Adjustment and setting of the key machines and equipment for the success of Coffee Lacquer

Coffee-- Adjustment and setting of machines and equipment

1. Italian professional coffee maker

a. Boiler pressure

Boiler pressure gauge: the realistic unit of the boiler pressure gauge is bar, that is, the unit of atmospheric pressure, which is generally adjusted at 1 ±0.2bar. Some boiler pressure gauges and water pressure gauges are displayed in the same pressure gauge, which are configured for the upper and lower parts and left and right respectively. The easiest way to identify is that the measurement scale of the boiler pressure gauge is small, and the pointer does not change much when brewing coffee.

Boiler pressure adjustment box: most Italian coffee machine boiler pressure adjustment box is the same, only a small number of brands will use their own parts as adjustment, or use computer board settings, so, now we will introduce the general way. There are two adjusting screws on the boiler pressure adjustment box, one is the fixing screw and the other is the adjusting screw. When making the adjustment, you should first loosen the fixing screw, and then rotate the adjusting screw to adjust. Most of the adjustment directions are clockwise to reduce the pressure, counterclockwise to increase the pressure, and then tighten the fixing screw when adjusted to the set pressure value.

b. Cooking pressure

Brewing pressure gauge: the display unit of the brewing pressure gauge is also bar, which is generally adjusted to 9 ±2bar. When the brewing pressure gauge has not yet begun to brew coffee, the pressure displayed is the water pressure of the inlet pipe itself, usually about 1-2bar. After pressing the brewing switch, it will show the pressure of setting, and pay special attention to one thing: when you set the brewing pressure, you need to fill the brewing handle with coffee powder. This setting of cooking pressure is correct, because the pressure on coffee powder will be greater than when there is no coffee powder, so pay special attention to this.

Cooking pressure adjustment screw: the position of the cooking pressure screw is in the place of the water pump, and most of them need to remove some parts of the shell of the Italian coffee machine, but some Italian coffee machines are designed. The cooking pressure adjustment screw will be placed in an easy position. When adjusting the cooking pressure adjustment screw, it is necessary to loosen the screw line in the back section, and then rotate the front adjustment screw. And most of the adjustment directions are clockwise to reduce the pressure, counterclockwise to increase the pressure, and then tighten the fixing screw after adjusting to the set pressure value. however, there are still some Italian coffee machines where the cooking pressure adjustment screw rotates in the opposite direction.

two。 Commercial bean grinder

When the bean grinder adjusts the thickness of coffee powder, it only needs to rotate the turntable, and the direction of rotation adjustment scale is mostly clockwise, the thicker the coffee powder is, and the finer the coffee powder is when it rotates counterclockwise. On the other hand, the scale turntable of the commercial bean grinder is divided into two kinds: one is that there is a fixed clip on the scale turntable, and the adjustment of the scale is adjusted one by one, and the sales grid of the adjustment scale will vary according to the brand. Generally speaking, the smaller the adjustment, the better. Only in this way can we make more subtle adjustments. The other is that there is no fixed card bolt, so you can just turn the dial when adjusting, and you should also pay attention to grinding some coffee beans and withdrawing the coffee powder from the bean grinder trough after adjusting the dial turntable. Only in this way can the coffee beans grind out is the set thickness.
