For Best Results in Maintaining Temperature.

Want to keep the contents hot or cold longer? The key is to preheat or pre-cool your vacuum bottle container. It is easy. Fill the container with hot water or cold water. Let it sit for five minutes. Empty and then refill with you chosen beverage or food. Do not use the microwave to heat your thermos vacuum bottle.

Cleaning

First, avoid two of the big mistakes. Don't wash it in the dishwasher. Wash by hand. Wash all parts in warm mild soapy water. Use dishwashing soaps like Dawn or Ivory or any other mild dish soap. Rinse clean before using. Harsh abrasive cleaners and scrubbers can damage or tarnish the finishes and inside of the containers. Over time, they can even change the flavors of the stored foods and beverages.

Second, avoid chlorine or bleach. Why? Chlorine and some other strong stain removers attack the rubber gaskets in your seals and lid. Over time, your thermos vacuum contents will begin to leak.

Stubborn stains like coffee and tea are removable. A couple of teaspoons of baking soda and warm water can be left inside. Let it stand open for one hour before rinsing thoroughly. On stubborn stains, soaking overnight produces excellent results. A bottle brush can be helpful.

Some prefer to use vinegar instead. Instead of baking soda, they mix 1 part white vinegar and 3 parts water. Let it set. The concentration can be stronger if necessary. On all cleaning, make sure to rinse very well with water.

Wash the outside with a soft, damp cloth or sponge and wipe dry. Now use it.

There are some off the shelf cleaning products available, but why not try using a home remedy before using a more expensive method.

To make such a container like a vacuum bottle,one way is to get a jar with foam insulation it wrapped up.The reason why the heat insulating material works,for two reasons.First of all,the foam plastics are poor conductors of heat.Secondly,the air is trapped in the foam is not conducive to the conduction of heat.Thus reducing the conductivity.Since the air is separated into tiny bubbles,foam insulation and therefore also play a role largely eliminate convection inside the bubble.Therefore,the heat transfer through the foam for the very small.

The fact that there is a better thermal insulator than a foam - vacuo.Vacuum bottle is no atom."Full vacuum"does not contain any atoms.To achieve the full vacuum is almost impossible,but can be done near vacuum,no atom,can completely eliminate conduction and convection.

There is a vacuum bottle evacuated bile.Thermos interior glass layer,while the surrounding glass vacuum.Glass gall easily broken,so the package it in a plastic or metal housing.Many thermos can actually unscrew and remove the glass gall.

Vacuum bottle also goes a step further.A silver-plated glass (mirror-like) to reduce the infrared radiation.Vacuum and silver combination significantly reduces the heat convection,conduction and radiation.

So why thermos things will eventually cool down?Because there are two paths thermos heat transfer.Among them is the big stopper,the other is glass,it is the top of the outer wall thermos where the transfer of heat to produce a path.Although the heat transfer through these paths is small,but not without.

Vacuum bottle know whether the liquid inside is hot is cold?I do not know. Vacuum bottle do is limit the heat conducted through the wall thermos.That can make a thermos to keep the temperature inside the liquid is almost unchanged for a long time,whether it is hot or cold.

Vacuum bottle are mostly adopt sealed type for heat preservation,due to the structure of the tea itself,can be fermented in airtight case,after fermentation of the tea will produce some harmful substances to human body.Tea is rich in protein,fat,sugar,vitamins and minerals and other nutrients,is a kind of natural health drink,containing tea polyphenols,caffeine,tannins,tea pigment and so on,and has many pharmacological effects.Tea leaves in hot water for a long time,like temperature decocting,tea polyphenol and tannin substances such as a large number of leaching,make tea color thick,with an indication.

Vitamin C and other nutrients in the water temperature exceeds 80℃ will be destroyed,high temperature and soaked for a long time will make its loss too much,which reduces the tea health care function.

At the same time,due to always maintain a high water temperature, the aromatic oil in tea can quickly a large number of volatile, tannic acid,theophylline,a large number of seepage,this not only reduces the nutritional value of tea,reduced the tea, also makes harmful substances.
