Detailed Description
The invention is further illustrated by means of the following examples, which are not intended to limit the scope of the invention.
Example 1
The embodiment provides a method for measuring the volume of food materials, referring to fig. 1, the measuring method includes:
s11, acquiring the initial concentration of the indication gas at an initial time point. The initial concentration is acquired through a gas concentration sensor arranged at the gas outlet of the storage cabin, and the initial time point is a moment after the cabin door of the storage cabin is closed.
S12, charging working gas with a first concentration at a preset charging speed through an air inlet of the storage cabin.
And S13, stopping inflation and recording the inflation time when the current concentration of the indication gas collected by the gas outlet reaches the preset target concentration.
S14, calculating to obtain the food material volume according to the initial concentration, the first concentration, the current concentration, the inflation time, the inflation speed and the storage cabin volume.
Wherein, the opposite sides of the storage cabin are respectively provided with an air inlet and an air outlet. The air inlet is connected with an inflated air source, and the opening of the air inlet can be controlled through an electric control valve. The gas outlet is provided with a gas concentration sensor, and the gas concentration sensor can detect the concentration of the indication gas and also can detect the concentration of the working gas. The storage cabin and the electric control valve have general tightness requirements, and can meet the requirement that gas only flows out through the gas outlet, and the leakage rate is less than 0.5% under normal pressure.
Working principle: by flushing a known concentration (C) into a known volume (V) compartment N ) The concentration (C1) detected at the outlet is equal to or close to the known concentration, indicating that the compartment is completely filled, the time (t) elapsed being proportional to the volume. When food with unknown volume is put into the storage cabin, the volume is correspondingly reduced, so that C1 and C N The time required for equality is also shortened. The volume of food material placed can thus be known from the change in time.
The working gas may be various gases such as nitrogen, carbon dioxide, etc. suitable for being distinguished from the ambient background or the gases emitted by the object itself. The indicator gas may be the same gas as the ambient background or the object itself, such as oxygen, or the indicator gas may be a working gas.
The total displacement time is calculated to be linearly related to the displacement volume.
In this embodiment, the first concentration of the working gas is filled at a preset inflation speed to replace the existing initial concentration of the indicating gas in the storage compartment, and the volume of the food in the storage compartment can be obtained by the replacement volume of the indicating gas (the filling volume of the working gas) under the condition that the volume of the storage compartment is fixed.
In one embodiment, referring to fig. 2, step S14 includes:
s141, calculating to obtain the inflation coefficient according to the initial concentration, the first concentration and the current concentration.
And S142, calculating to obtain the volume of the gas in the cabin according to the inflation coefficient, the inflation time and the inflation speed. Wherein the volume of gas in the chamber is positively correlated with the length of inflation.
S143, calculating to obtain the food material volume according to the storage cabin volume and the cabin air volume.
Wherein the air filling coefficient is an e function, and the initial concentration, the first concentration and the current concentration are related to an index of the e function.
In one embodiment, the measurement method further comprises, while the storage compartment remains empty during the inflation operation:
and calculating according to the initial concentration, the first concentration, the current concentration, the inflation time and the inflation speed to obtain the storage cabin volume.
Wherein, the storage cabin is kept empty in the inflation work, the initial volume before replacement is the storage cabin volume, and the replacement volume is also the storage cabin volume.
The initial volume, the indicated gas concentration and the inflation flow are preset to be used as the basis of calculation. At a certain concentration C N The nitrogen is used as working gas, the volume of the storage cabin is V, the gas filling flow is q, the oxygen concentration C is measured at the gas outlet, and the oxygen concentration C in the original cabin 0 。
Because the time of filling under the inflation amount is longer, the concentration in the process can be assumed to be instantly and uniformly mixed, namely the concentration of the air outlet is equal to the concentration in the cabin. The discharge outlet concentration can be predicted as follows
Wherein V represents the storage compartment volume, q represents the inflation speed, C 0 Represents the initial concentration, C represents the current concentration, C N The first concentration is indicated, and t is the inflation time period.
The integral of the above can be obtained:
the finishing method can obtain:
the method can also be finished as follows:
it is known that the total displacement time is linearly related to the displacement volume.
In one embodiment, the storage compartment volume is expressed using the following formula:
wherein V represents the storage compartment volume, q represents the inflation speed, C 0 Represents the initial concentration, C represents the current concentration, C N The first concentration is indicated, and t is the inflation time period.
In this embodiment, the storage compartment volume may be directly calculated by the storage compartment volume, the inflation speed, the initial concentration, the current concentration, the first concentration, and the inflation time period.
In one embodiment, the following formula is used to represent the food material volume:
wherein V is m Representing food material volume, V representing storage compartment volume, V1 representing compartment gas volume, alpha representing inflation coefficient, q representing inflation rate, C 0 Represents the initial concentration, C represents the current concentration, C N The first concentration is indicated, and t is the inflation time period.
The following is an example of calculating the volume of food material.
The initial oxygen concentration was known to be 21%, the working gas nitrogen concentration was 90%, the end oxygen concentration was known to be 11%,
when the related conditions are set, the method causes
When the storage compartment volume is 20L, the inflation speed is 1.8L/min. The time required to reach the endpoint is:
t＝16.47min。
when the storage cabin is internally provided with a volume V m After the item, its volume is occupied by the item, so the remaining volume V1 in the compartment can be expressed as
V m ＝V-V1；
Since the object volume is unknown, then by measuring the inflation completion time t1, when t1=10 min, the following formula is substituted to be available:
the empty filling time of the known storage tanks is plotted as a reference, as shown in fig. 3.
The volume of the article is obtained rapidly directly according to the nearby value of the inflation completion time.
In one embodiment, the current concentration reaching the target concentration characterizes the working gas filling the storage compartment and completes the displacement of the indicator gas within the storage compartment by the working gas.
In one embodiment, the second concentration of the working gas collected at the gas outlet is used for judging whether the current concentration reaches the target concentration, and if the difference value between the second concentration and the first concentration falls within a preset range, the current concentration reaches the target concentration. If the difference value between the second concentration and the first concentration falls outside the preset range, the current concentration does not reach the target concentration.
