Description

Technical Field

[0001] The utility model relates to the technical field of processing and drying, in particular to a wolfberry processing and drying device. Background Art

[0002] Goji berries, also known as wolfberries and red earrings, are the mature seeds of the Lycium barbarum shrub, a member of the Solanaceae family. They contain over 80% water. Fresh goji berries are difficult to store due to their thin, juicy skin. This, combined with the structural characteristics of the fruit's peel, makes them vulnerable to compression and prone to mold and rot. Large quantities should not be stored, making them difficult to use and transport. Therefore, freshly harvested goji berries must be dehydrated.

[0003] However, during the processing and drying process, wolfberries will release water and a small amount of sugar will be released on the surface, making it easy for the wolfberries to stick to the drying rack, which will cause the wolfberries to dry locally and quickly, easily become over-dried, and lose their nutritional value. At the same time, the storage time is reduced, and the stuck wolfberries are inconvenient for subsequent packaging and use. This requires staff to turn the wolfberries over and dry them frequently, which greatly increases manpower and physical exertion. At the same time, wolfberries are of different sizes and are easy to be dried in the same way, but some are dried and some are not yet dry. Mold and other conditions are likely to occur during transportation, which will reduce the quality of the wolfberries and even cause safety problems. Utility Model Content

The first conveyor belt 403 is provided on the side surface of the first conveyor wheel 402. The electric heating tube 401 is connected to an external power source and then activated to generate heat, which roasts the wolfberries, removes some of their moisture, and prolongs their storage time. The first conveyor belt 403 cooperates with the first conveyor wheel 402 to transport the wolfberries for roasting.

[0027] Two second conveyor wheels 404 are provided, horizontally and relatively rotatably connected to the inner wall of oven 1. A second conveyor belt 405 is provided on the side surface of second conveyor wheel 404. Multiple scrapers 406 are provided, evenly and horizontally fixedly connected to the inner wall of oven 1. Scrapers 406 are closely attached to first and second conveyor belts 403 and 405.

Gear No. 1 407 is meshed with gear No. 2 408, and motor No. 2 411 is connected to an external power source and then started to control the rotation of rotating shaft 409. Rotating shaft 409 rotates coaxially with gear No. 1 407, which can drive gear No. 1 407 to rotate, and then drive gear No. 2 408 to rotate in the opposite direction. The gears rotate coaxially with the corresponding conveyor wheels, and finally drive conveyor belt No. 1 403 and conveyor belt No. 2 405 inside oven 1 to transport in opposite directions. Conveyor belt No. 1 403 and conveyor belt No. 2 405 cooperate with each other to control the transportation of wolfberries inside oven 1, which is convenient for drying.

[0029] A plurality of pillars 7 are fixedly connected to the lower surface of the oven 1. Two rectangular openings 10 are provided on the lower surface of the oven 1. A first collecting box 8 is movably connected to the lower surface of the left rectangular opening 10, and a second collecting box 9 is movably connected to the lower surface of the right rectangular opening 10. On the lower surface of conveyor belt No. 2 405, a scraper 406 is provided in the middle position of the two rectangular openings 10. When the wolfberries reach the end of conveyor belt No. 2 405, the dried wolfberries will fall normally and enter the collecting box No. 1 8. However, a few larger wolfberries may not be dried and there is still moisture on the surface, causing them to stick to the surface of conveyor belt No. 2 405. When they reach the end of conveyor belt No. 2 405, they will not fall normally and will stick. When they are stuck to the surface of conveyor belt No. 2 405 and reach the scraper 406 on the lower surface of conveyor belt No. 2 405, they will be scraped off and fall into the inside of collecting box No. 2 9, indicating that the wolfberries inside collecting box No. 2 9 are not completely dried. The wolfberries inside collecting box No. 2 9 can be put back into the hopper 307 for secondary drying.

[0030] Working principle: First start the electric heating tube 401 to make the temperature inside the oven 1 reach the predetermined temperature, then put the cleaned wolfberries into the hopper 307, and the wolfberries are fed into the feeding cylinder 306, then start the No. 1 motor 305, control the rotation of the shaft 303 to drive the spiral plate 304 on the surface to rotate, and the wolfberries fed from the feeding cylinder 306 can be controlled to pass through the fixed pipe 301 into the oven 1 for baking in an orderly manner. At the same time, the air inlet 5 is connected to an external hair dryer, which can introduce airflow to accelerate the air flow inside the oven 1, accelerate the drying, and evenly distribute the internal air. The internal temperature is adjusted to prevent local overheating, and then the second motor 411 is started to control the rotation of the rotating shaft 409. The rotating shaft 409 rotates coaxially with the first gear 407, which can drive the first gear 407 to rotate. The first gear 407 is engaged with the second gear 408, and then drives the second gear 408 to rotate in the opposite direction. The gears rotate coaxially with the corresponding conveyor wheels, and finally drive the first conveyor belt 403 and the second conveyor belt 405 inside the oven 1 to transport in opposite directions. The first conveyor belt 403 and the second conveyor belt 405 cooperate with each other to The wolfberries are transported in the oven 1 to facilitate drying. A scraper 406 is provided on the lower surface of the No. 2 conveyor belt 405, located between the two rectangular openings 10. When the wolfberries reach the end of the No. 2 conveyor belt 405, the dried wolfberries will fall normally and enter the No. 1 collection box 8. However, a small number of wolfberries with larger body and higher water content may not be dried and still have moisture on their surface, causing them to stick to the surface of the No. 2 conveyor belt 405. When they reach the end of the No. 2 conveyor belt 405, they will not fall normally but will stick. When the scraper 406 connected to the surface of the No. 2 conveyor belt 405 reaches the lower surface of the No. 2 conveyor belt 405, it will be scraped off and fall into the No. 2 collecting box 9, indicating that the wolfberries inside the No. 2 collecting box 9 are not completely dried. The wolfberries inside the No. 2 collecting box 9 can be put back into the hopper 307 for secondary drying. The remaining scrapers 406 are used to turn over the wolfberries inside the oven 1, so that the wolfberries stuck on the conveyor belt can be separated from the conveyor belt, avoiding uneven heating, resulting in more moisture, easy to mold or over-drying and loss of nutritional value.

[0031] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
