On March 1, 2024, the 24T/D rice bran wax refining project designed and manufactured by Huatai Group was sent to Jiangsu.

Our country is the world rice producing country, rice bran is the by-product of rice processing. In the process of making oil from rice bran, the rice bran wax will be separated with the oil and fat to get the by-product called wax paste, and the wax paste will be refined and purified to get bran wax. Rice bran wax is a mixture of esters composed of high-level fatty acid and high-level monohydric alcohol, it is a by-product obtained when refining edible rice bran oil, and it is also an important raw material of oil chemical industry. Compared with the synthetic wax, it has the advantage of non-toxicity and forms the status quo with the Brazilian carnauba wax.

Rice bran wax is a light yellow block with a slight smell of rice bran. It has a melting point of 60-85 ℃ and can dissolve with various natural waxes. It is insoluble in water, difficult to dissolve in ethanol, and hot soluble in organic solvents such as xylene, trichloroethylene, and benzene. The main ingredient is bee flower ester of dodecanoic acid. Can be directly added to food for foaming, moisture resistance, and polishing. It can also be used as a stripping agent, coating agent, etc. in food processing. Obtained by separating and refining rice bran oil.

1. Purification of wax: Rice bran wax is a wax separated from the refining process of rice bran oil, which contains a certain amount of rice bran oil. The purpose of purification is to remove the rice bran oil in the wax and obtain pure rice bran wax. During the purification process, attention needs to be paid to controlling factors such as temperature, stirring speed, and separation time to ensure the purification effect.
