Parameters of coffee machines.
Automatic
grain coffee machines equipped with a built-in coffee grinder. Espresso is prepared with one press: the coffee is ground and sent from the coffee grinder to the brewing mechanism, where the coffee is pressed, and hot water is fed through it under pressure, after which the finished drink enters the cup.
Professional coffee machines are usually called big cone machines. The process of making espresso in them is as follows: freshly ground coffee is placed in the horn-holder (this is a removable part of the coffee machine), then the coffee is tamped manually, and the horn is fixed in the coffee machine. The button is pressed, water under pressure passes through the horn and pours into the cup already in the form of espresso. For such coffee machines, you need to additionally purchase separate coffee grinders.
Automatic coffee machines use ground coffee, which is poured into a tank (for 250-1000 g) and then enters the built-in coffee grinder. Some models of coffee machines have a function of using ground coffee. In this case, ground coffee (7-9 grams) is poured with a measuring spoon directly into the brewing mechanism and a portion of espresso is prepared.
Coffee beans are used to prepare coffee on professional coffee machines, but they are ground on an external autonomous coffee grinder.
Find out how to choose coffee for a coffee machine
Water capacity, l
Most automatic coffee machines are equipped with a water tank with a capacity of, as a rule, 1.5-2.5 liters. This volume is usually enough for 5-10 cups of coffee. With a load of more than 30 cups of coffee per day, it is reasonable to think about a model with a capacity of more than 3 liters.
Some office coffee machines can be connected to a 19 liter bottle or a 10 to 20 liter canister. You can completely close the issue of water supply by connecting the coffee machine to the water supply.
Professional coffee machines in 98% of cases initially assume connection to the central water supply.
Connection to water tanks: bottle 19 l, canister 10 l, tank 20 l.
Water can be supplied to the coffee machine from additional containers through a silicone hose. Bottle 19 l. or a 20 l tank. placed either under a table with a coffee machine or in a special cabinet. Canister 10 l. it can be placed both on the tabletop behind the coffee machine and on the floor under the coffee machine.
Capacity for coffee beans, gr
The coffee tank of automatic coffee machines usually holds 150 to 350 grams of beans, which is enough to prepare 20-50 portions of coffee. When consuming more than 50 cups of coffee per day, it is rational to consider coffee machines with larger containers.
Some coffee machines can be equipped with an expander that increases the capacity of the bean coffee tank to 900 grams.
The volume of the container for spent coffee, portions
In the conditions of a small office or home, it is enough that the container for spent coffee can hold 8-10 servings. For medium-sized offices with a consumption of 30-50 cups per day, it is better to consider coffee machines with a tank for processing 25-30 servings. In offices with daily consumption of more than 50 cups of coffee, containers for 40-70 portions are optimal.
Volume of the waste water tray, l
(//tractor-service.com)
The tray for used water (drip collector) should be large enough for loads of more than 30 cups of coffee per day. On all automatic coffee machines, about 15-20 ml of water is poured into the tray after each prepared cup of coffee. That is, a small drip tray with a volume of 500 ml is filled after making 20-30 portions of coffee.
It should be borne in mind that most drip trays have a flat shape, and it is inconvenient to carry them far to drain the water. On professional coffee machines,
draining used water is carried out, as a rule, directly into the sewer.
Connection to the water supply
Components for connecting the coffee machine to the water supply can either be included in the factory or purchased additionally. Filters for water purification are not included in the set.
Adjustment of the cup filling volume
On automatic coffee machines, the cup filling volume is either programmed for several types of cups, or selected before preparation using a mechanical regulator (for example, from 20 to 250 ml). On professional horn coffee machines, the volume is either programmed to different buttons, or the pouring stop is carried out manually. The first type of professional machines is classified as automatic, the second - as semi-automatic.
Dosage of coffee beans
On GAGGIA and SAECO automatic coffee machines, the amount of beans per serving is adjustable in the range from 6 to 9 grams. The optimal dosage is 8-8.5 gr. Depending on the coffee machine model, the selection of the number of beans per portion is carried out either by a mechanical regulator or through the menu (on coffee machines with a display). The selection of beans for professional corn coffee machines is made on a coffee grinder. Holders of different volumes are used for different drinks - from 7 to 22 grams - respectively for single or double espresso.
The maximum height of the cups
The parameter shows how tall cups, glasses, and mugs can be placed freely, without tilting, to pour coffee under the dispenser. On many coffee machines, for example, the GAGGIA Logic and SAECO Aulika series, the dispenser is adjustable in two planes: vertically and horizontally, in the second case, the dispenser moves inside the coffee machine, which allows you to use glasses of maximum height.
Preparation of cappuccino
Cappuccino can be prepared in the following ways:
1. Not automatically. Milk is whipped by steam in a cup or pitcher, then the whipped milk is added to coffee, or vice versa.*
2. Semi-automatic. Milk is whipped by an automatic cappuccino machine, but after obtaining milk foam, the cup must be moved under the coffee dispensing spout.
3. One click. You just press the button, and the coffee machine will do everything by itself - prepare milk foam and add espresso to it. Coffee machines of this type are also called super machines.
Buy an automatic cappuccino maker that allows you to prepare cappuccino in a semi-automatic mode.
Cappuccinator
A manual cappuccino maker is a metal tube from which steam is supplied. Milk is whipped in a cup or pitcher.
The automatic cappuccino maker provides fully automatic preparation of milk foam. There are two main types of automatic cappuccino machines: in the form of a container into which milk is poured and then whipped, or in the form of a compact nozzle, into which milk enters through a silicone tube, and after whipping, milk foam is poured into the cup. The first type is suitable only for the home, as it requires more time for cleaning. The second type is universal and can be used both in everyday life and in professional or office applications. For many coffee machines, it is possible to purchase and install an auto-cappuccinator nozzle instead of a manual version.
