However, by directly adding low temperature materials into the distillation equipment and heating the low temperature materials, the temperature of the distillation equipment will change, causing the distillation equipment to no longer maintain a constant temperature, and more heat will be consumed for distillation.

[0011] Beneficial Effects

[0012] The utility model provides a constant temperature energy-saving distillation device. Compared with the existing technology, it has the following beneficial effects:

[0013] (1) The utility model heats the water in the constant temperature cylinder by the electric heating plate, so that the steam generated by the water heating in the constant temperature cylinder passes through the steam pipe to the air inlet pipe, and the air inlet pipe discharges the steam through the curved pipe and the air outlet pipe. The steam in the curved pipe will transfer heat to the material box, so that the material can be preheated well, and the temperature can be effectively prevented from being affected by directly passing cold materials into the distillation tower, which can well reduce the use of electric energy of the electric heating plate and achieve energy-saving effect.

[0014] (2) The utility model uses multiple buffer plates so that the falling materials will pass through multiple buffer plates, thereby slowing down the material feeding speed, increasing the material evaporation time, and improving the material distillation efficiency. The temperature in the distillation tower is monitored by a temperature sensor. If the temperature is too high and exceeds the constant temperature, the single chip will control the electric heating plate to turn off and stop heating, so that the temperature in the distillation tower reaches the constant temperature and then continues to heat and maintain it.
