JPS6140752A - Production of feed, etc., from blood, etc., of animal, or fish and shellfish - Google Patents

Abstract

PURPOSE:To produce a feed having high nutritive value, good digestibility, improved color tone, preservable for a long period, in a short time at a low manufacturing cost, by coagulating blood thermally, pressing and dehydrating it, and dehydrating it by the use of a heating oil as a heating medium. CONSTITUTION:Blood of animal, or fish shellfish is heated at 70-110 deg.C at normal pressure, and coagulated. It is mechanically pressed, and dehydrated into about 50wt% water content, to give coagulated blood. Then, the coagulate blood is dehydrated by the use of a heating oil as a heating medium under reduced pressure, an oily component is completely removed from the prepared dehydrated product, and optionally ground.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a method for producing feed, medicines, food additives, etc. from the blood of animals, fish, and shellfish.

(b) Conventional technology Conventionally, the blood, bones, and internal organs of animals, fish, and shellfish contain a large amount of high-quality protein, vitamins, hormones, calcium, etc., so they are dehydrated to produce powdered feed, etc. As a method for producing such feed, etc., a method has been used in which blood, etc. is vacuum-heated and dried. Further, when drying, a method of immersing the raw material in heated oil and dehydrating it using the heated oil as a heat medium can also be considered.

(c) Problems to be solved by the invention Therefore, the conventional method has high fuel consumption, high cost of the final product,
In addition, drying efficiency deteriorates and drying time becomes longer, resulting in thermal decomposition or thermal deterioration of proteins, vitamins, hormones, etc. contained in the raw materials, making it difficult to obtain high-quality feed.

Furthermore, when raw materials are dehydrated using heated oil as a heat medium, it is possible to reduce fuel consumption, but blood is eluted into the heated oil and the heated oil becomes colored, and this heated oil may cause damage to other products. The dehydration process was difficult and the bullets could not be collected properly. In addition, the blood pigments faded, causing the final product to have a poor color and lowering its commercial value.

(d) Means for solving the problem In the present invention, heated oil preheated to a constant temperature is stored in a cupper, and 111
By dehydrating coagulated blood soaked in water using heated oil as a heat medium, and then deoiling the dehydrated product to produce feed, etc., processing can be done in a short time, and the production cost is low.
We also aim to produce high-quality feed that can be stored for a long time, has high nutritional value, good digestibility, good color, and high product value, and provides a method for producing feed from the blood of hanging animals, fish, and shellfish. It is something.

(e) Effect In the present invention, blood is thermally coagulated and then dehydrated by compression, and then dehydrated using heated oil as a heat medium. Therefore, the blood does not dissolve in the heated oil, and the efficiency is lower than 8. In addition to being able to recover the water, malodor components are also removed by dehydration in advance, and the burden of dehydration during dehydration due to oil temperature is reduced, resulting in low costs.

In addition, since the heated oil is not stained with blood, the heated oil after treatment can be reused for dehydrating the product, making it possible to carry out profitable treatment.

Moreover, in this dehydration treatment, blood solidified substances penetrate into the tissue and are heated from inside and outside the tissue through heating.
Rapid and efficient dehydration takes place in a short time, and nutrients such as proteins, vitamins, and hormones contained in blood are broken down.
It can be recovered without deterioration.

In addition, malodorous components such as blood, oil, etc. are decomposed or transferred to heated oil and removed, and the final product contains only a small amount of water, making it possible to produce feed etc. that can be stored for a long time without fear of spoilage.

Early pressing also improves digestibility.

(f) Effects Since the present invention is configured as described above, it is possible to perform efficient dehydration treatment in a short time, low manufacturing cost, long-term storage, high nutritional value, good color tone, and low g depth. Moreover, it is possible to produce high-quality feed, etc., which is highly digestible and has a high lii value.

(g) Example The detailed description of the embodiments of the present invention is as follows.

First, the blood of animals, fish, and shellfish is poured into a steamed toad, heated under normal pressure at a temperature of 70 to 110°C for 10 to 60 minutes to coagulate the blood, and only the solid matter is removed from the steamed toad and squeezed.
The blood is dehydrated to a water content of approximately 50% by mechanical treatment to obtain coagulated blood.

The coagulated blood is put into a container along with the bones and internal organs of animals, fish, and shellfish, and heated oil preheated to 80 to 120 degrees Celsius is stored in the container. J3<.

Next, open the lid of the pump, reduce the pressure inside the pump, and lower the oil temperature to 8.
This device stirs the inside of the cutter while maintaining the temperature between 0 and 120°C, and the coagulating surface liquid and bones immersed in the heated oil,
The internal organs are mixed with each other in oil and rapidly heated to 1I in 30 to 60 minutes in a reduced pressure atmosphere and heated oil as a heating medium.
It is configured to be watered at t2.

Next, the dehydrated product is extracted from the oil, the oil content is removed by squeezing or centrifugation, and if necessary, the oil content is completely removed using a deoiling agent such as normal hexane, and if necessary, the oil content is pulverized. do.

Incidentally, the blood to be put into the steaming pot may be adjusted in pI-1 with hydrochloric acid, acetic acid, etc. in advance.

The embodiment of the present invention is constructed as described above, and coagulated blood that has been thermally coagulated and dehydrated in a steaming pot is
Even if immersed in heated oil, it will not dissolve or dissolve in heated oil.
It can be dehydrated and recovered either alone or mixed with bones and internal organs.

Moreover, since such dehydration treatment is carried out using heated oil as a heat medium, the heated oil penetrates into the coagulated blood, bones, and internal organs tissues and replaces water, causing the heated oil to coagulate from inside and outside the tissue. Because it is heated through the water, rapid and efficient dehydration is performed in a short time, and the large amount of proteins, vitamins, hormones, etc. contained in coagulated blood, bones, and internal organs can be recovered without being degraded or altered. It is something that

By dehydrating in advance before immersing in oil and dehydrating in heated oil, malodorous components contained in coagulated blood, etc. are decomposed, transferred to heated oil, or removed together with water. It is something. In addition, the initial pressing improves digestibility.

Therefore, the final treated product contains a large amount of protein, vitamins, and hormones, has no bad odor, does not spoil due to moisture, and can be stored for a long time, and can be used, for example, as feed, medicine, or food additives.
