size

In fact, the size of the oven capacity is not only the difference between how much food is loaded, but also the secret of your lifestyle.

9-30 liters

Mainly depends on the face value, most of the time is used to decorate the kitchen.

▲ 9L oven only

This kind of oven is suitable for 1-2 people. Small size, simple function, and can also be used as an ornament when not in use. Can be placed directly on the cabinet, close to the power supply, can be moved at any time.

▲ Only suitable for cooking small dishes.

Because there are many size restrictions, you can cook some simple small and flat dishes, such as toast, to solve the problem of breakfast or dessert in the afternoon. When baking high-tech West Point, the top of the cake may be burnt because it is too close to the heating pipe, which makes it more difficult for friends to get together and bake the main course.

25L-45L

There are cats and dogs dolls, mainly for family use, with strong practicality.

▲38L household electric oven

For an average family of 3-4 people, at least 25 liters, less than 25 will not be considered.

What is the concept of 25 liters? When barbecuing chicken, you won't touch the top and bottom. Of course, you don't want to get stuck on the inner wall when you rotate the roast chicken in all directions. Ok, please make up the traces of oil stains yourself.

▲ This is not a broiler or 25L, please understand the spirit.

This capacity range can basically meet all baking requirements, and friends can show their skills when they come to dinner.

45L-70L

Often used, and the kitchen is big enough.

Suitable for large families with 5-7 people, more food can be baked, and the food is heated more evenly, because the temperature difference between the place near the heating pipe and other places is quite large, and the larger the oven space, the more evenly heated it is.

It is inevitable that ovens of this size will be table-top, so most manufacturers design embedded ovens, which are embedded in the whole cabinet and do not occupy additional kitchen space.

Many people have seen various foreign pictures, ins pictures, and most foreign ovens are embedded. As a result, they can't use it several times, wasting money.

Therefore, the average family's 25L-45L desktop oven can fully meet the demand, and families with more cooking or larger kitchens can also choose embedded ovens.

Square or flat

Most ovens are long, because baking the same food can only be placed left and right, not up and down. What size baking tray can be placed horizontally and how much food can be baked is the most important.

There are also some square ones, which are slightly narrower in width but higher in height, so that you don't have to worry about the easy swelling of the top of the food, and you can also bake different ingredients on the upper and lower floors at the same time.

▲ Toffy electric oven and coffee machine in Japan.

* It should be noted that some salesmen will fool you in order to make you buy something bigger and more expensive.

For example, you can bake 10 cookies horizontally, and the salesperson will tell you to put three layers, so you can bake 30 cookies, but the actual situation is that cookies must be baked in the middle of the oven! Put it on the top, the top is burnt, the bottom is not ripe, put it on the bottom, the bottom is burnt, and the top is not ripe.

Wall lamp and visual door panel

Wall lamp is a very small and timid thing, but it is very powerful. To make up for it, you set the temperature and time strictly according to the recipe requirements when baking, but it still failed.

Because there is no wall lamp, it is impossible to observe the baking situation when necessary. You can't see the effect until the time is up. Of course, you can choose an external strong flashlight to make up for it.

▲ Explosion-proof wall lamp

The function of visual door panel is similar to that of wall lamp, so you can experience it yourself.

Although most ovens have wall lamps and visible door panels, you still need to pay attention.

heat capacity

In fact, regardless of the size of the oven, the principle itself is very simple, that is, a box with electric heating tubes.

Heating speed, is the edge and center of the oven evenly heated? These are the places that reflect the performance gap of the oven.

Two heating pipes

15L small ovens generally use only two electric heating tubes, and the heating speed is slow when they are put on and off. However, the oven space itself is not large, and two pipes are enough, which is easy to cause baking because of the high temperature.

▲ Two heating pipes

Four or six heating pipes

Four tubes and six tubes are mostly used in ovens over 25L, which are evenly distributed up and down, which is often said to get angry. The more tubes, the faster and more uniform the relative heating speed.

Not only the number of heating pipes will affect heating, but also the shape of heating pipes will affect heating. There are generally straight tubes, U-tubes and M-tubes for household electric ovens in the market.

▲M-type heating pipe

For example, an M-shaped pipe is actually equivalent to four straight pipes connected, and the joint forms an elbow. Although the temperature at the bend will be higher, it has little effect on the overall surface heating. Compared with the straight tube, it can make the heating area in the oven larger and the baking color more uniform.

