Description

TECHNICAL FIELD

[0001] The utility model belongs to straw production equipment technical field, concretely relates to a degradable straw drying device. BACKGROUND

[0002] At present, the traditional plastic straw of nearly 30000 tons is produced and used in China every year, about 460 billion, the recycling of these disposable straws is difficult, and the degradation time can be as long as 500 years, which causes great difficulty in environmental governance. In order to govern white pollution and create green water and green mountains, the National Development and Reform Commission and the Ministry of Ecology and Environment issued the opinion on further strengthening the management of plastic pollution, which stipulates that by the end of 2025, the catering industry nationwide will prohibit the use of non-degradable disposable plastic straws, and biodegradable straws will fully replace traditional straws, which is the inevitable need of green development.

[0003] Direct water cooling is a necessary link in the production process of straws. Traditional plastics have good hydrophobicity, and the surface of the straw is dry after water cooling, and no moisture is stored. After the straw is cut, it can be directly packaged. However, the main component of biodegradable straw is PLA and other components, which is a hydrophilic material. After the straw is cooled in water, a large amount of water will be stored on the surface. The current drying process of 'fan blowing + drying' generally uses a fan to blow directly, and then transports the semi-finished straw with moisture to a special device for heating and drying. There are problems of high production energy consumption, low production efficiency and inability to realize continuous production. And the straw needs to be cut to the appropriate length after drying. Most of the existing straw cutting devices can only be cut according to the length specified by the device, and the length cannot be adjusted according to the actual demand. The length of the cut straw is not convenient for subsequent production and manufacturing, thereby increasing the labor and improving the manufacturing cost. UTILITY MODEL CONTENTS
