Description

Technical Field

[0001] This utility model belongs to the field of microbial production technology, specifically relating to an apparatus for preparing yeast lysate. Background Technology

[0002] Yeast lysate is a commonly used ingredient in cosmetics and personal care products. It is extracted from yeast cells (such as Bifida ferment lysate and baker's yeast) through a specific process. Specifically, yeast lysate is obtained by breaking down the yeast cell walls to release the nutrients inside the cells. These nutrients mainly include peptides, amino acids, vitamins, minerals, and antioxidants.

[0003] In preparing yeast lysate, firstly, the staff cultivates yeast strains in a culture medium to obtain a sufficient density of yeast cells; then, the yeast cells are separated from the culture medium using separation technology and washed with water; finally, the yeast cells are broken down and concentrated to obtain a high-concentration yeast lysate product.

[0004] However, the yeast cell wall has a tough, multi-layered structure (including components such as glucan, mannan, and proteins), which makes it difficult to break down. Moreover, if mechanical crushing is used alone, the cell wall may not be completely broken down due to insufficient mechanical force of the equipment. If the yeast cell wall is not effectively broken down, the nutrients inside the yeast cell cannot be fully released into the solution, thereby reducing the extraction efficiency and affecting the stability of the product. Therefore, a yeast lysate preparation device is needed to solve the above problems. Utility Model Content

[0007] Cultivation equipment;

[0008] A collection device, which is connected to the culture device via a pipe;

[0009] A heating device includes a heating cylinder, a material tube, and a heating resistance wire. The material tube and the heating resistance wire are installed inside the heating cylinder, and the material tube is in contact with the heating resistance wire. The material tube and the heating resistance wire are made of heat-conducting materials. Both the material tube and the heating resistance wire are spiral-shaped. The upper end of the material tube is connected to the collecting device through a pipe.

[0010] A crushing device, wherein the crushing device is connected to the lower end pipe of the material pipe;

[0011] A filtration device is connected to the crushing device via a pipeline.

[0012] As a preferred embodiment, the heating device further includes a separator cylinder, which is vertically installed inside the heating cylinder and coaxial with the heating cylinder. The material tube is installed between the outer wall of the separator cylinder and the inner wall of the heating cylinder, and the heating resistance wire is installed inside the separator cylinder.

[0013] As a preferred embodiment, the heating device further includes multiple partitions, which are horizontally installed at intervals inside the partition cylinder and fit against the inner wall of the partition cylinder. Multiple heating resistance wires are also provided, which are installed between two adjacent partitions, and the length of the heating resistance wires gradually increases from top to bottom.

[0014] As a preferred embodiment, the heating device further includes connecting rods, which are provided in two sets, with multiple connecting rods in each set. The multiple connecting rods are spaced apart at the ends of the heating cylinder, and the connecting rods connect the heating cylinder and the partition cylinder.

[0015] As a preferred embodiment, the crushing equipment includes a crushing cylinder, crushing steel balls, a rotating gear ring, a rotating gear meshing with the rotating gear ring, a rotating motor, and a mounting frame. Multiple crushing steel balls are provided and placed inside the crushing cylinder. The rotating gear ring is installed at one end of the crushing cylinder.

[0016] As a preferred embodiment, the heating device further includes a mounting frame, on which the heating cylinder is vertically mounted.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention comprises a heating cylinder, a feed tube, and a heating resistance wire. The feed tube and heating resistance wire are installed inside the heating cylinder, with the feed tube and heating resistance wire in close contact. Both the feed tube and heating resistance wire are made of heat-conducting materials and are spiral-shaped. The upper end of the feed tube is connected to a collection device via a pipe. The fermentation broth in the collection device, after being centrifuged, enters the upper end of the feed tube through the pipe. Under the action of gravity, the fermentation broth in the feed tube gradually falls. At the same time, the energized heating resistance wire converts electrical energy into heat energy, thereby dissipating heat. The dissipated heat is transferred to the fermentation broth in the feed tube by the heat-conducting separator and the feed tube. Through heating, the structure of the yeast cell wall in the fermentation broth is changed, reducing the mechanical strength of the cell wall and resulting in better subsequent crushing effect.

[0019] This invention features multiple partitions horizontally installed at intervals inside a separating cylinder, adhering to the inner wall of the cylinder. Multiple heating resistance wires are installed between adjacent partitions, with their length gradually increasing from top to bottom. This design ensures that the fermentation liquid in the feed tube is heated to an increasingly higher temperature as it falls, preventing sudden high temperatures that could rupture yeast cells and also preventing the active substances in the fermentation liquid from becoming inactive or degraded at high temperatures.

Multiple heating resistance wires 33 are provided, and multiple heating resistance wires 33 are respectively installed between two adjacent partitions 35, and the length of the heating resistance wires 33 gradually increases from top to bottom.

[0034] The heating device 3 also includes connecting rods 36. There are two sets of connecting rods 36, and each set of connecting rods 36 has multiple connecting rods 36.

[0035] The crushing equipment 4 includes a crushing cylinder 41, crushing steel balls 42, a rotating gear ring 43, a rotating gear 44 meshing with the rotating gear ring 43, a rotating motor 45, and a mounting frame 46.

[0036] The heating device 3 also includes a fixing frame 37, and the heating cylinder 31 is vertically installed on the fixing frame 37.

[0037] Working principle and usage process of this utility model:

[0038] First, workers select a suitable yeast strain and ferment it in culture device 1 to obtain sufficient yeast cells. Then, the fermented liquid in culture device 1 enters collection device 2 via a pipe. The fermentation liquid in collection device 2 is centrifuged and then enters the upper end of feed pipe 32 via a pipe. Under gravity, the fermentation liquid in feed pipe 32 gradually falls. Simultaneously, the energized heating resistance wire 33 converts electrical energy into heat energy, dissipating heat. This heat is transferred to the fermentation liquid in feed pipe 32 by the thermally conductive separator 34 and feed pipe 32. Heating alters the structure of the yeast cell walls in the fermentation liquid, reducing the mechanical strength of the cell walls and resulting in better subsequent crushing.

[0039] In addition, since there are multiple heating resistance wires 33, and the length of the multiple heating resistance wires 33 gradually increases from top to bottom, the fermentation liquid in the feed tube 32 is heated to a higher and higher temperature during the falling process, which avoids sudden high temperature causing the yeast cells to rupture, and at the same time prevents the active substances in the fermentation liquid from being inactivated or degraded at high temperature.

[0040] The fermentation broth heated by the heating device 3 enters the crushing cylinder 41 through a pipeline. The rotating motor 45, after starting, drives the rotating gear 44 to rotate, which in turn drives the rotating gear ring 43 and the crushing cylinder 41 fixedly connected to the rotating gear ring 43 to rotate as well. At this time, the crushing steel ball 42 rises along the inner wall of the crushing cylinder 41 under the action of inertia, and then falls freely, thereby generating impact and friction on the fermentation broth, thus achieving crushing treatment. Finally, the fermentation broth crushed by the crushing device 4 enters the filtration device 5 for filtration treatment.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
