Effect of Temperature on Drying Performance of Stingless Bee Pot-Pollen Using Swirling Fluidized Bed Dryer

Stingless bees or also called “Kelulut” in Malaysia are commonly known for its honey. Besides honey, pollen from flowering plants is also collected by worker bees, mixed with nectar and bee enzymes before storage cerumen pots in their hives. This bee product is called bee bread or pot. Pot-pollen is...
