Refiner

Abstract

Disclosed is a pulp grinding machine. The pulp grinding machine comprises a shell, a motor, a separating plate, a communicating rod, a connecting rod, a closing plate, a gear and torsional springs. A grinding disc is arranged in the shell, a feeding inlet and a water inlet are formed in the upper portion of the shell, and a discharging outlet is formed in the lower portion of the shell. The output end of the motor is connected with the grinding disc. A first screen net is arranged in the middle of a first discharging pipe, and one end of the first screen net is fixed to one side of the first discharging pipe through the torsional spring. A second screen net is arranged in the middle of a second discharging pipe, and one end of the second screen net is fixed to one side of the second discharging pipe through the torsional spring. The first screen net and the second screen net are symmetrically arranged about the separating plate. The communicating rod transversely penetrates through the separating plate and is connected with the separating plate in a sliding mode. A rack is arranged on the communicating rod. A blind hole is formed in the middle of the separating plate, the connecting rod is located in the blind hole, one end of the connecting rod is connected with the closing plate, and the other end of the connecting rod is connected with the gear. The gear is meshed with the rack. The closing plate can close the first discharging pipe or the second discharging pipe. The pulp grinding machine can avoid the phenomenon that due to the fact that a filtering opening is jammed by bean residues, the pulp grinding efficiency is affected.

Description

technical field [0001] The invention relates to the field of tofu making devices, in particular to a refiner. Background technique [0002] Tofu is the most common soy product, also known as water tofu. The main production process is one is pulping, that is to make soybean milk from soybeans; the other is coagulation and forming, that is, under the combined action of heat and coagulant, soy milk is solidified into a gel with a large amount of water, that is tofu. When making tofu, first remove the shells and wash the beans, put them in water after washing, soak for an appropriate time, add a certain proportion of water, and grind them into raw soybean milk. Then use a special cloth bag to pack the ground slurry, close the mouth of the bag, squeeze it hard, and squeeze the soybean milk out of the bag. Generally, the pulp can be squeezed twice. After the first squeeze, the bag is opened, put in clean water, and the bag is closed and squeezed again. Among them, the defibrina...

Problems solved by technology

However, during the use of the existing refiner, the middle part of the refiner is easily blocked due to the uneven thickness of the bean dregs produced, which affects the use of the refiner and reduces the efficiency
