In addition, the heat recovery module of the present invention recovers sensible heat and latent heat in the exhaust gas discharged from the drying box by the total heat exchanger. Because of the inside formaldehyde that often contains the high concentration of panel, formaldehyde is very fast under the environment of high temperature and high humidity, therefore the stoving in-process, the inside formaldehyde concentration of stoving case is higher, if want to reach the effect of cleaing away this part formaldehyde, needs the exhaust in the stoving case, introduces fresh air. However, the exhaust gas in the drying box has high heat, and if the exhaust gas is directly exhausted to the air, the energy is wasted. Therefore, the heat recovery device is arranged and used for recovering sensible heat and latent heat of the part of waste gas and preheating the part of waste gas for fresh air, so that the energy utilization efficiency can be effectively improved, the aim of saving energy is fulfilled, and the effect of removing formaldehyde is achieved.
