Embodiment 1

[0031] Such as figure 2As shown, the stone mill of the present invention comprises an upper millstone 1 and a lower millstone 2 carved with stones, a short vertical shaft 3 is fixed at the center of the lower millstone 2, a shaft sleeve 4 is arranged at the center of the upper millstone 1, and the shaft on the upper millstone 1 Cover 4 is socketed downwards on the short vertical shaft 3 on the lower millstone 2, so that the upper millstone 1 can rotate on the lower millstone 2, and can prevent the upper millstone 1 from slipping out of the lower millstone 2 during the rotation process. The top surface of the lower grinding disc 2 is a concave surface, and the bottom surface of the upper grinding disc 1 is a convex surface, and the gap space between the two is combined to form a grinding chamber. There is a blanking hole 5 on the upper grinding table 1, and the lower opening of the blanking hole 5 leads to the grinding chamber of the stone mill, and the wheat falling from the ...

Embodiment 2

[0035] A stone-milled flour processing technology is carried out in the following steps:

[0036] a. Cleaning and removing impurities: cleaning the raw grain to remove various impurities;

[0037] b. Moisturizing: According to the different types of raw grains, for hard wheat, the moisture content of the wheat is 13-20%, and the time of moisturizing is 17-25 hours; for soft wheat, the moisture content of the wheat is 13-16.5%, and the time of moisturizing is 13-17 hours Hour;

[0038] c. Grinding and milling: Utilize the stone mill of the present invention for grinding, the grinding speed is 15 rpm, the water content in the flour is controlled at 12.5-13.5, and the flour fineness is controlled at 70-160 orders. Grinding and milling to 6 times can meet the standard requirements of grade flour.

[0039] The present invention uses a special stone mill to process flour, low-speed grinding, and low-temperature processing, which avoids the damage of starch chains and the destructi...

Abstract

The invention relates to a stone mill and a stone mill flour processing process. The stone mill comprises an upper mill disc and a lower mill disc, wherein a feeding hole is formed in the upper mill disc; the bottom surface of the upper mill disc and the top surface of the lower mill disc form milling surfaces; equal fan-shaped areas are formed on the milling surfaces along with the circumferences of the mill discs; a plurality of parallel and contour obliquely-toothed milling edges are carved in each fan-shaped area. Through the stone mill, peel layers and germs of wheat can be peeled quickly and smoothly; seeds of the wheat can be effectively crushed, so that cell walls of the wheat can be protected completely; nutrient substances are not oxidized; the loss of the nutrient substances in the process of milling flour can be reduced; the flour milling efficiency can be improved; rotation speeds of the milling discs can be reduced; the flour milling temperature can be reduced; the loss of the nutrient substances and microelements can be reduced; the flour processed by the stone mill and the processing process is excellent in quality, pure in taste and rich in wheat fragrance.

Description

technical field [0001] The invention relates to a flour processing device and a flour processing technology, in particular to a stone mill and a stone mill flour processing technology. Background technique [0002] Modern flour processing enterprises, due to the development of mechanization and scale, currently use mechanized milling equipment for flour processing. Milling equipment mainly includes milling machine, square sieve, flour cleaning machine, bran beating machine and flour feeding machine, etc. The mill uses centrifugally cast steel rollers for fine grinding, and the leather mill adopts orderly arranged steel tooth rollers for high-pressure, high-pressure, large-scale powder extraction, and the mill operates at high speed, high temperature, and speed It is 500-800 rpm, and the temperature can reach about 120°. Because the steel roller of the flour mill grinds too strongly and the grinding temperature is too high, a large amount of nutrients such as protein in the...
