The utility model relates to the technical field of poultry slaughtering, and discloses a high-temperature scalding device for feather treatment in poultry slaughtering, which comprises a scalding box body, a scalding frame is movably sleeved above the inner part of the scalding box body, a push plate is slidably arranged on the left side of the inner part of the scalding frame, a first fixing block is fixedly arranged on the left side of the top of the scalding box body, and a second fixing block is fixedly arranged on the right side of the top of the scalding box body. A first low-speed motor is fixedly mounted on the right side of the first fixing block. According to the scalding device, the scalding frame can be conveniently driven to vertically move, the scalding frame can be moved to the upper portion of the interior of the scalding box body, and at the moment, through cooperation of a first fixing block, a first low-speed motor, a first lead screw, a second fixing block and a guide rod, a push plate can be conveniently driven to horizontally move in the scalding frame; the poultry in the scalding frame can be pushed to one side of the upper portion of the scalding box body and slide downwards through the inclined protective cover, the scalded poultry can be conveniently and rapidly taken out through the mode, and therefore the time and energy of workers for manually collecting the poultry are saved.

This invention discloses a highly efficient serine protease for degrading β-keratin, its degradation method, and its applications. The serine protease is named LteKerS, and its amino acid sequence is shown in SEQ ID No. 2, while the corresponding coding gene sequence is shown in SEQ ID No. 1. The amino acid sequence of the recombinant serine protease rLteKerS, which has its N-terminal signal peptide removed and has a purification tag at its C-terminus, is shown in SEQ ID No. 4, while the corresponding coding gene sequence is shown in SEQ ID No. 3. The recombinant serine protease rLteKerS can efficiently degrade β-keratin under alkaline conditions, directly acting on intact feathers. The reaction conditions are mild, requiring no high temperature, high pressure, or complex pretreatment. The degradation products are soluble proteins and peptides, which can be used as high-value-added amino acid raw materials, functional peptide raw materials, biodegradable materials, bio-based material precursors, bio-feed proteins, fertilizers, etc. It is suitable for the large-scale processing of by-products such as poultry feathers and has good industrial application prospects.

This utility model discloses an automatic continuous poultry defecation machine, relating to the technical field of poultry processing equipment. It includes a base box, with a defecation cylinder rotatably mounted on its upper end. Multiple sets of defecation rods are arranged inside the defecation cylinder. A cleaning mechanism is provided at one end of the base box for cleaning the defecation cylinder and the multiple sets of defecation rods. A quick-release mechanism is provided on the outer wall of the defecation cylinder. The quick-release mechanism includes multiple sets of circular seats, each with a circular rod inserted inside. A circular ring seat is fixedly installed inside each of the circular seats. Vertical holes are drilled through one end of each of the circular seats and the circular ring seat. Two sets of top blocks are welded to the outer wall of each of the multiple sets of circular rods. This utility model allows the circular rods to be quickly removed from the circular seats, enabling operators to disassemble the defecation rods quickly without complicated disassembly steps. This facilitates cleaning of the defecation rods, significantly saving cleaning time and labor costs, and improving production efficiency.
