“…e daily pasteurized milk in September is 69.19 l/day and 58.59 l/day, and in November, it is 70.2 l/day and 60.24 l/day for FPSC integrated with and without the reflectors, respectively. As shown in Table 4, due to the addition of reflectors on both sides of the collectors, the thermal efficiency and the quantity of pasteurized milk is higher by 6.9% and 9%, respectively, compared to the results of Atia et al [17].…”

A large share of Ethiopia’s milk production comes from its rural areas. However, this milk does not undergo further processing into dairy products on a large scale due to lack of conventional energy sources such as electricity and gas. Hence, the country is not utilizing its milk resources to the maximum possible. In this study, the possible use of solar energy for the milk pasteurization process is investigated by using a flat plate solar collector (FPSC) with and without reflectors integrated. Reflectors added to the FPSC have augmented the incident solar radiation on the collector from 0.27–0.91 kW/m2 to 0.36–1.18 kW/m2. The thermal efficiency obtained for the FPSC with reflectors integrated is 51.8% whereas that of the collector without reflectors integrated is 46.2%. Likewise, the exergy efficiency is found to be 5.43% for the collector integrated with reflectors and 2.53% for the collector without reflectors. Also, an increase in the daily processed milk production of 18% is observed in September and 16% in November by using the solar collector with reflectors integrated. The quality of pasteurized milk is checked by using the methylene blue reduction test (MBRT) method, and it indicates a better quality of pasteurized milk when compared with raw milk. Therefore, this study shows that the use of solar energy for milk pasteurization has great potential to increase the shelf life of milk, and it can be used as an instrument to improve the quality of life of people living in rural areas.

Thermal processing is a technique for sterilizing foods through heating at high temperatures. Thermal processing plays a significant role in preserving foods economically, efficiently, reliably, and safely. Control in thermal processing of foods is necessary to avoid any decrease in food quality, i.e., color change, reduced content, sensory quality, and nutrition. Artificial Neural Network (ANN) has been developed as a computing method in research and developments on thermal processing methods to discover one suitable for food processing without damaging food quality. To this date, ANN has been used in food industries for modeling many processes. The paper aims to identify the latest trend in intelligent neural network control for the thermal processing of foods. The paper conducted a systematic literature review with five research questions using Preferred Reporting Items for Systematic Review (PRISMA). According to screening results and article selection, 240 potential articles have fulfilled the inclusion criteria. Then, each article was explored to identify the advantage and the advance of intelligent network control in thermal food processing. It can be concluded that the technology in information and computations of food processing has rapidly developed and advanced through the utilization of a combination of ANN with fuzzy logic and/or genetic algorithms.

“…Use of flat plate collector for pasteurization (Zahira et al, 2009;Atia, 2011;Wayua et al, 2012) discussed remarkable results dealing with small quantity of raw product (milk). In order to get rather a higher temperature, some of them designed a system employing a tank and evacuated tubes for low cost solar operated milk pasteurizer (Doborowsky et al, 2015).…”

“…Franco et al (2008) designed a Fresnel type concentrator based pasteurizing system. The goat milk (10 L) was cooked using steam in an isolated container in about 1 h. Atia (2016) conducted an experimental study to equip a solar concentrator with dual axis sun tracking device for milk pasteurization. The thermal system was comprised a solar parabolic dish, energy conversion sub-system, and heat exchanger.…”
