Introduction

PHNIX's belt-type low-temperature drying technology employs the principle of low-temperature closed-loop dehumidification, using a heat pump as the heat source. It converts the moisture in sludge into humid air, which is then cooled and dehumidified by the heat pump system to achieve material drying.

This technology offers several advantages, including low exhaust temperature, strong drying capacity, high efficiency, and low operating costs. It can reduce the moisture content of sludge from 82% to 10%-60%, achieving over 50% energy savings and an 80% reduction in sludge volume.

As a low-energy, pollution-free drying and volume-reduction technology, it is widely used in the drying and volume-reduction projects of municipal and industrial sludge (such as from textile dyeing, papermaking, electroplating, chemical, leather, and pharmaceutical industries), livestock biogas residues, and animal feed.
