Operation precautions of Snack Pellet Production Lines

As the production equipment of puffed snack food, the Snack Pellet Production Lines has the advantages of stable operation, simple operation, convenient use, safety and environmental protection, less investment, and fast income. It is favored by many small and medium-sized food processing enterprises.

Snack Pellet Production Lines

To better use the snack pellet production line and avoid unnecessary losses and injuries, we should pay attention to the following points in the operation:

Before power on:

(1).Check all parts, especially the connecting screws, anchor bolts, connecting bolts between the motor base and the frame, and the bolt connection between the expansion chamber and the frame, without looseness.

(2).Rotate the main shaft by hand. At this time, there shall be no rubbing sound in the expansion chamber.

(3).Start the feed auger, check its step-less speed regulation performance, and it is required to operate normally.

(4).Before start-up, check and clean the water circuit and steam circuit to ensure the normal supply of steam and water, and clean all filter systems.

(5).Before starting the machine, check whether the wiring of the electric control part is correct, whether the direction of each motor is correct, whether the control is reliable and effective, and ensure that the power supply and electrical equipment are normal.

(6).First, open the steam valve, preheat the expansion chamber, preheat at about 100 ℃ for the first time, and check whether there is water leakage or steam leakage.

During production:

(1).Parameters of temperature control instruments in each heating zone must be set according to process requirements. After the heating temperature of each section reaches the set value, continue to heat preservation, and further confirm whether the temperature control instrument and solenoid valve (or cooling fan) of each section work normally.

(2).The oil pump must be started before the motor.

(3).Idle speed shall not be too high without charging.

(4).Start feeding at the lowest possible speed and match the feeder’s speed with that of the main engine.

(5).Start the auxiliary feeding device according to the process requirements after the main machine and main feeding system are in normal operation.

(6).For exhaust operation, the vacuum pump shall be started after the main engine enters a stable operation state.

(7).Do not stand in front of the die before the strip comes out.

(8).Often check whether the extrusion strip of the head is stable and even whether there is any phenomenon such as broken strip, blocking of die hole, poor plasticization or overheating discoloration, and whether the head pressure indication is normal and stable.

(9).Every operation shall be recorded.

3. After shutdown:

(1).After shutdown, it is necessary to wear high-temperature gloves, quickly remove the discharge mold, clean up the materials. At the same time, they are hot and start the main motor to empty the materials accumulated in the expansion cavity.

(2).Take safety precautions when dismantling the machine. Do not stand in front of the nozzle to avoid danger from the residual pressure of the expansion chamber.

(3).After cleaning the machine, install the machine in reverse order.

(4).The transfer case and the electromagnetic speed regulating motor shall be maintained regularly. It is strictly prohibited to reverse the screw. It shall be operated in the direction of the signboard. Pay attention to the working environment to prevent dust from entering the magnetic pole (electromagnetic head), which causes solidification and out-of-control speed regulation.
