The invention relates to a laboratory vacuum electric heating oven. The laboratory vacuum electric heating oven comprises an oven cabinet and a cabinet door. An oven chamber and a control plate are arranged in the oven cabinet. The oven chamber comprises a bearing mesh plate, an electric heater and mechanical stirring systems. Each mechanical stirring system comprises a stirring motor, a stirring shaft clamping claw and a stirring paddle. A vacuum pump and an air filtering column are further arranged in the oven cabinet. One end of the vacuum pump communicates with the air filtering column, and the other end of the vacuum pump communicates with the atmosphere. An air outlet of the oven chamber communicates with the air inlet end of the air filtering column, and an air outlet of the oven chamber communicates with the atmosphere. When the laboratory vacuum electric heating oven dries laboratory medicines, stirring can be provided while drying is conducted, the medicines are volatilized evenly in the drying process, and caking is avoided after drying; and medicine solutions with large viscosity are dried and stirred at the same time, the drying speed is increased, and the drying effect is improved.
