DETAILED DESCRIPTION
[0024] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.
[0025] Example 1
[0026] like Figure 1-Figure 6 As shown, in this embodiment, a solid beverage drying device is provided, including a drying box 1, and two conveyor belts 2 for spreading solid beverages are transversely arranged inside the drying box 1, such as Figure 1 As shown, the two conveyor belts 2 are supported inside the drying box 1 through supporting shafts, and any supporting shaft supporting the conveyor belts 2 can adopt a tubular motor to provide power output for the rotation of the conveyor belts 2. The conveying directions between the two conveyor belts 2 are opposite, and a feed hopper 3 is fixedly installed on one side of the top of the drying box 1, and a discharge mechanism 4 is provided inside the drying box 1 and at the discharge port 301 of the feed hopper 3;
[0027] Among them, a heating box 5 is respectively arranged between the upper layer and the lower layer of the two conveyor belts 2, and the upper side opening of the heating box 5 is close to the lower surface of the upper layer of the corresponding conveyor belt 2. A heating component 6 is arranged inside the drying box 1. The heating component 6 includes a box body, and a heat cavity is arranged inside the box body. The gas in the heat cavity can be heated in the form of a heating pipe. A heating pipe 7 is arranged between the heating component 6 and the two heating boxes 5. The heating pipe 7 is connected to the two heating boxes 5 at the same time. A blower 8 is arranged at the connection position between the heating pipe 7 and the heating component 6. Figure 3 As shown, when the blower 8 is running, the blower 8 introduces the high-temperature gas in the heat chamber into the heating pipe 7. The high-temperature gas is introduced into the heating box 5 through the drainage of the heating pipe 7. The high-temperature gas entering the heating box 5 can heat the upper layer of the conveyor belt 2. In this way, the solid beverage spread on the conveyor belt 2 is heated, which accelerates the evaporation of water in the solid beverage and improves the drying efficiency of the solid beverage.
[0028] The high-temperature gas entering the heating box 5 is discharged into the drying box 1 from the gap between the heating box 5 and the upper layer of the conveyor belt 2, thereby increasing the temperature in the drying box 1, which is beneficial to the drying of the solid beverage.
[0029] like Figure 3 As shown, in order to circulate the gas in the hot chamber of the heating box 5 and the heating component 6, a heat return pipe 9 is provided at one end of the heating box 5 and the heating component 6 away from the heat supply pipe 7. The added heat return pipe 9 can return part of the gas in the heating box 5 to the hot chamber in the heating component 6, thereby promoting the circulation of the gas in the hot chamber of the heating box 5 and the heating component 6, which is beneficial to the recycling of heat.
[0030] like Figure 4 , Figure 5 As shown, in order to be able to transfer the solid beverage in the feed hopper 3 to the conveyor belt 2, the discharge port 301 is opened on one side of the feed hopper 3, and the bottom side wall of the feed hopper 3 is inclined toward the discharge port 301. After the solid drainage is poured into the interior of the feed hopper 3, the solid beverage can slide along the bottom of the feed hopper 3 toward the discharge port 301, so that the solid beverage is discharged from the discharge port 301. The discharge port 301 is located above the uppermost conveyor belt 2. The discharge mechanism 4 includes a blocking plate 401. The blocking plate 401 is slidably connected to the side wall of the feed hopper 3 near the discharge port 301, and a material shifting groove 402 is provided on the side where the blocking plate 401 fits the feed hopper 3. When the material shifting groove 402 is aligned with the discharge port 301, the solid beverage in the feed hopper 3 enters the inside of the material shifting groove 402 from the discharge port 301. When the material shifting groove 402 slides downward and intersects with the discharge port 301, the discharge port 301 is blocked by the blocking plate 401, and the solid beverage in the material shifting groove 402 falls onto the conveyor belt 2.
[0031] like Figure 4 , Figure 5As shown, in order to drive the blocking plate 401 to slide on the side wall of the feed hopper 3, the discharging mechanism 4 also includes a cylinder 403, the cylinder 403 is fixedly mounted on the drying box 1, and the blocking plate 401 is fixedly mounted on the output shaft of the cylinder 403, and the extension direction of the output shaft of the cylinder 403 is the same as the sliding direction of the blocking plate 401. When the cylinder 403 is running, the output shaft of the cylinder 403 can drive the blocking plate 401 to slide back and forth up and down on the side wall of the feed hopper 3.
[0032] like Figure 1 As shown, in order to discharge the moisture in the drying area out of the drying box 1 , an air inlet slot 12 is opened on a side wall of one end of the drying box 1 , and an exhaust fan 13 is arranged on the drying box 1 .
[0033] like Figure 1 , Figure 2 As shown, in order to discharge the dried solid beverage out of the drying box 1 , a discharge hopper 14 is provided on the side wall of the drying box 1 and at the discharge end of the lower conveyor belt 2 .
[0034] Example 2
[0035] like Figure 2-Figure 6 As shown, on the basis of Example 1, in order to speed up the drying efficiency of the solid beverage on the upper conveyor belt 2, a comb plate 10 is fixedly installed inside the drying box 1 in this embodiment, and the comb teeth end of the comb plate 10 is close to the upper surface of the upper conveyor belt 2. When the material shifting groove 402 shifts the solid beverage in the feed hopper 3 onto the upper conveyor belt 2, as the conveyor belt 2 rotates, the solid beverage on the upper conveyor belt 2 is combed and scraped by the comb plate 10, so that the solid beverage is distributed in strips (the solid beverage with strip distribution is formed in the gap between two adjacent comb teeth on the comb plate 10, and the strip distribution is parallel to the conveying direction of the conveyor belt 2) and laid on the conveyor belt 2. In this way, the surface area of the solid beverage becomes larger, the efficiency of water evaporation is improved, and it is beneficial to the drying efficiency of the solid beverage on the upper conveyor belt 2.
[0036] like Figure 2 As shown, in order to guide the solid beverage on the upper conveyor belt 2 to the lower conveyor belt 2, a guide plate 11 is fixedly installed on one side wall of the drying box 1. The guide plate 11 is located on the side of the blanking end of the upper conveyor belt 2. When the solid beverage on the upper conveyor belt 2 falls, the solid beverage will fall on the guide plate 11, and then under the guiding effect of the guide plate 11, the solid beverage will fall on the lower conveyor belt 2, and then pass through the lower conveyor belt 2 for secondary transportation and drying.
[0037] like Figure 6As shown, in order to speed up the drying efficiency of the solid beverage on the lower conveyor belt 2, a plurality of convex ribs 1101 are arranged on the guide plate 11 with intervals. After the solid beverage falls onto the guide plate 11, the convex ribs 1101 are arranged so that the solid beverage slides along the intervals formed by the convex ribs 1101. In this way, the solid beverage falling on the lower conveyor belt 2 is also distributed in strips, and the surface area of the solid beverage becomes larger, thereby improving the efficiency of water evaporation, which is beneficial to the drying efficiency of the solid beverage on the lower conveyor belt 2. 1 and the comb teeth on the comb plate 10 are staggered, each strip-shaped solid beverage on the upper conveyor belt 2 faces a convex rib 1101, and the strip-shaped solid beverage on the upper conveyor belt 2 falls to the guide plate 11. When the solid beverage falls on the convex rib 1101, the convex rib 1101 separates the solid beverage into the intervals on both sides, so that the strip-shaped solid beverage can be turned over, and the turned solid beverage falls on the lower conveyor belt 2, which further improves the efficiency of water evaporation and is beneficial to the drying efficiency of the solid beverage.
