The invention discloses a constant-temperature and constant-humidity heat pump drying device for cured meat. An air uniform device is arranged in a chamber; the air uniform device can convey horizontal air into a drying chamber through an air outlet; a material loading device for hanging to-be-dried products is arranged in the drying chamber; an air inlet of the air uniform device is connected with an air circulating device which is arranged above the drying chamber; one end of the air circulating device and one end of the drying chamber away from the air uniform device are both communicated with an air return area; a heat pump medium adjusting device is arranged on the heat pump drying device and is used for adjusting the temperature and humidity of the air return area; a temperature and humidity sensor is arranged in the drying chamber and/or the air return area and is electrically connected with a master control circuit; and the master control circuit is respectively in electric connection with the air circulating device and the heat pump medium adjusting device. The invention also provides a drying technology for a cured sausage that uses the constant-temperature and constant-humidity heat pump drying device for cured meat. According to the invention, the drying process of the cured meat can be accurately and effectively controlled, the energy consumption and the production cost can be reduced, the effective control on the temperature and humidity in the drying process can be realized and the device can be applied to production control on various cured meat.
