 The present invention relates to a food waste treatment apparatus. More particularly, the present invention relates to a food waste treatment apparatus in which food waste is stirred, pulverized and dried while being continuously moved through a plurality of inclined feed shafts and a plurality of horizontal feed shafts having a screw formed therein.

Conventionally, the food waste treatment method uses a dehydration method, a drying method, a fermentation method, and the like.

 Dehydration can be used in households where small amounts of food waste are discharged by compressing, crushing, or rotating at high speed, but they are less used in restaurants or catering establishments that emit relatively large quantities. In addition, there is a problem of odor and disposal of the dehydrated waste liquid, and most of them are discharged to the sewer without permission act as another source of pollution.

In the drying method, the food waste is dehydrated to remove water and then dried by heating to reduce the volume of the food waste by 80 to 90%. Pretreatment, dehydration (crushing, compression, high speed rotation), drying, deodorization, dust removal are necessary here. Prior to mechanical treatment such as grinding, compression and high speed rotation, it is necessary to remove foreign substances, and a device capable of controlling odor and dust generated during dehydration and drying is needed. To crush food waste is to homogenize to increase the specific surface area to increase heat transfer. The drying method is applied to existing drying techniques such as direct fire, steam and heat exchanger. In the drying method, using a hot air or a heater in the drying tank to heat the internal temperature of the drying tank to a temperature of about 70 ℃ or more to evaporate only the moisture contained in the food waste, rotation of the food waste in the drying tank after rotation While supplying steam to the outside of the drying tank and drying and crushing the food waste by indirect heat at a temperature above 100 ℃, the fermentation tank is equipped with hot air or a heater to set the temperature above 60 ℃ above fermentation and drying. Fermentation and drying, which is the way to make it happen at the same time.

On the other hand, fermentation, extinction, etc. are used to produce the final by-product that can be used as a compost by biologically decomposing and stabilizing the organic material by various microorganisms. The basic principle of the fermentation method consists of producing a final by-product that can be used for composting by decomposing and stabilizing organic substances by various microorganisms. Food waste is converted into humus where organic matter is stabilized by microbial fermenter put into the fermenter, and pathogens are killed by continuous fermentation heat (60-70 ℃) and finally produce dark brown earthy compost. do. Food waste composting device includes fermentation tank, air supply and organic (air volume) control device and temperature measuring device, and is composed of a heating device for smoothing the initial temperature rise and a stirring device for sufficient homogeneous mixing. The extinction method is basically a principle in which organic substances are decomposed in an aerobic state by a microbial fermenter, as in the fermentation method. However, it is characterized by the introduction of an extinction concept that increases the weight loss by more than 90% by fermentation for a long time. Extinction is the basic principle that food waste is decomposed without a volume increase by adding a certain amount of food waste and aeration control agent and microbial fermentation agent to control moisture in a regular composting facility.

Meanwhile, composting technology by microbial fermentation is as follows. The main processes of food waste composting facilities consist of sorting facilities, mixing and fermentation facilities, impurity removal facilities, ripening facilities and odor removal facilities. At the compost fermentation plant, the air blowing and the temperature are maintained at 55 to 60 ° C. while staying for 28 to 30 days, and agitation is performed about 20 times a day with a compost transfer loader. In compost maturation, composting with aeration and stirring produces less than 45% water content. In order to remove the odor generated during operation of the composting facility, the odorous substances generated in the mixing, conveying, screening, and aging process are collected and transferred to the main composting facility, and the odorous materials transferred to the main composting facility are passed through the composting layer by extrusion method. After removal, it is removed by passing through a biofilter (microbial deodorizing phase), which is an odor removal facility.

Composting by drying consists of the process of dehydration and drying of food waste, followed by ripening fermentation process to add water sprinkling and microbial fermenter for fermentation. The drying process primarily dehydrates food waste (75%) by mechanical compression, transfers it to a hot-air drying chamber, blows hot air at 180-250 ℃, and dries more than 80% of moisture. After transferring to the grinder and finely crushed, the water spray and fermentation agent necessary for ripening in the stirrer is added to the storage place and used as a compost. Odor generated in the drying process is sucked into the odor processor through a closed structure to remove.

 Food waste may also be wet pulverized to feed. Livestock farming (duck, pork) as a technology that selectively removes foreign substances from food waste and then crushes them in the presence of water and sterilize them by heating them, or adds organic acids, kills decaying bacteria, and then mixes them with existing feed. It is a technique that is practically applied directly at). Wet feed manufacturing method has the advantage that the production cost is very cheap compared to the dry method, but the selection of foreign substances and the prohibition of the input of spoiled food must be preceded.

Drying feed technology consists of the process of sorting, drying, and crushing uncorrupted food waste, and economically inexpensive drying technology is required. The pulverized mixture is instantaneously dried by stirring with hot air of about 390 ℃ by the fluidized bed drying method in the drying tower, and is packaged after the second milling process using a hammer mill and the final sorting (vibrating body) process. Is supplied. This method is instantaneous high temperature direct drying method of 390 ℃, almost no nutrient destruction without burning, hygienic sterilization by high temperature sterilization and long-term storage with low moisture content.

 Feeding technology by cooking (cooking) is a process to cook food waste at a high temperature (cooking) and then drying, pulverizing and sorting it to prepare a single feed, and the same technology as the method to feed the existing slaughter by-products. This technology first performs washing and dehydration process and then increases the temperature at 90 ~ 110 ℃ for 30 minutes in the stock raising facility to minimize nutrient destruction due to processing. Secondly, it dries at 90 ℃ for 1 hour to improve water content. After lowering below 10%, cool by rotary method and adjust water content to about 6%. Finally, after grinding by using a hammer mill, the foreign body is removed with a vibrating body to be used as a raw material for blended feed, or supplied to a livestock farm and mixed with an existing blended feed.

 The food waste treatment apparatus is enlarged according to the throughput. Households can be small, taking up the volume of a small trash can, but they can reach the size of a single plant to handle large amounts of food waste collected from multiple places. In this case, the optimization of space usage, which makes it possible to dispose of food waste by using the designated space most efficiently, becomes a very important factor in equipment design. In other words, when processing food waste using the same size machine in the same space, it is very important to make the machine to have the best processing efficiency or throughput. In the conventional food waste treatment apparatus, the movement path of the food waste was not optimized. As a result, a device for transporting food waste was not developed to use the given space as effectively as possible, and optimization of space use was not achieved, and the volume of the equipment became larger than the actual throughput, thereby limiting the design of the equipment.

On the other hand, in the conventional apparatus for processing while transporting food waste, there is a phenomenon that the food waste is transported together to be agglomerated and hardened, there is a problem that the food waste is agglomerated harden the treatment efficiency.

The present invention is a food waste processing apparatus that processes food waste in a chamber while constantly transporting food waste, wherein a plurality of inclined feed shafts and horizontal transfer shafts disposed between them are optimized to maximize the amount of food by maximizing a given space. It is an object of the present invention to provide an efficient food waste disposal apparatus that allows waste to be disposed of.

On the other hand, the present invention during the mixing, decomposition, drying, fermentation of the food waste is transported, the water content is reduced with the passage of a constant temperature and time, and the reduced to dry matter (food waste) are aggregated from each other from this time Because it takes a long time to process, the dismantling screw is installed on the horizontal feed shaft that can prevent this phenomenon, so the processing time is short and the quality condition of the dry matter (food waste) is excellent.
