Description

Technical Field

[0001] The present invention relates to the technical field of food storage, and particularly refers to a constant temperature box device for food analysis. Background Art

[0002] Food analysis refers to the sampling inspection of finished food products to determine whether the food meets the hygiene standards and can be sold normally. When sampling and testing food, it is usually necessary to store the extracted food samples. To prevent the food samples from deteriorating, a constant temperature box is required for food storage.

[0003] A patent for invention with the application number 202311099052.4 discloses a refrigerated packaging box for transporting meat products, and specifically discloses the technical solution of "the drainage part is arranged at the bottom of the box body, and the drainage part is funnel-shaped; a water outlet is arranged at the bottom of the drainage part".

[0004] Although the technical solution of this application has the function of discharging the accumulated water from the melting ice layer through the water outlet at the bottom, it is not suitable for freshly divided meat products with grease and blood. In an environment of cold air preservation, the viscous grease and blood flowing from the fresh meat products are likely to freeze and block the water outlet, making it difficult to control the storage humidity of the meat products and prone to bacterial growth. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a constant temperature box device for food analysis. To solve the problems that it is difficult to control the storage humidity of fresh meat products in the constant temperature box and it is prone to bacterial growth, the present invention proposes a constant temperature box device for food analysis that can reduce the storage humidity of fresh meat products in the constant temperature box.

[0041] As Figures 1 to 12 shown, a plurality of storage cells 102, a dehumidification storage component 5 and a dehumidification detection component 9 are arranged in the outer box body 1 in a rectangular array. Heat exchange holes 103 are formed in each of the plurality of storage cells 102. A refrigeration space 101 communicated with the heat exchange holes 103 is formed at the top of the outer box body 1.

[0043] As Figures 1 to 12 shown, the refrigerator 2 is a semiconductor refrigerator.

[0044] During specific use, after the user pulls open the push-pull side shell 3, fresh meat products are placed into the first-stage storage cylinder 601, and then the push-pull side shell 3 is closed. The refrigerator 2 cools down and reduces the temperature inside the outer box body 1 through the heat exchange holes 103.

[0045] After the fresh meat products are placed into the first-stage storage cylinder 601, the grease and blood water flow out by converging in the moisture discharge groove 6012. To avoid the problem that the grease and blood water solidify in the moisture discharge groove 6012 at low temperature and cause the storage humidity of the meat products to be too high, the composite belt dehumidification unit 7 starts to work after the fresh meat products are placed into the first-stage storage cylinder 601. The specific principle is as follows: the winding motor 704 overcomes the resistance of the torsion shaft 702 and pulls the double-layer dehumidification belt 706 from the release box 701 into the winding box 703. During the process of the double-layer dehumidification belt 706 being dragged by the winding motor 704, it passes through the moisture discharge groove 6012 and continuously takes away the moisture such as grease and blood water in the moisture discharge groove 6012.

[0046] Under the combined action of the refrigerator 2 and the composite belt dehumidification unit 7, part of the grease and blood water attached to the fresh meat products flows out from the moisture discharge tank 6012, and part freezes on the surface of the meat products to form an ice layer, so that the moist fresh meat products can be gradually dried in the primary storage cylinder 601. After the meat products are dried, the closing door 6011 is temporarily opened, and the multi-stage electric push rod 604 extends. Through the extrusion action of the pushing plate 605, the meat products are pushed into the secondary storage cylinder 603 through the connecting plate 602, which avoids the problem that the dried meat products come into contact with the grease and blood water on the inner wall of the primary storage cylinder 601 and are prone to bacterial growth. During subsequent food analysis, the user only needs to open the access door 6031 and take out the meat product sample from the secondary storage cylinder 603.

[0047] When the meat products are pushed from the primary storage cylinder 601 to the secondary storage cylinder 603, it is necessary to ensure that the meat products are dry and no longer overflow with grease and blood water. Correspondingly, the working principle of the dehumidification detection component 9 is as follows: When the winding motor 704 drags the double-layer dehumidification belt 706, the vibrator 1102 in the matting powder application unit 11 drives the matting powder puff 1103 to vibrate, and sprinkles the matting powder on the aluminum foil 7062. Subsequently, the aluminum foil 7062 with matting powder enters the powder blowing unit 12, and the side air blower 1202 blows out a gentle breeze to blow the matting powder on the aluminum foil 7062 with a small wind force.

[0048] If grease and blood water overflow downward from the meat products when this part of the aluminum foil 7062 passes through the moisture discharge tank 6012, the grease and blood water will be adsorbed by the oil absorbent paper 7061, and sticky oil stains and blood stains will be left on the surface layer of the aluminum foil 7062 that is closely attached to the oil absorbent paper 7061. The sticky stains on this part of the aluminum foil 7062 have a fixing effect on the matting powder and can prevent the matting powder from being blown away by the side air blower 1202.

[0049] If the meat products are already dry when this part of the aluminum foil 7062 passes through the moisture discharge tank 6012, the double-layer dehumidification belt 706 composed of the oil absorbent paper 7061 and the aluminum foil 7062 will not carry grease and blood water after entering the winding box 703. The matting powder on this part of the aluminum foil 7062 only stays on the aluminum foil 7062 by gravity, and will leave the surface of the aluminum foil 7062 under the action of the wind force of the side air blower 1202 and stay in the collection box 1201.

[0050] When the aluminum foil 7062 passes under the reflection detection unit 10, the light emitted by the light source irradiates the aluminum foil 7062, and specular reflection occurs with the aluminum foil 7062 as the reflection surface and is reflected to the illuminance sensor 1003 (the hollow reflection frame 1001 with a light-transmitting groove 10011 at the bottom serves to restrict the light path, preventing the light emitted by the light source from being diffusely reflected to the illuminance sensor 1003 by other objects, thus affecting the detection accuracy). If the meat product overflows with grease and blood, a certain amount of extinction powder adheres to the surface of the inspected part of the aluminum foil 7062. The gloss of the inspected part of the aluminum foil 7062 decreases and the reflection ability is low, and the illuminance received by the illuminance sensor 1003 is relatively low. If the meat product is dry, the surface of the inspected part of the aluminum foil 7062 remains smooth and good specular reflection occurs, and the illuminance sensor 1003 receives a sufficiently high illuminance.

[0051] After the illuminance sensor 1003 receives a sufficiently high illuminance and maintains it for a certain period of time, the industrial control computer 4 can determine that the meat product in the primary storage cylinder 601 is completely dry, and transfer the meat product to the cleaner secondary storage cylinder 603 through the coordinated use of the multi-stage electric push rod 604, the push plate 605 and the closing door 6011.

[0052] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
