1、 Equipment Introduction
The CT-C hot air circulation oven adopts a high-temperature resistant circulation fan, and the forced hot air heated by electric heating tubes or steam heat exchangers circulates inside the oven, enhancing heat transfer, improving water evaporation rate, and shortening drying time. The entire box adopts a fully enclosed structure, with hot air circulating inside the box, effectively discharging humid and hot air and replenishing fresh air. The oven is equipped with an automatic temperature control system, ensuring precise temperature control.

The box is equipped with an adjustable air distribution plate, ensuring uniform temperature inside the box. Adopting a low-noise energy-saving built-in circulating fan, the operation is balanced and greatly reduces the noise and heat loss of the equipment. The air inlet is equipped with an air filter and comes standard with a dehumidification device.

The hot air circulation oven system mainly includes a cyclone separator, a blower, an air filter, and a heater The hot air coming out of the dryer is separated by a cyclone separator to remove powder and then returned to the blower. After filtration, it can be heated and sent into the dryer. During the circulation process, the temperature of the air is affected, and a portion of the circulating air is continuously discharged to supplement the fresh air that has been dehumidified and filtered. The characteristic of the dryer is that the slices are in the form of piston shaped comb balls in the ten dryer, which can basically ensure that the slices have a consistent residence time during the drying process, and the drying quality is good. Moreover, the dried slices can be continuously fed into the screw extruder hopper for spinning, avoiding moisture regain in the dried slices. The structure of the dryer itself is relatively simple

Operation process of two door four car hot air circulation oven

1. The hot air circulation oven should be used according to the temperature range specified on the nameplate, and the oven must be well grounded

2. Flammable items such as oil pans, oil drums, cotton yarn, and cloth scraps shall not be stacked near the oven, and washing, scraping, and painting work shall not be carried out near the oven

3. To prevent other objects from falling into contact with the resistance wire at the bottom of the oven and causing a short circuit

Before opening the oven, the power must be turned off first Do not leave during the heating process

5. Items such as tools, equipment parts, and volatile oils are not allowed to be stored in the oven

6. Parts that have been washed with flammable liquids such as gasoline, kerosene, alcohol, and banana oil, as well as items that have been painted, should be left at room temperature for 15-30 minutes. Only after most of the flammable liquids have evaporated can they be placed. 7. Bake in an oven and pay attention to ventilation indoors

8. The oven must not be cleaned during operation, let alone wiped with gasoline

9. Non metallic items must be heated in the oven according to the process specifications

Before operating the oven drying box, the ventilation gate must be opened to prevent explosion

11. Before use, check the self-control device, whether the indication signal is sensitive and effective, and whether the insulation of the electrical circuit is intact and reliable

The tuning steps for PID controller parameters are as follows:

Firstly, select a sufficiently short sampling period for the system to operate;

(2) Only add a proportional control loop until the system exhibits critical oscillation in response to the input step response, and record the proportional amplification factor and critical oscillation period at this time;

(3) Calculate the parameters of the PID controller through formulas under a certain degree of control
