The invention discloses low-gelatinization-degree
staple food regenerated rice and a
processing technology thereof. The raw materials of the regenerated rice comprise main ingredients and auxiliary materials, wherein the main ingredients are one or more of
broken rice flour, potato
powder and
corn flour; the auxiliary materials are one or two of yam flour and
lotus root
powder. The
processing technology of the regenerated rice comprises the following steps: crushing the raw materials, adding water for
tempering, extruding and granulating, performing surface hardening treatment and
drying, wherein the step of extruding and granulating comprises the sub-steps: uniformly adding the materials subjected to water adding and
tempering into a
twin screw extruder, controlling the temperature of a compression section, a feeding section and a metering section of an extruder and a rotating speed of a screw rod, performing
extrusion melting on the materials, molding by virtue of a die head, and
cutting into the shape of rice grains by virtue of a cutter; the
drying step comprises the sub-step of
drying the materials in the shape of rice grains subjected to the surface hardening treatment into the
moisture content of 10-13 percent by adopting three-section gradient hot air. The regenerated rice is easy to form, and the processed
staple food regenerated rice is low in gelatinization degree, low in swelling degree, low in crack rate, low in
broken rice rate, uniform in rice grains, boiling-resistant and
steaming-resistant and good in taste.
