Description

Technical Field

[0001] This utility model relates to the field of whey protein peptide production technology, and in particular to a low-temperature concentration device for whey protein peptide production. Background Technology

[0002] Whey protein peptides are short-chain amino acids extracted from whey protein, typically obtained by enzymatic hydrolysis of whey protein. Whey protein peptides have a relatively small molecular weight, usually between 500 Da and 2000 Da, which allows them to quickly pass through the intestinal wall into the bloodstream, enabling the body to utilize the nutrients they provide more efficiently.

[0003] In the production of whey protein peptides, after whey protein is enzymatically hydrolyzed, a whey protein peptide hydrolysate is obtained. The concentration of whey protein peptides in the hydrolysate is low, so the hydrolysate needs to be concentrated. This facilitates the enrichment of whey protein peptides, makes the storage and transportation of the hydrolysate easier, and also makes it easier to convert the hydrolysate into powder form.

[0004] However, in existing concentration processes, as the enzymatic hydrolysate loses some water and becomes increasingly viscous in the low-temperature concentration tank, it easily adheres to the inner wall of the tank. This not only affects heat transfer efficiency but may also lead to a decline in product quality. Furthermore, the current process lacks effective cleaning of the inner wall of the concentration tank, which can cause residue accumulation and increase cleaning difficulty. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a low-temperature concentration device for the production of whey protein peptides.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A low-temperature concentration device for whey protein peptide production includes a low-temperature concentration tank for enzymatic hydrolysate. A modular end cap is bolted to the upper end of the tank. A shaft-end power coupler is located above the modular end cap. A stirring mechanism connected to the shaft-end power coupler is located inside the tank. An annular water storage sleeve is fixedly connected to the upper end of the modular end cap. Multiple Venturi self-priming spray units are fixedly connected to the lower end of the modular end cap. The upper ends of the multiple Venturi self-priming spray units penetrate the modular end cap and communicate with the annular water storage sleeve. A water supply mechanism connected to the annular water storage sleeve is located on one side of the tank. A heating mechanism is located on the outer wall of the tank.

[0008] As a further improvement of this utility model, the stirring mechanism includes a servo motor direct drive shaft rotatably connected to the lower end of the modular end cap. The output shaft of the shaft-end power coupler passes through the modular end cap and is fixedly connected to the servo motor direct drive shaft. Multiple composite transmission horizontal shafts are sequentially fixedly inserted on the servo motor direct drive shaft. The interior of the low-temperature concentration tank for enzymatic hydrolysate is provided with two dynamic recovery cutting edges that fit against the inner wall of the low-temperature concentration tank for enzymatic hydrolysate. The same end of the multiple composite transmission horizontal shafts is fixedly connected to one dynamic recovery cutting edge, and the other end of the multiple composite transmission horizontal shafts is fixedly connected to another dynamic recovery cutting edge.

[0009] As a further improvement of this utility model, the water supply mechanism includes a dynamic liquid control system disposed on one side of the low-temperature concentration tank of the enzymatic hydrolysate. The upper end of the dynamic liquid control system is fixedly connected to a hydraulic power conversion system that communicates with its interior. The other end of the hydraulic power conversion system is fixedly connected to a water distribution pipe column, and the other end of the water distribution pipe column communicates with the interior of the annular water storage jacket.

[0010] As a further improvement of this utility model, the heating mechanism includes an external circulation temperature control sleeve fixedly sleeved on the outer wall of the low-temperature concentration tank of the enzymatic hydrolysate, and a resistance heat source module is wound inside the external circulation temperature control sleeve.

[0011] As a further improvement of this utility model, the upper end of the low-temperature concentration tank for enzymatic hydrolysate is provided with an enzymatic peptide raw material introduction section, the lower end of the enzymatic peptide raw material introduction section passes through the modular end cap and communicates with the interior of the low-temperature concentration tank for enzymatic hydrolysate, and the other side of the modular end cap away from the enzymatic peptide raw material introduction section is provided with a steam drum connection end, the steam drum connection end passes through the modular end cap and communicates with the interior of the low-temperature concentration tank for enzymatic hydrolysate.

[0012] As a further improvement of this utility model, the lower end of the low-temperature concentration tank for the enzymatic hydrolysate is supported by multiple flange connection bases, and the same enzymatic hydrolysate guide section is provided between the multiple flange connection bases. The upper end of the enzymatic hydrolysate guide section penetrates through the low-temperature concentration tank for the enzymatic hydrolysate and communicates with its interior.

[0013] The beneficial effects of this utility model are:

[0014] By incorporating two dynamically recoverable cutting edges that adhere to the inner wall of the low-temperature concentration tank for enzymatic hydrolysate, and fixing one end of multiple composite transmission shafts to one of these cutting edges and the other end to another, these cutting edges effectively scrape off liquid milk adhering to the inner wall of the tank during stirring and reintroduce it into the stirring process. This effectively prevents liquid milk from adhering to the inner wall of the tank during evaporation, thus avoiding reduced heat transfer efficiency and product quality due to material adhesion.

