Do you drink instant coffee or freshly ground coffee
Do you drink instant coffee or freshly ground coffee? Whichever you plan to produce, we both can offer automatic packing machine for drip coffee bag and instant coffee or freshly ground coffee.What is instant coffee
Instant coffee is different from freshly ground coffee, that is, hand-brewed coffee. After the cooked beans are ground and extracted, they are concentrated and dried under special pressure and temperature through industrial equipment to extract effective flavor substances and finally obtain instant coffee powder. .
In fact, the production of instant coffee is very complicated, much more complicated than getting a cup of freshly ground coffee. It can be said to be one of the important achievements of scientific and technological progress in the field of food industry in the 20th century.
How to choose instant coffee
Instant coffee can be divided into two types from the production process, one is spray-dried instant coffee, and the other is freeze-dried dehydration instant coffee. What is the difference between these two coffees, let's take a look.
Spray Drying Instant Coffee
This is a very common traditional craft and very efficient. To put it simply, this method is to put the coffee condensate into a high-temperature injector, and then spray it. The water in the sprayed coffee liquid will be evaporated, leaving behind small dry particles, that is, coffee The extracted crystals can be said to be the essence of coffee.
Freeze-dried dehydrated instant coffee
This kind of instant coffee will have more technical content. It uses the phase equilibrium theory of thermodynamics, which is the triple point of water. It should be known that when water is at a certain temperature and pressure, three states of gas, liquid and solid will coexist. scattered. Freeze-dried instant coffee is made using this principle.
Put the coffee concentrate in the state of the triple point, change the ambient pressure and supply heat, let the water in the solid coffee liquid sublimate and escape, and finally obtain granular freeze-dried coffee powder.
