Common Sense of Purchasing Stainless Steel Thermos Coffee Pots

Common Sense of Purchasing Stainless Steel Thermos Coffee Pots

At present, there are many varieties of stainless steel coffee pots on the market and the prices vary greatly. Some consumers do not understand the reason. They often spend a lot of money but cannot get satisfactory products. Now we will give an introduction to the purchase method of stainless steel coffee pot.


1. Pay attention to the label or manual of the stainless steel thermal coffee airpot


Usually the regular manufacturers will write the product model, name, volume, material, production address, manufacturer, standard number, after-sales service, usage method, etc. If these are not present, there is a problem.


2. Appearance identification of stainless steel thermal coffee airpot


(1) Check whether the surface of the inner and outer container of the coffee pot is uniformly polished. Whether there are bruises, scratches or burrs;


(2) Check whether the welding of the spout of the coffee pot is smooth and consistent, which is related to whether the customer is comfortable drinking water;


(3) Check whether the seal inside the coffee pot is tight, and whether the screw plug matches the cup body;


(4) Look at the spout of a stainless steel coffee pot, the rounder the better. The process is not yet mature and there will be out-of-round conditions.


3. Sealing test of stainless steel thermal coffee airpot


Twist the lid down first to see if the lid fits perfectly with the stainless steel airpot coffee pot, then add boiling water (preferably boiled water) to the pot, and turn the coffee pot upside down for 2 to 3 minutes to see if any water seeps out.


4. Insulation performance test of stainless steel thermal coffee airpot


Because the stainless steel coffee pot uses vacuum insulation technology, it can prevent heat from being transferred to the outside under vacuum conditions, so as to achieve the effect of heat preservation. Therefore, to test the heat preservation effect of a stainless steel coffee pot, you only need to pour 100°C boiling water into the pot. After two or three minutes, touch the various parts of the stainless steel coffee pot to see if there is hot air. If any part of it gets hot, the temperature will be lost from that place. Normally, there will be a slight heat in the spout area.


5. Plastic logo of stainless steel coffee pot


All plastics used in stainless steel coffee pots should be food grade. This kind of plastic has low odor, bright surface, no burrs, long life, and is not easy to age. Compared with ordinary plastics or recycled plastics, which has a big smell, dim color and more burrs, prone to ageing, easy to break, and smelly after a long time. This will not only shorten the life of stainless steel coffee pots, but also threaten our health.


6. Inspection of the capacity of stainless steel coffee pot


Since stainless steel coffee pots are double-layered, the actual capacity of the pot is different from what we have seen. The first thing to look at is whether the height and depth of the outer layer of the inner tank are not much different (usually 18-22 mm). In order to reduce costs, many small factories often start from the raw materials, which may affect the capacity of the stainless steel coffee pot.


7. Identification of stainless steel material of stainless steel coffee pot


There are many varieties of stainless steel materials, of which 18/8 means that the stainless steel material contains 18% chromium and 8% nickel, which meets the national food-grade standards. It is a green product with anti-rust and corrosion resistance. Generally, if the stainless steel material is whitish or dark and produce rust spots after being soaked in 1% salt water for 24 hours, the content of the stainless steel will exceed the standard, which will directly endanger human health.


When buying a stainless steel coffee pot, don't just look at the appearance or name, but pay attention to whether it is double-layer insulation or vacuum insulation on the manual.


Nowadays, many stainless steel coffee pot products are elegant in appearance and novel in style. In fact, they are double-layer insulation without vacuum. Therefore, consumers are reminded not to make such small mistakes and should read the outer box instructions and product manuals clearly.
