Abstract [en]

With the aim of designing an infrasound-integrated technology which can enhance the

algae drying performance, this thesis provided the theoretical possibility of using

infrasound as an algae dehydration technology. To test the relation between algae drying

speed and other three parameters namely sound frequency, sound pressure and sample

mass, four major experimental groups including initial experiments and core

experiments with fifteen sub-experimental groups are designed. Results of the

experiments shows expected accordance with the theoretical inferences of infrasound

being an algae drying technology. Experiment steps and specifications are presented as

the research methodology. A real system with the drying capacity of 2 ton fresh algae

per day are designed based on the experimental calculations and results. Several

revisions including air circulation and infrasound resonance are made when scaling up

the research from experimental level up to industrial level. Other specifications of the

real system design follow the experiment results with regard of the research consistency.

Freeze drying technology is selected for the comparative cost analysis including

manufacturing costs and energy consumptions. Results shows infrasound-integrated

technology has a relatively low energy consumption whereas it costs more

manufacturing costs than freeze drying technology.

Research assumptions, limitations and recommendations for this research are described

in this article. From the author’s perspective, this paper can be used as an initiation and

instruction for larger scale researches in regard of infrasound-integrated algae

dehydration/drying.
