Description

Technical Field

[0001] The invention relates to the technical field of animal specimen preparation, in particular to a method for preparing a beetle specimen. Background Art

[0002] Beetles are a collective term for insects in the order Coleoptera. Currently, there are over 380,000 beetle species worldwide, accounting for 40% of the total insect population, making them the most numerous group of insects. Their rich ecological diversity makes them play a vital role in both terrestrial and freshwater ecosystems.

[0003] By making beetle specimens, the beetle's morphological characteristics can be preserved intact, providing a physical basis for the accurate identification and classification of species, and for teaching demonstrations.

[0004] Existing beetle specimen preparation techniques often use alcohol or ethyl acetate for disinfection, killing, or preservation. However, alcohol deteriorates the connective tissue of beetles, making them hard, coarse, and less pliable, making them prone to breakage during preparation or storage. Ethyl acetate also destroys proteins, causing the beetles to release oil, affecting their ultimate preservation and aesthetic appeal. Large beetles also require the removal of their internal organs, a process that inevitably involves some degree of damage to the specimen. Summary of the Invention

[0048] The present invention provides the following embodiments

[0049] Example 1: This embodiment of the present invention provides a method for preparing a beetle specimen, such as Figure 1 As shown, including:

[0050] Step S1: freeze-dehydrating the beetle to be prepared as a specimen;

[0051] Step S2: thawing the beetles frozen in step S1 in cold water;

[0052] Step S3: placing the beetle obtained in step S2 into warm water to soften the beetle's joint tissue;

[0053] Step S4: drying the beetles obtained in step S3 through a drying device.

[0054] Preferably, the beetles to be prepared into specimens are dying beetles or dead beetles.

[0055] Preferably, the freezing time in step S1 is 2 weeks;

[0056] The freezing temperature in step S1 is -20°C to -30°C.

[0057] Preferably, the drying time in step S4 is 1 to 7 days, and the drying temperature is 30° C. to 50° C.

[0058] Preferably, the water temperature in step S2 is 5°C to 20°C, and the water temperature in step S3 is 30°C to 40°C.

[0059] The above parameters can be set to different ranges according to different types of beetles;

[0060] The beneficial effects of the above technical solution are as follows: the present invention does not use any chemicals, but uses low-temperature freezing to treat dying beetles or dead beetles. Low-temperature freezing for a sufficient time can physically deteriorate and dehydrate the protein, and the internal organs or other tissues in the body will eventually become dried meat. There is no need for disassembly or preservation, the safety of preparation is improved, and the final ornamental value is improved.

[0061] The present invention addresses the following issues raised in the background art: alcohol deteriorates the connective tissue of beetle carcasses, causing them to become hard and coarse, losing their toughness and making them prone to breakage during preparation or storage. Ethyl acetate also destroys proteins, causing the beetle carcasses to release oil, which affects their final preservation and aesthetic appeal. Large beetles require viscera removal, a process that inevitably involves some degree of damage to the specimen.

[0062] Example 2, based on Example 1, step S4 includes:

[0063] Step S41: obtaining the required drying temperature and required drying time of the current beetles to be dried (it can be determined based on testing that the current beetles to be dried have better drying quality at the current required drying temperature and required drying time);

[0064] Step S42: Based on the current required drying temperature of the beetles to be dried and the current temperature of the drying area of the current drying equipment, the predicted temperature stabilization time corresponding to the current beetles to be dried of the current drying equipment is determined; a mapping table corresponding to the current drying equipment is preset: the temperature of the drying area before the current set temperature of the drying area is set - the current set temperature of the drying area (taken as the current required drying temperature of the beetles to be dried) - the predicted temperature stabilization time (the temperature is stable within the preset range of the current set temperature of the drying area (which can be ±0.5°C)), the mapping table is obtained based on the test when no drying objects are placed in the current drying equipment, and can also be obtained based on the heat calculation model; the present invention can be based on constant temperature oven drying, and the drying area in the constant temperature oven (including the current beetles to be dried) The temperature in the area where the beetles to be dried are placed can be detected based on a third temperature sensor (the current area where the beetles to be dried may not actually be provided with a third temperature sensor, or may be provided with only one to two third temperature sensors). The constant temperature oven is used to control the temperature of the drying area in the constant temperature oven to be stable within a preset range of the set temperature of the constant temperature oven. The working principle of the constant temperature oven is as follows: first, a high working power is set to heat the drying area until the temperature of the drying area reaches a preset range corresponding to the current set temperature of the drying area (the average detection value of the third temperature sensor is within the preset range corresponding to the current set temperature of the drying area, and the constant temperature oven is controlled based on the average detection value of the third temperature sensor). Then, the working power is continuously adjusted so that the temperature of the drying area is stable within the preset range corresponding to the current set temperature.

