Description

The waste food of vacuum drying and feed making apparatus

The present invention relates to a vacuum drying and food production apparatus of food waste for preparing food waste by vacuum drying at high temperature.

In general, garbage, which takes up a large portion of household waste, is food waste.

These food wastes have a high concentration of salinity, and fermentation to make compost has a problem of lowering the concentration of salinity in producing compost as the crops that are weak to salinity cannot be grown properly by the salts contained.

Therefore, to reduce the concentration of salinity in food wastes, a second environmental pollution was caused, and thus, to reduce the concentration of salinity, a lot of time and money were consumed, and thus the effect on productivity of compost was not obtained.

As a result, landfills were buried in landfills for low-cost disposal of food wastes, resulting in soil contamination by the large amount of leachate from landfills, resulting in significant environmental pollution. .

In this way, the environmental pollution caused by landfilling is high, and the method of incineration of food waste is used, but this also pollutes the air by other harmful substances such as dioxins generated during incineration. By polluting the soil rapidly and extensively, various agricultural products produced in the soil are contaminated, which is fatal to people and animals who consume the contaminated agricultural products. There was a problem such as being.

The present invention has a first purpose to manufacture and provide food waste by high pressure drying the food waste with high temperature steam, and to prevent the environmental pollution caused by food waste by making the food waste into livestock feed. will be.

Looking at the operation of the subject innovation is configured as follows.

When about 70% of food waste is introduced into the inlet 24 of the processing tank 2, the motor 26 is driven in a state in which the inlet 24 is closed and closed, thereby reducing the rotational force of the motor 26. The reduction shaft 27 decelerates to drive the rotating shaft 28.

Then, the food waste in the lower portion of the food waste introduced by the inner spiral pipe 29 and the outer spiral pipe 129 fixed to the rotary shaft 28 and the gap bar 229 and the heating tube 128 is raised to the upper portion. When the food waste is moved to the upper part, the food waste falls freely to the lower part and mixes the food waste repeatedly.

When the boiler 1 is operated, water is heated in the boiler 1, and steam is generated when the heated water rises to a constant temperature.

Then, the valves 11 and 12 are opened, respectively, and hot steam is introduced into the steam space 23 and the inner tank 21 to warm the inside of the processing tank 2, and the valves 13 and 14 are respectively opened. The hot steam introduced into the rotary shaft 28 by opening is introduced into the heating tube 128 fixedly formed at the outer circumference of the rotary shaft 28 to auxiliary food warming. The steam space 23 and the rotary shaft are thus heated. The moisture generated while the high temperature steam introduced into the 28 and the heating tube 128 cools is introduced into the boiler 1 through the first discharge tube 211 and the second discharge tube 114.

As the rotary shaft 28 and the inner and outer spiral pipes 29 and 129 rotate as the motor 26 rotates, the food waste is completely dried while vacuum drying, and the food waste at the bottom moves upwards. By repeating the vacuum drying is made smoothly.

When the steam introduced into the rotary shaft 28 and the heating tube 128 cools down in the vacuum drying process, the steam drops to the lower portion of the rotary shaft, and the fallen water is returned to the boiler through the second discharge tube 114.

The steam introduced into the steam space 23 through the first inlet pipe 111 heats the inside of the inner tank 21 from the outer wall of the inner tank 21, and the cooled steam (ie, the steam at a lower temperature) is It is sent to the boiler 1 through the 1st discharge pipe 211, and is heated again.

The gas containing the dust and water discharged through the first connecting pipe 33 is collected by the filter 31 installed in the dust collection tank 3, the high-temperature steam from which the dust is removed is a cooling tank ( The heat exchange is performed by the heat exchanger 42 while passing through the through hole 142 of 4) to cool the hot gas.

The refrigerant absorbed by the heat exchanger 42 in the heat exchanger is sent to the heat exchanger 47 to release heat, and the released refrigerant is sent to the heat exchanger 42 again to perform heat exchange.

At this time, while the hot gas is rapidly cooled, the moisture contained in the gas is cooled to fall to the lower portion of the cooling tank 4, and the fallen water is stored in the condensate tank 43.

Cooled and water-depleted gas is sent to the deodorizers 74 and 77 by the blower 76 or the vacuum pumps 72 and 73, and the deodorizers 74 and 77 deodorize the activated carbon and the platinum catalyst combustion. Will be released to the atmosphere in the removed state.

And the cleaning plate 30 is fixed to the rotating shaft 28 to rotate with the rotating shaft 28 to remove the food waste attached to the inner wall of the inner tank 21.

In this way, the food waste is vacuum-dried to produce livestock feed, and the water generated in the dust collection tank 3 and the cooling tank 4 is sent to a separate purification treatment device for purification and discharged as clean water. You can prevent it.

In this way it will be described the process of vacuum drying food waste.

When steam is heated for 2 to 3 hours through the heating tube 128 of the steam space 23 and the inner tank 21 and the rotating shaft 28, the structure of the food waste is destroyed.

At this time, the pressure of the gas generated in the process of destroying the tissue of the food waste may be operated by the blower 76 to discharge the gas in the treatment tank 2.

When the blower 76 is stopped while the food waste tissue is destroyed, and the valve 71 is opened and the vacuum pump 72 is operated, the pressure in the processing tank 2 is 2Kg / cm 2. At this time, the temperature in the treatment tank (2) is to vacuum dry food waste while maintaining the 70 ℃.

In this way, vacuum drying is performed for about 1 hour or more.

The vacuum pump 73 is also operated in a vacuum dried state to maintain residual pressure in the processing tank 2 for 4 to 5 hours while maintaining 1 TOrr.

As described above, when the food waste, which is dried by opening the outlet 25 in the dry state, is discharged from the processing tank 2, the food waste is conveyed by the first conveyer 51 and conveyed by the first conveyor 51. The foreign matter (iron, vinyl, paper, etc.) contained in the dried food waste is sent to the grinder 5 while automatically removing the manual work or a separate device from the foreign matter separating conveyor 52.

After crushing the thickened or thick food waste of the dried food waste sent to the crusher (5) to 30 mesh and transported to the storage tank (60) by the second transfer conveyor (53).

When a predetermined amount is stored in the storage tank 6, the feed for the livestock is completed by transferring to the packaging machine 7 using the third transfer conveyor 61 and packaging the package in an appropriate amount.

The effect of the present invention, which is constructed and acted in this way, is to dry the food waste to produce the feed of the livestock and produce the feed of the livestock, and to produce the food waste to the feed of the livestock, thereby preventing the environmental pollution by landfill or incineration. It is a very good design that can prevent and prevent environmental pollution by purifying the gas generated while feeding food waste.
