The OTTAWA Food Extrusion Test Device (OTMS) consists of a square test cell with solid walls and an open base which can be adjusted with one of the wide variety of dishes which are included in the kit. The test method involves weighing a quantity of sample which is placed in the cell with any grated or perforated plate. In any case, the result is determined by measuring the resultant force required to squeeze the sample.
The device can be adapted to different material specimens by means of different extrusion plates and jaws for volume reduction. The compression forces can be measured with the use of the sealing plate.
The OTTAWA Food Extrusion System will produce a graph similar to that of the Kramer Test Cell.
• The sample is compressed
• The sample extrudes the liquid part
• The sample is extruded through the base
The strength level of the sample and the amount of work required to extrude the sample will obviously vary between product types and it is important to use the same base cavity to compare the results between different products.
This probe is mainly used for the compression of foods composed of units of variable size and that could have a very high variation if they were compressed individually, This test device can be used to obtain useful data for food products where an extrusion process is used during its manufacture. Ideal for testing beans, cereals, fruit fillings, soft vegetables, peas, canned fruits and snack products.
