Description

Food wastes cutting dryer

The present invention relates to a food waste crushing dryer that removes water from food waste, crushes and dries it, and reduces its volume and weight so that it can be easily transported and disposed of or recycled. It is about to discharge by drying with hot air.

In general, since food wastes contain a lot of moisture, they are not only heavy, but also bulky and odorous, making it difficult to dispose of them. Recently, these food wastes are collected separately from other wastes, and then crushed and compressed. In many cases, it is reprocessed by dehydration, fermentation, drying, and recycled as fertilizer or feed.

However, since conventional food waste reduction facilities or recycling facilities are large in size and occupy a lot of processing work or operating space, only a few large companies with large workplaces can install and operate them, so that they can be installed in ordinary homes or small restaurants. There was a problem in that there was no way to reduce waste disposal.

Therefore, in the conventional homes and small restaurants, there were many examples of removing only water from food waste collected separately from general waste and putting it in a food waste container managed by a recycling company or putting it in a general garbage bag.

The present invention has been devised in view of the above-described conventional situation, and its purpose is to easily grind and dry food waste in a general home or a small restaurant so that it can be quickly reduced in small volume and small weight, and of course, weight loss. It is to provide a food waste crushing dryer that allows the processed food waste to be recycled as feed or fertilizer.

The food waste W is crushed and dried.

When the grinding electric motor 21 is operated for a predetermined time, the rotary disk 23 connected to the rotary shaft 21a rotates at high speed, and the rotary blade 23a installed on the upper surface of the rotary disk 23 is rotated. As the food waste W is crushed finely, it is scattered by centrifugal force and attached to the inner walls of the pulverization tank lower body 20a and the upper body 20b provided with the protection net 26a.

Moisture generated during the grinding process and flowing along the inner wall of the lower body 20a is accumulated in the concave bent portion 27 provided at the lower end of the lower body body 20a, and flows into the falling hole 28a of the support ring 28. The falling water is accumulated in the concave portion 25b through the falling space 25a and the strainer 25c of the motor housing 25, and is crushed through the rotary blade 23a to be attached to the inner wall of the lower body 20a. The food waste W remaining therein and the moisture generated therefrom and accumulated in the concave bent portion 27 of the lower body 20a are heated by hot air supplied by the blower fan 31 and the heating heater 24. And dried, and the water falling into the drop space 25a of the motor housing 25 is dried and extinguished by the heating heater 24 provided around the motor housing 25.

On the other hand, in the above pulverization and drying process, food waste (W) and water finely pulverized by each electric heater 24 operated for a predetermined time by the electric heater heater 12 are dried, and the dried food waste ( W is in the state attached to the inner wall of the lower body 20a and the upper body 20b in which the protection net 26a was installed.

And the food waste (W) attached to the inner wall of the lower body (20a) while the primary grinding and drying in the grinding tank 20 is a scratcher (26s) protruding to the outside of the case 10 When the 26 is rotated, the scratcher 26 scratches the inner wall of the lower body 20a so that the scratcher 26 falls down, and the small particle food waste W falling from the inner wall of the lower body 20a is sealed. Through each of the drop holes 28a of the 28, it falls into the drop space 25a of the motor housing 25.

On the other hand, the food waste W accumulated in the drop space 25a of the motor housing 25 is a new food waste W introduced into the grinding tank 20 by the operation of the crushing electric motor 21 and the rotating disc 23. ) Is pulverized and is transferred to the connecting pipe 35 by the rotary feed blade 23c provided at the lower end of the rotating disc 23 to fall into the stirring body 34 of the stirring / fermentation tank 30.

Food waste (W) entered into the stirring body (34) is connected to the stirring electric motor 32 is fermented while being stirred by a rotating stirring rod 33 and its stirring blade (33a), the grinding tank ( Appropriate moisture flows through the connection pipe 22a connected to the steam outlet 22 of 20), and is heated to an appropriate temperature by hot air supplied from the pulverization tank 20, so that secondary drying and fermentation can be performed more efficiently. Will be.

And the food waste (W) is secondary drying and fermentation in the interior of the stirring body 34, the storage tank 40 through a plurality of discharge holes (34a) provided in the lower central portion of the stirring body 34 in the process of drying and fermentation Falling to, the storage tank 40 is open to the opening and closing door 15 is provided in the front of the case 10 can be withdrawn to the outside to discard or compost.

On the other hand, the ozone generator 51 installed in the internal exhaust communication 37 of the stirring body case 36 neutralizes the smell of the food waste W generated in the drying and footing well, and the internal air of the case 10 Odor is removed by the exhaust side of the internal exhaust communication 37 and the carbon filter 53 installed in the exhaust fan 52 in the process of being discharged to the outside through the exhaust fan 52 in a clean state The bar can be discharged. In the present invention, if an air cleaner or the like is installed at one side of the exhaust fan 52 drawn out of the case 10, the discharge air can be purified more clearly.

Meanwhile, in the present invention, as illustrated in FIG. 6, the stirring body 63 is installed in the storage tank 40 installed at the lower portion of the stirring and fermentation tank 30 to biochemically decompose the secondary dried and fermented food waste W. In the case where it can be extinguished, when the food waste (W) is put into the pulverizing tank 20, a small amount of microorganisms and a processing base such as wood chips are simultaneously introduced, and sometimes the stirring body 63 is rotated through the rotary knob 64. By rotating the food waste (W) in the extinction process by rotating the), the food waste (W) is separately stored because the second drying and fermented food waste (W) in the storage tank 40 can be biochemically decomposed and extinguished. There is no need to dispose, and the storage tank 40 is periodically taken out of the case 10 and cleaned.

As described above, the present invention removes the water of the food waste (W) in the input tank 70, and then primary grinding and drying in the grinding tank 20, secondary drying and fermentation in the stirring and fermentation tank (30), food waste The volume and weight of (W) can be drastically reduced, and according to the present invention, it is possible to easily reduce or eliminate food waste at home or in a small restaurant unit, thereby greatly reducing the total amount of food waste. In each household unit, it is possible to feed, fertilize, incinerate, or dispose of food waste that is discarded in a small volume in a dry state more easily, which can contribute to resource recycling and environmental protection. You will get the effect.
