Kitchen cookware should you know
Divided by function cookware pressure cooker, frying pan, fry pan, stockpot, steamer, milk pan, multi pan, etc.; material divided by stainless steel pot, pan, aluminum pan, casserole, copper pots, enamel pots, pans, composite material pot; handle the number of points according to one ear and both ears pot pot; by the shape of sub-bottom pan and the round bottom pot.
Pressure cooker
Press material can be divided into aluminum pressure cooker pressure cooker and stainless steel pressure cooker. By closing lid can be divided into screw type, gland type and the drop cap style. The most common market for the screw type.
Pressure cooker in accordance with the national standard GB13623 -92 and GB15066-94 required to be equipped with three types of safety devices: pressure limiting device, safety pressure protection device and pressure protection device to open and close lid.
The role of the pressure limiting device in the heating process the pressure to work pressure pot, pressure limiting valve through the exhaust vent to work to avoid the pressure continues to rise, reaching cooking purposes, attempts to prevent the pressure limiting valve on the bottom cover to Prevention of food blocking voltage limiting vent.
Safety pressure protection device often fusible chip, when the pressure exceeds the pressure of work due to limited pressure vent valve plug or other reasons do not work, the fusible film is not more than two times the working pressure and melt through the exhaust pressure, to avoid pressure cooker damage, thus protecting the user's safety, the safety of the pressure cooker is a lot of protection devices have already switched to the spring structure, the pressure rise when the top springs open exhaust, also played a relief role.
Pressure protection device to open and close lid is usually located in the handle and lid combination of the place. Its role has two, one when the lid is not fully deducted timely, not to pressure increases, because the fastening strength of the lower lid at this time, if the heat so that the pressure rise, pressure cooker might explode. Second, when the pressure pot pressure is not down to security, the guarantee not to neglect the user opening the lid.
Select a pressure cooker to note the following.
Aluminum pot
Aluminum pan and lightweight, durable, quick heating, heat evenly, does not rust, but should not be used to cook acidic or alkaline food and salty food, otherwise, will be cooking in a large number of dissolution of aluminum contamination of food. Numerous studies show that excessive intake may accelerate the aging of aluminum and aluminum or lead to the root of Alzheimer's disease.
It is understood that aluminum products mainly refined aluminum (soft aluminum) products and aluminum (hard aluminum) products are two kinds of materials for the aluminum and aluminum alloys. Surface color can be divided into white, light yellow and other colors. White aluminum products are divided into two kinds of casting and stamping. Cast aluminum surface by the car light and mechanical polishing, the surface of white, but the metal structure loose, there are some casting defects. Stamping of aluminum products, whiten the surface, sanding and machine polishing, the surface natural oxide film thickness of only 0.01-0.15 μm, thin and uneven, it is easy to mechanical abrasion or wear. The yellow aluminum is anodized stamping products, to generate a light-yellow surface of artificial oxide film. Oxide film thickness generally 5-20μm, uniform and compact, the strong base effect, the 100 seconds the film is not damaged. Therefore, the best light yellow aluminum products, it has a beautiful, easy to remove dirt, and strong corrosion resistance, wear resistance characteristics.
Everyday life, many people prefer to use steel ball to highly polished aluminum pan bottom, experts say that while erasing the stain on the pot, but also wipe the surface of aluminum cookware has a protective effect of oxide film . Therefore, the use of aluminum pots, aluminum pots and other aluminum cookware, you do not wipe the surface of the pale yellow rust.
Buying note
In the selection of aluminum pots, the pot should be noted that a round body is straight, bottom of the pot, lid, and internal and external light, not dark, black scar, or cracks, and components to examine the structure, such as rivets, solid ring is first-class department, with or without anesthesia point, trachoma.
Stainless steel pots
Stainless steel cookware, beautiful appearance, fine structure, while a durable, corrosion resistant, rust-proof, easy processing, deformation, etc, is cooking the market mainstream. However, stainless steel pots and pans heat unevenly, many brands of stainless steel pot with a bottom layer of composite structure, and some brands also use the whole body three composite structure. Three composite structure is generally a layer of aluminum two stainless steel clip to a high-tech molding process, so that even heat cookware, heat quickly, will not pot a single point temperature is too high and burnt food, but also not easy to produce fumes, generally have fried, fried, grilled, stewed and many other features. Composite structures using the three-pot, can fully maintain the nutritional content of food, but also to maximize the maintenance of the health of housewives.
