Quality of product being dried depends on the time and amount of heat they are exposed to; heating temperature plays a crucial role in the overall development of products within the oven, hence stable temperature is key to success here. Temperature uniformity doesn’t only mean maintaining the same temperature across but it means having the desired temperature across every section of the oven with the same consistency throughout its operational time.
How can we achieve this consistency? The answer is very simple just by reducing the temperature fluctuation but the implementation of the same is complex. One of the ways to reduce this fluctuation is reducing temperature losses by using proper insulation of the chamber using reliable material and methods. Continuously monitoring and controlling is key for the implementation of the dryer with uniform temperature.
Kerone’s dryer is built with superior quality materials with cautiously taking care of each and every required measure; secondly, all dryers are fitted with an intelligent feedback loop with various sensors fitted at different sections for monitoring these measured temperatures are fed to correction unit; this correction unit compares the deviation and accordingly decides to increase or decrease firing to maintain the ultimate temperature stable. Kerone implements even really complex control mechanisms as well based on the customer’s process and product requirements.
Uniformity with Temperature brings in various advantages:
Consistent Product Quality:
Maintaining minimum temperature deviation ensures every piece of the product is treated with the same temperature hence quality will be the same, also too much deflection in drying temperature sometimes results in compromised product quality. Heat sensitive materials might result in a lot of wastage.
No or less re-processing:
If we fail to maintain uniformity it might result that some materials are not processed as desired and this might require refeeding for processing. Many heat-sensitive materials will not allow this as well.
Fewer Losses and Wastage:
Materials treated in uniform temperature always attain better quality, however fluctuating temperature results in too hot and too cold-processed material when you try reprocessing them they over dry and loose its effectiveness, quality and result in unusable and results in the increase of waste.
How to maintain uniform temperature:
There are multiple ways to attain uniform temperature across oven, insulating is one of them:
Controlled Air Flow:
The volume and direction of airflow inside an oven influence the temperature consistency. A high volume of air is alluring, as the higher the volume, the better the warmth consistency. In a perfect world, airflow inside a stove arrives at all pieces of the oven similarly. This airflow can be either horizontal or vertical however should be steady to continue a steady temperature.
Insulated walls to minimize losses:
An oven’s insulation shifts in thickness as indicated by the oven’s temperature and consistency prerequisites. Additionally, utilizing extraordinary boards and unitized development decreases an oven’s through-metal warmth misfortune, adding to more prominent warmth consistency.
Appropriately positioned openings help keep up positive air pressure inside an oven, decreasing the danger of cool air leaking through the entryway seals. Before entering the work chamber, new, cool air should go through heating components and blend in with hotter, recycled air. This blending forestalls layers of various temperatures inside an oven.
