EXPERIMENTAL STUDY TO EVALUATE THE EFFECTS OF ULTRASONIC WAVES IN A GANODERMA MUSHROOM DRYING DEVICE USING THE HEAT PUMP COMBINED WITH ULTRASONIC WAVES

Abstract

Ganoderma lucidum is known for its wide range of health beneöts, and has been used in
traditional Asian herbal medicine for thousands of years. It contains valuable bioactive substances,
including polysaccharides, triterpenoids, peptides, and other antioxidants. The polysaccharide
component is one of the most effective ingredients contained in Ganoderma lucidum, and is highly
valued by medical scientists. This article discusses the inøuence of ultrasonic wave parameters
including power and interruption rate of ultrasonic waves on parameters of the drying process such
as drying time, speciöc electricity cost, color change, loss of Polysaccharides content of Ganoderma
lucidum after drying. Research results show that the power and interruption rate of ultrasonic
waves affects the parameters of the Ganoderma drying process such as drying time, and speciöc
electricity cost, color change, and loss of polysaccharide content.
