Grain Storage and Drying: How to Store Properly to Sell Better

The storage and drying of grains is the most strategic and most neglected link of the entire Brazilian agribusiness chain. The producer who harvests and delivers immediately to the cooperative or intermediary receives the worst price of the crop — and loses 15 to 40% of their income potential simply for not having the infrastructure to store and wait for the right moment to sell.

Brazil loses between R$ 10 and R$ 15 billion per year in post-harvest grain losses — mainly due to inadequate storage, lack of proper drying and an excess of grain offered to the market at the same time. The national static storage capacity is still more than 30% lower than production — creating a logistical bottleneck and chronic economic loss for the family farmer.

When the storage system is strengthened with monitoring technology and access to credit for on-farm (on the property) structures, it significantly improves operational efficiency, profitability and the autonomy of the rural producer. This combination allows the farmer not to depend exclusively on third-party warehouses, reducing logistical costs and losses in grain quality. This segment can contribute greatly to job and income generation in Brazil.

Join our strategic actions for implementing the best solutions in the Brazilian agricultural sector. Our activities, studies and advanced research cover 20 chains and the 255 segments of the national agro — from the grain chain to sustainable extractivism, including horticulture, fruit growing, livestock and much more.

The series Inovação Para o Brasil Produzir Mais was developed precisely to identify and implement the best solutions available in Brazil and worldwide, across the 255 segments of the agricultural sector — with accessible technical language, up-to-date data and a focus on practical results for producers, suppliers, governments and traders.

1. Opportunities for Small Rural Producers

How to structure on-farm storage to sell in the best price window

The rule is simple: who stores, sells when they want. And who sells when they want, sells at the best price. The price difference between harvest and offseason can range from 20 to 50% for soybeans, corn and beans — and this is the direct return on investment in storage.

✔ Silo bag (bolsa de polietileno) — temporary low-cost storage (R$ 1.200 to R$ 2.500 per 200 ton bag)

✔ Flat-bottom metal graneleiro — permanent solution for 100 to 5,000 toneladas

✔ Grain dryer — essential for corn harvested above 20% moisture; prerequisite for safe storage

✔ Thermometry and aeration — temperature and humidity control that prevents molds and insects

✔ PRONAF Mais Alimentos and ABC+ for financing of on-farm dryers and graneleiros

The E-Book 01 — Strategic Manual for the Small Rural Producer presents, in detail, the best solutions for this segment and the other 254 of Brazilian agro — focusing on method, cost reduction and progressive growth from Agro 1.0 to Agro 6.0. Access now for R$ 50 →

2. Opportunities for Micro and Small Local Suppliers

Which equipment and services the storage chain demands continuously

The demand for storage equipment and services is permanent and growing in Brazil's interior — especially for the supplier who serves the small producer with small- and medium-scale solutions, more accessible than the industrial systems of the large cooperatives.

Solutions by area of engineering applied to the segment

Our activities, studies and advanced research cover six major areas of engineering — and the chain demands solutions in all of them:

Electrical Engineering and Computing — control panels for dryers, automation of aeration systems and remote monitoring of silos;

Electronic Engineering and IoT — temperature and humidity sensors for silo thermometry; real-time mobile alerts;

Control and Automation Engineering — automatic controllers for aeration, ventilation and drying cycles;

Mechatronics and Robotics Engineering — grain conveyors, bucket elevators and internal handling systems;

Renewable Energy Engineering — solar power to run dryers and aeration systems; the farm's largest energy consumer;

Data Science and Artificial Intelligence — predictive models of grain quality, deterioration alerts and integrated commercialization platforms.

✔ Installation and maintenance of grain dryers — high-urgency service during harvest; preventive maintenance year-round

✔ IoT systems for silo monitoring — temperature, humidity and CO₂ in real time; payback in one season with saved grain

✔ Solar power for dryers and aeration motors — 40 to 70% reduction in drying costs

✔ Installation of silo bag and graneleiros — high-demand field service in the post-harvest

✔ Technical assistance in storage management — training for operators of family silos

3. Opportunities for Municipal Governments

How the municipality can structure community storage and reduce post-harvest losses

The lack of storage is the main economic vulnerability factor for the small producer — forcing them to sell at harvest, when the price is always lower, instead of waiting for the offseason. Municipalities that invest in community storage create one of the most efficient public policies for increasing rural income.

✔ Implementation of a municipal community warehouse — 500 to 2,000 ton silo for collective use by small producers

✔ Subsidized community drying program — access to drying service for producers without their own equipment

✔ Municipal credit for individual silo bag — the lowest-cost solution for the small producer

✔ Partnership with cooperatives for management of community storage and joint commercialization

✔ Municipal IDM: storage capacity per capita as an indicator of the efficiency of the local productive chain

The E-Book 03 — Reference Guide for Municipal Governments presents the step-by-step for secretaries and municipal managers to implement effective public policies for the 255 segments of agro. Access now for R$ 450 →

4. Opportunities for Small Agricultural Product Merchants

How providing storage services generates recurring business in Brazil's interior

The provider of storage services has one of the most predictable and recurring demands in agribusiness: every harvest, the producer needs to dry, clean, treat and store. The service provider who offers a complete package — drying, monitoring and exit logistics — creates a long-term relationship with guaranteed annual value.

The model of storage as a service — where the supplier installs the silo, monitors quality and manages grain outflow — is a recurring revenue business model that is growing rapidly in the interior of the Cerrado and the South. The producer pays for the service; the supplier earns from efficiency and technology.

Products with high commercial potential

The main products derived from this segment for local retail and foodservice:

Grain drying service by tonnage— recurring B2B model; R$ 5 to R$ 15/ton; demand concentrated in the harvest;

Remote silo monitoring by IoT— monthly service; R$ 200 to R$ 500/silo; high customer retention;

Silo bag rental and installation— low-investment, high-turnover field service;

Storage management consulting— high-value technical service; reduces losses and increases grain value;

Sale and installation of graneleiros and silos— high-ticket product; financing through BNDES Finame;

Laboratory analysis of stored grains— quality service for cooperatives and exporters.

Merchant profiles and their specific opportunities

✔ Agricultural service providers: drying and storage by tonnage — guaranteed recurring revenue every season

✔ Agro stores: silo bag, silo thermometers and humidity sensors — high post-harvest demand products

✔ Equipment distributors: graneleiros, dryers and aeration systems — high-ticket product with financing

✔ Service cooperatives: collective storage and marketing management — high social impact business model

✔ Digital platforms: commercialization platform integrated with the silo — high-value AgTech product

✔ Technical consultants: quality management of stored grains — niche service with high remuneration

Growth strategies for the local merchant

The storage business has two highly profitable models for the local entrepreneur: the service provider by tonnage (drying + monitoring) and the provider of complete solutions (silo installation + IoT + outflow management). Both have recurring revenue, growing demand and little qualified competition in Brazil's interior.

The BNDES Finame finances drying and storage equipment with terms of up to 60 months. The PRONAF Mais Alimentos finances on-farm silos for family farmers. The Pronampe finances the structuring of storage service companies.
