The purpose of the silkworm cocoon drying process is to dry the larvae of the cocoon and the parasitic flies, prevent the emergence of aphids and moths, and at the same time remove the appropriate amount of water to prevent mold deterioration, which is more favorable for storage. The use of temperature and humidity recorders for timely detection of temperature and humidity control in the silkworm cocoon drying process is crucial. The temperature is just right and the sericite degeneration of the silica gel layer is very significant. The quality of raw silk has a significant relationship with silk production and economic efficiency.
For example, if the temperature and humidity recorder finds that the drying temperature is too high, the bismuth layer will be dry, and not only the sericin will be denatured and the yellow color will be formed, but also the bismuth layer will be deteriorated, affecting the silk. The effect of humidity on the performance of silk reels is combined with factors such as temperature and air flow. It can neither be too high nor too low. The high temperature and humidity will make the sericin degeneration and increase the binding force, which will reduce the solubility of the sericin; at high temperature and low humidity, due to the influence of heat on the tantalum wire, the spasticity of the sputum will become poor.
Therefore, through the temperature and humidity recorder to understand the continuous change of temperature and humidity in the baking process, to provide a favorable basis for the drying temperature and humidity control and control, has been the demand for silk manufacturing enterprises. The outside of the polyester fiber tube is a vacuum insulation tube 7, and a layer of tin foil paper is applied on the outer surface of the polyester tube and the inner surface of the heat insulation tube, which can reduce the heat radiation; the polyester tube and the heat insulation are tightened after the cover of the insulation tube is tightened. The gaps between the cylinders form a closed air layer that reduces heat transfer.
These measures make the electronic components on the circuit board in the temperature and humidity recorder unable to measure the high temperature external environment and affect the normal operation. The shell is made of stainless steel and can be rolled in the measurement. The temperature and humidity recorder is perfectly suitable for the measurement of the drying conditions. When the value of the measurement of the instrument is transmitted and linked through a certain communication interface, the measured value can be saved.
