Fully Automatic Raisin Washing And Drying Processing Line

Full Automatic Raisin Washing and drying processing line

Working Process:

Process 1 (for racemation raisin): 

Elevator conveyor ➜ Stem remover+winnower machine➜ Elevator conveyor ➜ Color sorting machine ➜ Grading machine ➜ Elevator conveyor ➜Picking machine ➜ Drum washing machine (used for dirty raisin) ➜Bubble washing machine ➜Dehydrator ➜Discharging conveyor ➜ Oiling machine➜Vibrating and flattening Screener ➜ Lifting Feeder ➜ Multi-layer drying machine ➜ Air cooling machine.

Process 2 (for block raisin): 

Raisin separator+Vibrating screener+ Elevator conveyor ➜ Bubble washing➜ Dehydrator ➜ Discharging Elevator ➜ Vibrating and flattening Screener ➜ Lifting Feeder ➜ Multi-layer drying machine ➜ Air cooling machine.

Equipment description:

1) Raisin separator+Vibrating screener+ Elevator conveyor
Working principles: After separation by the separator, the raisins fall on the vibrating screen. After screening, the separated raisins fall on the conveyor belt and are lifted into the washer. The partial raisins which are not fully separated will be discharged through the front side of vibrating screener and be put into the separator manually for separation again.The vibrating screener is directly installed on the support of conveyor belt. The separator is provided with the rubber protection.

2) Bubble washing machine:

The machine washing speed is controlled by the inverter motor and the washing speed can be freely adjusted. The washer adopts bubble rolling and spraying technologies. The high-pressure water flow will make the material roll to remove the impurities on the surface of products. The floating objects can overflow through the overflow launder and the sediments can discharge through the drain hole for cleaning purpose. The bubble washing line can adopt the motor to lift the whole liner of equipment for facilitating customers removing the dirt at the bottom of equipment and maintenance while use it. This is the proprietary technology of our company.

3) Wringing Dehydrator:

Ensure the smooth operation of equipment and achieve the wringing effect. The material discharging elevator will lift the wringged raisins into the vibrating screener.

4) Discharging elevator:

Lifting the wringed raisins into the vibrating oil sprinkling machine

5) Vibrating and flattening screener:

Spreading out the wringed raisins and convey them into the hot air drying machine. The oil injection process may be implemented during this period.

6) Lifting feeder:

After spreading out the raisins by vibration, lift them through the lifting feeder into the hot air drying machine for drying.

7) Multi-layer drying machine:

Lift the cleaned raisins through the lifting feeder on the conveyor belt and the conveyor belt operates circularly in the hot air drying machine. The heating group is placed at one side and circulates the hot air in the drying machine through the axial flow fan with high temperature resistance which will keep the quantity of heat stable. The hot air flows through the raisins on the convey belt from the front to the back and makes them dry quickly.

8) Air cooling machine: Cool the dried raisins by wind and box them.
