Crop Cooling

Products

Bringing in the harvest is every grower’s ultimate aim and what a satisfying feeling it is when the combines are rolling, and the stores are filling. However, the final act of this crops journey from field to factory is not the harvest but the storage.  

Crops should exit the store in the same, if not improved, condition that they entered, and this is achieved by adequate and well-timed airflow and correct air distribution.

Bringing together equipment from manufacturers in Devon, Somerset, Lincolnshire and Suffolk Evans and Pearce is proud of the grain cooling systems we have brought to the market since 1968. No matter your preference for cooling grain this harvest, Evans and Pearce has systems to suit a range of situations. 

We have always believed in working with our suppliers as closely as we work with our customers; it is often suppliers that help us solve the sometimes complex problems we are presented with.

Made Great in Britain

Our fan range is all manufactured in Devon by a company we have worked with since 1978. We have sold these fans all over the world. The robust construction has seen them used in demanding situations for cooling grains, peanuts, woodchip, horse bedding and even road plainings. We even have several high volume fans, installed in 2018, working in New Zealand for cooling superphosphate fertiliser. 

Our Polycool ducting is manufactured in Lincolnshire. We developed Polycool in 1998, working alongside ADAS to trial the product and ensure the slotted area of our proposed new duct facilitated the airflow needed for successful crop cooling. From humble beginnings the new plastic products gained a reputation for longevity and strength. With sales of Polycool pedestals now well beyond 35,000 since its launch, the merits of this type of duct are beyond doubt.

CROP COOLING FAQs

When grain is harvested, it often retains residual heat and moisture, creating an environment where mould, pests, and harmful microbes can thrive. By cooling the grain, farmers and producers reduce the risk of deterioration, maintaining its nutritional value and weight. Cooling grain to below 15°C within two weeks of harvest reduces insect activity. This should then be reduced to below 12°C within 3–4 months of harvest to stop insect activity. Further cooling to below 5°C by the end of December helps prevent mite proliferation and preserves grain quality.

Polycool pedestals stand vertically within stored grain, using fans to draw heat out efficiently. Their twin-wall plastic construction and ribbed design prevent blockages, ensuring consistent airflow. Unlike traditional metal pedestals, which can be easily damaged and are costly to maintain, they are more durable and provide even cooling, reducing the risk of mould and insect infestations.

Unlike permanent underfloor systems, pedestal ventilation is cost-effective, easy to install and flexible. It allows targeted cooling, reducing energy costs while preserving grain quality. The slotted base design ensures air is drawn across a wider area, improving efficiency and preventing uneven temperature zones within the grain store.

Grain Fan Assist automates fan operation based on temperature differences, ensuring fans run only when needed. This reduces energy consumption by up to 40%, speeds up cooling times and prevents warm air from undoing previous cooling efforts. It’s a smart, wireless solution for optimising grain storage conditions.
Our pedestal ventilation and Grain Fan Assist systems can be integrated into existing grain stores without major infrastructure changes. This makes upgrading affordable and efficient, allowing farmers to improve cooling performance without costly renovations or downtime.
Evans and Pearce offer single-phase and three-phase fans, including Grain Fan Assist Wireless models that automate cooling. These fans vary in power and airflow capacity, ensuring farmers can select the right option based on store size, grain type and cooling requirements.
Differential temperature cooling ensures fans activate only when outside air is cooler than the grain, preventing unnecessary energy use. This method accelerates cooling, maintains grain quality, and avoids drawing warm air into the store, which could lead to spoilage.
Regular checks on fans, pedestals and temperature probes ensure optimal performance. Cleaning ventilation slots, inspecting electrical connections and monitoring grain temperature help maintain efficiency. Evans and Pearce’s durable designs minimise maintenance needs, making their systems reliable and long-lasting.
Factors like store size, grain type and climate influence the ideal setup. Evans and Pearce provide expert guidance to help farmers choose the best combination of pedestals, fans and automation for efficient cooling and long-term grain preservation.
