Claims (2)

------August 31, 2017------(OCR) Page 1 of 1 page. Claims: 1. Chopsticks made from rice flour mixed with coconut fiber have the following raw material composition: • Rice flour 59.5-63.0% by weight • Coconut fiber 7.0-10.5% by weight • Add water to make the composition 100% by weight. 2. The manufacturing process of chopsticks from rice flour mixed with coconut fiber involves the following steps: a. Prepare the raw materials by mixing the rice flour with the coconut fiber according to the formula in point 1. Mix thoroughly by hand or with a mixer until the coconut fiber is evenly distributed in the rice flour. b. Add the water according to the formula in point 1 to the mixture from step a using a spraying method and mix thoroughly by hand or with a mixer, ensuring even distribution of the water. c. Then, shape the chopsticks. The mixture obtained from step B is shaped using a single-screw extruder. The machine's operating conditions are set as follows: Length-to-diameter ratio (L/D ratio) of 20:1, flange opening size of 6 mm, feeding rate of 5 kg/hour, screw speed of 50 rpm, feed zone temperature of 30°C, compression zone temperature of 30°C, melting zone temperature of 45°C, die opening temperature of 75°C, and the internal pressure of the screw barrel is controlled to equal the external atmospheric pressure. Once the product flows out of the flange opening, it is cut to the desired length of 20-25 centimeters using a knife. Finally, the product from step D is dried in a hot air oven at 50-55°C for 6 hours to obtain chopsticks made from rice flour mixed with coconut fiber. 1. Chopsticks made from rice flour and coconut fiber have the following ingredients: • Rice flour 59.5-63.0% by weight • Coconut fiber 7.0-10.5% by weight • Add water to make the total composition 100% by weight. 2. The process of manufacturing chopsticks from rice flour mixed with coconut fiber involves the following steps: a.

Add water according to the formula in step 1 to the mixture from step a using a spraying method and mix thoroughly by hand or with a mixer, ensuring even distribution of the water. c. Shape the chopsticks: Shape the mixture from step b using a single-screw extruder. The machine settings and operating conditions are as follows: Length-to-diameter ratio (L/D ratio) of 20:1, flange opening size of 6 mm, feeding rate of 5 kg/hour, screw speed of 50 rpm, feed zone temperature of 30°C, compression zone temperature of 30°C, melting zone temperature of 45°C, die opening temperature of 75°C, and maintain the internal pressure of the screw barrel equal to the external atmospheric pressure. d. When the product flows out of the flange opening... C. Cut the product into desired lengths of 20-25 centimeters using a knife. D. Dry the product by drying it in a hot air oven at 50-55 degrees Celsius for 6 hours. This will yield chopsticks made from rice flour mixed with coconut fiber.