Stainless steel cookware is not a long bloom salt, soy sauce, vinegar, soup, etc., because these foods contain a lot of electrolytes, if the time is poured into, then the same will be like stainless steel, like other metals, and these electrolyte from the electrochemical reaction, so that toxic metal elements are dissolved out.
Can not use stainless steel pot pot medicine, because medicine containing a variety of alkaloids, organic acids and other ingredients, especially in the heat conditions, is difficult to avoid chemical reaction with, Er Shi drug failure, and even generate some of the more toxic complex.
Can not use strong alkaline or strong oxidizing chemical agents, such as soda, bleach, sodium hypochlorite, etc. washing. Because these substances are strong electrolytes, since the same electrochemical reaction with the stainless steel.
Buying Notes
Pot is good or bad lies in the bottom of the pot, sandwich bottom of the aluminum layer thickness distribution to be uniform. Some three-tier structure of stainless steel cookware aluminum composite thickness uniform, as both sides of the thin, thick and so the middle, resulting in uneven bottom heat. Structural design of the lid should be reasonable, better sealing. Convex lid design allows the natural circulation of water, heat sealing so that the loss is not easy. Otherwise hot handle, easy to handle because of easy to hot aging.
To select a suitable gas stove, electric stove, microwave oven and other appliances used in stainless steel cookware.
Non-stick
Non-stick handsome in appearance, novel, non-stick, non-paste, easy to clean, washable, odorless. Common substrate with non-stick aluminum, iron, stainless steel and alloy. Non-stick layer is coated, cast film. Non-stick coating material mainly ordinary non-stick coatings and advanced Silverstone non-stick coating, good non-stick coated cookware can completely tightly put a little oil or oil only under cooking food. Cast film is PTFE material, with heart bypass surgery is the same material used. Casting non-stick with the fried, fried, stewed, baked and other functions, under normal cooking does not produce smoke, pot roast with water from time to time.
Non-stick using the higher, not with a spade, shovel and other hard objects scratch steel boiler body, things can not be cleaned with wire pot body, which can not raging fire.
Buying Notes
To select the name brand non-stick cookware to large shopping centers. In contrast, whole body thicker materials and consistent non-stick pan, food can be a relatively constant temperature of the state, not the loss of nutrients, flavor pure.
Casserole
Casserole suitable for stew, soup and fried Chinese medicine, but the casserole's enamel contains a small amount of lead, dissolved easily when cooking acidic foods out, harmful to health, it is best to use natural-colored wall casserole. Color of the inner walls of the casserole should not be stored wine, vinegar and acidic drinks and foods. The casserole may be the first new buy 4% of the vinegar with boiling water immersion, this would remove the most harmful substances.

Second, when the pressure pot pressure is not down to security, the guarantee not to neglect the user opening the lid.
Select a pressure cooker to note the following.
- should buy a pressure limiting device, safety pressure protection device and the opening and closing of the pressure cooker lid pressure protection device. In particular, the market still not open and close a large number of old-fashioned cover the pressure cooker pressure protection device, the pressure cooker has been eliminated, is incompatible with the current national standard.
- should choose as needed. Aluminum pressure cooker heat fast, even heat; stainless steel pressure cooker beautiful, clean and wearable, but the slow heat conduction, heat concentrated, easy to paste the end, but some increase in stainless steel pressure cooker complex, better performance.
- pressure cooker should pay attention to the appearance of quality. Pressure cooker produced a number of individual vendors working rough, pot body edge burr, advised consumers to stores to buy a large manufacturer of products. Also note the time of purchase whether the products are trademark, name and address, the best pressure cooker to see whether there is technical supervision of the inspection report issued by the department.
- pressure cooker along with the extension of service life, its overall strength will decline, according to state regulations, the maximum useful life of a pressure cooker for 8 years, who extended the use of pressure cooker pressure cookers are safe, must be replaced.

- see pot surface. Pot is smooth, but does not require smooth as a mirror, the surface has irregular light pattern is normal, but if the lines are too close, it is defective.
- observation point. "Small bulge" used wheel wore off, "fossa pit" of poor quality, some of those who used to sell pot graphite the "eyes" fill in, not easy to detect, only a few with a small brush to expose them.
