Fresh truffle processing - cleaning, grading, washing, drying and warehousing

The processing is done in our factory in which there are 30 workers including a QA group of 5 workers.

• Cleaning

Use truffle brushes to clean the dirt, mud, foreign materials off the truffle. Dispose of the truffles with superficial deteriorations and appearance defects.

• Grading

Grading is based on the size. Since the round shape of the truffle is irregular, the callipers are used to measure the longest diameter of every truffle.

• Washing

Due to the stricter customs regulations on the import agricultural products, the truffles should be washed.

Our truffles are washed with drinking water and will be finished within 15 minutes. Few other suppliers wash the truffle with drinking water.

• Drying

A blade-type blower is used to dry the truffles. It's the best drying equipment for the truffles after many years of trials and errors.

NOTE: It's worth mentioning that the loss rate is around 15% after the above four processes are completed. We've seen some suppliers offer the fresh truffle at very low price (around USD 12$) - it's almost certain that the truffles offered are not washed.

• Warehousing

After they are dried, the truffles will put into our fridge room (2-5 centigrade). Again, few other suppliers have their own fridge room.
