[0002] Persimmon is a tree plant of the genus Diospyros in the family Ebenaceae. Persimmon likes warm climate, plenty of sunlight and deep, fertile, moist, well-drained soil, moderate soil, is relatively cold-resistant, relatively tolerant of barrenness, has strong drought resistance, but is not tolerant of saline-alkali soil.

[0003] After picking persimmons, they are usually not eaten or processed immediately, but are first ripened and softened to facilitate nutritional conversion and improve taste. The current ripening method is to spray ripening agents on the surface of the persimmons. Therefore, a spraying device is usually used to assist in spraying the ripening agent.

[0004] However, the existing spraying device has the problem of uneven spraying when in use. Usually, when performing large-scale spraying, most of the persimmons are transported by a conveyor belt, and then the ripening agent is sprayed on the surface of the persimmons, but the bottom of the persimmons cannot be effectively sprayed, so the bottom of the persimmons is usually difficult to ripen.

10. A processing method for the persimmon de-astringency ripening agent spraying device according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: First, put the persimmons that need to be de-astringent and ripen into the lower hopper, so that the persimmons flow out of the lower hopper and slide onto the spiral plate mountain, so that the persimmons roll and spiral down along the spiral plate; S2: Start the delivery pump to deliver the ripening agent in the ripening agent storage chamber to the main pipe, and then deliver it to the branch pipe through the main pipe. Then the branch pipe is split and delivered to each spray branch pipe, and finally sprayed from the atomizing nozzle on the spray branch pipe, so that the persimmons spirally descending along the spiral plate can be evenly sprayed with the ripening agent; S3: After spraying, the excess ripening agent falls to the bottom of the spray box through the through holes on the spiral plate, and then passes through the filter screen to filter the impurities in the ripening agent, so that the liquid passes through the filter screen and enters the recovery chamber for centralized collection; S4: During the process of rolling and spraying the ripening agent on persimmons, the operator can observe the flow state of the persimmons on the spiral plate through the transparent observation window and the transparent cover. When the persimmons stay on the spiral plate and cause blockage, the vibration support assembly can be started to make the vibration motor vibrate the base, and the vibration force is transmitted to the spiral plate in the spray box. During the vibration, the mounting seat can slide along the T-shaped seat under the effect of the guide groove, and squeeze the spring to generate elastic potential energy, so that the persimmons continue to flow along the spiral plate under the effect of vibration to prevent blockage, and finally flow out from the discharge guide groove to complete the de-astringency and ripening work.
