How do you know which type of grain drier is best for your needs?
Continuous Flow Grain Driers
Ideally suited to granular and free-flowing products such as grain, maize, rape, pulses, and cereals, we now offer two ranges of continuous-flow grain driers; the Mistral and the Savannah.
The Mistral
This entry-level economy grain drier is designed to handle up to 30tph of combinable cereals, making it an ideal choice for small to medium-sized farms. Despite its more affordable price, the Mistral is still capable of delivering excellent drying performance. It uses a combination of high-temperature and low-temperature drying to remove excess moisture from the grain. This approach ensures that the grain is dried quickly and efficiently, without compromising its quality.
It’s designed to be user-friendly and intuitive, so you don’t need to be a grain-drying expert to operate it. This can be a huge benefit for farmers who are looking to streamline their operations and save time. In addition to its ease of use, the Mistral is also designed to be low maintenance. It has a simple and robust design that requires minimal upkeep, reducing the likelihood of breakdowns and downtime.
Key points
- Designed with the same efficiencies and expertise as the Savannah Series Driers. 1.6mm thick grain column and air ducts, which has a completely ledge-free design to reduce dust and chaff residue.
- 25% to 30% of the drier is used for cooling the crop before it goes to storage. This prevents deterioration of the grain when in store. Additional ventilation will still be required.
- Fully galvanised construction for outdoor use.
- Burner and fuel options – diesel, kerosene, gas steam, coal using heat exchangers or biomass heat sources as options (direct or indirect fired).
- Highly efficient axial flow fans – Optional inverter-controlled fans for ease of control when drying light crops and for energy saving.
- Discharge – the Mistral range of grain driers are fitted with the Perry’s proven, simple to operate, roller discharge (shutter discharge is optional).
- CentriKleen – the cost– effective, simple solution to dust and chaff problems, which can be fitted to existing axial fans on all makes of drier.
- Fire detection – can help provide early warning of a fire, helping to reduce potential damage to the drier. Detects fire within a grain drier drying column.
- Commissioning and support – there’s a dedicated technical support line to provide a first point of call for all technical enquiries on any Perry machine.
- Control Panel – as standard, the Mistral drier is controlled via a hard-wired control panel, though this is easily upgradable to the Perry PLC Touch Screen Control Panel, using inhouse written software. Connect the drier to the internet to allow UK engineers access to the panel for diagnostics and adjustments.
- Automatic crop set up page – select the crop and moisture content, and the control panel will set all temperatures, fan speeds and discharge speed to suit.
The Savannah
The Savannah capacity range is ideally suited for both larger farms and commercial grain stores. This makes it a versatile choice for anyone who needs to dry large quantities of grain, regardless of whether they’re a farmer or a commercial operator.
Its industrial design and versatility make it an excellent choice for anyone who needs to dry large quantities of grain.
Key points
- Heavy duty commercial specification grain drier built to BS6399 and BS5950.
- Widths from 2m to 8m single and 12m dual column with capacities from 5 to 150tph.
- To promote consistent movement of the grain, Savannah Series Driers are available with our highly efficient, fully galvanised, pneumatically controlled shutter discharge (with phosphor bronze bushes on all wearing parts). Pneumatic shutter discharge ensures even movement of crop across the whole bed.
- The grain column has a completely ledge free design to reduce dust and chaff residue. The tapered air ducts promote even air flow and uniform drying across the whole grain column.
- Variable cooling section so you can change from minimum to maximum cooling by using control levers from ground level.
- 25% to 30% of the drier is used for cooling the crop before it goes to store. This prevents deterioration of the grain when in store; additional ventilation will still be required.
- Touch screen PLC control interface with mobile phone app for monitoring and controlling your drier remotely. Receive status updates, warnings for alarms and change settings wherever you are over the internet.
- Automatic grain moisture control system as standard. This uses temperatures at the top and bottom of the drier to monitor incoming and outgoing grain moisture changes and control the drier discharge speed accordingly.
- Optional automatic grain sampling system which takes a sample of grain, and is analysed using the latest Near Infrared technology. The results are used by our own software to determine the correct drier speed to maintain the optimum moisture content.
- Optional inverter controlled fans for ease of control when drying light crops and for energy saving.
- Automatic crop set up page. Select the crop and moisture content, and the control panel will set all temperatures, fan speeds and discharge speed to suit.
- You can connect the drier to the internet allowing UK engineers to access the panel for diagnostics or adjustments while you watch the screen.
- Burner choices are diesel, kerosene, gas, steam, coal using heat exchangers or biomass heat sources as options. Direct or indirect fired.
- CentriKleen – the cost effective, simple solution to dust and chaff problems, which can be fitted to existing axial fans on all makes of drier.
- Fire detection – can help provide early warning of a fire, helping to reduce potential damage to the drier. Detects fire within a grain drier drying column.
- Commissioning and support – there’s a dedicated technical support line to provide a first point of call for all technical enquiries on any Perry machine.
- Combined with the use of curved conveyors the drier and handling needs only a flat concrete pad. This means much more cost-effective concrete work and straightforward calculations.
- Tried and tested design with years of proven track record.
- We have our own dedicated research and development drier at a grain cooperative. This gives us access to a drier operating under real life conditions and the capability for extended test runs for all new product developments and to enhance our R&D capabilities.
AGREX Mobile drier
The AGREX Mobile Drier range spans 5 to 55 cubic M and are high-specification driers supplied in a durable painted finish for use inside or out. The AGREX mobile drier range can fully integrate with the Perry range of bulk materials handling and storage so all your drying, handling and storage requirements can be managed by one supplier making your life easier.
Key points
- Capacities from 7 to 42T.
- Basic operation, hard wired semi-automatic panel or fully automatic PLC panel to allow unattended operation and remote connectivity via a mobile data network. Receive status updates as they happen using the PLC option.
- Models from 7.5 to 25T have the unique feature of an external auger, meaning access for servicing is easier and quicker to collapse for transit. With no centre auger the heated airflow is more uniform in the cone plenum; this increases performance. Less fuel usage as no heat is transferred to the centre auger.
- The external auger also allows the drier to have an independent mixer in the bottom and a control slide to control the rate of grain mixing during the drying process.
- Reliable Ecoflam two stage burners.
- Full stock of spares, and support, in the UK.
- Tried and tested in the UK for over 5 years.
- The 1.5mm stainless steel screen material means the drier is suitable for oil seed rape and most UK combinable crops.
- Two-year warranty period.
- The patented, stainless steel heat exchanger option can change from indirect to direct fired and as such still provide the full range of drying temperatures and efficiencies.
- There are fewer motors, meaning more reliability and a smaller electrical requirement, which can be a very important consideration for some farms.
- Large inlet tipping hopper, or an option available suitable simply for filling by an intake and elevator combination.
- For added safety and control of the process there are three temperature sensors, one for hot air temperature, one for hot grain temperature and an additional fail-safe alarm temperature sensor.
- Very high quality paint finish to ensure a long outdoor life.
- Dual point aspiration as an option.
- Heavy duty specification.
- Quality drier made in Europe.
- Can run multiple batches unattended.
- Diesel, kerosene or gas fired.
