Fast delivery for TU-1H01 thermal wax actuator for industrial thermostatic water regulations mixing valve for Mali Manufacturers Detail:
1. Operation Principle
The Thermostatic Wax that has been sealed in shell body induces expansion by a given temperature, and inner rubber seal part drives its handspike to move under expansion pressure to realize a transition from thermal energy into mechanical energy. The Thermostatic Wax brings an upward movement to its handspike, and automatic control of various function are realized by use of upward movement of handspike. The return of handspike is accomplished by negative load in a given returned temperature.
2. Characteristic
(1)Small body size, occupied limited space, and its size and structure may be designed in according to the location where needs to work.
(2)Temperature control is reliable and nicety
(3)No shaking and tranquilization in working condition.
(4)The element doesn’t need special maintenance.
(5)Working life is long.
3.Main Technical Parameters
(1)Handspike’s height may be confirmed by drawing and technical parameters
(2)Handspike movement is relatives to the temperature range of the element, and the effective distance range is from 1.5mm to 20 mm.
(3)Temperature control range of thermal wax actuator is between –20 ~ 230℃.
(4)Lag phenomenon is generally 1 ~ 2℃. Friction of each component part and lag of the component part temperature cause a lag phenomenon. Because there is a difference between up and down curve of traveling distance.
(5)Loading force of thermal wax actuator is difference, it depends on its’ shell size.

The coffee is a popular drink. The modern life can be fast and complicated. People drink more coffee, if life is more complicated. The coffee roasting is the transformation of the chemical and physical properties of green coffee beans into the roasted coffee products. The roasting process can produce a very tasty coffee. When roasted, the green coffee bean increases its size. The bean changes color and density. The color changes to yellow, then to a light brown color, and finally to the dark color of chocolate. During the roasting, oil can appear on the surface of the coffee beans. The coffee roasting can continue until the coffee beans are removed from the machine.
In Argentina, Costa Rica, Bolivia, Mexico, Spain, France, Italy, and Portugal, beautiful women add 15% sugar to the coffee beans. The sugar changes into caramel, and sticks to the coffee beans. The final coffee does have the flavor of candy. The addition of sugar to the process causes the product to lose quality, but it changes the taste. Some people like it.
Coffee beans from famous regions of Indonesia, Kenya, Hawaii and Jamaica are usually roasted on soft heat for best flavor. In the past, the coffee was purchased as green beans and was roasted in a pan. This form of roasting requires great skill. During the roasting, the coffee emits CO2 for several days after roasting. It is better to wait a few days before closing the roasted coffee in vacuum.
Today, the roasting of coffee beans at home is becoming popular again. There are automated machines for coffee roasting at home. Some nice women use popcorn machines for roasting coffee. Once the green coffee is roasted, the coffee loses its flavor in a week. The roasted coffee can become more sour and bitter, when it is old. It is important to remove CO2 from the roasted coffee.
The roasted coffee is obtained after the special roasting process. Different roasting time can produce different flavors of coffee. The coffee roasting process consists of the cleaning, roasting, cooling, grinding and packaging. The green coffee beans are cleaned. The green beans are weighed and transferred to the storage container. From the storage, the green beans are slowly moved to the roasting machine. The machines for coffee roasting do heat-up the coffee beans between 190 and 280 ° C. The green beans are roasted over a period of 3 minutes to 30 minutes. The coffee roasting machine helps the coffee beans to move and to be protected from too much heat.
The coffee beans are obtained from the seeds of the fruit of the coffee plant. The dark coffee is good for stimulation of hormones and blood pressure, because it contains caffeine. Green mate tea can have a stronger effect than coffee, but the taste is different. People can become addicted to coffee, because it can regulate the hormones in some people.
The coffee roasting machine is a wonderful machine. It can convert green coffee beans into fresh coffee that shops and restaurants can sell to the happy customers. epSos.de is happy about this machine. The typical temperature of the machine for coffee roasting is between 60 and 220 ° C. Good machines can change the temperature during the roasting process. The coffee beans need to move well, because the heat is not in all parts of the machine. After the roasting process, the coffee must be cooled quickly, if you want to have the best flavor.
