Product Introduction
The Innohx TW series scraped surface heat exchanger is a vertical
double jacket structure, with an outer insulation layer and heating or
cooling media passing through the inner and outer jacket layers. The
product is fed from the bottom of the heat exchanger and discharged
from the top. The bottom motor drives the scraper cage to rotate, and
multiple scrapers scrape the product off the inner and outer cylinder
walls. This ensures that heat sensitive materials, high viscosity materials, high solid content materials, and materials containing large particles will not be affected by heating and cooling processes, improving mass and heat transfer efficiency, avoiding wall sticking and particle damage, and fully realizing continuous heating or cooling processes, ensuring high quality and consistency of the final product.
