Production method of plant straws and chopsticks

Abstract

The invention discloses a production method of plant straws and chopsticks. The production method comprises the following steps that cereals and straws are ground and then mixed, the cereal powder and the straw powder are ground and mixed with any one or more of tubers, vegetables and fruits, the mixture is added into an extruder with the die orifice diameter smaller than 50 mm to be subjected to primary extrusion curing, a plant mixture is extruded from an outlet of a secondary extruder to be cured into a hollow pipe or a solid pipe. The invention relates to the technical field of straw and chopstick processing, plant straws and chopsticks are researched and produced through a deep processing technology of the cereals, the straws, the tubers and the vegetables and fruits, the utilization value of the cereals, the straws, the tubers and the vegetables and fruits is improved, the prepared plant straws and chopsticks have natural colors and tastes after the cereals, the straws, the tubers and the vegetables and fruits are cured, the prepared plant straws and chopsticks have the use functions of plastic straws and chopsticks, and overcome the defect that the straws and chopsticks made of plastics are non-degradable, the machining process is high in mechanization degree, the raw material utilization rate is high, the cost is low, and the environment pollution is avoided.

Description

technical field [0001] The invention relates to the technical field of straw and chopsticks processing, in particular to a method for producing plant straws and chopsticks. Background technique [0002] Straw, also known as drinking straw, is a cylindrical, hollow plastic product. Its main function is to drink beverages in cups. For a long time, people have used plastic straws to drink milk, yogurt, soybean milk, pearl milk tea juice, oral liquid, etc. Serious environmental pollution and waste of resources due to non-degradable plastic straws; [0003] Disposable chopsticks refer to chopsticks that are discarded after being used once, also known as "convenient chopsticks". Disposable chopsticks are the product of fast-paced social life. Disposable wooden chopsticks have caused a lot of forest land to be destroyed, and inferior wooden chopsticks are not clean. [0004] Chinese patent CN108976731A discloses a preparation method of polylactic acid transparent straw, first PLA ...

Problems solved by technology

[0004] Chinese patent CN108976731A discloses a preparation method of polylactic acid transparent straw, first PLA is added in the twin-screw extruder, then PEO and EBS are added into the twin-screw extruder from the side feeding port, extruded, drawn strips, cooled, dried, and sliced ​​to obtain a modified PLA straw special resin. The polylactic acid straw has the characteristics of degradability and anti-pollution, but the preparation cost of the polylactic acid straw is relatively high, and its price is about 5-6 yuan of ordinary plastic straws. Times, not conducive to mass production;

[0005] Chinese patent CN109280225A discloses a method for preparing starch chopsticks. Mix corn and water in a mass ratio of 1:1 and ferment for 40 days to obtain amylase; mix corn and water in a mass ratio of 1:2 and ferment for 6-8 days to obtain Fermented product; however, the preparation process of the starch chopsticks is complex, the required fermentation time is long, the equipment investment is large, the production cost is high, and the process will produce pollution during the fermentation process, which is not conducive to industrial production;
