Title: Suction nozzle for sandy sludge dredger
Inventor: KUBOSAWA MINORU
IPC: E02F3/92
Filed: 1980-08-15
Abstract: PURPOSE: To rapidly release the blocked state of a sludge suction port by a method in which part of blockaders is connected to water stream of fast flow rate, produced by the blocking of the sludge suction port, in such a way as to cause the water stream with part of the blockaders to suck up with high speeds.  
     CONSTITUTION: As soon as blocking phenomenon begins to occur in and near a sludge suction port 4b 1 , water stream introduced from the upper opening 4c 2  of a water suction cover 4c reaches through a water conduit H to a water suction port 4b 2  provided below a nozzle pipe 4b and becomes a high-speed jet stream because the sludge suction port 4b 1  is in nearly blocked state, and the jet streat of water is jetted into the nozzle pipe 4b. If sandy sludge 11a causative of blockade is present in and near the sludge suction port 4b 1 , the snady sludge (a) nearest to the water suction port 4b 2  is first broken and removed by the jet stream, and in the order of (b), (c)...(g), (h), sandy sludge near the sludge suction port 4b 1  is degradated.

This insolubilized protein and the insolubilized saccharide contained in the bean-cured refuse of soybean milk provide palatability with roughness of bean jam cell of its own. Then sugar is added to the bean-curd refuse of soybean milk, allowed to stand until the sugar is sufficiently dissolved, sorbitol in an amount corresponding to 40-60wt% sugar added is incorporated with the bland and the blend is kneaded at 80-100 deg.C. Consequently, the prepared jam is provided with proper smoothness which is another property of existing bean jam besides the roughness of bean jam of its own.
