Further, in step s 302, the purple potato composite rice of almond parameter best in quality is determined in the following way:
almond purple potato composite rice feed moisture is on the impact of grain of rice gelatinization degree and puffed degree
5 district's processing temperatures 80,90,110,130 are fixed to comminutor, 165 DEG C.Screw speed is 180r/min, and charging rate is 30r/min, and die diameter is 6mm.Do material moisture and single factor experiment is affected on product puffed degree and gelatinization degree, totally 5 process.
Experimental data:
Table 1 material moisture single factor experiment parameter
Experimental result:
As can be seen from Fig. 1 and Fig. 2, along with the raising of moisture content of material, the puffed degree of product and gelatinization degree all present the trend of falling after rising, and when water content is 16%, the puffed degree of product is up to 4.0, and when water content is 18%, gelatinization degree is up to 88%.The expanded principle of cereal mixed powder be moisture in mixed powder at extrusion chamber through high temperature high pressure process, the moisture Quick-gasifying extruded, forms uniform air cavity, makes cereal mixed powder present expanded state.During water content height, starch and protein water suction increase, protein denaturation, and the stickiness of material increases, and between material and extrusion spiral component, frictional force increases, and in machine barrel, the time of staying is long, and machine external and internal pressure difference is increased, and puffed degree and gelatinization degree raise; When the water content of material continues to increase, the moisture in material act as the effect of lubricant.Material suffered shearing, rubbing action in machine barrel weaken, drag reduction, and the time of staying is short, and die orifice pressure is reduced; Because moisture absorbs a large amount of gasification latent heats in the gasification of die orifice place, machine barrel and die orifice place temperature are reduced, is difficult to be formed high-temperature high-pressure state, thus the puffed degree of product and gelatinization degree are all reduced.
extrusion temperature is on the impact of the purple potato composite rice gelatinization degree of almond and puffed degree
experimental technique
Standing screw rotating speed is 180r/min, and charging rate is 30r/min, and die diameter is 6mm, and material moisture is 16%.Do extrusion chamber temperature and single factor experiment is affected on product puffed degree and gelatinization degree, totally 5 process.
experimental data:
Table 2 extrusion temperature arrange θ/DEG C
experimental result:
As can be seen from Fig. 3 and Fig. 4, processing temperature has products radial puffed degree extremely significantly to be affected.Each group of process all reaches the pole level of signifiance to the impact of products radial puffed degree.3rd group of radial puffed degree is the highest, is 3.7; Afterwards, along with processing temperature raises, products radial puffed degree is on a declining curve.This is because processing temperature rises, starch crystal melt, material viscosity declines, simultaneously more weak in branched amylopectin molecules hydrogen bond rupture speed is accelerated, and a serobila dissociates, and becomes linear molecule, and it is directed vertically, therefore mobility strengthens, and in die head, flow resistance declines, the pressure drop when the Vth district; On the other hand, because material viscosity declines, more weak to the constraint ability of gas, so that break earlier in Bubble Formation Process, thus radial puffed degree declines.When processing temperature is lower, product quality is comparatively hard, and color and luster is dark yellow, and porosity is not of uniform size.Along with processing temperature raises, it is crisp that product becomes quality, golden yellow color, porosity uniformity.So when adopting this equipment to process dilated food, processing temperature is comparatively suitable with the 3rd group.
In material, the gelatinization of starch carries out under the condition of suitable temperature absorption enough moisture and heat.In extrusion process, the radial puffed degree that material absorbs is in the trend of falling after rising.When screw speed is lower, heat has 2 sources: the heat that 1. material is sheared in machine barrel, rubbing action produces; 2. by the heat of barrel wall conduction acquisition.The latter expect that suffered shearing force also increases thereupon, it is larger that the amylose that part is large becomes role.When barrel zone temperature is lower, the heat that material absorbs is few, and the gelatinization rate of extrudate is lower.Along with barrel zone temperature constantly increases, the gelatinization degree of extrudate also constantly increases, and when barrel zone temperature is set to the 3rd group, gelatinization degree reaches maximum (82%).But barrel zone temperature is too high, the sugar of the protein in raw material and starch degradation may be caused at high temperature Maillard reaction to occur, and the too high partial starch that will cause of barrel zone temperature is coked, thus causes the decline of gelatinization degree.Also may be temperature too high time, in material, moisture premature evaporation is fallen, and in material, moisture is too low, starch heat, and melt mixed is uneven, and temperature difference of temperature field is large, even occur not when low moisture not easily gelatinization cause.So when adopting this equipment to process dilated food, processing temperature is set to the 3rd group for comparatively suitable.
screw speed is on the impact of almond purple potato composite rice gelatinization degree
Fixing charging rate is 30r/min, and material moisture is 16%.Extrusion chamber temperature is set to the 3rd group, and die diameter is 6mm, and doing extrusion chamber temperature affects single factor experiment to product puffed degree and gelatinization degree, totally 5 process.
Experimental data:
Table 3 screw speed experiment of single factor parameter
Experimental result:
As can be seen from Fig. 5 and Fig. 6, along with the increase of screw speed, radial puffed degree is in the trend of falling after rising.When screw speed is lower, the shear action that material bears is little, and along with the increase of screw speed, the shearing force suffered by material also increases thereupon, the amylose that part is large becomes Small molecular, the partial side-chain Small molecular of amylopectin is also dissociated out, and the hydrogen bond action between starch molecule is weakened, and the free space of molecular skeleton strengthens, moisture in material is more easily evenly infiltrated, and it is swelling to make it occur, produce more loose tissue, thus product puffed degree increases; When screw speed is 180 r/min, the radial puffed degree of product is up to 4.2; When screw speed continues to increase, the time of staying of material in machine barrel reduces greatly, when material has little time to absorb enough from barrel wall, in material, moisture premature evaporation is fallen, and in material, moisture is too low, starch heat, melt mixed is uneven, temperature difference of temperature field is large, even occurs the particulate inclusion of ungelatinized in the product, and thus product expansion rate reduces.The screw speed of extruder determines the time of staying of material in machine chamber and pressure.It is appreciated that screw speed just must can have good gelatinization effect, when screw speed is lower with charging rate reasonable combination, the time that material stops in Builking cavity is longer, gelatinization is abundant, and when screw speed is 180r/min, the Hu Huadu of product is up to 85%.Along with the raising of screw speed, the time of staying in the Builking cavity of material reduces, but is increasing because material is subject to shear action, and absorb mechanical energy higher, therefore gelatinization degree and dilation decline not remarkable.When improving screw speed further, material has little time timely reaction and is just extruded Builking cavity in Builking cavity, therefore gelatinization weak effect.
the impact of the purple potato composite rice puffed degree of charging rate team almond and gelatinization degree
Standing screw rotating speed is 180r/min, and material moisture is 16%, and extrusion chamber temperature is T 3, die diameter is 6mm, and doing screw speed affects experiment of single factor to product puffed degree and gelatinization degree, totally 5 process.
Experimental data:
Table 4 charging rate single factor experiment parameter
Experimental result:
As can be seen from Fig. 6 and Fig. 7, the products radial puffed degree impact of charging rate team is little, and different charging rates has impact to a certain degree to gelatinization degree, when charging rate is 30r/min, the gelatinization degree of product is the highest, is 78%, along with the growth of charging rate, the gelatinization degree of product reduces.This may be the interaction influence by charging rate, when screw speed is fast, when charging rate is slow, cereal mixed powder is overstand in machine chamber, or screw speed relative feed rates slower time, the gelatinization degree of product is all undesirable, only has screw speed and charging rate to complement each other, and guesses and likely reaches good extrusion effect.
