Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary supporting equipment for probiotic production, in particular to a probiotic freeze-drying device. Background Art

[0002] Probiotics are beneficial intestinal bacteria that regulate the balance of intestinal flora and enhance intestinal digestive function. During the production process of probiotics, the probiotics need to be freeze-dried and sealed. The existing freeze-drying machines have good freeze-drying effects, less damage to the bacteria, and good freeze-drying storage resistance when freeze-drying probiotics. However, in the actual production process, we usually also need to sample the freeze-dried probiotics and send them to the laboratory for testing. Probiotics need to be kept in a freeze-dried state as much as possible during the inspection process. Conventional insulation boxes (also called cold-keeping boxes) have a certain cold-keeping effect, but this cold-keeping effect can only keep the freeze-dried probiotics in a state for a period of time. In actual applications, the probiotics may not be detected or delivered in time due to various factors, resulting in a certain degree of micro-melting of the probiotics and affecting the accuracy of the detection. To this end, a probiotic freeze-drying device is needed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0018] Next, the present invention is described in detail with reference to schematic diagrams.

[0020] Figure 1-Figure 3 The diagram shows the entire structure of a probiotic freeze-drying device of the present invention. Figure 1-Figure 3 A probiotic freeze-drying device according to the present embodiment includes an insulating outer shell 100, an inner storage shell 110 is provided on the inner side of the insulating outer shell 100, and a storage compartment is provided on the inner side of the storage inner shell 110. A cold air cavity 120 is provided between the inner side of the insulating outer shell 100 and the storage inner shell 110. Several vents 1101 connected to the cold air cavity 120 are distributed around and on the bottom of the storage inner shell 110. A sealing cover plate 200 adapted to the same is provided on the top of the insulating outer shell 100, and a refrigeration element 300 is provided at the bottom of the cold air cavity 120. By starting the refrigeration element 300, cold energy is input into the cold air cavity 120.

[0021] The heat-insulating shell 100 includes an outermost protective shell 101 and a heat-insulating layer 102 that fits the inner side of the outer protective shell 101. It is understood that the outer protective shell 101 forms external protection, and the heat-insulating layer 102 can prevent the cold air cavity 120 and the cold air inside the device from escaping. The heat-insulating layer 102 here can be made of heat-insulating materials such as insulation boards. The refrigeration element 300 is a semiconductor refrigeration plate, and the heat-absorbing surface of the refrigeration element 300 is located on the inner side of the cold air cavity 120, while the heat-dissipating surface is located on the outer bottom of the heat-insulating shell 100. The heat-dissipating surface at the bottom of the refrigeration element 300 is also distributed with a number of heat-dissipating fins 310. The bottom of the heat-insulating shell 100 also has a mounting hole 130 corresponding to the refrigeration element 300. In order to improve the cooling effect of the semiconductor refrigeration plate, the heat dissipation efficiency of the refrigeration plate can be improved by the heat dissipation fins 310, thereby improving its heat exchange efficiency and cooling effect; specifically, in this embodiment, when in use, first turn on the refrigeration component 300 to cool the inside of the box, and after the temperature drops to a suitable temperature, put the freeze-dried probiotics into the storage compartment, and then close the sealing cover 200, and then it can be taken for inspection. During this process, the refrigeration component 300 injects cold energy into the cold air cavity 120 through continuous cooling, and then the cold air flows into the storage compartment through the vent 1101 and contacts with the probiotics, so that the probiotics are in a continuous low-temperature environment and will not melt slightly, thereby ensuring the accuracy of the detection and bringing convenience to the production and inspection of probiotics.

[0022] Furthermore, a control panel 400 is provided on the front of the heat-insulating housing 100, and a battery is housed within the control panel 400. It is understood that the battery provides power to the refrigeration element 300 and can be replaceable or rechargeable, without limitation. Furthermore, a temperature sensor can be provided within the housing. The control panel 400 and the temperature sensor allow the operator to set the cooling power and time of the refrigeration element 300, thereby maintaining the storage compartment at a suitable low temperature.

[0023] Furthermore, a carrying handle 210 is provided at the center of the top of the sealing cover plate 200. The carrying handle 210 makes it convenient for staff to carry the device box. The contact surface between the sealing cover plate 200 and the thermal insulation shell 100 can be threaded, snap-fit, etc. The inner side of the sealing cover plate 200 also has a thermal insulation layer.

[0024] Furthermore, support legs 500 are provided at the four corners of the bottom of the heat-insulating shell 100. The support legs 500 can elevate the bottom of the heat-insulating shell 100, so that the refrigeration element 300 has enough space to dissipate heat.

[0025] In summary, when a probiotic freeze-drying device according to this embodiment is used, the refrigeration component 300 is first turned on to cool the inside of the box, and after the temperature drops to a suitable temperature, the freeze-dried probiotics are placed in the storage compartment, and then the sealing cover 200 is closed. The probiotics can then be picked up for inspection. During this process, the refrigeration component 300 injects cold energy into the cold air cavity 120 through continuous cooling, and then the cold air flows into the storage compartment through the vent 1101 and comes into contact with the probiotics, so that the probiotics are in a continuous low-temperature environment and will not melt slightly, thereby ensuring the accuracy of the detection.

[0026] While the present invention has been described above with reference to specific embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the embodiments disclosed herein may be combined with one another in any manner, and the omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
