200 ton Provincial Grain Reserve Project in Danling County, Sichuan Province
one hundred and eighty
1. Two grain storage depots will be built, one is - 20 ℃ and the other is - 35 ℃. The temperature can be adjusted freely;
2. Management needs to meet the centralized control;
3. Under the premise of controlling the cost, the scheme and equipment with high efficiency and energy saving are selected;
4. Meet the main requirements of urs document.
Cold storage scheme:
1. The total area of the - 20 ℃ freezer is 150 m2 / volume is 645 m3; the total area of - 35 ℃ freezer is 35 m2 / volume is 123 m3.
2. The refrigeration system is equipped with two sets of 30HP fujihao piston compressor units (including solenoid valve, pressure controller, etc.), which have large refrigeration capacity, high cost performance, safety and reliability.The cold storage is equipped with two sets of Zhejiang Kaidi dj-300 series high-efficiency strong air coolers. The fans are stable in operation, low in noise and long in air supply distance, which make the cooling speed in the storage fast, greatly enhance the defrosting effect, increase the rapid convection circulation, so as to achieve the temperature uniformity in each corner.
3. In the aspect of storage board, both the quick-frozen warehouse and the frozen warehouse adopt 150 mm polyurethane double-sided color steel plate insulation board. The insulation board has the characteristics of moisture-proof, waterproof and fire-proof, and the flame-retardant standard is B2. Thus, it can ensure the stable low-temperature environment of the cold storage and greatly reduce the later operation cost.
4. The temperature control system adopts the original imported automatic temperature control system. The control system has the functions of automatically adjusting the temperature in the warehouse, and has the functions of temperature and humidity alarm, data recording, mobile phone client monitoring, etc.
