Description

technical field [0001] The patent of the invention belongs to the field of solid-state fermentation engineering control, and relates to a solid-state fermentation mass transfer and heat transfer numerical analysis system based on numerical simulation and a solid-state fermentation substrate physical property parameter system, which are used to calculate the charging size of the solid-state fermentation substrate and optimize the solid-state fermentation substrate Loading method. Background technique [0002] In today's society where the crises of resources, environment and energy are intensifying, solid-state fermentation has many advantages, such as low pollution, energy saving, water saving, and high product yield, compared with the more polluting liquid fermentation, so it is more timely. However, solid-state fermentation is difficult to achieve industrialization, and it cannot replace liquid-state fermentation in a short period of time. The main factor restricting the in...

Problems solved by technology

However, previous reports usually only focus on the influence of one or a few matrix physical properties on a certain transmission process (for example, only study the influence of matrix porosity on its air permeability), ignoring the interaction between various factors , and also ignores the coupling phenomenon between various transfer processes, the research results are relatively one-sided, and cannot reflect the overall effect of the physical properties of the fermentation substrate on the mass-thermal coupling transfer process. Cooperate with the transfer process model to improve the operability and reliability of the numerical analysis platform

However, actual production still mainly relies on empirical design, and the above ideas and methods have not been reported yet.
