Overview

The durable temperature control module of the high-temperature blast drying oven adopts a microcomputer PID controller, supports multi-stage program programming, and can accurately set the temperature curve and display data in real time. Some models are equipped with independent temperature limiting protection systems, which automatically interrupt heating when the temperature exceeds the set value to ensure experimental safety.

Product Details

High temperature blast drying oven is durable and long-lastingIt is an industrial equipment that achieves high temperature environment control through forced hot air circulation. The core structure includes a box, a heating system, a blower device, and an intelligent temperature control module. The box adopts a double-layer steel plate design, with the inner layer made of corrosion-resistant stainless steel material and the outer layer treated with anti rust spray coating; Fill the middle with insulation material to reduce heat loss. Heating systems are usually composed of electric heating tubes or far-infrared radiators, combined with high-temperature resistant fans to form forced convection circulation, ensuring uniform temperature distribution inside the box. The temperature control module adopts a microcomputer PID controller, which supports multi-stage program programming and can accurately set the temperature curve and display data in real time. Some models are equipped with independent temperature limiting protection systems, which automatically interrupt heating when the temperature exceeds the set value to ensure experimental safety.

High temperature blast drying oven is durable and long-lastingImprovement methods for temperature uniformity:

1. Determine the * position of the heater:

Whether the heat emitted by the heater can be evenly carried into the working chamber by the airflow is the key to ensuring the temperature uniformity inside the box working chamber. Therefore, determining the position of the heater is extremely important. After multiple repeated experiments, we finally determined the ideal position of the heater, which effectively improved the technical indicators inside the box.

2. Improve the airflow organization structure of the high-temperature blast drying oven:

The quality of the "temperature uniformity" indicator of the drying oven mainly depends on the airflow organization structure. Drying ovens usually use a single air duct structure to organize airflow, which mainly comes from the centrifugal fan system. In this structure, the design of the centrifugal machine casing and the design of the air guide plate are the key factors determining the indicators. Therefore, we first redesigned the snail shell strictly according to the Archimedes' spiral principle. Enable the airflow from the volute outlet to blow evenly through the heater, ensuring even air supply. In addition, we have made corresponding improvements to the air outlet and return outlet of the air guide plate, increasing the air volume of the return outlet as much as possible, while increasing the air pressure and speed of the outlet. Enable the airflow to circulate evenly within the workspace.

3. Improve the locking device of the gate:

High temperature blast drying ovens with temperatures of 400 degrees and above can cause significant deformation of materials when heated due to their high temperature. In the past, the door of the high-temperature blast drying oven was locked with a single point. However, at temperatures above 400 degrees Celsius, the deformation of the door resulted in poor sealing between the door and the box, causing the door to leak heat. The temperature inside the box chamber near the door was too low, affecting the uniformity index inside the box. We have changed the gate to double point locking, which has effectively solved this problem. By improving the "temperature uniformity" index of drying ovens at 400 degrees and above, we have gained a lot of inspiration and accumulated some experience. I believe this will have a certain impact on the redesign of our drying oven in the future.

4. Improve the sample shelf:

The single duct airflow structure dictates that the airflow must pass through the sample shelf. A typical drying oven has at least two shelves, and those with special requirements may even have more. In the past, shelves were made by punching and bending plates. But in order to ensure its strength, the aperture density of the shelf cannot be too high, which leads to excessive resistance to airflow circulation and affects the uniformity of temperature from the surface. We changed the shelf to a steel wire structure, which effectively solved this problem.
