Description

Technical Field

[0001] The invention relates to the technical field of enzymatic processing, in particular to a rapid enzymatic hydrolysis device for by-products of livestock product processing. Background Art

[0002] A large amount of by-products are left over during the processing of livestock products, such as organs or scraps such as liver, lungs, spleen, and small intestine. These by-products are rich in protein and other nutrients and have extremely high utilization value. Traditionally, these by-products are often disposed of by landfill or direct dumping, which not only wastes precious resources but also may cause serious pollution to the environment. With the enhancement of environmental awareness and the advancement of technology, how to efficiently develop and utilize these by-products has become an important research direction.

[0003] The comprehensive utilization of livestock processing by-products refers to the process of using these by-products as raw materials and developing them using reasonable modern processing technologies based on their characteristics, nutritional content and processing characteristics. In particular, the application of enzymatic hydrolysis technology has attracted widespread attention because it can effectively decompose complex proteins into small molecule peptides and amino acids that are more easily absorbed. Compared with traditional treatment methods, enzymatic hydrolysis can not only effectively solve environmental pollution problems, but also create additional economic value.

[0004] Existing enzymatic hydrolysis technology mainly adopts a static enzymatic hydrolysis method, that is, by-products are added one by one into the enzymatic hydrolysis tank for treatment, and the products are taken out one by one after the enzymatic hydrolysis is completed, which makes the whole process more cumbersome and affects work efficiency. Moreover, under static conditions, some parts of the by-products may not be fully exposed to the enzyme, thus limiting the thoroughness and efficiency of the enzymatic hydrolysis reaction. Summary of the invention

[0005] The purpose of the present invention is to provide a rapid enzymatic hydrolysis device for livestock product processing by-products, which adopts a dynamic enzymatic hydrolysis method to continuously enzymatically hydrolyze the by-products, with higher working efficiency, and can continuously stir during the enzymatic hydrolysis process, which is more conducive to efficient enzymatic hydrolysis.

[0006] The above technical purpose of the present invention is achieved through the following technical solutions: a rapid enzymolysis device for livestock product processing by-products, comprising an enzymolysis pool, the enzymolysis pool is divided into a plurality of enzymolysis chambers distributed side by side by vertical partitions, each vertical partition is provided with a horizontally arranged strip-shaped connecting groove for connecting two enzymolysis chambers, the tail end of the enzymolysis pool is provided with a horizontally arranged strip-shaped discharge groove connected to the enzymolysis chamber at the tail end, each enzymolysis chamber is rotatably connected with a constant temperature rotary drum, each constant temperature rotary drum comprises an inner drum located inside and an outer sleeve covering the inner drum, a driving motor for driving the constant temperature rotary drum to rotate is installed outside the enzymolysis pool, and a plurality of stirring push pieces are arranged outwardly on the periphery of each outer sleeve;

A rotating inlet pipe and a rotating outlet pipe connected to the corresponding convergence cavity are respectively provided outwardly at both ends of each constant temperature rotary cylinder. The enzymolysis pool is respectively provided with a horizontal heat pipe and a horizontal cold pipe at both ends of the constant temperature rotary cylinder. The horizontal heat pipe is connected to a plurality of inlet sleeves distributed along its length direction and sealed and rotatably connected to the rotating inlet pipe in a one-to-one correspondence. The horizontal cold pipe is connected to a plurality of outlet sleeves distributed along its length direction and sealed and rotatably connected to the rotating outlet pipe in a one-to-one correspondence.

[0009] By adopting the above technical scheme, the crushed by-products (offal and scraps) are put into the enzymolysis chamber at the head end, and the corresponding biological enzymes are added to the enzymolysis chamber in proportion. The driving motor drives the constant temperature drum to rotate, and the by-products are slowly stirred by the stirring push piece to fully mix the by-products with the biological enzymes. With the continuous addition of by-products, the stirring push piece slowly pushes the by-products through the strip connecting groove into the next enzymolysis chamber, and during the rotation of the constant temperature drum, the heat source (hot water, hot air or steam) is connected from the horizontal heat pipe, and the heat source enters the inner drum and the biological enzyme along the rotating inlet pipe. The guide channel between the outer sleeves is introduced into the horizontal cold pipe through the rotating outlet pipe after heat exchange, and then discharged or circulated heated to increase the temperature of the outer sleeve. During the stirring process, the outer sleeve contacts the by-products, and the temperature of the by-products is gradually increased to meet the optimal temperature of enzymolysis. During the enzymolysis process, the by-products slowly pass through the enzymolysis chamber one by one to achieve the purpose of sufficient enzymolysis. After the enzymolysis is completed, the products are discharged from the strip discharge trough and fall onto the conveyor. The conveyor inputs the products into the tunnel drying bin, and the products are heated and dried in the tunnel drying bin by electric heating pipes.

[0018] In summary, the present invention has the following beneficial effects:

[0019] First, the present invention utilizes the rotation of the constant temperature drum to drive the byproducts to pass through the enzymatic hydrolysis chamber one by one, and perform multiple stages of enzymatic hydrolysis. In addition, the byproducts are fully stirred during the rotation process, so that the byproducts are fully mixed with the biological enzyme, making the enzymatic hydrolysis reaction more efficient and more thorough.

[0020] Secondly, the present invention uses the enzymolysis chamber to carry out a flow-type enzymolysis reaction, by-products can be continuously added during the process, and the product can be continuously and automatically output after the enzymolysis is completed. There is no need to manually transfer the by-products one by one to empty the enzymolysis tank, which helps to reduce work intensity and improve work efficiency;

[0021] Thirdly, during the enzymatic hydrolysis reaction, the present invention continuously passes hot water or hot air through the sandwich structure in the constant temperature drum to exchange heat with the byproducts, thereby maintaining a constant temperature environment in the enzymatic hydrolysis chamber and maintaining the optimal temperature for enzyme activity, thereby accelerating the enzymatic hydrolysis efficiency;

[0022] Fourthly, after the enzymatic hydrolysis reaction is completed, it enters the tunnel drying chamber for heating and drying.
