Scanair Solar Assisted Heat pump Dryers have been known to be energy efficient when used in conjunction with drying operation. It represents a schematic layout of the various refrigeration components and solar system integration with the drying chamber. The inlet drying air passes through the drying chamber and picks up moisture from the product. The moisture-laden air is then directed to the evaporator coil. During the dehumidification process, the air is first cooled sensible heat to its dew point. Further cooling results in water being condensed from the air. Both sensible and latent heats are then absorbed by the evaporator for boiling of the refrigerant. The recovered heat is pumped to the condenser heat dissipated by the solar collector the solar radiation from the sun is converted to sensible heat. Air passing through the number of pipes in the panel is then heated up. This heated air entering the condenser. The pre-heated and dehumidified air absorbs more heat from the condenser and then once that is higher temperature and properly dehumidified which readily flows through the drying chamber for drying application.
1. Higher energy efficiency with controlled temperature profile to meet product requirements.
2. Better product quality with well-controlled drying condition schedules to meet specific
production requirements.
3. A wide range of drying conditions typically from 20˚C to 100˚C (with auxiliary heating) is
4. Excellent control of the environment for high value products and reduced electrical
consumption for low – valued products
5. Suitable for both high-value and low-value products
6. Easy conversion of natural energy for direct heating and storage resulting in significant saving
of energy and better system efficiencies
7. Easy to implement controls strategy
8. Higher operating drying temperature compared to a standalone heat pump drying system
Open air sun drying has been used since long back in our country. However for large scale production the limitations of drying using the sun under the open sky are well known. Among these are high labour costs, large area requirement, lack of ability to control the drying process, spoil the products due to rain fall and wind, moisture and dust, loss of produce due to birds and animals, possible degradation due to biochemical or microbiological reactions. In order to benefit from the free and renewable energy source provided by the sun numerous attempts have been made in recent years to develop solar assisted heat pump drying systems. Solar heat pump drying technology offers an alternative which can process the products in clean, hygienic and sanitary conditions with minimum costs, important demands in industrial drying with respect to product quality control, reduced energy consumption and reduced environmental impact. For heat sensitive materials improved quality control can be achieved due to low drying temperatures and independency of outdoor dehumidified air reduced energy consumption is achieved due to the high coefficient of performance of the heat pump and the high thermal efficiency of the dryer when properly designed.
