Technical Field
The invention belongs to the technical field of cold chain transportation equipment and control strategies, and particularly relates to an ultralow-temperature fresh-keeping transportation box body based on multiple environment interaction.
Background
China has seen the consumption of tuna in the ten thousand ton age. The domestic market demand is rapidly increased, and the annual consumption of tunas is increased by more than 30 percent in nearly 10 years. However, tuna contains abundant myoglobin and has high oxidation speed, and transportation and storage at-60 ℃ must be ensured in order to keep the nutrition, color and taste of the tuna fresh. However, vehicles suitable for the ultra-low temperature transportation of tunas are not available in the prior art, and the existing refrigerated truck cannot realize the refrigeration condition of 60 ℃ below zero.
Based on this problem, we have conducted intensive studies and found that temperature is the most important factor affecting the quality of perishable products, and that severe fluctuations in temperature cause a dramatic decrease in the quality of perishable products. In the transportation process, due to the heat exchange effect, the temperature fluctuation inside the carriage is severe, and the perishable products are easy to decay. The refrigerated transport box body is used as an important transport facility for guaranteeing the quality of perishable products, and in the transport process, the accurate control of the temperature in the refrigerated carriage is a key technology for guaranteeing that food is in the most suitable environment during the transport, thereby guaranteeing the food safety.
In the prior art, the refrigeration carriage is not ideal in cooling effect in long-distance transportation, and mainly shows the following aspects:
the temperature control mode is single: the constant temperature module sensor for controlling the temperature is positioned near the air supply outlet, and the data acquisition range is limited, so that the air supply system circularly executes a single instruction.
② the temperature control accuracy is low: the system management is lack of refinement and intellectualization, temperature extreme points cannot be identified, and the direction of the air supply outlet is simplified.
Temperature control effect is inconsistent: the work of the system is delayed and reduced, the quality of perishable products is seriously influenced, and huge economic waste is caused.
Fourthly, the temperature control effect is not uniform: the cold air diffuser is arranged at the front part of the carriage, and the cooling performance is poor due to the long air supply distance.
The system operation consumes long time, consumes high energy, has poor low-temperature effect and is far less than the ultralow temperature of minus 60 ℃.

Experimental example 2
The tuna transported in example 1 was used as an experimental group, and the tuna transported in a refrigerator of the prior art was used as a control group, and sensory evaluation and measurement of TVB-N value and pH value were carried out, respectively.
1. Experimental methods
1.1 sensory evaluation
As the quality of tuna gradually decreases with the extension of the refrigerating time, various physical and chemical changes occur in the fish meat, resulting in significant changes in the external characteristics of the tuna, such as the meat texture, color and smell, and thus the quality of the tuna can be roughly judged through sensory organ evaluation.
The scoring standards are respectively made from three aspects of body surface color, muscle tissue and smell, the five ginsengs are scored, and the scores are averaged to obtain the experimental result. The scoring criteria are shown in table 1.
TABLE 1 tuna sensory evaluation criteria
1.2 volatile basic Nitrogen (TVB-N) determination
Tuna has a very high protein content and one of the main characteristics of its spoilage is protein breakdown, so the degree of spoilage can be measured by volatile basic nitrogen (TVB-N). Volatile basic nitrogen is a basic nitrogen-containing substance with specific odor generated after protein decomposition, and the higher the content of the substance, the stronger the odor is, which also indicates that the more serious the putrefaction degree is, the worse the quality is.
The experiment adopts a semi-micro Kjeldahl method for determination:
weighing 10.00g of minced and uniformly stirred tuna meat and placing the tuna meat in a conical flask; adding 100mL of water, shaking uniformly, soaking for 30min, filtering, and placing the filtrate in a refrigerator for later use; thirdly, placing a conical flask containing 10mL of absorption liquid and 5-6 drops of mixed indication liquid at the lower end of the condenser pipe, and inserting the lower end of the condenser pipe below the absorption liquid level; fourthly, accurately sucking 5.0mL of filtrate into a reaction chamber of the distiller, adding 5mL of magnesium oxide suspension (10g/L), quickly covering and plugging, and adding water to prevent air leakage; introducing steam, distilling for 5 min; sixthly, titrating the absorption liquid by using a hydrochloric acid standard titration solution (0.01mol/L), and finishing the end point to be bluish purple.
The calculation method comprises the following steps: volatile basic nitrogen content (mg/100g) =
；
Wherein: v1-titration of sample consumes standard acid solution volume (mL); v2Titration of the blank consumes a standard acid solution volume (mL); m-mass (g) of sample contained in the sample liquid for titration; c-specified concentration (mol/L) of standard acid solution; 14-molar mass of nitrogen (g/mol).
1.3 determination of pH
The tuna is acidic, the pH value of the oxidized myoglobin composition in the tuna is 6.0-6.5, and the quality of the tuna can be judged by measuring the pH value of the tuna at different temperatures in each refrigeration stage.
Weighing 10.00g of tuna meat as a sample for each measurement, shaking with 100mL of newly boiled and cooled water, soaking for 30min, filtering, putting 50mL of filtrate into a beaker, and measuring the pH value by using a precision acidimeter.
2 results of the experiment

2.2 variation of volatile basic Nitrogen TVB-N
Results see figure 7. refrigeration temperatures of-30 ℃ and-18 ℃ have some effect on freshness, -refrigeration conditions of-18 ℃ have the most significant effect on freshness, whereas the freshness of tuna (example 1) fish refrigerated at a refrigeration temperature of-60 ℃ does not change significantly.
2.3 change of pH
As a result, referring to FIG. 8, the pH curve of tuna (example 1) refrigerated at a refrigerating temperature of-60 ℃ was almost constant with little fluctuation, whereas the pH curve showed a tendency to decrease at refrigerating temperatures of-18 ℃ and-30 ℃ with the rate of decrease of pH at-18 ℃ being most significant.
