Problems solved by technology

[0005] ①Single temperature control mode: the thermostat module sensor for temperature control is located near the air supply outlet, and the data collection range is limited, resulting in the air supply system cyclically executing a single command
[0006] ②Low temperature control accuracy: the system management lacks refinement and intelligence, cannot identify temperature extreme points, and the direction of the air supply port is single
[0007] ③ Inconsistent temperature control effect: there are delays and reductions in system work, which seriously affects the quality of perishable products and causes huge economic waste
[0008] ④ Uneven temperature control effect: The cold air diffuser is set at the front of the compartment, and the cooling performance is poor due to the long air supply distance
[0009] ⑤ The system takes a long time to work, consumes a lot of energy, and the effect of low temperature is poor, far below -60°C ultra-low temperature

Embodiment 1

[0044] Such as figure 1As shown, an ultra-low temperature preservation transport box based on multiple environment interactions, including: a refrigerated container, a movable ultra-low temperature preservation transport refrigerator, and an ultra-low temperature refrigerator control system;

[0045] The refrigerated container includes a container body, an air supply duct 1, a moving tuyere 2, and a butterfly valve 3 arranged above the container body, a refrigeration area 4 and a power supply area 5 arranged in front of the container body; the container body is composed of a first module 6 and a second module 7 1. The third module 8 is composed, and between the first module 6 and the second module 7, between the second module 7 and the third module 8, there are flipping partitions 9;

[0046] The power supply area 5 is connected to the refrigeration area 4 through a circuit, and the power supply area 5 supplies power to the refrigeration area 4; the mobile tuyere 2 is connecte...

experiment example 1

[0057] A kind of ultra-low temperature fresh-keeping transport box based on multiple environmental interactions in Example 1 was used as the experimental group, and the refrigerated carriage of the prior art was used as the control group, and the temperature was controlled according to their respective control systems. After 5 hours, the CFD software was used to pair the experiment. The temperature distribution inside the transport box of the group and the control group was analyzed, and the results can be found in Figure 4 and Figure 5 . It can be clearly seen from the pictures that the multi-environment interaction-based ultra-low temperature fresh-keeping transport box of the present invention has good temperature control effect, uniform and consistent temperature distribution, and has significant advantages.

experiment example 2

[0059] The tuna transported in Example 1 was used as the experimental group, and the tuna transported in the refrigerator of the prior art was used as the control group, and the sensory evaluation, TVB-N value and pH value were measured respectively.

[0060] 1. Experimental method

[0061] 1.1 Sensory evaluation

[0062] As the storage time prolongs, the quality of tuna will gradually decline, and various physical and chemical changes will occur in the fish meat, resulting in obvious changes in the external characteristics of tuna, such as meat texture, color and smell, so it can be roughly judged by sensory organ evaluation Tuna quality.

[0063] Scoring standards were established from the three aspects of body surface color, muscle tissue and smell, and five people participated in the scoring, and the scores were averaged to obtain the results of this experiment. See Table 1 for scoring criteria.

Description

technical field [0001] The invention belongs to the technical field of cold chain transportation equipment and control strategies, and in particular relates to an ultra-low temperature preservation transportation box based on multiple environment interactions. Background technique [0002] my country's tuna consumption has entered the era of "10,000 tons". The domestic market demand is growing rapidly. In the past 10 years, the annual growth rate of tuna consumption has reached more than 30%. However, tuna is rich in myoglobin, and the oxidation rate is very fast. In order to keep the nutrition, color and taste of tuna fresh, it must be transported and stored at -60°C. However, there is no vehicle suitable for ultra-low temperature transportation of tuna in the prior art, and the existing refrigerated vehicle cannot realize the cold storage condition of -60°C. [0003] Based on this problem, we conducted in-depth research and found that temperature is the most important fa...
