Description

Steam sterilization tank of food waste treatment equipment {STERILIZING TANK BY STEAM FOR FOOD WASTE TREATMENT MACHINE}

The present invention relates to a food waste treatment apparatus, and more specifically, to process food waste and recycle it to feed of livestock such as chickens, ducks, and pigs. The present invention relates to a steam sterilization treatment tank of a food waste treatment device that completely sterilizes harmful bacteria by high temperature steam to produce a higher quality feed.

In the past, the Korean society, which has been the main agricultural society, has traditionally been aware of the recycling of garbage, and has completely digested all the garbage generated in daily life in one household.

In other words, not only the food leftovers after meals, but even a drop of old Chinese water, in which rice is washed to make rice, has been thoroughly managed as food for cattle and pigs.

However, in modern times, the change of living environment consumes a large amount of materials, and the generation of garbage is exploding accordingly. In rural areas, the soil gradually becomes increasingly sluggish and gradually increases as farmers' compost use decreases due to inorganic farming methods such as chemical fertilizers. Rubbish containing harmful chemicals is overflowing.

In particular, the food waste discharged from homes and restaurants contains a large amount of water, so when it is left for a long time, it becomes easy to decay, and in the process of garbage, a large amount of odor and waste water are generated and discharged into the stream as it is. It damages the water environment and seriously pollutes the air during incineration.

In the meantime, the rapid industrialization and urbanization of many people live in the city, so it is impossible to treat food waste in the traditional manner as in the past.

However, the authorities have consistently focused on reducing the amount of landfills, and when looking at how to collect food waste, the government has committed the dumping to drain the water, causing the liquid to flow to the sewers, causing the water pollution to increase. In addition, most of the solid waste is put in a plastic bag and thrown away like general garbage, and the separate collection is performed.

The factor that makes our food waste disposal more difficult than in other countries is that due to our unique food culture in the world, the diet consists of many types of hot water and soups, so that the moisture content of raw garbage is 83%. This is because there is a significant difference from%.

Therefore, it was necessary to process the liquid and solid at the same time to produce high quality livestock feed and safe fertilizer through the separation method and device suitable for our situation.

However, most of the organic waste treatment apparatuses developed so far use a drying method, which requires heating for a long time, so that a large amount of heat loss and a large amount of moisture control agent are required. Feeding may cause fatal salt poisoning, and when fertilized in soil, there is a problem in that pests are intensified due to salt accumulation or decayed bacteria.

In addition, most of the processing apparatus adopting the fermentation method is to install the impeller inside the machine to stir the contents while supplying heat and air to induce natural fermentation.In this case, decaying microorganisms among aerobic thermophilic microorganisms in the fermented product As the series remains, a longer drying time can lead to deterioration, odor, or unsanitary and poor nutrition.

In addition, when fertilizing this product, it contains some organic matter in the soil. Therefore, if the humidity and temperature are adjusted, decaying bacteria that prefer oxygen take the upper hand in the soil, which causes great damage to crops and further decays the soil. There was a problem that caused the desolation of the land by changing.

Various kinds of food waste treatment devices and methods have been developed to prevent the enormous damage caused by the food waste as described above.

First, a device and method for making compost or feed by dehydrating water contained in food waste and adding fermentation bacteria, and second, a device and method for simply dehydrating water from food waste, and third, biting from food waste. Apparatus and methods are known for drying food wastes from which water is removed after the removal thereof.

The above three apparatuses and food waste treatment apparatus and method thereof can reduce the amount of food waste by greatly reducing the volume and moisture of the food waste, but the first apparatus and method and the third apparatus and method Silver treatment cost and the production cost of food waste treatment equipment is expensive, there is a problem that is difficult to use, the second food waste device and its treatment method is a lower cost than the first and third food waste treatment device and the method for practical use. However, due to deficiencies in the processing process and equipment such as the separate collection and processing of foods, food waste may be processed if it contains solid foreign substances such as wooden chopsticks, toothpicks or glass bottles. Not only is this impossible, but the food waste disposal system It had problems such as being touched.

In some cases, many efforts have been made to feed food waste, but most of the food waste is dehydrated immediately after dehydration. There was a problem.

Therefore, in order to collect food waste and recycle it to feed, most foods are organic substances that are highly perishable, and most of them are exposed to the outside air, and there is a high possibility of harmful bacteria propagating, and the feed of recycled foods with a large amount of harmful bacteria remaining. In this case, the livestock may be harmed, so it is necessary to completely sterilize the harmful bacteria remaining in the processed food waste in order to recycle it to the feed of the livestock.
