Flow curve. Definition of a flow curve. Typical rotational tests are viscosity functions that depend on shear rate, shear stress, time, or temperature. The results of a rotational test can be displayed on the one hand as a flow curve diagram showing the resulting shear stress values, and on the other hand as the corresponding viscosity function.
A method for predicting the difficulty of sucking a liquid food sucking pipe based on a rheological test
ActiveCN119476110BFlow propertiesMaterial strength using steady shearing forcesOrganoleptic evaluationConsistency index
The application provides a kind of liquid food straw sucking difficulty prediction method based on rheological test, the characteristic flow curve of liquid food sample is measured by steady flow test, respectively Carreau-Yasuda model or Casson model (if it is yield type fluid) fitting is carried out, and the predicted flow Q of straw is calculated c , then Herschel-Bulkley model fitting is carried out, and the consistency index K h , power law index n, Herschel-Bulkley yield stress τ h (if it is yield type fluid) is obtained.According to the equation of pipe flow flow, τ R Is calculated and substituted into Herschel-Bulkley model, and the apparent viscosity corresponding to shear rate is obtained, then the prediction model is constructed to predict the liquid food straw sucking difficulty, replace the traditional sensory evaluation method, and provide new ideas for food enterprise research and development decision.
