[Foam Thermal Insulation box] How long can the bubble box ice pack if the foam Insulation box is used?

Not only are the catering industry used insulation boxes, many other industries also use insulation boxes, such as fruit vendors and other industries.There are many types of insulation boxes. Which kind of Insulation box is good?The foam thermal Insulation box enters people's attention. Let's go to see what the use of the bubble Insulation box!

Introduction to foam Insulation box

The foam Insulation box is a kind of Insulation box made of foam. The structure of the foam thermal Insulation box is very simple, which is a cuboid, but there are small and small in size. Consumers can choose according to their own needs.The foam Insulation box has the function of insulation and refrigeration, so many people like and buy.

Bubble Insulation box material

Hair -available polystyrene foam plastic is a new central policy packaging material and insulation material.The foam Insulation box has the advantages of light gravity, impact resistance, easy forming, beautiful shape, bright color, vivid color, high -efficiency energy saving, low price, extensive use.

Bubble Insulation box price

The price of foam insulation boxes is very cheap, so many businesses choose foam insulation boxes.Pricing according to the size of the volume will not exceed 100 yuan. It can be seen how low the price of the foam heating box is.When using the foam Insulation box, try to avoid staining, because the foam Insulation box cannot be washed clean, so only abandoned.

Bubble Insulation box use 1

When we are busy at work, we usually eat or order meals at noon.Many restaurants use foam insulation boxes when they are delivered. The quality of the foam Insulation box is very light and will not cause additional burden on the meal.The foam Insulation box has a strong insulation function, so we can eat hot meals.

Bubble Insulation box use 2

Is the preservation method of "foam box plus ice pack" feasible?

For the current fresh e -commerce, money seems to have no shortage, but the problem is that the service has not kept up.A Norwegian fresh salmon, from processing to factory to the final delivery to consumers, needs to be rectified.How to ensure that fresh fresh e -commerce development is one of the biggest technical thresholds facing the development of fresh e -commerce.

"The whole cold chain" is the most important guarantee for fresh e -commerce foods. Construction and maintaining the cold chain require huge investment.In order to make up for the shortcomings of the cold chain, the combination of "foam box plus ice pack" has become the mainstream model of "last mile" currently distributed fresh products.However, this kind of fresh package is often mixed in ordinary express delivery. When the weather is hot or the delivery time, there will be the risk of ice -pack freezing and freshness.

For the current fresh e -commerce, money seems to have no shortage, but the problem is that the service has not kept up.

"Bubble box plus ice pack"

Is the process of fresh products experienced factory, transfer, and warehouses to distribution. Does the cold chain continue?The cold chain logistics of e -commerce built a self -built cold chain, or rely on third parties?

Fresh is all self -built cold chain logistics distribution, while Tmall Supermarket and originally lived in the cold chain at the same time, and also rely on third -party logistics distribution.In other words, except for the daily orchards that have not yet responded to this magazine, these four e -commerce companies have claimed that the fresh transportation process is the whole cold chain.

"If e -commerce has a self -built cold chain, during the process of fresh freshness, the temperature and humidity control will be more active and comprehensive.There are fewer cold chains. "Wan Qing consulting CEO Lu Zhenwang told this journal reporter.

Of the 45 volunteers in Beijing, Shanghai, and Guangzhou recruited by this magazine, a total of 68%of volunteers received fresh freshly distributed by the "foam box plus ice pack" insulation.

"At present, plastic foam box plus ice bag is still the mainstream of the last mile. This method is an upgraded version of the traditional 'cotton quilt' freshness.Cheng Leng Chain.

In Lu Zhenwang's view, the "cold chain" must include raw materials, processing, transfer, transportation, and sales of each link. Fresh methods such as plastic foam box plus ice pack can only be called ice.

