Tensile testing machine for wooden boards with a cross-section of max. 50 x 260 mm, max. tensile strength 450 kN
Description
The chocolate is heated in special, heated mixing unit for between twelve and 24 hours at temperatures up to 90°C, while high quality chocolate can be conched for up to 72 hours. During this process, the cocoa butter repeatedly flows out of the openings, and deposits itself evenly on the chocolate particles. The result is a sifter, liquid coating. Water is removed from the chocolate mass through the heat and the oxygen, and the final moisture content of the chocolate amounts to only approximately one percent. Other residual and undesirable off-flavored and bitter substances (acetaldehyde, acetone, i-butyl alcohol, ethanol, i-propyl alcohol, ethyl acetate, acetic acid, i-pentanal, methanol, diacetyl). If necessary, more cocoa is added to chocolate mass at the end of the conching process.
Design
The machine consists of the following modules:
Clamping and traction unit, comprising:
- Main support for mechanism
- Base plates for supporting clamping plates
- Clamping plates with special toothing, unhardened, replaceable
- Two guide shafts, hardened and polished
- Two hydraulic hollow cylinders for generating tensile force
- Two hydraulic clamping cylinders for generating clamping force
- Hydraulic fittings for connecting to the hydraulic unit
Clamping unit, comprising:

Safety devices
conforming to SUVA and CE
- Machine operation
- The machine is operated from a control panel.
- Clamping pressure freely selectable.
- Tensile force freely selectable.
The test can be carried out to a pre-set tensile force or until rupture. The values are shown on the display. A PC can be connected and data recorded (optional).
