Calculation of kinematic parameters the centrifugation process

In this article, we will consider a centrifuge for separating fat from flakes for feed flour for animal husbandry. The raw materials necessary for the production of technical fat and dry feed are collected in all workshops and departments of the meat processing plant. Raw materials are divided into fat and fat-free. It can be soft and bony. The collection of raw materials can be combined with sorting. Heat treatment of raw materials is carried out by dry and wet (wet) methods. If the dry method is used, it is necessary to re-sort the collagen raw materials. This is due to the fact that under the influence of heat treatment, collagen hydrolysis occurs, which leads to the formation of a large amount of sticky broth.

With the dry method, disinfection and humidification are carried out in one device, and with the wet method – in a separate one.To obtain break-even raw materials during heat treatment, processing of raw materials in boilers at a temperature of 408 K takes up to 9 hours.During the heat treatment of raw materials, dry processing is more effective than wet.

The advantage of the dry method is that a small amount of water is used in the process, which is produced only in one apparatus and has a good yield of flakes and fat.

The disadvantage of the wet method is that most of the nutrients are converted into broth, which reduces the nutritional value of the pork. In addition, the steam consumption for evaporation of the broth increases, the release of fat decreases due to its circulation in the form of an emulsion. With increased acidity, second-grade fat is obtained (with the dry method – 80% of the first grade).
