Abstract
The invention provides a dryer with a Stirling heat pump. A Stirling reversible heat engine is used as a heat pump, and the design concept of direct drainage of the dryer is embodied. The Stirling heat pump and a drying container are connected into a sealed circulating heating and cooling system through an air duct from a heat outflow end to the drying container, an air duct from a heat inflow end to the heat outflow end and an air duct from the drying container to the heat inflow end. A condensed water outflow pipe is arranged at the bottom of the heat inflow end, so that water formed by the condensation of high-humidity air at the heat inflow end is drained. Dehumidified and cooled air is heated at the heat outflow end, and immediately enters the drying container to heat a material, moisture is converted into steam, and the steam is brought to the heat inflow end. Such a process is circulated to dry the material. Such a drying mode is energy-saving and environment-friendly. Air exchange between the heating and cooling system and the outside is avoided, so that quality of fine chemical products, agricultural products and medicinal materials, which are easy to pollute, can be ensured, and environmental pollution caused by pollutional materials can also be avoided.
