IQF Frozen Long Green Bean

The manufacturing process of IQF Frozen Long Green Bean is advanced and complex, aiming to maintain the freshness and nutritional value of beans to the greatest extent.

The option of raw materials is essential. Fresh, tender, fiber-free, brilliant eco-friendly, pest-free, spot-free, and uniformly lengthy beans are called for. The perfect length is 15-20 cm, which lays the foundation for quality in subsequent handling.

In the cleansing process, the beans are consistently rinsed with a big amount of running water to remove surface area dust, dust, and feasible residual chemical contaminations. If needed, they can be soaked for a short time to help in getting rid of stubborn discolorations, and afterwards drained completely to guarantee the tidiness of the raw materials.

The cutting process is performed according to product requirements. The majority of them retain the whole origin form. If there are specific specs, they can be cut into 5-10 cm sectors. When reducing, make sure that the cuts are neat and the size is exact, which is conducive to consistent home heating during the quick cold process.

The blanching procedure is optional but crucial.

The entire bean takes around 10-15 minutes to freeze, and the cut section takes 8-12 minutes. Ultimately, it is product packaging and storage.

After fast cold, it is promptly packaged with moisture-proof and oxygen-proof plastic film. Vacuum cleaner packaging is much better. It is put in a cold storage below -18 ℃. The temperature and humidity are inspected on a regular basis to ensure exceptional high quality within the service life of 12-24 months.
