Temat postu: air jordan shoes cheap How cold storage cooling Ch
How cool chestnut Cold Storage
While the participation of oxygen consumption of nutrients in their {the release of heat, lack of distribution of heat released, making the chestnut temperature, further exacerbating the physiological breathing. According to our observation platform in the cold, cold when arriving by car chestnut, chestnut bag's temperature between 22 ℃ to 32 ℃ higher than the ambient temperature of 4 ℃ ~ 7 ℃. Followed by the chestnut into the storage after cold storage cooling material, since the higher the density of bags, if not improve the air supply, cooling method, chestnut in one or two days to complete the cooling process can not be so prone to mildew rot. For this reason, attention should be stored before the chestnut storage cooling problems. Fruit soon cooled to the temperature specified temperature. This would inhibit the chestnut breathing quickly, evaporation and other physical activities to prevent the freshness and quality of its decline. The temperature of chestnut fruit internal control standards that we set up a chestnut storage 24 'resistance, the bag temperatures should be lower than 10C, 48 hours later than 4C, 96 hours should be between 0C to 2C Chestnut in the cold library, and cooling requirements of the cooling required to reach the top speed, we not only strengthen the temperature control, with the compressor run-time, library circulation air flow, evaporator using the stacking area and other details are chestnut specific provisions: 1, cooling storage Chestnut Food Storage Room,

, the storage temperature should be maintained at 0C ± 0.5C.. 2, normal chestnut directly into the library,

, in order to reduce the temperature fluctuations, per day, the cumulative compressor run time of less than 16 hours of downtime each time with no more than 3 hours 3, to extend the running time of refrigerator, cold storage temperature reaches the predetermined minimum temperature, cooling should not stop but rather by reducing the cooling capacity to meet the balance of cold cold 4, the storage temperature in the 0c to 0,5 c, press the evaporation area and the warehouse area 1 to 1 ratio of work put into the evaporator, when the storage temperature decreased after the O ~ C the following shall be 0.5 to 1 ratio to reduce the work of the evaporator 5, the class asked refrigerated cooling, the cooling fan of the total air volume of each hours shall be not less than 4O times the volume of the Treasury. 6, do not ask such refrigeration cooling, the Treasury should be at least 1O per hour times (Treasury volume) of the circular air flow. In recent years, we Shouzhu chestnut before, with special attention to make 7, the normal stacking of cargo space Q chestnut flow rate of less than male \ additional temporary fan 8, in order to maintain a relative humidity of the Treasury at 85 = 5 between the refrigerant evaporation temperature and the temperature difference between the Treasury must be controlled at 5 ℃ ~ 8 ℃ range. 9, normal chestnut direct storage, the passage of a filling volume of each no larger than 40kg. 10, Chestnut cooling-off period, you must use the mat board positions stacked, (1.25m of the mat board positions) can only put 4 on each package must be no gaps between each stacking height of not more than 6 sacks, each of two must be added between the mat board positions. Chestnut bag after the temperature dropped to 4C the following in order to shift again turning the heap pile high. We operate according to the above, the chestnut of good quality, such as the recent two years storage of chestnut by our company, the natural loss rates are below 2, mildew and other diseases not found i can say that this method of storage for the chestnut leech lays a good Dong Dong Dong basis of? boxing Dong Dong Dong Dong Dong Dong Dong Sung Wing translation to translation ÷ ÷ Rong Dong Dong Dong Dong Dong Dong Dong Chong Chong Chong Dong Dong Dong Dong Chung Dong Colombian} measures Dong Chong Chong Chong Chong Chong Chong Dong New refrigerated trucks ● Low Temperature Physics, Russian Academy of Sciences of the pilot plant and the state Department of Transportation Wei Teka car jointly developed a pilot plant nitrogen cooling system with new refrigerated trucks. Frozen in liquid nitrogen injected into the compartment, rapid cooling of liquid nitrogen to make the goods and the formation of an inert gas atmosphere around it, not only to control the goods have saved the metamorphic process, and can keep the vegetables, fruits, meat and fresh dairy products, improve food value.

, \ 12 (1996), solar-powered refrigerator too long ago, the Romanian experts developed a new type of cooling device. It is compressed using solar energy to the ammonia container filled with the energy within the project, through the energy conversion system that allows evaporation of ammonia, and then the water cooling system, resulting in the cooling device to obtain cooling effect. This method refrigeration, coolers every day and night to make access to 8 ~ 10kg of artificial ice, may be sufficient protection to the low-temperature refrigeration needs. The refrigeration equipment available to geologists, biologists and scientific research and general home use. It not only has beautiful appearance, small size and characteristics, and cooling process is simple, economical, convenient,
