The UVTREAT Machine is designed that is capable to treat the fresh tropical juices such as pineapple juice to inactivation of the bacteria at least 5 log10 reduction as required by the Foods and Drugs Administration (FDA). Dean vortex flow concept was adapted in this machine to increase the mixing effect as well as exposure of the microorganism to UV, thus, increase the lethality rate of microorganism. The machine is simple, feasible and a cost saving piece of equipment. It consists of an inlet, UV reactor and outlet. The UV reactor consists of 6 UV lamps in which five of the units are arranged in a circular pattern to minimize the size of the process system yet ease to handle and maintenance. A lamp in the centre of the five lamps that arrange in the circular pattern to boost the effectiveness of the processing system to give extra UV-C wavelength. The UV lamps able to switch on/off individually by using the control panel. Juice is pumped in by hydraulic pump and it is treated at the UV reactor (254 nm) prior packaging at the outlet. The production rate of this machine is depending on the characteristic of the juice and the number of lamp uses.
