It will be understood that the spatially relative terms are intended to encompass different orientations of the object in use or operation in addition to the orientation depicted in the figures. For example, if the items in the figures are turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the elements or features.

The inventor researches and discovers that the granular wax is directly chopped for odor detection in the prior art, on one hand, the contact area of the granular wax obtained in the mode and air is limited to increase, and the sufficient and quick release of the odor is not facilitated; on the other hand, the size of the granular wax obtained by directly cutting the granular wax is not easy to be uniform, and the shape difference is large; the individual difference of the granular wax to be detected is easily caused, so that the accuracy and the stability of the result of the subsequent odor detection are influenced.
The inventor also finds that the volatilization effect of the odor causing substances of the flake granular wax obtained by the scraping blade of the block-shaped wax to be detected is better than that of the granular wax obtained by directly cutting the granular wax, but if the granular wax is directly pressed into the block-shaped wax, the density and the hardness of the granular wax are greatly different from those of the original granular wax, so that the accuracy of the subsequent odor detection is seriously influenced. On the other hand, if the granular wax is melted into a liquid state and then naturally cooled and solidified, although the viscosity, density and hardness of the obtained block wax are the same as those of the granular wax, in the heating and melting process of the granular wax, a large amount of odor-causing substances of the block wax are volatilized, so that the components of the granular wax to be detected are changed, and the solidified block wax cannot be used for odor detection.
The method comprises the following steps of melting granular wax into a liquid state, naturally cooling and solidifying the liquid granular wax into block-shaped wax, and measuring the penetration degree of the granular wax to be detected so as to obtain the physical properties such as density, hardness and the like of the granular wax; the penetration degree of the molten solidification wax in the embodiment of the invention is measured after the granular wax is melted into liquid state and then naturally cooled and solidified into block wax, and the penetration degree of the molten solidification wax to be detected is equal to the penetration degree of the granular wax to be detected.
After the property data exist, the pressure value required for pressing the granular wax into the blocky wax to be detected can be obtained; when the penetration degree of the granular wax pressed into the block-shaped wax is consistent with the penetration degree of the block-shaped wax obtained after the granular wax is melted into liquid state and then naturally cooled and solidified, the pressure value of pressing the granular wax into the block-shaped wax is the appropriate pressure value.
Furthermore, in order to enable the pressed blocky wax to be detected to be well adhered into a whole, in the embodiment of the invention, the environmental temperature of the pressed blocky wax to be detected can be set, specifically, the adhesion degree between granular waxes can be directly influenced by the temperature of the environmental temperature, and the pressed blocky wax to be detected can be well adhered into a whole by properly adjusting the environmental temperature on the premise of not volatilizing odor substances of the granular waxes as far as possible, so that the pressed blocky wax to be detected is more suitable for a doctor blade, and the accuracy of subsequent odor detection is further improved.
Based on the above recognition, the pretreatment system for granular wax odor detection provided by the embodiment of the invention is used for realizing a specific pretreatment method for granular wax odor detection; referring to fig. 1, the pretreatment method for detecting granular wax smell specifically includes:
s11, acquiring property attribute data of the granular wax to be detected; the property attribute data comprises the melting point of the granular wax to be detected and the penetration degree of the solidified granular wax after melting;
s12, determining a corresponding appropriate environmental temperature value and an appropriate pressure value according to the property attribute data of the wax to be detected;
when the penetration degree of the granular wax pressed into the block-shaped wax is consistent with the penetration degree of the block-shaped wax obtained after the granular wax is melted into liquid state and then naturally cooled and solidified, the pressure value of pressing the granular wax into the block-shaped wax is the appropriate pressure value.
Furthermore, in order to enable the pressed blocky wax to be detected to be firmly adhered into a whole and avoid looseness, in the embodiment of the invention, the environment temperature for pressing the blocky wax to be detected can be set, specifically, the adhesion degree among granular waxes can be directly influenced by the environment temperature, and the pressed blocky wax to be detected can be better adhered into a whole by properly adjusting the environment temperature on the premise of not causing volatilization of odor substances of the granular waxes as far as possible, so that the pressed blocky wax to be detected is more suitable for scraping blades, and the subsequent accuracy of odor detection is further improved.
In the embodiment of the present invention, the corresponding suitable ambient temperature value and the suitable pressure value may be calculated and predicted according to the melting point of the granular wax by using a prediction model, specifically:
the proper environment temperature value in the embodiment of the invention is the temperature value required for adhering the granular wax in the pressed blocky wax to be detected into a whole under a specific pressure value.
In practical applications, the method for determining the suitable ambient temperature value may specifically include:
a plurality of pellets each having a different melting point were obtained as first test pellets, and the operation for each first test pellet was as follows:
s101, after the melting point value of the first test granular wax is determined, pressurizing the first test granular wax at a specific pressure value under different environmental temperatures; determining an environment temperature value required by bonding the first test wax particles after being pressed into a block shape as an appropriate environment temperature value;
firstly, a specific pressure value can be set as a reference, and the adhesion degree of the blocky wax after the first test granular wax is pressed is respectively observed at different environmental temperatures; the lowest ambient temperature at which sticking together is possible is determined as the suitable ambient temperature value. In practical applications, the specific value of the specific pressure value may be set to 2MP-3 MP.
