Description
Technical Field

Background
In the field of food processing, steamed bread and bread are two major types of fermented flour products, specific volume is an important parameter index for detecting the quality of the steamed bread and the bread, the specific volume in the steamed bread and the bread reflects the volume expansion degree and the retention capacity of dough, and the specific volume directly influences the appearance, the taste and the tissue of finished steamed bread and bread.
The specific volume of the steamed bread is an index of a wheat cooking quality evaluation test method, and the specific volume of the bread is an important basis for judging the quality index of the bread.
In the current national standards, the contents of specific volume as a main quality judgment and evaluation index are specified in GB/T20571-2006 wheat storage quality judgment rule, GB/T20981-2007 bread, GB/T35991-2018 grain and oil inspection wheat flour steamed bun processing quality evaluation and the like.
The current specific volume determination method is to weigh the mass of steamed bread or bread by a balance and then measure the volume by a steamed bread and bread volume determination instrument, thereby calculating the specific volume. A volume measuring instrument for steamed bread and bread adopts a volume displacement method, and the method comprises the steps of weighing steamed bread or bread to be measured, placing the weighed steamed bread or bread into a volume measuring instrument or a container with a certain volume, adding a small-particle filler (millet or rapeseed) into the container, completely covering a bread sample, fully shaking and filling the steamed bread sample, scraping the filler by using a ruler, taking out the measured steamed bread or bread, pouring the filler into a measuring cylinder to measure the volume, and subtracting the volume of the filler from the volume of the container to obtain the volume of the bread.
The volume measuring instrument is adopted for measurement, and the following defects exist:
the volume measuring instrument used by the volume measuring instrument method is a metal product, and is relatively labor-consuming and time-consuming when the number of samples is large in the actual use process; secondly, the volume measuring instrument is in an opaque state, the situation of uneven filling of particles is easy to occur for steamed bread or bread in an irregular shape, and the measuring result is easy to be inaccurate, so that sufficient shaking is ensured when the volume measuring instrument is used, and the situation of particle leakage filling is reduced to the maximum extent; thirdly, when the volume measurement is finished, the steamed bread or bread to be measured needs to be taken out, because the surface of the steamed bread or bread can inevitably generate moisture or grease, filler particles are easy to adhere to the surface of a sample to be measured, the loss of small particles is caused, and the filler needs to be quantified again when one sample is measured; and fourthly, the use of the filling agent (millet or rapeseed) causes certain grain waste.
In order to solve the above problems, people are always seeking an ideal technical solution.
