The cleaning tank 2 is installed at the front end of the rack 1. A fruit overflow port 11 is arranged at the end of the cleaning tank 2. A strip-shaped fruit sinking groove 12 is arranged at the bottom of the cleaning tank 2. A partition plate 13 is arranged at the end of the cleaning tank 2. The end of the cleaning tank 2 is divided into a fruit sinking cavity 14 by the partition plate 13. A through hole 15 is arranged at the bottom of the partition plate 13 for the fruit sinking and sand to pass through. A water flushing pipe 16 connected with a water supply system is arranged at the front end of the strip-shaped fruit sinking groove 12. The fruit floating screening drum 3 and the fruit sinking screening drum 4 are both installed at the end of the rack 1. The rack 1 is provided with a fruit floating feeding drum 17 and a fruit sinking feeding drum 18 for guiding the material into the fruit floating screening drum 3 and the fruit sinking screening drum 4 respectively. The fruit floating feeding drum 17 is connected with the fruit overflow port 11. The fruit sinking feeding drum 18 is communicated with the top of the fruit sinking cavity 14. A motor 10 is arranged on the rack 1. The motor 10 is drivingly connected with the fruit floating screening drum 3 and the fruit sinking screening drum 4. The coffee fruit is cleaned and floated by the cleaning tank 2. The overripe fruit (floating fruit) and dry fruit are discharged through the fruit overflow port 11 and screened by the fruit floating screening drum 3. The dry fruit is screened out by the fruit floating screening drum 3. The overripe fruit is collected through the end of the fruit floating screening drum 3. The fruit sinking and sand sink into the strip-shaped fruit sinking groove 12 and enter the fruit sinking cavity 14 through the through hole 15 by the impact of the water flushing pipe 16. The relatively heavy sand is deposited at the bottom of the end of the strip-shaped fruit sinking groove 12. The relatively light fruit sinking is carried to the fruit sinking feeding drum 18 by the impact of the water flow. The small sand is screened out by the fruit sinking screening drum 4. The fruit sinking is collected through the end of the fruit sinking screening drum 4. The high-precision separation of the ripe fruit, unripe fruit, dry fruit and impurities is realized. The quality of the raw material is significantly improved. The structure is compact. The water is collected, treated and reused. The fresh water consumption can be greatly reduced (more than 70% can be saved). The working efficiency is high. The labor intensity is effectively reduced.

[0022] The end of the strip-shaped fruit sinking groove 12 is provided with a sand deposition groove 19 lower than the strip-shaped fruit sinking groove 12.

The large block sand is avoided from mixing into the coffee and damaging the peeling machine.

[0023] The sand deposition tank 19 is provided with a drain pipe 20, and a valve is arranged on the drain pipe 20. After regular cleaning or after finishing processing, the sand and cleaning water are discharged through the drain pipe 20.

[0024] The bottom of the floating fruit screening drum 3 and the sink fruit screening drum 4 is provided with a water outlet collecting hopper 5, and the bottom of the water outlet collecting hopper 5 is provided with a water collecting tank 51. The water outlet collecting hopper 5 is used to collect the water leaked from the floating fruit screening drum 3 and the sink fruit screening drum 4, so as to avoid splashing of sewage and ensure the workshop environment.

[0025] The bottom of the floating fruit screening drum 3 and the sink fruit screening drum 4 is provided with a water outlet collecting hopper 5, and the bottom of the water outlet collecting hopper 5 is provided with a water collecting tank 51.
