Description
Technical Field
the invention belongs to the technical field of measurement, and particularly relates to a grain product measuring method.
Background
the specific volume of bread and steamed bread made from grains is one of important indexes for evaluating the quality of grains, and the specific volume value of the bread and the steamed bread is obtained by measuring the volume and the weight of the steamed bread and obtaining the ratio of the volume to the weight. Therefore, the volume and weight of the bread and steamed bread directly influence the quality of the grains. The weight of the bread and the steamed bread is easy to measure, and accurate numerical values can be obtained by repeatedly using balance weighing. However, the rapeseed displacement method is mostly adopted for measuring the volume of bread and steamed bread. The rapeseed displacement method is to fill a fixed container with rapeseed before measurement, and then pour the rapeseed for use. During measurement, the steamed bun to be measured is placed into the fixed container, the container is refilled with the prepared rapeseeds, the volume of the remaining rapeseeds is measured after the original volume is reached, the volume is the volume of the measured steamed bun, but the volume of the rapeseeds needs to be measured again by other containers, the measurement steps are complicated, errors exist in the measurement process of each step, the more the steps are, the larger the errors are, meanwhile, a flour mill needs to measure a large amount of specific capacity values after different batches of products are made into steamed buns, breads and other finished products through different processing modes every day, the rapeseed replacement method needs to occupy a large amount of time of personnel, and the measurement result has deviation.
The method for measuring the volume of the steamed bun in the prior patent comprises the steps of putting the steamed bun into a waterproof film bag, sealing and vacuumizing, then putting the steamed bun into a container, and fixing the volume to a fixed volume by using water, wherein the volume of the steamed bun is the volume difference between the fixed volume and the volume difference between the added water and a packaging material. Although the method overcomes the prejudice that the steamed bread is not suitable for measuring the volume in water, the method has larger measurement error because the volume of the dried packaging material needs to be measured, the volume of the steamed bread is very easy to change by sealing and vacuumizing, and finally the volume error of the steamed bread is larger. The other method is to wrap the surface of the steamed bun by a preservative film bag, measure the mass of the overflowing water after the steamed bun to be measured is immersed by utilizing the principle of a drainage method, and then obtain the volume of the steamed bun through the conversion of the mass and the volume of the water. Although the method is simple to operate, the steamed bun is not in a very regular shape, and if the surface of the steamed bun is directly wrapped by a preservative film bag for measurement, a large error is generated in measurement of the actual volume of the steamed bun.
