EXAMPLE 1 A garbage compartment having a depth of 50 mm, a width of 240 mm, and a depth of 2 was placed in a garbage compartment partitioned by walls having air flow ports at the upper and lower portions.
Seven 70 mm garbage containers are arranged vertically in seven stages, and a dehumidifier (cooling capacity 250 kca) is placed in the dry air production room on the opposite side of the wall.
1 / h, air volume 8m ³ / h), height 525m
Seven garbage containers containing garbage are vertically arranged in a garbage chamber of a garbage drying apparatus having a length of 580 mm and a width of 580 mm and a depth of 36 mm. Next, the switch to the drying device is turned on and the dehumidifier is operated. The dry air dehumidified by the dehumidifier enters the garbage chamber through a circulation port at the upper part of the wall provided between the dry air production chamber and the garbage chamber, passes through the uppermost garbage container, and sequentially enters the garbage container. After passing through the lower garbage container, it reaches the lowermost garbage container, returns to the dry air production chamber from the distribution port provided at the lower part of the wall, and is dehumidified by the dehumidifier.
The dehumidified and dried air enters the garbage chamber again through the circulation port at the top of the wall, and repeats the drying of the garbage. The garbage container thus dehumidified is taken out from the garbage discharge port by opening the lid of the discharge port of the garbage chamber. At this time, each garbage is sequentially moved to the upper stage one by one by a lift. A new garbage container containing 1.1 kg of garbage is put into the bottom row from the garbage entrance at the bottom of the garbage compartment of the garbage drying device. 110 g of the garbage sequentially dried in this way is taken out from the upper garbage carry-out port, and new garbage is put in from the lower garbage carry-in port. The water content of the garbage treated by this garbage drying apparatus was reduced to 0.8%, and was 1/10 of the weight when the garbage was carried. The volume was 1/20. Note that the degree of drying can be appropriately changed as needed. The dry garbage is odorless and its volume is reduced by a factor of 20, so that the amount of household garbage is small and does not need to be removed 2-3 times a week as before. Further, similarly, the dried air may be introduced from the lower distribution port and returned to the dry air production chamber from the upper distribution port to be dried.
Further, drying may be performed by introducing dried air through the distribution ports provided at five places on the wall and returning the dried air to the dry air production chamber through the other five distribution ports. When deodorization of air containing water from garbage is performed using 4pgm6 (Institute of Industrial Science and Technology, Institute of Biotechnology, Accession No. FERM P-17867), after 24 hours, many odor components are decomposed and odors are decomposed. Was decreasing. After 48 hours, no odor was felt.

[0018]

In addition, it gives priority to the movement of moisture and dries without applying heat by a dehumidifier, so that only free water can be actively used without sacrificing the high quality and high functionality of garbage. Can be removed. As a result, the dried garbage can be used as feed, organic fertilizer, and the like. Since it can be dried at room temperature, it can be economically processed and there is no danger of fire, explosion and the like. The garbage deodorizing apparatus of the invention of the present application does not generate odor with the processing of garbage, and therefore, it is not necessary to treat the odor, so that it is applied from home use to large-scale garbage processing facilities. It can easily process garbage at home without disturbing others. In addition, this garbage drying device is free of pollution to nature because only the removed water flows out of the device, and especially in the vicinity of mountains, lakes, marshes, rivers, etc., where protection of nature is required. Even better effects can be exhibited in facilities. Since the space is sealed, there is no spoilage due to microorganisms, and generation of odor and contamination due to spoilage can be prevented.
In addition, the generation of offensive odors due to putrefaction can be suppressed by efficiently dehumidifying and drying free water related to putrefaction in food at normal temperature. Although there is a problem with the amount of garbage in the amount, there is an excellent effect that the amount of garbage can be reduced to 1/4 to 1/50 by the present invention.
