Advanced controls on grain dryers

Advanced controls on grain dryers

Manual control in grain drying operations with large variations in moisture often leads to significant overdrying or underdrying, and is highly inefficient from an energy point of view. Feedback-based automatic controllers can help to minimise energy consumption by controlling energy inputs more precisely to meet the needs of the product being processed. While preservation of grain quality is the primary benefit, energy savings of up to 20 percent can be achieved.

Power factor correction

Power factor correction

Some farmers are unaware that their electricity bills can be reduced by improving the ‘power factor’ (PF) of their facilities. A poor power factor is analogous to a beer with too much head, when the head represents wasted energy. Networks penalise facilities with poor PFs by increasing ‘demand’ (or ‘capacity’) charges. Installing power factor correction devices can help ensure that on-farm electrical equipment uses the voltage provided by the network efficiently and that penalties are not applied as a result of the facility making unpredictable demands on the system.

Solar hot water

Solar hot water

Solar hot water works well in buildings that have significant roof area on which to locate solar collectors. A solar hot water system should provide between 40 and 60 percent of your hot water needs. Solar hot water systems come with electric or gas boosters to provide the remainder of your hot water needs. Solar hot water systems use solar collectors – either solar panels or evacuated tubes – which absorb energy from the sun to heat water. The heated water is then stored in an insulated tank until you need it. Typical applications are in dairies, piggeries and worker accommodation.

Voltage optimisation units

Voltage optimisation units

Voltage optimisation can achieve energy savings of between five and 20 percent in situations where mains voltage is higher than is needed by farm equipment. In addition to enabling energy savings, voltage optimisation units protect electrical devices from variation – surges or drops – in mains voltage. Purchasing considerations include the type of unit and the presence of electronic devices in the circuit. The installed cost of a VO unit typically ranges between $150/kVA and $300/kVA.

Adaptive driving- the skill factor in fuel efficiency

Adaptive driving- the skill factor in fuel efficiency

Driver skill is a central element in achieving farm fuel efficiency. Modern diesel-engine tractors typically maximise their efficiency when operated within 60 to 80 percent of their rated power output. Maintaining this range requires skill and attention from the operator. Key factors in achieving efficient driving practices on farm are: driver skill, awareness and motivation; feedback systems provided by the machinery; and logging and analysing fuel consumption regularly. Fuel savings greater than 20 percent can be achieved in some situations.

Estimating tractor power needs

Estimating tractor power needs

This information paper provides guidance and calculation tools to enable you to determine the appropriate power (in kW or horsepower) that your field operations will require. It will allow you to determine the size of the tractor that best suits your needs without being under- or over-powered. This is of critical importance, as a machine that’s not well matched for the tasks it will perform is likely to operate inefficiently. This can lead to fuel waste or early breakdown.

Monitoring wheel slip to achieve fuel efficiency

Monitoring wheel slip to achieve fuel efficiency

Wheel slip is a key indicator of efficient tractor set-up and operation. The level of wheel slip serves as a proxy to indicate whether the right combination of tyre pressures, tractor weight (ballast) and tractor operating speed are resulting in the correct traction required to perform efficiently and save fuel. Many operators are misinformed as to the appropriate levels of slip.

Purchasing a fuel-efficient tractor

Purchasing a fuel-efficient tractor

If chosen correctly, modern tractors can deliver significant energy savings and operational efficiencies over earlier machinery. Tractors are increasingly specialised and complex, making it essential to match their features to specific farming tasks and environments. Below, fuel-efficiency factors are discussed in relation to usage requirements, dealer support, engine performance, chassis configuration, linkages and power take-offs, and wheel, tyre and ballasting features.

Tractor ballasting

Tractor ballasting

Often, Australian tractors are overballasted. Correctly setting ballast to match a tractor’s main duties can result in fuel savings of five to eight percent. Establishing correct ballast involves identifying goal weights for your main operations and measuring the actual weights at each axle, ideally while the equipment is mounted. Once ballast has been set in the right ball park, further adjustment may be unnecessary, since efficient traction can be achieved simply by adjusting tyre pressure. Taking a common-sense approach minimises the need for ballast changes but ensures that gross ballasting errors are avoided.

Tractor tyre selection

Tractor tyre selection

Tractor tyre specification is a key element in achieving fuel efficiency. Factors that need to be considered include tread, diameter, width, rim size, load indexes, single/double/triple arrangements and typical operating speeds. Unsuitable tyres may make it difficult or impossible to implement other fuel-efficiency measures. Larger tyres spread the weight and enable operation at lower and at a wider range of pressures.
