Tunnel forming machine
Technical field
The present invention relates to a kind of food processing machinery, especially a kind of system staple food former.
Background technology
Present domestic staple food steamed bun former is divided into double helix extrusion modling and the round as a ball moulding two big classes of conveyer belt, and the manufacturing firm of this two kind equipment is more, mainly concentrates on China the north, is representative with Shaanxi, Shandong, Hebei, Henan especially.But there is very big defective in this two series products, the one-shot forming rate of the steamed bun making machine of double helix extrusion modling is low, have only about 40%, and to finish all face blank moldings substantially through three times to four times ability with a collection of, suppress the steamed bread quality that different passes mold very large difference is arranged, and it is very big to the destruction of dough to adopt the double helix extruding to carry, and gluten is torn cut-out, directly influences the quality of steamed bun, operate also more loaded down with trivial details, and,, must manually it be put down in order to guarantee the external form of steamed bun because the steamed bun base that squeezes out has an end spiral, automaticity is too low, and the kind of producing is single, can only produce a kind of round steamed bun, and the round as a ball moulding of conveyer belt, because the steamed bun external form of moulding is rule not too, rough surface, productive rate is low, is slowly eliminated by market.