- check the bottom of the pot. Bottom of the pot smaller, faster transmission of fire, provincial fuel, save time.
- Check the thickness. There Baohou divided pot to thin as well, identification may be bottom of the pot overturned, finger withstand concave center, with a hard object hit, the louder sound of pan, shaking fingers, the greater are the better.
Kitchenware shopping tips
Facing market in numerous brand design kitchen electric appliance, how should we choose most suit our kitchen electric appliance? If you are not understood very much to the kitchen electric appliance's related knowledge, possibly must spend even wastes the very long choice time. How therefore masters certain specialized knowledge to select and purchase the kitchen electric appliance to you to have certain necessity, the kitchen expert tells you to select and purchase time several kind of commonly used kitchen electric appliance's matters needing attention:
Range Hood: fume extraction effect, cleaning convenience
As an essential kitchen cleaning tool, the effect of fume extraction hood must be good or not consumers are the first to consider the conditions. In general, smaller than the recent European smoke suction suction smoke machine, but as long as the displacement of 11 cubic meters / minute or more, that is, large suction hood, to meet the needs of ordinary families.
In addition, the cleaning hood has been the problems plaguing consumers, no matter how good the hood, no matter how their advertising nonstick oil-free washable, without a fume purification devices or purification process is bound to be contaminated by soot . Now many users complained that: the beginning of a new range hood to buy the work, the smoke effects and noise are normal, can run for some time, the noise increases, exhaust volume also decreased. This is mainly hood fan turbine fan page by condensation of the grease by the adhesion, over time, the fan turbine fan page of dynamic balance is destroyed, the result not only increases the fan bearing resistance and noise, and affects their life. Therefore, cleaning of range hood is the purchase of routine maintenance work after the main work. Users purchase, which should be used without any special tools, you can always wash their own. Side of the range hood cleaned at any time as long as the oil network, you can maintain a smoke machine to work properly. Should also carefully observed the surface of the hoods cooker hood should not have seams, (preferably a whole stretch forming of Health does not stay dead) for a more thorough and easier cleaning.
Gas stove: The stove fire is not necessarily good
In the minds of many consumers there was a misunderstanding: the greater the gas fire stoves, the better. In view of this mental errors, some merchants began to fire big advertisement of their products, energy efficient. However, the greater firepower, on behalf of the greater air consumption per unit time, so-called large and energy-efficient fire is untenable.
Gas engineers after long-term study found that household gas stoves embedded control the heat flow between the 3.5KW-4.0KW, can fire large enough, while the higher thermal efficiency, combustion stability sufficient to achieve the optimal balance point of combustion.
Therefore, consumers should pay attention to gas stoves, the product of heat flow (fire) must be greater than 2.91KW (GB), but not more than 4.0KW; sufficient degree of combustion (CO emissions) must be less than 0.05%; extinction valve closure time automatic protection device should be less than 60 seconds. Meet these standards is the high-quality gas stove.
Disinfection cabinets: to know ourselves and to bed of roses
With the improvement of living standards, disinfection cabinet using more and more families, but not all are aware of their own prior to purchase what kind of style. Experts advise you to purchase such products should be determined according to the specific circumstances of the family.
First of all, according to population. Based on years of market research, if your family members do not exceed four, choose 42-90 liters of Disinfection cabinet, more than four, options for more than 90 liters of product.
Furthermore, according to tableware texture. If your home is to use ceramics, high temperature glass, stainless steel tableware and other high temperature, can be used with high-temperature sterilization room Disinfection cabinet; the family often baby bottles, plastic cutlery, plastic toys, etc. need to disinfect, then use with Ozone sterilization disinfector better.
In addition, scheduled to be placed according to the decision. Most families will disinfect cabinet placed in the kitchen, it should be used to disinfect stainless steel cabinet, these products are corrosion-resistant, easy to clean; a small number of consumers will need to be disinfected for personal display cabinet in the living room, reception room or office, etc. to, then select the static spray, or disinfection cabinet with glass doors will look nice.
Reputation
Selection of kitchenware in fact of reputation is also important, a brand recognized by the general public is more reliable than any publicity, consumers in understanding details of a product before, best to recognize their brand, to understand whether the quality of services. Integrity Services is one of the more perfect one, strong customer is God's faith, the implementation of pre-, during and after sales, returning full-service, effectively solving the customer's worries.
