<p>Equipment and process for producing biodiesel cracking fat with the help of ultrasound and hydrogen peroxide, where preliminary filtered fat is placed at least into one tank (1) and its temperature is raised with the help of heat exchanger (2) up to 35 - 50 C° to reduce the viscosity. Fat is circulated in the tank (1) through the ultrasonic device (3), which is mixing fat in micro scale. "When the appropriate viscosity is reached, the fat will be transported irtfo the next ultrasonic device (4) where the cracking is continued using ultrasound and hydrogen peroxide. The frequency of ultrasonic sound in all devices is 15 - 55 kHz. After that the fat is transported into at least one tank (5), where aqueous and fat phases will be separated by settling. Temperature of the fat will be kept still at 35 - 50 C° using heat exchanger (6) and to stimulate the process the grease will be circulated in the tank (5) through the ultrasonic device (7). Produced biodiesel will be filtered. Resulting water with its ingredients (possibly table salt for example) will be handled in an appropriate way.</p> |
