Preventing Caking, Degradation, and Contamination in Agro Manufacturing


The Industry Challenge

Fertilizers, pesticides, herbicides, and agro-based products are inherently hygroscopic. Moisture absorption during manufacturing, storage, and packaging causes caking and solidification, reduces product efficacy, triggers chemical reactions between ingredients, creates safety hazards, and results in regulatory non-compliance with export and domestic quality standards. Drystar India Pvt. Ltd. provides industrial desiccant dehumidification systems that protect agro product quality from manufacturing through to final distribution.

Key Challenges & Why Change Is Necessary


Understanding the challenges that make a smarter, more reliable solution essential.

Caking and Granule Agglomeration

Urea, ammonium nitrate, potassium chloride, and similar fertilizer granules are highly hygroscopic. Exposure to humid air causes granules to absorb moisture, agglomerate, and solidify in storage bags and bulk warehouses, making products unusable and triggering massive return

Pesticide & Herbicide Degradation

Active ingredients in pesticide formulations degrade rapidly in the presence of moisture, reducing field efficacy and potentially creating toxic breakdown products that pose safety and regulatory compliance risks.

Packaging Failures

Moisture-contaminated fertilizer and agrochemical products cause packaging to fail through chemical attack on liners, pressure build-up from gas evolution, and physical deformation of product granules resulting in supply chain damage and retailer complaints.

Processing Equipment Blockages

Hygroscopic materials block conveying, mixing, and filling equipment when they absorb ambient moisture during processing. This causes production stoppages, costly cleaning, and equipment wear.

Regulatory and Export Non-Compliance

FCO standards for fertilizers and CIB & RC regulations for pesticides require products to meet specifications at the point of use. Moisture-related quality failures lead to product rejections at the point of export inspection and domestic market surveillance.

The Industry Challenge

Fertiliser granules absorb moisture rapidly, causing caking and clumping that make packaging and field application impossible. Stored seeds lose germination rates and shelf life when exposed to uncontrolled humidity. Precise moisture control from storage through dispatch is essential for product quality and profitability.

Industrial AHU Cum Desiccant Dehumidifier (DIPL Series)


Product Overview

The Drystar DIPL Series is the primary solution for large fertilizer blending plants, agrochemical formulation facilities, and bulk agro product warehouses. It provides continuous, facility-scale humidity control that keeps processing and storage environments below the critical moisture thresholds at which product degradation begins.

Key Features

  • Process air: 1,000 to 6,000 CFM
  • Maintains target RH below 40%   critical threshold for fertilizer caking prevention
  • Compatible with existing building HVAC for seamless integration
  • Energy recovery options to minimise operational power costs in continuous operation
  • Handles high latent heat loads in tropical manufacturing environments
  • CE, ISO 9001:2015, ISO 14001:2015 certified
  • Full lifecycle support, including AMC contracts

How It Suits This Industry

Fertilizer and agrochemical manufacturing facilities operate year-round in India's most humid regions. The DIPL Series is engineered to maintain stable, low-humidity conditions through the Indian monsoon season the most critical period for product quality protection in this industry.

Why This Is the Best Choice

Drystar's energy-efficient design means that the cost of operating the DIPL Series in a fertilizer plant is a small fraction of the losses prevented by eliminating caking, degradation, and product recalls. The system delivers measurable, positive ROI within a single production season.

Heavy Duty Industrial AHU Cum Dehumidifier (DIPL-8000 to DIPL-15000)


Product Overview

Large fertilizer complexes, NPK blending facilities, and agro product bulk warehouses require powerful dehumidification across very large enclosed spaces. The Drystar Heavy Duty DIPL Series provides 8,000 to 15,000 CFM of process air capacity, ensuring comprehensive humidity control even in the largest facilities.

Key Features

  • Process air capacity: 8,000 to 15,000 CFM
  • Handles enormous latent moisture loads from bulk hygroscopic products
  • 24/7 continuous automated operation with remote monitoring
  • Heavy-duty construction for long service life in industrial environments
  • Scalable; multiple units can serve multi-hall warehouse complexes
  • Reduces humidity-related product loss, improving net plant yield
  • AMC support ensures continuous system availability through peak harvest seasons

How It Suits This Industry

Bulk fertilizer and seed storage warehouses handling tens of thousands of tonnes of hygroscopic products require powerful, uninterrupted dehumidification. The Heavy Duty DIPL Series provides this at the required scale, protecting enormous product inventories throughout India's humid seasons.

Why This Is the Best Choice

For India's largest fertilizer manufacturers and cooperative agro warehouses, the Heavy Duty DIPL Series is the only domestically manufactured system with the capacity and proven reliability to protect national-scale product inventories. Drystar's nationwide service network ensures continuous support.
