When the weight value recognized by the weight sensor 320 is less than a set weight value, the control unit 500 maintains the discharge unit 330 in a closed state. Thereafter, if the weight value recognized by the weight sensor 320 is a set weight value, the control unit 500 opens the discharge unit 330 and stores the food in the food weight measurement unit 300 into a food packaging container 10 ).

Here, the food packaging container 10 may be moved to the lower portion of the food weight measurement unit 300 through the food packaging container moving unit 400. The food packaging container 10 is moved to the lower portion of the food weight measurement unit 300 through the conveyor 410, and may be aligned at an exact position through the stopper 420 and the cylinder 430.

The food quantitative supply apparatus using the screw supply method according to the embodiment of the present invention described above has the following effects.

The food quantitative supply apparatus using the screw supply method according to an embodiment of the present invention may adjust the supply speed by controlling the rotation speed of the rotating screw shaft according to the weight of the food. This has the advantage of reducing food loss and supplying food with a set weight to the food packaging container at a uniform time.

In addition, the food quantitative supply device using the screw supply method according to an embodiment of the present invention can quickly supply food by increasing the food supply speed in the initial food supply stage by controlling the rotation speed of the rotating screw shaft according to the weight of the food. In addition, there is an advantage in that food can be accurately supplied by a set weight by reducing the food supply speed in the later food supply stage.

The food quantitative supply device using the screw supply method according to an embodiment of the present invention has a uniform discharging means such as a horizontal stirrer including a first stirring blade and a second stirring blade, so that food is uniformly distributed across a plurality of rotating screw shafts. Can supply. Accordingly, there is an advantage in that food can be supplied to a plurality of food packaging containers at a uniform time, and work efficiency can be improved by reducing a time difference in which food is supplied to a plurality of food packaging containers.

In the above, although the present invention has been described in detail with reference to a preferred embodiment, the present invention is not limited to the above embodiment, and various modifications may be provided within the scope of the present invention. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims.
