  • Process for the dosing and transfer of a granular product and corresponding installation
    Patent number: 4749312
    Abstract: A granular product to be dosed is introduced at the same time as a transfer liquid into a dosing chamber below a retaining grid, provided in the upper part thereof. The measurement of the pressure upstream of the dosing chamber makes it possible to detect the arrival of the product level with the grid and to stop the introduction thereof. An inverted U-shaped pipe forming a syphon then ensures the transfer of the dosed product into a tank, when the compressed air is injected into the dosing chamber above the grid.
