Description

Technical Field

[0001] This utility model relates to the field of fish paste production technology, and more specifically, to a multi-stage mixing and stirring device for the production of enzymatically hydrolyzed fish paste. Background Technology

[0002] Enzymatically hydrolyzed fish paste is a nutritious product made from low-value marine fish, small miscellaneous fish, or by-products of aquatic product processing (such as fish heads, skin, and viscera) using modern enzymatic hydrolysis technology. The production process mainly includes raw material pretreatment, pulverizing into fish paste, and then controlling hydrolysis using single or combined enzyme systems such as alkaline protease, neutral protease, trypsin, or papain. It is then refined through high-temperature sterilization and low-temperature vacuum concentration. This product is rich in small molecule peptides (especially oligopeptides composed of 2-10 amino acids), free amino acids, taurine, polyunsaturated fatty acids, and various minerals. It is characterized by comprehensive nutrition and high digestibility and absorption. During the raw material pretreatment process, a mixing device is required to stir and mix the materials.

[0003] For example, Chinese patent disclosure: A multi-stage mixing and stirring device for the production of seaweed and squid paste, application number: CN202120745852.9, includes a mixing box, a first grinding cylinder, and a second grinding cylinder. The mixing box has a grinding cylinder at its top. Motors are fixedly mounted at the tops of the first and second grinding cylinders. A first rotating rod is located inside the mixing box. A second rotating rod is located inside both the first and second grinding cylinders. A drive gear is fixedly mounted at one end of the first rotating rod, and a driven gear is fixedly mounted at one end of the second rotating rod. Multiple grinding blades are fixedly mounted at the outer end of the second rotating rod. Multiple first stirring rods and multiple second stirring rods are fixedly mounted at the outer end of the first rotating rod. This invention reduces the workload of workers and production time by simultaneously performing grinding and multi-stage mixing, thereby improving production efficiency. Furthermore, the multi-stage mixing results in more uniform mixing and a better mixing effect.

[0004] However, in the above-mentioned technical solutions, traditional mixing and stirring devices usually adopt the method of directly pouring liquid additives into tanks or injecting them through fixed pipelines. This method of concentrated addition of liquid additives is prone to causing excessively high local concentrations, which can lead to violent local reactions with the protein components in the material, resulting in protein denaturation and agglomeration, which seriously affects the delicate taste and quality stability of the product. At the same time, simple mechanical stirring is difficult to make high-viscosity materials and subsequently added liquids quickly and fully blend, resulting in low mixing efficiency, long homogenization time, and high energy consumption. Utility Model Content

[0005] The main objective of this invention is to provide a multi-stage mixing and stirring device for the production of enzymatically hydrolyzed fish paste. This device effectively solves the problems of traditional mixing and stirring devices that typically involve directly pouring liquid additives into tanks or injecting them through fixed pipes. This method of concentrated addition of liquid additives easily leads to excessively high local concentrations, causing violent local reactions with the protein components in the material, resulting in protein denaturation and agglomeration, which seriously affects the delicate taste and quality stability of the product. At the same time, simple mechanical stirring makes it difficult to quickly and fully integrate high-viscosity materials with the subsequently added liquid, resulting in low mixing efficiency, long homogenization time, and high energy consumption.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a multi-stage mixing and stirring device for the production of enzymatically hydrolyzed fish paste, comprising a tank body, a top cover provided on one side of the top of the tank body, an annular groove provided on one side of the bottom surface of the top cover, a rotating ring rotatably disposed within the annular groove, an annular infusion groove provided on the rotating ring, a plurality of atomizing nozzles provided on one side of the bottom surface of the rotating ring, the inlet of the atomizing nozzles communicating with the annular infusion groove, a plurality of sealing layers provided on the outer surface of the rotating ring, a driving component for driving its rotation provided on one side, a storage tank fixedly installed on one side of the top of the top cover, a water pump provided on the storage tank, and an infusion pipe communicating with the annular infusion groove provided on the water pump.

[0007] Preferably, the inner cavity of the tank is provided with a stirring paddle, which is rotatably mounted on the top cover. The stirring paddle is provided with several support columns, and scrapers are provided on the support columns. One end of the stirring paddle is provided with a first motor for driving its rotation.

[0008] Preferably, the scraper is in close contact with the inner wall surface of the tank, and the first motor is fixedly mounted on the top cover.

[0009] Preferably, the drive assembly includes a second motor fixedly mounted on the top cover, the output end of the second motor being connected to a rotating column, and a gear being provided on the rotating column.

[0010] Preferably, a gear ring is meshed on one side of the gear.

[0011] Preferably, the toothed ring is fixedly mounted on the outer wall surface of the rotating ring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When using this utility model, first open the top cover and put the main material into the inner cavity of the tank, then close the top cover. Then, inject the liquid auxiliary material into the storage tank, start the first motor to drive the stirring paddle to rotate. While the material is being stirred, the support column drives the scraper to rotate and scrape against the inner wall of the tank to prevent the material from adhering. During the stirring process, the water pump delivers the liquid auxiliary material in the storage tank to the annular delivery tank through the delivery pipe. At the same time, the drive component drives the rotating ring to drive the atomizing nozzle to revolve, atomizing the liquid auxiliary material and spraying it evenly onto the entire surface of the mixture, avoiding excessive local concentration that could cause protein denaturation or clumping, and achieving rapid and uniform distribution.
