Heat Pump Tower Dryer

Significant environmental protection effect

The dehumidification heat pump drying principle is adopted to achieve high-quality drying of grain and economical and efficient heat energy utilization. Since the system does not have any oxidation combustion process, there is no emission of CO2, SO2, NO2, and slag, which saves energy and reduces consumption, and has obvious environmental protection effect

The closed hot air circulation recovery technology is adopted, and a reliable dust removal system is used to collect impurities, floating objects and dust generated during the drying process, effectively achieving near-zero pollution to the surrounding environment. The system has a recovery rate of more than 95% for bran dust

Long service life Strong working reliability

The service life of the heat pump continuous grain drying system is 8-12 years, which is about 100% longer than the 5-6 years of the traditional heat source drying tower

The process technology is mature, the performance is stable, safe and reliable, and the heat pump system of the heat pump continuous grain drying device is composed of a multi-stage heat pump unit. Each stage of the heat pump unit uses multiple steam compression heat pump systems to operate simultaneously, and the maintenance downtime failure is low

High material drying quality

Use medium and low temperature drying methods to calibrate, constant temperature, and hot air drying of grain and cash crops (the highest wind temperature is 80°C)

The dried grain has no cracked waist, no sticky grains, is clean and tidy, has constant physical and chemical indicators, and is of excellent quality. It meets the requirements of breeding, pharmaceuticals, food processing, high-quality commercial grains and national commercial storage. The bulk density of the grain after drying is 2%-3% higher than that of the traditional heat source drying tower

High degree of automation

Adopt plc integrated control

Adopting automatic constant temperature control, 24-hour continuous drying operation, high degree of automation and intelligence, simple operation, reduced labor costs, and reduced labor intensity of workers

High efficiency and energy saving

The heat pump heating COP can reach more than 4. Compared with the traditional heat source drying device, the heat pump drying device has high energy efficiency and the drying cost is reduced by more than 40%

Improve work safety

Since there is no combustion process in the whole work, for the working environment with higher fire protection level, the risk of fire caused by improper operation of open flame combustion is eliminated, and the probability of fire accidents is reduced
