How to keep fresh for Rice

China is a big agricultural country. Rice is rich in nutrition and is one of the main food for our people.

Rice is white rice after losing glume and seed coat through rice processing. Endosperm is sensitive to temperature and humidity because of its direct contact with air. It has strong hygroscopicity and a large amount of bacteria. Under the condition of high temperature and high humidity, rice has high respiratory intensity and is easy to heat. When the moisture content of rice exceeds the safety standard, the situation of fever is very easy to occur. Therefore, the storage and packaging of rice is very important!

Now the common rice packaging is sealed bag packaging, its advantage is that the number of bagged rice is more, the disadvantage is that the storage time is not long after opening!

A new kind of packaging is introduced: Canned Rice in cans, which is exquisite in package, beautiful in appearance and small in size, and has a sharp increase in appetite. It is especially suitable for those who work and live alone, which means they are not afraid of waste and worry.

Automatic vacuum nitrogen filling sealing machine is used to seal the cans. The air is pumped out first and then sealed to make the rice fresh-keeping time longer. The pressure resistance of the product is enhanced, with the functions of gas barrier, fresh-keeping, moisture-proof, anti-corrosion and anti-oxidation.

In the food processing industry, vacuum nitrogen filled packaging has a wide range of applications, such as chicken legs, canned fish, beef jerky, etc.; pickled products such as various pickles, bean products, preserved fruits and other foods that need to be kept fresh are increasingly sealed by vacuum packaging. After vacuum packaging of food preservation period is long, greatly extending the shelf life of food.

Vacuum nitrogen filling can sealing packaging machine and liquid nitrogen filling can sealing filling machine keep fresh and have good quality

Nowadays, there are more and more rice packed in small vacuum packages and cans. Although this kind of small package high-end rice price is relatively high, but there is no lack of sales, mainly by the 80s, 90s and other young consumers. According to the introduction, two kinds of packaging technologies can be used for rice packaging in cans:

1. Vacuum nitrogen filling packaging technology: the air in the rice can is extracted, nitrogen is filled after reaching the predetermined vacuum degree, and then sealed;

2. The rice can is filled with liquid nitrogen and mixed gas directly to force out excess oxygen, and then sealed

Here is a brief introduction to the differences between the two technologies

Guangzhou Utrust Packaging Equipment Co.,Ltd technicians introduced that the first method is to pack rice in cans, which can be packed and sealed by vacuum nitrogen filling packaging machine, which can balance the internal and external pressure difference, the air is pumped away, and then filled with nitrogen, which not only plays the role of anti-oxidation, moisture-proof, moth proof and mildew proof, but also greatly extends the fresh-keeping period of rice. More importantly, due to the obvious advantages of oxygen resistance and compression resistance, the rice can maintain its original color, aroma, taste, shape and nutritional components for a long time, and ensure the flavor, taste and quality of rice.

The second method is that after the rice is filled into the can, the liquid nitrogen is quickly filled into the can through the liquid nitrogen filling inlet. After other excess air is forced out, it enters the can sealing machine for sealing. The same as vacuum sealing packaging, this method can also lock fresh immediately, prevent rice oxidation, extend the rice preservation period, and ensure the nutrition and taste. Moreover, the production efficiency of this method is relatively high.

The rice can be filled automatically, continuously and rapidly through the filling machine, which can reduce the pollution caused by manual packaging. Moreover, the rice filling machine is made of non-toxic and durable 304 stainless steel, and the electrical and pneumatic systems adopt imported components, so the overall equipment failure rate is low, the reliability is high and the stability is good.

With the upgrading of consumption, small package rice is more and more popular with many consumers, and it may become the market development trend in the future. The rice packed in cans is conducive to immediate purchase and consumption, avoiding unnecessary waste. Moreover, the rice packaged in cans is convenient for storage, transportation and preservation, which greatly extends the shelf life and makes consumers eat more safely and at ease!
