What can a thermos cup hold? What can be held in a thermos cup

Everyone knows that the thermos cup can hold hot water, 90 degrees of water can be kept warm for 6 to 12 hours, and 60 degrees of water can be kept warm for about four hours. Generally, everyone uses thermal insulation to hold hot water, in fact, there are many uses for thermos cups.

First, the thermos cup can hold meals. When you go out to play, or go to work in the unit, when the mother takes the baby to the playground to play, you can use the thermos cup to fill some meals. Keep warm and keep it fresh.

When your child is hungry, you can give your child a meal in time, and you don't need to replace it with snacks.

Second, the thermos cup can be put with soy milk. Nowadays, office workers are getting busier and busier, and when you get up late in the morning, you can make an appointment to polish the soy milk in advance, and then pour the soy milk into the thermos cup in the morning, and you can take it directly to the unit for direct drinking.

Third, the thermos cup can also put cold water, he can maintain a certain coolness, like people working outdoors, or go out to play, especially suitable for mountain climbers, when you climb up the mountain to the halfway point, you are thirsty and want to drink some cold water, and it is not easy to buy it down the mountain, you can drink the cold water in the thermos cup.

Full-time mothers of the second child born in the 90s, here is the experience of the second child, super parenting dry goods.

The thermos cup can be filled with hot water, because the most important function of the thermos cup is to hold hot water, and its good heat preservation function can allow people to drink warm water in a cold environment. The thermos cup can also hold meals, although the thermos cup is relatively small, it can't hold much food, but if there is no thermos lunch box at home, it is okay to use the thermos cup for emergency.

The thermos cup is generally a container for water made of ceramic or stainless steel plus a vacuum layer, with a lid on the top and a tight seal, and the vacuum insulation layer can delay the heat dissipation of liquids such as water installed inside, so as to achieve the purpose of heat preservation.

The thermos cup is developed from the thermos flask, and the insulation principle is the same as the thermos flask, but people make the bottle into a cup for convenience.

There are many layers in the thermos cup, its interlayer is generally vacuum, to prevent heat conduction, and then plated with silver, so that heat radiation can be blocked, and some cup lids have corks on them, which is also to prevent heat conduction.

What can and can't be loaded into a stainless steel thermos cup?

Dear, hello, I am glad to answer for you What can and can't be loaded in a stainless steel thermos cup? A: It's best not to pack anything but water.

Although it has no effect on people after drinking, it is not good for the cup, and different things have different substances, so I am afraid that some substances will have a bad effect on your cup. 1. Don't make tea Most of the thermos cups on the market are sealed to achieve the effect of heat preservation, and for tea, soaking in a closed hot water environment for a long time can easily cause the loss of nutrients such as tea polyphenols, and the taste will also decline, and even the tea will ferment to produce harmful substances. 2. Don't put "acidic" drinks It mainly refers to "acidic drinks" such as fruit juice and fruit vinegar.

Because the "acid" in these drinks corrode the thermos cup, what "heavy metals" will be precipitated in the drink, which will be harmful to the human body. 3. Don't fill milk Many people choose to fill a glass of hot milk in a thermos cup in the morning because they don't have time to eat breakfast, and take it with them to drink. However, milk and other dairy products will produce harmful substances when they come into contact with the stainless steel material in the thermos cup.

The high temperature environment of the thermos cup will cause the milk to deteriorate quickly, and it is easy to cause abdominal pain, diarrhea and other symptoms after drinking. 4. Do not pretend to be traditional Chinese medicine Due to the large and complex ingredients, traditional Chinese medicine is easy to corrode stainless steel material in a thermos cup, produce harmful substances, and cause adverse reactions after drinking. Recommendations:

The decocted Chinese medicine can be stored in an environment of 25 for 1-2 days, and it is recommended to store the Chinese medicine in a room temperature environment.

The 304 and 316 stainless steel mugs are safe to use.

The qualified thermos cup liner is made of food-grade stainless steel 304 and 316 materials, 316 material is lighter, more resistant to high temperatures, and more corrosion-resistant, but the cost is also higher. Straws, seals and accessories are generally made of Tritan, PP and food-grade silicone, which are safe and usable.

304 is a versatile stainless steel that is widely used in equipment and parts that require good overall properties (corrosion resistance and formability). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced in accordance with the American ASTM standard.

The thermos cup can only be filled with boiling water, and porridge or soup is not suitable for being placed in the thermos cup, and these acidic substances will cause damage to the inner tank of the thermos cup and affect the thermal insulation effect of the thermos cup. Although the thermos cup cannot be filled with acidic liquid for a long time, it can also store weakly acidic beverages such as coffee for a short time of one or two hours, which will not cause damage to the liner coating of the thermos cup. Although the thermos cup is very good, some liquids cannot be filled, so what can not be soaked in the thermos cup, what can not be filled in the thermos cup, let's learn more about it Let's learn more about it The thermos cup cannot contain acidic drinks The thermos cup cannot be soaked in acidic drinks, such as sour plum juice, lemon juice, etc.

Due to the high melting point of stainless steel, it will not release undesirable substances due to high temperature melting, but stainless steel is most afraid of strong acids, and if it is loaded with acidic drinks for a long time, it is likely to damage its inner tank and cause poor heat preservation. In addition, fruit juice should not be stored at high temperatures to avoid damage to its nutrients; And beverages with high sweetness are easy to cause a large number of microorganisms to breed and deteriorate. The thermos cup should not be filled with dry ice, and the thermos cup should not be filled with dry ice and carbonated beverages to avoid the danger of rising internal pressure, resulting in the inability of the cork to be opened or the contents to be sprayed.

Some people will put hot milk in the thermos cup to facilitate the use of hot milk, but this practice allows the microorganisms in the milk to multiply rapidly at the right temperature, resulting in spoilage, which is easy to cause diarrhea and abdominal pain. In the high temperature environment of milk, vitamins and other nutrients will be destroyed, and the acidic substances in the milk will also react with the inner wall of the thermos cup, affecting human health. If you use a thermos cup to make tea, so that the tea leaves are soaked in high temperature and constant temperature water for a long time, just like decoction with warm fire, a large number of vitamins in the tea are destroyed, aromatic oil volatilization, tannic acid, theophylline a large number of leaching, not only reduce the nutritional value of tea, but also make the tea juice fragranceless, tea bitter taste, and even because the steeping time is too long, the tea may release heavy metal substances, harmful to health.

In addition, the thermos cup will change color when the hot tea is kept warm for a long time, so it is recommended to use tea bags to brew when going out. The thermos cup cannot be soaked in traditional Chinese medicine, and some people also like to soak traditional Chinese medicine in the thermos cup to facilitate carrying and drinking. However, the decoction of Chinese medicine generally dissolves a large number of acidic substances, which is easy to react with the chemicals contained in the inner wall of the thermos cup and dissolve into the decoction, which has adverse effects on the human body.

Traditional Chinese medicine can be stored at a temperature of 25 for one or two days, and the temperature in the thermos cup is high and easy to deteriorate, so it is recommended to store it at room temperature. The thermos cup can not put salt in the liquid thermos cup can not put salt in the fluid, such as salt water, because the inner tank of the thermos cup is sandblasted and electrolyzed, and the electrolyzed inner tank can avoid direct contact between water and stainless steel material Physical reaction, and salt contains corrosiveness that may cause damage to it, and it is not suitable for long-term installation in the quilt.
