Description

Circulation boiling type domestic full-automatic soya bean milk machine

Technical field

The utility model relates to beverage maker, specifically a kind of circulation boiling type domestic full-automatic soya bean milk machine.

Background technology

Existing domestic full-automatic soya bean milk machine, soya-bean milk heats when boiling at heating container, owing to constantly produce vapours in the heating process, produce increasing bubble when boiling, the rapid thermal expansion of soya-bean milk volume, therefore all be the normal pressure heating of taking container and atmosphere to connect, the slurry that overflows particularly takes place in order to prevent to boil, cut off heating power supply in the time of must utilizing the anti-flow electrode action, temporarily stop to add hot soya-bean milk and avoid the slurry that overflows, energising heating again heated, stops could to make ripe soya-bean milk several times so repeatedly after the liquid level of waiting to lower the temperature descended.The heating soybean milk mode must be just to have reached boiling point in heating soybean milk just to have to stop heating under this normal pressure, causes that the heating soybean milk temperature is limited within 100 ℃ when adding hot soya-bean milk, and the soya-bean milk quality and the taste of preparation are affected.

Summary of the invention

The purpose of this utility model is exactly at the above-mentioned defective of prior art, a kind of circulation boiling type domestic full-automatic soya bean milk machine structure is disclosed, can keep the long period to continue heating boiling soya-bean milk being higher than to be above the boiling point under the atmospheric minute-pressure, the soya-bean milk aromatic taste of preparation meets safe standard for drinking requirement.

The technical scheme that realizes the utility model purpose is: a kind of circulation boiling type domestic full-automatic soya bean milk machine structure, include motor, cutter shaft, blade, filter bowl, temperature measuring equipment, heater, attemperating unit and heating soybean milk device, circuit board, power supply and circuit controller spare, motor is an overhead, upper coupling fixing on the motor shaft is connected with the following shaft coupling that the cutter shaft upper end is fixed, heater is an electric hot tray, the heating soybean milk device places on the heating plate, the temperature measuring equipment thermal detector contacts with heating soybean milk device outer wall, the heating soybean milk device has outer bucket, inner core and bung, the inner core upper end is installed on the bung inner face, the bung spiral-lock is the bucket upper end outside, the inner core sidewall is provided with intercommunicating pore, cutter shaft passes bung and stretches into inner core, cutter shaft front end fixed installation blade, and the filter bowl upper end of outer cover blade is installed on the bung inner face

The method that background technology adds hot soya-bean milk is that normal pressure adds hot soya-bean milk in container, no matter be to add hot soya-bean milk with heater from container bottom or from internal tank, heat all is from container bottom centre or the middle conduction of free convection to the periphery of soya-bean milk liquid, in general apart from thermal source nearby the soya-bean milk liquid temp be higher than at a distance, near the soya-bean milk liquid of container side wall since heat to container external radiation conduction and temperature is relatively low, and the soya-bean milk liquid temp at middle part is higher.The heating soybean milk device of the disclosed circulation boiling type of the utility model domestic full-automatic soya bean milk machine is at the characteristics and the causality of background technology, soya-bean milk is placed when heating in the lidded container that is interconnected inside and outside two, because the soya-bean milk temperature is higher than soya-bean milk temperature in the outer bucket in the inner core, it is fast and many to produce vapours, the thermal expansion degree is also big, soya-bean milk liquid thermal expansion liquid level is raised higher than outer bucket in the inner core, it is not enclosed construction that inner core is installed on the bung, the heat steam that inner core top constantly produces is owing to be subjected to stopping of bung and can accumulate to form and be higher than atmospheric pressure 10-20 kPa minute-pressure, the heating soybean milk temperature can be above 100 ℃ when boiling, when high warm milk liquid liquid level reaches the intercommunicating pore that is provided with on the inner core sidewall earlier in the inner core, high warm milk liquid is under the siphon effect effect of thermal expansion and the generation of inside and outside liquid level difference, will flow into outer barrel from intercommunicating pore, the high warm milk liquid that enters outer bucket shrinks except that reduce temperature relatively owing to the heat radiation conduction of outer barrel wall, outside the froth breaking, also outwards flow and continue heating from the inner core lower end inflow inner core that is communicated with and rise in the bucket below, experiment detects and shows that soya-bean milk can be heated to 105 ℃ the pot that overflows can not take place yet, so soya-bean milk liquid just the inner core of heater with outside barrel between under minute-pressure in order circulate different of formation with background technology, being implemented in is above the boiling point down keeps continuing the purpose that soya-bean milk is boiled in heating, particularly under the minute-pressure effect of high temperature and the formation of inner core top, producing with the outstanding different effect of prior art is that soya-bean milk can obtain high temperature emulsification more fully, the soya-bean milk sweet-smelling that makes is agreeable to the taste, harmful components in the raw soya-bean milk are decomposition and inversion fully, reaches safe standard for drinking.
