SoyaPower Soy Milk Maker

This soy milk maker is a newer version of the SoyaJoy. The main differences with the SoyaJoy are the greater size of the filter cup and plastic cover over the stainless steel container. The plastic cover reduce noice and energy consumption during operation. The soy milk making process is controlled by a microcomputer. The filter consists of a large stainless steel mesh filter, which is easily screwed on the head of the machine (it screws on anti-clockwise, direction LOCK and OPEN are mentioned on the cup). The soybeans can be put in the filter cup beforehand or through a special feeding window in the head of the soy milk maker. The machine head can stand on its own, even upside down. The machine head can even be firmly attached to the container with two latches. The grinding knife consists of 4 blades (all other soy milk makers have only 2 blades, except for the QT400). The heating is done by a large heater element, which is attached to the head. The SoyaPower has three buttons: one for milling (MOTOR), one for heating only (HEATER) and for making automatically soy milk (START). We only tested this soy milk maker for producing soy milk, but the SoyaPower can also make rice milk, almond milk and more.
The SoyaPower is delivered with a special dripping cup to hold the head with attached filter cup. This allows the filter cup to drain, so you can recover some more soymilk. Included with the SoyaPower are also a measuring cup (holding 100 g dry soybeans), a cleaning brush, a scrub sponge and a special cleaning powder.

Operating instructions

These are the operating instructions as described by the manufacturer of the SoyaPower (these instructions are similar to those of the SoyaJoy).

• Measure 80 to 100 grams of dry soybeans, rinse and soak between 6 to 16 hours (8 to 10 hours is best). Rinse the soaked soybeans again with clean water before putting them into the machine.
• Add drinking water into the cylinder to between the two water level marks. The manual does not mention the quantity of water corresponding to these lines but we measured 1300 and 1500 ml. There is no need to use warm or pre-heated water for the SoyaPower.
• Feed the soaked soybeans through the feeding window. You can also put the soaked soybeans directly into the filter cup before attaching it to the head of the soy milk maker.
• Connect the SoyaPower to the power supply and push the START button. With a beep, the soy milk maker will start to work through a programmed sequence. First, the machine will heat the water to about 80°C and then start grinding the soybeans. The machine will beep in about 15 minutes to signal that the soy milk is done and ready for use.
• Remove the powder cord from the SoyaPower, lift the head off the cylinder and poor all soy milk in a different container.
• Rinse the heating element and filter cup with tap water to cool it down before taking of the filter cup for cleaning. Clean the filter cup immediately with the brush after each batch. Clean the blade, electrode, heater element and feeding window.

Test results

For this test, 112 g dry soybeans were used in 1500 ml cold water.

• Mixing temperature. The temperature at which the first milling will start should be high enough to avoid beany taste. We tested by using cold (15°C) and warm (35°C) water. In both cases, the milling started at a temperature around 80°C. This means that a thermostat correctly controls the start of the milling.
• Yield of soy milk.
  The strength of the soy milk is 4.0% dissolved solids and total quantity is 1388 ml. The soy milk contains about 9% suspended matter, mainly fine okara. Total yield calculated from these figures is 51,2%.
• Taste.
  The taste of the milk produced by the SoyaPower is good and comparable to commercial soymilk without additives (such as salt and sugar).
• Cleaning
  It is easy to clean this soy milk maker. Most of the heating takes place before grinding process so there is nearly no build up of dirt on the heater element. You can actually wipe it clean with a damp paper towel. It is important to flush the filter cup immediately after use and before allowing it to cool. The parts of the head that get dirty can be flushed under streaming water.

Advantages

• Machine head can be placed upright on any flat surface.
• Improved safety.
• Low noise level during milling.
• Feeding window makes loading of soybeans easy.
• Easy to dismantle and clean.
• Large filter cup makes it possible to add more soybeans to make stronger soy milk, or to add cereals such as oats to improve taste and creaminess.
• Large quantity of soymilk per batch.