[0065] Step S43: performing a drying test on the current drying device based on the required drying temperature of the current beetles to be dried and the predicted temperature stability time corresponding to the current beetles to be dried of the current drying device to determine whether the current drying device can dry the current beetles to be dried;

[0066] When the current drying device is capable of drying the current beetles to be dried, determining a target setting temperature of the current drying device corresponding to the current beetles to be dried;

[0067] Step S44: When drying the current beetles to be dried, the setting temperature of the current drying equipment is controlled to be set to the target setting temperature of the current drying equipment corresponding to the current beetles to be dried, and the current beetles to be dried are dried for the required drying time.

[0068] Step S43 includes:

[0069] Step S431: Arrange a plurality of first temperature sensors at different locations of the current drying device's placement area for the current beetles to be dried (the first temperature sensors may be removed during actual drying of the current beetles to be dried), then set the current set temperature of the current drying device to the required drying temperature of the current beetles to be dried, and perform a drying test. When the drying test reaches the predicted temperature stability time corresponding to the current beetles to be dried, control the first temperature sensors to start detection, and then continue the drying test for the first set time (which may be 10 minutes).

[0070] Step S432: Based on the detection results of the first temperature sensors during the drying test, a time-detection value variation curve corresponding to each first temperature sensor is constructed, and the time-detection value variation curve corresponding to each first temperature sensor is divided into N first curve segments at a first preset time interval (which may be 20 seconds), and each first curve segment is numbered; the abscissa of the time-detection value variation curve is time, and the ordinate is the detection value of the corresponding first temperature sensor corresponding to the abscissa time;

[0071] Step S433: Calculating the drying uniformity evaluation value corresponding to the time of each first curve segment of the current placement area of the beetles to be dried and the actual equivalent temperature value Q of the current placement area of the beetles to be dried based on step S432;

[0072] Step S434: When the actual equivalent temperature value of the current placement area of the beetles to be dried is greater than or equal to the preset equivalent temperature value corresponding to the current beetles to be dried (which may be 0.8), the target setting temperature T of the current drying equipment corresponding to the current beetles to be dried is determined based on step S433;

[0073] When the actual equivalent temperature value of the placement area of the current beetles to be dried is less than the preset equivalent temperature value corresponding to the current beetles to be dried, an alarm is issued to remind that the current drying equipment cannot dry the current beetles to be dried.

[0074] The abscissas of the first curve segments with the same number corresponding to all the first temperature sensors are the same (for example, the abscissas of the first curve segment with the number n corresponding to the first first temperature sensor, the first curve segment with the number n corresponding to the second first temperature sensor, ... the first curve segment with the number n corresponding to the Nth first temperature sensor are the same);

[0075] Step S433 is calculated based on the following formula:

[0076]

[0077] W iA is the drying uniformity evaluation value corresponding to the time of the first curve segment numbered i in the current placement area of the beetles to be dried (specifically, the current placement area of the beetles to be dried in the current drying equipment); i3 A is the standard deviation of the average ordinate of the first curve segment numbered i corresponding to all first temperature sensors in the current placement area of the beetles to be dried; i1 A is the maximum value of the average ordinate of the first curve segment numbered i corresponding to all the first temperature sensors in the current placement area of the beetles to be dried; i2 is the minimum value of the average ordinate of the first curve segment numbered i corresponding to all first temperature sensors in the current placement area of the beetles to be dried; σ1 and σ2 are the first uniform correlation evaluation weight and the second uniform correlation evaluation weight, respectively (both values are greater than 0 and less than 1, and can be 0.5 and 0.5, respectively); T0 is the current required drying temperature of the beetles to be dried;

[0078]

[0079] ln is the natural logarithm; W i-1 is the drying uniformity evaluation value corresponding to the time of the first curve segment numbered i-1 in the current placement area of the beetles to be dried (specifically, the current placement area of the beetles to be dried in the current drying equipment); ln is the natural logarithm; e is a natural constant; T i is the average value of the average ordinates of the first curve segments numbered i corresponding to all the first temperature sensors in the current placement area of the beetles to be dried;

[0080] Step S434 is calculated based on the following formula:

[0081]

[0082] T is the target setting temperature of the current drying equipment corresponding to the current beetles to be dried.

[0083] The drying quality qualification rate of the beetle specimens dried by the method of the present invention (the drying quality qualification means that all the drying quality evaluation indicators are qualified (the drying quality evaluation indicators meet the corresponding standard ranges)) is above 98%;

[0084] The drying quality evaluation index is based on any one or more of the following aspects: the degree of dryness of the specimen (which can be judged subjectively by observing the color and texture, and scored from 1 to 5, with 1 being very moist and 5 being completely dry), the morphological integrity of the specimen (recording whether the specimen is deformed or has curled wings, and expressing the normal morphological proportion as a percentage), the weight loss ratio of the specimen (the difference between the initial weight and the weight after drying divided by the initial weight), etc.

