At present, most of the intelligent soya-bean milk machine is control by microcomputer. As long as the soya-bean milk machine start work, the process of grinding, leaching and cooking is fully automated. A short span of ten minutes the soya-bean milk would been done. Not only hygienic and reliable, but also quickly and conveniently.
This article discusses the system of the intelligent soya-bean milk machine including the single-chip of PIC16C54, Sensor, Functional circuit, Boiling detection circuit, Grinding circuit, Heating control circuit and Alarm circuit. The course is that: At first, add some soy bean in the blender's filter, poured an appropriate amount of water into the blender and installed blender. When connected to power supply, the buzzer sounded once, tips have been connected to power, the LED light up, tips the Soya-bean milk machine in the standby. Press the button of START to start heating. When the temperature reached around 75℃ stop heating, Stirring motor operation will be crushed soybeans and the soya-bean milk is filtered, then the motor stopped and started heating until boiling, and stop heating, issued a warning sound prompted milk have been done. If a long time not to drink and become cool, press the button of HEAT to start heating again until to boiling and issued a warning sound. If dry, turn off the heater and motor, press any button not to respond, and issued a alarm sound until adding enough water to continue to use it.
The soya-bean milk production processes including grinding, leaching and cooking. The three processes worked closely, so that milk tastes better. Such as pre-heating before grinding can not only improve efficiency and shorten the cooking time, prevent the cooking time is too long to cause the paste pot.
