VARIO Sample Dividers 

Variable sample dividers; TYPE 1G/1, 1G/2, 1G/4 and 1G/8

Purpose

Dividing samples of grain, seed and other granular products. Accurately dividing to the desired sample size in one operation. Copy sample option on some models.

Function description

The sample to be divided is poured through a hopper in the top of the divider. From the hopper the sample material glides through a rotating tube which passes a number of variable outlets leading the sample to sample tray. Sample material falling between the variable outlets, is guided out and away as surplus sample. The samples collected in the sample tray consists of a certain number of sub samples, the number of sub samples can be calculated by multiplying the number of rotations of the rotating tube (40 rpm) with the number of outlets. The accuracy of the dividing depends on the number of sub samples. To obtain the greatest accuracy, the time taken for dividing must never be less than 20 sec. With samples of less than 4 kg it is necessary to use an inlet hopper with a smaller outlet hole.

Example

Using a divider Vario 1G as shown on the principal drawing. 4 kg of sample should be reduced to 1 kg. The handle is moved to position 4 on the scale. The sample tray is placed in position. Check that the hopper is of the correct size. Start the divider by turning the switch on the front to position "drift". Pour the sample into the hopper and wait about 15 sec after the material has left the hopper. Stop the divider. The sample is now ready for analysis or storing.

Typical use:

The sample dividers are often used together with our process sampler DVB, which is used for taking samples from seed lots. Sample divider model 1G or 2H is used for this application. The sample divider is then started automatically when the DVB starts, and the sample drops into the hopper. Surplus sample material can automatically be transported back to process. In laboratories variable dividers can be used for very precise dividing of different materials. Compared with the "riffle type" divider and the "boerner divider" a lot of labour time is saved. In addition to this the required sample size can be obtained both easily and accurately. The divider can as an option be delivered with an electronic scale for precise adjustment.

Variable sample divider for floury products

Purpose

Dividing samples of grain, seed and other granular products. Accurately dividing to the desired sample size in one operation. Copy sample option on some models.

Function description

The sample to be divided is poured through a hopper in the top of the divider. From the hopper the sample material glides through a rotating tube which passes a number of variable outlets leading the sample to sample trays. Sample material falling between the variable outlets, is guided out and away as surplus sample.

The accuracy of the dividing depends on the number of sub samples. To obtain the greatest accuracy, the time taken for dividing must never be less than 20 sec. With samples of less than 4 kg it is necessary to use an inlet hopper with a smaller outlet hole.

Example

Using a divider Vario 1F as shown on the principal drawing (see Vario 2H). 4 kg of sample should be divided into a sample of 1 kg. The handle is moved to position 4 on the scale. The sample tray is placed in position. Check that the hopper is of the correct size, in this case no. 12. Start the divider by turning the switch on the front to position "drift". Pour the sample into the hopper and wait about 15 sec after the material has left the hopper. Stop the divider. The sample is now ready for analysis or storing.

With samples of less than 4 kg, it is necessary to use an inlet hopper with a smaller outlet hole.

Example

Using a divider Vario 2H as shown on the principal drawing. 4 kg of the sample should be divided into 2 samples of 1 kg each. I.e. one sample and one copy sample. The handle is moved to position 4 on the scale. The sample trays are placed in position. Check that the hopper is of the correct size, in this case no. 12. Start the divider by turning the switch on the front to position "drift". Pour the sample into the hopper and wait about 15 sec after the material has left the hopper. Stop the divider. Sample and copy sample are now ready for analysis or storing.

Typical use:

The sample dividers are often used together with our truck sampler RAKORAF, which is used for taking samples from all kinds of transport devices like trailers, lorries or wagons. Sample divider model 2H is used for this application. The sample divider is then started automatically when the reception box from the RAKORAF opens, and the sample drops into the hopper. Surplus sample material can automatically be transported out to a container. In laboratories, variable dividers can be used for very precise dividing of different materials. Compared with the "rifle type" divider and the "Boerner divider" a lot of labor time is saved. In addition to this, the required sample size can be obtained both easily and accurately. The divider can as an option be delivered with an electronic scale for precise adjustment.

Specification:

Surface treatment epoxy painted or electro galvanized. 
Motor 60 W, 230 V, 50 Hz.

Extension hopper 8 kg.
Sample tray in stainless. 2 or 3,5 liter.

Variable sample dividers, TYPE 4-8
PURPOSE:
Dividing samples of grain, seed and other granular products. Accurately dividing to the desired sample size in one operation. Copy sample option on some models.

Function description:

The sample to be divided is poured through a hopper (pos. 1.) in the top of the divider. From the hopper, the sample material glides through a rotating tube (pos. 2) which passes a number of variable outlets (pos. 11) leading the sample to sample trays (pos. 7 and 8). Sample material hitting between the variable outlets is guided out and away as a surplus sample (pos. 9). The samples collected in the sample trays (pos. 7 and 8) consists of a certain number of subsamples, the number of subsamples can be calculated by multiplying the number of rotations of the rotating tube (40 rpm) with the number of outlets. The accuracy of the dividing depends on the number of subsamples. To obtain the greatest accuracy, the time taken for dividing must never be less than 20 sec. With samples of less than 4 kg. it is necessary to use an inlet hopper with a smaller outlet hole.

Example:

Using a divider model 2 L as shown on the principal drawing. 4 kg of the sample should be divided into 2 samples of 1 kg. each. I.e. 1 sample and 1 copy sample. The handle (pos. 10) is moved to position 4 on the scale. The sample trays (pos. 7 and 8) are placed in position. Check that the hopper is of the correct size, in this case, no. 12. Start the divider by turning the switch on the front to position "drift". Pour the sample into the hopper and wait app. 15 sec after the material has left the hopper. Stop the divider. Sample and copy sample are now ready for analysis or storing.

Typical use:

The sample dividers are often used together with our sample taker type RAKORAF, this sample taker is used for taking samples from lorries. Sample dividers model 2H and 2L are used for this application. The sample divider is then started automatically when the reception box from the RAKORAF opens, and the sample drops into the hopper. Surplus sample material can automatically be transported out to a container. In laboratories, variable dividers can be used for very precise dividing of different materials. Compared with the "rifle type" divider and the "Boerner divider" a lot of labor time is saved. In addition to this, the required sample size can be obtained both easily and accurately. The divider can as an option be delivered with an electronic scale for precise adjustment.
