Abstract

The invention discloses a system for rapidly removing down and hair roots of duck bodies. The system comprises an alkaline water pool, a dehairing shaft roller assembly and a saline water spray assembly, wherein the alkaline water pool is internally filled with alkaline water, and the concentration of sodium hydroxide in the alkaline water is 10-12%; the alkaline water pool is used for soaking pre-dehaired duck bodies; the dehairing shaft roller assembly comprises two shaft rollers rotating along the opposite directions, and is used for squeezing and rubbing the duck bodies subjected to alkaline water soaking; the saline water spray assembly comprises a spray nozzle, and saline water can be sprayed out from the spray nozzle; the duck bodies, which are squeezed and rubbed by the shaft rollers, can be cleaned and preserved by means of the sprayed saline water. The invention also discloses a method for rapidly removing the down and the hair roots of the duck bodies. The system and the method for rapidly removing the down and the hair roots of the duck bodies are rapid in speed, time-saving, labor-saving, non-toxic, harmless and thorough in hair removal, and also improve the brightnessof meat.

Description

technical field [0001] The invention relates to a hair removal machine, in particular to a system and method for quickly removing white-striped duck down and hair roots. Background technique [0002] The fact that chicken feathers are easy to pluck but duck feathers are difficult to remove is well known. This is because there is a layer of waterproof fat on the duck feathers, which cannot be wetted by water; there is a thick layer of fat under the duck skin, and the roots of duck hairs are very deep.

Therefore, the hair removal machines on the market can remove chicken feathers, but not duck feathers. In order to effectively remove feathers from ducks, some slaughtering sites and operating individuals use industrial rosin and asphalt repeatedly for long-term depilation. Industrial rosin contains fatty acid, benzene compound, lead and other subs...

Problems solved by technology

[0004] Currently, the hair removal machines used in duck slaughtering plants can only remove the large hairs of ducks. The white striped ducks coming out of the slaughtering factory always have fluff and some hair roots. Before the finished product is processed, the customer must manually remove the fluff with clips. It is time-consuming and labor-intensive to remove the root and hair root. If it is not removed, it will affect the appearance of the finished product and people's appetite, and seriously affect the quality of the product.
