Peat Granulation for Humic Acid Concentration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for deriving humic substances result in low concentrations and unstable humic acid suspensions, complicating their application as effective plant growth promoters due to low resistance and rapid disintegration.
Innovation Solution
The method involves preliminary and re-granulation of peat to achieve smaller granule sizes, followed by mechanical and chemical activation in an aqueous solution with alkali addition to enhance humic acid concentration and stability, using a processing line that includes granulation, curing, and mixing stages to produce a biologically active humic product with elevated humic substance content.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional fragmentation and blending methods are used with weight ratio 1:5, then the process is simple, but the concentration of humic substances is low and resistance is low
Solution Approach 1:
The patent applies preliminary granulation of peat before extraction to create a more compact structure that increases the concentration of humic substances during subsequent processing. The granulation step prepares the raw material in advance to achieve higher effective concentration without complicating the overall process flow
Solution Approach 2:
The patent changes the physical state and density parameters of peat through granulation and curing processes. By controlling moisture content during granulation and applying thermal curing, the peat structure is modified to increase humic substance concentration and stability in the final extract
2Ease of manufacture
If humic acid aqueous suspension is derived with 4-6% concentration, then the extraction process is straightforward, but the suspension is unstable and quickly disintegrates
Solution Approach 1:
The patent applies preliminary granulation and curing of peat before extraction to create a stable structural framework. This pre-treatment ensures that the humic substances are released in a stable form during extraction, preventing rapid disintegration of the suspension while maintaining process simplicity
Solution Approach 2:
The patent modifies the chemical and physical parameters of peat through controlled curing at specific temperatures and moisture contents. These parameter changes stabilize the humic substances, ensuring the extracted suspension maintains its concentration and does not quickly disintegrate
3Quantity of substance
If preliminary granulation with curing for 12 hours and re-granulation is applied, then humic acid concentration increases to 12-13%, but the process complexity increases
Solution Approach 1:
The patent segments the granulation process into two distinct stages: preliminary granulation with curing, followed by re-granulation. This segmentation allows each stage to be optimized for specific purposes - the first for structure formation and concentration, the second for final product refinement - achieving high humic acid concentration through systematic breakdown of the complex process into manageable steps
4Quantity of substance
If the granules are poured into aqueous solution with ratio 6:4, then a viscous fluid paste is formed, but the pouring and packaging becomes difficult
Solution Approach 1:
The patent optimizes the ratio parameters of granules to aqueous solution (6:4) to achieve the desired viscous fluid consistency. By carefully controlling this ratio parameter, the paste attains optimal viscosity for product quality while remaining workable for pouring and packaging operations

AI summary
The present invention is directed to peat processing and includes the usage of peat as the organic raw material. The peat is processed through preliminary granulation with further curing of the derived granules in closed tanks for cooling. The cooled granules are subjected to re-granulation. Then the hot granules derived from re-granulation emerge into an aqueous solution. The derived mixture is stirred until it turns into a homogeneous viscous fluid paste. The paste is supplemented with alkali until the pH reaches the value of 10-10.5. The final product results after cooling of the paste to ambient air temperature.
