Raw material is corn starch, together with the glutinous rice flour and potato powder.
The Techniques Process of expanded food: mixing of raw materials—conditioning—feeding—squeeze—forming—cutting —drying —packing —flavoring products.
Improvement opportunities: adjust the production equipment, materials and formulations; improve product stability and customer satisfaction.
Table 1 shows that the mixing of raw materials, conditioning, feeding and squeeze are the main process of the expansion ratio.

Usually earth rockfill materials of cofferdam will be changed as its particle breakage and position transformation during cofferdam construction and working processing on account of materials sedimentation or external load fluctuation such as water pressure change induced by upstream water level change, of course the material parameters of which will change great.
Based on strength reduction method, considering change of intensive parameter of earth rockfill materials during cofferdam construction, the slope stability safety coefficient calculation model can be expressed as : （2） In which denotes earth rockfill materials confining pressure which changes with alteration of filling process, represents internal friction angle of earth rockfill materials on the condition that equals atmospheric pressure, designates the magnitude of reduction of as increment of , c is cohesion of materials.

The micro-hardness tests are used in order to evaluate the changes of the materials hardness at the microscopic scale and are widely used to investigate material properties.
The Vickers micro-hardness for most materials is greater than the macro-hardness and depends on the applied load and test conditions [6, 7].

Besides, to process different materials of balls, it should use different processing parameters.
In addition, the motion state of different materials balls will be different under the same processing conditions.

Values of emissivity coefficients the tested materials To improve the efficiency of measurement was used sanding operation of batch sheets.
For the tested materials after heating the emissivity increases nearly doubled relatively to the material before heating. 3.
Coefficient of emissivity depends on the method of surface preparation and does not depend on the species of the tested materials. 4.