[0085] The beneficial effects of the above technical solution are:

[0086] Due to the long operation of current drying equipment, the temperature in some parts of the internal drying area (which may be the area where the beetles to be dried are placed) may be uneven and / or may not reach the preset range corresponding to the set temperature (possibly due to the degradation of the heat transfer performance in some parts), resulting in the drying effect not being able to achieve the set temperature.

[0087] Therefore, in order to ensure the drying quality of the current beetles to be dried, a drying test is performed on the current drying equipment based on the required drying temperature of the current beetles to be dried and the predicted temperature stability time corresponding to the current beetles to be dried of the current drying equipment to determine whether the current drying equipment can dry the current beetles to be dried, so as to ensure that the appropriate drying equipment is selected to dry the current beetles to be dried;

[0088] During the drying test, the current set temperature of the current drying device is set to the required drying temperature of the current beetles to be dried, and the drying test is carried out. When the drying test reaches the predicted temperature stabilization time corresponding to the current beetles to be dried, the first temperature sensor is controlled to start detection, and then the drying test is continued for the first set time. Only when the temperature in the drying area of the current drying device approaches or reaches stability is the test temperature data obtained based on the first temperature sensor, thereby ensuring the reliability of the temperature evaluation data;

[0089] Then, based on the detection results of the first temperature sensors during the drying test, a time-detection value change curve corresponding to each first temperature sensor is constructed, and the time-detection value change curve corresponding to each first temperature sensor is divided into M first curve segments at a first preset time interval and each first curve segment is numbered. Based on the difference state of the average temperature of all first temperature sensors in the same time period (the difference state of the average temperature of all first temperature sensors corresponding to the first curve segment numbered i) Get the temperature difference state W of each first curve (corresponding to a time period) i ; Comparison of the average temperatures of all first temperature sensors within the same short period of time ensures the reliability of the assessment of the temperature difference state;

[0090] Then, based on the average of the temperature difference states of all the first curve segments, we can get Then, the average temperature state is obtained based on the average of the average temperatures of all the first curve segments. The fluctuation state of the temperature difference state of the adjacent first curve segments is obtained Finally, the actual equivalent temperature value Q of the current placement area of the beetles to be dried is obtained by combining the above parameters, and the calculation is reliable;

[0091] When the actual equivalent temperature value of the area where the beetles to be dried are placed is less than the preset equivalent temperature value (which can be 0.8) corresponding to the beetles to be dried, an alarm is triggered to remind the user that the current drying equipment cannot dry the beetles to be dried, and to replace the appropriate drying equipment, thereby ensuring that the appropriate drying equipment is selected.

[0092] The current drying equipment can dry the current beetles to be dried, but the actual equivalent temperature value is different from the ideal actual equivalent value (which can be 0.9-1). At this time, it is necessary to adjust the set temperature of the drying equipment (adjust to the target set temperature of the current drying equipment corresponding to the current beetles to be dried) to ensure the drying effect of the current beetles to be dried.

[0093] Example 3, based on Example 1 or 2,

[0094] Step S1: placing the frozen beetles in a sealed bag or container and then thawing them in a water bath; a second temperature sensor detects the water temperature in the water bath, and a timer is used to time the thawing time of the beetles in the water bath; a control device is electrically connected to the second temperature sensor, the timer, and the temperature control device, respectively, and the temperature control device is used to adjust the water temperature in the water bath;

[0095] Step S2 includes:

[0096] Step S21: Obtain the target thawing water temperature range [T1, T2] and target thawing time of the beetles to be thawed; [T1, T2] may be [15, 16];

[0097] Step S22: adjusting the temperature control device of the water bath so that the water temperature in the water bath reaches the median value B1 of the target thawing water temperature range for the beetles to be thawed;

[0098] Step S22: The beetles to be thawed are placed in a sealed bag or container and then placed in a water bath for thawing, and the second temperature sensor is controlled to perform multiple tests at a second preset time interval;

[0099] During the thawing process, the temperature control device is intelligently controlled based on the second temperature sensor and the timer so that the water temperature in the water bath is maintained within the target thawing water temperature range of the current beetles to be thawed.

