How to thoroughly clean the concentrator, the concentrator tells you

The vacuum concentration equipment in the concentrating equipment is one of the main equipment in the production process of the food factory. It uses vacuum evaporation or mechanical separation to achieve material concentration. At present, in order to improve the quality of concentrated products, vacuum concentration is widely used. Generally, in the low pressure state of 18~8KPa, the material liquid is heated by the indirect heating method to boil and evaporate at a low temperature, so that the material temperature is low and the heating is used. The temperature difference between the steam and the boiling liquid material increases, and under the same heat transfer condition, the evaporation rate is higher than that under normal pressure evaporation, which can reduce the loss of nutrient of the liquid material, and see the use of low pressure steam as the evaporation heat source.
In addition to the basic extraction tank, concentration tank, cooling condenser, liquid receiving tank and other components, the concentrator is equipped with a heating device, a stirring device, a jacket or a coil, a transmission device, a shaft sealing device, a heat insulating medium, and a feed. Feed port, support, temperature sensor, CIP interface, temperature control device, temperature measuring hole, CIP automatic rotating spray ball, defoamer, baffle, air distributor, temperature sensor, sight glass spotlight, liquid level gauge, etc. Equipment to facilitate manual operation.
For the concentrator supporting equipment, it must also comply with the national GMP sanitary standard. The material requirements for the supporting equipment must also be compatible with the main equipment, so as to avoid problems that do not match during the later operation and operation, affecting the equipment operation, and the production process. Significant impact.
Concentrator refers to equipment for concentrated production processes in Chinese medicine, health products, natural seasonings, food additives, food, chemical and other industries. Since the invention of the concentrator, it has been widely used in many fields such as chemical industry, pharmaceutical production and processing industry, ore processing industry, sewage treatment and so on.
How to clean the concentrator?
1. Cleaning of new equipment
After the concentrator is installed, add 1% caustic soda solution, heat and boil for 20-30 minutes, then drain the caustic soda and rinse it with clean water before concentrating the liquid. (Mainly cleaning oil and impurities in equipment processing).
2, change the variety cleaning
After heating the boiling cycle with a 1% caustic soda solution for 20-30 minutes, the inside of the cylinder is brushed with a round steel brush and washed with water. Open the separator of the evaporator and return the liquid pipe and other parts with hot water.
3, daily shutdown cleaning
After daily or after the end of each batch of production, add the appropriate amount of clear water to the extraction concentrator and heat it for about 20-30 minutes. Stop the sewage and wash it in clean water. After washing, add water to the mirror and wait until the next day or In the next operation, after draining the water in the equipment, the feed liquid can be operated.

RT-PCR For SARS-Cov-2 Testing

PCR ( Polymerase Chain Reaction)


It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.


Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.

Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.

SARS-Cov-2, One test type that uses a sample from a nose or throat swab in a 'PCR test'. The goal is to make enough copies of the viral cDNA in order for it to be detectable.
