Ho Chi Minh City, 19𝑡ℎ May 2024 NGUYEN PHUOC VINH DANG NGOC TRI iii ABSTRACT Salt is an abundant product in coastal area of Vietnam, specially Can Gio district.
Although produced in abundant quantities, most still have a large amount left over from exploitation during production and processing. Thus, creating added value from excess waste products for goals such as: saving and optimizing the value of salt is an extremely necessary. The topic of thesis to research and design herbal foot bath salt production line, it will contribute to creating a new produce for excess salt during production and harvesting in Can Gio district, by taking advantages of available products, maximizing production efficiency, also increasing income for people. Through the research for this project, the production line of fine salt granules has been implemented at Can Gio district by Bach Khoa Research Center for Manufacturing Engineering (BK – RECME).
With the actual situation implemented as above, this project also provides additional research for herbal foot bath salt production line for above purposes. From research on the processing method to produce herbal foot bath salt, the principle diagram of each machine in production line is suggested and design and linked together into a complete system.
