Abstract
The utility model provides a variable-pitch extrusion screw rod. A thread on the extrusion screw rod is divided into a big lead extrusion curing section and a small lead extrusion curing section, wherein the pitch of the big lead extrusion curing section is greater than that of the small lead extrusion curing section. According to the utility model, by improving an equal-pitch screw rod, the front-section pitch is greater than the rear-section pitch in the same screw rod, and rice noodles slurry forms a relatively high compression ratio in a closed curing barrel so that rice noodles are tight and the curing and puffing degree is high.
Description
Technical field
The utility model relates to the ground rice field of mechanical technique, refers in particular to a kind of displacement extruding screw for rice-flour noodles machine.
Background technology
Ground rice refers to take rice as raw material, strip, the thread rice made products made through operations such as immersion, boiling, press strips, rather than the granular material made from grinding take rice as raw material of understanding on the meaning of a word.The ground rice quality is pliable and tough, high resilience, and poach is not stuck with paste soup, and dried stir-fry is not easily broken, is equipped with the code or soup stock carries out that soup boils or do and fry of respectively planting vegetables, and is smooth tasty, deeply is subjected to liking of the especially southern consumer of consumers in general.The ground rice kind is numerous, can be divided into row's ground rice, square ground rice, ripple ground rice, dried thin rice stick, wet rice flour noodles, dry rice flour etc.
The feeding of existing self heating shape rice-flour noodles machine and extruding screw are two independently screw rods, last play carry and and milling effect, rear one is risen to stir and pushes and maturation.Wherein a rear screw rod is owing to being thereby that isometrical equidistant screw rod makes the insufficient puffed degree that affects maturity and powder delivery of raw material compression.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of for simple in structure, the maturity of self heating shape rice-flour noodles machine and the extruding screw of puffed degree excellent performance.
For achieving the above object, technical scheme provided by the utility model is: a kind of displacement extruding screw, screw thread on described extruding screw is divided into large helical pitch squeezing, maturing section and little helical pitch squeezing, maturing section, and wherein, the pitch of large helical pitch squeezing, maturing section is greater than the pitch of little helical pitch squeezing, maturing section.
The screw thread of described large helical pitch squeezing, maturing section is 1/2nd to 2/3rds of total number of threads.
The screw thread of described little helical pitch squeezing, maturing section is 1/2nd to 1/3rd of total number of threads.
The helical pitch of described large helical pitch squeezing, maturing section is 80 ~ 90mm.
The helical pitch of described little helical pitch squeezing, maturing section is 75 ~ 85mm.
Described little helical pitch squeezing, maturing section is multiple thread mechanism.
The utility model makes by equidistant screw rod is improved that thereby the larger back segment pitch of same screw rod leading portion pitch is less to be made the ground rice slurry form larger compression ratio in airtight slaking barrel to make vermicelli tightr, and slaking and puffed degree are better.
Description of drawings
Fig. 1 is overall structure schematic diagram of the present utility model.
Fig. 2 is the side view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with institute's drawings attached, preferred embodiment of the present utility model is: referring to accompanying drawing 1 and accompanying drawing 2, screw thread on the described displacement extruding screw of the present embodiment is divided into large helical pitch squeezing, maturing section 1 and little helical pitch squeezing, maturing section 2, wherein, the pitch of large helical pitch squeezing, maturing section 1 is greater than the pitch of little helical pitch squeezing, maturing section 2.The described large helical pitch squeezing, maturing section 1 of the present embodiment and little helical pitch squeezing, maturing section 2 respectively account for half of whole screw thread.Wherein, the helical pitch of large helical pitch squeezing, maturing section 1 is 85mm, and the helical pitch of little helical pitch squeezing, maturing section 2 is 75mm.And little helical pitch squeezing, maturing section 2 is multiple thread, and front and back section number of starts is constant.This programme makes by equidistant screw rod is improved that thereby the larger back segment pitch of same screw rod leading portion pitch is less to be made the ground rice slurry form larger compression ratio in airtight slaking barrel to make vermicelli tightr, and slaking and puffed degree are better.
The embodiment of the above is only the preferred embodiment of the utility model, is not to limit practical range of the present utility model with this, therefore the variation that all shapes according to the utility model, principle are done all should be encompassed in protection domain of the present utility model.
