Increasing energy efficiency is one method of lowering primary energy consumption, reducing greenhouse gases emissions and decelerating climate changes. It can be achieved, among the other, by reusing the waste energy generated in each production process. In the industrial cultivation of vegetable sprouts for food production purposes, significant amounts of heat are released by the metabolic processes inside the seeds. In traditional installations, this energy is released to the environment and irreversibly lost, while it could be reused i.e. for heating water used for watering plants. This paper presents the results of experimental and modelling research to determine the feasibility of implementing internal low-temperature waste heat recovery in Mung bean sprout production using a plate heat exchanger. Based on experimental results on an industrial vegetable sprout cultivation plant, the total amount of heat generated during a complete sprout growth cycle was estimate to be 5,15 GJ. To identify the potential energy that could be recover for the internal needs of this plant, the numerical modelling was applied using FlownexSE simulation software. The full simulation model of installation for sprouts cultivation was elaborated, and nonstationary numerical calculations of a whole sprouts growth cycle were performed. The calculations showed that the recoverable thermal power could reach a maximum value of approximately 800 kW, and almost all waste heat may be recovered.
