(3) After the assembly, ground wire in 0.5-1m depth shall be made 3-5 m away from
the machine prior to operation.
4. Operation and use:
(1) Before use, it is necessary to carefully read the operating manual instruction and
be familiar with the performance emphasis and operating methods;
(2) Before starting-up, a complete inspection on the machine shall be made to make
sure that there are no loosened fasteners and inflexible handles. When turning around
the belt pulley with hand, all running parts shall be in good condition without any
abnormal noises. Then fill up the reduction gear box with # 20 machine oil;
(3) Loosen the locking nuts; turn around the stretching screw anticlockwise to make
the conical surfaces of squeezing bolt and cake outlet closely contact, then screw out
the stretching screw 2-3mm clockwise. After screwing up the nuts, prepare to start up
machine.
(4) Open the door of electric appliance and open the air break switch of power in the
case (placed in a suitable location) to switch on the power of complete machine;
(5) Adjust the temperature controller to 120-200
℃
for pressing (depends on different
kind of oilseeds). Turn the master heating switch to heat the machine. When the
temperature of the machine reaches the fixed value, the light on the temperature
controller will change from green light on and red light off to red on and green off.
The temperature set up for the machine is 120-200
℃
. In winter, please switch on the
oil pan to increase the temperature for oil flowing down;
(6) Press the positive rotation button of main engine; it will start to run at
anticlockwise direction.
(7) The new assembled machine shall have 2-8 hours pressing. Slowly put the used
cake material
（
rapeseed cake, soybean cake, cotton seed cake or cotton shell and
paddy shell
）
into the hopper and repeated for times to polish the pressing chamber and
easily making out cakes. Do not put the oilseeds directly into the hopper when starting
to press;
(8) The material shall be slowly put into the hopper. The machine shall be
immediately shut down to clear up the hamper when abnormal noises happen or the
squeezing bolt axis was locked because of heavy feeding. The machine can be
restarted up after assemble. Forcefully pulling machine or reversal pouring materials
are strictly forbidden. During normal pressing, regular pattern shall be achieved.
Control the cake thickness between 0.5-2mm and there is no residue in low pressure
section but few residues in high pressure section with the proportion of residue
against oil not higher than 10%. The temperature of pressing chamber can reach
120-200
℃
, so the blue smoke shall be piped out by piping line from hood shield and
the hot cake shall be timely spread out to avoid spontaneous combustion. When the
temperature of the machine is too high because of long time working, electric fan
shall be used to cool down;
