The baking range is adjusted in 4 seconds, 6 seconds and 8 seconds after the start of the second explosion. Of course, the finished product is mainly for the purpose of single product ESPERSSO. 2. HAPPYBOB: before I choose 2 explosions, it is probably between the last one and the first one, and the end of 40-

How many degrees does it take to climb? Smoke exhaust problem? What is the taxiing action? I would like to give you a little experience.

2015-09-15 Coffee roasting dehydration climbing smoke exhaust taxiing techniques recently quite a few brown friendsThe principle and process of coffee roasting we must first understand that raw beans are hard seeds in coffee berries, such as water, chlorogenic acid, protein, alkaloids, caffeine, fats, sugars and so on. While baking at high temperature, the above substances will undergo chemical changes such as Mena reaction and Stryker degradation, resulting in coffee tannic acid, nicotinic acid, aromatic esters, alcohols,

The better your coffee is made, the more intractable the ultimate problem of water temperature becomes. The water temperature seriously affects the quality of coffee, but it is difficult to control. The temperature of the water is not good, because the temperature of the boiling water in the espresso machine is higher than that of the machine.

2015-05-25 Brewing water temperature one cup coffee conditionThe quality of water temperature control absolutely affects whether a cup of coffee can preserve the delicious substances in the beans. The better your coffee is made, the more intractable the ultimate problem of water temperature becomes. The water temperature seriously affects the quality of coffee, but it is difficult to control. The water temperature is not easy to measure, because the temperature of the espresso machine is higher than 200 ℉, the amount of water is less, and the action of measurement is more or less.
2015-02-28 Brewing coffee water temperature elementsMany thermal and chemical reactions take place during baking: decarbonation, dehydration of quinic acid, fragmentation, isomerization, polymerization, and complex sugar reactions (caramelization). The main thermally reactive components are monosaccharides and sucrose, chlorogenic acid, displaced amino acids, and trigonelline amide. Both aravinone and calactose in polysaccharides are transferred, and basic sulfurization contains hydroxyamino acids.

Different baking appliances require different dehydration time, but it is usually best controlled at 5-8 minutes, depending on the water content of the beans. two。 Climbing temperature: usually the climbing temperature speed of baking is controlled between 7 and 14 degrees, which is related to the control of firepower, the better climbing temperature speed is controlled at about 10 degrees, and the water content of beans is different.

Exceeding this temperature will make some flavors particularly obvious, and if you don't reach this temperature, you won't be able to extract enough delicious ingredients. The effect of water temperature on taste the water temperature above 88C is too high, it is easy to produce air bubbles, resulting in incomplete steaming. 88C~84C (suitable for deep and moderate baking) has a strong taste and a bitter taste.

When the temperature of the coffee in the cup exceeds 60 degrees Celsius, the special fillers in these beans will melt, thus absorbing heat to lower the temperature of the coffee. On the other hand, when the coffee temperature in the cup is too low
