“…On similar pasteurization with a different temperature, the protein content would also be lesser. These findings are in accordance with the statement of [29] that the protein content is influenced by temperature and duration of cooking, including pasteurization. [30] added that the pasteurization's duration and temperature influence the protein denaturation level.…”

Efforts must be conducted to utilize all resources due to the rising vegetarian population, decreasing food supply, high cost of animal-based food sources, increasing lactose intolerant population, and health reasons. Therefore, this research aims to utilize jackfruit seeds as the ingredient of plant-based milk that is nutritious and liked by the panelists from its color, flavor, aroma, and mouthfeel through determining the exact temperature and pasteurization period during its making. This research uses the experimental methods with a factorial Randomized Block Design, in which the first factor is the pasteurization temperature (T1: 60oC, T2: 70oC, and T3: 80oC), and the second factor is the pasteurization period (L1: 1 minute; L2: 2 minutes, and L3: 3 minutes). Each treatment combination is repeated three times. The research shows that jackfruit seed milk using different temperature and pasteurization periods contains 2.32-3.25% protein, 1.02-1.18% fat, and 10.50-12.00obrix of total soluble solids. The overall result of the sensory test (color, flavor, aroma, mouthfeel) shows that the panelists like jackfruit seed milk. The utilization of jackfruit seeds in plant-based milk is one of the solutions to provide alternative beverages with nutrition contents similar to cow milk and reduce the dependency on soybean, whose price continues to rise.

“…There is a wealth of literature on the modeling of heat exchangers in hydraulic applications, e.g., [33][34][35][36][37]. In line with our application in an optimization context as well as our modeling principles (see Section 3.2) that require the model to be highly flexible, expandable with low complexity, and thus with little effort for parameter identification, we model the plate heat exchanger as a series of cells in each fluid path.…”

The Faster the Better? Optimal Warm-Up Strategies for a Micro Combined Heat and Power Plant

The warm-up process is a critical operation phase for mCHP plants, directly impacting their efficiency, reliability, and lifetime. As small decentralized power generation units are increasingly expected to be operated on demand, start-ups will occur more frequently and thus the importance of the warm-up process will further increase. In this study, we address this problem by presenting a mathematical optimization framework that finds optimal actuator trajectories that significantly reduce the warm-up time and improve the thermal efficiency of an mCHP plant. The proposed optimization framework is highly flexible and adaptable to various objective functions, such as maximizing efficiency or minimizing the deviation from desired temperature references. The underlying mathematical model has been experimentally validated on a physical mCHP test rig. Selected case studies further demonstrate the effectiveness and flexibility of the framework and show that with the optimized actuator trajectories, the mCHP plant can reach its steady-state operating temperature in 40% less time. The results also indicate that the shortest warm-up time does not necessarily lead to the highest thermal efficiency. Accordingly, the methodology proposed in this paper provides a powerful tool to study higher-level operational strategies of mCHP plants and thus to maximize their overall performance, which directly translates into an improved operational cost-effectiveness, particularly in demand-driven energy landscapes.

“…The designs of HEs were reviewed in numerous studies [28][29][30][31][32] such as double tube HX [33][34][35][36][37], plate HXs [38][39][40][41][42][43][44][45], finned HXs [46][47][48][49][50][51], and shell and tube HXs [2,[52][53][54][55]. The authors aim to conduct an extensive examination of HTE methods in HTHX.…”

In contemporary times, Helical tube heat exchangers (HTHXs) have gained significant prominence in energy-related sectors, frequently finding application in industrial and technical settings. Their impact on overall system efficiency and size is substantial. A comprehensive review addressing passive methods of heat transfer enhancement in HTHXs is notably absent. This paper justifies its significance by providing a recent and systematic review of available passive methods. The passive approach offers advantages such as the absence of external power requirements and lower operational costs compared to active methods. Studies collectively indicate a noteworthy progression in heat transfer enhancement in HTHXs. The paper meticulously evaluates passive methods like fins, inserts, geometry modifications, and baffles, which collectively represent 18.7%, 22.3%, 42.2%, and 16.8% of research efforts, respectively. Both experimental and numerical studies focus on improving heat transfer in HTHXs. However, further exploration is necessary to understand the negative effects of pressure drop in tube-side flow. Future research should also prioritize the development of geometric designs for HTHX surfaces, potentially incorporating materials coatings to further enhance heat transfer. The authors present insightful issues and ideas that they estimate deserving of additional investigation in subsequent research endeavors.
