The specific embodiment
Below with reference to Figure of description and specific embodiment the utility model is described in further details.
As Fig. 1, Fig. 2 and shown in Figure 3, the baking oven that the utility model is used for tunnel sterilizing and drying machine is mainly used in the high temperature section 15 of tunnel sterilizing and drying machine, and the front end of high temperature section 15 is a preheating section 13, and the rear end of high temperature section 15 is a cooling section 14.This baking oven comprises casing 1 and is installed in hot-air heater 2 in the casing 1, stream fan housing 3 looses, filter 4, transmit guipure 6 and temperature booster 11, diffusing stream fan housing 3 and filter 4 are arranged in the exit end of hot-air heater 2 and transmit between the guipure 6, form return air channel between the below of transmission guipure 6 and the temperature booster 11, medicine bottle 5 transmits through transmitting guipure 6, filter 4 is a high temperature high efficiency particulate air filter 4, offer wind-supplying mouth 9 and dehumidifier exhaust outlet 7 on the casing 1 in the return air channel place, wind-supplying mouth 9 is connected with secondary air channel 10, dehumidifier exhaust outlet 7 links to each other with exhausting hydrofuge machine 12 through dehumidifier exhaust duct 8, and exhausting hydrofuge machine 12 is used to provide the power of discharging hot and humid air.On the dehumidifier exhaust duct 8 one section or dehumidifier exhaust duct 8 all are sheathed in the secondary air channel 10, one section of dehumidifier exhaust duct 8 middle parts is sheathed in the secondary air channel 10 in the present embodiment, can make like this dehumidifier exhaust fan 12 away from high temperature section 15 in order to avoid damage, and guarantee good heat exchange effect; The part that dehumidifier exhaust duct 8 is located in the secondary air channel 10 should be positioned as close to dehumidifier exhaust outlet 7.Wind-supplying mouth 9 is positioned on the sidewall of casing 1, and dehumidifier exhaust outlet 7 is positioned at the bottom of casing 1.
