Description

Agricultural and food dryer integrated platform system reflecting heat pump connection The present invention relates to an integrated platform system for an agricultural food dryer, and more specifically, to an integrated platform system for an agricultural food dryer that incorporates a heat pump connection. The biggest problem in the agri-food drying process is excessive energy consumption and the resulting cost burden. Conventional drying systems primarily operate by using electricity or gas as a heat source. This method is particularly inefficient in terms of energy costs and leads to low energy efficiency in large-scale drying processes. Furthermore, large-scale farms and food processing companies face a continuous economic burden due to the high costs required to operate drying processes. Furthermore, conventional agri-food dryers often operate under standard operating conditions set for specific types of food, making it difficult to provide optimal drying conditions for a wide variety of products. While appropriate temperature, humidity, and drying times vary depending on the type of food, existing systems struggle to analyze or control these individual conditions in real time. Consequently, problems such as excessive drying or insufficient drying of specific products may occur, posing a risk of quality degradation and loss of productivity. Conventional technology also has the problem of not being able to effectively utilize natural energy sources such as solar thermal and solar photovoltaic energy. With the recent advancement of renewable energy technology, energy-saving systems utilizing solar photovoltaic energy and Energy Storage Systems (ESS) are gaining attention, but they are rarely applied to agricultural food dryer systems. Existing dryer systems lack the equipment structure or operating system to organically integrate complex heat sources such as solar power generation or heat pumps. Consequently, the energy savings that can be obtained through such systems are not realized, and inefficient operation continues, particularly in large-scale drying processes where energy saving is critical. Furthermore, conventional technology lacks systems capable of monitoring and controlling the operational status of food dryers in real time. While food dryers generally operate automatically according to pre-set conditions, it is difficult to take immediate action even if unexpected problems arise or energy loss occurs in specific areas. Additionally, there is a absence of a big data system to integrate and manage system data for analysis, which can then be utilized to improve the drying process in the future. Due to these issues, long-term system operation optimization is difficult, and inefficient drying conditions may persist. Finally, existing agri-food drying systems have limited smart capabilities, making customized operation difficult. Since they do not provide an environment where managers can intuitively understand and control drying status, it is difficult to incorporate additional feedback beyond set operating conditions or to optimize operations tailored to the specific characteristics of agricultural products. For instance, functions to adjust temperature or humidity to match user-desired drying levels are limited, and it is difficult to respond immediately to unexpected environmental changes or system malfunctions. These issues ultimately have a negative impact on the quality and production efficiency of agricultural products. To solve such problems, the present invention provides an integrated platform system for agricultural food dryers that links solar power generation with a heat pump, digitizes optimal drying conditions for various agricultural foods, and incorporates smart control and integrated management functions to simultaneously improve energy efficiency and operational convenience.
