In fast food restaurants and beverage shops, plastic straws are commonly used by shopkeepers. This is also a kind of plastic pollution. In order to solve this situation, many people in society have begun to diverge their thinking and create new things to replace plastic straws. Fast food chains such as Starbucks and McDonald's went to pilot projects, and edible straws became a hot spot for research and development.
The rice straw is made of rice and tapioca (cassava is the raw material for making pearls in bubble milk tea, which can make the straw strong and tough, and the surface is smoother). It is made by a puffing extrusion process. Its appearance is no different from ordinary plastic straws. The surface of rice straws is smooth, strong and flexible. Compared with ordinary plastic straws, rice straws can be eaten directly, and the taste is crispy and crispy, and the taste is like the common rice croissant. The raw materials can also be adjusted to make straws with different colors. The rice straw made by the puffing extrusion process can be soaked in hot drinks for 2 to 3 hours, while in cold drinks it can last longer, up to 5 to 10 hours. Moreover, the rice straw is completely degradable and more eco-friendly. It can be used as a substitute for plastic straws and will not pollute the environment like plastic straws, and it also meets the requirements of many countries' laws and regulations.
Drying is a very critical link in the production process of rice straws. The air-energy heat pump dryer can control the temperature and humidity to ensure that the straws are evenly dried, so that the straws are not easily deformed during the drying process.
The rice straw dryer is a device developed and produced on the basis of air energy heat pump technology. The rice straw dryer can absorb a large amount of heat from the air with a small amount of electricity. After a series of conversions, the heat can be The hot air is delivered to the straw drying room to increase the temperature in the drying room to the temperature required for the straw drying. At the same time, the humidity in the straw drying room is automatically controlled through a computer program to remove the moisture evaporated from the straw. The intelligent temperature and humidity control system can ensure the drying quality of the straw. The straw drying equipment uses electricity to operate, clean and environmentally friendly, will not pollute the environment, and consumes little electricity. Under standard conditions, the heat generated by the drying equipment for one kilowatt is equivalent to the heat generated by the pure electric heating equipment. Very efficient and energy-saving.
With the implementation of environmental protection policies, environmental protection straws will gradually replace plastic straws and enter people's daily lives. At the same time, it will also promote the vigorous development of the environmental protection straw industry, such as rice straws, corn starch straws, paper straws and other production equipment.
