[0042] The related setting of the rolling rollers 20 is as follows:

[0043] Specifically, the rolling rollers 20 are made of materials that can quickly transfer heat and are resistant to burning, such as metal materials.

[0044] Specifically, the two ends of the rolling rollers 20 are rotatably arranged on the combustion furnace 10 through bearings.

[0045] The related setting of the combustion furnace 10 is as follows:

[0046] Specifically, for the feeding port:

[0047] In the optional scheme of the embodiment, preferably, as shown in Figure 1 and Figure 2As shown, the feed inlet is provided with a furnace door 13, which is rotatably connected between the side wall of the combustion furnace 10 by at least one rotating part, and the furnace door 13 can close the feed inlet. Closing the feed inlet can reduce the amount of external air entering, thereby adjusting the speed and intensity of combustion; and can guide the flow of gas in the combustion furnace 10, that is, the air below the grid 17 enters and is discharged from the smoke outlet; closing the feed inlet can reduce the interference of external factors on the combustion environment inside the combustion furnace 10, and ensure the stability of combustion; and closing the feed inlet can reduce the heat loss in the combustion furnace 10, improve the energy utilization efficiency, and make the heat in the combustion furnace 10 more concentratedly act on the rolling roller 20 and the fresh grass fruit, thereby improving the drying efficiency.

The smoke outlet is arranged opposite to the feed inlet, and the upper edge of the smoke inlet of the smoke exhaust channel 12 is away from the inner side wall of the feed inlet with a larger interval, and the lower edge is away from the inner side wall with a smaller interval. This structure is beneficial to the rapid entry of hot waste gas near the rolling roller 20 into the smoke exhaust channel 12, and does not accumulate in the furnace, which can cause poor drying effect of the grass fruit, improve the efficiency of waste gas exhaust, and thus ensure the combustion effect in the combustion furnace 10 and the drying efficiency of the grass fruit; the inclined guide surface 123 can accelerate the flow of hot waste gas, so that the waste gas moves more smoothly in the direction of the smoke outlet.

[0051] In the optional solution of the embodiment, preferably, the inner two sides of the smoke exhaust channel 12 are tapered from the smoke inlet to the upper opening. The tapered design makes the cross-sectional area of the smoke exhaust channel 12 gradually decrease from the smoke inlet to the upper opening. According to the principle of fluid mechanics, the flow rate of fluid increases when it passes through a tapered channel. Therefore, the flow rate of hot exhaust gas in the smoke exhaust channel 12 increases as the channel narrows; the tapered smoke exhaust channel 12 forms a certain negative pressure at the smoke inlet during operation. This negative pressure effect can enhance the suction effect on the exhaust gas in the combustion furnace 10, and facilitate the smooth entry of exhaust gas into the smoke exhaust channel 12.

[0055] Specifically, the protective plate 15 can be made of reinforced tempered glass.

[0056] Specifically, for the outer side wall of the combustion furnace 10:

[0057] In the optional solution of the embodiment, preferably, an aluminum silicate insulation fiber layer is arranged on the outer side wall of the combustion furnace 10.

[0061] Specifically, the driver 30 can be a rotating handle, which is driven by manpower at this time; the driver 30 can also be a driving motor, and the output shaft of the driving motor is fixedly connected with the driving gear 31, so that the driving motor drives the driving gear 31 to rotate.

[0062] Specifically, in order to improve the intelligent setting, a controller can also be arranged, which is in communication connection with the driver 30 and controls the rotation effect of the driver 30 at different rotating speeds, such as different high and low speed gears arranged on the controller.

[0063] Wherein, the other relevant settings are described as follows:

The top of the combustion material containing cavity 11 is a position close to the bottom of the rolling roller 20, and the temperature of this area plays a crucial role in the drying process of the fresh grass fruits placed on the rolling roller 20. The sensing probe 41 of the high-temperature thermometer 40 is extended to this position, so that the temperature closest to the heat source for drying the grass fruits can be directly measured; the high-temperature thermometer 40 monitors the temperature of the top of the combustion material containing cavity 11 in real time, so as to provide accurate temperature data for the operator, which can help the operator to understand the running state of the combustion furnace 10 and ensure that the equipment runs in a safe and effective drying temperature range.

Here, the fuel refers to any agricultural and forestry waste that can be picked up on site, which meets the fuel demand, and the type of fuel is not limited. After the above operation, ignite the fuel, push the furnace door handle 131 and half close the furnace door 13, then keep the fuel burning all the time. Five minutes after the fuel is ignited, the contact between each rolling roller 20 and the fuel is completed, and then the fresh grass fruit is evenly placed on each rolling roller 20. Since the fuel releases a large amount of heat, the rolling roller 20 is heated and transfers heat to the fresh grass fruit. Under the action of the driver 30, each rolling roller 20 rotates. The operator observes the high-temperature thermometer 40, controls the fuel burning condition, and adjusts the temperature to keep it at 150℃-180℃. After ten minutes of baking process, pay attention to the color, aroma and touch of the grass fruit. The grass fruit changes from green to brown with oil, gradually emits a unique aroma, and the touch changes to dry and hollow sound when tapped. This indicates that the grass fruit baking is completed, and the grass fruit on each rolling roller 20 can be collected and stored, and the next batch of fresh grass fruit drying work or the drying work can be started.

[0070] When the drying work is completed, the fuel on the grid 17 can be physically extinguished after it is completely burned out. The combustion furnace 10 is placed until the surface temperature of each rolling roller 20 returns to room temperature. The in-situ fresh grass fruit dryer 100 should be placed in a dry environment during non-working period, and high-temperature fire-resistant anti-rust paint should be brushed regularly to prolong its service life.
