Description

Technical Field

[0002] With the deepening implementation of national and industry policies on energy conservation and emission reduction, energy-saving design of vacuum rehumidifiers for tobacco has become a development trend. Traditional steam jet vacuum devices with high energy consumption will gradually be replaced, and energy-saving vacuum devices will become the mainstream in the market.
