摘 要

目前流行的智能豆?jié){機大都采用微電腦控制，只要啟動豆?jié){機，磨漿、濾漿、煮漿完全自動化，短短十幾分鐘就自動做好豆?jié){，既衛(wèi)生可靠，又快捷方便。
本文介紹的智能豆?jié){機系統(tǒng)由 PIC16C54單片機、傳感器、功能電路、沸騰檢測電路、磨漿電路、加熱控制電路和報警電路等組成，豆?jié){生產(chǎn)完全自動化。其工作過程是：先將黃豆放入豆?jié){機的攪拌器濾網(wǎng)內(nèi)，攪拌壺內(nèi)倒入適量的水，裝好攪拌機。接上電源，蜂鳴器長鳴一聲，提示已經(jīng)接通電源，指示燈LED亮起，處于待命狀態(tài)。按下全自動啟動鍵START開始加熱，當溫度達到75℃左右時，停止加熱；攪拌馬達運轉，將黃豆粉碎，豆?jié){過濾，而后馬達停轉，又開始加熱，直到豆?jié){沸騰煮熟，停止加熱，發(fā)出報警聲，提示豆?jié){已做好。若豆?jié){較長時間沒喝而變涼，按下再加熱鍵HEAT，加熱至沸騰，停止加熱，發(fā)出報警聲。若缺水，則關閉加熱器和馬達，按任意鍵不響應，并發(fā)出急促的報警聲，直到關閉電源，加水后才能繼續(xù)使用。
豆?jié){生產(chǎn)的工序包括磨漿、濾漿、煮漿，而三個工序又密切配合，使生產(chǎn)的豆?jié){味道更好。如磨漿前進行預加熱，既可以提高工作效率，又縮短煮漿的時間，防止磨漿后煮漿時間過長所易造成的糊鍋現(xiàn)象。

ABSTRACT

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.
