Getting to Know Induction Cooking and Induction Cookware

Published February 25, 2017 in Cooking , Science & Technology - 0 Comments

Cooking with induction appliancesWe usually prepare food by cooking. Cooking is the process of making our food through heating. When cooking indoors, cooktops and ovens are often used, though sometimes, grills and griddles are used to prepare food.

Cooktops are divided as gas types and electric types. Electric-types, however, do have more accurate methods of heating by electricity. This includes coil elements, halogen heaters, and induction. In this article, we will be discussing more induction cooking.

Induction cooking also uses induction cookwares so if you are looking for some, check out the best induction cookware reviews to get ideas.

What Is Induction Cooking?

Coil and halogen heaters generate heat from electricity and transfer this heat to the cooking vessel to cook the ingredients in it. However, induction cooking is different from this method. It doesn’t generate heat to be transferred to the vessel.

In an induction cooking, it is the cooking pan/vessel itself which generates heat.

The “heating zone” in an induction cooker is a powerful electromagnet that generates high frequency (20-40 kHz). When a magnetic material (induction cookware) is placed in that zone, the electric field induces energy into the metal, generating heat on it. The heat that the cooking vessel is controlled by the strength of the magnetic field. The stronger it is, the more heat is produced by the cookware.

How Induction Cooking Works

1. The coil of metal, which colors red when turned on, provides an invisible high-frequency electromagnetic field.

2. No heat is produced in the heating zone until the pan is placed on it.

3. When the pan is put in the cooking area, the electromagnetic field penetrates into the induction cookware, and electric current starts circulating the pan, generating heat.

4. By conduction, the heat of the cookware then heats the contents in it.

5. When the pan in removed from the cooking zone, the field stops generating heat.

In an induction cooktop, only when an induction cookware is placed on the coil metal area does heat starts to produce.

Cookware Used in Induction Cooking

Though they can be used in gas and electric stove for the kitchen, induction cookwares are purposely made for induction cooking. These are made from magnetic materials like steel, iron, and magnetic stainless steel. Ceramic clad, and other pots and pans with enamel coating can also be used on induction cooktops because of the iron pan which is hidden inside the ceramic layer.

Pots and pans made from copper, aluminum, and glass cannot be heated in induction cooktops because it doesn’t have a magnetic material which the electromagnetic field flows to generate heat.

If you’re not sure whether your cookware has a magnetic material or not, get a magnet and place it on the bottom surface of your cookware. If it sticks, then it is magnetic and therefore can be used in induction stoves.

Review:

Induction stoves do not generate heat and transfer them to your cookware. Instead, it generates a high-frequency electromagnetic field which transfers to your cookware made from magnetic material. When the electromagnetic field is circulated in the vessel, it then starts generating heat. In an induction cooking, it is the cooking vessel itself that generates heat.

The Best Binoculars For Recreational Use

Published November 22, 2016 in Science & Technology - 0 Comments

binoculars-being-usedWhether hunting, fishing or hiking; what is the one thing you wish you could enhance? Your vision. Therefore, you are selling yourself short if you are hunting, fishing or hiking with binoculars. Binoculars are designed to magnify distant objects. You will need a pair of field glasses to help enhance the wildlife and beauty that you cannot see with your own two eyes.

Most of the best binoculars come in a wide angle version to provide a greater field of vision for capturing movement. If the field of vision is small it is more difficult to find a moving image, which is typically the case when watching various sports. For this same reason, magnification is usually on the lower side, since higher magnifications cause the field of vision to narrow. Additionally, higher magnifications can provide less clear images since they magnify the effects of shaking hands and vibrating bleachers.

hunting-and-hikingAlthough they offer a narrower field of vision, you might also consider compact, or mini, binoculars for your next sporting event. These binoculars are smaller, lighter, and much more conveniently packed into a purse, bag, or even pocket. They can be much more convenient than carrying an average sized pair of binoculars, however the narrow field of vision can make it difficult to find moving images. They also tend to be a bit dimmer than their larger cousins, which can be a problem if you are using them in low light conditions.

When purchasing binoculars for sports and hobbies such as hunting, consider getting a durable pair that will stand up to the wear and tear of being carted around in bags and backpacks, dropped, and banged. Be sure to keep them in a case so the lenses don’t get scratched, and if possible get a hard case to keep them from getting banged up.

There are also some useful tips to keep your binoculars performing to their utmost for years to come. Remember, just because you choose the most durable pair of binoculars on the market, doesn’t mean that you can abuse them. As you have been searching for a new pair of binoculars, maybe your old ones were ruined? You will find the most common was binoculars become useless is from dropping them; so make sure you keep them on a strap wrapped around your neck. Also, keep them in a case, preferably a padded case. Keep the lenses covered so they don’t scratch, and always keep your binoculars clean. These tips should help them stay working like new.

How To Know If Your Air Conditioner Needs Repaired

ac-needs-repairedHow to know if your air conditioner needs repaired is a question that anyone who owns an air conditioning system will agree that there has to be periodic repair which needs to be conducted or carried out. This is an essential activity to be performed especially if you are keen to ensure that you keep your electricity bills in check. Apart from this, a routine service also helps in ensuring that you do not have to spend as much on repairs.

Most people think that if their system provides them with adequate cooling, there is no need for repair. This is not true, on the contrary, it is necessary to have it serviced on time. There is a possibility that some ice might build up on or near the air-conditioner system and result in leaking. Other common signs that show the need for repair is continuous running of the compressor or frequent cutting out of the same.

ac-repair-technicianBuild up of ice on the hoses are a strong sign that the system needs repair. If you have managed to notice such a problem, then you have the satisfaction of the fact that you will have repaired the system before the problem eventually becomes too large to be dealt with. The expenditure involved in air conditioning service is much more affordable than the cost of repairing it. It is better to nip the problem in the bud than have an air-conditioner that does not provide any cooling. An air conditioning service provider like the ones at TKAr Condicionado will send in a specialist who will be able to determine the problem with your unit and also repair it which will ensure that the system does not break down completely.

As mentioned above, if your air conditioner is running, but there is seeming no cooling in the room, you should opt for air conditioning service. This is needed for the obvious reason that the unit is not able to cool the room. Likewise, one of the most obvious signs of malfunction in your air conditioning unit is if your compressor refuses to cut off. All conditioning units are designed to cut off at the adjusted temperature. It ensures that the compressor does not get overheated leading to damage to the unit. This can be caused by a dirty air filter. But if your compressor refuses to cut-off, you can be sure that your unit needs repair which must be performed to as soon as possible. Continuous running of the compressor will not only damage your air conditioner but also cause your electricity usage to shoot up substantially.
