The invention discloses a quantitative distributor. The quantitative distributor comprises a rack, a beancurd jelly tank, a beancurd jelly stirring device and a beancurd jelly flat spreading device. A beancurd jelly input pipe is arranged at the tank opening position of the beancurd jelly tank. The beancurd jelly stirring device is arranged at the position close to the tank opening position of the beancurd jelly tank. Distribution space is formed by an upper sealing plate and a lower sealing plate at the bottom of the beancurd jelly tank and is formed at the bottom of the beancurd jelly tank. The lower portion of the beancurd jelly tank is provided with a beancurd jelly outlet. A guiding part penetrates the beancurd jelly outlet and then extends to the position above a lower crawler belt at the inlet position of a subsequent non-moulding-box and a non-wrapping-cloth continuous presser. A quantitative dispatching roller controlled to rotate is arranged in the distribution space, and grooves extending in the axial direction of the quantitative dispatching roller are evenly distributed in the roller face of the quantitative dispatching roller, and the tops of the grooves are closely attached to the adjacent upper sealing plate or lower sealing plate. The beancurd jelly flat spreading device is arranged at the position close to the belt face of the lower crawler belt. By means of the quantitative distributor, automatic beancurd jelly continuous and quantitative distribution can be achieved, the production efficiency is obviously improved, and the product quality is guaranteed.
