The use of refrigerated trucks to transport different items should be consistent with the temperature adjustments in the insulated cars, or else it will cause deterioration and damage to the items. When refrigerating trucks transport fruit and vegetable products, how do they adjust to the right temperature?
1. Most of the transport temperature in the frigid and temperate leaves and rhizomes is preferably between zero and two degrees Celsius, and it is better not to be lower than zero. And we usually eat fruits and vegetables such as. spinach. Fresh fruits and vegetables such as grapes, celery, Chinese cabbage and so on, do not rush to store in the cold storage just after picking it back, because in the low temperature environment, the enzyme activities in the fruits and vegetables are prefabricated, so there is no way Decompose the residue that remains on the fruits and vegetables. So, after putting the fruits and vegetables in the greenhouse for 24 hours, it is the best choice to put into the cold room.
2, some fruits and vegetables in the moisture content is more, if it is a long time after the refrigerated there will be taste, deterioration of the situation, so it is best to store at about ten degrees Celsius temperature. For example: fruits and vegetables such as pumpkins, cucumbers, wax gourds, tomatoes, etc.
3, tropical fruit because it is the reason for the growth of the environment, so it is best to be placed in some relatively cool or can avoid the sun's direct place to save. If it is necessary to use a refrigerated truck for transport, then the best transportation temperature is in the range of 7-10 degrees Celsius, and when transporting, the time must be the best is not to exceed 48 hours.
4. When using a refrigerated truck to transport fresh milk, the temperature is preferably around 2-4 degrees Celsius. When transporting frozen fish, it is best to adjust the temperature of the insulated compartment to a temperature below minus 3 degrees Celsius. In such a temperature environment, the frozen fish will not be degraded and the umami taste can be maintained.
The real development of investment casting in China is only a few decades. In the past few decades, China's development has been very rapid, and its proportion in the world is very high. For some workpieces with complex structures and not very high precision requirements, if it is difficult to process with CNC or the processing cost is high, such workpieces are especially suitable for investment casting. Even if some parts require precision assembly, we can meet the requirements through local precision CNC machining, thereby reducing costs. Especially for stainless steel castings, it is used in many places. Because of its strong corrosion resistance, high strength and toughness, stainless steel can be used in some harsh environments. For the processing of stainless steel parts, it is nothing more than precision CNC machining, forging processing, stamping processing, casting processing or powder metallurgy processing, etc., and investment casting is a relatively low-cost, high-precision processing method.
SCZY is a professional manufacturer of metal products. Many stainless steel castings we produce are used in marine projects, navigation, medical equipment and other industries. We not only provide metal investment casting processing, but also provide supporting follow-up secondary CNC machining and Surface treatment machining. We can ensure product accuracy requirements and appearance quality requirements.
