Description

Technical Field

[0001] The present invention relates to the field of food processing, and in particular to a preparation device and a preparation method of a drawn mochi filling. Background Art

[0002] Freeze-resistant and bake-resistant stringy mochi filling is a mochi filling that is suitable for freezing and baking and has a stringy effect. Mochi is a traditional Asian delicacy typically made from glutinous rice flour or glutinous rice. Unlike traditional mochi, this filling may be able to withstand the baking process without losing its characteristics due to high temperatures. Therefore, a mochi filling preparation device is needed.

[0003] The preparation device introduces high-temperature steam during the stirring process, heating the mixture of powder and water while stirring until it becomes a mature mixture before proceeding to further processing. This prevents inconsistent maturity between the surface and the interior of the food, which can lead to defects such as aging, cracking, and lack of elasticity. However, excessively high temperatures within the preparation device can cause excessive gelatinization of the mochi filling. Therefore, real-time monitoring of the internal temperature of the preparation device is necessary. Inconsistent temperatures within the preparation device can lead to uneven heating of the mixture, affecting the production quality of the mochi filling. Summary of the Invention

The rotation of the second motor drives the threaded rod to rotate, and the air intake hose can be moved to a position above the lower temperature to increase the heating effect and avoid quality problems of the mochi filling caused by uneven heating. When the temperature probe detects that the temperature inside the refining barrel continues to rise, the excessively high temperature may cause excessive gelatinization of the mochi filling. At this time, the cooling fan is started to cool the refining barrel. BRIEF DESCRIPTION OF THE DRAWINGS

A fixedly connected steam heating pipe 156 and a pressure gauge 157 are symmetrically provided on the top of the sealing cover 15. A fixedly connected first motor 122 is installed in the first control box 12. The output shaft of the first motor 122 is fixedly connected to the outer wall of the refining barrel 2. The rotation of the first motor 122 drives the refining barrel 2 to rotate. When the drawn mochi filling inside the refining barrel 2 is heated and gelatinized, the refining barrel 2 can be turned over, and the drawn mochi filling can be poured out and packaged through the packaging machine.

[0028] The two opposite side walls of the refining barrel 2 are symmetrically provided with fixed blocks 21 fixedly connected. The fixed blocks 21 are located in the upper half of the refining barrel 2. The side walls of the fixed blocks 21 are provided with limit grooves 22. When all the premixed materials are poured into the refining barrel 2, the sealing cover 15 is rotated to the top of the refining barrel 2 for sealing. The limit blocks 155 slide into the limit grooves 22 to limit the sealing cover 15, thereby ensuring the sealing effect of the refining barrel 2.

[0029] A rotatable threaded rod 23 is provided in the refining barrel 2, and the threaded rod 23 is located in the upper half of the refining barrel 2.

[0030] A rotatable stirring mechanism 3 is provided in the refining vat 2. The stirring mechanism 3 includes a rotatable stirring shaft 31. A third motor 131 is fixedly installed in the second control box 13. The output end of the third motor 131 is provided with a fixed stirring shaft 31. The stirring shaft 31 passes through the refining vat 2 and extends into the interior of the refining vat 2. The stirring shaft 31 is rotatably connected to the refining vat 2. The interior of the stirring shaft 31 is hollow. A fixed reciprocating screw 33 is provided at the center of the interior of the stirring shaft 31. The rotation of the stirring shaft 31 drives the reciprocating screw 33 to rotate.

[0031] A rotatably connected guide column 331 is provided inside the stirring shaft 31, and the other end of the guide column 331 is fixedly connected to the inner wall of the refining barrel 2. A threaded second slider 332 is provided on the reciprocating screw 33. The guide column 331 guides the second slider 332. The rotation of the reciprocating screw 33 drives the second slider 332 to reciprocate along the guide column 331. The outer wall of the second slider 332 is provided with a fixedly connected convex strip 333, and the upper and lower ends of the convex strip 333 are provided with inclined surfaces.

[0032] The inner wall of the stirring shaft 31 is evenly provided with a fixedly connected telescopic spring 32, and the other end of the telescopic spring 32 is provided with a fixedly connected wedge block 321. The side wall of the wedge block 321 close to the inner wall of the stirring shaft 31 is provided with a fixedly connected temperature measuring probe 322. The convex strip 333 moves to squeeze the wedge block 321, and the wedge block 321 moves toward the inner wall of the stirring shaft 31. The temperature measuring probe 322 contacts the inner wall of the stirring shaft 31, which can measure the internal temperature of the refining barrel 2 and detect the uniformity of heating inside the refining barrel 2, thereby preventing the internal temperature of the refining barrel 2 from being too high and affecting the quality of the drawn mochi filling.