S102, taking the suitable environmental temperature value of each first test granular wax as a dependent variable data set, and taking the melting point of each first test granular wax as a self-variable data set;
the appropriate ambient temperature value of the first test wax obtained in step S101 is used as a dependent variable data set, and the melting point of each first test wax is used as a self-variable data set.
S103, model training is carried out according to the dependent variable data set and the independent variable data set, and an environment temperature prediction model for predicting the proper environment temperature value through the melting point of the granular wax is generated.
By assigning appropriate test data and training data for model training, an ambient temperature prediction model for predicting an appropriate ambient temperature value by the melting point of the wax particles can be generated.
Therefore, after the environmental temperature prediction model is generated, the corresponding appropriate environmental temperature value can be calculated by knowing the melting point of the wax to be detected.
Then, the proper pressure value in the embodiment of the invention refers to a pressure value which is required by the preset penetration degree and is used for pressing the granular wax to be detected into the blocky wax to be detected under the proper environment temperature value; it should be noted that the preset penetration in the embodiment of the present invention is also the penetration of the wax to be detected after melting and solidifying.
The specific determination method of the suitable pressure value in the embodiment of the invention may include:
obtaining a plurality of granular waxes respectively having different suitable environmental temperature values as second test granular waxes, and operating each second test granular wax as follows:
s201, after determining the suitable environmental temperature value of the second test grain wax, pressurizing the test grain wax under different pressure values respectively; determining a proper pressure value of the test granular wax according to a pressure value required when the second test granular wax pressed into a block shape reaches a preset penetration;
the second test wax in the embodiment of the present invention may be obtained from the first test wax, for which the appropriate ambient temperature value has been determined, or from the wax for which the appropriate ambient temperature value has been calculated by the ambient temperature prediction model. Similarly, the second test waxes of the present examples each have a different melting point.
Pressing the second test granular wax into block-shaped wax under different pressures by taking the suitable environmental temperature of the second test granular wax as the environmental temperature, and then measuring the penetration degree of the block-shaped wax;
determining a suitable pressure value for the second test wax pellet by needle penetration comparison with a corresponding wax pellet solidified after melting; that is, at a suitable ambient temperature, when the block wax obtained by pressing a certain second test grain wax has the same penetration degree as the block wax obtained by solidifying after melting, the pressure value of the pressed second test grain wax can be determined as a suitable pressure value.
S202, taking the appropriate pressure value of each second test granular wax as a dependent variable data set, and taking the penetration of each test granular wax as a self-variable data set;
the appropriate ring pressure value of the second test wax obtained in step S201 is used as a dependent variable data set, and the penetration of each second test wax is used as a self-variable data set.
And S203, performing model training according to the dependent variable data set and the independent variable data set to generate a pressure prediction model for predicting the appropriate pressure value of the particle wax according to the particle wax penetration.
By performing model training by assigning appropriate test data and training data, a pressure value prediction model for predicting an appropriate pressure value thereof by the penetration of wax pellets can be generated.
Therefore, after the pressure value prediction model is generated, the corresponding appropriate pressure value can be calculated as long as the penetration degree of the wax to be detected is known. The penetration of the wax pellets to be tested can be obtained by melting and solidifying the penetration of the wax pellets.
After the environmental temperature prediction model and the pressure value prediction model are generated, the corresponding appropriate environmental temperature value and the appropriate pressure value can be calculated according to the melting point and the penetration degree of the wax particles to be detected.
S13, pressurizing the granular wax to be detected at a proper pressure value at a proper environment temperature to generate blocky wax to be detected;
after the proper environmental temperature and the proper pressure value of the wax granules to be detected are determined, the wax granules to be detected can be pressed into the corresponding blocky wax to be detected.
And S14, scraping the blocky wax to be detected to generate the wax to be detected to be a thin sheet.
Then, the block-shaped wax to be inspected needs to be scraped to generate a thin-sheet wax to be inspected suitable for odor detection.
In the pretreatment method for the granular wax odor detection, in order to obtain a granular wax product suitable for odor detection, the granular wax is firstly pressed into block wax to be detected, and then a flaky wax to be detected is obtained by a scraping blade; in order to keep the properties of the obtained flake wax to be detected consistent with the original granular wax, the pressed blocky wax to be detected needs to have certain adhesion, and the hardness and the density of the blocky wax to be detected can be consistent with those of the original granular wax. Thus, the proper environmental temperature value and the proper pressure value for pressing the granular wax to be detected can be determined according to the property attribute data of the granular wax to be detected; and pressing the granular wax to be detected at an environment temperature with a proper environment temperature value to form a blocky wax to be detected by a proper pressure value, and scraping the blocky wax to be detected into the flake wax to be detected.
