Soil drying ovenAdopting a dual mode of heating and hot air in a drying oven module, the indoor air flow mode is simulated in a realistic way, that is, the air drying mode is used for soil drying. Dry air is clean hot air that has undergone coarse filtration and activated carbon adsorption. The samples are stored and dried independently in separate rooms, which is clean and avoids cross contamination of the samples; Time saving; Effort saving; Save space; Improve soil drying efficiency and other characteristics.

A soil drying oven can store numerous soil samples in a box. Simulating the indoor air flow pattern inside the box, * air filtration and adsorption technology was sampled. Through external power supply and constant temperature combined for rapid air drying, the pre-treatment of the sample can be completed. The sample is stored and dried independently in separate rooms. Avoiding cross contamination of samples.

　　Soil drying ovenAdopting air heating disturbance technology to simulate indoor air flow patterns and simulate natural dry soil indoors. Dry air is filtered and cleaned through coarse fibers and activated carbon to ensure cleanliness. The sample room is made of 316 stainless steel, and the sample rooms are independent of each other to prevent cross infection of samples, making the soil drying process simple!

The specific usage method is as follows:

(1) Insert the thermometer into the socket

(2) Insert the power plug into the power outlet.

(3) Turn the beginning of the electric heating wire group to position 1 or 2, which can activate the convection of hot air. After the grouping of electric heating wires is started, the red indicator light will turn on.

(4) Pay attention to the thermometer. When the temperature of the thermometer is about to reach the required temperature, adjust the automatic temperature control knob so that the green indicator light is just on. After ten minutes, observe the thermometer and indicator light again. If the temperature indicated on the thermometer exceeds the required temperature while the red indicator light is still on, rotate the automatic temperature control knob slightly counterclockwise until the temperature remains constant at the required temperature. The indicator light will rotate in red and green until the desired temperature is reached. The automatic thermostat knob is located on the upper left side of the front of the box. Its scale plate cannot be used as a temperature standard indicator, it can only be used as a marker for adjustment.

(5) During the constant temperature process, if it is not necessary for three sets of heating wires to generate heat simultaneously, only one set of heating wires can be turned on. The more groups are activated, the faster the temperature rises.

(6) After working for a certain period of time, the top * air release regulator can be opened to expel moisture, or the blower can be turned on.

(7) After use, turn off all the electric heating wire grouping switches and turn the knob of the soil drying oven counterclockwise to the zero position.

(8) Unplug the power plug.