[0015] By incorporating a water supply mechanism, a Venturi self-priming spray unit, and an annular water storage jacket, when cleaning is required, the hydraulic power conversion system is activated to draw water from the dynamic liquid control system into the annular water storage jacket through the water distribution pipe column. The water is then sprayed out through multiple Venturi self-priming spray units to thoroughly clean the inner wall and internal components of the low-temperature concentration tank for the enzymatic hydrolysate. This ensures that the low-temperature concentration tank and its internal components are thoroughly cleaned after each use, solving the problem of insufficient cleaning in traditional processes, preventing residue accumulation, reducing cleaning difficulty, and ensuring the hygienic condition of the equipment.

[0016] This invention effectively prevents liquid milk from adhering to the inner wall of the low-temperature concentration tank of the enzymatic hydrolysate, thus avoiding affecting heat transfer efficiency and product quality. It also ensures equipment hygiene and reduces cleaning difficulty through an automatic cleaning system. Attached Figure Description

The output shaft of the end power coupler 5 passes through the modular end cover 3 and is fixedly connected to the servo motor direct drive shaft 14. The end power coupler 5 will start the servo motor direct drive shaft 14 to rotate. Multiple composite transmission horizontal shafts 15 are sequentially fixedly inserted on the servo motor direct drive shaft 14. The rotation of the servo motor direct drive shaft 14 will drive the multiple composite transmission horizontal shafts 15 to rotate. The liquid milk is thoroughly stirred by the dynamic movement of the hydrolysate low-temperature concentration tank 1. The interior of the hydrolysate low-temperature concentration tank 1 is equipped with two dynamic recovery cutting blades 16 that are attached to the inner wall of the hydrolysate low-temperature concentration tank 1. The same end of multiple composite transmission horizontal shafts 15 is fixedly connected to one dynamic recovery cutting blade 16, and the other end of multiple composite transmission horizontal shafts 15 is fixedly connected to another dynamic recovery cutting blade 16. The design of the two dynamic recovery cutting blades 16 can effectively scrape off the liquid milk that is stuck to the inner wall of the hydrolysate low-temperature concentration tank 1 and add it back into the stirring process, avoiding material waste and affecting heat transfer efficiency.

[0023] An annular water storage sleeve 4 is fixedly connected to the upper end of the modular end cap 3. The annular water storage sleeve 4 is used to temporarily store water. Multiple Venturi self-priming spray units 13 are fixedly connected to the lower end of the modular end cap 3. The multiple Venturi self-priming spray units 13 are used to diffuse and spray water in a mist, thereby cleaning the inside of the low-temperature concentration tank 1 of the enzymatic hydrolysate. The upper ends of the multiple Venturi self-priming spray units 13 all penetrate the modular end cap 3 and communicate with the annular water storage sleeve 4. A water supply mechanism connected to the annular water storage sleeve 4 is provided on one side of the low-temperature concentration tank 1 of the enzymatic hydrolysate. The water supply mechanism includes a dynamic liquid control system 8 set on one side of the low-temperature concentration tank 1 of the enzymatic hydrolysate.

The heat generated by the resistance heat source module 12 will heat the low-temperature concentration tank 1 of the enzymatic hydrolysate, promote water evaporation, and improve the concentration efficiency.

[0024] In use, the worker first pours liquid milk from the enzymatic hydrolysate raw material inlet section 9 into the low-temperature concentration tank 1 of the enzymatic hydrolysate. Then, the power supply to the external circulation temperature control sleeve 2 is turned on. The resistance heat source module 12 inside the external circulation temperature control sleeve 2 will generate heat, thereby heating the low-temperature concentration tank 1 of the enzymatic hydrolysate. Subsequently, the shaft-end power coupler 5 is started to drive the servo motor direct drive shaft 14 to rotate. The rotation of the servo motor direct drive shaft 14 will drive multiple composite transmission horizontal shafts 15 to rotate, thereby stirring the liquid milk to ensure uniform heating. The water vapor generated during heating will be discharged from the steam drum connection end 17. Meanwhile, the two dynamic recovery cutting edges 16 scrape off the liquid milk adhering to the inner wall of the low-temperature concentration tank 1 and add it back into the stirring. After the liquid milk is concentrated, it can be discharged by opening the valve of the enzymatic peptide liquid guide section 11. When it is necessary to clean the inside of the low-temperature concentration tank 1, the hydraulic power conversion system 7 is activated to draw water from the dynamic liquid control system 8 through the water distribution column 6 into the annular water storage sleeve 4, and spray it out through multiple Venturi self-priming spray units 13 to clean the inner wall and internal components of the low-temperature concentration tank 1.
