apparatus 1, by installing the stirring rod shaft 44 through an improved shaft installation structure to promote the fermentation of food, the stirring rod shaft according to the inflow of food Wear of (44) is prevented.

Referring to the drawing, the fermentation part 40 has a form in which the stirring rod shaft 44 stands up in the reaction tank 41, and an electric motor 44c is installed at the upper end of the stirring rod shaft 44. The stirring rod shaft 44 standing up at 41 is rotated by applying rotational force from the electric motor 44c to stir the food contained in the reaction tank 41.

In this embodiment, by providing an improved shaft mounting structure between the lower portion of the stirring rod shaft 44 and the bottom 42 of the reaction tank 41, the stirring rod shaft 44 of the stirring rod shaft 44 is always kept locked by food. By preventing food from flowing in between the lower part and the reaction tank 41, the problem that the durability of the stirring rod shaft 44 falls by friction with food is eliminated.

In the shaft mounting structure according to the present embodiment, the bottom shaft 42 of the reaction tank 41 is formed to protrude upward, and the shaft rod 42a is disposed below the stirring rod shaft 44 opposite thereto. A shaft shaft (44a) is formed so as to recess the circular shaft groove (44a) of the entry path, the lower part of the stirring rod shaft 44 protrudes to the bottom 42 of the reaction tank 41 through the shaft groove (44a) It is configured to be seated on.

As shown in the drawing, the upper part of the shaft bar 42a is formed to have recessed grooves 42a-a of '∨', and the recessed grooves 44a-a of '∧' are recessed in the shaft grooves 44a opposite thereto. On the other hand, a ball 44b is formed between the '홈' seating groove 42a-a formed in the upper portion of the shaft bar 42a and the '∧' seating groove 44a-a formed in the shaft groove 44a. Is installed, it is possible to smoothly rotate the stirring rod shaft 44 in a line contact state with the shaft 42 (a) through the ball (44b).

As such, when the lower part of the stirring rod shaft 44 is seated on the shaft rod 42a formed by protruding from the bottom 42 of the reaction tank 41 through the shaft groove 44a, the bottom 42 of the reaction tank 41 is formed. The shaft rod 42a is surrounded by the shaft groove 44a formed at the lower end of the stirring rod shaft 44, and thus the shaft rod 42a and the stirring rod shaft 44 protruding from the bottom 42 of the reactor 41 are formed. Between the lower portions of), a shielding structure n of a '∩' type is formed, which is relatively higher in phase than the bottom 42 of the reaction tank 41. At this time, it is preferable to form the interval of the '∩' shield structure (n) formed between the shaft bar (42a) and the shaft groove (44a) at intervals of 2mm to 10mm.

As such, when a shielding structure n having a phase higher than that of the bottom 42 of the reaction vessel 41 is formed between the shaft rod 42a and the lower portion of the stirring rod shaft 44, the reaction vessel 41 is introduced. The phenomenon that the food is introduced into the step is suppressed, it is possible to prevent the physical damage of the lower portion of the stirring rod shaft 44 due to the unauthorized inflow of food.

Figure 4 shows a comparative embodiment of the installation structure of the stirring rod shaft provided in the food processing apparatus according to the present invention.

For example, as shown in FIG. 4, the shaft groove 42a 'is formed in the bottom 42 of the reaction tank 41, and the lower part of the stirring rod shaft 44 enters the shaft groove 42a', thereby allowing the reaction tank ( When the stirring rod shaft 44 of the food processing apparatus is installed in a structure 'n' having a relatively lower phase than the bottom 42 of 41, the food having the property of not going to be caused by its own weight is placed in a reaction tank ( Since it easily flows into the 'n' structure n 'formed with a lower phase than the bottom 42 of 41, wear of the stirring rod shaft 44 is caused by the inflow of food.