[0033] The outer wall of the stirring shaft 31 is fixed with a first stirring arm 34 distributed in an array, and a fixedly connected connecting column 35 is provided between the first stirring arms 34. A slidable second stirring arm 341 is provided at the end of the first stirring arm 34, and a fixedly connected tension spring rod 342 is provided on the inner wall of the first stirring arm 34. The telescopic end of the tension spring rod 342 is fixedly connected to the second stirring arm 341, wherein the top of the second stirring arm 341 near the first motor 122 and the third motor 131 is provided with a fixedly connected first scraper 343, and the bottom of the second stirring arm 341 near the center of the stirring shaft 31 is provided with a fixedly connected second scraper 344. The first scraper 343 and the second scraper 344 can scrape off the stretched mochi filling attached to the inner wall of the refining barrel 2 while stirring the stretched mochi filling.

[0034] A method for preparing a device for preparing drawn mochi filling comprises the following steps: When using, the operator prepares 50%-55% sugar, 25%-30% drinking water, 13%-18% starch, 2%-5% vegetable oil, 1%-5% glutinous rice flour, 0.1%-0.4% colloid, 0.1%-0.3% salt, 0.1%-0.3% emulsifier, 0.002%-0.2% enzyme, and other additives. First, put the liquid materials (except vegetable oil) into the mixing tank and stir evenly, then put the powder materials (colloid, salt, emulsifier, enzyme, starch, glutinous rice flour, sugar, etc.) into the mixing tank in turn and stir evenly; The premixed material is then fed into the interior of the refining drum 2 through the feed rotor pump and pipeline. The hydraulic rod 142 is stretched to drive the sealing cover 15 to rotate. The sealing cover 15 rotates to the top of the refining drum 2 to seal. The limit block 155 slides into the limit groove 22 to limit the sealing cover 15, ensuring the sealing effect of the refining drum 2. Then, the steam entering through the steam heating pipe 156 and the air inlet hose 25 heats the interior of the refining drum 2. The third motor 131 is started, and the rotation of the third motor 131 drives the stirring shaft 31. The elastically connected second stirring arm 341 can stir the premixed material more thoroughly. The rotation of the stirring shaft 31 drives the reciprocating screw 33 to rotate, and the second slider 332 also reciprocates along the guide column 331. When the inclined surface of the ridge 333 on the outer wall of the second slider 332 contacts the wedge block 321, the second slider 332 continues to move. The ridge 333 on the outer wall of the second slider 332 squeezes the wedge block 321, and the wedge block 321 moves toward the inner wall of the stirring shaft 31. The temperature probe 322 contacts the inner wall of the stirring shaft 31 to measure the temperature inside the refining barrel 2. The evenly distributed wedge blocks 321 can detect the temperature at different locations. When the temperature difference between the temperature measuring probes 322 is too large, it indicates that there may be uneven heating inside the refining barrel 2. At this time, the second motor 26 is started. The rotation of the second motor 26 drives the threaded rod 23 to rotate, and the air intake hose 25 can be moved to a position with lower temperature, thereby increasing the heating effect and avoiding quality problems of the mochi filling caused by uneven heating. When the temperature probe 322 detects that the temperature inside the refining barrel 2 continues to rise, the excessively high temperature may cause excessive gelatinization of the mochi filling. At this time, the cooling fan 111 is started to cool the refining barrel 2. When the mochi filling inside the refining barrel 2 is processed, the third motor 131 is turned off to stop stirring the mochi filling. The hydraulic rod 142 is compressed to drive the sealing cover 15 to rotate, the refining barrel 2 is opened, and the first motor 122 is started. The rotation of the first motor 122 drives the refining barrel 2 to rotate, and the drawn mochi filling is poured out and packaged through the packaging machine.

[0035] From the above description, it can be seen that the above embodiment of the present invention is provided with a plurality of detachable temperature measuring probes 322 to detect the internal temperature of the refining barrel 2, thereby avoiding quality problems of the mochi filling caused by uneven heating. At the same time, it prevents excessive gelatinization of the mochi filling caused by excessive temperature, and the elastically connected second stirring arm 341 can stir the premixed material more fully.

[0036] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
