Preparation equipment for high-quality down feather and method thereof

Abstract

The invention provides preparation equipment for high-quality down feather and method thereof. The preparation equipment comprises a dehydrator and a cooling dust remover, as well as a double-layered washing machine including both an upper layer washing machine box body and a lower layer washing machine box body, and further comprises a dryer with a steam pipeline inserted therein, wherein a plurality of steam holes are formed in the steam pipeline. The preparation method comprises the following steps: (1) washing in the upper layer; (2) washing in the lower layer; (3) dehydrating; (4) drying; and (5) cooling and removing dust. According to the invention, as the washing machines in the upper and the lower layers are adopted for washing, the cleanliness of down feather is improved; as the dryer adopts the steam and stuffy drying manners in the drying process, sulfurous acid in feathers can be quickly reduced to bacillus for killing, and secondary pollution is avoided; and 100KG raw materials can be washed in only 85 minutes, and the weight productivity within 12 hours can reach 750KG, so that the production efficiency is high.

Description

technical field [0001] The invention belongs to down preparation equipment and a preparation method thereof, in particular to a high-quality down preparation equipment and a method thereof. Background technique [0002] The four major microorganisms that are required to be tested in the down standard - mesophilic aerobic bacteria, streptococcus faecalis, sulfite-reducing bacillus and salmonella. Our country stipulates the limit requirements of four kinds of bacteria in down filling materials. The standard stipulates that when the oxygen consumption exceeds 10mg / 100g, microbial detection is required. The four kinds of microorganisms stipulated in the standard are not resistant to high temperature. Can be inactivated, sulfite-reducing Bacillus can be completely inactivated under high temperature conditions of 120°C for 20 minutes, so high-temperature sterilization in a dryer is usually used for sterilization. After many years of working practice in the laboratory, it was foun...

Problems solved by technology

After many years of working practice in the laboratory, it was found that the most commonly detected bacteria in the experiment were sulfite-reducing bacillus. The reason is that the inactivation of sulfite-reducing bacillus requires a higher temperature. Incomplete bacillus inactivation

Due to the improvement of living standards, people's requirements for down products are getting higher and higher. The original production line needs about 160 minutes to wash 100KG feathers with water. The washing time is long and the production efficiency is low. It is easy to cause secondary pollution in the
