(4) Description of operation points

(1) Mango Pulping: Pick eight ripe fresh mangoes, rinse them with running water, pour them into hot water at 85-100 °C, and blan them for 0.5 to 2 minutes. The pulp after peeling the nucleus is first placed in a beater for beating, and then finely ground with a colloid.

(4) Homogenization and degassing: The mixed liquid is homogenized under the high pressure of 19 MPa, which makes the structure more uniform and viscous. The homogenized liquid is off at 40-50 ° C and 80-90 kPa. gas.

(5) Filling, sealing, sterilization: degassed semi-finished products and fashion bottle seals, sterilized at 90-95 ° C for 30 minutes, and then cooled to room temperature with cold water.
