Apparatus for processing fur animals

Description

The field of production

The present invention relates to an apparatus for processing fur. Background of production In connection with the processing of several types of fur animals such as e.g. mink skins, are used, after the fur, devices that scrape fat and other unwanted tissue from the inside of the fur.

The scraping typically takes place using scrapers which are brought into contact with the meat side of the fur animal skin. During the scraping process, each furry animal is usually clamped down on a judgment.

The dome is then inserted into a housing where scraping devices are provided configured to effect mechanical scraping of grease and other unwanted tissue from the meat side of the fur animal skin. The scraper devices are often designed as a rotary scraper driven by an electric motor.

EP 2,093,299 describes a method and apparatus for processing fur animals, wherein the fur animal skin is scraped for the purpose of removing unwanted fat and tissue from the meat side of the fur animal skin. The apparatus comprises an elongated judgment, a scraping device comprising one or more rotating scraping elements, means for displacing the judgment in its longitudinal direction, and a finishing unit with scraping elements slidable towards the judgment. The fur animal skin is placed on the elongated mandrel which is displaced along the scraper with rotating scraper elements which contact the fur side of the fur animal. After the scraping, the dom with the fur animal skin is passed through a finishing unit which also includes scraping elements which performs a further scraping.

2 2EN 2013 00007 U3 EP 2.093.299 does not describe the use of sawdust or other absorbent material.

It is known to sprinkle sawdust on the fur skin after the scraping process to absorb fat. DK150380B describes an apparatus for sprinkling sawdust on fur animals.

When fur skins are treated according to these described instructions, even after a subsequent drying process, a certain amount of residual fat in the fur skins is still present. The remaining amount of fat has a number of adverse effects on the fur animal skin. At worst, the remaining amount of fat causes some hair to fall off the coat. Therefore, it is desirable to reduce the amount of residual fat in the fur animal skin.

Purpose of creation

The object of the present invention is to provide an apparatus for removing and reducing the amount of residual fat in fur animals.

The object of the present invention is achieved with an apparatus as defined in claim 1. Preferred embodiments are defined in the subclaims and are explained in the following description and illustrated in the accompanying figures.

The apparatus of the invention is an apparatus for removing unwanted fat and tissue from the meat side of a fur animal skin, which apparatus comprises: - an elongated mandrel configured to support a fur animal skin thereon, with the meat side facing outward, - a scraping device comprising one or more rotating scraping elements configured to be contacted with the meat side of the fur animal skin to cure unwanted grease and tissue via scraping and, displaceable scraping elements configured to be brought into contact with the fur animal skin such that one or more of these scraping elements perform a further scraping. The apparatus comprises means adapted to the application of sawdust or other absorbent material to the fur animal skin prior to further scraping. The finishing unit comprises two first scraper elements with parallel oriented drive shafts, which scraper elements are configured to be offset in a direction normal to the dome, and a further third and a fourth scraper element, each having a drive shaft oriented perpendicular to the drive shafts for the first two scrap elements. where all the scraper elements are configured to be displaced in a direction normal to the dome.

This provides an apparatus that can significantly remove or reduce the amount of residual fat in the fur animal skin.

It is preferred that the scraper members be rotary and driven by an electric motor with a drive shaft on which the scrape members are rotatably mounted.

It is a great advantage if scraper elements are configured to be offset in a direction normal to the dome and that scraper elements are slidably mounted. Hereby it is possible to adjust the force by which the scraper elements against the judgment can be adjusted in relation to e.g. the thickness of the fur animal skin or the geometric shape of the dom, including its dimensions.

If the dome has a rectangular cross section, it would be advantageous to position the 25 rotatable scraper elements with parallel oriented drive shafts in such a way that the scraper elements are configured to be pressed against two of the dome's counter-oriented sides (e.g., two vertical faces) .

In a preferred embodiment of the apparatus, the orientation of each cabinet member is adapted to the geometric shape of the dome such that during operation the scraper elements operate substantially perpendicular to the side surfaces of the dome.

In a preferred embodiment of the apparatus, the finishing unit comprises a housing having a front face with an opening and a back side having an opening and the dome is configured to be passed through the openings and further through the finishing unit.

This ensures that the finishing unit can be retrofitted to existing cleaning machines.

In a preferred embodiment of the apparatus, the finishing unit comprises two scraper elements, each protected by a shield. The shield protects against foreign matter and is capable of absorbing fat and other tissue that is ingested from the meat side of the fur animal skin during the post-treatment process.

In a preferred embodiment of the apparatus, the scraper members are powered by electric motors and are configured to be displaced toward the dome and the apparatus comprises a control unit configured to adjust the force by which the scrape members are pressed against the dome.

This provides that the force by which the scraping elements are pressed against the dome can be adapted to meet special requirements (e.g., adjustments based on pelvic type characteristics, or adjustments due to changed judgment dimensions).
