Vapor-solid mixer design for cinnamal tea production

Abstract

The utilization of natural products that potentially act as anti-cancer has been widely investigated. Our previous study in 2019 on microencapsulation of several essential oils, including citral with aldehyde moiety and citronellal from lemongrass, and cinnamaldehyde from cinnamon, has proved remarkably successful to prevent cancer risk (chemo-prevention). The study is then extended to produce tea-based products with citral and cinnamaldehyde oil additives as cancer risk prevention drink drinks. The study will aim to optimizing the mixer parameters to overcome the volatility rate of essential oil. The research was designed with the Analysis, Defining, Development, Implementation and Evaluation (ADDIE) model. It was conducted to make sure that all the machine parameters work efficiently. The developed machine is equipped with a heater tank and mixer. The heater tank and mixer capacities are 2.2 L and 4.0 L, respectively. The maximum pressure tank is up to 4.0 bar, and the recommended pressure works are 2.0 bar. The heating temperature maximum is 170 °C, and it will also keep the essential oil stability. The vapor-solid mixed gently at 20 rpm to produce a well-mixed product. Power consumption up to 1500 watts at 220 V (50 Hz). However, the product at the mixing time of 60 seconds with the gas flow 2 bar was perfectly obtained.
