Method for debristling animal skin
View Patent ↗A variety of compositions and methods for removing hair from animal skin are disclosed. The methods can include heating the skin and applying force to the skin to remove hair. The methods can further include applying an adhesive comprising a wax and a resin to the skin, allowing the adhesive to solidify, and applying force to the adhesive.
1. A device for removing hair or bristles from an animal skin, comprising:
a chamber configured to hold a heatable liquid and to hold an animal body;
means for applying friction to skin of the animal body in an area of the skin containing hair or bristle to remove the hair or bristle from the skin,
means for heating and controlling the temperature of the liquid in a temperature range that allows the hair or bristle to be removed by friction, but has a maximum temperature and heating time that does not damage a dermal extracellular matrix of the skin, wherein the means for heating and controlling the temperature is configured to maintain the temperature between about 53° C. and about 56° C.; and
at least one support for holding the animal body.
2. The device of claim 1 , wherein the means for heating and controlling the temperatures is configured to maintain the temperature at about 54° C.
3. The device of claim 1 , wherein the means for heating and controlling the temperature is configured to maintain the temperature below 60° C.
4. The device of claim 1 , wherein the liquid comprises water.
5. The device of claim 1 , further comprising means for rotating the animal body.
6. The device of claim 1 , wherein the means for applying friction comprises a group of roller bodies.
7. The device of claim 1 , wherein the means for heating and controlling the temperature includes at least one heater and a feedback mechanism.
8. The device of claim 1 , wherein the chamber is sized to receive a pig animal body.
9. The device of claim 1 , wherein the at least one support is positioned such that an animal body placed on the support will be submerged within a liquid in the chamber.
10. A device for removing hair or bristles from an animal skin, comprising:
a chamber configured to hold a heatable liquid and to hold an animal body;
means for applying friction to skin of the animal body in an area of the skin containing hair or bristle to remove the hair or bristle from the skin,
a heater for heating the liquid to a temperature between about 53° C. and about 56° C.; and
at least one support for holding the animal body.
11. The device of claim 10 , wherein the liquid comprises water.
12. The device of claim 10 , further comprising means for rotating the animal body.
13. The device of claim 10 , wherein the means for applying friction comprises a group of roller bodies.
14. The device of claim 10 , further including a feedback mechanism operatively engaged with the heater.
15. The device of claim 10 , wherein the chamber is sized to receive a pig animal body.
