Description

Food waste handler {GARBAGE TREATMENT APPARATUS}

The present invention relates to a food waste processor for rounding the guide shaft to allow the food waste container to be easily coupled to the housing outer cylinder.

Commercially available technologies for food waste treatment include drying method, fermentation method, fermentation and extinction method, and dry fermentation method.

The drying method is simply a method of putting food trash and inserting a hot air or heater to apply a temperature of 80 ~ 125 ℃ or higher to evaporate the moisture contained in the food. It is a technique to dry without sticking to it.

This method is one of the bad methods listed above due to weight reduction, but high power consumption, high temperature treatment, ease of use, excessive use of power consumption, and safety problems solve the water constituting 85% of food waste. Efficiently removed, the most convenient way to reduce the weight of the consumer.

In addition, the drying method increases the apparent density by simply drying the food waste. In order to make these apparent densities large, the mechanical part broken by the stirring blade is inserted.

As a conventional apparatus for drying food waste, one disclosed in, for example, the publication of Korean Utility Model Registration No. 20-0226974 is proposed.

15 is a cross-sectional view of a conventional small residual processor, which will be described with reference to the following.

The prior art of the drying method is a food waste container that performs the residue treatment, a storage outer cylinder equipped with a separation / mounting mechanism stage capable of separating the food waste container, and a heater I that raises the temperature of the food waste container on the top of the door 28 ( 29) is composed of an insulating asbestos cloth surrounding the outside of the outer housing and minimized the heat loss, and is composed of a deodorizing system 32 to help the platinum catalyst deodorizing function by increasing the temperature of the exhaust air by the built-in heater II (33) have.

Open the door 28, put food waste and close the door 28, the electric motor rotates left and right by a set of control boards, deceleration of the gear device connected to it, rotation of the connected crushing rotary shaft 10, connected crushed wing Mixing of the food waste introduced by the rotation of 17 is performed, and at the same time, electricity is supplied to the heater I 29 of the upper door 28 to generate heat. In this case, the heater I 29 generates heat at 150 ° C. under the control of a temperature sensor attached to the heater I 29, and is transferred to the food waste container. In the temperature sensor, the heater I 29 generates heat and adjusts the internal temperature of the food waste container to 100 ° C to 125 ° C.

When the temperature rises in the food waste container, the injected food waste is dried to generate steam. The water vapor is sucked into the air inlet of the deodorization system 32 through the air flow pipe through the air outlet 31 of the food waste container, and the deodorization system 32 The inside is heated to 300 ° C. by the heater II 33 so that the sucked water vapor is dried to the same temperature. The dry air passes through the honeycomb platinum catalyst 23 provided at one end of the deodorizing system 32 to remove odors. The discharged air is sucked into the intake and exhaust fan, mixed with the internal intake air, and completely discharged to the air outlet.

At this time, the intake / exhaust fan continuously discharges the air in the deodorization system 32 so that the pressure inside the deodorization system 32, the air flow pipe 31, and the inside of the food waste container becomes a negative pressure, 30), Install an air inlet to configure the air flow so that outside air continuously flows into the food waste container under negative pressure through the food waste container air inlet, and perform food waste treatment.

In the conventional food waste treatment system as described above, since the exhaust gas such as steam or odor component is burned and deodorized using a high temperature platinum catalyst heater, the high temperature exhaust gas first passes through the deodorization system 32 ( Since the thermal efficiency is good, the intake and exhaust fan is arranged behind the deodorization system 32 so as to pass through the intake and exhaust fan.

By this arrangement structure, the deodorizing system 32 is disposed between the intake and exhaust fan and the receiving outer cylinder to be widened or increased from side to side to become relatively bulky.

In addition, the deodorization system 32 is disposed between the intake and exhaust fan and the housing outer cylinder, not only does not have a replaceable type of lay-out, but also has the trouble of disassembling the body to replace.

In addition, it can be seen from the cross section of FIG. 15 that the housing outer cylinder is not injection molded integrally with the upper plate in contact with the upper door 28 of the main body. Therefore, a process of supporting the housing outer cylinder on the upper plate of the main body is required, and assembling is complicated, and a separate configuration for supporting the housing outer cylinder is required.
