A slicer is a machine for cutting thin and uniform tissue slices. Use hard paraffin or other materials to support the tissue, and push the thickness gauge to the required distance in the direction of the knife after each cut. The gradient of thickness gauge is generally 1 micron. When the paraffin embedded tissue is cut, because it adheres to the wax edge of the previous section, the slices are made into multiple slices.
Equipment for pelleting polymer strips. The slicer is composed of a strip guide plate, a feeding roller, a pressure roller and a rotary cutter head. The cutter head is driven by CVT, and the feed roller is driven by the cutter head through a set of change gears. According to the grain size, more blades are assembled on the cutter head. The cutting length can be changed by changing gears.
Adjusting the CVT can change the entry speed of the belt. Slicing is rectangular or cylindrical, most of the use of underwater granulator. The advantages of the method are that the melt or chip can avoid contacting oxygen in the air, the chip can be smooth, and the powder produced in granulation can be eliminated.
Pulp and paper industry: usually in the form of cutter head slicer, the heavy cutter head also acts as a flywheel to stabilize the slicing process.
The blade is radially installed along the disk surface and protrudes about 20 mm. The logs are fed through the chute to one side of the turntable. When slicing, the blade is at a certain angle with the log axis, and the processing capacity is 290m3 sub / h. generally, the rotating speed of the cutterhead is 249 rpm, the diameter of the cutterhead is 3360 mm, and the length of the wood chip is 24 mm. There are 16 blades installed on the cutterhead, which are carried out by four motors The total power is 4 × 315 kW and the motor speed is 25 rpm.
A machine for making sections of cells or tissues. Rotary and sliding microtome are used in optical microscope, ultrathin microtome is used in electron microscope, ultrathin microtome is made with glass knife or diamond knife.
Material devices include thermal expansion and mechanical propulsion. Frozen slicing method was used in frozen slicer, cryostat and ultra-thin frozen slicer. Cylinder slicer is used for freehand slicing.
