Embodiment Construction
[0020] The method for measuring the porosity of distiller's grains of the present invention includes the following steps:
[0021] a. Sampling: Take a sample of distillers' grains with a volume of V1;
[0022] b. Add a non-water-soluble solvent to the vinasse sample until the surface of the non-water-soluble solvent in the vinasse sample is level with the surface of the vinasse sample, and the volume of the added non-water-soluble solvent is V2;
[0023] c. Calculate the porosity Φ of distiller's grains fermented grains according to the following formula: Φ=(V2 / V1)×100%.
[0024] Among them, if a sample of distiller's glutinous rice is put into a sampling container for sampling, the porosity of distiller's glutinous rice may be changed and the accuracy of the measurement result may be affected. In order to improve the accuracy of the measurement results, it is preferable to adopt the following sampling scheme: use a tubular container with open ends for sampling. When sampling, insert ...

Abstract
The invention relates to a method for measuring the porosity of fermented grains and belongs to the technical field of analysis and detection. The technical problem to be solved by the invention is to provide the method for measuring the porosity of the fermented grains. The method for measuring the porosity of the fermented grains comprises the following steps: a, sampling, namely making a fermented grain sample in a volume V1; b, adding water insoluble solvent into the fermented grain sample till the water insoluble solvent in the fermented grain sample is leveled with the surface of the fermented grain sample, and volume of the added water insoluble solvent is V2; and c, calculating the porosity phi of the fermented grains according to an equation: phi=(V2 / V1)* percent. In the measurement method provided by the invention, the steps are simple, the operation is easy, the required instrument and equipment are simple, the measurement speed is high, and the measurement result is accurate. The method provided by the invention is a new approach for measuring the porosity of the fermented grains and has a bright application prospect.
Description
Technical field [0001] The invention relates to a method for measuring the porosity of vinasse and belongs to the technical field of analysis and detection. Background technique [0002] The ratio of the pore volume in a substance to the total volume of the substance is called the porosity of the substance. At present, the measurement of porosity is mainly used to study the structure of rock or soil. There are many methods for measuring porosity, among which gas method and bulk density method are the most widely used. [0003] The gas method uses the principle of gas isothermal exchange and adopts the method of isovolume variable pressure for measurement. This method is easy to operate and is mostly used for the measurement of rock porosity. [0004] The bulk density method uses a certain volume of steel cylinder (called a ring knife, one end is in the shape of a knife, which is convenient for sampling) to obtain samples, and determine the bulk density and water content of the soi...
