What are the details to be aware of when using a homogeneous vacuum emulsifier?

The homogeneous vacuum emulsifier is a complete system integrating mixing, dispersing, homogenizing, emulsifying and absorbing powder. It has an electronic control system and can also be used with peripheral oil, water phase tank, vacuum, heating/cooling system, etc. . It is a special equipment for producing medicinal ointments, high-grade creams, lotions, etc.

The working principle is as follows: the material is stirred through the center of the upper part of the emulsification pot, and the PTFE scraper always greets the stirring pot body, sweeping the wall-mounted adhesive material, so that the scraped material continuously generates a new interface, and then passes through the blade and the slewing. The blade is sheared, compressed, folded, and stirred and mixed to flow down to the homogenizer below the pot body. The material is then sheared, impacted, and sheared by a high-speed rotating cutting wheel and a fixed cutting sleeve. In the process of turbulent flow, the material is cut in the shear joint and rapidly broken into particles of 200nm-2um. Since the emulsion tank is in a vacuum state, the bubbles generated during the stirring process are taken away in time. By vacuuming, the produced products are no longer mixed with air bubbles during the stirring process, thereby ensuring the production of high-quality products with luster, fineness and good ductility.

The components are composed of main pot, oil pan, water pot, electrical control system, hydraulic system, vacuum system and rack. The main pot consists of a homogeneous stirring pot, a homogenizing mechanism, a two-way stirring mechanism, etc. The following is mainly about how to operate and pay attention to the vacuum homogenizing emulsifier.

The first is the operation steps and methods of the device.

1. Turn on the vacuum homogenizing emulsifier power supply, the power supply is consistent, and pay attention to the grounding of the grounding wire. Turn on the main power switch, turn on the controller power, and the indicator light is on.

2. Connect the pipes of the homogenizer correctly (including the overflow, drain and drain).

3. Before vacuuming work, be sure to check whether the emulsifier pot is flat with the lid, and whether the pot mouth and the material port cover are tightly sealed and the seal is reliable. Close the valve ports on the lid, then open the vacuum valve on the lid, then open the vacuum pump to vacuum, close the vacuum pump when the requirements are met, and close the vacuum valve. (See the operation process flow chart for details)

4. Homogeneous cutting and scraper mixing: After feeding (when commissioning, water can be used instead), the corresponding control switch is opened to control the operation of the homogenizer and the stirring of the scraper. Before the start of stirring, it should also be jogged to check if there is any abnormality in the stirring scraping wall. If it is necessary, it should be removed immediately.

5. The vacuum pump can start running under the sealed condition of the homogenizer. If there is a special need to open the atmosphere to start the pump, the operation can not be more than 3 minutes.

6. The vacuum pump is strictly prohibited to run without working fluid. Do not block the exhaust port while the pump is running.

7. Regularly check the lubricating oil and grease in each component and bearing, and replace the clean lubricating oil and grease in time.

8. Keep the homogenizer clean. Every time you want to stop using or replacing materials, you should clean the contact part of the homogenizer with the working fluid, especially the cutting wheel cutting sleeve of the head, the sliding bearing and the bushing in the homogeneous bushing. After the cleaning and reassembly, the hand-turning impeller should have no stuck phenomenon. After the two flanges of the pot body and the lid are fixed, the motor of the homogenizer is turned correctly, and no other abnormalities can be started.

9. The cleaning work of all emulsification pots is handled by the user according to the standard.

Precautions

1. Since the homogenizing cutting head is extremely high, it must not be operated in the empty pan state to avoid the degree of sealing after local heating.

2. The ground wire is reliably grounded to ensure safe use of electricity.

3. The homogenizer is reversed from the top to the bottom. When the motor is connected or does not need to be restarted for a long time, it should be jogged. The mixing frame is turned from top to bottom as a reversal, and the stirring blade is seen from the top to the bottom. turn. When commissioning, you should first jog the test run, and then let the homogenizer run when it is correct.

4, each time before the start of the stirring should be jogged, check whether the stirring scraping wall is abnormal, if it should be removed immediately.

5. Before stirring and vacuuming, be sure to check whether the pot is flat with the lid, whether the pot mouth and the material port cover are tightly sealed, and the seal is reliable.

6. Before the vacuum pump is turned off, the ball valve in front of the vacuum pump should be closed first.

7. The vacuum pump can start running under the sealed condition of the homogenizer. If there is a special need to open the atmosphere to start the pump, the operation can not exceed 3 minutes.

8. The equipment must be disconnected from the power supply before any maintenance or cleaning.

9. Never put your hand into the kettle during the operation of the equipment to prevent accidents.

10. If there is any difference, the operation will stop immediately after the operation, and the machine can be started after the cause is found.

The above is all shared today. Through the sharing of the above series, what are the details that need to be paid attention to when using a homogeneous vacuum emulsifier ? Have you learned it? I also hope that this article can help everyone.
