3. Technical characteristics
3.1 General characteristics of the different models
The La San Marco grinders-dispensers are professional equipment designed for grinding and metering cof-
fee beans. La San Marco S.p.A. manufactures two basic grinder-dispenser models: SM 90; SM 95. They are
essentially made up of:
• A painted aluminium housing
1
. The size, shape and volume are identical for all models.
• A hopper
3
, made of transparent plastic material, positioned on top of the grinder-dispenser. The hopper
is fixed to the grinder-dispenser by a special screw. The hopper can only be removed with the help of an
appropriate tool. Inside the hopper there is a guard
6
that prevents the accidental contact of the hands
with the grinders.
• An electric motor to which the grinding unit is connected.
• A grinding unit. Model SM 90 and model SM 95 are equipped with a grinding unit with flat grinders of 64
mm and 84 mm diameter, respectively.
• A grind adjustment ring
7
with a release button
8
. The top of the ring shows the grinding adjustments pos-
sible. The ring is turned clockwise or counterclockwise to change the fineness of the ground coffee.
• A dispenser
9
designed to measure and dispense the ground coffee; it has an adjustment range from 5
to 9 grams or, in the increased dose configuration, from 6 to 10 grams. The amount of ground coffee dis-
pensed can be adjusted by operating on the control knob
11
, located inside the dispenser. The ground
coffee is dispensed by pulling on the coffee dispensing lever
13
. The presser
12
, available on cylindrical
and conical versions, enables the ground coffee to be pressed down inside the filter cup.
• A support fork
14
for the filter cup.
• (SM 90/95 automatic version only). An electronic control unit that controls the coffee grinder start and
stop. The grinding time can be programmed on the electronic control unit and the grinder-dispenser can
be made to restart after a desired number of ground coffee servings.
• An on/off main switch
2
with green LED.
