Built in air source soil incubatorAdopting a dual mode of drying oven module heating and hot air,Simulate indoor air flow mode, namely air drying mode for soil drying. The air is clean and 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.mainDrying of soil, sediment, and solid waste samples for heavy metal element analysis.

1) Air drying, purification, and heating unit: composed of an air purifier and a constant temperature heater, the air is processed by this unit to become a dry and clean air source, which is input into 24 sample rooms for heating.

2) Sample RoomThere are 24 independent sample chambers on the host, with temperature display and no interference with each other. All 24 sample rooms are made of 304 stainless steel material, and the cabin doors are equipped with observation windows for easy observation of the drying status of the samples.

3) Gas path: Connected from a main air inlet to a 4-way gas heating distributor, forming 4 channels, and then passing through 4 6-way gas distributors to form a 24 way gas pathEnter 24 sample chambers, each with one gas source inlet.

2、 Main features of the instrument:

1) Digital displaySoil drying ovenComposed of a digital constant temperature module, air purification, heating unit, sample chamber, and gas circuit.

2) Inside the box is an independent 24 position sample chamber,Use in any quantity,Separate the samples to prevent cross contamination.

3) The soil drying oven adopts air disturbance technology to simulate indoor air flow, approaching the room

Internal environment to achieve rapid air drying. the machineThe dryer used allows the sample to enter the chamber

The air is first dried to remove moisture, and then purified and adsorbed by a filter layer to produce clean air

Air, to prevent secondary contamination of the sample due to unclean dry air.

Using heated dry air technology,The constant temperature range is 35 ℃, with an error of ≤± 5 ℃,The heating temperature is 60 ℃.Improved sample drying efficiency and flexibility in use.

5) The stainless steel design of the gas processing room facilitates observation of the usage status of desiccants.

6) Gas insulation transmission to avoid the influence of external temperature. Silencing treatment of the air source box to reduce noise.

7）Each sample room is equipped with one air inlet, and the tray is directly inside the sample room to ensure uniform and rapid drying of the samples.

8) The sample room is made of stainless steel material, which avoids chemical corrosion and organic matter adsorption, and is easy to clean and maintain;

9) The sample room can be equipped with trays, which can directly place ordinary soil samples or high moisture samples such as river sediment. The bottom is equipped with rollers for easy movement.

10) The volume of the sample compartment is long×wide×High is 300*200120mm， The tray can withstand up to 1kg of soil sample.

11）The bottom is equipped with rollers for easy movement,Easy to operate and maintain.

threeWorking principle and introduction of each unit:

Air constant flow pump gas outlet→ Airpurifier→Gas distributor→ 24 sample roomsAir with a certain pressure from an air constant flow pump is dried by a dryer to remove moisture from the air, and then purified by a purifier to remove particulate matter and chemicals from the air, resulting in dryness、Clean air is then transported to 24 sample rooms through a gas distributorHeat and air dry the soil sample at the same time.

3.1 Drying machineintroductionThe dryer consists of a quick connector, end cap, sealing ring, housing, and stainless steel mesh

Composition, with desiccant inside. Air is dried by a dryer to remove moisture (H2O) and produce dry air.

3.2 PurifierintroductionThe purifier consists of a stainless steel mesh, a spray cotton filter layer, and a housing. After drying

The air that has been dried enters the purifier,Further remove>10u of various dust and particulate matter through a spray cotton filter layer,

Generate clean air.

Note: The purifier can be replaced once a year, either by yourself or by contacting the manufacturer to replace it with the original onepurifier.
