The invention discloses an electric heat generating device of a rotary evaporator. The electric heat generating device comprises a body, wherein the bottom of the body is provided with a first electric heating block and a second electric heating block; the first electric heating block and the second electric heating block are fixedly connected with an affiliated body through a pair of heat insulation clamp plates; the first electric heating block and the second electric heating block are not in direct contact with the body; a plurality of binding posts are also arranged on the body; the first electric heating block and the second electric heating block are of hollow structures; and the heat insulation clamp plates are made of heat-resistant ceramics. The electric heat generating device of the rotary evaporator is provided with the two electric heating blocks; the two electric heating blocks are not in direct contact with the body of the electric heat generating device and are fixedly connected with the body through the heat insulation clamp plates; a gap is formed between the heating blocks and the body, so that the body binding posts of the electric heating generating device are not influenced by high temperature, so that the service life of the electric heat generating device of the rotary evaporator is greatly prolonged.
Description
technical field [0001] The invention relates to an electric heat generating device, more precisely, an electric heat generating device for a rotary evaporator. Background technique [0002] Rotary evaporators are mainly used for concentration, crystallization, drying, separation and solvent recovery in pharmaceutical, chemical and biopharmaceutical industries. The principle is to heat at a constant temperature under vacuum conditions to make the rotary bottle rotate at a constant speed, and the material forms a large-area film on the bottle wall and evaporates efficiently. The solvent vapor is cooled by a high-efficiency glass condenser and recovered in the collection bottle, which greatly improves the evaporation efficiency. It is especially suitable for the concentration and purification of biological products that are easy to decompose and denature at high temperature. [0003] The electric heat generating device of the rotary evaporator needs to provide a long-term ele...
