preparation example Construction
[0016] The preparation method of the slow-release type tea-containing plastic particles of the present invention has the following steps:
[0017] 1. Take each component according to the mass ratio of tea powder: binder: foaming agent: 10-40: 50-80: 5-10, wherein the tea powder is crushed from dry tea to Made of 200 mesh to 300 mesh, the binder is ethylene-vinyl acetate polymer material with a melting point below 100°C, and the foaming agent is inorganic foaming agent sodium bicarbonate.
[0018] 2. Fully stir the tea powder, binder and foaming agent evenly.
[0019] 3. Set the preheating temperature of the internal mixer to be 10°C higher than the melting point of the ethylene-vinyl acetate polymer material for preheating, and the mixed raw materials are fed into the internal mixer at a constant speed for refining for 5-10 minutes. After the adhesive is fully melted, set the molding shape and size of the screw extruder, extrude and cool to form.
Embodiment 1
[0021] Example 1: Take a certain amount of dried Tieguanyin tea leaves, crush them in a pulverizer, and sieve them to retain 200-mesh particles. Crushed Tieguanyin powder, EVA28-25 particles, foaming agent NaHCO 3 Mix evenly at a ratio of 10:80:10, add it to an internal mixer with a preheating temperature of 100°C, refine for 10 minutes, adjust the speed of the screw extruder to 40r / min, and set the diameter of the cylindrical shape to 2cm , extruded and cooled to form. Experiments have proved that the tea-containing plastic particles have the function of slowly releasing the active ingredients of green tea for a long time.
Embodiment 2
[0022] Example 2: Take a certain amount of Xinyang Maojian tea leaves, crush them in a pulverizer, and sieve them to retain particles between 300 meshes. Crushed Tieguanyin powder, POE8100 particles, foaming agent NaHCO 3 Mix evenly at a ratio of 40:50:10, add it to an internal mixer with a preheating temperature of 110°C, refine for 5 minutes, adjust the screw extruder speed to 30r / min, and set the diameter of the cylindrical shape to 2cm , extruded and cooled to form. Experiments have proved that the tea-containing plastic particles have the function of slowly releasing the active ingredients of green tea for a long time.
