How to feed easily crystallizing materials into a kettle with a cooling jacket?

The entire reactor vessel is cooled over night, and the feeding port is also equipped with electric heating and kept active throughout the night. I was wondering if anyone who’s encountered this situation has any suggestions for a better type of feeding port that can prevent clogging or ensure smooth feeding each time. I’d really appreciate some advice from those who know more!
Is there no one who can give some advice? I’ll take care of it myself.
Is there anyone who can offer some advice?
Hasn’t everyone encountered this problem, or did I post in the wrong forum?
I’m a bit confused by the terms ‘cooling over night’ and ‘electric heating over night’ mentioned by the poster, but I roughly understand what they mean. The diameter of the feeding port can be increased appropriately (it should be larger than that of the feed pipe, and connected using non-standard flanges). Heat tracing is added outside the feed inlet.
3 methods: 1. Install a preheater with a structure similar to that of a condenser at the feeding port. 2. Use a jacketed flange at the feeding port, with hot water or steam used inside the jacket. 3. Place a heating internal coil inside the reactor; choose one of these methods depending on the characteristics of your reactor and the materials being processed
Thank you for the reply; the opening has been tightly sealed and coated on the inside. It can’t be increased.
A small heater is placed above the opening; once the material melts, it flows into the tank
Thanks for the advice; I’m working on it now.
The plan is more or less ready; it’s okay
