Description

Door assembly and hermetic pressurization apparatus including the same

The present invention relates to a door assembly and a hermetic pressurization apparatus including the same. More specifically, the present invention relates to a door assembly and a closed pressurization apparatus including the same, which can prevent an overload that may occur in the pressurization device by detecting a lifting of the door by the pressure generated in the pressurization device.

Food waste is discharged every day from homes and restaurants, but most of the waste is filtered and then disposed of. Since this increases the amount of garbage and causes odors to pollute the surrounding air, efforts have recently been made to reduce food waste at homes and restaurants. As one of these efforts, a food processor is widely used.

One of the goals of the food processor is to reduce the volume of food that is processed and discharged. Since water takes up a large portion of the food volume, the volume of food discharged to the outside is drastically reduced. Most of the water removed is contained in the off-gases.

Therefore, the pulverized dry food processor, which is one of the most widely used food processor, includes a drying furnace in which food is crushed and dried, and a high-temperature exhaust gas containing a large number of odors and moisture generated during food processing in the drying furnace. And a moisture absorption filter and a deodorization filter which are disposed on the discharge path and are disposed on the discharge path to remove moisture and odor of the discharge gas. The filtered gas is discharged to the atmosphere outside the food processor.

The filter used in the food processor is a consumable and needs to be replaced periodically. If the replacement is not made on time, there is a problem in that the odor component is discharged to the outside air.

As one of the other types of food processor that can solve this, there is a circulating food processor that recycles inside the food processor without releasing the discharge gas to the outside. The circulation type food processor has a big advantage that a filter is not required because the exhaust gas is recycled without being discharged to the outside.

However, since the odorous exhaust gas stays inside the food processor as the opposite benefit, a tight seal is required for each space communicating with the outside in order to prevent the odor from being discharged to the outside.

As described above, the sealing of the food processor requires a tight sealing between the door assembly and the drying furnace disposed on the food processor to enable food waste input.

On the other hand, the door assembly constituting the conventional food processor has a structure that detects only the opening or closing of the door, the drying furnace due to the excessive amount of food in the drying furnace or steam generated during the drying process during the grinding process There is no way to cope with the case of forming a vapor pressure higher than the limit in the product is often a defect occurs.
