The industry sector has a significant responsibility for the depletion of fossil fuels and emission of carbon dioxide. Thus, several initiatives have been implemented by the industry sector to mitigate those issues. One initiative corresponds to the implementation of energy efficiency strategies. In particular, the food industry is heavily dependent on fossil fuels, and the food demand is expected to grow significantly in the coming years. Therefore, developing energy efficiency strategies for this particular industrial sector is crucial. This paper investigates the different opportunities for energy efficiency in the food industry. It first provides a brief overview of the various food industries and related energy consumption. Then, the different options for energy efficiency in the thermal and electric sector are discussed. New trends and opportunities, arising from industry 4.0 and demand response, are also presented.INDEX TERMS Energy efficiency, food industry, industry 4.0, renewable energy, waste-to-energy.

“…The distribution of the fuel in the granules, as a raw material, is determined by the ore blending structure and the granulation process [32]. Segregation determines the fuel distribution in the sinter layer and the temperature profile of the sintering process, which in turn affects the sinter quality [33].…”

“…(3) Based on the optimization model for the fuel distribution, the fuel conditions, such as particle size composition and segregation characteristics, are found to match the theoretical coke content of each unit. The distribution of the fuel in the granules, as a raw material, is determined by the ore blending structure and the granulation process [32]. Segregation determines the fuel distribution in the sinter layer and the temperature profile of the sintering process, which in turn affects the sinter quality [33].…”

An optimization model for the fuel distribution of the material layer with mechanism models and algorithms is presented, which can reduce the fuel ratio of ore blending and enhance the fuel content in the upper layer to improve the homogeneity of the sinter quality. The actual fuel distribution of the material layer is analyzed through the granulation model and the theoretical fuel distribution for each unit is obtained using the numerical model. Then, the fuel particle size composition and segregation characteristics are optimized via the particle swarm optimization algorithm to bring fuel distribution close to the theoretical value, with a sum of their absolute values of 0.025. In comparison with the initial conditions, the fuel particle size composition conforms to a normal distribution with increased coarse particles, and the deviation of the granules from the vertical direction of the sinter layer decreases. Through this optimization method, the sinter bed with the ideal thermal profile can be achieved, namely uniform sintering along with a reduced coke ratio.

“…Currently, there has been much research [1][2][3][4] on using biomass from agricultural and industrial activities as a source for biofuels and bioenergy due to the reduction of conventional fossil fuel, as well as the negative impacts such as climate change, global warming, and emission from fossil fuels. Thus, utilization of renewable energy resources like solar, wind, hydro and biomass is the way to overcome these issues.…”

This study investigated the effect of air equivalent ratios (ERs) (0.1-5) on the temperature distribution in the fluidized bed reactor during gasification and combustion process. The cylindrical reactor with the diameter of 20 cm and height of 150 cm was used in this study. The conical shape connector was installed at the bottom of the reactor for different air supplying patterns, including tangential flow and up-flow. The mixed oil palm cake was used as a feedstock. The temperature distribution in the reactor during combustion and gasification process was observed by applying the numerical calculation using ANSYS software (Ver.19.0, Fluent) with 3D model. The effect of air supplying patterns and air equivalent ratios were then investigated. The results showed that the temperature distribution obtained from simulation was not consistent with the experiment results for an up-flow air supplying method. In the case of tangential air inlet, the results from simulation were similar to the experimental results. Consequently, these results will be the guideline for further studies of biomass gasification and combustion using fluidized bed gasifier with different inlet air patterns and ERs.
