Description
The present invention relates to the processing method of waste material of animality.
Up to now, about waste material of animality, i.e. the bone of animal, chicken, aquatic products, internal organ, skin, feather, the fecaluria of other animal etc.The stench that has the very strong generation because of basic nitrogen to cause produces Odour nuisance when handling owing to it, thereby does not also consider to handle the construction of field at present.
Thereby, the applicant discloses a kind of method for addressing the above problem to open in the clear 58-186486 communique the spy earlier, this method is with waste material of animality, be placed in animal oil, fish oil, the plant wet goods oil plant, under reduced pressure,,, basic nitrogen decomposes the method for eliminating stench thereby being carried out substance by the heating of oil.
In addition, the applicant opens in the flat 6-277651 communique the spy and also discloses a kind of processing method, this method is to add animal oil, fish oil, plant wet goods oils in the closed container that is known as the storehouse card, heating then, and then to wherein dropping into the garbage that is packaged in the polybag, carry out triphasic decompression on one side, Yi Bian carry out processed, the garbage with polybag and dehydration separates then.
Yet, though opening the processing method of clear 58-186486 communique, above-mentioned spy can carry out the deodorization of waste material of animality, processed is also insufficient.In addition, the spy opens in the dressing method of flat 6--277651 communique, also can't be positively with the waste material of animality processed, owing to processed not exclusively cause along with the time through producing stench again, have environmental problem being provided with of treatment facility.
Thereby the object of the present invention is to provide a kind of processing method of the waste material of animality that can address the above problem by positively waste material of animality being dewatered.
The present invention relates to a kind of processing method of waste material of animality, it is characterized in that, in closed container, make heated animal oil by stirring on one side, fish oil or vegetable oil contact with waste material of animality, keep on one side temperature in the closed container in the early stage in the decompression process at 110 ℃ state, under this state the closed container internal pressure had been decompressed to 500mmHg in about 40 minutes, make the waste material of animality solidification-stableization, in the decompression process closed container internal pressure was decompressed to 20mmHg from 500mmHg in mid-term in about 40 minutes then, simultaneously temperature in the closed container is reduced to 70 ℃ rapidly, be warming up to 120 ℃ afterwards, in the later stage decompression process, the closed container internal pressure maintained at last 20mmHg and temperature maintenance 120 ℃ about 40 minutes, dewater.
Below, specify the present invention according to embodiment.
(1) at first, be 65m at sealable internal volume
3Saucepan in, single oil or miscella such as the animal oil about 800kg of packing into, vegetable oil, fish oil, chicken fat, the steam that is pressed into by the cannula portion at saucepan heats oil, and temperature in the saucepan is heated to about about 110 ℃.
(2) adding in the deep fat in above-mentioned saucepan,, about 4 tons of the internal organ of input ox, skin etc. are closed saucepan.
(3) as the preliminary vacuum process, on one side temperature in the saucepan is remained on 110 ℃, make the vavuum pump action on one side, in about 40 minutes,, reduce to 500mmHg from normal pressure (760mmHg) gradually with the saucepan internal pressure.At this moment, can in saucepan, stir as required.By this temperature in the saucepan is remained on preliminary vacuum under 110 ℃, can impel water evaporates in the waste material of animality to reach the purpose of dehydration.
(4) in the mid-term decompression process, gradually from 110 ℃ be reduced to 70 ℃ with temperature in the saucepan first half, and gradually from 70 ℃ rise to 120 ℃ with temperature in the saucepan latter half.On the other hand, in about 40 minutes, reduce to 20mmHg from 500mmHg gradually.
(5) in final decompression process, when temperature remains on 120 ℃ in the saucepan, carry out the saucepan internal pressure is remained on the reduced pressure treatment of 20mmHg.This state was kept about about 40 minutes.
As mentioned above, by three sections reduced pressure treatment, at first be in the early stage in the decompression process, water soluble protein in the waste material of animality, the nutrient that animal glue etc. are useful, solidification-stableization in the tissue of this waste material of animality, thus prevent the outflow and the decomposition of these compositions; The processed of moisture is thoroughly finished this processed in the later stage decompression process in promptly organizing in the decompression process mid-term.
Just, in the present invention, not to make the decompression of saucepan internal pressure sharp, but in the early stage in the decompression process and mid-term decompression process slowly reduce pressure, on the other hand, be to make temperature reduction in the saucepan mid-term in the decompression process, therefore can make protein and inner thermocoagulation really in the waste material of animality, thereby prevent and oily emulsification ratio, can't hinder the displacement of the proportion of the moisture that in final decompression operation, reduces pressure significantly and cause and oil, so that oil is soaked in fully in the tissue, can basic nitrogen be fully worked, the thermal denaturation of utilizing oil to cause makes the basic nitrogen chemical breakdown, thereby can eliminate fully.
And, the vegetable oil that heated, fish oil or animal oil, the moisture content displacement with containing in the above-mentioned waste material of animality makes contained humidity be exuded to the extracellular of tissue fully, thereby can carry out processed soon.
Then, from saucepan, take out the waste material of animality of crossing through above-mentioned decompression heat treated, it is used pressing device, carry out mechanical expression as screw extruder etc., or use the centrifugal separator centrifugation, the oil content that contains in the waste material of animality is separated remove, as required, with de-oiling agent de-oiling such as n-hexane so that its oil content is reduced to below 8% then it is pulverized, thereby obtain to remove fully the feedstuff of stench.
In addition, also can be in de-oiling under the reduced pressure, the material that will take off oil drags for up with reticulate body, as it is, in being in the saucepan of decompression state, with squeezings such as centrifugal separators.Like this and since be recovering state with sticking attaching oil to normal pressure, thereby can prevent that oil is impregnated into the inside of goods.
And, though be to carry out heat treated by oily temperature can make aminoacid protein of containing etc. be solidified processing, if but drop in the hot water once more, excellent dissolution at an easy rate in hot water then, and, because hygroscopicity is not high, thereby can moisture absorption in preserving, powdered substance can be not fixed, thereby can make its taste in statu quo reproduce the amino acid of liver, internal organ, the taste that sodium glutamate etc. are intrinsic, and the nutrient that contains in the raw material in statu quo kept so that nutritious and tool is delicious, can in " spread and use seasoning matter " flavorings such as (ふ リ カ サ), utilize.
With the material that the processing method of waste material of animality of the present invention is made, not only can be used as full material and spread with flavorings such as seasoning matter and use, also can in other many purposes, use, for example also can be used as fertilizer and extender and use.
Among the present invention, not to make the decompression of saucepan internal pressure sharp, but reduce pressure lentamente through preliminary vacuum process decompression process in mid-term, on the other hand, in the mid-term decompression process, make temperature reduction in the saucepan, thereby can make the protein in the waste material of animality spread all over inner thermocoagulation really, thereby prevent and oily emulsification ratio, can't hinder the displacement of the proportion of the moisture that in final decompression operation, reduces pressure significantly and cause and oil, so that oil is soaked in the tissue fully, can fully work to basic nitrogen, the thermal denaturation of utilizing oil to cause makes the basic nitrogen chemical breakdown, thereby can handle waste material of animality with the state of roughly eliminating fully, and handled thing can be used for feedstuff, flavoring, fertilizer, multiple uses such as extender.
