Description

Technical Field

[0001] This utility model relates to the field of concentration equipment, and in particular to a vertical heater. Background Technology

[0002] A concentrator is a piece of equipment used in the concentration processes of traditional Chinese medicine, health products, natural flavorings, food additives, food, and chemicals industries. Since its invention, the concentrator has been widely used in many fields such as chemical industry, pharmaceutical production and processing industry, mineral processing industry, and wastewater treatment.

[0003] In multi-effect evaporators, external heaters are a common design optimization.
