The palm plantations are outsourced in different areas, and the maturity of the fresh oil palm fruits is monitored every day and the fallen fruits are cleaned and recycled. Fresh fruit bunches with more than 5 palm fruits that normally fall are the picking targets. After picking, the fresh fruit bunches are transported to the processing factory within 16 hours for grading. 100 fruit bunches are randomly selected from each truck and the proportions of raw fruits, underripe fruits, ripe fruits, overripe fruits, diseased fruits, and empty fruit bunches are checked. The qualified proportions are: raw fruits: 0%; underripe fruits: <1%; ripe fruits: >95%; overripe fruits: <5%; empty fruit bunches: 0%; rotten fruits: 0%; long-stemmed fruits. : <1%; small fruit bunches less than 3kg: 0%; diseased fruits: 0%; dura fruits: 0%.

The picked and graded fresh fruit bunches are transported, cleaned and entered into the FFB sterilization process using the fruit unloading platform of the present invention. The sterilization conditions are that the steam pressure is 0.4MPa, the temperature is 120°C, and the pressure holding time is 45 minutes. At the same time, microwave treatment is started, using a microwave heater with a power of 200kW, and the microwave treatment time is 25 minutes.

The fruit unloading platform includes a fruit platform 1, a slope 2, a conveying device 3 and a gate structure 4. The fruit platform 1 is laid on the ground, the slope 2 is connected to the fruit platform 1 and laid on one side of the pit, and the conveying device 3 is fixed. On the bottom of the pit, the gate mechanism 4 is arranged in the pit, and the slope 2 and the conveyor device 3 are located on different sides of the gate mechanism 4 respectively. The conveying device is shown in Figures 2 and 3, which includes: a base plate 3a, a chain 3b, at least two sprockets 3c and a plurality of conveying scrapers 3d; wherein the plurality of conveying scrapers 3d are detachably It is arranged on the chain 3b, and the chain 3b performs a rotary motion driven by the at least two sprockets 3c. The bottom plate 3a is arranged below the chain 3b. When the fruit body slides down from the slope 2 to the bottom plate 3a, it moves along the bottom plate 3a driven by the plurality of conveying scrapers 3d. As shown in Figure 4, the gate mechanism 4 includes: at least one hydraulic lift door 4a arranged side by side. When the at least one hydraulic lift door 4a is opened, the fruit body slides down from the slope 2 to the gate. in conveying device 3.

The obtained fresh fruit bunches are threshed with a drum thresher. The fallen palm fruits are collected by the conveyor under the thresher and transferred to the digestion tank for digestion operation. The temperature of the digestion tank is 90°C, the rotation speed is 25 rpm, and the digestion time is 10 minutes.

The obtained palm fruit is pressed in a screw press, and the crude oil obtained is filtered through a vibrating screen with a 20-mesh filter. The crude oil is separated from fibers, palm shells, impurities, etc., and the separated crude oil is precipitated. , and centrifuge the sludge to recover the oil, and finally separate the water and light dirt in the oil.

The obtained palm oil was dried with a vacuum dryer at a drying temperature of 70°C.

The palm oil obtained was stored in nitrogen-filled storage tanks.

The industrial water and boiler water used in the above process steps are water produced by RO reverse osmosis water treatment equipment. Huatai company is leading palm oil machine manufacture in China, any need please email to info01@cnoilmachine.com
