The present invention relates to a food waste treatment machine, and more particularly, to achieve high-temperature dry decomposition of plant waste by indirect heating using heat medium oil, thereby achieving a goal of weight loss and reduction, and passing steam generated during dry decomposition to a condenser. It adopts the air circulation recycling method that only pure water is discharged and does not discharge the air to the inside of the reactor, and there is no air discharged to the outside, so there is almost no heat loss and no odor is generated. The use of electric heater system is minimized and the processed materials are not decayed, so they are recycled and used as sanitary and organic fertilizers, and the operation time is minimized by reducing the processing time with low energy and efficient operation structure, and by attaching safety devices. Ensure safety and ease of use, minimize noise and vibration And the machine will be reduced on the garbage disposal to meet any and all requirements such as minimal installation space.
In general, food waste is classified into treatment methods such as fermentation, fermentation, screw compression and dehydration, piston compression and dehydration, dehydration drum, rotary centrifugal dehydration, heat drying, and incineration. There are complex ways.

In addition, in the crimping method, such as screw crimping and piston crimping, the contamination of sewage by crimping and dehydration is severe, and food waste is spoiled because it is not easy to remove and wash or sanitize the debris caught in the dewatering filter, which causes additional odor. Because of this, it is not easy to solve the problem and the water content is high in the treatment, there is a problem that it is inconvenient to use the low loss rate.
In addition, dehydration drum rotational centrifugal dehydration has the advantages of fast processing time and low energy consumption, but it is easy to use because it is not easy to remove and clean the debris stuck in the dehydration hole. Silver water content is high, the weight loss rate is low, the secondary treatment is required, if neglected management, there was a problem that causes pollution again due to corruption and odor.
In addition, the heat-drying method requires hot air drying using electricity or fuel, so excessive energy is consumed and severe odors cause more problems in its treatment, and the processing time is long and the safety and machine life are short. There was a problem.
In addition, incineration is a direct process of the processed material, and due to the large size of the machine and incomplete combustion due to low calorific value, it is necessary to generate harmful gases such as dioxins, consume excessive energy, and have a great influence on the safety of the device and the surrounding environment.

It is smallly crushed and decomposed, and only the pure water is discharged by passing steam through the condenser, and by adopting the air circulation inflow method, which introduces air back into the reactor, there is almost no heat loss and no heat loss. Not only does it occur at all, there is no pollution of sewage caused by artificial forced dehydration, no air pollution by heating incineration, and it effectively achieves treatment time and reduction effect. Energy consumption is very low, and there are few failure factors, , The maintenance cost was minimal installation space, reduced operating a burden almost no rain to provide an inexpensive garbage disposal.
