The company developed hot air drying instant noodles

Japanese instant noodles manufacturers are currently working on the development of instant noodles that use air drying. Instant noodles were first introduced in Japan and have now become one of the convenient foods in the world. So far, instant noodles have been fried, but the oil heat easily destroys the texture of the noodle and loses the original flavor and texture of the noodles. Japanese instant noodles manufacturers are currently working on the development of instant noodles that use hot air drying instead of frying. The advantage of air-dried instant noodles is that there are not a lot of bubbles left after the frying, so the original flavor and texture of the noodles can be kept relatively high, and the contained calories are relatively low, which is beneficial to weight-loss bodybuilding. However, the disadvantage of air-dried instant noodles is time-consuming and the production efficiency is relatively low. At present, various manufacturers are trying to overcome these problems.

PVC pipe and pipe fitting

PVC pipe is extruded by hot pressing method after the cooperation of PVC resin, stabilizer and lubricant. It is the earliest plastic pipe developed and applied.

PVC-U pipe has strong corrosion resistance, easy adhesion, low price and hard texture. However, due to the leakage of PVC-U monomer and additives, it is only suitable for water supply system with transmission temperature not exceeding 45 ℃. Plastic pipes are used for drainage, wastewater, chemicals, heating and cooling fluids, food, ultra pure liquids, mud, gas, compressed air and vacuum system applications.

PVC pipe fittings include direct connection, tee and cross joint, and the tee is divided into 45 degrees and 90 degrees.

Advantages of PVC pipe

1. It has good tensile and compressive strength, but its flexibility is not as good as other plastic pipes.

2. Small fluid resistance: the pipe wall of PVC-U pipe is very smooth and has little resistance to fluid. Its roughness coefficient is only 0.009. Its water transmission capacity can be 20% higher than that of cast iron pipe with the same pipe diameter and 40% higher than that of concrete pipe.

3. Excellent corrosion resistance and drug resistance: PVC-U pipe has excellent acid, alkali and corrosion resistance, is not affected by moisture and soil pH, and does not need any anti-corrosion treatment during pipe laying.

4. Good water tightness: the installation of PVC-U pipe has good water tightness whether it is connected by bonding or rubber ring.

5. Anti bite: PVC-U pipe is not a nutrient source, so it will not be eroded by rodents. According to the experiment conducted by the National Health Foundation in Michigan, mice will not bite PVC-U pipes.

6. Performance test: curing time shrinkage splitting strength tensile property peel strength thermal stability application period storage period release of harmful substances.
