One distribution gutter, which is arranged so as to cross over and has a filling port on the bottom wall so as to be located right above the row of buckets, and the filling port of the distribution gutter is opened and closed every time the conveyor is driven for one cycle. After opening and closing means and the filling port of the distribution gutter is closed and before the next opening, the soy milk with coagulant is sufficient to fill the distribution gutter into one bucket in each row. The thing provided with the supply means to supply is known.

[0003]

In the above apparatus, the time for supplying the soy milk to the distribution gutter is between the closing of the filling port and the opening of the filling port during one driving cycle of the conveyor.
This period is extremely short, and a large amount of soy milk must be supplied to the distribution gutter at one time during this short period. Therefore, the liquid surface of the soymilk in the distribution trough may wavy or the soymilk may foam. If filling is performed before the undulation of the liquid surface is cured, quantitativeness for each bucket 1 is impaired, and if filling is performed while foaming, bubbles will be caught in the product and product quality will be impaired. Be done.

An object of the present invention is to provide a soybean milk dispenser / filler for coagulant containing a soybean milk in a dispenser gutter capable of preventing the occurrence of liquid level waving and foaming.
