Description

Technical Field

[0001] The utility model relates to the technical field of pepper roasting ovens, in particular to a pepper roasting oven. Background Art

[0002] Chili paste is a favorite condiment in the southwest region. The traditional method of making it is to roast the dried chilies to make them crisp and fragrant, and then crush them into a dipping sauce. Therefore, a roasting device is needed to dry the chilies.

[0003] A search revealed a Chinese utility model patent with the authorization publication number CN 209995319U, which discloses a chili roasting device. The description states that when roasting chili peppers, the chili peppers are placed in a rolling spiral inner container, where biomass fuel is burned in the flame combustion chamber to generate flames. The exhaust fan is activated, and under the action of the exhaust fan, an airflow from bottom to top is generated in the cavity. The flame in the flame combustion chamber enters the top of the cavity along with the airflow, and contacts the chili peppers through the flame holes in the rolling spiral inner container, roasting the chili peppers. Simultaneously, the exhaust fan draws the smoke in the cavity along a conduit into water, which dissolves the dust in the smoke. The smoke then passes through the exhaust hole and comes into contact with a gas purifier in the exhaust hole. The gas purifier removes pungent gases and dust from the smoke, and the smoke is finally discharged into the air.

[0004] However, the pepper roasting device in the above patent has the following problems: (1) the peppers need to be manually added into the oven, resulting in low pepper feeding efficiency; (2) the hot air enters the casing, and the peppers enter the rolling spiral inner container. After the peppers enter the rolling spiral inner container, they will accumulate in the inner container. Even if the inner container rotates, some peppers will still be concentrated in the center of the pepper pile and are difficult to disperse outward, resulting in uneven roasting; and after the hot air enters the casing, the exhaust fan will quickly draw a large amount of hot air out of the casing, resulting in a short time for the hot air to stay in the casing, and low drying efficiency and effect.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] (1) The peppers are transported upward by a belt conveyor. When the peppers reach the top of the belt conveyor, they fall into the feed box, thereby realizing automatic loading of the peppers and improving loading efficiency.

[0022] (2) Hot air enters the inner container through the air inlet pipe, and the peppers enter the drying drum. The driving mechanism controls the rotation of the drying drum, so that the peppers are evenly distributed around the outer periphery of the inner container. The hot air is blown to the peppers around the inner container through the through-holes of the inner container, thereby achieving uniform drying of the peppers. In addition, the hot air first enters the inner container through the air inlet pipe and then blows outward from the inner container, which increases the path for the hot air to be discharged, thereby increasing the time the heat stays in the drying drum and improving the drying efficiency and effect.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0029] Example 1

[0030] See also Figure 1-4 A chili roasting oven includes an upwardly inclined belt conveyor 1, with a feed box 2 provided below the upper discharge end of the belt conveyor 1. Specifically, discharge hoppers 11 are connected to both sides of the upper end of the belt conveyor 1, and a feed hopper 12 is connected to the upper end of the feed box 2, which is located below the discharge hopper 11. Chili peppers are conveyed upward by the belt conveyor 1. When the chili peppers reach the upper end, they fall downward along the discharge hopper 11 into the feed hopper 12 and enter the feed box 2.

[0031] A downwardly inclined feed port 3 is provided in the feed box 2, and a bracket 4 is provided on one side of the feed box. A support platform 5 is fixed to the end of the bracket 4 away from the feed box. An inclined drying cylinder 7 is rotatably connected to the support platform 5 through a rotary bearing 6. One end of the drying cylinder 7 is closed and the other end is open. The open end of the drying cylinder 7 is rotatably connected to the feed port 3 through a rotary bearing 6, and the opening of the drying cylinder 7 is docked with the feed port 3. An inner liner 8 is connected to the drying cylinder 7 through an annular seat. Specifically, the annular seat includes a fixing ring 21 and several connecting rods 22 connected to the outer wall of the fixing ring. The inner liner 8 is connected to the fixing ring 21, and the connecting rod 22 is connected to the inner wall of the drying cylinder 7. The inner liner can be fixed in the drying cylinder through the annular seat without hindering the circulation of heat. The inner liner 8 is provided with a plurality of through holes 9 on the side wall along its length direction. One end of the inner liner 8 is connected to an air inlet pipe 10, which passes through the sealed end of the drying cylinder 7, and the passing end is used to connect to the combustion chamber. The upper end of the drying cylinder 7 is connected to an air outlet pipe 20, which is used to connect to an exhaust fan to extract the smoke in the drying cylinder through the exhaust fan.

[0032] The bracket 4 is equipped with a drive mechanism that rotates the drying drum 7. Specifically, the drive mechanism includes a mounting platform 13 mounted on the bracket, a motor 14 mounted on the mounting platform, a transmission shaft connected to the motor via a coupling, a main gear 15 connected to the transmission shaft, and a sub-gear 16 connected to the drying drum. The main gear 15 and sub-gear 16 mesh with each other. Starting the motor 14 rotates the transmission shaft, which, through the cooperation of the main gear 15 and sub-gear 16, rotates the drying drum 7, thereby spreading the peppers and achieving uniform heating.

[0033] The drying drum 7 has a discharge port 17 at its lower portion, near one end of the air inlet pipe. A door panel 18 is hingedly connected to the discharge port 17. The upper end of the door panel 18 is locked to the drying drum 7 via a lock. A high-temperature-resistant rubber plug 19 is attached to the inner side of the door panel 18, sealing the discharge port 17. During drying, the rubber plug 19 maintains the seal of the drying drum 7 and prevents heat leakage. The rubber plug 19 can be made of a high-temperature-resistant, food-grade rubber material, such as a food-grade, high-temperature-resistant silicone tube. When the peppers are dried, the door panel 18 can be opened to remove them from the drying drum 7.

[0034] The working principle of this embodiment is:

[0035] The peppers are conveyed upward by a belt conveyor 1. When they reach the top of the belt conveyor 1, they pass through a discharge hopper 11 into a feed hopper 12, then into a feed box 2. They then enter a drying drum 7 through a feed port 3. Because the drying drum 7 is tilted, the peppers slide downward along the drying drum 7. The drive mechanism then controls the rotation of the drying drum 7, evenly distributing the peppers along the inner liner 8. Hot air from the combustion chamber then enters the inner liner 8 and is blown toward the outer peppers through holes 9 therein, completing the roasting process. During the roasting process, smoke is exhausted through an exhaust pipe 20. After roasting is complete, the door panel 18 is opened and the peppers can be removed.

[0036] Example 2

[0037] This embodiment differs from the first embodiment in that sealing rings are provided at the connection between the air inlet pipe 10 and the drying drum 7, and at the connection between the air outlet pipe 20 and the drying drum 7. The sealing rings can improve the sealing performance of the connection between the air inlet pipe 10 and the drying drum 7, and the connection between the air outlet pipe 20 and the drying drum 7.
