The Plastic Ups Drive Housing is what we call a floppy drive, and it's called floppy disk drive. It's a device that reads a 3.5-inch or 5.25-inch floppy disk. The most commonly used today is the 3.5-inch floppy drive, which can read and write 1.44MB of 3.5-inch floppy disk. The 5.25-inch floppy disk has been phased out and is rarely seen.

Since 2013, sales of instant noodles in China have begun to decline. According to instant noodle dealers, the cost of a box of 24 bags of instant noodles is 2 yuan per pack. The price is 2.5 yuan per pack, and the cost is only a few cents. In the case of a decline in sales, products often do not make money or even lose money. In order to make up for the vacancy in the instant noodle market, a new type of instant noodles has emerged – the freeze-dried noodles.
The lyophilized surface is different from the ordinary instant noodles. It does not have the process of frying. Instead, the fresh noodles, soup and vegetables are frozen by vacuum freeze-drying technology, and then dehydrated and dried in a vacuum environment of minus 30 °C. It can be produced by a vacuum freeze dryer that combines a refrigeration system, a vacuum system, and a moisture removal system. Sublimation can remove moisture from frozen biological products. The process of freeze drying is called freeze drying. The lyophilized surface is like other instant noodles. Just re-add water to restore the original appearance, and the color, aroma and taste remain basically unchanged.
It is because the freeze-dried surface adopts vacuum freeze-drying technology, and the physicochemical structure of the food is not changed by high temperature, so its nutrients are not lost, and it is basically equal to fresh food. In addition, up to 95% of the dehydration rate makes the shelf life of the food greatly extended, and can be stored in a normal temperature environment for more than five years without destroying the packaging. It is understood that this healthy lyophilized noodle has become an instant noodle that can be sold on motor trains in May 2017.
It can be seen that vacuum freeze-drying technology can not only maintain the freshness and nutrition of food, but also prolong the shelf life of food. In addition to freeze-dried noodles, other products are included in the freeze-dried food sector:
Freeze-dried fruit, which is a relatively common food. Commonly used are freeze-dried red dates, pineapples, mangoes, durians, etc. Freeze-dried pet foods and freeze-dried pet foods are called high-end products in foreign countries. They are scarce in China and are now There are pet companies to introduce freeze-dried raw meat and freeze-dried dog food; freeze-dried cold-collected instant coffee, cold-collected coffee was first launched by Starbucks, and has been popular in the domestic market in the past two years, and has become the main force of summer coffee revenue; Dry food, a Fujian company launched probiotic yoghurt soluble beans, online sales exceeded 100,000, welcomed by consumers, children's health food is a more demanding product direction, more focused and more subdivided. Freeze-dried foods for children include milk beans, molar snacks, and the like.
Although many domestic enterprises have introduced a variety of freeze-dried foods, the market size and development speed of China's freeze-dried food industry lags behind that of foreign countries. This is related to the following aspects. First, we can see from the above product analysis that lyophilization Technology is a relatively high-end food production process, product prices are difficult to meet the consumption level of ordinary consumers; Second, China's freeze-dried foods produce more fruit and vegetable products for export, focus on foreign markets, less investment in the development of the domestic market; Consumers are not used to the taste of certain freeze-dried foods.
From the analysis of the reasons, it can be seen that the development limitation of the freeze-dried food industry is not the backwardness of technology, because many enterprises in China have developed vacuum freeze dryers to produce freeze-dried fruits and vegetables for export abroad. The difficulty lies in the development of the domestic market. The freeze-dried food market cannot yet become a popular market. Whether it is a new company that has entered the field for the first time or a mature company, the entry point must start with product characteristics and product demand, as well as product innovation, branding and marketing. .
Floppy drive device built - in and external two. The built-in floppy drive USES the special FDD interface, while the external floppy drive is generally used for the laptop, using the USB interface.
With the development of computer, these disadvantages are gradually obvious: too small capacity, slow reading and writing speed, poor service life and reliability of floppy disk, and easy loss of data, so floppy drive has been replaced by other devices. New computers are no longer equipped with floppy drives, and personal computer users are no longer equipped with floppy drives.

When it comes to "fast noodles", many people think of instant noodles, which used to be the savior of our late night hunger. However, as consumers' demands for dietary health gradually increase, instant noodles that are considered "fried, unhealthy" are difficult to get rid of the fate of being abandoned.
