Reviewer 2 Report

The paper provides a comprehensive overview of the development and evaluation of cow dung composting equipment with ventilation heating. The current methodology provides a detailed description of the methodology used to develop and evaluate the composting equipment. Include information about the materials and equipment used, the specific procedures followed, and any relevant parameters or measurements taken during the experiments. The results in a clear and concise manner, accompanied by appropriate data analysis. The topic is of interest for researchers working in this field, and it is well written. But still some points need attention as pointed out to the authors for the improvement of this paper.

1.     The abstract may be rewrite without using abbreviation PLCs and MCGS. Also, in the bottom portion of the abstract include some specific assessment terms like of high-temperature duration, water content, pH, and Germination Index value etc.

2.     Authors are suggested to remove the section 4 and content of first paragraph should be incorporated in the introduction section. And second paragraph of current section 4 may be utilized in the section 3(Results and analysis) and Section 5 (conclusion).

3.     Based on second suggestion improve the introduction section and conclusion section.

4.     Reference used in the bottom of this paper is not appropriate in too many places.  For example, ref no.1,5,6 7, 8, 9 14, 15 etc authors should not used et. al. It is suggested to check throughout every reference and adopt some standard refencing style and make all the refences uniform as single adopted standard referencing style.

Reviewer 4 Report

This study presents the development and evaluation of cow dung composting equipment with ventilation heating. This equipment integrates aeration and heating devices, optimizing the operation of the control system linkage in the composting aeration and heating process to significantly enhance the efficiency of livestock  manure composting and produce high-quality organic fertilizer. Some comments were raised. 

Line 16: Avoid using abbreviations in “Abstract” such as PLC and MCGS. The abbreviations must be written in full (with the corresponding abbreviations in bracket).

Line 21: Please specify in the abstract the evaluated parameters.

Abstract: Some important results (findings)0 should be presented at the end of the Abstract.

The fifth keyword (“Assessment”) is not appropriate and should be reconsidered.

Line 26 and 27: What is mu?

Line 77: What is the material of construction for the fermentation tank?

Line 81-82: What are the proposed dimensions of the fermentation tank of cow dung composting? Please state clearly.

Line 113: “Cow dung composting is a relatively static and oxygen consuming process”. Is there any inlet for oxygen gas to the fermentation tank? Please explain.

Line 363:380: Discussion of the reported results ad comparisons with other experimental data found in the literature should be integrated in these sections.

Is this overall proposed equipment for cow dung composting economic?
