【発明の詳細な説明】
この発明は、動物性廃棄物からの蛋白質回収方
法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for recovering protein from animal waste.
従来、動物性廃棄物中に含まれた蛋白質源を利
用するためには、廃棄物を油温を利用して、加熱
油中にて脱水し、圧搾装置にて脱油して粉末状と
なつた廃棄物を飼料、肥料として使用することに
より、他の成分と一体の蛋白資源として利用する
ものであつたが、純粋な状態での蛋白資源として
回収するものではなく、高品質の蛋白質を含有し
た飼料、肥料として使用するにすぎなかつた。 Conventionally, in order to utilize the protein source contained in animal waste, the waste was dehydrated in heated oil using oil temperature, and the oil was removed using a pressing device to make it into powder. By using the waste as feed and fertilizer, it was used as a protein resource integrated with other ingredients, but it was not recovered as a protein resource in a pure state, but it was used as a protein resource containing high-quality protein. It was used only as feed and fertilizer.
この発明では、動物性廃棄物から純粋に蛋白質
を得るようにして、純粋な蛋白資源として広範囲
な利用ができる動物性廃棄物からの蛋白質回収方
法を提供せんとするものである。 The present invention aims to provide a method for recovering protein from animal waste that can be used in a wide range of ways as a pure protein resource by obtaining pure protein from animal waste.
この発明の実施例を詳説すれば、動物性廃棄物

羽毛その他動物の糞尿等を指称するものであり、
これらの廃棄物を予め或は中途より80℃〜150℃
に加熱した油中に浸漬し、減圧条件下すなわち、
初期減圧で10〜100mmmmＨｇの減圧をし、次いで
500〜750mmＨｇの減圧をして、脱水処理を行い、
その後油中より取出して連続圧搾機により圧搾す

た水溶性蛋白質を温湯中に溶解させる。 To explain in detail the embodiments of this invention, animal waste includes bones, internal organs, skin of animals, chickens, fish and shellfish, etc.
Refers to feathers and other animal excrement, etc.
These wastes are heated to 80℃~150℃ in advance or during the process.
immersed in oil heated to and under reduced pressure, i.e.
The initial pressure is reduced to 10 to 100mmmmHg, and then
Reduce the pressure to 500 to 750 mmHg and perform dehydration.
After that, it is extracted from the oil and deoiled by squeezing with a continuous press or deoiled with normal hexane to obtain a powdery solid as a dehydrated and deoiled product, which is heated at 60℃ to 70℃. The water-soluble protein contained in the dehydrated/oiled product is dissolved in the hot water by immersing it in warm water or by sprinkling it with warm water.
温湯中に溶解した水溶性蛋白質は、真空急凍乾
燥処理を行うことにより脱水して蛋白質のみが残

ことができる。 The water-soluble protein dissolved in hot water is dehydrated by rapid freeze-drying in a vacuum, leaving only the protein, and a pure high-grade protein in the form of powder can be obtained.
ここで真空急凍乾燥処理方法としては、水溶性
蛋白質を急激に凍結して凍結状態のままに真空乾

のを使用し、水溶性蛋白質をまず急激に凍結し、
次いで凍結状態で真空乾燥し、水溶性蛋白質表面
に出てきた水分の凍結が真空状態で氷化するのを
防止しながら脱水を行うものである。 Here, the vacuum rapid freeze-drying treatment method refers to a treatment method in which water-soluble proteins are rapidly frozen and then vacuum-dried in a frozen state. In this method, water-soluble proteins are first rapidly frozen using a system consisting of an airtight vacuum chamber, a heating machine, a freezing machine, a water condenser serving as an evaporator, and a vacuum pump.
The protein is then vacuum dried in a frozen state, and dehydration is carried out while preventing the water on the surface of the water-soluble protein from turning into ice in the vacuum state.
この発明によれば、動物性廃棄物を加熱油中に
て脱水し、脱油した後に、温湯にて水溶性蛋白質
を溶出させて、真空急凍乾燥にて脱水して蛋白質
をうるものであるため、純粋な蛋白質を得ること
ができる効果がある。 According to this invention, animal waste is dehydrated in heated oil to remove oil, water-soluble proteins are eluted in warm water, and proteins are obtained by dehydrating in vacuum rapid freeze-drying. Therefore, it is effective in obtaining pure protein.
