Application of sugar-coating machine:
This powder coating machine, also called tablet coating machine, spray coating machine is applied to make sugar-coated tablets after coating and polishing have a bright appearance, and the complete consolidation coating produced by the crystallization of sugar on the surface can not only prevent the chips from oxidative deterioration, moisture or volatilization but also cover the discomfort when taking the chips. The taste of the tablet is easy to identify and eases the dissolution in the human stomach and intestines. Sugarcoating machine is widely used in pharmaceutical, chemical, food, research institutes, and hospitals to sugar-coat, polish and roll food on tablets and pills, and can also be used for trial production of new drugs in scientific research units.

Working principle of powder coating machine:
In order to make the chips evenly coated with coating crystals on the surface as soon as possible and achieve the purpose of polishing, it is necessary to manually spray the chips in the pot with the syrup and mix the slurry. By rotating the pan clockwise, the sugar-coated tablets are tumbled in the pan, and the sliding friction grinding makes it evenly distributed on all the chips. At the same time, hot air is passed into the pot, which can quickly remove the moisture on the surface of the tablet, and finally obtain qualified sugar-coated tablets and other finished products. This series of machines is the best equipment for the sugar coating process. With the best pot body and stable line speed, the tablet can form the best logistics curve in the pot, so as to meet the process requirements of uniform thickness of the sugar-coating layer, bright color, and no pitting of powder coating machine, tablet coating machine, spray coating machine.
Structures:
⑴The movement of the tablet coating machine: This series of powder coating machines is a one-way, low-speed continuous rotation coating equipment. The main motor drives the pot body to rotate through the belt drive—the worm and worm gear drive.
(2) Structural characteristics of spray coating machine:
An a. There is an adjustment handwheel in the middle of the machine, which can be used by the unit to adjust the inclination angle of the sugar-coating pan according to the tablet loading and material exchange performance. (The charge amount on the nameplate of this machine is based on the inclination angle of the pot body of 30o.)
B. The worm gear and worm are used as the terminal output of the movement, which has the characteristics of stable operation and self-locking of the pot body.
C. The hot air drying device adopts resistance wire heating and separates high and low-temperature switches for easy control.
Machine installation of coating machine:
1. Turn on the power. Note: The phase line and the neutral line cannot be wrongly connected.
2. Connect the air source to the trachea connector on the underside of the body through the Φ8PU tube.
3. Add the coating liquid to the liquid cylinder.
4. Turn on the power switch and turn on the power at this time.
5. Adjust the speed of the main engine according to the instructions of the main engine governor.
6. Turn on the air intake adjustment switch, and the air intake fan starts to work.
7. Adjust the temperature controller to adjust the temperature to the temperature you need. At this time, if the actual temperature is lower than the set value, the heater is powered on and the heater starts to heat. If the actual temperature is higher than the set value, the heater power is cut off and the heater stops heating.
8. Turn on the spray gun switch, and the spray gun starts to work, please refer to the spray gun manual for the use of the spray gun.
9. After the above functions are properly adjusted, the air compressor can be turned on, and the air pressure is about 4-6kg/cm3 of the spray coating machine.
Lubricating of coating machine:
The bearings, worm gear, and worm in the reduction box are lubricated by splash type, and the uppermost bearing is lubricated by an oil cup, and the oil cup should be refueled regularly. The gearbox oil should be changed every six months, using HL20 in winter and HL30 gear oil in summer.
installment and debugging of powder coating machine:
1. After the tablet coating machine is in place, it must be placed stably and fixed with anchor bolts.
2. Open the oil filling cover and add lubricating oil to the gearbox to the oil mark line.
3. Place the electrical control box on the dry and easy-to-operate side. After the power is turned on, pay attention to its consistency and make the sugar-coated pan rotate clockwise.
4. During the test drive, pay attention to whether the machine has abnormal noise, so as to stop and check-in time.
5. The inclination of the sugar-coated pan is related to the filling capacity and the exchange performance of objects. Generally, when the filling amount is moderate and the inclination angle of the sugar-coated pan is 30o, the production efficiency and quality are good.
