A control method for a viscous semi-liquid frozen or hot food dispenser comprising a stirring means configured to stir the food, a motor (50) configured to drive the stirring means to rotate, a refrigerating means or heating means configured to input cold energy or heat energy into the food, a rotation speed sensor (80) configured to detect a stirring speed, and a temperature sensor (13) configured to detect the food temperature, the control method comprising the steps of: a) refrigerating or heating the food by the refrigerating means or heating means; b) comparing the food temperature detected by the temperature sensor (13) with a target preset value of the food temperature, and determining to continue the refrigeration or heating, or to stop the refrigeration or heating and to keep stopping for a preset time; c) intervening by corresponding adjustment of the target preset value when a data set collected from the rotation speed sensor (80) shows that change trend of the rotation speed meets predefined intervention conditions; and d) returning to step a) for the next cycle. The control method for a viscous semi-liquid food dispenser is capable of controlling viscosity of food accurately and reliably to maintain consistence of the characteristics of the dispensed product and minimize the influence from the environment as much as possible.
