On the installation of hot press and the supplement of temperature

The inner part of the hot press needs to process many channels. After sealing and welding, a specific form of circuit is formed to heat the hot pressed plate and blank by saturated steam.

The installation of hot pressing plate should be opposite to the installation: the steam inlet and outlet configuration of two adjacent hot pressing plates in the partial hot pressing device of single plate hot press is opposite. The high and low temperature zones of two adjacent hot pressing plates can compensate each other, which is helpful for the uniform heating of the blank. Whether the loop form of heating channel of hot pressing plate is reasonable or not plays an important role in improving the performance of hot pressing and shortening the hot pressing time. The hot press plate surface temperature difference is small, and the product quality is good, which can reduce the strength of the hot press plate stiffness and strength weakening caused by drilling, and reduce the circulation resistance of the fruit body in the channel. The hot pressed plate is easy to block, the temperature difference between the plate surface is large, the heat of the product is uneven, and the water content is not good everywhere. In this way, the strength will be affected and the yield will be reduced by prolonging the hot pressing time.
