Abstract

The invention discloses concentrating and drying equipment for producing L-prolinamide. The equipment comprises a tank body, wherein a driving motor is mounted at the bottom of the tank body through a bracket, an output shaft of the driving motor is connected with a cavity, the top of the cavity is connected with a liquid inlet pipe through a rotary joint, a plurality of liquid outlet pipes are arranged on the side wall of the cavity, a plurality of baffles are annularly distributed in the tank body and located on the outer side of the cavity, a confluence groove is formed in the bottom, located on the inner sides of the baffles, of the tank body, and a heater is installed at the bottom of the tank body. According to the concentrating and drying equipment, defects in the prior art can be overcome, and the concentrating and drying efficiency of L-prolinamide is improved.

Description

technical field [0001] The invention relates to the technical field of chemical equipment, in particular to a concentrated drying equipment for producing L-prolineamide. Background technique [0002] L-prolinamide is a kind of intermediate for the preparation of medicines for treating diabetes. At the end of the process for preparing L-prolinamide, it needs to be concentrated and dried to obtain high-purity L-prolinamide crystals. The existing drying equipment has low processing efficiency and poor drying temperature control accuracy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a kind of concentration and drying equipment for producing L-prolineamide, which can solve the deficiencies of the prior art and improve the concentration and drying efficiency of L-prolineamide. [0004] In order to solve the above technical problems, the technical solutions adopted by the present invention are as follows. [0005]...
