Testing scope of steam ovens

 

Consumer Council, together with the Electrical and Mechanical Services Department, tested 8 steam ovens in the market, ranging from $1988 to $6300. The tests were scored based on performance, environmental protection, safety, surface temperature control, ease of use, and degree of compliance. In view of the fact that the steaming oven is a cooking utensil, the Council has specially added a cooking test to compare the colour and taste of the steamed oven samples.

Cooking speed of steam oven

 

First of all, we can see the results of the steaming and baking test of the steam oven. The Concil tested the steam oven's cooking speed by steaming the frozen green beans to examine whether 5 positions of the steamed oven could rapidly reach. The test result shows that different types of ovens may vary considerably, ranging from 28 to 63 minutes. In addition, for the speed of cooking, there are 4 steam ovens in the test to reach the preset preheat temperature with only 8.5 minutes. Only individual styles have not yet reached the mark for 30 minutes in the test.

 

Cooking effect of steam oven

 

The color and taste of food are the most important for the cooking utensils. The researchers found the uneven temperature distribution of 1 oven sample by cooking cupcakes, green peas, broccoli and baked seafood rice, and there is great difference for the color of cupcakes. The cooked broccoli with all oven samples were slightly yellow. All oven samples can produce delicious baked seafood rice. Consumer Council recommends that if you have higher requirements for food, you should carefully research the temperature of the oven and the time it takes to cook.

 

Capacity of steam oven

 

For the degree of conformity of the steaming oven, the Council found that the capacity of the steam oven listed by most manufacturers was somewhat different from the reality. Except that the Whirlpool of CS2320 is exactly the same as the actual capacity (both are 32 liters), the actual capacity of other steam ovens is less than the claimed. There are two types of ovens, with actual capacity less than over 25% of the claimed capacity. In accordance with Council's interpretation, the producer may calculate the upper and lower positions of heat generating line in the steam oven into the capacity. Since such position cannot be placed with food, it should not be calculated as the "usable space". Consumers should pay attention to whether the capacity of the selected stoves is adequate for daily cooking.

As for the environmental protection performance, since the steam oven requires high power and is also used frequently, therefore, if customers choose products with high energy efficiency, they can not only protect the environment, but also save the electricity. In addition to the gas cooking stove, the Hong Kong people are now cooking with the electromagnetic ovens, so the Consumer Council compares the power consumption of the steam oven and the electromagnetic oven respectively. The test result shows that the steam oven can use less electricity than the electromagnetic oven. The steam oven's average electricity consumption is 0.26kWh, and the electromagnetic oven is used 0.543kWh that the electricity of the steam oven is nearly the half. If calculated by HKD$1.2 per kilowatt hour, an average of nearly $124 is saved by using steam oven a year. It can be seen that the steam oven's energy efficiency is good that families could use steam oven instead of electromagnetic furnace to save the cost.

 

After comparing various scores, it is found that although the type and price of the steam oven are different, there are 3 types of steam ovens which are Whirlpool CS2320, Panasonic NU-SC100W and Gemini GS017G respectively with almost the same effect performance. Especially CS2320 is the best among them.

 

Tips for using steam oven (by Consumer Council)

 

Consumer Council also offers tips for the use of steam ovens:

  • Since the power of the steam oven is higher, a single outlet shall be used independently.
  • Ventilation space should be provided on the back and top of the machine. Do not place it close to the combustible articles such as curtains, plastic or paper.
  • Pay attention to the heat generating wire in the baking furnace and the high temperature on the surface. Do not use any cleaning articles that are abrasive to clean the surface of the glass on the furnace door so as to prevent the glass from breaking.
  • To avoid touching the stove while cooking. Do not allow the children to use or touch it alone.
  • After use, the removable grill or shower tray should be washed, and the heat generating pipe and internal wall could be wiped with soft cloth. The steel brush is prohibited to be use to prevent from scratching the surface, resulting in rust.

 

Standalone steam oven VS Built-in steam oven

 

Consumer Council tested the sitting steam oven that the model has the advantage of convenient movement but has a smaller capacity. Among that, the maximum capacity is 32 liters Whirlpool CS2320. If you want a steam oven with larger capacity, you can consider the embedded steam oven. In addition to the general capacity of over 50 to 70 liters, its embedded design can also make the kitchen more neat and unified, and the wires are not exposed. At present, many types of steam ovens have the functions of oven, microwave oven and steaming furnace.
