Abstract
The present invention relates to a kind of food machinery, disclose especially a kind of moulding pair roller of justifying Bun shaping machine. The moulding pair roller of this circle Bun shaping machine, is characterized in that: described moulding pair roller, by food-grade polypropylene Material Addition look mother and antioxidant, mixes rear once injection moulding and makes. The present invention applies up-to-date food grade polypropylene material, once injection moulding, have than the more competitive advantage of rub resistance of general aluminium roller, have more that splendid smoothness, environmental protection are recyclable, the advantage such as acid and alkali-resistance, easy to clean, cleaning, antibiotic property, anti-pollution and scratch-resistant, have broad application prospects in food machinery field.
Description
(1) technical field
The present invention relates to a kind of food machinery, particularly a kind of moulding pair roller of justifying Bun shaping machine.
(2) background technology
Steamed bun is a kind of popular food, is especially subject to northern broad masses' welcome. At present, employing is right mostly to produce steamed bunRoll-type steamed bun making machine, the pair roller wherein using mostly is aluminium matter, because the matter of aluminum is soft, in steamed bun production process, its pair rollerMoulding is bad, easily adhesion, and difficult cleaning, easily causes heavy metal pollution and antistick layer to come off, and finally affects the Forming Quality of steamed bun.
(3) summary of the invention
The present invention is in order to make up the deficiencies in the prior art, and a kind of corrosion-resistant, easy to clean, best bright finish, nontoxic nothing are providedThe moulding pair roller of the round Bun shaping machine polluting.
The present invention is achieved through the following technical solutions:
A moulding pair roller of justifying Bun shaping machine, is characterized in that: described moulding pair roller is by food-grade polypropylene materialAdd look mother and antioxidant, mix rear once injection moulding and make.
Polypropylene is the another fine resin kind of development after nylon, is a kind of high density, unprotected side chain, high crystallization mustLinear polymer, there is good combination property. Polypropylene is white in color translucent when not painted, wax-like, lighter than polyethylene, thoroughlyLightness is also good compared with polyethylene, firmer than polyethylene; Material performance density is little, and it is poly-that intensity and toughness, hardness heat resistance are all better than low pressureEthene, can use in 100 about degree, have good electrical property, and its high-frequency insulation performance is not subject to humidity effect, is suitable for makingCommon mechanical part, corrosion-resistant part and insulating part.
More excellent scheme of the present invention is:
The raw material melt flow rate of described moulding pair roller is 10g/10min, and density is 0.9g/cm3, moulding pair roller lackMouth impact strength is 8, and elongation at break is 600%, and bending strength is 25MPa.
The present invention applies up-to-date food grade polypropylene material, and once injection moulding has than more rub resistance of general aluminium rollerCompetitive advantage, have more that splendid smoothness, environmental protection are recyclable, acid and alkali-resistance, easy to clean, cleaning, antibiotic property, anti-pollution andThe advantages such as scratch-resistant, have broad application prospects in food machinery field.
(4) detailed description of the invention
Embodiment:
(1) the present invention is the improvement to current material, is first to use food-grade polypropylene (B4808) material, adds suitableAmount look mother and antioxidant, once injection moulding.
(2) important parameter:
Melt flow rate (MFR): 10g/10min,
Density: 0.9g/cm3，
Notched Izod impact strength: 8,
Elongation at break: 600%,
Bending strength: 25MPa.
(3) processability
Crystallization material, hygroscopicity is little, easily melts body and breaks, and contacts for a long time easily decompose with thermometal.
Good fluidity, but contraction scope and shrinkage value are large, and shrinkage cavity easily occurs. indenture, distortion.
Cooling velocity is fast, and running gate system and cooling system should slowly dispel the heat, and notes controlling forming temperature. the low direction of material temperatureDirectionality is obvious. and especially obvious when cryogenic high pressure, when mold temperature is spent lower than 50, plastic is rough, easily produces welding bad, staysTrace, the above easily generation of 90 degree buckling deformation.
Plastics wall thickness must evenly, be avoided starved, and wedge angle, in case stress is concentrated.
(4) polypropylene (B4808) resin has good mechanical performance and heat resistance, serviceability temperature scope-30 DEG C～140 DEG C. Have good electrical insulation capability and chemical stability, water suction, contacts not with most chemicals hardly simultaneouslyHave an effect. This product is corrosion-resistant, tensile strength 30MPa, and intensity, rigidity and the transparency are all good than polyethylene; Shortcoming is low temperature resistantImpact is poor, more aging, but can be overcome by modification and interpolation antioxidant respectively.
Claims (1)
1. a moulding pair roller of justifying Bun shaping machine, is characterized in that: described moulding pair roller is by food stage B4808 polypropylene materialMaterial adds look mother and antioxidant, mixes rear once injection moulding and makes; By food stage B4808 polypropylene material, look motherWith the raw material melt flow rate of the moulding pair roller of antioxidant composition be 10g/10min, density is 0.9g/cm3, moulding pair rollerNotched Izod impact strength is 8, and elongation at break is 600%, and bending strength is 25MPa.