Temperature control capability

temperature range

The controllable temperature range of household electric ovens on the market is usually 70? C~250？ C, there will be 30 with fermentation function? C~250？ C, it is also more expensive, but the low-temperature function is basically only used for fermentation, and there is no demand and no need to spend more money.

difference in temperature

Besides, we can't avoid a problem. Basically, all household electric ovens have the problem of actual temperature deviation, which leads to the failure when baking strictly according to the temperature and time in the formula.

The method of detecting temperature difference is also very simple. Buy one or borrow an oven thermometer from a baking friend.

▲ Special thermometer for oven

Put the thermometer in the center of the baking tray and the baking tray in the middle of the oven, adjust the oven temperature to the highest, set the time for 30 minutes, check the real-time temperature of the oven thermometer in 20 minutes, and use the set temperature-measured temperature = temperature difference, and the international temperature difference is 30? C is within the normal range.

▲ Temperature difference detection

The better the oven, the smaller the temperature difference, but it can't be detected when you buy it back, so you can only buy it home for testing or buy a big brand online, and there is no reason to test it for seven days (but generally everyone is too lazy to return it ...).

Master the temperature difference of your oven, and you can adjust the temperature according to the temperature difference in the future, so you don't know the reason every time you bake.

store heat

Another factor to control the temperature is the heat storage capacity of the oven. For oven doors that are frequently opened and closed and have a large area, there is a great difference between double-layer glass and single-layer glass. Double glass doors are more energy-saving and safer, and single doors are easy to dissipate heat from the crack of the door.

▲ Double tempered glass door

The oven itself uses heat energy to heat food, so it is recommended to choose double or multi-layer glass doors.

safe

Safety has always been the most important issue. When some ovens work, the shells and doors are so hot that they dare not go near them at all, let alone how dangerous it is for families with children. There are even cases where the oven door of a single glass panel bursts.

▲ Visible glass door burst.

Also check the opening and closing of the door. If the door is closed too tightly, it is likely to hurt people. If it is too loose, the natural safety will be greatly reduced. These can be directly checked and verified before buying in the store. Students should not be afraid of trouble, but they should use themselves in the future. Safety comes first.

clean

Students who have done baking should know that cakes will swell during baking. Too many raw materials were put in the beginning. If you are not careful, the cake will suddenly jump on the box, waiting for you to bake and clean. ...

In fact, the general oven design will pay attention to the use of easy-to-clean materials or liners, stainless steel, enamel or other materials. Food residues in the oven are generally most likely to appear at the bottom of the oven, so when purchasing, you should choose an oven with a removable chassis design at the bottom, which is convenient for disassembly and cleaning.

▲ External removable chassis

price

Because of different sizes and functions, the price of ovens ranges from 100 yuan to 10000 yuan or so. You can sit in the right position according to the above distinction, choose your suitable size and function, and then choose an acceptable price.

Different heating principles

The oven bakes the food by raising the temperature in the box through the heating tube, while the microwave oven generates electromagnetic waves through the food through the magnetron under the excitation of the power supply, and polar molecules (water, fat, protein, sugar, etc. ) is attracted and oscillates rapidly to heat food.

▲ microwave oven heating principle

Simply put, the oven heats food from the outside to the inside, while the microwave oven heats food from the inside to the outside.

Different baking effects

Heating in the oven will retain the moisture and nutrients contained in the food, and the food tastes better. However, in the microwave oven, the moisture and nutrients of the food itself will be seriously lost during heating, and the taste will naturally change.

Different heating rates

Everyone has used a microwave oven to heat food quickly, but it takes 30 minutes to bake a cookie in the oven, not to mention the preparation work. If you are not used to it, you should honestly choose a microwave oven or take-away.

pass

You don't want to buy anything bad, and the oven is no exception. Before purchasing, carefully check whether the product parts, knobs and buttons are firm, whether the plug wires are damaged, whether the door switch is smooth, whether the hardware is burr-free, and whether it feels good. This is a cliche, you can pay attention to it yourself.

fixed

Ordinary desktop ovens can be placed directly on the kitchen table, close to the power supply, and it is best not to put them on the plastic table, which is easy to cause if the temperature is too high.
