The ground,ventilation and recirculation fumigation system,roof of old type warehouse were rebuilt to improve grain storability.

A new type of combination bin discharge grain system for bulk grain in warehouse was developed,which considered the equipment now available in state grain depots.

Some opinions for the common problems in the technology design of grain loading and unloading ,bin filling, aspirating, cooling, fumigating, grain quality checking and delivering sections in warehouse were put forward.

Comparison Test on Energy Consumption of Temperature Decreasing & Ventilation For Different Ventilators In the same Flat warehouse;

On the design of the Vietnamese flat warehouse confined insulation,grain access to warehouses of technology,ventilation,and cooling system for the fumigation experience.

Through observation and comparison of storability and function of the horizontal bin,squat silo and silo,the advantages and disadvantages of the three bins were summed up respectively.

This article puts forward some original views on horizontal bin including covering too large area and many operating problems for the duration of loading and unloading.

The detal of 50 kinds of warehouse measurements were collected.

The ceiling of warehouse was rebuilt for insulation heat,and then mechanical ventilation was tested for low temperature storage.

Recirculation fumigation in new built warehouse were tested.

Methods of preventing from dewing and molding on the surface of grain heap in storehouses;

Following the use of the newly-built grain storehouses,the problems in most granaries have appeared,such as poor the heat insulation performance of the roof and poor airtight in the doors,windows and holes of the storehouse,and the surface temperature of grain bulk is too.
