Meat and bone meal is a feed additive produced in the process of drying and grinding waste, which has valuable feed properties. Experts have established the fact that protein in the form of powder is absorbed by animals and livestock more efficiently than protein from vegetable feed.

Fodder meat and bone meal, used as an additive to other feeds poor in protein and vegetable fats, helps to accelerate the growth of animals, increase their total and muscle mass, and improve their general health. In addition, the flour obtained by grinding bones is used to enrich the soil of gardens, vegetable gardens and fields.

Typification of meat and bone meal production by varieties

Bone and meat-and-bone meal during processing has the appearance of a homogeneous dry powder with a specific smell, gray-white shade. If the appearance of the resulting product is always the same, its moisture content and protein content may vary.

Therefore, the volumes of produced meat and bone meal are divided by varieties:

• first grade;
• second grade;
• third grade.

It is no secret that bone meal is superior in quality to third grade flour and its price is higher.

Technological process of production of meat and bone meal.

The raw materials are:

• waste of meat processing enterprises;
• dead livestock that are unsuitable for food production;
• veterinary confiscations

Since the required percentage of components depends on the raw material used, it must be subject to strict control.

Features of the equipment for the production of meat and bone meal

Today, the market presents various equipment for bone meal, for example:

• bone grinder;
• hammer crusher;
• shutter for loading;
• screw conveyor;
• a pump that shakes water and fat;
• centrifuge for filtration;
• a pump that pumps out water and grease.

Note that these units are widely used as equipment for meat and bone meal.

Equipment for obtaining meat and bone meal:

• conveyor;
• receiving conveyor;
• gate for loading and unloading;
• drying units;
• conveyor stand;
• hopper for bone meal.

Equipment for the production of bone meal on the market

Bone meal is produced from animal bones, meat-and-bone - from bones from veterinary confiscation, carcasses and fragments of carcasses of dead livestock that cannot be used for food, as well as from inedible waste from meat processing and meat processing industries. Raw materials for the production of bone meal must be checked for quality and safety by veterinary authorities and veterinary supervision.

Such flour contains fiber, minerals, proteins, is a source of protein and is used as an additive in the production of compound feed for agriculture, feed for dogs, cats and other domestic animals, as well as poultry and livestock.

In addition, bone and meat-bone meal as a valuable source of phosphorus is used in the production of fertilizers for street and potted plants. Another way of using flour from animal bones is to use it as environmentally friendly fuel at industrial enterprises.

The main consumers of these products are agricultural enterprises, farms, manufacturers of compound feed and feed for pets, livestock, poultry, agricultural enterprises and private individuals, fertilizer manufacturers, as well as zoos, nature reserves and large industrial enterprises that use alternative fuels.

The main equipment for the production of bone meal

Enterprises working in this field are offered both individual units for use in certain areas of the technological process and complex production lines for production equipment.

The minimum equipment of the production line consists of the following units:

1. shredder of bone and meat and bone raw materials;
2. the container in which crushed raw materials are received;
3. conveyor of crushed raw materials;
4. installations for cooking raw materials;
5. chopper of cooked raw materials;
6. a centrifuge in which filtration, settling of the cooked mixture and its separation into meat and bone mince and fat are carried out;
7. pump for pumping out water;
8. drying complex for complete removal of moisture from raw materials;
9. raw material transfer conveyor further down the line;
10. crusher for final grinding of flour;
11. receiver of finished products;
12. the device for packing and packaging of finished products.

In addition to the specified devices and units, the enterprise must organize the storage of raw materials and finished products - for this, it is necessary to have premises equipped with refrigeration equipment.
