In the bio-pharmaceutical, food, daily chemical, new materials and other industries, research and development is the driving force for these industries to maintain their core competitiveness. In the research and development of these industries, small high-shear emulsifiers are commonly used in the laboratory for mixing and heating. device. Through the synergistic effect of the powerful centrifugal extrusion, shearing and other mechanical forces of the laboratory vacuum emulsifier and the mature process formula, the experimental materials can be uniformly mixed, dispersed, homogenized and emulsified to achieve a satisfactory finished product effect.
In the use of high shear emulsifiers in the laboratory, what are the safety precautions for use? Let's take a look:
1. Laboratory high-shear emulsifier generally adopts high-speed homogenizing shear head, which adopts high-speed motor, and the rotation speed is generally high. For example, the speed of the sixth-generation new laboratory high-shear emulsifier of Yikai is Up to 6000 rpm, this high-speed working head should not be turned on in the state of the empty pot in the pot body, so as to avoid the degree of sealing of the mechanical seal due to local heating.
2. In terms of electricity consumption, the ground wire is reliably grounded to ensure safe use of electricity.
3. The shaft end of the homogenizer is seen as a right turn. The test run should be jogged after each motor wiring or when it is not re-enabled for a long time. When the confirmation is correct, the homogenizer is officially operated.
4 Each time before the start of stirring, it should be jogged to check whether there is any abnormality in the stirring scraping wall. If it is necessary, it should be removed immediately.
5 Before using the vacuuming function, be sure to check whether the pot and the lid are flat, whether the pot and the mouth 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.
7 The vacuum pump can be started up under the 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 while the equipment is running 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 the precautions for the use of laboratory emulsifier. The service life of the equipment is not only related to the quality of the equipment, but also closely related to the use and maintenance of the equipment. In order to ensure the normal operation of the experiment and the long service life of the equipment, please be strict. Observe the safety guidelines of the emulsifier manufacturer and maintain the emulsifier equipment.
Freeze-drying powder process includes: fresh fruit selection - cleaning - cutting - blanching - cooling - drying - grinding beating - gel grinding - sterilization - pre-freezing - vacuum freeze-drying - ultra-fine grinding - weighing packaging - testing - finished product.
Firstly, fresh and mature fruits with good quality were selected in the pre-treatment area of the food lyophilizer, and the leaves were removed to remove impurities. Then, preliminary cleaning and simultaneous sterilization of fruit surface were carried out. After sterilization, the fruits were cleaned and drained again. After the drain, the fruit is sliced and treated by blanching process. After the color preservation, the fruit is treated by pulping, and then pasteurized. The pretreatment process is finished before lyophilization.
The processing core of freeze-drying powder is the equipment area of food freeze-drying machine. After pre-treatment, the fruit enters the equipment of food freeze-drying machine and crystallizes into a solid state at low temperature, and then sublimates and dries in a vacuum environment to obtain freeze-drying products with little water content. Freeze-dried products out of the warehouse into the food freeze-dried post-processing area, ultrafine grinding, and then according to the need to do weighing packaging, after testing the finished products packed into storage.
