ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to drying machines and more particularly to a drying machine adapted to dry meat and equivalents.
Previously, meat was dried under sunshine or baked by fire or drying oven. A large sized drying machine not only effectively dries large batch of meat, but also keeps it delicious.
Typical large sized drying machine as shown in
FIG. 1
comprises a housing
10
, heaters
11
disposing on two sides covered by conductive partitions
12
, a meter
13
operating a fan
14
on the top to exhaust the moisture from inside the housing
10
through a pair of air vents
101
. The housing
10
further has a plurality of air vent
102
in lateral walls and the partitions
12
has a plurality of conductive plate
121
toward the heaters
11
. The meats dispose inside the housing
10
. When the door
15
is closed and the machine is operated, the heating elements will provide proper heat to dry the meat, meanwhile the fan exhausts the vapor from the meat in order to enhance the drying effect.
However, this type of drying machine has the disadvantages set forth as follows:
a) can not exhaust all the vapor from housing,
b) a great deal of hot air exhausts out of the housing via the air vent
101
wasting of the energy and elongate the drying time,
c) the heaters together with the fan cant not form a proper air circulation inside the housing, and
d) lack of the seasoning entrance to dispose the seasoning container so that each time when replenishes the seasoning must open the front door to break the drying process so as to cans effectiveness.
SUMMARY OF THE PRESENT INVENTION
The present invention has a main object to provide a drying machine which has a heat exchanger on the top to form a proper air circulation to absorb the vapor inside the housing in order to intensify the drying process.
Another object of the present invention is to provide a drying machine which has a plurality of seasoning entrances to facilitate the replenishment of the seasoning containers without breaking the drying process.
Still another object of the present invention is to provide a drying machine which has a control panel on front side to control the operations of the elements, the temperature and the humidity inside the housing so as to ensure that the dried meat to be delicious.