However, as shown in the present embodiment, the shield structure of the '∩' type is relatively higher in phase than the bottom 42 of the reactor 41 between the bottom 42 of the reactor 41 and the bottom of the stirring rod shaft 44 ( When n) is formed, the food having the property of not going away due to its own weight is not easily introduced into the '∩' type shielding structure n formed relatively higher in phase than the bottom 42 of the reaction tank 41.

Therefore, in the present invention, when the stirring rod shaft 44 is installed by forming a shield structure of '∩' type higher than the bottom 42 of the reaction tank 41 through the shaft rod 42a and the shaft groove 44a, Food may be introduced into the shaft 42a and the shaft groove 44a by the '-type shielding structure n.

In addition, in the present embodiment, the grease injection holes 42a-b are formed in the shaft rod 42a formed to protrude upward from the bottom 42 of the reaction tank 41, and the grease injected through the grease injection holes 42a-b is formed. (G) enters the '∩'-type shielding structure n formed between the shaft rod 42a and the shaft groove 44a to form an oil film, and thus greases the' ∩'-type shielding structure n. When the oil film is formed by injecting (G), the stirring rod shaft 44 can be smoothly rotated by lubrication of the grease, and the inflow of food is more stably made by the waterproofing and shielding action of the grease (G). Can be blocked.

Meanwhile, in the present embodiment, as shown in FIG. 3, the rod 42a is not integrally formed at the bottom 42 of the reactor 41, and a plurality of outer edges of the bottom 42 of the reactor 41 are formed. A flange mounting hole 42d having a fastening hole is formed, and the bottom plate 42 'having a plurality of fastening holes formed at the edge thereof is formed so that the shaft rod 42a protrudes upward in the center of the flange mounting hole 42d. The shaft bar 42a is formed in the bottom 42 of the reaction tank 41 so that it may protrude.

When the shaft bar 42a is formed on the bottom 42 of the reactor in a flange structure as described above, opening and closing of the flange installation hole 42d formed in the bottom of the reactor 42 is possible through separation of the bottom plate 42 ', and the opening is performed. The stirring rod shaft 44 can be easily advanced in and out of the reaction tank 41 through the prepared flange installation hole 42d.

Therefore, the food processing apparatus 1 according to the present embodiment can secure the entry and exit path of the stirring rod shaft through the flange installation hole 42d formed in the bottom 42 of the reaction tank 41, and further, the bottom plate 42 '. Partial repair of the shaft 42a or the stirring rod shaft 44 is possible through the disassembly and reassembly of the shaft.

In the present embodiment, the collection tank 42b having the drain pipe 42b-a formed at the bottom 42 of the reaction tank 41 is infiltrated, so that the leachate generated during the fermentation of food is collected in the collection tank 42b. It is configured to be collected through the final discharge through the drain pipe (42b-a).

In this embodiment, the air inlet pipe 43 for supplying the air required for the fermentation through the blower 43a to the collection tank 42b for the collection function of the leachate is disposed in communication with each other, The air required for fermentation of the food through the bottom 42 is sufficiently supplied through the blower 43a and the air inlet tube 43.

Referring to the drawings, a heater 43b is provided on the air inlet tube 43, and when the internal temperature of the reaction tank is low, such as winter, the air supplied through the blower 43a is heated through the heater 43b to react with the reactor 41. By supplying into the inside of the reactor, the reaction tank 41 is configured to stably satisfy the air and the temperature required for the fermentation.

Therefore, when the fermentation unit 40 of the food processing apparatus 40 according to the present embodiment receives the food into the reaction tank 41 and then puts a proper amount of yeast, the fermentation of the food is made by the yeast, and the blower ( 43a) supplies hot air or cold air through the air injection pipe 43 to supply oxygen required for fermentation of food.

And, the leachate generated during the fermentation process of the food is collected through the collection tank 42b installed at the bottom, and then finally discharged to the outside through the drain pipe 42b-a.

