Criterion biological value - the amino acid composition. Their content in
the extruded rods using the method of ion exchange chromatography essentially
exceeds raw materials due to protein concentration Rx additives at different
ratio.
The method of ion exchange thin layer chromatography showed qualitative
and quantitative carbohydrate composition of the extrudates, it is efficiently
balanced.
Extruded products are highly "energy, food and biological value, have good
consumer properties, balanced composition and can be recommended in
everyday nutrition, especially for children of school age.
To simulate the proposed technical solutions is shown developed on the
basis of structural-parametric synthesis of computer-aided design (CAD) is the
most important extruder element - screw working body, which allows to
calculate the optimal technological and design parameters of the equipment
subject to the quality of the product and minimize the specific energy
consumption in compliance with the strength characteristics of the material
screw.
Optimization of the extruder is held at maximum efficiency;/, as this
parameter is "convolution" the greatest number of the selected set of effect
parameters, which act as constraints optimal area.
The "Shnek_ CAD" is implemented as a master of construction of optimal
areas of the screw parameter design and analysis designed for basic strength
characteristics. housing the screw and cavity providing intensification of the
process, the stabilization processing biosyrya various modes and, ultimately
obtain ready to eat foods high - promising solutions extruders structural elements
have been proposed.
Thus, a twin-screw extruder (Pat. Russian № 2,172,246) to stabilize the
pressure and temperature of the product before the matrix area by establishing
flow from it through the cylindrical extrudate melt channel in previous
technological extruder zone. The design of the forming extruder device (US Pat.
RF. The V » 2185286} provides the product of pressure stabilization before the
matrix zone when changing tehnological process parameters due to the"
automatic "variation proShdntz section forming channels. Range of flow cross
section forming the channel are determined by extruder output, the geometrical
dimensions of the matrix and rheological properties of raw materials.
The high torque of the rotating extruder sleeve (Pat. RF number 2205105)
and combined with the rotating screw enables processing of high-viscosity
multicomponent mixtures. The sleeve and the screw have a complex
configuration, providing optimum temperature, it can effectively and efficiently
carry out the extrusion process of thermoplastic materials.
The technological line with a rational layout of equipment, methods of
producing functional products and automatic control of the extruder operation.
