Problems solved by technology

These anti-sticking technologies effectively ensure the continuous rolling process of noodle belts, but they are not effective in increasing the amount of water added to noodle making. At the same time, there are secondary problems such as roller surface wear, food hygiene, and waste of resources in the entire rolling process.

Embodiment 1

[0039] This embodiment provides a special calendering roll for pasta products and its manufacturing method. The stainless steel plate length×width×thickness=594.5×210×1.5 mm is selected, and the surface roughness Ra is 1 μm obtained by grinding. Protrusions with densely packed microspherical structures were prepared on the surface of the substrate by a stamping and stretching process, and the stretching force was 6700N. The protrusions have a diameter of 4.5 mm, a height of 1 mm, and a pitch of 6 mm. The base material with the raised portion was rolled into a cylinder having an outer diameter of 191 mm and a length of 210 mm. Using CO 2 The weld seam is laser welded and the weld seam is ground and polished; the welding parameters are current I=160A, pulse width T=6ms, frequency f=20Hz, and welding speed v=450mm / min. The secondary grinding and polishing treatment ensures the surface finish, Ra0.8μm. Prepare the fluorinated diamond-like carbon film (F-DLC) on the outer surfac...

Embodiment 2

[0041] This example provides a special calender roll for pasta products and its manufacturing method. The stainless steel plate is length×width×thickness=624.5×240×2.0 mm, and the surface roughness Ra is 1 μm obtained by grinding. A stamping and stretching process is used to prepare densely packed protrusions on the surface of the substrate, and the stretching force is 11000N. The protrusions have a diameter of 4.8 mm, a height of 1.3 mm, and a pitch of 7 mm. The base material with the raised portion was rolled into a cylinder with an outer diameter of 201 mm and a length of 240 mm. Electron beam welding (EBW) is used to weld the weld and the weld is ground and polished; the main welding parameters are high voltage 50kV, beam current 20mA, focusing current 1.82~1.83A, line speed v=500mm / min, vacuum degree 3.0×10 -2 Pa. The secondary grinding and polishing treatment ensures the surface finish, Ra 0.8μm. A fluorinated diamond-like carbon film (F-DLC) was prepared on the outer...

Embodiment 3

[0043] This embodiment provides a special calender roll for pasta products and its manufacturing method. The stainless steel plate is length×width×thickness=750.5×300×2.0 mm, and the surface finish is Ra 2 μm after grinding. A stamping and stretching process is used to prepare densely packed protrusions on the surface of the substrate, and the stretching force is 11500N. The protrusions have a diameter of 4.8 mm, a height of 1.5 mm, and a pitch of 7 mm. The base material with the protrusions was rolled into a cylinder with an outer diameter of 240 mm and a length of 300 mm. Welds with CO 2 Laser welding and grinding and polishing of the weld seam; welding parameters are current I=160A, pulse width T=5ms, frequency f=18Hz, welding speed v=450mm / min. The secondary grinding and polishing treatment ensures the surface finish, Ra 1.6μm. The fluorinated diamond-like carbon film (F-DLC) was prepared on the outer surface of the cylinder, the vacuum degree was 1.0Pa, the ratio of ca...

Abstract

The invention discloses a special calendaring roller for flour food products and a manufacturing method thereof, and relates to the technical field of flour food processing equipment. The calendaringroller is in symmetrical arrangement, and comprises a first calendaring roller and a second calendaring roller, wherein the two calendaring rollers have the same structure; the calendaring roller comprises two support shafts; a cylindrical base body is arranged between the two support shafts; a calendaring roller tube body is arranged on the cylindrical base body of the calendaring roller in a sleeving way; protruding parts of micro spherical structures are prepared on the outer surface of the calendaring roller tube body; and a low- surface-energy chemical vapor deposition carbon-based dopingfilm coats the outer surface of the calendaring roller tube body. The invention also provides the manufacturing method of the special calendaring roller for flour food products. The calendaring roller manufactured by the manufacturing method has the advantages that a contact angle between water drips and the surface of the calendaring roller is improved through an element doping film; the adhesion capability of flour belts on the surface of the calendaring roller is reduced; and the water addition quantity of machine made flour food products can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of pasta processing equipment, in particular to a special calendering roller for pasta products and a manufacturing method thereof. Background technique [0002] Flour is mixed with water to make dough, and then rolled by multi-stage calender rolls to form noodle strips with different thicknesses, which is an important process for the industrial production of pasta products such as dried noodles and fresh wet noodles. "Calendering" is a process of simulating hand-made noodles, which can enhance the strength and toughness of gluten and make the dough tissue connection more dense. Calendering rollers are the key components to realize this process. At present, the amount of water added to handmade noodles is usually more than 50%, while the amount of water added to machine-made noodles is only 30% to 35%. This is because the rolling process and increasing the amount of water added will increase the proportion o...
