1. Safety: The existing coal fired barn uses coal as a fuel to generate open flames. It is possible that flames may cause leakage of flames and cause huge losses to farmers. However, the PAKA heat pump barn's main unit (including power supply) is installed outside the barn, Heat transfer from the heat pipe to the baking room heating device to heat, so there is no open fire within the bar to achieve absolute safety. 2, Environmental Protection: The original coal burning barn uses coal as a fuel to roast and emit toxic gases such as carbon dioxide and sulfur dioxide to endanger the health of human beings. Other dust and fumes emitted by the coal-burning barn greatly reduce the air purity, and the storage site seriously affects the surrounding sanitation. PAKA heat pump room absolutely no discharge, the human body and the environment impact and harm to zero, so that tobacco farmers and residents in the tobacco area to bid farewell to the smoldering labor and living environment. 3, Energy-saving: The average cost of baking a room in the original coal burning barn is about 600 yuan, the same area of ​​PAKA heat pump barn is only about 420 yuan, reducing the cost of PAKA heat pump barn by 30% Intelligent automatic control, without special care, labor costs reduced by about 60%. 4, high-quality: the original coal-fired briquette use of artificial combustion of flammable materials to control the temperature, due to the tobacco farmers fire technology, physiological characteristics (rest), the quality of combustion materials and processing quality and other factors affect the temperature control and reach Baking technology requirements, resulting in unstable leaf quality, PAKA heat pump barn from the heat source automation, accuracy control has been completely resolved, accurate temperature reached ± 1 ℃, thereby enhancing the quality of the tobacco baking. 5, Provincial workers: The original coal briquette are heated with artificial combustion materials, requiring a lot of labor to purchase or process fuel, baking, but also keep feeding or cutting temperature to control the temperature, the tobacco farmer labor intensity is very Big. The PAKA heat pump barn can automatically control the temperature and humidity, without any fuel, thus greatly reducing the labor intensity of farmers, you can easily burn more than one barn at the same time. 6, Save time: Burning coal barn due to heating due to misuse and burning time and other factors lead to slow heating, resulting in a waste of baking time.PAKA heat pump barn from the fast temperature control, accurate, programmed to achieve Baking time standardized, the average per room baking time can save more than 24 hours.
