Description

DESCRIPTION Frost test system for plant tissues and organs Technical Area Meet; such as computer + datalogger, datalogger, computer + multimeter or multimeter computer-device combinations or only plant tissue and It is related to the frost test system for the organs.

State of the Art Today, it is known as the thermoelectric module (TEM) tray (thermoelectric modules tray). The current model has a width, height and height of 23 cm x 33 cm x 5.5 cm and 6 mm The table is made of thick PVC and 23 made of the same material (ßmm PVC) It consists of a cover with dimensions of x 33 cm. 10 wells (width, length and depth measurements, respectively; 40mm x 40mm x 15mm. edge thickness 6 mm) and this 40mm x 40mm x 3mm thermoelectric module (TEM) in 9 of the wells are available. In 1 well in the middle of the table, the temperature thermistor (or thermocapillary). The voltage outputs from the thermoelectric modules are connected by a connector (at the It is transmitted to the datalogger (or multimeter) via at least 18 pins, preferably female type.

The temperature data coming from the thermistor (or thermocapillary) is direct (to the connector). without being connected) to the datalogger (or multimeter). On the table and cover, There are holes in the test chamber to ensure heat circulation.

In the current model, plant tissues are collected in nine wells on a plate. Thermoelectric modules (TEM) are placed on the After the table and/or several tables are placed in the temperature-adjustable test chamber Frost test is performed according to any connection application.

Plant tissue or tissues placed on the TEM (one or more samples can be placed) They produce heat exothermically while freezing. The generated heat heats one surface of the TEM. This is warming up It creates a temperature difference between the two surfaces of the TEM, this difference is the electrical voltage (millivolt) of the TEM*. causes it to produce. This voltage value produced can be used with any of the connection applications. datalogger, multimeter or saved to the computer. At the same time, the middle of the table With the help of the thermistor (or thermocapil) in the well on the temperature is recorded. The middle of the table at the moment when the generated electrical voltage is recorded. By looking at the temperature value coming from the thermistor (or thermocapillary) located in the The temperature at which death occurs in the tissues is determined.

The problems observed in the current model are; Problem 1: In the current model, the cover is placed on the table and fixed to the table with bolts. This In this case, the flexibility of the PVC material, the unbalanced tightening of the bolts and the tightness of the cover. The edges of the cap and the wells of the thermoelectric module are connected to each other due to the associated stretches. they are not in full contact and heat leaks occur from the contact surfaces. lsi leaks cause fluctuations in the electrical current values of the thermoelectric module.

These fluctuations also complicate the analysis of the data.

Problem 2: Fixing the covers to the table with Bolts and ensuring that the table and cover contact during this process It is necessary to try to tighten the bolts evenly in order to perform it properly. It also causes time and labor losses in the model.

Problem 3: Frost tests on plants are carried out in special test circles. Fully set the temperature The internal volumes of these test circles are kept small in order to ensure Therefore the test In order to use the circles more effectively, there are quite a lot of `examples' inside. must be placed. Width, height and height values are 23 cm x 33 cm x 5.5 cm, respectively. 9 thermoelectric module wells and one thermistor well on the current model are available. In this case, there are only 9 samples in a tray, independently of each other. can be analysed. The low number of TEMs (9 units) of the current model are independent of each other. As a result, it eliminates the possibility of working with more samples at once. This situation More than one sample is placed on a TEM to overcome this. In this case too Confusion occurs in the data obtained from TEM. from a TEM Which of the many data belongs to which 'sample' on that TEM cannot be determined. On the other hand, data occurring at the same time can cause data conflict. causes problems and it becomes difficult to interpret the data. 1 on each TEM in the previous system setting an example solves the problem, but eliminates the possibility of working with too many examples. removes. For this, it is necessary to increase the number of TEM trays and to use larger volumes or there is a need to use more test circles.

Problem 4: In this case, the cost of setting up the infrastructure increases and larger volumes or more tests are required. cabins are needed.

As a result, due to the above-mentioned negativities and existing solutions Due to the inadequacy of the subject, it was necessary to make an improvement in the related technical field.

Purpose of the Invention The invention is a new opening in this field, different from the structures used in the current technique. It aims to reveal a structure with different technical features that bring

The primary purpose of the invention is; cover size, structure and fixing bolts of the current model. To prevent heat leaks due to lack of contact caused by not tightening evenly. to reduce the size of the cover and to apply a skid system to the edges of the cover. This In this way, there will be no temperature changes in TEM wells and data fluctuations will be minimized. data analysis will be facilitated.

It is an object of the invention when, in the present model, the caps are closed with Bolts. and to ensure that the loss of labor is eliminated with the sliding cover system.

Another object of the invention is that the current model has a small number of TEMs on a single tray, large number of samples due to the ability to test fewer samples in a test circle to meet the need for larger volumes or multiple test chambers for testing To realize the use of more thermoelectric modules on a table.

For example, in one of the common test circles in the current model, a total of 4 trays at once While a total of 36 independent samples can be tested safely, the subject of the invention In the system, a total of 160 independent samples were tested on 4 trays in the same test circle. can be done.

Another object of the invention is to have a greater number of TEMs on a table, reduce infrastructure costs by reducing the volume or number of test chambers needed is to make it fall.
