Studying the Influence of Moisture Content in Grain on the Efficiency of the Microwave Field Transfer into a Grain Layer with the Use of a Computer Model

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The manuscript “Studying the influence of moisture content in grain on the efficiency of the microwave field transfer into a grain layer with the use of computer model” presents a detailed investigation into how varying moisture content in grain affects the distribution and efficiency of microwave energy transfer in a grain layer. The authors analysed the efficiency of the waveguide system as the moisture content varies. The study design is well done and documented; however, the manuscript can be improved. The topic is congruent with the Aims and Scope of Applied Science journal. 

Please try to improve the distinction between the sections. For example, the difference between “Results”, “Discussion” and “Material and Methods” can be improved. For example, in lines (L131-L134) “The antenna…them” which ideally should be part of the "Discussion" rather than the "Materials and Methods." 

Please, try to improve the quality of the Figures. For example, the “Φ” phi signal in Figure 5 seems to be copied and pasted from another source. The same text in Figure 8 is blurred.

Reviewer 2 Report

Comments and Suggestions for Authors

I have reviewed the manuscript and my recommendations are as follows:

1. The abstract provides a clear overview of the research objectives and methodology. However, it would be beneficial to include a brief statement about the significance of the findings or potential implications for practical applications.

2. The paragraph discussing the convective-microwave processing units could provide more specific details about the modular design and the functionality of the waveguides with slot radiators. Providing specifics on the design features and how they contribute to the uniformity of grain exposure to the microwave field would enhance understanding.

3. The authors correctly identify a research gap regarding the impact of moisture content variations on microwave field penetration and the operational matching between the waveguide structure and the magnetron system. However, it would be beneficial to clearly articulate the significance of addressing these gaps in terms of improving the efficiency and economic viability of convective-microwave processing units.

4. Ensure that all referenced sources are properly cited and relevant to the discussion. Additionally, consider citing recent studies to demonstrate the current state of the field.

5. It is recommended that the clarity of the images be improved. It is recommended that the formatting of the text in the images be consistent.

6. Suggesting potential avenues for future research based on the current findings would add depth to the conclusion. This could include exploring the effects of different grain types, optimizing microwave-active zone design parameters, or investigating the scalability of the proposed methods for industrial applications.

7. While the qualitative observation that wetter grain absorbs more microwave energy is insightful, incorporating quantitative analysis would strengthen the findings. Including data on the actual absorption rates or temperature changes of grain samples with different moisture content would provide a more comprehensive understanding of the relationship between moisture content and microwave energy absorption.

8. The manuscript briefly mentions the implications of these findings on microwave-active zone structures and operation algorithms of magnetrons and discharge units. Expanding on this discussion by providing practical recommendations or suggestions for optimizing microwave drying processes in agricultural settings would be valuable for readers interested in applying this research to real-world scenarios.

9. Consider conducting statistical analysis to assess the significance of observed differences in Q-factor values for various moisture content levels. This would strengthen the validity and reliability of the findings.

Comments and Suggestions for Authors

Dear Authors,

Your work on the convective-microwave method for grain processing is commendable. The design of your study is well-structured, allowing for a clear presentation of your findings. Your research is relevant to the advancement of technological units in grain processing, providing valuable insights into the convective-microwave method's efficacy.

While your study is exemplary, there are minor issues that should be addressed. These include:

-line 81 please define Q-factor
-line 103 I advise adding the specific dielectric constants for each of the mentioned percentages
-line 104/105 is there a reference for this?

-Figure 5 why is the moisture content 24% not shown?

-line 214 specify which figures

-lines 332/336 in italics?
