Perry of Oakley Ltd

Perry of Oakley Ltd was founded in 1947 by Tom Perry, a farmer’s son, who offered a manufacturing service to local farmers and businesses in Oakley, Basingstoke.

We built our first continuous grain drier in 1954 and our first chain and flight conveyors and bucket elevators in 1949 and the early 1950’s.

In 1952 our first factory was built in Oakley, and was just 2000 sq. ft. By 1974 we had our first purpose built factory. Over the next 16 years the business continued to grow and expand under the direction of Tom’s son, Nigel Perry. In 1990 we relocated to Honiton in Devon to larger premises. In 1991 Nigel’s son, David Perry, joined the company after achieving a First Class Honours degree in engineering. 

In 2007 David Perry took over as Managing Director. The factory now occupies 52000 sq. ft., on a 2.5 acre site. We use the latest CAD CAM technology, automated punching and forming machinery and our designers and technicians have years of experience in the bulk materials handling trade.

All of our products are designed and manufactured in our purpose built factory using a depth of knowledge acquired during more than 60 years of business, and using our in house staff we provide expert technical support for our machinery worldwide. 

Examples of products handled include grain, minerals, animal feed, wood waste, pellets, dusts, woodshavings, wood chip, sawdust, pet food, and compost to name a few.

Our experience and in depth engineering knowledge is our strength. You know that when you purchase a Perry product you are buying a quality made British built product that is backed up by a third generation, 60 plus strong family owned highly experienced company.

We have a strong UK customer base and export to many countries around the world.

We back up our equipment with a large stores facility in Devon and we have a network of engineering staff who are available for site visits if required.

Products & Services

Chain & Flight conveyors

  • Capacities up to 60 tph (wheat @ 750kg/m3)
  • Heavy duty specification. 3mm thick base and 2mm thick sides (thicker options available).
  • Perry heavy duty precision roller chain with deep faced flights as standard - ideal for handling cereals, pulses & granular products.

  • 3 piece trough construction allows base to be thicker than the sides providing a longer life.
  • Deep flights mean most conveyors are suitable for inclined applications.
  • These conveyors are supplied as standard in modular lengths with loose inlets and outlets to allow faster delivery.
  • Inclined conveyors can be used at angles of up to 30 degrees. Also with the use of a cable span brace any conveyor can span 12m unsupported.

Curved Combinations

  • Curved machines used to feed elevator boots remove the need for elevator pits
  • Replace a belt and bucket elevator and horizontal conveyor with one curved 90° from horizontal to vertical (Capacity up t 50tph)
  • Benefit of reduced number of machines and hence easier and quicker installation and less wiring work
  • Horizontal / curved machines can be used to enter buildings and follow the roof line for maximum height

Levelling conveyors

  • These conveyors are suspended on tracks at the side of a building and have an open bottom to allow grain to fill the building starting at one end and building up to the base of the conveyor.
  • It will fill a grain store with a completely level un-compacted layer of grain ideal for under floor ventilation and drying.
  • They remove the need for a loader & grain pusher to fill the store to its optimum

Travelling conveyors

  • These conveyors are still suspended from beam trollies but they do not have a fully open bottom. They have individual outlets instead to fill bins or bunkers in a particular building when there is little headroom
  • They can also be used to fill floor stores with peaked fill when surcharging storage.

Belt Conveyors

A belt conveyor can be positioned in the apex of the building and a winched tripper can discharge grain all the way along the building avoiding the peaks and troughs formed by using a chain and flight conveyor with separate outlets.
  • There are also many inclined applications up to 30 degrees depending on the product being handled.
  • 3 piece steel trough construction or with a 3 roller trough belt assembly.
  • These designs give an exceptionally rigid construction, easily capable of spanning 6m building bays.

Grain Driers

Continuous Mix Flow Drier

A tried and tested way of moisture removal - High output with efficient fuel and electrical usage.

  • All Perry driers are designed and manufactured in house, to conform to British and international standards.
  • Full technical support and servicing direct from the manufacturer.
  • Very latest PLC program and control panel designed and programmed in house.
  • Capacities from 8 to 100 tph.
  • Widths from 2M to 8M
  • Designed to BS6399 and BS5950 for structural strength and wind loads calculated on a 50 year event.
  • Fully galvanised
  • Highly efficient pneumatic shutter discharge.
  • 2mm thick grain column.
  • The Perry drier has a completely ledge free grain column to help prevent the hang up of straw or dust
  • Tapered duct design aids an even air speed across the entire drier width
  • The top row of ducts in the drier are manufactured from 3mm galvanised steel to prolong life.
  • The column also has unique design features to promote even grain flow.

Dual Column Driers

  • These driers combine the high capacity of a large drier combined with the flexibility of being able to use either half for drying small batches.
  • If there is only a small amount of crop to be dried then only one column needs to be used.
  • One column can be left filled with one crop whilst the other column is used to dry another. This significantly reduces lost time spent filling and emptying the drier between batches

Fuel & Burner Options

  • Diesel
  • Kerosene
  • Natural gas
  • LPG
  • Dual fuel (gas and oil in the one burner)
  • Biomass

Drying Light Seeds

  • The Perry drier has a fan bypass plenum to allow air to be bled directly into the fans from ground level. This ensures that airspeeds are not increased in front of the full ducts.
  • The PLC panel also gives the option to turn a fan off if a drier has multiple fans. (Fan shutters must be fitted to use this)
  • To help achieve the low temperatures required when there is also low air flow due to the lightness of the crop the PLC panel has the ability to turn burners on and off to maintain the low temperature if fitting smaller jets is not enough.
  • Optional inverter control for the drier fans to reduce energy consumption and crop lift off when drying light crops. 

Servicing & Commisioning

All Perry driers are commissioned by our own experienced engineers who will also provide expert technical advice for complete satisfaction. Our engineers are available to carry out:-

  • Commissioning
  • Drier servicing

We also have a dedicated technical support line to provide a first point of call for all technical enquiries for all products including driers and their control panels.

Access & Cleaning

  • There are large access doors into the exhaust plenum. These also allow cleaning out of any blockages that may occur in the baffles above the discharge shutters.
  • The internal of the drier has a lot of cross bracing which is dimpled to provide a non slip surface. These can be used as a ladder to access the drier for cleaning and inspection. Harness attachment points are at every level.
  • Sight glasses in exhaust plenum allow monitoring of dust and chaff build up.

Drier Discharge

  • All Perry driers are equipped with a pneumatically operated fully galvanised shutter discharge system.
  • The length of the opening time and the frequency is fully adjustable from the drier PLC panel.
  • Twin rams fitted on 2, 3 and 4M drier discharges.
  • 4 rams fitted on 5 and 6M drier discharges.
  •  Pneumatic control panel mounted on the side of the discharge.
