Micro Brewery Malt Feeding Solution

In microbreweries, in order to save labor, some brewers require augers and silos to transfer the milled malt to the malt vat. Typically, the connections are as shown below.
The silo/hopper is mounted above the wort tank and is connected to a hydromixer.
Thus, the brewer can grind the malt in advance and store the ground malt in the hopper and feed it to the grains at once. It ensures that all the grains start fermenting at the same time.
Since the silo increases the total heat of the brewing room, the ceiling should be high enough to accommodate it.

However, there are times when the ceiling is limited, so the above solution is not suitable.
We need to remove the hopper from the top of the sugaring tank to reduce the height of the sugaring tank.
We need to place a hopper on the floor.
The cost would be higher because an additional propeller would have to be added.
