Description

Rice wet slurry automatic stone mill

technical field

The invention relates to the field of food processing machinery, in particular to an automatic stone mill for rice wet slurry.

Background technique

Fresh rice noodles are traditional convenience foods in southern provinces and cities of my country. The fresh powder is convenient to eat and has a good taste: it is convenient and quick whether it is soup, frying or mixing. Fresh noodles are made of rice and are not extruded. The noodles are wide and thin, and the rehydration speed is fast. It is delicious, soft and moist, smooth and easy to digest. , health, convenience, health care, storage-resistant, low-cost health food in one.

The raw material of fresh powder is rice, and the production process is as follows: wash the rice and grind it into powder, add water to make a paste, steam it in a basket to make it into flakes, and cut it into strips after cooling. The quality of fresh flour has a lot to do with the grinding of rice. In traditional stone mills, the upper disc runs while the lower disc is fixed. When the speed increases, the centrifugal force generated by the upper disc is large, which is inconvenient and difficult when adding grain. The safety is poor; at the same time, the grinding discs of traditional stone mills are generally made of granite. The stone mill relies on the gravity of the upper grinding disc to press on the lower grinding disc. When the grain is added, it wears out faster, and a large amount of stone powder that has been ground off is mixed into the rice milk, affecting the quality of the rice milk. In addition, because the weight of the upper grinding plate is limited, in the process of refining, due to the effect of grain, the upper grinding plate jumps up and down, resulting in impact, high working noise, and large power consumption. When the amount of grain fed increases, the upper grinding plate The grinding disc will not be lifted, and the grinding work cannot be carried out, resulting in frequent shutdown of the stone mill and low work efficiency. Moreover, in a mechanical stone mill, the speed of the grinding disc determines the processing efficiency. If the rotating speed is too slow, the processing efficiency will be affected; if the rotating speed is too fast, the heat generated by the grinding disc will be too large, which will cause some rice milk to be cooked in the grinding disc and become sticky. , is not conducive to the discharge of rice milk.
