â— The liquid circulation of the whole system is closed. The system has an expansion vessel. The expansion vessel and the liquid circulation are insulated. They do not participate in the liquid circulation. They are only mechanical connections, regardless of whether the temperature of the liquid circulation is high temperature or medium in the low temperature expansion vessel. Below 60 degrees. â— The whole liquid circulation is a closed system. There is no water vapor absorption at low temperature. There is no oil mist at high temperature. The heat transfer oil can have a wide working temperature. The same machine can achieve -100 degrees to 200 degrees with the same heat transfer medium. Temperature control. Cooling capacity 1KW ~ 80KW range â— No mechanical and electronic valves are used throughout the circulatory system. The main disadvantages of traditional collusion slotted temperature control devices are: 1. The oil bath has a large volume of oil bath. There are two main functions: When the slotted system controls the outer loop, such as the jacket reaction, the larger the volume of the reactor, the larger the volume of the jacket. The more heat transfer medium of the whole system, the greater the concentration change during heating and cooling, oil bath, water bath The larger the volume requirement. 2, water vapor absorption When the low temperature reaction, the surface temperature of the slotted oil bath is very low, it is easy to absorb the water vapor in the air on the evaporator surface of the compressor, ice is a good insulator, the evaporator of the compressor It is insulated and cannot conduct heat, so the compressor cannot cool the heat transfer medium and cannot reduce the temperature inside the kettle. 3. When the oil mist reacts at high temperature, the heat transfer oil will volatilize into the air of the laboratory and condense on the surface of the furniture, blocking the filter of the fume hood. Because of the different flash point of the heat transfer oil, some can cause combustion and explosion, and the heat transfer oil It can only be used 5 degrees below the flash point, so the temperature range of the heat transfer oil is limited, so a medium is needed at high temperature, another medium needs to be replaced at low temperature, and the heat transfer oil is easily browned and oxidized at high temperature. Therefore, it is necessary to replace the heat transfer oil regularly, and the use cost is relatively high. The fast temperature rise and temperature system products achieve precise temperature control of the reaction: the characteristics are as follows 4, with self-diagnosis function, freezer overload protection, high-pressure pressure switch, overload relay, thermal protection device and other security functions, fully guarantee the safety of use; The adaptive control system continuously adjusts the PID parameters during the control process (such as the chemical reaction process) to give the process a good control temperature and response time. This process is effective in multi-directional measurement of temperature, temperature change and The rate of temperature change is achieved. 6. Function with PT100 for correcting external circulation and internal circulation temperature probe. 7. Use CFC-free and HCFE refrigerants. 8. Precise control of the speed of the chemical reaction.
Anthocyanidins is a kind of water-soluble natural pigments widely existing in plants in nature. They are colored aglycone obtained from the hydrolysis of anthocyanins. Most of the main colorants in fruits, vegetables and flowers are related to them. Under the condition of different PH value of plant cell vacuoles, anthocyanidins make the petals colorful. The main functions about anthocyanidins are antioxidant and free radical scavenging function, nutritional fortifier in food and natural pigment.

A. Holding the heat transfer medium B. The heat transfer medium has the physical properties of thermal expansion and contraction, and the tank body is equivalent to the expansion container.
The heat load during the temperature change of the whole system is the total heat transfer oil of the whole system (mainly) + the reactants in the reactor body. The larger the volume of the water bath and the oil bath, the smaller the effective power for the kettle body, and the reactants in the kettle body. The slower the speed response and rate of warming and cooling.
The temperature control of the reactor is controlled by the temperature change of the heat transfer oil of the reactor jacket. The more heat transfer medium of the system, the less the effective power is used in the kettle body, and the slower the temperature control.
4. Heating and cooling need manual switching, which is prone to misoperation and accidents.
1. Equipped with heating and cooling integrated container, the heat exchange area is large, the rate of heating and cooling is very fast, and the demand for heat transfer oil is relatively small.
2, can achieve continuous lifting temperature, using high temperature and high pressure running compressor technology, can directly open the compressor refrigeration from 200 degrees, improve energy efficiency.
3, the whole cycle is closed, no oil mist volatilization at high temperature, the heat transfer oil will not be oxidized and browned; at low temperature will not absorb the water vapor in the air; prolong the life of the heat transfer oil.
5, temperature adaptive control
