Numerical Simulation on Flow in Self-stacking Spiral Freezer
摘要
Abstract
The purpose of reducing the energy consumption and improving the freezing efficiency are achieved by improving the structure and changing the parameters of frozen food to increase the average velocity of the flow field under the condition of constant fan power.Establish two-dimensional turbulence model and adopt SIMPLE algorithm to analyze flow of the original structure without frozen,the flow field with holes and baffles,the flow field of food placed in different density and .The results show that the influence of mesh belt on the average velocity of flow field in the spiral tower is small,a baffle plate and opening holes are beneficial to improve the average velocity of airflow and increase sufficient of heat exchange,considering the increase of the density of frozen products,the average velocity,pressure and fan power should be taken into account and that increasing the height can increase the average velocity of airflow under the condition that frozen height should not be higher than the height of the hole .关键词
