include the destruction of foreign materials structure: its outer cover and shells to
give a non-uniform rough grinding the mixture.
The next group of tasks associated with the destruction of the inner structure of
materials: his skeletal structures, fiber, plant cell membranes, connective tissues and
animal products, etc.
External, internal structure destroyed by mechanical processes of cutting,
crushing, grinding, combined with thermal, hydraulic, chemical, biochemical
processing of raw materials.
Tasks for recovering useful substances from the feedstock related to the division
of nutrients and internal impurities. These contaminants include constituents of raw
materials that contain mineral substances of a formulation of the finished product: the
outer shell, the skeletal structure of cellulose, water and others.
On separation comes heterogeneous mixture of solid and liquid feed
components: dry substances, emulsions, suspensions, complex heterogeneous
structure.
Components of these compounds have different physical-mechanical properties
which are caused by phase state, the geometrical dimensions, density, surface
roughness, melting and boiling points, and other electromagnetic characteristics.
Because of these differences there is a possibility to divide the heterogeneous
substances in the liquid and solid, gaseous and liquid (or solid), heavy and light, large
and small, long and short, easy - and refractory, magnetic and non-magnetic
materials, etc.
A characteristic feature of the equipment in the complex C - this is what
transforms the feedstock structure as a result of its operation. Including intermediate
obtained semi-technological properties which allow efficient recovery of raw mineral
substances, removal of impurities.
When removing nutrients, removal of impurities can be widely used mass
transfer processes associated with convection, diffusion, precipitation, filtration,
extraction, distillation, and others.
Processes can be intensified by pressing, vacuuming, centrifuging, vibration,
heating, cooling and other effects on the processed products.
If not have different physical properties in vivo components of the mixture,
these differences are created artificially by additional exposure to the mixture.
For example, when cleaning organic acid raw juice of sugar beet removed using
lime mortar, and carbon dioxide.
In process lines for the production of finished goods assembly method is usually
processed secondary raw materials, ie, components of agriculture products resulting
from the operation of lines for primary processing of raw materials.
In the secondary raw material internal and external impurities of natural raw
