“…They could produce different outlet temperatures that varies from 30 to 1500 • C. The flat plate collectors have the outlet temperature of 80 • C with the possibility to increase to 100 • C with modification of the solar collector [42,55]. Those types of collectors had been used in the dairy industry before 2010 due to their simple design and operation compared to concentrating panels [60,63]. However, their temperature was not sufficient for the processes like evaporation and spray drying that require 200 • C [11].…”

“…Two collectors were designed: a parabolic used for milk pasteurisation at 75 • C and a flat plate collector connected to the absorption chiller that was used for cooling at 15-20 • C. It was found that the system was able to supply 150 litres of hot water per hour at 90 • C while the cooling power varied between 5.7 kW/kg and 5.4 kW/kg. The use of solar energy with flat plate collectors and solar water heaters could operate at the temperature of 63-72 • C for milk pasteurisation processes [47]; however, some concerns were articulated regarding the milk quality and further investigations recommended. Masera et al [48] reviewed the thermal demands in the dairy industry and recommended a concept design that uses solar collectors and thermal energy storage for solar thermal energy integration.…”

The Use of Solar Thermal Heating in SPIRE and Non-SPIRE Industrial Processes

This paper investigates the use of solar thermal energy systems in SPIRE (sustainable process industry through resource and energy efficiency) and non-SPIRE industries and evaluates the use a novel solar Fresnel collector for generating temperatures of up to 400 °C. The investigation showed that solar thermal energy systems were mostly integrated into the non-SPIRE industries like food and beverages, paper and pulp and the textile industries with temperature requirements of up to 150 °C while few of them were used in the SPIRE industries like the non-metallic minerals, chemicals, basic metals and water industries with temperature requirements of up to 1500 °C. The limitation of those solar energy systems was seen in their application in higher irradiance regions due to the limited operation temperature of certain types of solar collectors, which particularly affected the SPIRE industry sector. To increase their use in high and low irradiance regions, a novel solar thermal system developed by the EU-ASTEP project that could achieve a temperature of up to 400 °C was introduced. The calculations of the theoretical and technical potential application of the ASTEP system in EU industrial processes showed an increase of 43%, of which 802.6 TWh totalled the theoretical potential and 96.3 TWh the technical potential. This resulted in a reduction of greenhouse gas (GHG) emissions by 24 thousand kt CO2 equivalent, which could help industries to achieve their 2050 targets for net-zero GHG emissions.

“…Many research studies have been conducted in the field of milk pasteurization through solar heat. In this context, Panchal et al (2020) reviewed the various research works done by other research scholars all across the globe for milk pasteurization using solar panels for rural areas and its feasibility. After analysis, they concluded that solar heat had a significant impact on the milk pasteurization technique.…”

India is one of the largest countries in the world, with a population mainly living in villages and primarily engaged in dairy activities along with agriculture. Despite being the largest milk-producing nation, lives of local farmers are challenging due to the lack of access to technology in rural areas. This study aims to develop an integrated system that can solve the problems faced by farmers by utilizing locally available resources. Due to the time lag between milking and storage, milk spoilage is more likely to occur in remote areas. Immediate pasteurization and storage facilities are required. Heating and refrigeration are essential for pasteurization. In India, most villages face power shortages, so biomass heat is suitable for pasteurizing milk. A steam jet refrigeration system is also proposed as it runs with waste biomass for chilling milk. Steam required for both heating and chilling milk is generated in the same biomass-fired boiler. Also, make-up water requirements in the boiler are fulfilled using a rainwater harvesting system. In a conventional dairy plant, a cooling tower is used to supply condensate water required in the condenser. Here this water requirement is fulfilled using a bore well. Subsequently, this water is stored in the irrigation pond to cool it by natural cooling through surface evaporation, making the water suitable for irrigation purposes. Also, the payback period of this system is estimated to be less than six months. Looking at the multiple benefits, this integrated system will further facilitate in achieving sustainable development goals through rural development by 2030.