Meanwhile, the present invention provides an improved stirring structure in which the high-pressure compressed air is periodically ejected to the fermentation part 40 of the food processing apparatus 1 configured as described above so that rapid stirring of the whole food contained in the reaction tank 41 is achieved. I am preparing.

In the improved stirring structure, as shown in FIGS. 2 to 3, a plurality of jet holes 42c are formed radially at the bottom 42 of the reaction tank 41, and high pressure compressed air is blown into the jet holes 42c. It is the form which made the air discharge part supply intermittently supply.

Here, the compressed air discharge part and the filling tank 45 connected to each of the injection port (42c) and the supply pipe (45a) formed in the bottom 42 of the reaction tank 41; A compressor (46) for filling compressed air therein by continuously injecting outside air into the filling tank (45); And a check valve 47 for opening and closing the supply pipe 45a formed between the jet port 42c and the filling tank 45.

As such, when the filling tank 45 is added between the compressor 46 and the blower outlet 42c without directly connecting the compressor 46 and the blower outlet 42c, a high pressure may be used while using a relatively small capacity compressor 46. Since the compressed air of the can be ejected at a time through the blower outlet 42c, it has the effect of greatly reducing the accompanying costs due to the production, it is possible to prevent the occurrence of overload of the compressor.

Referring to the drawings, in the present embodiment, the filling tanks 45 corresponding to each of the plurality of jet holes 42c formed in the bottom 42 of the reactor 41 are individually connected through the supply pipe 45a.

In this embodiment, the distribution pipes 45b are installed between the plurality of filling tanks 45 to interconnect each of the filling tanks 45 in a parallel structure through the distribution pipes 45b, and the compression unit 46 is provided. Continuously injects air into any one of the filling tanks 45, the injected air is uniformly distributed and compressed to each of the filling tanks 45 through the distribution pipe 45b, and as a result, all the filling tanks 45 It is filled with compressed air of uniform internal pressure.

As such, when compressed air having the same pressure is filled in each of the filling tanks 45, each of the ejection openings separately ejects the high-pressure compressed air filled in each of the filling tanks.

Therefore, the fermentation part 40 according to the present embodiment, since it is possible to fill the plurality of filling tanks 45 with high pressure compressed air through the one compressor 46 at the same pressure, the additional cost of the production It has the advantage of being greatly reduced.

Further, since each blowing port 42c formed in the bottom 42 of the reaction tank 41 ejects compressed air of the same pressure at a time, stirring can be made more stable in food.

Meanwhile, in the present embodiment, a timer 47a is installed to collectively control the open / closed state of the check valve 47 by controlling the current supply according to a set time between the check valves 47 installed in the respective supply pipes 45a. Doing.

In this configuration, the operator does not open and close the check valve 47 manually by hand, and each check valve 47 is intermittently opened and closed by a timer 47a, so that the high pressure filled in each filling tank 45 is increased. Since compressed air is blown out at one time through the blower outlet 42c, stirring efficiency and convenience can be further improved.

And the fermentation section 40 of the food waste treatment apparatus 1 according to the present embodiment configured as described above, the compressor 46 is driven in a state in which each filling tank 45 is closed by each check valve 47 When continuous air is continuously injected into the filling tanks 45 connected in parallel through the distribution pipes 45b, each of the filling tanks 45 is filled by distributing high-pressure compressed air through the distribution pipes 45b.

When the check valves 47 are temporarily opened under the control of the timer 47a in this state, the compressed air of the high pressure stored in each of the filling tanks 45 is formed at the bottom 42 of the reaction tank 41. It is ejected at a time through, and the food contained in the reaction tank 41 by the ejected high-pressure compressed air is stirred at a time.

That is, in the present embodiment, the low pressure air injected through the compressor 46 is not continuously supplied to the reaction tank 41, but the low pressure air injected through the compressor 46 is filled in the filling tank 45 to supply high pressure. Compressed air is formed, and this high-pressure compressed air is intermittently blown into the reaction tank 41 to achieve stirring of the food.
