Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for drying and removing hair removal from tanned fur leather that has been dehydrated using a centrifugal dehydrator or the like.

Conventionally, tanned fur leather is dehydrated using a centrifugal dehydrator, etc., and then placed into a rotating drum, hot air is supplied, and hot air drying is performed. However, this hot air is 60 to 100
Because the temperature is relatively high, the shrinkage rate of fur leather is also high, and it has the disadvantage of giving a stiff feel.

In view of this, the present invention rotates a drum containing pre-dehydrated fur leather in a casing so that the fur leather is kneaded by the partition plate in the drum and the fur leather. After dehumidifying the air with a dehumidifier and circulating it through a duct equipped with a dust collector, and removing hair loss, dust, etc. contained in this circulating air with a dust collector, the casing and the massaging drum inside the casing are removed. The gist of this is that the system was designed to allow circulation within the country.

The invention will be described below based on illustrated embodiments.

In the figure, 1 is a closed casing, and inside this casing 1 is a kneading drum 2 of a required size with the outer circumferential surface and side surfaces or only the outer circumferential surface meshed to improve air circulation. The kneading drum is rotatably provided, and a large number of partition plates are provided on the inner peripheral surface of the kneading drum so that a kneading action is performed when the furs and leather placed in the drum are moved and dropped by the rotation of the drum. A circulation duct 3 is provided in the casing 1 to circulate drying air, and one end of the duct 3 is placed at a position for supplying drying air into the casing 1, and the other end is placed at a position at the exhaust port of the casing. At the same time, a dust collector 4 is provided in the circulation duct 3, and a dehumidifier 5 is provided in the casing. Of course, a circulation fan is provided within the duct or the casing to circulate air within the casing and the duct.

Then, the required amount of tanned fur leather is put into the rotating kneading drum 2 inside the casing (through the intake port with a door provided on the outer circumferential surface or side surface of the kneading drum 2), and while the kneading drum 2 is rotated, the inside of the casing is By dehumidifying air with a dehumidifier installed in the casing and circulating it through a duct, the fur leather in the kneading drum is kneaded and loosened by the rotation of the drum and the action of the partition plate. Since the drum has a net shape, the air flowing inside the casing also enters and flows inside the kneading drum, thereby dehumidifying the fur leather. Then, when the drum passes through the casing and duct to reach the dust collector, the dust mixed in with the fur leather and the hair loss that occurs during drying are removed by this dust collector, and then again through the duct. The air is returned to the casing, and in this way, the air is circulated within the casing, drum, and duct to perform the desired kneading action while drying, and also to remove dust such as hair removal.

In addition, the dehumidifier installed in the middle of the duct not only dehumidifies, but also heats the fur to a relatively low temperature suitable for drying without causing it to contract or become hard. When using a refrigerating machine, if the evaporator and condenser are not invented, a rotating kneading drum filled with fur and leather is housed in a casing along with a dehumidifier, and the inside of the casing and drum are dehumidified and dusted. Because the dry air is circulated, the fur leather is softened by an appropriate kneading action, and the relatively low-temperature dehumidified air can be used to dry the fur leather without impairing its quality. At the same time, it also removes hair and dust. It has the advantage of being easy to perform.

Claims (1)

[Claims] A dehumidifier and a rotatable drum are installed inside the sealed casing, and a duct is connected to the casing to circulate the dust-removed dry air.This air flow is circulated inside the drum to massage and loosen the fur inside the drum. This method dehumidifies and dries the circulating air inside the casing while applying the action to dry and remove hair from the inner leather of the casing 1.
