Description

Technical Field

[0001] The utility model belongs to the field of food processing technology equipment, and more specifically relates to a dough rolling and kneading composite flattening machine, which is used in the composite calendering technology stage of high-water-added noodle product processing. Background Art

[0002] Industrialized production is the main development trend of the pasta processing industry, and dough band compounding is an important process link in pasta production. Only under the rolling action of rollers can the loose and scattered gluten of dough or dough after kneading form a continuous network structure, forming a dough band with a certain toughness and strength. Dough band compounding is the process of compounding the dough band formed in the previous process from two layers into one layer. The traditional dough band compounding method is generally only suitable for compounding with lower moisture content, with high calendering strength and lack of the kneading and beating action of manual dough making. It has little effect on improving the quality and taste of noodles, and there is still a significant gap compared to hand-rolled noodles. The high-quality dough band compounding of high-moisture dough or noodles is also a difficult problem faced by existing technologies. Utility Model Content

[0003] In view of the fact that traditional dough band compounding is only suitable for compounding with low moisture content and lacks the kneading and beating effects of manual dough making, the utility model provides a dough band rolling and kneading compound flattening machine, which draws on and imitates the traditional manual dough making method, incorporates the rolling and kneading technology into the processing, imitates the kneading and beating effects of manual dough making, improves the gluten network structure in the dough band, promotes the elasticity and tensile strength of the gluten network, and enhances the quality of the dough band. Flattening creates favorable conditions for the subsequent dough band proofing.

[0012] The technical solution of this utility model has the following advantages:

[0013] A. The dough sheet rolling and kneading composite flattening machine provided by the utility model draws on the manual dough kneading method. Through the extrusion cooperation of radial corrugated sticks and axial corrugated rollers, the double-layer dough sheet is rolled at a calendering ratio of about 40%.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figure 1 and Figure 2 As shown, the utility model provides a dough sheet rolling and compounding flattening machine, comprising a frame 13 and a radial corrugated roller 1, an axial corrugated roller 3 and a flattening roller group 8 arranged in parallel on the frame 13, the circumferential surface of the radial corrugated roller 1 is provided with radial corrugations, and the circumferential surface of the axial corrugated roller 3 is provided with axial corrugations arranged in an axial direction, the two are arranged opposite to each other and rotate in opposite directions, and a rolling gap a is formed between the radial corrugated roller 1 and the axial corrugated roller 3 for the composite dough sheet 11 to pass through; the flattening roller group 8 is arranged below the radial corrugated roller 1 and the axial corrugated roller 3, and comprises a flattening roller I81 and a flattening roller II82, the two form a flattening gap b, and rotate in opposite directions.

[0023] For example: the radial corrugation roller 1 has a diameter of 180 mm, a length of 550 mm, and a curved surface radius of 18 mm; the axial corrugation roller 3 has a diameter of 180 mm, a length of 550 mm, and a curved surface radius of 18 mm, and is used to roll and knead the double-layer composite dough strip; the rolling roller I and the rolling roller II are preferably cylindrical pressure rollers with smooth surfaces, and the diameter of the two rolling rollers is preferably 180 mm and the length is preferably 550 mm, and the dough strip with longitudinal and transverse corrugations after compounding is flattened.

[0024] The present invention comprises two sets of calendering rollers, wherein the radial corrugating roller 1 and the axial corrugating roller 3 form one set of calendering rollers, and the flattening roller set forms the second set of calendering rollers. The two sets of calendering rollers are arranged in an upper and lower position. The radial corrugating roller 1 and the axial corrugating roller 3 are preferably located on the upper portion of the frame 1, with the radial corrugating roller 1 located above the axial corrugating roller 3, and the flattening roller set 8 located below the frame 1.

[0025] The radial corrugating roller 1 and the axial corrugating roller 3 are connected by a drive motor I9, while the flattening roller assembly 8 is connected by a drive motor II10. Drive motor I9 is ​​equipped with an encoder I5, while drive motor II10 is equipped with an encoder II6. Drive motors I9 and II10 are preferably variable-frequency motors. The speed of drive motor I9 is ​​calculated and controlled based on the speed signal of the preceding composite dough sheet; the speed of drive motor II10 is calculated and controlled based on the signal from encoder I5.

[0026] As a further preferred embodiment of the present invention, an anti-accumulation pressure roller 4 is provided in the inlet area formed above the radial corrugating roller 1 and the axial corrugating roller 3.
