Method, device and equipment for obtaining moisture ratio of agricultural product based on different drying stages

Abstract

The invention relates to an agricultural product moisture ratio obtaining method, device and equipment based on different drying stages, and belongs to the technical field of agricultural product drying. The method comprises the steps: carrying out drying experiments on target agricultural products under different preset drying working conditions, and obtaining experimental data; according to an existing common drying model, fitting experimental data, and selecting a relatively most suitable drying model; writing the fitting constants into function expressions of related working conditions; performing derivation processing on a moisture ratio expression in the selected model to obtain a drying dynamic derivative model; according to four slope expressions in a four-level four-order classical Runge-Kutta method, obtaining the drying rate in the sectional type drying process; and setting a proper time step length, and obtaining a moisture ratio corresponding to each time point by utilizing a recursive relational expression in a four-stage four-order classical Runge-Kutta method. The constant drying condition is not required to be limited, and the drying time and the moisture ratio at the condition conversion point are not required to be calculated, so that the technical problem that the condition change is difficult to calculate is solved.

Benefits of technology

This patented technology allows farmers to select their crops depending upon factors like weather or soil quality that affect them' ability to grow well (their nutritional content). By doing this, they are able to produce high-quality crop with fewer losses compared to traditional methods such as field trial plantings which require many trials before reaching maturity) while also improving overall yield potential by optimizing production strategies.

Problems solved by technology

This patented technical solution describes how changing the amount of water inside certain materials during production causes changes on these properties like density, viscosity, wettability, adhesion between layers, shape, size, texture, color, taste, smell, odor, and even chemical reactions affects the quality of crop product produced at any given stage. To address this issue, previous methods have been developed but they are limited when studying other aspects such as thermal conductivity, convection coefficients, gas diffusion rates, and pressure differences across multiple stages involved with the production cycle.
