Embodiment 1

[0027] (1) Raw bone selection and pretreatment

[0028] Saw the raw bones of healthy and disease-free animals into short bones with a length not greater than 20cm, and set them aside;

[0029] (2) Surface embrittlement, dry bone cleaning and coarse crushing

[0030] Place the short bone obtained in step (1) in a rotary hot air furnace with a hole diameter of 15mm on the bottom plate of the object, spread the aggregate in a single layer, and pass in dry hot air at 160°C until the remaining non-bone tissue on the surface of the raw bone, If the skin, hair, minced meat, and periosteum are thermally denatured and brittle, then they are taken out and placed in an operating environment with a relative humidity of 25%, and hydrogen peroxide with a mass concentration of 30% is added to the surface of the aggregate according to the bone mass percentage of 0.5% to make it last. Embrittlement, followed by rolling, kneading, and rubbing to realize dry bone cleaning, remove the embrittled...

Embodiment 2

[0036] Obtained by the following steps:

[0037] (1) Raw bone selection and pretreatment

[0038] Saw the raw bones of healthy and disease-free animals into short bones with a length not greater than 20cm, and set them aside;

[0039] (2) Surface embrittlement, dry bone cleaning and coarse crushing

[0040] Place the short bone obtained in step (1) in a rotary hot air furnace with a hole diameter of 15mm on the bottom plate of the object, spread the aggregate in a single layer, and pass in dry hot air at 175°C until the remaining non-bone tissue on the surface of the raw bone, If the skin, hair, minced meat, and periosteum are thermally denatured and brittle, they are then taken out and placed in an operating environment with a relative humidity of 28%, and hydrogen peroxide with a mass concentration of 30% is added to the surface of the aggregate according to the bone mass percentage of 1.25% to make it last. Embrittlement, followed by rolling, kneading and rubbing to achie...

Embodiment 3

[0046] Obtained by the following steps:

[0047] (1) Raw bone selection and pretreatment

[0048] Saw the raw bones of healthy and disease-free animals into short bones with a length not greater than 20cm, and set them aside;

[0049] (2) Surface embrittlement, dry bone cleaning and coarse crushing

[0050] Place the short bone obtained in step (1) in a rotary hot air furnace with a hole diameter of 15mm on the bottom plate of the object, spread the aggregate in a single layer, and pass in dry hot air at 190°C until the remaining non-bone tissue on the surface of the raw bone, If the skin, hair, minced meat, and periosteum are thermally denatured and brittle, they are then taken out and placed in an operating environment with a relative humidity of 30%, and hydrogen peroxide with a mass concentration of 30% is added to the surface of the aggregate according to the bone mass percentage of 2.0% to make it last.

Abstract

The invention belongs to technologies of animal product and by-product processing, and relates to a high-quality bone grain and a production method thereof. The high-quality bone grain is characterized by being prepared in a manner that raw bones of an animal are taken as raw materials and subjected to selecting, preprocessing, surface embrittlement, dry process bone cleaning, coarse crushing, microwave and far infrared combined type continuous sterilization carbonization and ashing, particle size adjustment, high-pressure supercritical fluid degreasing, etc. The high-quality bone grain contains active ossein, and the content of fat is below 2%, so that the high-quality bone grain is a quality raw material for producing bone meal and bone gelatin. In a product production process, full utilization of the raw materials is realized; no pollution, waste residues, waste steam or hazardous materials are produced; water and time are saved; no strong acid or strong base is utilized; and the product safety is high.

Description

technical field [0001] The invention belongs to the field of animal product by-product processing, in particular to a production method of high-quality bone grains. Background technique [0002] my country is a big country for raising livestock and poultry. The total national meat output exceeds 50 million tons, accounting for about 1 / 4 of the world's total meat production. The livestock and poultry bones produced exceed more than 15 million tons, and bone resources are extremely rich. Relevant research results show that bone has high nutritional value and is rich in protein, fat, minerals and other nutrients, and is a valuable nutritional resource. But at present, about 10 million tons of livestock and poultry bones are not effectively utilized every year, resulting in a great waste of resources and environmental pollution. Animal bone tissue is composed of osteocytes (about 2% to 3% of the total volume) and calcified bone matrix. About 65% of the bone matrix is ​​mineral...