As the largest cold chain distribution logistics dealer in Guangdong, a person in charge of the Weixi surname of the Guangdong region with a cooperative relationship with fresh e -commerce such as life, American kitchen, and good food has told reporters, "In the Pearl River Delta region, microThe special association will complete the freshness of the fresh chain within 24 hours, but the slightly far -farther northwest of Guangdong still needs to use foam boxes to add ice packs. "

Why can't the cold chain construction be fully covered?Lu Zhenwang believes that costs are the most critical factor restricting the construction of the cold chain."The refrigerated vehicle, the freezing library of temperature control and the maintenance of these equipment requires a lot of capital investment. It is impossible for ordinary players to afford it at all." He said.

Delivery methods are beneficial and disadvantages

The subjective experience process carried out by this magazine shows that SF is preferred to distribute the three -wheeled truck carried by refrigerated boxes, and the remaining four e -commerce companies are distribution methods for foam boxes and ice packs.For these two ways of distribution, the evaluation of the evaluation volunteers has each other.

Mr. Cheng, a Beijing volunteer, said: "The salmon feels fresh. There is no ice pack, but when I get the goods, I see the courier brothers picking it out of the car from the car."Although it was a separate packaging, it was still cold. "She expects the courier brother to just take it out of the refrigerator box downstairs.

Some consumers said that they could not adapt to the "naked packaging" of online shopping.Shanghai volunteers said: "Fresh freshness is not attached with ice packs, and it is the first time I am in the history of fresh online shopping in plastic shopping Bags." Ms. Li in Beijing proposed: "The weather is hot and can not cover the courier.Plastic Bags, if there is no brief preservation of ice packs, put it in the refrigerator in time. "

In this evaluation of this magazine, most of the express volunteers who received "foam box plus ice packs" were satisfied with it, but this packaging method was not foolproof.For example, this evaluation of fresh products sent to the testing agency. In addition to the preferred SF's SF, the other four e -commerce companies with foam boxes and ice packaging packaging have mixed with other ordinary express delivery.

"Generally, the heat preservation method of bubble boxes and ice packs can only be battered at 0 C ~ 6 C for four to six hours. When the weather is hot, or the courier is used as a normal express delivery, it exceeds the time limit of ice pack insulation. Fresh products have deteriorated products.Risks. In contrast, professional refrigerated boxes are more reliable and stable, "and the person in charge of Wu surnames in the Guangdong area of Guangdong pointed out.For example, the beef tendon and salmon sold by the Daily Orchards appeared in the laboratory of the third -party testing agency in this courier. The surface temperature of the beef tendon was 7 C at the time of opening the box, and the sandwich fish reached 9.2 C.

[Types of warm and warm box] Classification of cold and warm boxes of car warm and warm boxes and compressed locomotive refrigerators are better

Working principle

In addition to the "refrigeration" effect using semiconductor cooling boxes, it can also take into account the heating effect, but its "refrigeration" effect is far less than the refrigerator that uses the principle of compressor.It is only about 20 C than the ambient temperature, so it can only have the effect of cooling.

The refrigerator using the compressor is the real Car refrigerator. In addition to the fast cooling speed, some products can even reach -18 C's freezing capacity.However, its disadvantages are also very obvious. It does not have the heating function, the price is much higher than the warm and warm box, and at the same time, there are many restrictions such as direction (upside down) in the use.

Functional design

In addition to the different working principles, there are some differences in the functional design of these two types of car refrigerators. We also need to brighten our eyes to distinguish when selecting, so as not to affect the actual experience and effect.

Compared with the high price, using a compressed Car refrigerator with a compressed machine, the cooling and cold box of semiconductor refrigeration has absolute advantages in terms of price.At present, the price on the market ranges from tens to hundreds of yuan, and the low price can be accepted by most consumers.

The semiconductor refrigerator is also called an electronic refrigerator. It is different from other refrigerators that use compressors. The principle of semiconductor refrigeration is used. The principle of Parrad Patch is used by a smaller semiconductor chip.The medium -current circuit releases heat at the metal joint of the node when passing through the node, and achieves the ultimate goal of refrigeration and heating through different current flows.

