【Example】
An embodiment in which waste bone meat after dismantling of livestock such as cows and pigs is actually processed using the present apparatus will be described below. First, 100 kg of a fermentation treatment agent consisting of rice bran, other cereal slag, and the like is introduced from an introduction port 12 provided in the upper part of the treatment tank, and the oil in the hot water tank 3 is heated by the electric heater 4 so that the temperature in the treatment tank 2 becomes 70 ° C. Heated. Then, 20 kg of raw bone meat having a water content of about 30 to 40% to which meat, muscle, and the like had adhered were added.
[0013]
As the treating agent, rice bran and other cereal slag are mainly used, but a mixed treating agent obtained by mixing wood chips and the like can also be used. In the usual case, the amount of the treating agent is about 3 times the amount of the bone meat to be treated, but the amount of the treating agent is 3 to 5 times the amount of the moist, waste meat, waste internal organs, unnecessary residue, and the like. And larger amounts are more effective.
[0014]
After the introduction, the drive motor M was turned to rotate the stirring rod 6 forward and backward, and the mixing and stirring of the bone meat and the treatment agent were repeated. During this time, the oil was heated and adjusted with an electric heater so that the temperature in the processing tank increased by 5 ° C. per hour. One hour after the start of the operation, the temperature in the treatment tank reached 75 ° C., and the state of bone and meat therein was in a state in which bone, meat, and muscle had begun to separate. The processing operation was further continued, and after 2 hours, the temperature reached 80 ° C., and all bone meat and muscle were completely separated. Further, when 3 hours had elapsed after the introduction, the temperature reached 85 ° C., and the meat and the streaks were completely disappeared in the treatment agent, and only the bones were conspicuous. After 3 hours, the processing operation was stopped to wait for the temperature to decrease, and then the processed bone was removed. At the time of introduction, a large amount of meat and streaks, which were difficult to remove, adhered to the bones, but when taken out from the discharge door 13 provided below the U-shaped processing tank 2, only the bones became beautiful and glossy bones were obtained. Appeared. When only the bones were weighed, the weight at the time of introduction was 20 kg, but the weight was reduced to 16.8 kg. As a result, it was indicated that 3.2 kg of meat, muscle, moisture, and the like had adhered. Except for the bones, no meat, streaks, residues, etc. were found at all, and it is considered that they were completely decomposed.
[0015]
Two bones having a thickness of 1.3 cm, a width of 3 cm, and a length of 20 cm, which are considered to be elongated ribs, were prepared from the removed bones. First of all, I rolled an old newspaper into one of them and put it on it and lit the newspaper. Newspapers burned, and after a while the bones were lit. A small flame appeared along with the yellow smoke, and the flame disappeared in about 10 minutes while the entire surface was darkened while oil and fat were spread on the surface of the bone. Watch for about 3 minutes. This is not complete combustion but black and carbonized. I took out the charcoal, put it on the ground, and stepped on it lightly with my toes. It made a rustling sound and collapsed very easily. Another similar bone was prepared, the amount of newspaper was doubled, rolled up and fired in the same manner. The fire was very strong, and the fire was completely extinguished in about 12 minutes, wrapped in a seeing flame. Later, the white bone, which slightly retained its original shape, remained almost completely burned. It was found that complete combustion could be easily achieved by increasing the thermal power to some extent.
[0016]
【The invention's effect】
Waste meat after slaughtering and dismantling livestock such as cattle and pigs is difficult to burn and difficult to handle in the raw state. However, as in this treatment method, a fermentation accelerator is added to waste bone meat at a high temperature of 70 ° C or higher. By performing the heating and fermentation treatment, the fermentation treatment is performed in the treatment agent such as meat and muscle attached thereto, and the bone is carbonized, thereby facilitating incineration. In addition, the processing can be completed in about 3 hours.
[0017]
The temperature inside the treatment tank is raised by 5 ° C / hour, and warm air is sent at the same time as outside air for oxygen supplementation to promote fermentation. Can be processed. Further, since all odors in the processing tank pass through the deodorizing device and are exhausted to the outside, there is an effect that no pollution problem occurs.
