Technical Field
[0001] The utility model relates to the technical field of stevioside processing, in particular to a drying device for stevioside processing. Background Art
[0002] Stevioside, also known as stevioside or steviol glycoside, is a natural sweetener extracted from the leaves of the Stevia rebaudiana plant of the Asteraceae family. It has the characteristics of high sweetness and low caloric energy. After stevioside is made into a white or slightly yellow loose powder, it is often necessary to dry the finished product through a drying equipment to remove the water vapor in the finished product to facilitate the subsequent storage of the finished product. However, when the finished product is dried through the drying equipment, the finished product is poured into the interior of a vacuum dryer, first dried, and then the water vapor inside the dryer is extracted to accelerate the evaporation of water to achieve the drying of the finished product. However, since the finished product is in a static state during the drying process, although the water vapor on the upper end of the finished product is easily dried and discharged, the water vapor accumulated at the lower end of the finished product is difficult to discharge due to the blockage of the upper end, resulting in the formation of water vapor agglomeration inside the finished product, which greatly reduces the drying effect of the finished product. Therefore, we propose a drying equipment for stevioside processing to solve the above problem. Utility Model Content

[0022] like Figure 4 and Figure 5As shown, in another embodiment of the present invention, the auxiliary mechanism 8 includes a movable frame 801, which is movably installed in the interior of the placement box 6, and the lower surface of the movable frame 801 is in contact with the inner lower surface of the placement box 6, and the upper ends of the front and rear sides of the placement box 6 are respectively installed with slide rails 803, and the front and rear ends of the movable frame 801 are respectively installed with sliders 802, and the sliders 802 are respectively installed on the slide rails 803, and the upper surface of the sealing cover 7 is penetrated by a plurality of exhaust grooves 804, and the interior of the exhaust grooves 804 is respectively installed with filter screens 805, and the upper ends of the movable frame 801 are respectively in contact with the lower surfaces of the sealing cover 7 and the filter screen 805, and the lower surface of the placement box 6 is provided with a guide groove 806, and a movable plate 807 is movably installed in the middle of the guide groove 806, and guide rods 808 are respectively installed at the front and rear ends of the guide groove 806, and the rod bodies of the guide rods 808 are respectively movably penetrated and installed in the movable frame 801. The lower end of the pull rope 810 is movably installed in the guide groove 806 and is connected to the movable plate 807. The outer side of the pull rope 810 is sleeved with a rubber sleeve. The rear end of the interior of the drying box 1 is movably installed with a rotating frame 811. The rear side of the placing box 6 is installed with an extension block 812. The extension block 812 is engaged and installed in the interior of the rotating frame 811. A positioning rod 813 is engaged and installed between the rotating frame 811 and the extension block 812. A number one gear 814 is installed on the rear side of the rotating frame 811. A motor 815 is installed at the lower end of the rear side of the drying box 1. A number two gear 816 is installed at the output end of the motor 815. The number two gear 816 is meshed with the number one gear 814.
[0023] The user pours the finished product into the placement box 6, and then installs the sealing cover 7 so that the sealing cover 7 and the placement box 6 form a whole. Then the user puts the placement box 6 into the interior of the drying box 1. At the same time, the placement box 6 will drive the extension block 812 to insert into the interior of the rotating frame 811. Then, after the placement of the placement box 6 is completed, the positioning rod 813 is inserted between the overlapping extension block 812 and the rotating frame 811 for positioning. Then the user can close the sealing door 2 and start the heater 5 and the motor 815 to allow the heater 5 to heat the finished product inside the placement box 6. At the same time, the motor 815 will drive the second gear 816 to rotate repeatedly at an angle of 30° forward and backward. Then the second gear 816 can drive the rotating frame 811 and the extension block 812 to rotate through the first gear 814. Then the extension block 812 can drive the placement box 6 to rotate at an angle of 30° forward and backward. Therefore, when the placement box 6 rotates, the finished product inside the placement box 6 can flow, thereby preliminarily improving the drying efficiency of the finished product. At the same time, when the placement box 6 is placed, When the box 6 rotates, the counterweight 809 drives the movable plate 807 to move downward along the guide rod 808. At the same time, the counterweight 809 pulls the pull rope 810 to move while moving, so that the pull rope 810 drives the movable frame 801 to cooperate with the slider 802 and the slide rail 803 to move upward, so that the movable frame 801 can scrape and flip the finished products flowing downward, which can prevent the finished products from sticking to the inner surface of the box 6 and make it easier for the flipped finished products to be dried out. The box 6 is continuously rotated back and forth, and the counterweight 809 can continuously drive the movable frame 801 to move, so as to assist the drying of the finished products. The dried water vapor can then enter the interior of the drying box 1 through the exhaust slot 804, and finally the water vapor inside the drying box 1 can be sucked out by the vacuum suction pump 3 to achieve the drying of the finished products. Finally, after the finished products are dried, the user can open the sealed door 2, then remove the positioning rod 813, and finally the user can take out the box 6 to recycle the finished products.
[0024] The filter 805 installed inside the exhaust groove 804 is used to block the finished products flowing inside the placement box 6 to prevent the finished products from leaking into the drying box 1. At the same time, during the movement of the movable frame 801, the products in contact with the lower surface of the filter 805 will be scraped and cleaned to avoid blockage between the product and the filter 805, which will cause the water vapor to be unable to be discharged normally.
[0025] The working principle of this drying equipment for stevioside processing:
[0026] When in use, the user first pours the finished product into the placement box 6, and then installs the sealing cover 7 so that the sealing cover 7 and the placement box 6 form a whole. Then, the user puts the placement box 6 into the interior of the drying box 1. At the same time, the placement box 6 will drive the extension block 812 to insert into the interior of the rotating frame 811. Then, after the placement of the placement box 6 is completed, the positioning rod 813 is inserted between the overlapping extension block 812 and the rotating frame 811 for positioning. Then, the user can close the sealing door 2 and start the heater 5 and the motor 815 to allow the heater 5 to heat the finished product inside the placement box 6. At the same time, the motor 815 will drive the second gear 816 to rotate repeatedly at an angle of 30° forward and backward. Then, the second gear 816 can drive the rotating frame 811 and the extension block 812 to rotate through the first gear 814. Then, the extension block 812 can drive the placement box 6 to rotate at an angle of 30° forward and backward. Therefore, when the placement box 6 rotates, the finished product inside the placement box 6 can flow, thereby preliminarily improving the drying efficiency of the finished product. When the placing box 6 rotates, the counterweight block 809 will drive the movable plate 807 to move downward along the guide rod 808. At the same time, the counterweight block 809 pulls the pull rope 810 to move when moving, so that the pull rope 810 drives the movable frame 801 to cooperate with the slider 802 and the slide rail 803 to move upward, so that the movable frame 801 can scrape and flip the finished products flowing downward, which can prevent the finished products from sticking to the inner surface of the placing box 6 and make it easier to dry out the moisture of the flipped finished products. The placing box 6 continuously rotates back and forth, and the counterweight block 809 can continuously drive the movable frame 801 to move to assist in the drying of the finished products. Then the dried water vapor can enter the interior of the drying box 1 through the exhaust groove 804, and finally the water vapor inside the drying box 1 can be sucked out by the vacuum suction pump 3 to achieve the drying of the finished products. Finally, after the finished products are dried, the user can open the sealing door 2, then remove the positioning rod 813, and finally the user can take out the placing box 6 to recycle the finished products.

For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
