In kitchen appliances, the material of a defrosting tray directly determines its defrosting In kitchen devices, the material used to make a defrosting tray determines its defrosting performance, safety, and longevity. For others who want to optimize the kitchen, using the optimal material for a defrosting tray will make food preparation even more convenient. So, what is the “best” material for a defrosting tray? In today’s article, we’ll examine this topic more closely and learn why the KAYUSO fast defrosting tray became the benchmark in the industry because of its premium materials.
Comparison of the Most Common Defrosting Tray Materials: Which One Is the Best?
There is a wide variety of defrosting tray materials found in the market, and their performance is extremely different. Let us consider their advantages and disadvantages one by one:
Common Metal (e.g., Aluminum, Iron)
Metal is a common heat conductor, and defrosting trays were made from this material in the past. While its advantages are inexpensive and rapid heat transfer, its disadvantages cannot be underestimated either: It may easily rust with age, especially after contact with water and food juices, potentially emitting toxic contents in the process. Asymmetrical heat transfer can lead to some food freezing too rapidly in certain sections, which adversely affects flavor. There are no antibacterial characteristics, so it is extremely prone to growing bacteria while thawing. Defrost trays made of this material are more appropriate for short-term applications and lack long-term, safe kitchen requirements.
Plastic
Light in weight and clean-up, plastic thawing trays are a faulty product with a lethal weakness of low thermal conductivity, leading to slow thaw rates. They tend to need hot water or the microwave, making the whole point of fast thawing pointless. Plus, inferior plastics may release plasticizers when heated at high or exposed to oils, creating a food safety hazard.
Ceramic
Ceramic is also good-looking and heat-resistant, but heavy, brittle, and has far worse thermal conductivity than metal with long thaw time and lower use. Also, the ceramic surface easily picks up food residue and odors and is difficult to clean.
Composite Thermally Conductive Material (Used by KAYUSO)
Composite thermally conductive materials are a recent innovation. They combine the advantages of multiple materials, such as a high-thermal-conductivity metal with a food-grade antimicrobial layer. This ensures efficient heat transfer while addressing safety and durability. Thawing trays made of this material are becoming mainstream in the market—and the KAYUSO Rapid Defrosting Tray is a prime example.
KAYUSO’s Material Advantages: Why is it the “ceiling” of thawing trays?
KAYUSO understands the importance of materials for thawing trays and has therefore comprehensively upgraded its material selection and craftsmanship, achieving the trifecta of “efficiency, safety, and durability”:
- Aerospace-grade composite thermal conductive layer, increasing thawing speed by 300%
KAYUSO’s core material is an aerospace-grade aluminum alloy composite layer, which has a thermal conductivity over three times that of ordinary metals. It quickly absorbs heat from the air and evenly transfers it to the surface of the food, thawing frozen ingredients simultaneously from the outside in, avoiding the “cooked outside, raw inside” problem of traditional thawing. Data shows that thawing a 500g steak using a KAYUSO takes just 12 minutes, while a standard metal tray would take over 40 minutes.
- Food-grade antibacterial coating eliminates safety hazards
In addition to the composite heat-conducting layer, KAYUSO has specially applied a food-grade nano-silver antibacterial coating. This coating effectively inhibits the growth of common pathogens such as E. coli and Staphylococcus aureus, with an antibacterial rate of up to 99.9%. Even if juices form during thawing, there’s no need to worry about bacterial growth, ensuring food safety.
- High-temperature and corrosion-resistant, with a 5-fold longer lifespan
Ordinary metal trays can rust and warp after just six months of use. However, KAYUSO’s composite material has undergone 1,000 high-temperature freezing cycles and maintains stable performance in environments ranging from -20°C to 120°C. Whether handling frozen food or using hot water for washing, it will not deform, peel, or corrode, resulting in a lifespan far exceeding that of similar products.
- Ergonomic, non-slip design: a double upgrade in both material and experience
Beyond the core material, KAYUSO also incorporates subtle details: the tray’s edges are rimmed with food-grade silicone, which is both non-slip and scalding, making handling safer. The matte finish resists water and oil stains and cleans easily with a simple wipe, putting an end to the worry of “washing trays is more tiring than cooking.”
