Study on the production process of kapok dry flower
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 12
Abstract
"In order to enrich the varieties of dried flowers on the market and meet people's needs for dried flowers, this article explored the production process of dried kapok flowers. The flowers were pretreated by Ethanol and 10% citric acid mixed solution to keep the colour first. Then they should be embedded in silica gel powder with a diameter of 0.5-1 mm. The experiment on kapok drying was conducted in two different drying machine, a thermostat and a modified microwave oven. From the experiment, we came to several conclusions. The pretreatment of kapok with the color-preserving agent and embedding agent could improve the appearance of dried flowers. Kapok was not suitable for drying with a hot air oven for the reason that being dried by the constant-temperature hot-air for a long drying time would lead to the uneven color and yellowing of the finished flower. By contrast, microwave drying could bring better overall quality and shorter drying cycle. It was a more suitable drying process to use two kinds of microwave combination drying schemes, such as continue heated with 800 W heating for 5 minutes then 200 W for 2 minutes, or continue heated with 400 W for 1 minute after 800 W heating for 5 minutes."