When this semiconductor refrigerator is working, there is no vibration of any other mechanical components except the heat dissipation fan, and low noise, long life, and non -wear are also the biggest feature.However, its disadvantages are also very fatal in the eyes of many people. Compared with good heating ability, its refrigeration effect is poor and does not have the refrigerator of the compressor refrigerator. Generally, the ideal refrigeration temperature is only about 20 C.

With the continuous improvement of technology, some manufacturers upgrade the refrigeration capacity of traditional cold and warm boxes by increasing the area of refrigeration film, but it is still affected by the great ambient temperature. In addition to the refrigeration speed, it is better than using a single refrigeration system.Fast, there is no essential improvement in refrigeration ability.

Therefore, this kind of warm and warm box is more suitable for use in ordinary household cars. After all, compared with the more than the cabin of the cab, the space of the car is much smaller, and the air conditioning refrigeration effect is more obvious, making the working environment of the warm and warm box lower."Refrigeration effect" is more obvious.

In addition, we also need to pay attention when buying. At present, some vertical warm and warm box that supports the dual -use of the car households is used as a flat door design, and except for magnets on the door, there is no door lock.The sealing effect is easy to condense the moisture in the external air, so that the embarrassing situation of stagnant water around the refrigerator will seriously affect the daily use experience for a large vibration truck cab.Therefore, we should try to buy those who open the door and the bottom with a fully enclosed crooked warm and warm box.

The Car refrigerator that uses a compressor method is the same as ordinary household refrigerators in principle. The process of continuous circulation such as compression, condensation, expansion, and evaporation of internal refrigerant is used to reduce the internal temperature inside the refrigerator.It is just out of portability, and its volume will be even more compact.Because its core components are compressors, it is much more expensive than semiconductor refrigerators.

On the other hand, compared to the real and durable warm and warm box, the compressor refrigerator is relatively "delicate". Although some products claim that its compressor can work normally under 45 , we also need to pay attention to daily use in daily use.Avoid accidents such as bumps and flipping.

Having said so much, many people may ask why some cold and warm box claims to reach the refrigeration capacity of below zero X , but it is far from the actual use?Because some people ignore a factor, that is the ambient temperature.Especially for the cold and warm box, the cooling results of the ambient temperature at 50 C and 25 C are very different. If the refrigeration capacity of 20 C, the final refrigeration result of the two will be as much as 25 C.

Comparison

The price of the "warm and warm box" is basically below 1,000 yuan, but the cooling effect can only reach the point of cooling, suitable for some areas with low requirements and low environmental temperature.Lost meaning;

Compressor vehicles carry refrigerator: The price is basically above 2,000 yuan, but the cooling effect is good, it can freeze, there is no problem with ice cream, ice cream at all, and even drink iced (iced) drinksIn high areas, even if the ambient temperature exceeds 37-38 degrees, or even more than 40 degrees, the temperature can still reach -10 degrees when it is filled with things.

Pay attention to the use of car refrigerators

Select the right capacity according to actual needs

Do not cover the body's heat dissipation holes to avoid affecting its heat dissipation ability

Do not store magnetic objects in the warm and warm box, so as not to affect the effect of refrigeration chip

Need to clean the inside of the refrigerator regularly to avoid bacterial breeding

When switching from refrigeration to heating, you need to wait for the internal recovery of the ambient temperature

Try to choose products with low voltage protection (battery protection) function when buying

If 24V power supply is not supported, you need to buy antihypertensive equipment (24V to 12V)

It is best to pull out the refrigerator power supply when stopping

When using a compressor refrigerator, fix it in the car, avoid inverted and obliquely.

Do not put carbonated drinks and beer for a long time in the frozen area of the compressor refrigerator, which is dangerous to explosion.
