The refrigerated truck entering the urban area has always been a problem to be solved. It requires the green pass of the urban area. The current traffic management policy sets many restrictions and obstacles for the operation of the freight refrigerated truck , and it is for the enterprises engaged in the production and sales of cold chain food. It's troubled and burdened. Many customers are unable to complete the city's green pass. Not only is the qualification review of the documents cumbersome, but the truck's pass is issued on a pro-rata basis. In response to this problem, members of municipalities and municipalities also participated in the project and actively used policy guidance to improve the existing management model. It was mentioned that “urban distribution and refrigerated trucks have public attributes and are part of public transport, and the marketability of the logistics industry should be restored. Market-oriented and service-based." The municipal traffic commissions have commissioned relevant departments to carry out optimization research on the city’s road traffic management policies. Based on this, they have coordinated with the public security and other relevant administrative departments to further adjust and optimize the management system for issuing freight passes. At present, there have been many acts of forging counterfeit passes. China has never issued a unified "Green Pass Pass". Any freight vehicle that enjoys the "Green Passage" policy for the transport of fresh agricultural products must not use the "Green Pass" Pass as a living item. For the certification of agricultural product transport vehicles, the preferential policies must be obtained by loading the goods or manifests and passing through the toll gate according to the prescribed lanes. Any vehicle that is obviously illegally loaded, refuses to pass a lane or refuses to accept inspections will no longer enjoy the "green channel" preferential policy. Drivers and drivers need to pay attention: 1. Not all highways in the provinces and cities have green passages, and some newly built expressways do not have any, so please consult in advance before you travel. 2. The free passage of the green passage is not to exceed the limit. The limits that cannot be exceeded are different for each province and city. Some do not exceed 10%, and some may be less. There are many types of fresh produce, seafood is also included, and frozen pork is not. In addition to meeting the requirements of the product, the green channel must be driven according to the prescribed route.

Centrifugal Fan :
To prevent damage to the grain caused by the increase in temperature and humidity, ventilation is required. This operation is done by the aeration fan mounted at the bottom of the silo. The body of the aeration fans are made of high quality galvanized steel sheets with a long life and very resistant to corrosion. All parts of the body are connected to each other by nuts and bolts. Exhaust air flow rate and pressure and electric power technology is calculated based on the capacity, height and type of grain stored in the silo.
Vents:
roof vents are designed to carry out the warm air from the silo and during this process to prevent any object to enter inside the silo.