[0100] In step S2, the temperature control device is intelligently controlled based on the second temperature sensor and the timer so that the water temperature in the water bath is maintained within the target thawing water temperature range for the beetles to be thawed, including:

[0101] Step S221: First, the temperature control device is controlled to stop working. When the detection value of the second temperature sensor corresponding to the water bath meets the trigger condition for the first time, the actual temperature change rate G1 that initially meets the trigger condition is determined based on the timer value; the trigger condition includes: a first range [T1+0.2(T2-T1), T1+0.3(T2-T1)], a second range [T1+0.7(T2-T1), T1+0.8(T2-T1)]; satisfying the trigger condition means satisfying any temperature range that meets the trigger condition;

[0102]

[0103] B 11 The second temperature sensor detection value corresponding to the water bath reaches the second temperature sensor detection value when the trigger condition is first met; t1 is B 11 The corresponding timer value (the beetles to be thawed are placed in a sealed bag or container and then placed in a water bath and the timer starts timing (the initial timer value is 0));

[0104] Step S222: controlling the temperature control device to operate at the target power corresponding to the current trigger condition until the detection value of the second temperature sensor corresponding to the water bath meets the trigger condition next time;

[0105] Repeat step S222 until the total time the current beetles to be thawed are placed in the water bath reaches the target thawing time of the current beetles to be thawed;

[0106] Among them, when the trigger condition is met for the second time and each time the trigger condition is met after the second time, the temperature change rate to be compensated corresponding to the current time the trigger condition is met is calculated, and the target power corresponding to the current time the trigger condition is met is determined based on the actual temperature change rate when the trigger condition is first met and the temperature change rate to be compensated corresponding to the current time the trigger condition is met.

[0107] The beneficial effects of the above technical solution are:

[0108]

[0109] Determine the target power P1 corresponding to the temperature change rate to be compensated G that initially meets the trigger condition based on a preset temperature change rate to be compensated-target power mapping table;

[0110]

[0111] The second temperature sensor detection value corresponding to the water bath meets the trigger condition for the kth time; t is the second temperature sensor detection value corresponding to the water bath when the difference between the second temperature sensor detection value and B1 is greater than 0 for the first time during the period from the k-1th time when the trigger condition is satisfied to the kth time when the trigger condition is satisfied; k0 for The detection time and The time difference of the detection time; Y k is the actual temperature change rate that meets the trigger condition for the kth time;

[0112] The preset temperature change rate to be compensated - target power mapping table can be calculated based on the test or the heat transfer formula based on the existing technology, or based on the following formula Where c is the specific heat capacity of the water in the water bath, m is the weight of the water in the water bath, and γ is the heat exchange efficiency of the temperature control device of the water bath (the ratio of the heat exchange capacity of the water in the water bath to the input electrical energy of the temperature control device within a certain period of time).

[0113] The thawing effect qualification rate of the present invention (the percentage of beetles that have passed thawing to all thawed beetles) meets 96% or more;

[0114] Thawing effect indicators include: specimen integrity; texture (including hardness, elasticity, toughness, etc.); appearance color, etc.

[0115] The beneficial effects of the above technical solution are:

[0116] Set the trigger adjustment: the first range [T1+0.2(T2-T1), T1+0.3(T2-T1)], the second range [T1+0.7(T2-T1), T1+0.8(T2-T1)]; satisfy the trigger condition, that is, any temperature range that satisfies the trigger condition; when the water temperature in the water bath is close to the limit of the current target thawing water temperature range for the beetles to be thawed, timely adjust the power of the temperature control device to ensure that the water temperature in the water bath is within the current target thawing water temperature range for the beetles to be thawed.

[0117] Because even for the same species of beetles, the heat exchange state of the beetles to be thawed varies due to individual differences and differences in freezing state. Therefore, it is not necessary to set a fixed temperature control device parameter for the same beetle. Instead, the temperature control device is continuously adjusted for each specific beetle to be thawed (after the trigger condition is met) to ensure the thawing effect. Specifically:

[0118] First, the temperature control device is controlled to stop working. When the detection value of the second temperature sensor corresponding to the water bath meets the trigger condition for the first time, the actual temperature change rate G1 that initially meets the trigger condition is determined based on the timer value. That is, the initial temperature drop state of the current beetles to be thawed relative to the water in the water bath is first obtained (reflecting the current heat exchange state between the beetles to be thawed, the sealed bag or container as a whole, and the water in the water bath), and an appropriate P1 is determined (to ensure balance with the aforementioned temperature drop state relative to the water).

[0119] Since the current beetles to be thawed have different thawing degrees, the temperature drop of the water in the water bath is different ( The target power corresponding to the current trigger condition is determined based on the actual temperature change rate when the trigger condition is first satisfied and the temperature change rate to be compensated corresponding to the current trigger condition. This ensures the reliability of the target power adjustment of the temperature control device when the trigger condition is satisfied for the second time and each time the trigger condition is satisfied thereafter.

[0120] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
